* The last digit of the SN prefix is the design modification state, this may increase during the build life of the tables.

NOTE: Some models have ‘Denyer’, ‘USA’, or ‘Euro (Kifa)’ accessory side rails, standard Eschmann accessories that locate onto these may not fit, please check with Eschmann Equipment before purchasing accessories.

1.1.3 The T20 Series operation tables and accessories must only be used as detailed within these ‘Instructions for use’. Failure to do so could result in injury to patients or users, or damage to the operation table and accessories. Always ensure that all warnings and cautions detailed within these ‘Instructions for use’, are strictly complied with. Appendix 1 is provided for Hospitals that wish to keep a log of those people trained in the safe use of this table. Eschmann Equipment offers full training in the safe use of these tables, please contact our After Sales Service Department for details.

1.1.4 ‘Instructions for use’ and ‘Service manuals’ (see section 3.3.9) as applicable should be readily accessible for reference prior to and when operating, cleaning and servicing the operation table. All manuals are available from Eschmann Equipment, see inside front cover for address.

1.1.6 All servicing and maintenance procedures should be carried out by engineers who have been trained by Eschmann. Training, a Service, or a Service Contract can be arranged through our After Sales Service Department (see inside front cover for contact details). Do not remove the table covers at any time (danger of accessible mains voltage), this should only be carried out during maintenance procedures. Ensure that the operation table is regularly serviced and checked for safety at least every six months.

1.2 About this manual

1.2.1 Within the text of these ‘Instructions for use’ the following terminology is used:

Left and right

the side of the table when viewed from the long trunk end (i.e. the head end with the table in its normal configuration, head section fitted to the long trunk as shown in Fig. 2.1). This is also the patient’s ‘left’ and ‘right’ when lying on the tabletop in a supine position, with their head on the head section and with the table in its normal configuration.

ii)

Auto-level

the automatic sequence of movements to return the table to a preprogrammed position by pressing and holding a single handset button. This does not affect the head or leg sections, or any other manually operated, or powered accessory, fitted to the table.

iii)

LEDs.

This abbreviation is used when referring to the various indicator lights on the table or handset which are light emitting diodes (LEDs).

iv)

Cranially and Caudally.

section moves away from column) and ‘caudally’ (leg section moves away from column) are used to describe tabletop movement (table in the normal orientation). Normal table orientation is with the head section in the long trunk, normal patient orientation is with the patient’s head on the head section.

1.2.2 These ‘Instructions for use’ have been split into specific sections for ease of finding information (see the main headings in ‘Contents’). Where applicable and within each section, adequate cross references to other sections are made to eliminate the need to duplicate information.

1.2.3 Section 5 (Operation) details how to use the T20 Series of tables and operate their controls correctly. It is strongly recommended that the user has read and is familiar with sections 1, 2 and 4 before passing onto section 5 and starting to use this operation table.

1.2.4 Within this manual the sections in bold type headed ‘WARNING’ give guidance on possible actions that could lead to injury of the patient, or theatre staff, and potential damage to the operation table. Sections headed ‘CAUTION’ give guidance on possible actions that could lead to damage of this operation table which could then lead to injury of the patient, or theatre staff.

OPERATION TABLE

1.3 Table description

1.3.1 The T20 Series of four section operation tables have been designed to provide facilities for General Surgery, including Minimal Access procedures, Urology and Gynaecology, Thoracic, Ophthalmic and ENT, Neurosurgery, Plastic and Maxillo-Facial surgery, and nontraction Orthopaedic Surgery, they allow for intra-operative radiography using a C-arm image intensifier. They are not suitable for Orthopaedic procedures requiring traction.

1.3.2 Careful design has minimised traps for potential contamination stopping fluid entering the table during normal use, cleaning and disinfection procedures. They are stable, rigid in use and the robust construction provides protection from patient trolley or C-arm knocks whilst still providing easy access for servicing.

1.3.3 Tabletop movements (i.e. Trendelenburg, height, tilt, break and traverse) are electrically powered and incorporate ‘soft start and stop’ motions for patient comfort and safety. The pedestal base is foot operated and the standard head and leg sections are hand operated (see sections 5.1 and 5.2 respectively).

1.3.4 The T20 Series of table are easy to operate, theatre staff can quickly learn how to use them correctly and safely. Tabletop control is provided by a corded handset, or an optional footswitch (for Trendelenburg and height control only) or an optional infrared handset. Hand controls override footswitch control at all times and if a corded handset is plugged into the table this will take precedence over the infrared handset.

1.3.5 Power for all powered table movements is provided by internal rechargeable batteries. There are two battery sets, main batteries and standby batteries. These are recharged by an internal battery charger which requires connection to mains voltage using the mains cord supplied. Note: If the main table batteries fail or become critically low (i.e. warning indicators were ignored and batteries have not been recharged) the table cannot be powered directly from the mains. However by depressing and holding the standby battery switch, powered table movements can again be achieved (using power from standby batteries).

1.3.6 In emergencies (e.g. handset failure or a critically low battery) a standby control panel on the column can be used to control the table (however this MUST be limited to emergency use ONLY, certain safety features are overridden when this panel is used, see section 4.6.5). It may be required to press the standby battery switch if the main battery charge level is too low.

1.3.7 The bases on T20-a and T20-s tables are fitted with enclosed multidirectional castors, that can be engaged at any table height, making it easy to move on most theatre floors. They have two foot pedals providing either castor, wheel or braked orientations. The T20-m table is provided

with four large castors that can be adjusted by a single foot pedal to provide wheel and castor modes and a braked position (see section 5.1).

1.3.8 Visual indicators have been restricted to essential functions and information only (e.g. table switched ‘on’ see section 5.3.2.2, battery level indication and battery charging state see section 5.3.1). Audible signals are only used to signal that the table has been switched ‘on’ for a long time without operation and that it should be switched ‘off’ see section 8.1, a ‘beep’ is also provided when switching ‘on’ (the audible inactivity ‘beep’ can be configured ‘off’ during a service if required).

1.3.9 Tabletops have a lightweight X-ray translucent surface (designed to reduce shadows on images) and an X-ray cassette tunnel with the facility for an X-ray cassette (430mm x 340mm) to be placed at any point beneath the full length of the patient’s body, see section 6.3. The standard side rails allow placement of clamps and most standard accessories. Simple button operated catches release the head and leg sections when required.

1.3.10 The tabletop can be adjusted into the following patient positions:

♦ Supine with C-arm access to patient from nipple

region to feet

♦ Supine with C-arm access to patient from groin to

head

♦ Supine Extension with C-arm access to break area

(Cholecystectomy-type procedure)

♦ Supine Flexion (‘Lawn chair’ position) ♦ Lateral ♦ Lateral Extension with C-arm access to break

(Nephrectomy position)

♦ Supine Lithotomy with C-arm access to whole of

the Urinary tract

♦ Supine Lithotomy with or without Trendelenburg ♦ Prone with or without extension at waist or hips (with

C-arm access)

♦ 90° Chair position with patient’s knees at the same

level as the heart, offset to the head end.

1.3.11 For additional information see section 6.0 for patient positioning notes, section 6.2 for the obese patient,

6.3 for radiographic procedures and 6.4 for illustrations and details of safe loading.

1.3.12 Castor covers (spats) are supplied as an optional item with the T20-m table. These can be fitted by an Eschmann Engineer at any time, please contact the After Sales Service Department.

OPERATION TABLE

3.0 INSTALLATION

3.1 General

3.1.1 In the U.K. the table is delivered un-crated with the head and leg section fitted. The mattress set is boxed individually and placed on the trunk sections. The handset, mains cord and literature are supplied loose. Any accessories ordered with the table will be packed individually. Some of the following unpacking and assembly information is not therefore applicable to U.K. customers. For overseas markets the table is usually packed in a container with the head and leg section fitted, together with a boxed mattress set a mains cord and the literature. The handset is packed within the container in an antistatic bag. Other accessories are usually packed separately, but some may be included in the main case and should be unpacked and stored separately during the table installation.

3.1.2 When delivered packaged, carefully remove the T20 operation table (having first removed any accessories and packing restraints from within the container) from the packing case as follows:-

i Remove the walls of the case leaving the table on

the base still in the braked position as packed. Remove any chocks from the pallet base to enable later table movement (iv below).

ii Position the ramp provided (in the packing case)

adjacent to the base of the case.

iii Follow the instruction provided in section 5.1 of this

manual and place the table base into the ‘Wheel’ orientation or mode.

iv With at least two people to support the table’s weight,

push it (do not pull it) off of the pallet base and down the ramp.

v Note that the table should not be wheeled over rough

ground, always use a trolley until a smooth floor area has been reached.

vi Should it be necessary to lift the operation table refer

to section 3.2 where suitable lifting points and methods are detailed.

3.1.3 Unpack the mattress set and fit a mattress to each tabletop section as detailed in section 5.2.6.

3.1.4 Any packaging materials should be recycled or disposed of in accordance with current legislation.

3.1.5 The T20 Series of table are powered by internal rechargeable batteries which are connected and charged before delivery (see disposal note in section 8.6.3). The tables also have standby batteries. An internal mains powered battery charger is incorporated in the table’s base, to charge both the main batteries and the standby batteries.

CAUTION

It is most important that fuses of the correct type, size and rating are installed (see Technical Data, section 9.5.4).

3.1.6 The T20 Series of table require a mains electrical supply corresponding to the voltage shown on the Serial Number Plate located on the table base. Only use the Eschmann mains supply cord provided with the table. If the plug supplied fitted to the cord is not suitable it should be replaced with a suitable plug wired as below. If the plug is a fused type, a 10A fuse must be fitted. The mains supply cord must always be wired as follows:

Brown internal cord to LIVE Blue internal cord to NEUTRAL Green internal cord to Earth (Note: The T20-a, T20-s and T20-m tables are

Class II, Type BF, there is no EARTH connection through to the table)

3.1.7 The table batteries should be recharged (see section 5.3.1) and the table operated through the cycle of movements detailed below to check and ensure correct function, before the tables are first used.

Full Trendelenburg / reverse Trendelenburg Maximum to minimum height Maximum tilt, left and right Maximum traverse, caudally and cranially Maximum to minimum break

CAUTION

To complete and maintain the antistatic pathway the table must be used on an electrically conductive or antistatic floor and with mattresses supplied by Eschmann Equipment.

3.1.8 The table has an antistatic pathway from the tabletop, through an internal resistor, to the castors. To complete the antistatic pathway, the table must be used on an electrically conductive, or on an antistatic floor (also see the warning in section 6.1).

3.1.9 As with all medical electrical equipment care should be taken with regard to electromagnetic compatibility (EMC) during installation. These instructions are written in line with the latest international standards (EN 60601-1-2:2001) and are designed to minimise the risk of electromagnetic compatibility issues. The T20 Series of table should be installed and put into service in accordance with the EMC information provided in the Technical Data section of these ‘Instructions for Use’ (Section 9.11).

3.1.10 The table should be cleaned and disinfected prior to its first use as detailed in section 8.2 and 8.3 and then commissioned in accordance with any local procedures applicable to new equipment, this should include staff training. Eschmann supply a range of wall charts with the table, additional training aids and on-site training can be arranged, contact Eschmann for more information.

3.2 Lifting the operation table

WARNING

The table is heavy and at least four strong people are required to lift it. Ensure that adequate precautions are taken (e.g. wear protective shoes, use the correct straps).

3.2.1 The T20 Series of table should only be lifted as a last resort. Ideally it should be placed on a trolley directly from the delivery vehicle, or moved on the base of the delivery packing case (overseas only) and then rolled down the ramp provided.

3.2.2 If required the T20 table should only be lifted by placing suitable webbing straps underneath the table base in the positions indicated in Fig. 3.1 (having placed the T20-a and T20-s tables into their ‘castor’ orientation to increase ground clearance) and observing the notes that follow. The table should only be lifted the minimum amount required and not carried. Lift the table sufficiently high to allow a fully decked pallet to be slid underneath. The table should be placed into its ‘braked’ orientation whilst on the pallet. Transport the table on the pallet using a forklift truck or similar equipment ensuring the table is strapped securely to the pallet.

3.2.3 Extreme care should be taken to pad the straps where they pass the base covers and the table top sections to avoid damage. Take special care not to cause damage to the lower edge of the base covers.

3.2.4 Before lifting remove all tabletop sections, accessories and mattresses, to minimise the weight to approx. 248kg (T20-a and T20-s tables) or 196kg (T20-m table). Place the table top into a level plane in both directions (i.e. tilt and Trendelenburg) and traverse the top so the long trunk is central to the column as shown in Fig. 3.1. Lower the short trunk and then the table top to their maximum limits.

3.2.5 When lowering the table after the lift take care not trap feet under the tables base. Inspect the table for any signs of damage and check all functions prior to placing the table back into service.

3.3 Technical

3.3.1 The following sections are provided for the user to note prior to using a T20 Series of operation table.

3.3.2 The T20 Series of table meets the requirements of international standards (see section 9.8) and conforms dimensionally to meet most requirements, for the full table technical specification details refer to the Technical Data, section 9.0.

3.3.3 The table should only be used on an antistatic floor and is classified as type ‘BF’ (i.e. the table has isolation from earth equivalent to that of type ‘BF’ equipment when the mains cord is attached).

3.3.4 The antistatic properties of the table depend upon the use of the recommended mattresses (i.e. Eschmann antistatic mattresses ONLY) also see section 3.1.8.

3.3.5 Only Eschmann accessories listed in this manual should be used on the table and in accordance with the ‘User Handbook’ supplied with the accessory. Accessories available from Eschmann are listed in section 7.0. Other accessories, especially those that could compromise table stability, must not be used. Use of other equipment with T20 tables should only be considered after evaluating the safety of the patient and personnel. For accessories that fit onto the side rail ensure that they are compatible with the side rail fitted to the table. These tables can be supplied with standard UK, Euro USA or Denyer style side rails, see section 1.1.2

3.3.6 Provision of a diagnostic port within the table enables access for reprogramming the tables software, down-loading of fault information and service functions. Use of this port MUST be limited to trained service personnel only, and should only be used in accordance with the correct Eschmann manuals (see 3.3.9 below).

3.3.7 The table has four fuses (two on the T20-m) that the user has access to in the event of failure. The position of these are shown in Fig. 2.2 and 2.3 and are replaced as detailed in section 5.3.5.

3.3.8 Eschmann can provide customers with manuals (see 3.3.9 below), for use by them in maintaining their own equipment. These manuals contain schematic diagrams, component part lists, descriptions and calibration instructions which will assist the customer’s Eschmann trained personnel to service the equipment or replace parts (which should only be obtained from Eschmann).

3.3.9 The following manuals are applicable to the T20 Series of operation table and their accessories (the part number is in brackets following the manual reference) they are available to order, see inside front cover for contact details:-

T-SM52 (113175) - Service manual T-IPL40 (113177) - Illustrated parts list T-IM94 (111012) - Application software manual T-IM56 (698907) - General accessory leaflet Note: Some accessories are provided with their own ‘User/Service Handbooks’.

3.3.10 Appendix 1 provides a log that can be used to record those people trained in the safe use of this operation table. It is suggested that this is used to ensure that ALL personnel using this table, are aware of all the warnings and cautions contained within these ‘Instructions for use’.

OPERATION TABLE

4.0 SAFETY NOTES & CAUTIONS

4.1 Warnings

The warnings and cautions that follow must be followed, they are repeated as applicable within the text of these ‘Instructions for use’ to emphasise their importance. Ensure you are familiar with them before using the table.

WARNINGS

The T20 Series of table have been designed to minimise the possibility of accidental electrosurgery burns. Contact with any metal surfaces (e.g. table side rail, or other equipment etc.) can cause burns during electrosurgery and must be avoided.

The T20 tables are not rated as AP or APG and should not therefore be used in the presence of explosive gases.

The T20 tables have been designed for patients weighing up to 300kg (47 stone) with their centre of gravity (normally the umbilicus) positioned close to the column on the trunk sections. However patient positioning and additional loads from accessories can compromise table stability and strength. Ensure that loading does not compromise table stability or damage the table (see graphs in section 6.4).

To comply with BS EN 60601-1:1990 some accessories have been designed for a maximum evenly distributed load, see the ‘User Handbook’ supplied with each accessory.

With the table in (or during transition into) the ‘castor’ or ‘wheel’ orientation, the centre of gravity of the patient (normally the umbilicus) should lie no more than 200mm away from the centre of the column. Whenever this is not practical the table should be adequately supported (e.g. by at least two able people).

The head and leg sections are designed to support and position the corresponding part of the patient’s weight only. Damage leading to failure of the section may be caused if excessive weight is applied. Take care when handling these sections to avoid strain and ensure no body parts or objects are trapped when replacing or adjusting them.

Only use Eschmann accessories and sections that are compatible with this table. When parts are replaced during maintenance procedures, ensure that ONLY parts supplied by, or from, Eschmann Equipment are used. Alternatives,

although similar, may affect the safety of the table. Eschmann cannot be held responsible for service, modification or adjustments to the equipment, when performed by other than Eschmann accredited personnel.

Where given, descriptions and illustrations of patient operating positions, and positioning procedures, are for guidance only. It is the responsibility of the operating surgeon to make sure that the positions, and the positioning procedures are appropriate for the operation to be performed, and the safety of the patient. (See section 6.0).

During any table positioning procedure care should be taken to ensure the patient’s safety. In particular during Trendelenburg and tilt movements the patient should be supported to ensure they remain secure on the tabletop. The patient’s weight should be supported whenever the sections are adjusted or removed from the table during repositioning.

During ANY movement of the table or tabletop, ensure that no part of either patient or hospital staff, or object (e.g. drapes, infusion tubing, diathermy connections, ECG cords etc.) can become trapped between any moving and/or stationary equipment, or in a pinch point, causing injury or damage to equipment. Particular table movements that should be operated with care are reducing the height and Trendelenburg, which can cause trapping situations. Always ensure adequate slack is available in drapes and tubing for the movement required (e.g. maximum Trendelenburg).

When moving the table (e.g. in or out of theatre) with a patient (maximum weight 135kg for T20-a and T20-s, or 200kg for T20-m, see section 5.1) always ensure that the patient‘s limbs are secure on the tabletop to prevent crushing or trapping them against another object, always use cot sides (available as an accessory).

Always keep the patient under observation (e.g. check respiratory and circulatory system and for the possibility of pressure sores etc.) and correctly positioned whilst on the table.

Ensure that electrical equipment connected to the communication port (available during maintenance procedures only) complies with appropriate electrical safety standards. Note that standards compliance of this product may be affected if noncompliant equipment is attached to the communication port.

T-IM114b P15/62

CAUTIONS

Do not place either heavy accessories, or, long accessories that could impose high torques, to the side rails, as this may lead to damage of the rails.

♦ Ensure that only the Eschmann mains cord supplied

with the table is used to connect the table to the mains.

♦ Ensure that only Eschmann supplied parts are used

during part replacement.

DO NOT:

Do not exceed the duty cycle for any table motor drive as detailed in the technical data section 9.5.5.

Moving the table over soft floors (e.g. carpet or ‘cushion’ flooring) will increase resistance to movement compared to normal hospital ‘hard’ flooring and care should be taken.

4.2 Do’s and Don’ts

Attention to the following points will prolong the life and efficiency of the T20 Series of table and will help to avoid the risk of accidents, or damage. Other safety notes and warnings are also given within the text of this manual and these should be noted during use of the table.

♦ Check that all the sections (e.g. head and leg) and

accessories are secure, and put the table base in the ‘braked’ position before use.

♦ Ensure that all cables are not stretched leading to

disconnection or damage during movement or readjustment of the operation table or patient.

♦ Remove table accessories and their clamps (in

particular rotary clamps) from side rails, when they are not being used.

♦ Read and follow the instructions for cleaning, and for

the care of the table and mattresses.

♦ Switch ‘off’ and disconnect from the mains electrical

supply prior to cleaning and/or disinfecting the table and when it is not being recharged.

♦ Ensure that the table and accessories are serviced at

regular intervals (every six months is the recommended frequency) only by Eschmann trained personnel, or by accredited agents.

♦ Do not lift the table by its tabletop. ♦ Do not move the table with a patient without cot sides

in place on either side of the tabletop.

♦ Do not push the table over rough surfaces, use a

trolley.

♦ Do not drop the table (or individual sections). ♦ Do not put heavy weights on the table sections,

observe the maximum advised loading.

♦ Do not put sharp objects on, or against, mattresses,

pads, or the radiographic tabletop.

♦ Do not place any objects on the base covers ♦ Do not drop heavy objects onto the radiographic

tabletop or base covers.

♦ Do not spill oil, ether, or other fluids onto the mattresses

or the pads.

♦ Do not pull the table by any of the tabletop sections,

or accessories, always push it.

♦ Do not service this equipment unless you have been

trained by Eschmann.

4.3 Daily ‘Before use’ test

It is recommended that a ‘Daily test’ is carried out before using the table every day. First check that the batteries are charged if they are not charge them (see section 5.3.1.1 and 5.3.1.2) and ensure that a suitable practice is put in place so they are charged at the end of every shift in future. Then check the table responds to the following movements from the handset (each movement only needs to be brief, one or two seconds each):

Trendelenburg / reverse Trendelenburg Height Up / Down Tilt Left / Right Traverse Caudally / Cranially Break Up /Down

Then check at least two of the above plus Trendelenburg using the Standby control panel.

4.4 Accessories

The accessories available from Eschmann for the T20 Series of table are listed in section 7.0. Use of other equipment with the T20 tables should only be considered after evaluating the safety of the patient and personnel. Inadvertent use of incorrect accessories could damage the table and lead to injury. Always ensure that the information in the ‘Instruction’ or ‘User Handbook’ supplied with the accessory are complied with and follow all the safety notes

P16/62 T-IM114b

contained within them during use. For accessories that fit onto the side rails ensure that they are compatible with the side rails fitted to these tables. These tables can be supplied with standard UK, USA or Denyer style side rails.

4.5 Manual handling

WARNING

Ensure care is taken when moving adjusting or lifting any part of the table or patient. Note the guidelines provided.

4.5.1 During adjustment or changing the configuration of the T20 series of operation tables, there are occasions when the user should be aware of the safe practises to be employed during manual handling or adjustment of parts of the table. For information, the weights of the heaviest sections and accessories commonly used are listed in Appendix 4. Appendix 4 also contains other information on manual handling. When lifting, carrying or fitting these components it is recommended that care is taken and that two or more people are employed when required.

T20

Series

OPERATION TABLE

4.5.2 These ‘Instructions for use’ advise supporting the weight of the patient during adjustment of any section, obviously this requires the intervention of several personnel, some supporting the patient’s limbs and others adjusting the table sections.

4.5.3 When moving the table note that extra effort is required to start the table moving, take care not to strain limbs or back. The table should not be moved when heavily loaded note the warnings and cautions provided. It is good practice to use two or more people when moving a table.

5.0 OPERATING THE TABLE

manual operations achieved by using one or both of the foot pedals on the table base.

This section has been split into sections as follows:

5.1 Moving/operating the table base.

5.2 Using the removable sections.

5.3 Using the table’s powered/electrical functions.

5.1 Operating the table base

WARNING

Always push the table (do not pull it) at a suitable height ensuring that it is stable at all times, take care not to collide with personnel or equipment. Maximum stability will be at minimum height. Ensure that the patient is adequately supported and restrained (especially limbs) using cot sides as appropriate (also see section 5.1.3). Ensure that all connections via cord or tube, to the patient or table, have either been disconnected, or are only attached to equipment that will move with the table to avoid inadvertent disconnection.

When changing from ‘castor’ or ‘wheel’ orientation, to ‘braked’, ensure that no objects (e.g. cords, tubing etc.) can become trapped beneath the table base and floor (T20-a and T20-s tables only). Do not move the table with a patient weighing more than 135kg (T20-a and T20-s tables) or 200kg (T20-m table) and ensure stability is maintained.

If table is difficult to move check for objects under castors and that castors are maintained and kept clean and free from foreign objects (also see section 1.3.12).

The table should always be left in the ‘braked’ orientation with both pedals in their raised positions. Do not leave the table with the wheel pedal up and the castor pedal down. When familiar with sections 5.1.1.1 - 5.1.1.2, use Fig. 5.3 as a quick reference guide for pedal operation.

5.1.1.1 ‘Wheel’ orientation (from ‘braked’)

T20-a wheel pedal operation is easily achieved if the pedal is pressed down with the right foot whilst steadying yourself with hands on the tabletop. Stand on the side of the table on which the footpad is located. T20-s wheel pedal operation is easily achieved if you steady yourself with your hands on the tabletop, note that you can stand on either side of the table to operate the pedal. For either type of pedal use a steady ‘press’ rather than a ‘rapid depression’ of the pedal, this provides easier identification of the ‘click’ and avoids pressing the pedal passed its locking position.

To place the table into the ‘Wheel’ orientation from the ‘braked’ orientation, press the wheel pedal (item 11, Fig. 2.2) down steadily until you hear an audible ‘click’ (action indicated in Fig. 5.1a or 5.1b). This ‘click’ indicates that the pedal has locked in the down position. Do not continue to press the pedal after the ‘click’ as this will release the internal catch and the pedal will not lock down. If this does happen the pedal must be allowed to rise fully (this resets the internal catch) before pressing it down again.

When placed into the ‘Wheel’ orientation the table base is supported on two wheels at the short trunk end and two castors at the long trunk end. To move the table in ‘wheel’ orientation always push it (do not pull it) from the long trunk end, moving the end nearest to you, left or right, to steer the table in the required direction. The table is in ‘wheel’ orientation when the wheel pedal is in the lowered position and castor pedal is in the raised position.

5.1.1.2 ‘Castor’ orientation (from ‘wheel’)

The table base has three formats, the T20-a and T20-s tables (basically similar, differentiated by the design of the foot pedal) see section 5.1.1 and the T20-m table which has a single foot pedal, see section 5.1.2.

5.1.1 T20-a and T20-s table base

The T20-a and T20-s tables can be moved easily on builtin castors and wheels. Normally the table rests on brake pads at the long trunk end and wheels at the short trunk end, these provide a secure and static location on the operating theatre floor. Lower the table to a suitable height to achieve a stable position before moving the table.

To move the T20-a and T20-s tables they are placed onto their wheels and castors in two ways, providing both a ‘castor’ orientation and a ‘wheel’ orientation. The latter enables easy movement of the table in a straight line (down a corridor for example). Moving the table into either of these orientations does not require battery power, they are

T20-a castor pedal operation is easily achieved if the pedal is pressed with the left foot whilst steadying yourself with hands on the tabletop. Stand on the side of the table on which the footpad is located. T20-s castor pedal operation is easily achieved if you steady yourself with your hands on the tabletop, note that you can stand on either side of the table to operate the pedal. For either type of pedal use a steady ‘press’ rather than a ‘rapid depression’ of the pedal, this provides easier identification of the ‘click’ and avoids pressing the pedal passed its locking position.

To place the table into the ‘castor’ orientation from the ‘wheel’ orientation, press the castor pedal (item 10, Fig. 2.2) down steadily until you hear an audible ‘click’ (action indicated in Fig. 5.1a and 5.1b). This ‘click’ indicates that the pedal has locked in the down position. Do not continue to press the pedal after the ‘click’ as this will release the internal catch and the pedal will not lock down. If this does happen the pedal must be allowed to rise fully (this resets the internal catch) before pressing it down again.

Series

OPERATION TABLE

When placed into the ‘castor’ orientation the table base is supported on four castors, two at each end of the table. This orientation enables the table to be moved in any direction including sideways and swivelling within its own length. To move the table always push it in the required direction, never pull it. The table is in ‘castor’ orientation when both pedals are in their lowered positions.

5.1.1.3 ‘Castor’ orientation (from ‘braked’)

To place the table into ‘castor’ orientation from the ‘braked’ orientation follow 5.1.1.1 to place the table into ‘wheel’ orientation and then follow 5.1.1.2 to complete the move into the ‘castor’ orientation.

Note: It is not critical that sections 5.1.1.1 and 5.1.1.2 are carried out in this sequence the reverse is equally suitable and correct.

5.1.1.4 ‘Braked’ orientation

To place the table into the ‘braked’ orientation move the pedals (items 10 and 11, Fig. 2.2) into their raised position. If either pedal is in the lowered position raise them, in any sequence.

For the T20-a table stand on the standby control panel side of the table and use the foot advised in 5.1.1.1 or 5.1.1.2 as appropriate. For the T20-s table you can stand on either side of the table. Steady yourself with your hands on the tabletop and press the pedal ‘firmly down’ see Fig. 5.2a and 5.2b, this disengages the internal locking catch. Release pressure on the pedal and allow it to rise. The table will gently lower onto its brake pads and wheels, the motion is softened and braked by an internal damper.

The table is in ‘braked’ orientation when both pedals are in their raised positions.

5.1.2 T20-m table base

WARNING

Before using the table, position the castors under the base covers to help protect them from any falling contamination.

The T20-m table base has been provided with four large castors. The table rests on these castors at all times providing either a secure and static location on the operating theatre floor (‘braked’), or two modes for easy movement (‘castor’ and ‘wheel’ modes). Adjust the table to a suitable height to achieve a stable position before moving the table.

The T20-m table should always be left ‘braked’ with the foot pedal in its lowest position. When familiar with sections

5.1.2.1 to 5.1.2.4, refer to the label on the table base as a quick reference guide to pedal operation (label is illustrated in Fig. 5.4).

To move the table it is placed into its ‘castor’ mode or ‘wheel’ mode. The latter enables easy movement of the table in a straight line (down a corridor for example). The ‘castor’ mode provides full free wheeling mobility with 360° rotation and movement sideways.

Adjusting the table into either of these modes does not require battery power, they are manual operations achieved by using the single foot pedal on the table base (see item 4, Fig. 2.3).

5.1.2.1 Foot pedal operation

Foot pedal operation is easily achieved when the pedal is operated with either foot whilst steadying yourself with your hands on the tabletop. Stand on either side of the table or the pedal end, which ever is the most suitable and easy.

PUSH IN A STRAIGHT LINE

CASTOR

WHEEL

Do not operate the pedal from the end of the table when a long table section (e.g. a leg section) has been fitted to the long trunk end, this may require unnecessary stretching by the operator to reach the pedal. Operate the pedal from the side of the table.

Use a steady motion rather than a ‘rapid’ movement of the foot pedal, this provides easy identification of the ‘snap’ into any of its three positions.

5.1.2.2 ‘Braked’

To place the table into the ‘braked’ orientation press the foot pedal (item 4, Fig. 2.3) down to its lowest position. Operate the pedal as detailed in section 5.1.2.1. and press the foot pedal down until it snaps into its lowest position.

The pedal can be moved from its highest ‘wheel’ position through its central ‘castor’ position and into the ‘braked’ position in one easy movement.

The table is ‘braked’ when the foot pedal is in its lowest position.

5.1.2.3 ‘Castor’ mode

To place the table into the ‘castor’ mode, move the foot pedal (item 4, Fig. 2.3) into its central position. Operate the pedal as detailed in section 5.1.2.1 and move the foot pedal until it snaps into its central position.

The pedal is moved up from its lowest ‘braked’ position by lifting the pedal up with the top of the foot, or down from its raised ‘wheel’ position by pressing the pedal down with the ball of the foot, until the pedal snaps into the central ‘castor’ position.

The table is in ‘castor’ mode when the foot pedal is in its central position.

Note: When the table has been moved to the required location always leave the table ‘braked’.

PUSH IN ANY DIRECTION

P20/62 T-IM114b

Press pedal down fully with the castors in any position to brake all four castors (see WARNING in section 5.1.2).

Lift pedal up, or press pedal down, into the central position to enable the table to be 'castored'. All four castors will swivel allowing full table mobility.

Select 'castor' mode' (pedal in the central position) and push the table until the short trunk end castors are correctly aligned as indicated. Lift the pedal up fully into the 'wheel' position (to stop the short trunk end castors swivelling). This will enable the table to be 'wheeled' in a straight line. Push and steer the table from the pedal (head) end.

Detail of the required short trunk end castor postion, which should be obtained, before lifting the foot pedal into its top position to place the table base into the 'wheel' mode.

5.1.2.4 ‘Wheel’ mode

WARNING

Do not push the table in the ‘wheel’ mode until you are sure the castors have moved into their correct orientation for the ‘wheel’ mode, as detailed in the second stage below and Fig. 5.4. If the table is pushed with the castors locked out of position this will cause undue wear leading to failure of the short trunk end castors.

Placing the table into the ‘wheel’ mode is a four stage procedure which will ensure that the short trunk end castors are locked in position correctly.

First, if the table is ‘braked’ move the foot pedal (item 4, Fig. 2.3) into its ‘castor’ position as detailed in section

5.1.2.3. Second, push the table forwards from the long trunk end

until both the short trunk end castors have swivelled into the position ‘B’ shown in Fig. 5.4. They do not need to be exactly in line, but they should not be as shown in ‘A’ Fig. 5.4 (i.e. leading their mounts).

Third, lift the pedal up with the top of the foot, as detailed in section 5.1.2.1, until the pedal snaps into its highest ‘wheel’ position.

Fourth and finally, continue to push the table in a straight line, the short trunk end castors will lock automatically in line with the table base. This enables the table to be moved easily down a corridor, being steered from the long trunk end.

The table is in ‘wheel’ mode when the foot pedal is in its highest position and the short trunk end castors have locked in-line with the table base.

Note: When the table has been moved to the required location adjust the table into ‘castor’ mode to enable full mobility and positioning and then leave the table ‘braked’ (press the pedal fully down).

5.1.3 Moving table with a patient

The normal table position when moving it with a patient is level in both directions (i.e. tilt and Trendelenburg) and with the patient in the supine or lateral recovery position. Fig. 5.5 shows an alternative position that can be used, the notes in Fig. 5.5 also apply when moving the table with the patient in the supine or lateral recovery position.

Notes:

Always use cot sides. Lower table to a suitable height. Ensure patient limbs are secure. Check patient weight and position complies with Fig. 6.3 and Fig. 6.4. Always push table from the head end (do not pull). Position also applies to T20-a and T20-s tables (T20-m table illustrated).

OPERATION TABLE

5.2 Using the removable sections.

WARNING

Ensure that nothing becomes trapped (e.g. fingers, tubing, cords) when attaching tabletop sections. When removing a section be prepared to support the full weight of the section when the guide pins disengage. Always carry the section holding the side rails. Never hold or pick up the section using the black gas support struts and take care not to operate the release handle accidentally. Do not operate the release handle when the section is removed from the table. For users of small stature, when handling larger sections (e.g. the leg section) two people should work together to avoid strain injuries. Also to minimise weight for all users remove mattresses before fitting or removing a section. Users of earlier Eschmann tables (e.g. MR and RX Series) should note that T20 guide pins are shorter and disengage earlier. Always ensure that the sections have been correctly and securely fitted before use and only use the correct Eschmann sections.

To attach the section to a table after re-aligning the pins insert the pins into the tabletop for 90% of their length, actuate the release handle and adjust the section until horizontal and then push the section fully home until the locking catches engage (also see section 5.2.2).

During long term storage of a section it should be positioned with the pins up, this ensures continued lubrication of the gas spring seals (e.g. attached to the table and fully lowered). If stored separately from the table take care not to actuate the release handle during storage since this will alter alignment of the pins. Should this happen inadvertently see section 5.2.1. For short term storage and to aid manual handling (e.g. during section reversal) use of the ‘T’ series Head/Leg accessory trolley (REF TA-040013) is recommended.

5.2.1 Re-aligning a section’s pins

Realignment of a section’s pins is only required if they have become mis-aligned whilst the section has been removed from the table (see Fig. 5.6 for illustration of aligned and mis-aligned pins).

WARNING

Take care when realigning a sections pins. Ensure that fingers are clear of the gas springs during actuation of the release handle.

To realign the pins of a table section place the section on its side (see Fig. 5.6) and support it by its upper side rail only keeping fingers etc. well clear of the gas springs (see 1, Fig. 5.6). Then actuate the release bar (see 2, Fig. 5.6) until the gas springs have moved both pins to the ends of their travel as shown (see 3, Fig. 5.6).

Fig. 5.6 Section pin alignment

5.2.2 Attaching a removable section

When attaching a section first check to see if the pins are aligned with each other. It is possible that during storage the release handle may have been actuated and the pins are no longer aligned as shown in Fig. 5.6. If they are aligned attach the section as detailed below, if they are not, align them and attach the section as detailed in section 5.2.1.

To attach the removable tabletop sections (i.e. head or leg) hold the section firmly with two hands aligning the pins of the section (item 1, Fig. 5.7) with the location holes (item 2, Fig. 5.7) in the fixed tabletop section as shown in Fig. 5.7.

Fig. 5.7 Aligning section pre-attachment

T-IM114b P23/62

Gently insert the section pins into the tabletop and slide the section into the tabletop evenly until the locking catches engage with an audible click. The section will slide in easily if the weight of the section is gently supported with both hands. Take care not to trap anything (especially fingers) between the section and the tabletop.

Check that the section is fully inserted and the safety catches have engaged by gently pulling on the section. Both release buttons (items 6 and 8, Fig. 2.1) should be out when the section has been correctly located and locked.

5.2.3 Removing a tabletop section

When removing a tabletop section (e.g. a head or leg section) ensure that it is horizontal before removal as this will aid later replacement (pins will be aligned with the section). If the section is not horizontal adjust it to horizontal before removal (see section 5.2.4).

Remove the section from the tabletop by supporting the section’s weight and pressing in the right-hand trunk section button (viewed from end of table) as indicated by 1 in Fig. 5.8. The button will stay in when pressed correctly.

Press in and hold in the left-hand trunk section button (viewed from end of table) as indicated by 2 in Fig. 5.8 whilst pulling the section evenly away from the fixed section about 2 - 3cm (see 3, Fig. 5.8). When employing two people one should press the button whilst the other pulls the section out the 2 - 3cm. Gently supporting the weight of the section (i.e. slightly lifting whilst pulling) will make this action easier. Then release the left-hand trunk section button.

Now using both hands (one on each side of the section as shown in 4 of Fig. 5.8) continue to gently pull the section out evenly from the trunk section until the guide pins are free. Again gently lifting and supporting the weight of the section will make this action easier. When employing two people, one should hold the second button in whilst the other pulls the section out evenly, both can then support the weight when the pins are free.

Fig. 5.8 Removing a table section

When raising the section the gas springs will assist the movement, when lowering the section gentle pressure may be required to overcome slight resistance of the gas springs. Adjust the section by rotating it up or down to the required position (see 2, Fig. 5.9). When the correct position has been obtained release the locking bar. The section is now locked in place automatically by the gas springs (see 3, Fig. 5.9).

5.2.4 Removable section adjustment

The head and leg sections are operated in the same way. The section’s weight is supported during adjustment and held locked in position by two gas springs (items 5 and 11, Fig. 2.1). Lowering the section’s release handle during adjustment automatically locks the section in place.

To adjust either section (having noted the warnings at the beginning of section 5.2) grasp the end of the section on both sides with thumbs up and the finger tips resting on the release handle (items 10 or 12, Fig. 2.1) underneath the section. Whilst supporting the section in place (it may move when the release handle is raised), gently lift the release handle with the finger tips until the section is free to move up or down (see 1, Fig. 5.9).

OPERATION TABLE

5.2.5 Changing sections during a procedure

The table sections can be changed during a surgical procedure but extreme care must be taken to adequately support the patient throughout such adjustments to the table configuration. Also note the warning at the beginning of section 5.2.

When replacing a section during a procedure take extreme care not to trap any part of the patient, surgical drapes, surgical equipment, cords or tubing. Also note the warnings in section 4.1.

It is suggested that the mattress is located onto the section before fitting the section onto the tabletop when repositioning it during a procedure (allow for the extra weight).

5.2.6 Attaching/Removing mattresses

WARNING

Larger mattress sections can be heavier and more bulky than normally envisaged (see section 7.0 and the note in section 9.1). Take care when handling to avoid stain injuries, use two people if required.

Only use Eschmann mattresses and ensure they are free of cuts and tears, replacing as required. Do not use without a mattress fitted to the table.

Mattresses are attached to the tabletop by two mushroom shaped pins per section. These pins ensure that the mattress stays in place on the tabletop in all table configurations. To ensure that the mattress is correctly located onto the pins proceed as follows:-

i The larger mattress sections can be bulky to handle

individually if of small stature, use two people to avoid strain.

ii Ensure the mattress is the correct one for the section

you are fitting it to and orientate it relative to the tabletop so the mushroom pins are lined up with the mating recesses in the underside of the mattress.

iii Lower the mattress onto the tabletop and gently ease

one location recess at a time onto and over the respective mushroom pin. The mattress should lie flat on the tabletop when this has been achieved without evidence that the pin is holding the mattress off the tabletop surface.

To remove mattresses reverse the above procedure gently easing the mattress off the pins, one pin at a time. Ensure minimal sideways force is applied to the mattress during this procedure to prolong mattress life.

Always ensure that mattresses are free from any cuts and abrasions, such damage can compromise patient safety by promoting cross contamination. Replace worn mattresses with new ones as soon as possible.

5.3 Powered and electrical functions.

This section is split into four sections as follows:

5.3.1 Batteries and mains

5.3.2 Powered motions

5.3.3 Using the handset

5.3.4 Using the standby control panel

5.3.5 Changing fuses

Note: Whilst it is safe to use the table when connected to the mains it is good practice to use the tables batteries to power the table, rather than connect the table to the mains.

5.3.1 Batteries and mains

5.3.1.1 Battery charging introduction

WARNING

Ensure that the mains supply used is suitable (i.e. 100-240V, 50-60Hz) before attaching the table to the mains supply. Only use the mains cord supplied with the table and charge the batteries daily.

CAUTION

Continued use of the table batteries when ‘critically low’ can damage the batteries. Charge batteries regularly to maintain peak performance. Do not remove the table from charge until both charging LED’s are ‘green’ to avoid false battery level indication on the handset.

Batteries within the table base are mains rechargeable and should power the table continuously for 3 days normal use (from a full charge). However to maintain peak battery performance the table batteries should be placed on charge at the end of each day or shift. Daily charging should be encouraged as good practice, do not wait for either ‘low’ battery indication before charging. Battery charge level is indicated by LEDs on the corded handset, see Fig. 5.10. The table should be placed on charge as detailed in section

5.3.1.2. Also see battery management sheet Appendix 3. Note: Over the first few charge cycles (from new) battery capacity increases until they reach a stable maximum level.

Batteries should be checked for adequate charge before using the table for any surgical procedure. The corded handset has two battery level indicators, one for the main battery and one for the standby battery, see Fig. 5.10. These indicators will only operate when the corded handset is plugged into the table and the table is switched ‘on’. Each indicator contains three coloured LEDs, these indicate the information shown over the page.

T-IM114b P25/62

Main battery level indicator:

Green LED ‘on’ = Battery level satisfactory. Amber LED ‘on’ = Low battery. An indication that

the remaining battery charge is only adequate for one day’s average use. Batteries MUST be recharged at the end of the current shift.

Red LED ‘on’ = Critically low battery. An indication that the remaining battery charge is critically low. Batteries MUST be recharged as soon as possible and before the next procedure. Charging during the current procedure is not recommended.

Standby battery level indicator:

Green LED ‘on’ = Battery level satisfactory. Amber LED ‘on’ = Low battery. Battery level is low

and only adequate for two or three Trendelenburg movements, they MUST be recharged at the end of the current shift.

Red LED ‘on’ = Critically low battery. Battery level is critically low and only adequate for one Trendelenburg movement. They MUST be recharged as soon as possible and before the next procedure. Charging during the current procedure is not recommended.

Handset (battery charge level)

5.3.1.2 Battery charging

To recharge the table batteries (normal and standby) connect the mains cord supplied with the table (do not use any other mains cord) into the mains inlet (item 18, Fig. 2.2 for T20-a and T20-s tables, or item 3 of 2.3 for the T20-m table).

Connect the mains cord to a suitable mains supply (check mains voltage is 100-240V, 50-60Hz) and switch the supply ‘on’ if controlled by a switch.

The battery charging LEDs (items 7 and 8 of Fig. 2.2 for T20-a and T20-s tables, or item 2.3 for the T20-m table) will illuminate ‘red’ to indicate ‘bulk’ recharge, ‘amber’ to indicate that the batteries are in a 2 hour ‘top-up’ charge and will illuminate ‘green’ to indicate a fully charged battery on ‘trickle’ charge (Note. The T20-m table only has one LED indicating both main and standby charging state).

The batteries should be fully charged within six hours (if the table is not in use) but it is safe to leave the mains supply ‘on’ when the batteries are fully recharged and both LEDs are ‘green’ (or in the case of the T20-m table the single LED is ‘green’). See CAUTION in section 5.3.1.1.

Note: Always ensure the table is switched ‘off’ to minimise the battery charging time.

It is recommended that the mains cord is stored on the ‘T’ Series accessory trolley (an accessory) to avoid loss and inadvertent use of an incorrect mains cord. It should be wrapped around the cable cleats.

When the main battery ‘critically low’ warning is indicated the table cannot be operated by either handset or the footswitch. To continue to operate the table either connect it to a suitable mains supply and recharge the batteries (see 5.3.1.2) or use the standby batteries (see 5.3.1.4). Note: The standby control panel can be used even when the ‘critically low battery’ indication is given but note the warning in section 5.3.4.

5.3.1.3 Battery changing

Batteries in the table base should only be changed by service personnel. They should last for many years if recharged regularly and should not require user intervention (also see section 8.6.3 for the caution concerning disposal).

5.3.1.4 Standby batteries

WARNING

The standby batteries are for emergency use only and will only provide power for a few movements.

The table is provided with standby batteries to cover the unlikely event of a main battery failure or fault. To use the standby batteries, the standby battery switch (see item 1, Fig. 2.2 for T20-a and T20-s tables, or item 1 Fig. 2.3 fot T20-m table) must be pressed and held depressed whilst the required motions are conducted using the normal hand and foot controls.

The standby batteries are only used when the standby battery switch is depressed and they are automatically recharged during the normal battery charging process.

OPERATION TABLE

5.3.2 Powered motions

WARNING

Always ensure that the patient is secure or adequately supported during all tabletop adjustments and that such adjustments do not compromise table stability.

If a patient is on the table and the handset is clipped onto the tabletop, take care that the handset buttons are not inadvertently activated (e.g. by a patient Transporter or person) causing unwanted table movements.

Similarly take care at all times to ensure that the handset is not inadvertently activated.

During all tabletop adjustments be aware of pinch points between the moving and static parts (e.g. the break hinge and head and leg hinges).

Ensure that all theatre drapes, electrical cords and any medical tubing etc. are clear from entrapment in pinch points and that adequate excess drape, cord, or tube, are available to cater for the adjustment required.

Ensure that any motion and adjustment selected will not cause any part of the table to hit or collide with any person or object. Examples being:-

i) Leg section hitting floor when table is

low and reverse Trendelenburg selected.

ii) A fully lowered leg section hitting table

base when tabletop is lowered.

iii) Head section hitting anaesthetist’s seat

when Trendelenburg selected.

CAUTION

Do not exceed the duty cycle for any motor drive as detailed in section 9.5.5.

5.3.2.1 General

The major tabletop adjustments and motions are powered. These powered motions are controlled by a corded handset supplied with the table (see 5.3.3) and the standby control panel (item 12, Fig. 2.2 see section 5.3.4). An optional infrared handset or an optional footswitch (see accessory list section 7.0) can also be used to control the tabletop. The use of these accessories is explained in the leaflet provided with them.

Powered tabletop motions are, Trendelenburg, height, tilt, brake, traverse, flexion and return to level. Each motion in either direction is controlled by pressing and holding the appropriate handset, footswitch or standby control panel button. The table must be switched ‘on’ for powered motions to operate. Section 5.3.3.2 details handset button functions, section 5.3.4 provides standby control panel information.

All signals from controllers will be treated in a strict priority order to avoid multiple activation errors from different controllers. Inputs will be responded to in the sequence below:

1 Standby control panel 2 Corded handset 3 Infrared handset 4 Footswitch control.

Button presses from a controller lower on this list will be ignored if any button is pressed on a controller higher on the list and the input from the higher controller will be actioned.

The table cannot be powered by footswitch, or either handset, when the main battery ‘critically low’ indication is displayed (see Fig. 10, main battery LED is ‘red’) unless the standby battery switch (item 1, Fig. 2.2 for T20-a and T20-s tables, or item 1, Fig. 2.3 for the T20-m table) is held depressed. However the tabletop can be controlled by the standby control panel (item 12, Fig. 2.2) situated on the side of the column. This standby control panel has limited functionality in comparison to either handset and should ONLY be used in an emergency (e.g. handset or footswitch failure, control system failure, or ‘critically low’ battery).

Use of this standby control panel in any situation other than an emergency SHOULD be avoided as certain safety devices are overridden. The controls and buttons of the standby control panel are detailed in section 5.3.4. In the unlikely event of insufficient battery power when using the standby control panel, press and hold the standby battery switch (item 1, Fig. 2.2 for T20-a and T20-s tables, or item 1, Fig. 2.3 for the T20-m table) whilst conducting powered motions.

In the unlikely event of failure of the main table batteries, ‘press and hold’ the standby battery switch (item 1, Fig. 2.2 or 2.3) in the ‘on’ position and use the corded or infrared handset or the standby control panel to control the table. This enables the standby batteries to power the table, however the main battery fault should be rectified as soon as possible.

T-IM114b P27/62

5.3.2.2 Tabletop motions

5.3.3 Using the handset

WARNING

Ensure you have read and understood the safety warnings listed in section 4.1 and 5.3.2 before using any of the powered motions.

All powered tabletop movements are programmed to provide a gentle transition from stationary into the required motion and back again to stationary (i.e. initially the motion starts slowly and then speeds up to maximum speed and then slows again before coming to a stop). This also enables accurate positioning at slow speed by using repeated short button presses. Alternatively long duration button presses allow large changes in tabletop position at maximum speed.

To operate the tabletop powered motions the table must be switched ‘on’ ( ) at the table on/off switch (item 5, Fig. 2.2). The table will emit a single ‘beep’ and the green LED (item 4, Fig. 2.2) will illuminate to show the table is ‘on’. The LED will be bright during use but only dim if the operating system has gone into ‘sleep’ mode (saving battery power). The table will instantly respond to any control input even when in ‘sleep’ mode. Also see section

8.1. If two buttons are pressed on a handset or footswitch at

the same time neither will have any effect. The function of the second button pressed is ignored and automatically cancels the function of the first button pressed and any table motion stops. Releasing either of the buttons will enable the function of the remaining button (if still pressed) to be actioned. This is to eliminate multiple button activation errors.

Most powered tabletop motions will pause briefly when they pass through the level position (Note: not applicable to height and traverse). This is to enable each motion to be returned to a level position individually.

Be aware that a lowered leg section could hit the table base when the top is lowered, or the head section could collide with an anaesthetist’s chair during a Trendelenburg movement.

5.3.3.1 General

WARNING

Do not plug two handsets into the table at the same time. When two handsets are connected, neither handset will operate the table.

The corded handset will operate any T20 operation table (note that the infrared handset is configured to match a specific table). Input from the corded handset will override any signals from an infrared handset. The corded handset simply plugs into either of the table handset sockets (item 3 of Fig. 2.2 and item 2, Fig. 5.11). Never plug handsets into both sockets at the same time. See section 5.3.3.2 for details of button function and section 5.3.1.1 for an explanation of the battery state LEDs.

When using the corded handset always ensure that the cord is well clear of any moving parts, pinch points and possible entrapment from table movements. Also ensure that the cord will cater for any table movement and that such table movements do not stretch the cord excessively.

When not in use it is suggested the handset is clipped onto the accessory side rail (item 7, Fig. 2.1). Note that when clipped onto the table in this way it can be operated with one finger, without the need to hold it in the other hand. The handset must be compatible with the side rail fitted to the table, see sections 1.1.2. The UK handset will also clip onto head/leg end blocks (item 9, Fig. 2.1).

To remove the handset plug from its socket the release button (item 1, Fig. 5.11) must be pressed and held in during removal. When removing the corded handset plug from its socket always grip and pull the plug, do not pull the cord only as this may damage the cord or internal connections.

Handset buttons provide a tactile feedback to enable the user to detect when a button has been pressed or released, this is in the form of a ‘pop’ or ‘click’. Also, all buttons are ‘de-bounced’ to ensure that only deliberate button presses are responded to (i.e. an accidental quick activation is ignored).

Always ensure that there is adequate space around the table for the movement selected and that the movement required will not cause injury to patient or medical personnel. Look for possible trap and or pinch points between parts of the table and stationary objects.

5.3.4 Using the standby control panel

WARNING

The standby control panel MUST be used with extreme care for Trendelenburg movements. All programmed safety features are overridden in this mode (e.g. should the tabletop hit an object, motor protection is inhibited and damage to them could occur). Also do not exceed 30° of Trendelenburg (or reverse) from the standby panel.

The standby control panel is located on the side of the column (item 12, Fig. 2.2). The panel has five function buttons (OB1 to OB5, see Fig. 5.13) and two direction buttons (OB6 and OB7, see Fig. 5.13). The motion of the function button is described by its graphical symbol (symbols are shown and detailed in section 2.2.4).

When controlling the tabletop from this standby control panel certain inbuilt safety features are overridden. Also there is no ‘soft start’ to the powered Trendelenburg movements and the tabletop will not pause as it passes through the level (Trendelenburg) position. Only five functions can be controlled from this panel Trendelenburg, Height, Tilt, Break and Traverse.

OB1 Trendelenburg - Press and hold this button, then

To operate the tabletop from this panel select a required function by ‘pressing and holding’ a function button (i.e. OB1 to OB5, Fig. 5.13) and then select a direction for this function by ‘pressing and holding’ a direction button (i.e. OB6 or OB7, Fig. 5.13).

Pressing the upper or lower direction button will select the direction indicated by the corresponding arrow on the function button. The table will move whilst both the function button and the direction button are pressed, releasing either will stop the motion. Motions for each button are fully detailed in the following sections.

These fuses are replaced as follows:-

i Remove the mains cord from the table before

replacing any of the fuses and switch the table ‘off’ with switch item 5, Fig. 2.2.

ii Turn the fuse cover cap anticlockwise to remove

the cap with the fuse inside.

iii Ensure you have the correct fuse (consult the

markings adjacent to the fuse or the Technical Data, section 9.0).

iv Place the new fuse into the cap and replace the cap

by screwing it in clockwise.

6.0 PATIENT POSITIONING

in various positions is shown in Figs. 6.3 and 6.4. For guidance on the treatment of the obese patient, see section 6.2.

6.1 General

WARNING

Do not use any table sections or accessories without the correct Eschmann mattress or pad in place (except for accessories such as the lightweight leg section which can be used for short periods of use, without a mattress, during patient positioning). Mattresses are an important part of the antistatic pathway and help prevent pressure sores developing.

Ensure the patient’s weight is evenly distributed and that the mattress or pad is correctly positioned on each section of the table. Check at frequent intervals during long procedures to ensure that pressure sores are not being promoted. See section 5.2.6 for details on attaching and removing mattresses.

Note the graphics in section 6.4 which provide maximum loading details for various table positions. The normal maximum loading, for the patient’s centre of gravity (C of G)

Fig. 6.1 Approximate patient weight

distributions

The Figures in section 6.4 provide details of various patient positions that can be arranged with the T20 Series of table. Note that these illustrations are examples only and care should be taken to ensure patient safety and table stability. The terms caudally and cranially are explained in section

1.2.1 (iv).

6.2 Treatment of the obese patient

Always ensure that the table is correctly loaded to maintain stability within the guidelines shown in the graphs of section

6.4 noting the maximum patient weight of 300kg. Note that the centre of gravity for the maximum patient weight of 300kg must not be outside of the top plateaux section of the graphs.

Several width extenders can be placed on either side of the table to help support the patient but note the maximum load for this accessory and that width extenders should not be attached to each other (also see Warnings and Cautions in the width extenders ‘User Handbook’ ).

The table should not be moved across the floor with a patient weight over 135kg (T20-a and T20-s tables) or 200kg (T20-m table). Although it is possible to place the T20-a and T20-s table into ‘castor’ or ‘wheel’ with a patient over 135kg and up to 300kg this is not advised.

6.3 Radiographic procedures

All ‘C-arm’ image intensifiers are suitable for use with this table.

Fig. 6.2 shows typical patient positions for imaging the upper and lower torso with the patient in the Supine position. The graphics would equally apply to patients in the Prone position.

6.4 Table positions and safe loading

In Figures 6.5 to 6.10, common table and patient positions and safe loading graphs are provided, to give guidance on patient positioning and table loading. Because it would not be possible to cover every situation these should be considered as examples only. Refer to Figs. 6.5 to 6.10 and then use Figs. 6.3 and 6.4 to establish the maximum patient weight allowed for that configuration. The weight of additional accessories fitted to the table should be included in any estimation of correctly applied loads.

Figs. 6.3 and 6.4 show graphs of the position of the maximum patient weights (centre of gravity) that can be positioned on the table in four table configurations. Because all variations can not be covered, a degree of interpolation is required by the user, to ensure that table stability is maintained. Fig. 6.1 provides an approximate patient weight distribution for guidance.

8.0 AFTER USE, CLEANING & CARE

8.1 After use procedures

CAUTION

Do not immerse the handsets or footswitch in liquids when cleaning or disinfecting.

After each procedure the table should be cleaned and disinfected in accordance with local procedures which take into account the guidelines provided in section 8.2 and 8.3 of this manual.

Accessories should be removed from the table and after cleaning and disinfection the head and leg section should be fully lowered as good practise.

The table battery LEDs should be checked to see if the batteries require recharging, recharge if applicable. If the preceding procedure was the last one for the day or shift, then the batteries should be placed on charge as a routine procedure (see section 5.3.1.2)

The table must be switched ‘off’ ( ) at the table on/off switch (item 5 of Fig. 2.2) when the table is not in use. The green LED item 4 Fig. 2.2 will not be illuminated to show the table is ‘off’.

If the table has been left switched ‘on’ and no movement command has been given via any controller (hand, foot or standby) for a period of six hours, an audible warning sounds (a slow repeating double ‘beep’). This is provided to warn

the user to switch the table ‘off’ ( ) at the table on/off switch (item 5 of Fig. 2.2). If the table is still in use when this alarm sounds (e.g. table being used for a long procedure) and the user does not want the table switched ‘off’ (e.g. Trendelenburg may be required urgently) the alarm can be stopped by pressing any control input briefly, or, switching the table ‘off’, waiting 10 seconds and then switching the table back ‘on’. The alarm will sound again in six hours if no movement command has been given and the table has not been switched ‘off’. This feature can be disabled or the time period of six hours can be altered, contact Eschmann Equipment for more information.

8.2 Cleaning

NOTE

Eschmann Equipment cannot accept liability for the efficiency or the effects of any cleaning or disinfection techniques. Only use the materials detailed in the following sections.

WARNING

Disconnect from the mains electrical supply before cleaning or disinfecting the operation table, mattresses, or accessories.

If you have any particular cleaning problems, contact the Eschmann Equipment After Sales Service Department at the address given inside the front cover of this Manual.

8.2.1 Operation table and accessories

Fully raise the tabletop, remove all accessories and all the mattresses, then wash the table with hot (55°C) neutral (pH7) detergent solution (diluted in accordance with the manufacturers instructions) and rinse with clean water. Use a small brush to clean areas of difficult access.

Clean non-electrical accessories as detailed above for the table but only use a damp cloth to clean the handsets and footswitch.

8.2.2 Mattresses and pads

WARNING

Mattresses and pads should be checked for any cuts or tears in the outer covering. If any of these defects are found, the mattress must be replaced to eliminate possible biological hazards.

CAUTION

Remove spilt ether and anaesthetic liquid from mattresses and pads immediately.

When cleaning mattresses and pads:

v DO NOT use phenolic disinfectants. v DO NOT use abrasive cleaning agents. v DO NOT use organic solvents (e.g. petroleum spirit,

carbon tetrachloride, or tetra-chloromethane).

v DO NOT allow petroleum-based oil, vegetable oil,

wax, or grease to remain on the mattress.

v DO NOT dry mattresses with direct heat (e.g.

radiators, electric fires, or hot-air blowers) allow them to dry at normal room temperatures.

Wash mattresses and pads thoroughly, with hot (55°C) neutral (pH7) detergent solution (diluted in accordance with the manufacturers instructions) and then rinse with clean water. Use a small brush to clean areas of limited access. Remove stubborn stains and deposits with good quality vinyl cleaner using a soft-bristle brush. Dry all surfaces with absorbent paper, to avoid damage do not leave them wet in contact with another surface (e.g. the table top).

8.3 Disinfection

NOTE

All equipment and accessories returned to Eschmann Equipment must be accompanied by a Decontamination Certificate, signed by an authorized person of managerial status. Appendix 2 shows an example of a suitable Decontamination Certificate that can be photocopied for use.

CAUTION

Hypochlorite solutions can damage metal parts, after disinfection, ensure it is rinsed of thoroughly with water. Prolonged exposure to hypochlorite solutions may degrade mattress material. Avoid hypochlorite solutions and other liquids coming into contact with any internal parts of the table.

8.3.1 Disinfection procedure

A well ventilated area should be designated and used as the disinfection area. Access to the area should be restricted to those people involved in the disinfection process.

The following disinfection procedure is used by Eschmann Equipment, and its use is recommended if no other local approved procedures are available.

8.3.2 Table, accessories mattresses and pads

Disinfect the operation table, accessories, mattresses and pads as follows:

i Disassemble the table and/or accessories as far

as possible without the use of tools, remove mattresses and pads.

ii Scrub all surfaces and crevices with hot (55°C)

neutral (pH7) detergent solution (diluted in accordance with the manufacturers instructions) to remove all visible contamination. Use a small brush to clean areas of limited access repositioning the table as required to gain access to all surfaces. For

stubborn mattress stains see section 8.2.2. iii Wash down with hot (55°C) water. iv Dry all surfaces with absorbent paper. v Wash down all surfaces and crevices with one of

the solutions below:

vi Dry all surfaces with absorbent paper, to avoid

damage do not leave mattresses wet in contact with another surface.

vii Dispose of all cleaning material and solutions in

accordance with authorized disposal procedures.

8.4 Care

WARNING

The head and leg section gas-springs are filled with gas at high pressure, do not try to open them. The gas-springs should be replaced immediately any signs of leaking or deterioration in performance are noted (e.g. movement of section when locked).

CAUTION

Do not lubricate the head or the

leg section, gas-springs.

Once a week:

i Remove fluff and debris from the head and leg

section guide pin location sockets and if required spray the pins and into the sockets with a suitable light lubricant such as WD40.

ii Remove all mattresses and check them for any cuts,

scuffs or other damage and replace as required.

9.5.5 Duty cycle

This symbol is used to indicate the table’s duty cycle

which, in the worst case, is ‘60s : 600s’, the ratio of the operating time to the sum of the operating time and the ensuing interval (see note below). Each motor drive has its own duty cycle and this is dependent on loading and table position as detailed below.

Trendelenburg 1 : 4 (60s : 240s) at a maximum torque

of 417Nm (e.g. 135kg load offset 31cm from the fulcrum, or a 300kg load offset 14cm from the fulcrum. Where this load is the patient and accessories weight and the offset is how far the loads centre of gravity is, from the centre of the column).

Traverse 1 : 4 (60s : 240s) when the table is horizontal

and at the maximum load of 300kg, or at 17.5° with a patient weight of 225kg, or at 35° with a patient weight of 150kg.

9.7.1 Electrosurgical equipment (h.f.)

The T20 Series of operation table have been designed to minimise the possibility of accidental electrosurgery burns and can be used in conjunction with electrosurgical equipment. However contact with any metal surfaces (e.g. table side rail, or other equipment etc.) can cause burns during electrosurgery and must be avoided.

9.10.2 Audible

Audible alarm indication is provided (a double ‘beep’ repeating every eight seconds) to warn that the table has been left ‘on’ for an extended period and should be switched ‘off’ (see section 8.1 for more information). A single ‘beep’ also sounds when the table is switched ‘on’.

9.11 Electromagnetic compatibility (EMC)

9.11.1 Interference considerations

The Eschmann T20 Series of tables have been designed and manufactured in such a way as to remove, or minimise as far as possible, risks connected with reasonably foreseeable environmental conditions such as magnetic fields and external electrical influences (i.e. electrical interference). The risks of electrical interference from or to other devices normally used with these tables have been taken into account. The steps taken to achieve this are to ensure compliance with relevant international electromedical standards {i.e. EN 60601-1-2:2001) regarding electromagnetic compatibility. This compliance has been confirmed by independent testing. However it is not possible to simulate all the conditions that may be encountered, the compliance testing therefore provides only a very good indication as to the susceptibility or suppression of emissions to or from a device. It is highly unlikely that any electrical interference problems will be encountered with these tables. However, should such interference be suspected, the following the following guidance is provided.

9.11.2 Interference from other equipment

The Eschmann T20 Series of tables have been designed to ensure that when using them in close proximity with ‘other correctly designed’ electrical equipment, interference with the tables control systems does not occur. Eschmann cannot guarantee that other equipment used in an operating theatre is properly constructed so as to avoid electrical interference with them. This could be a problem particularly with very old equipment (i.e. it does not conform to the latest standards). In the unlikely event that electromagnetic interference is caused by ‘other’ noncompliant equipment, such ‘other’ equipment should not be activated at the same time these tables are switched ‘on’ and their control systems are active.

these tables, the other equipment should not be activated at the same time as the tables are switched ‘on’ and their control systems are active.

9.11.4 RF communications equipment

As with all medical electrical equipment the user should be aware that portable and mobile RF communications equipment can affect medical electrical equipment such as these tables.

9.11.5 Accessories

As with all medical electrical equipment, and in line with the latest European standard (EN 60606-1-2:2001) the user should be warned that the use of accessories, transducers and cables other than those specified below (with the exception of those sold by Eschmann Equipment as replacement parts for internal components) may result in increased emissions or decreased immunity of the these tables and their associated accessories.

The following Eschmann Equipment accessories can be used with these tables without affecting the table’s electromagnetic compatibility with subclauses 36.201 and

36.202 of EN60601-1-2:2001. Other similar accessories or equivalents that could affect compliance with the requirements of subclauses 36.201 and 36.202 of EN60601-1-2:2001 should not be used.

Mains cord (for part number see section 7.0). T00-5300001 Handset, blue, (UK side rail) T00-5400001 Handset, purple, (UK side rail) (also, other handsets for non UK side rail)

All the other accessories listed in section 7.0 are designed for use with the Eschmann T20 Series of tables and have no EMC implications.

9.11.6 Installation

WARNING

The T20 Series tables should not be stacked with other equipment. If used adjacent to other equipment these tables should be observed to verify normal operation in the configuration in which it will be used.

9.11.3 Interference with other equipment

The Eschmann T20 Series of tables have been designed to ensure that when used in close proximity with other correctly designed equipment they do not cause interference with such other correctly designed equipment. Eschmann cannot guarantee that other equipment used in an operating theatre is properly constructed to withstand electrical interference with adjacent equipment. This could be a problem particularly with very old equipment (i.e. it does not conform to the latest standards). In the unlikely event that electromagnetic interference is experienced with

The Eschmann T20 Series of tables have been tested for use in close proximity with other equipment and should be installed in accordance with the EMC tables that follow in section 9.11.7.

9.11.7 EMC tables

The following guidance (in table format) is provided in line with EN60601-1-2:2001. The table references (i.e. 201, 202, etc.) are those used within the standard. All other tables referenced within the standard do not apply to the T20 Series of table.

BATTERY MANAGEMENT SHEET FOR THE ESCHMANN T20 OPERATION TABLE

CAUTION

Continued use of the table batteries in the ‘critically low’ state can damage the batteries.

Batteries within the table base are mains rechargeable, to maintain peak battery performance the table batteries should be placed ‘on charge’ at the end of each day or shift, do not wait a ‘low’ battery indication, it is good practice to charge daily. Batteries must be charged at the end of the shift when a ‘low’ indication is given and as soon as possible when a ‘critically low’ indication is given.

Batteries should be checked for adequate charge before using the table for any surgical procedure. The orange battery LEDs on the corded handset indicate a ‘low’ battery and the red LEDs indicate a ‘critically low battery’. When the ‘critically low’ battery warning is indicated the table cannot be operated by either of the handsets or the footswitch. To continue to operate the table either connect it to a suitable mains supply and recharge the batteries, or use the standby batteries or control panel. To use the standby batteries the standby battery switch must be pressed and held depressed whilst the required motions are conducted using the normal controls.

To recharge the table batteries (normal and standby) connect the mains cord supplied (do not use any other cord) into the mains inlet. Connect the mains cord to a suitable mains supply (check voltage) and switch the supply ‘on’ if controlled by a switch. The battery charging LEDs will illuminate ‘red’ to indicate ‘bulk’ recharge, ‘amber’ to indicate ‘top-up’ charge and ‘green’ to indicate a fully charged battery on ‘trickle’ charge. Note: The standby control panel can be used even when the ‘critically low’ battery indication is given but note the warning given in section 4.6.5 of the ‘Instructions for Use’.

MANUAL HANDLING SAFETY NOTES AND ADVICE

Series

1 Manual handling

1.1 During configuration or adjustment of the T20 series of table there are occasions where the user should be aware of the safe practises to be employed during manual handling or adjustment of parts of the table. For information the weights of the heaviest accessories commonly used are listed below. When lifting, carrying or fitting these accessories it is recommended that care is taken and two people are employed when required.

Leg section, without mattress, 11.50kg (25.3lb) Leg section, with 50mm mattress, 14.25kg (31.4lb) Leg section, with 75mm mattress, 15.63kg (34.4lb) Head section, without mattress, 7.75kg (17.1lb) Head section, with 50mm mattress, 9.75kg (21.5lb) Head section, with 75mm mattress, 10.75kg (23.7lb) Long and short trunk 50mm mattress, 7.25kg (16.0lb) Long and short trunk 75mm mattress 10.88kg (23.9lb) Footrest, without mattress, 5.00kg (11.0lb) Footrest, including 50mm mattress, 7.00kg (15.4lb) A divided leg section, 7.70kg (16.9lb) A divided leg section, with 50mm mattress, 9.90kg (21.8lb) A divided leg section, with 75mm mattress, 11.0kg (24.2lb) Long width extender, with 75mm mattress, 6.00kg (13.2lb)

* NOTE: 50mm mattress weights included in the values above are for the original style of 50mm mattress. The latest 50mm mattress weights are approximately one third of those indicated above. New mattresses can be identified by the white breather ports on their base (see section 7.0).

1.2 When adjusting a section such as the head and leg section the weight is partially supported* by the gas springs, but together with the weight of the patient’s limbs, the total weight required to be lifted could be much greater than the weight of the section and mattress*. It is not possible to quantify this weight exactly as each situation will vary, but Fig. 4.9 should assist in an approximation, taking into account the patient’s actual total weight.

These ‘Instructions for use’ advise supporting the weight of the patient during adjustment of any section, obviously this requires the intervention of several personnel, some supporting the patient’s limbs and others adjusting the table sections.

* Because of the complexities involved in both the way the patient loading acts on a section, and the assisting force provided by the gas spring varies, as the section is raised or lowered about its hinge, the load at a particular point cannot be exactly stated.

1.3 Manual handling is covered by legislation and the Manual Handling Operations Regulations 1992 require employers to avoid the need for employees to carry out

manual handling work that could cause injury by mechanising processes, or reorganising work, so far as is reasonably practicable. It states that it is the Duty of Employees while at work to make full and proper use of any system of work provided for his use by his employer to comply with these regulations. To this end the following publication could be used to create such a system of working, “Manual Handling in the health services”, Health and Safety Commission, 1998.

1.4 There are no recommended maximum weights specified in the “Manual Handling Operations Regulations 1992” or the “Health and Safety (miscellaneous amendment) Regulations 2002” but the notes following may be considered useful in compiling a safe working practice. The reason no specific maximum weights are stipulated is that factors such as an individuals capabilities (height, gender, strength, etc.) the load (size, availability of handholds, weight, etc.) the task (motion required, duration, distance, etc.) the environment and other factors all need to be assessed when considering the task.

2 How to lift safely

Where the ‘load’ is a patient the person or team must communicate with the patient throughout the lifting procedure if they are conscious. Here are some important points, using a basic lifting operation as an example, these points can be remembered as the four ‘Ps’.

i PLAN - Plan the lift.

Where is the load to be placed? Use appropriate handling aids if possible. Do you need help with the load? Remove obstructions such as discarded wrapping materials. For a long lift, such as floor-toshoulder height, consider resting the load midway on a table or bench in order to change grip.

ii PREPARE - Prepare load and position feet.

Make the load secure, easy to hold, safe and compact. Clear obstructions and any floor hazards giving good visibility and space. Position the feet apart, giving a balanced and stable base for lifting with the leading leg as far forward as is comfortable.

iii POSTURE - Adopt a good posture.

When lifting from a low level, bend the knees. But do not kneel or overflex the knees. Keep the back straight (tucking in the chin helps). Lean forward a little over the load if necessary to get a good grip. Get as close to the load as possible. Keep the shoulders level and facing in the same direction as the hips. Try to keep the arms within the boundary formed by the legs, elbows tucked in. The best

T-IM114b P61/62

position and type of grip depends on the circumstances and individual preference; but it must be secure. A hook grip is less tiring than keeping the fingers straight. If you need to vary the grip as the lift progresses, do it as smoothly as possible.

iv PERFORM - Keep close to the load.

Keep the load close to your trunk for as long as possible. Keep the heaviest side of the load next to your trunk. If a close approach to the load is not possible, slide it towards you before trying to lift. Lift smoothly, keeping control of the load. Don’t twist the trunk when turning to the side.

3 Team lifting

Never be pushed into lifting with others if you are unsure about their knowledge or ability. Say NO. The key factors involved in team lifting are the three 'Cs':

i Communication

There must be a team leader to direct the procedure. The leader should give a command to lift or move, first making sure that every member of the team understands the command to be used. The leader must be in control of the procedure from start to finish.

ii Cooperation

The team must lift together. It helps if the team members are similar in height and build (but this is not essential). The team needs to have trust and confidence in each other. If one member of a team fails to lift or move properly it is probable that someone will be injured.

iii Coordination

The team members must communicate, if only by a nod of the head. They must indicate when they are ready. If they are tiring or need a break, telling other members in sufficient time to allow the load to be lowered safely, before they drop it, is important.
