1.2 About this manual

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

i)

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.

T-IM114b P13/62

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

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.

accessories that are compatible with the T20 Series
of table as detailed in these instructions.

♦ Check that handset cables and standby controls are

not damaged before use.

♦ Check that the table and its accessories are not worn

or damaged, or are in any way not suitable for the
intended purpose, before use.

♦ 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.

T-IM114b P17/62

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.

T20

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.

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’.
