1 Preface and general instructions
The various bed systems from Hermann Bock meet special requirements for the use in
care and treatment facilities as well as for home care. Reliable functionality and a long
product life make each bed particularly valuable. Our beds need little maintenance with
proper operation and care. Each bed from Hermann Bock must pass quality testing in a
final inspection before it is shipped anywhere. The beds are manufactured according to
the current standards and compliant with the statutory requirements for medically used
beds, and tested accordingly.
The nursing care beds comply with the EN 60601-2-52 standard. The electrical building
components comply with safety standard EN 60601-1 for medical devices. Nursing care
beds are medical devices and are to be assigned to Class 1.
These standards divide the beds in five different areas of use:
1. Intensive care in a hospital; intensive care bed
2. Short-term care in a hospital or other medical facility; patient bed in the hospital
3. Long-term care in medical environment; stationary nursing care bed
4. Care at home, pure so-called “HomeCare bed”
5. Home-care nursing service
1.1 Intended purpose
The nursing care bed is suitable for persons (adults) in need of
care who are at least 146 cm tall. The person's weight must not
exceed 185 kg and must be over 40 kg. The body mass index
(BMI = weight of the person (kg) / body height of the person (m)2)
must be greater than or equal to 17.
The nursing care bed may be used in homes for the elderly or nursing homes and rehabilitation facilities. It is used to alleviate a disability and/or to facilitate the lives of people
who are in need of care or to make the work of their caregivers easier. Furthermore, the
nursing care bed was also designed as a convenient solution for the home care of frail and
elderly people as well as for home care of people with disabilities. Accordingly, the nursing
care beds are designed to be used for the application environments 3 to 5. Any other use
is considered improper and is excluded from a possible liability claim.
The Trendelenburg function may be used exclusively under supervision of medical professionals. The beds, which are determined for application environment type 4, are equipped
with a hand control which is unable to operate the Trendelenburg function.
5
The nursing care bed is not suitable for use in hospitals. If the nursing care bed is equipped
with open wheels, the nursing care bed is suitable for the transport of patients. The nursing care bed is mobile with the patient resting in it. To prepare for this, lock the castors
and move the lying surface to the lowest horizontal position. Unlock the castors and move
the bed. After the transport, lock the castors. If the nursing care bed is equipped with a
roller cover, the bed is only suitable to be moved for cleaning purposes inside the patient’s
room or to allow access to the patient.
The bed is suitable for the re-use. Please observe the instructions for cleaning, care and
disinfection in these assembly and operation manual. Special attention must also be paid
to the information regarding the inspections.
Attention: The beds come with no special connection options for a potential equalisation.
Electrical medical devices connected to the patient intravascular or intracardiac may not
be used. The operator of the medical products has to ensure that the combination of the
equipment meets the requirements of EN 60601-1.
This user manual contains safety instructions. All persons working with the beds must
be acquainted with the contents of these instructions. Improper operation can result in
personal injuries.
1.2 Definition of person groups
Operator
Operators (e.g. medical supply stores, specialist dealers, facilities and cost units) include
all physical or juridical persons, who use the beds or have the beds used for medical purposes. The briefing on the use of the product shall generally be conducted by the operator.
User
Users are persons whose training, experience or briefing on the product allows them to
operate the nursing care bed or carry out works on it. The user is able to recognize possible
hazards and/or to avoid them and to assess the health condition of the patient.
Patient/resident
Person with one or more disabilities, one or more activity restrictions, one or more participation restrictions or a combination thereof.
Qualified personnel
Employees of the operator are referred to as qualified personnel. They are entitled to
deliver the nursing care bed, assemble, dismantle and transport it, on the basis of their
training or instructions. Besides knowing how to operate, mount and demount the nursing
care bed, these persons must be instructed according to the guidelines concerning the
cleaning and disinfection of the nursing care bed.

1.3 Safety instructions
The intended use/operation of all moving parts is as important for the safety of the person
in need of care as well as for the relatives and the caregivers/nursing staff to avoid potentially dangerous situations. This requires the correct installation and operation of the bed.
The individual physique of the person in need of care as well as type and the extent of
their disability must be taken into account by all means when operating the bed.
Avoid dangers, accidental motor adjustments and incorrect operation by using the disabling function. When the operator, e.g. the nursing staff/caregivers or the care providing
relative leaves the room, the entire operating functions of the bed should be disabled via
the hand control. This is achieved by operating the key of the hand control. First, lower
the lying surface to the lowest position and activate the lock function with a twist of the
key, located in the key lock on the backside. Remove the key and check the function of
the hand control for safety reasons. Make sure that it is indeed locked.
These recommendations apply particularly:
– if the person in need of care cannot operate the hand control safely due to
certain disabilities;
– if the person in need of care or the caregivers could be at risk due to those
accidental adjustments;
– if the side rails are in a raised position and there could be danger of trapping
and crushing,
– if children are unsupervised in the room with the bed.
Always make sure that the hand control (when not in use) is securely hooked in the support hook at the bed and cannot drop.
As a general rule, the bed should be operated by instructed nursing staff/caregivers, relatives or in attendance of instructed persons.
When adjusting the lying surface, it is particularly important to ensure that no limbs are
placed within the adjustment range of the side rails. If the side rails are adjusted, pay
attention to the correct lying position of the person in need of care.
Prior to making any electrical adjustment, it should, as a general rule, be made sure that
no limbs are positioned in the adjustment range between the chassis and the head or foot
part, especially that there are no persons or animals in the area between the floor and the
raised lying surface. Danger of being crushed is particularly high in these areas. Always
beware of objects that are located close to or even below the nursing care bed. This can
lead to damages.

The permitted person’s weight depends on the total weight of the equipment that has
been mounted to the bed (mattresses and other electronic medical devices). For safe
working load, please refer to the type plate on the lying surface frame of the bed.
1.4 Service life / warranty
This nursing care bed was developed, designed and manufactured for safe operation over
a long period of time. With proper operation and maintenance, this nursing care bed has
an expected service life of 15 to 20 years. The service life depends on operating conditions
and frequency.
Attention: Unauthorised technical changes to the product voids all warranty claims.
This product is not approved for the North American market, particularly not for the
United States of America (USA). Distribution and use of the nursing care bed in these
markets, including through third parties, is prohibited by the manufacturer.
1.5 Requirements for the installation location
The company Hermann Bock GmbH is not liable for damages which might arise from the
daily usage on the floor.
To avoid floor indentations, floor should correspond to the recommendations of the FEB
- Fachverband der Hersteller elastischer Bodenbeläge e.V. (Association of Elastic Floor
Coverings Manufacturers). To do this, the technical information FEB No. 3 can be referenced.
Hazard note from Bock
Simultaneous use of electrical appliances particularly in the vicinity of the operational bed may
result in small electromagnetic interactions of these electric devices, e.g. static noise in the radio. In such rare events, increase the distance of the devices. Do not use the same socket or
temporarily switch off the interference source and/or the disturbing or disturbed device.
If the bed should be operated with electrical medical equipment (contrary to its intended use),
the functions of the bed must first be disabled via the integrated locking function in the hand
control for the duration of the application.

2 General description of the functions
Construction design and function
Corrosion protection
The Hermann Bock GmbH nursing care beds are developed and constructed in such a way
that they can function long and safely. For this reason, all materials that may corrode are
protected accordingly. All metal parts are equipped with a surface protection. The steel
parts are either galvanised or stove-enamelled with a PES powder coating and the aluminium profiles are anodised.
The lying surface with 4 function areas
The lying surface consists as standard of a slatted comfort frame (can alternatively be fitted with aluminium slats or special suspension systems) and is divided into four functional
areas: Backrest, fixed seat part, upper and lower leg rest.
The comprehensive
lying surface frame
is welded from a
steel / aluminium
tube. The steel
tubes are stoveenamelled with a
PES-powder coating. The electric
variable height adjustment of the lying surface is carried out with protective
low-voltage DC motors (29 to 35V), and controlled with the smooth keys of the hand controller. The backrest can be adjusted electrically. The leg part consists of a foot support
that is divided into two parts. With a touch of a button on the hand control, each individual
position can be adjusted continuously. In case of a power failure the back part that can be
lowered by loosening the tube clip.
The chassis
The height adjustment of the bed is performed through a base frame with two individual
drives. The surface of the tubular steel structure is stove-enamelled with a PES-powder
coating.
The side rail
Each nursing care bed can be equipped on both sides with two side rails at a special safety
height. The side rails can be lifted and lowered through a rail. The sliding pieces run particularly smoothly and quietly with an impact damper, and each end is fitted with a functional cap. The side rail can be easily operated through an ergonomically designed release

button. Depending on the model, shorter or longer divided side rail variations are available.
Operating the telescopic divided side rails
Each side rail element can be adjusted independently from the rest
of the side rail parts. The release buttons for adjustment are on the
bottom of the telescopic post and on the top of the appropriate end
panel of the nursing care beds, right next to the metal guides for the
side guard rail bars.
To lower the side rail element, hold the upper knob (1) of the middle
post with one hand, lift it up slightly, and with the other hand press
the release button (2) on the middle post in the inner direction.
The side rail opens at the corresponding place and can be easily lowered downwards as far as it will go (3). The side rail is now diagonal.
To also lower the other side, please hold the side rail on the side of
the end panel at the gripping groove (4), and slowly raise the side
rail somewhat. Now, you can fully press the release button (5) and
slowly lower the side rail.
Please observe:
Be sure to raise the side rail slightly, and only then press
the release button! Failure to do so will result in damage to the release.
The side rail is now in the lowered position.
If the side rail element should be placed in the top position to aid in
fall prevention, reach with both hands in the centre of the gripping
groove (6) in the upper side guard rail, and pull it upwards until you
hear it click into place at both ends. The side rail is now in a pulledup position.

Hazard note from Bock
Use only original Bock side rails, which are available as accessories for every nursing care beds.
Use only technically flawless and non-damaged side rails with the permissible gap dimensions.
Make sure that the side rails are engaged securely.
Before installation of the side rail and each new use, inspect all mechanical parts on the bed
frame, and all parts of the side rails, and all parts which secure the side rails, for any possible
damages.
The operation of the side rail should be done with great care. Fingers can be quickly pinched
between the longitudinal pieces.

3 Electric parts
3.1 The drive unit
The drive unit consists of individual drives for the electrical adjustment of the back and
leg rest part. The level adjustment is performed with two individual drives that are attached to the chassis. The adjustment range of these individual drives is determined via
Hall sensors. The motors and the hand control are connected to the inner control box. A
power supply converts the input voltage into a low voltage power of max. 29 VDC (direct
current). The motors, controller and the hand control function with this non-hazardous
low protective voltage. The cables are double-insulated and the mains plug has a primary
fuse.
A power adjustment provides constant function speed. Therefore, the safety functions
comply with protection class II and the moisture barrier protection type IPX4.
The maximum duty cycle is specified on the (type plate) of the bed. For example, 10% duty
cycle (2 min. ON / 18 min. OFF) means that any electronic adjustment can be performed
for a max. of 2 minutes within a timeframe of 20 minutes (protection against overheating).
If the maximum setting time of two minutes is exceeded by two minutes (e.g. someone
plays continuously with the hand control), which could lead to overheating of the controller or drives, the thermal fuse immediately shuts off the power supply to the bed. After a
cooling time of approx. one hour, the power supply in the controller is automatically restored.
3.2 Caution: Electric drive
The electrically operated nursing care bed enables the person in need of care to support
the recovery process psychologically and physically and at the same time relieve pain
through its various functions. Electrically operated beds that are medical products need
special care in regards to constant safety checks. This includes safety-conscious handling
of the bed, daily inspection of electrical equipment and proper maintenance and cleaning.
To prevent damages to the cables, wiring should be conducted outside of the area in
which damages could be caused. Furthermore, avoid touching the sharp parts. To prevent
injury through an electric shock, avoid the possibilities of too high contact voltages. These
circumstances may especially be the case if the power cable is damaged, if inadmissible
and excessive leakage currents exist, or if liquid was spilled into the motor housing, e.g.
during improper cleaning. This damage can cause malfunction of the controller, which
could result in unwanted movements of single bed elements, posing a risk of injury for the
operator and the person in need of care.
15
3.3 Drives
Hermann Bock GmbH equips nursing care beds with drive systems from the company
DewertOkin GmbH.
Each drive consists always of four main components.
– Housing
– Motor
– Gear
- Spindle with nut
The housing principle of the individual drive guarantees the permanent function of all
drive components. Through a detailed interior structure, the construction of the housing
interior creates an essential prerequisite for the precise integration of the drive technology, as well as a trouble-free assembly/disassembly.
3.4 The external switch mode power supply SMPS
The plug-in part of the external switch mode power supply (SMPS) is an electronic transformer, which warms up only to a minimum degree under load and it is equipped with
electronic performance monitoring. The result is a constant voltage up to the maximum
load (no loss of speed) and a high level of protection against overloading. The external
transformer ensures safety right from the socket because it converts the voltage directly
into the 29V safety low-voltage which is used to actuate the bed. It is connected via plug
coupling to the mains supply line feeder cable and can be replaced separately if defective.
The plug-in part of the external switch mode power supply complies with the European
directives for electrical household appliances. In standby mode, it also has a low energy
consumption of maximum 0.5 Watt and can be used internationally with variable input
voltages from 100 V to 240 V. Electromagnetic alternating fields are not measurable on
the SMPS adapter.
The external switch mode power supply

3.5 The controller
Practico alu plus controller
The practico alu plus is equipped with a controller system from DewertOkin GmbH. Four
drives can be connected to the controller (sockets 3,4,5 and 6). The colour coding can be
found in chapter 4 "Assembly and operation". Additionally, a floor lighting can be connected to the connection socket for the hand control (socket 2). Please make sure that a
dummy plug is attached to the connector for the battery (socket 7) if no battery is connected. A jumper plug must be fitted to the connection for the additional control element
(socket 1). The pigtail connector (not in Fig.), which is the cable that is run from the top of
the controller, can be used to connect a reading lamp.
Practico alu SCC controller
The practico alu SCC is equipped with a controller system from Hermann Bock GmbH. The
socket 1 is a CAN-BUS connection which can also be used to connect a sensor pad for bedoff detection. Further details can be found in the separately supplied assembly and operation manual of the Smart-Care-Control unit. A Y-cable is plugged into the socket 2, which
is used to connect the floor lighting and the reading lamp. The supplied hand control must
be connected to socket 3. The connector sockets 4, 5, 6 and 7 are intended for the individual drives in the scissor and lying surface.
17
3.6 The series hand control
The series hand control is equipped with a built-in locking device, which allows the caregivers to lock the hand switch via a key completely or partially for its operation.
The lockable hand control, first-fault protected
The base functions can be controlled through the ten operation keys on the hand control.
The four symbols in the middle indicate a special function that can be performed by simultaneously pressing the adjacent keys. The individual keys are marked with corresponding symbols. The servomotors run until as long as a corresponding key is pressed and held.
A coiled cable allows the necessary freedom of movement while operating.
With the rear-mounted suspension unit, the hand control can be attached to the side rail
- particularly when cleaning and during the maintenance of the bed. Thus, a possible disruptive position of the hand control can be avoided by simply attaching it to any preferred
spot on the bed.
Hazard note from Bock
All drive components must not be opened!
Troubleshooting or exchanging single electrical components may only be performed only by
special qualified personnel.
Hazard note from Bock
The motors meet the water protection standard IPX4. Do not squeeze/crush the cables. Adjustment of moving parts may only be used for the intended use. Hermann Bock GmbH assumes no
liability for unauthorized technical changes.
Hazard note by Bock
Do not try to fix failures on the electrical equipment itself. It could be fatal! Either call the customer service of Hermann Bock GmbH or an authorised/licensed electrician who conducts the
troubleshooting in compliance with all relevant VDE regulations and safety regulations.

3.10 Rechargeable Battery (optional as accessory)
The battery serves as a mains-independent reset function. No warranty shall be provided
for the functioning of the drive in the event of a power failure.
Fully charge the battery for at least 24 hours before the first use. The built-in rechargeable
batteries only reach their full capacity after 5 to 10 charging and discharging cycles.
As long as the controller is supplied with mains voltage, the automatic charging circuit
ensures a permanent operational readiness. After using the drive system independently
from the mains power, the battery should be recharged immediately by re-establishing
the mains connection.
When the battery voltage reaches the cut-off threshold, the drive system is completely
deactivated. The deep discharge protection protects the battery from possible damages
that could result from failure to observe the discharge warning. If the voltage of the battery reaches the threshold of the deep discharge protection warning during driving, an
acoustic signal sound. The battery should be

Hazard note from Bock
Note the idle time of the battery. This must rest for at least one hour prior to commissioning,
removal and replacement of the battery.
There is a danger of electric shock! Before mounting, be sure to disconnect the mains plug of
the drive from the socket! Make sure that the mains plug is accessible at all times.
To increase operational safety, carry out the following measures before initial commissioning
or after extreme mechanical loads: Check the housing for damages. If the housing show signs of
damage, or if the unit heats up excessively: Then disconnect the battery from the controller and
shut down the drive system.
Do not open or destroy the battery.
Do not expose the battery to heat or open fire. Avoid storage in direct sunlight.
If the battery is leaking and there is a contact with the leaking liquid, rinse the liquid off thoroughly with water and seek medical attention immediately.
Dispose of the battery in accordance with the legal regulations for used batteries and rechargeable batteries,
as these may not be disposed of with household waste.
Maintenance: Perform regular visual inspections (at least every 6 months). Pay attention to possible damages on the housing, and check the plug connections and the cables for damages,
crushed sections or shearing.
Maximum storage time 6 is months at the recommended storage temperature. Afterwards, the
battery should be
charged again. At higher storage temperatures, the battery should be charged at an earlier
point in time. This is to avoid a deep discharge, which could lead to an irreparable damage
of the battery.
Hazard note from Bock
Bed models with roller covers are not suitable for the transportation of the patient. The beds
must be only moved for cleaning purposes inside the patient’s room or to allow access to the
patient.

4.2 practico alu plus and practico alu SCC
A bed for all circumstances that unifies technology and comfort. Technically perfected
down to the last detail: The practico alu plus and the practico alu SCC can be extended
without any tools, and therefore individually adapted to patients. It is really easy: The fully
ergonomic, real bed extension is inserted in the blink of an eye, as described at the end of
this chapter. The side rails are provided for all lengths. These nursing care beds provide a
high degree of comfort to frail people, patients who need care and people with disabilities,
thus facilitating an optimal care through a high lying comfort and an easy operation.
- practico alu plus and practico alu SCC are not intended to be used in hospitals.
- If the practico alu plus or practico alu SCC are equipped with open wheels, the
nursing care bed is suitable for the transport of patients. The bed is mobile with
the patient resting in it. To prepare for this, lock the castors and move the lying
surface to the lowest horizontal position. Unlock the castors and move the bed.
After the transport, lock the castors. If the nursing care bed is equipped with a
roller cover, the bed is only suitable to be moved for cleaning purposes inside the
patient’s room or to allow access to the patient.
- The nursing care bed is suitable for persons (adults) in need of care who are at
least 146 cm tall. The person's weight must not exceed 185 kg and must be over
40 kg. The body mass index (BMI) must be greater than or equal to 17.
- Under certain circumstances the practico alu plus or practico alu SCC can be used
(if necessary) for medical purposes with other electric medical equipment (e.g.
suction devices, ultrasonic humidifiers, food systems, anti-bedsore systems, oxygen concentrators and similar devices). In this event, disable all bed functions for
the duration of the application via the integrated disabling function.
Attention: The bed has no special connection options for a potential equalisation. Electrical medical devices connected to the patient intravascular or intracardiac may not be
used. The operator of the medical products has to ensure that the combination of the
equipment meets the requirements of EN 60601-1.
25
practico alu plus and practico alu SCC preparation for operation
Remove all packaging from the bed and
place chassis on a free and flat surface.
Place the lying surface on top of the chassis.
Pay attention to the head and leg end.
This Fig. shows the central locking foot pedal
on the left side of the chassis, which must be
located on the foot end of the lying surface.
Slide the lying surface on the chassis so that
the holes are aligned on top of each other.
Attach the lying surface using the 4 screws
provided (cylinder head screws M8x45) and
the 4 nuts.
Now, route the lying surface motor cables and the cable of the hand control safely below
the lying surface up to the control box. Ensure that the cables cannot be not clamped or
damaged in any way. To simplify the cable routing, you can remove some of the panels from
the lying surface frame.
26
Attention: The following note only applies to the alu practico plus: If your bed is factoryequipped with an floor lighting, you must insert the hand control into the free socket of one
of the two floor lighting units. The floor lighting is already mounted on the lying surface
frame. In this case, the plug of the floor lighting must be inserted into the socket for the
hand control (red mark) on the controller. Ensure that all sockets are subsequently covered
with the locking caps, in order to guarantee the protection class requirements.
Cable routing from the head part motor to
the controller.
Please use the clip to attach the cable centred on the head lifter part.

Please note the descriptions of the controllers in Chapter 3.
After all plugs have been connected to the
controller, you can clip the supplied cover
cap on the controller so that the connectors
are securely fastened.
Route the power cable in the middle across
the frame of the undercarriage, all the way
to the head end piece. There, please screw
on the cable with the help of the strain relief.
IMPORTANT!
Please perform a reset of all the motors,
before putting the bed into operation.
This process is described in Chapter 3 on
page 18.
28
If the mounting latches for the end panels
are not yet mounted, slide them into the longitudinal bars of the lying surface, and attach
them from below with the enclosed
threaded rods.
Now, attach the mattress brackets using the
supplied self-tapping screws, if these were
not factory-installed (depending on shipping
method of the nursing care bed).
Subsequently, raise the chassis for the further assembly.
Actuate the central parking brake to prevent
an unintentional movement of the bed.
Bolt the end panels and the lying surface together.
29
Telescopic side protection:
Place the outer posts at the end of the lying
surface and the middle posts in the centre on
the longitudinal frame of the lying surface.
Insert the side guard rails onto the mounting
latches and screw them together.
The markings on the side rail receptacles
must point downwards.
Align the middle post sideways and tighten it
from below.
30
Inserting the decorative foil into the telescopic posts
Take the decorative foil (1) and push it from
below through the slot in the plug (2) into
the aluminium profile of the side rail post (3).
Please make sure that the correct side of the
decorative film is facing outwards. This will
be difficult to remove later. Push the decorative foil in until it is flush with the button (4).
On the lower plug (2) there is a snap-in lug
which prevents the decorative foil from falling out.
For continuous side rails:
Loosen the screws of the insertion at the
head end piece and pull it out slightly.
Now, insert the side guard rails onto the
mounting latches and screw them together.
After all side guard rails have been installed,
slide the end panel back and tighten the
screws again.
Check all screw connections again before operating the bed.

4.3 Bed extension
On the foot part, remove the two lower
screws of the end panel attachment.
Pull the foot end piece out, approx. 220
mm.
Take the foot bracket extension (availa-
ble as accessory) and remove both attached aluminium caps, as well as both of
the folding thumb-screws.
Clip them onto the pull-outs.
Slide the foot end piece again back, so
that the longitudinal frame and the
clipped-on part lie levelled on each other.
The end panel is then firmly attached
with the two folding thumb-screws.
Insert the foot bracket extension as shown in the Fig.

4.4 Emergency lowering - back part (standard)
In case of power or drive system failure, you
can lower the elevated back part manually.
Must be carried out always by two people!
One person lifts the back part slightly (to
take pressure off) and holds it in this position. As next step, the second person removes the locking pin from the motor.
The motor is now separated from the back
part and can be swivelled downwards.
Once the second person has left the danger
zone, the first person can lower gently the
back part.
Hold the back part by all means until it is
fully lowered.
Hazard note from Bock
Emergency lowering may be only carried out in an emergency by people who safely master this
operation.
Absolutely disconnect the bed from the mains as long as the motors have not been mounted
again.
33
4.5 Emergency lowering - back part (optional)
In an emergency, the backrest can be lowered by means of a mechanical device on the
nursing care bed. To do this, move the red operating lever upwards in the direction of the
head end piece. The speed of lowering depends on the weight of the mattress and the
weight of the patient.
Operation:
Hold the mattress bracket (1) on the backrest with one hand and move the red operating lever (2) upwards with the other hand in the direction of the head end piece (see arrow direction). The backrest moves downwards. Hold your hand on the mattress bracket
(1) until you release the control lever (2). The backrest will then be held in this position.
Make sure that the control lever (2) points vertically downwards again after the operation.
Hazard note from Bock
With heavy patients, the backrest can lower very quickly. Always lower the backrest with one
hand on the mattress bracket to check the adjustment.
Hazard note from Bock
With the practico alu SCC nursing care bed model, the head part motor must be retracted completely once with the hand control after using the emergency release.
34
4.6 Change of location
If the bed must be moved to another location, please follow these safety instructions:
– Move the lying surface into the lowest position using the button (8) of the hand con-
trol.
– Before performing a movement, pull out the mains plug and attach with the suspen-
sion device at the wood side rail, to secure the power cable against falling and being
crushed through over-travel. Make sure that the cable is not dragged over the floor.
– Before inserted the mains plug again, inspect the power cable visually for mechanical
damage (dents and kinks, abrasions and bare wires).
– Place the power cable in a way that it will not be rolled over or strained during the
operation of the bed or could be damaged when inserting the mains plug again.
– Perform the reset movement, as described on page 18 (applies to the practico alu
plus).

5 Accessories
Hermann Bock GmbH offers practical and mobility-promoting accessories to ensure that
each nursing care bed is tailored even more precisely to the individual needs of the person
in need of care. The installation is done in a quick and easy manner using the fixing points
on the bed that have already been prepared for this purpose. It goes without saying that
every element of our additional equipment offer meets the special quality and safety
standards of Bock. In addition to the standard accessories included in basic equipment,
the customer can also choose from our variety of accessories, which is available for each
bed model. These optional accessories vary depending on the bed model and are fitted to
its special functions and location of use. The range stretches from technical elements over
mattresses up to the occasional extra bed. A wide range of wooden finishes and a variety
of colours allow for the harmonious integration of each nursing care bed with any kind of
furniture.
5.1 Special dimensions
Special dimensions are an essential part of the production Hermann Bock GmbH. Optimal
lying comfort for persons in need of care who have a particular physique can only be
achieved by means of custom-built models. With its customized models, Hermann Bock
GmbH enables customers to have their nursing care bed tailored to fit the individually
physical requirements of the person in need of care. For body heights greater than 180
cm, Hermann Bock GmbH recommends the use of an integrated bed extension together
with a foot extension (refer to Accessories) that allows an extension of the lying surface
to a length of up to 220 cm. This enables even tall people to lie comfortably while maintaining the same level of functionality.
Hazard note from Bock
When using accessories on the bed or medically necessary devices as infusion stands in close
proximity to the bed, ensure particularly that there are no risks of crushing or shearing for the
person in need of care when adjusting the back and leg rests.
The representative of the service hotline of Hermann Bock are looking forward to informing you
about the best retrofitting
solution for your bed. Hotline no. 0180 5262500 (14 cents/min. for calls from landline phones,
42 cents/min. for calls from mobile phones).
A wide product range of auxiliary furniture complements the various bed models up to the complete interior design of your home. This combination creates a care and living comfort resulting
in perfect harmony.
37
6 Cleaning, maintenance and disinfection
The individual bed elements consist of high quality materials. The surfaces of the steel
tubes are covered with a durable polyester-powder coating. All surfaces of the wooden
parts are surface-sealed with an ecologically coating that is low on harmful substances. All
bed elements are easy to clean and cared for using wipe and spray disinfection means
according to the applicable cleaning requirements with respect to the various areas of
application. Observing the following care instructions will retain the usability and visual
appearance of your nursing care bed for a long time to come.
6.1 Cleaning and care
Steel tubes and vanished metal parts:
Please use a wet wipe and a regular mild household detergent for the cleaning and care
of these surfaces.
Wooden-, decorative-, and plastic elements:
All standard furniture cleaners and cleaning detergents can be used. Using a wet wipe
without detergent additives for the cleaning of the plastic elements should generally be
sufficient. For care of the plastic surfaces use a product that is specifically suitable for
plastics.
Drive:
To prevent the intrusion of moisture into the motor housing, we recommended using only
a damp rag to clean outside housing.
Spring systems ripolux neo:
Use a damp rag without adding any detergents, or, if deemed necessary, a detergent that
is exclusively suitable for plastics and clean the spring elements made of plastics. In case
of heavy contamination, remove the spring elements from the supporting elements and
the supporting elements from the frame of the lying surface. The dismounted plastics elements can be rinsed or spray-washed with hot water to get them clean. For the disinfection, the components should be sprayed with a detergent suitable for plastics. Most of the
moisture drips off the plastic surface by slightly shaking it, while the rest will dry on its
own within a very short time. Remount the elements after they have completely dried. If
required, you can also remove each of the individual lying surface elements completely
from the frame to clean them.
38
6.2 Disinfection
Disinfect the nursing care bed with a wipe disinfectant. Please adhere to the tested and
recognised procedures of the Robert Koch Institute (RKI). You can use commercially available cleaning and disinfecting agents approved by the RKI. In order to maintain the material resistance of the plastic elements such as the motor housing and decorative elements,
only mild and gentle agents should be used for disinfection. Concentrated acids, aromatic
and chlorinated hydrocarbons as well as detergents containing highly concentrated alcohols, ether, ester and ketone may damage the material and should therefore be avoided.
The list of disinfectants and disinfection methods tested and approved by the Robert Koch
Institute can be found on the Internet at www.rki.de.
6.3 Avoidance of hazards
In order to avoid dangers in connection with cleaning and disinfection, you must first observe the following regulations in connection with the electrical components of your nursing care bed. Non-observance of these guidelines may result in considerable damage of
the electrical lines and the drive.
1. Pull the mains plug and position it in such a way that contact with excessive
amounts of water or detergents can be excluded.
2. Check all plug-connections for correct position according to the instructions.
3. Check the cables and electrical component parts for damage. Should you detect
any damage, do not perform any cleaning operations but first have the defects
repaired by the manufacturer or an authorised/ licensed electrician.
4. Before starting the operation, check the mains plug for residual moisture and dry
or blow out the device, if necessary.
5. On any suspicion of the intrusion of moisture into the electrical components, dis-
connect the mains plug immediately and do not re-establish the connection. Put
the bed out of operation immediately, attach an appropriate visible label and
contact the manufacturer/supplier.
Hazard note from Bock
Use of abrasive cleansers and/or detergents containing grinding particles, cleaning pads or stainless steel cleaners for the cleaning is absolutely not recommended. Neither use organic solvents
such as halogenated/aromatic hydrocarbons and ketones nor detergents containing acid or alkaline.
Under no circumstances must the bed be sprayed with a water hose or high-pressure cleaner,
as liquid penetrates into the electrical components, and as a result malfunctions
and dangers could occur.
Clean and disinfect the bed before using it again. Also, at the same time, perform a visual inspection to check for any mechanical damages. You will find detailed information on this in the
inspection list.

8 Regular inspections with service
Regular inspections facilitate the maintaining of the highest possible safety level, and are
considered to be an important safety precaution. Medical devices must be inspected regularly in terms of safety according to the stipulated regulations of the manufacturer and
the generally accepted rules of technology. The safety-related protection measures are
subject to different requirements and demands. This also applies to the potential wear
and tear in the daily use. To prevent such risks, constant and consistent compliance with
the deadlines for regular functional testing is absolutely necessary. The manufacturer has
no influence on the operator’s adherence with respect to the observance of these regula-
tions concerning electric beds. Bock facilitates the observance of the necessary precautionary measures to be taken by means of their time-saving services.
The execution of the inspection, assessment and documentation must be performed only
by or under supervision of professional persons such as electricians or electro-technically
instructed persons who have a thorough knowledge of the relevant provisions and are
able to recognize possible impacts and hazards.
In the event that no person on the part of the user is eligible for the regular inspections
or is commissioned, the Bock service offers you the assumption of the regular inspections
with simultaneous control and observance of the corresponding intervals for a fee.
The company Hermann Bock GmbH specifies an inspection interval which stipulates that
a safety-technical inspection is to be executed at least once annually, and with each reuse of the bed.
For support purposes, Hermann Bock GmbH will provide you with the inspection list in the
assembly and operation manual for carrying out all the necessary tests. Please copy the
checklist as a form for your inspection. The checklist serves as evidence report of the performed inspection and must be kept on file.
The inspection list can also be downloaded from the Internet: www.bock.net.
Attention: Unauthorised technical changes to the product voids all warranty claims.
