1Introduction 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 for medically used beds and tested accordingly.
Our beds comply with Standard EN 60601-2-52:2010. The electrical building components
comply with safety standard EN 60601-1:2006 for medical devices.
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 bed
4. Home-care bed, pure home care bed
5. Ambulant/ residential care
1.1 Intended use
The health care bed is suitable for persons 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. The health 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. Accordingly, the health care beds are designed to be
used for the application areas 3 to 5. Any other use is considered improper and is ex-
cluded from a possible liability claim.
The Trendelenburg function may be used exclusively under supervision of medical pro-
fessionals. The health care bed is not suitable for use in hospitals. It is suitable to
transport patients. The health care bed is mobile with the patient resting in it. To pre-
pare the transport: lock the castors and drive the lying surface in the safety position.
(The clearance between the bottom of the lying surface to the floor is 18 cm). Unlock the
castors and move the bed. After the transport, lock the castors.
Attention: The beds come with no special connection options for a potential equalisa-
tion. Electrical medical devices connected to the patient´s intravascular or intracardiac
system must not be used. The operator of the medical products ensures that the combi-
nation of the equipment meets the requirements of EN 60601-1:2006.

5
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 health care bed or carry out works on it. The user is able to recognize possi-
ble hazards and/or to avoid them and to assess the health condition of the patient.
Patient/resident
Persons in need of care as well as disabled and fragile people who are lying in the health
care bed.
Qualified personnel
Employees of the operator are referred to as qualified personnel. They are entitled to
deliver the health care bed, assemble, dismantle and transport it on the basis of their
training or instructions. Besides knowing how to operate, mount and demount the
health care bed, these persons must be instructed according to the guidelines concern-
ing the cleaning and disinfection of the health care bed.
1.3 Safety instructions
The intended use/operation of all moving parts is as important for the safety of the per-
son 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 disa-
bling 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.
This is achieved by operating the key of the hand control. First, lower the lying surface to
the safety position and activate the lock function with a twist of the key (located in the
keylock on the backside). Remove the key and check the function of the hand control for
safety reasons. Make sure that it is indeed locked.

6
These recommendations apply particularly:
-if the person in need of care cannot operate the hand control safely due to cer-
tain disabilities;
-if the person in need of care or the caregivers could be at risk due to those acci-
dental 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 in the side rails of the adjustment range. If the side rails are adjusted, pay atten-
tion 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/animals in the area between the floor and
the raised lying surface. Danger of being crushed is particularly high in these areas.
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
capacity, please refer to the type plate on the lying surface frame of the bed.
1.4 Service life / warranty
This health care bed was developed, designed and manufactured for safe operation over
a long period of time. With proper operation and maintenance, this health care bed has
an expected service life of 15 to 20 years. The service life depends on operating condi-
tions and frequency.

2General description of the functions
Construction design and function
The lying surface with 4 function areas
The lying surface standard consists of a slatted comfort frame (as an option, it can be
also provided with a metal lying surface or special suspension systems) and is divided
into four functional areas: Backrest, solid seat, upper and lower leg rest.
The comprehensive lying surface frame is welded from a steel/aluminium tube and
stove-enamelled with a PES-powder coating. The variable height adjustment of the lying
surface is electric and stepless. It is carried out by 24 V DC motors and controlled by the
smooth keys of the hand control. 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. The electronic hand
control also allows an automatic 3-way function to set a stretched leg elevation and the
chest and the knee bending part.
The chassis
The height adjustment of the beds takes place through two telescoping aluminium lifting
columns and a main frame with individual drives. The surface of the tubular steel struc-
ture is stove-enamelled with a PES-powder coating.

10
The side rail
Any health care bed can be equipped on both sides, each 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 rails can be easily operated through an ergonomically de-
signed release button. Depending on the model, shorter or longer partitioned side rail
variations are available.
Operating the telescopic split 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 piece of the health care bed, right next to the
metal guides for the side rails.
To lower the side rail element, hold the upper knob of the
middle post with one hand, lift it up slightly and press with the
other hand the trigger button on the middle post in direction
of the inside.
The side rail opens at the corresponding place and can be
easily lowered downwards as far as it will go. The side rail is
now diagonal.
To lower also the other side, please hold the side rail on the
side of the end piece in the gripping groove, release the trigger
button on the end piece of the health care bed and lower the
side rail slowly to the bottom.

11
The side rail is now in a low position.
If the side rails should be placed in the top position to aid in
fall prevention, reach with both hands in the centre of the
gripping groove in the upper ride rail and pull the side rail
upwards until you hear it click into place at both ends. The side
rail is now in a pulled-up position.
When using the telescopic (divided) side rails on this health care bed, it is necessary to
install four adjustable feet under the lying surface to prevent that the telescopic post of
the side rail sits on the floor. The screwed-on adjustable feet allow lowing of the bed
only to a minimum lower height of 15.5 cm.
Hazard note by Bock
Use only original Bock side rails, which are available as accessories for every health care bed.
Use only technically flawless and non-damaged side rails with the allowed 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 side rails, which secure the side rails for any possible damage.
The operation of side rails should be done with great care. Fingers can be quickly pinched be-
tween the longitudinal pieces.

Hazard note by 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.

3Electric components
3.1 Drive:
The drive unit consists of individual drives for the electrical adjustment of the back and
leg rest part. The level adjustment takes place via two lifting columns that are attached
to the head or foot end. A switching power supply with a rectifier that converts the input
voltage into low voltage power of 29 VDC (direct current) is part of the internal control
box. The motors, lifting columns and the hand control function with this non-hazardous
low voltage.
A power adjustment provides constant 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% (2
min. ON / 18 min. OFF) means that any electronic adjustment can be operated maximal
2 minutes. After that, the unit switches off for 18 minutes (protection against overheat-
ing).
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 drives,
the thermal fuse immediately shuts off the power supply to the bed. After a cooling
down time of approx. one hour, the power will be again automatically supplied.
3.2 Locking device for all functions
The series hand control is equipped with a built-in locking device, which allows the care
givers to lock the hand switch via a key completely or partially for its operation.
3.3 Lockable hand control (first-fault protected)
The base functions can be controlled through the ten operation keys on the hand con-
trol. The three icons in the centre indicate a special function that can be carried out by
simultaneous applying finger pressure on the adjacent keys. The individual keys are
marked with corresponding symbols. The servomotors run until as long as a correspond-
ing 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 pre-
ferred spot on the bed.

Hazard note by Bock
Please make sure that the hand control cable is not lead under one of the aluminium longitu-
dinal frame bars. In case of lowering the bed completely into its ultra-low position (floor level),
the cable can get damaged.
Execute the reset-function before the initial operation of the bed and after each disconnection
from the power supply system.
Pay attention to the position of the castors, especially when using the comfort-sitting, Trende-
lenburg and Anti-Trendelenburg position.
Respect that when using accessories and splitted side rails, the bed is only allowed to go down
to the second safety stop at 15.5 cm. When lowering the bed to its ultra-low position (floor
level), pay attention to the high crushing hazards (feet, toes and objects e.g. cables) under the
aluminium longitudinal bar and end panels.

3.5 Caution: Electric drive
Hermann Bock calls the electrically operated nursing and therapy beds health care beds,
because through their multiple functions, they allow the person in need of care to sup-
port the healing process mentally and physically and relieve pain at the same time. Elec-
trically 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 pre-
vent 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 inad-
missible and excessive leakage currents exist or if liquid was spilled in the motor hous-
ing, e.g. during improper cleaning. This damage can cause malfunction of the control,
which could result in unwanted movements of single bed elements, posing a risk of inju-
ry for the operator and the person in need of care.

4Drives
4.1 24 Volt drives / lift columns
Hermann Bock GmbH equipped health care beds with the various drive systems of the
companies Dewert, Baumeister and Limoss.
4.2 Drive systems
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. Due to a detailed interior structure, the construction of the housing
interior creates an essential prerequisite for the precise integration of the drive technol-
ogy. The individual drive is characterized through a particularly easy to follow assem-
bly/disassembly design and also an easy installation of the control electronics. The drive
has a primary fuse in the mains adapter.
Hazard note by Bock
All drive components must not be opened!
Troubleshooting or exchanging single electrical components may be performed only by spe-
cial qualified personnel.
