1Instruction and general notes
The different nursing bed systems from Hermann Bock GmbH meet special requirements
for use in nursing and therapy facilities as well as for care at home. At the same time,
reliable functionality and durability distinguish each individual care bed as being of partic-
ularly high quality. With proper operation and inspection, the care bed remains corre-
spondingly maintenance-free. Each Hermann Bock care bed only leaves production after
passing a quality test in the final inspection. The care beds are manufactured and tested
in accordance with the currently applicable standards for medically used care beds.
The Nursing care beds are compliant with the EN 60601-2-52 standard. The electrical com-
ponents are compliant with the EN 60601-1 safety standard for medical devices. Nursing
care beds are medical devices and are categorised as Class 1.
The standard divides Nursing care beds into five different usage environments:
1. Intensive care in a hospital, intensive-care bed
2. Acute care in a hospital or other medical facility, nursing care bed in a hospital
3. Long-term care in a medical environment, in nursing care bed
4. In-home care, solely for use as a “home-care nursing care bed”
5. Outpatient care
1.1 Intended use
The nursing care bed is suitable for patients 146 cm or greater
in height. The patient’s weight may not exceed the maximum
body mass indicated on the nameplate, and must be greater
than 40kg. The patient’s body mass index (BMI) must be 17 or
greater.
The nursing care bed may be used in nursing or retirement homes and rehabilitation fa-
cilities. Its purpose is to alleviate a patient’s disability and to make it easier for nursing
staff to provide care. In addition, the nursing care bed was designed as a convenient solu-
tion for patients requiring in-home care and for people with disabilities. The Nursing care
beds described below are thus intended for usage environments 3 to 5 above. Any other
use is incompatible with the intended use and excluded from any claims of liability.
The care bed is delivered without the Trendenburg function as standard. The Trendelen-
burg function is available as an option for application environments 3 and 5.
The Trendelenburg function may only be used by qualified medical personnel. Nursing
beds intended for application environment 4 are equipped with a manual switch that can-
not control the Trendelenburg function.

EN
6
The nursing care bed is not intended for use in hospitals. If the nursing care bed is
equipped with open casters, the nursing care bed can be used to transport patients. The
nursing care bed can be moved while the patient is lying in it. To prepare for moving the
bed, lock the casters and lower the mattress support frame to the lowest horizontal posi-
tion. Release the casters and move the bed. Once transport is complete, lock the casters.
If the nursing care bed has covered casters, the nursing care bed is not designed for trans-
porting patients. In this case, the bed can only be moved within the patient’s room (in-
cluding while the patient is lying in the bed), e.g. for cleaning or to provide better access
to the patient. If the nursing care bed has fixed feet, it cannot be moved.
The nursing care bed is suitable for reuse. Please follow all guidelines in these assembly
and operating instructions for cleaning, care and disinfection of the nursing care bed prior
to reuse. Please pay particular attention to all information about inspecting the bed.
Note: The beds have no specific connectors for equipotential bonding. Electrical medical
devices with intravascular or intracardiac connections to the patient may not be used. The
operator of any medical devices is responsible for ensuring that the combination of de-
vices meets the requirements of EN 60601-1.
This manual contains safety instructions. All persons who work with the beds must be
familiar with the contents of this manual. Improper operation may result in hazards.
1.2 Contraindications
This bed is intended only for patients/occupants who meet the following minimum body
size and weight requirements:
Height of 146 cm or greater
Weight of 40 kg or greater
Body mass index of 17 or greater
1.3 Definitions
Operator
An operator (e.g. a health care supplier, equipment dealer, institution or funding agency)
is any natural or legal person that uses the Nursing care beds or on whose behalf the
Nursing care beds are used. The operator is always responsible for proper use of the prod-
uct.
User

EN
7
Users are persons who are authorised on the basis of their education, experience or prod-
uct training to operate or perform work on the nursing care bed. The user is able to iden-
tify and/or prevent possible hazards and to assess the patient’s state of health.
Patient/Occupant
The person requiring care, infirm person, or person with a disability who is lying in the
nursing care bed.
Technical personnel
Technical personnel are employees of the operator who are authorised on the basis of
their education or training to deliver, assemble, disassemble and transport the nursing
care bed. In addition to operation, assembly and disassembly of the nursing care bed,
these persons have been instructed in the guidelines for cleaning and disinfecting the
nursing care bed.
1.4 Obligations as operator
In Germany, observe your obligations as an operator in accordance with the Medical De-
vices Operator Ordinance in order to ensure that this medical device can be operated
safely in the long term without any hazards. In other countries, the applicable national
regulations on the obligations of the operator must be observed.
Point out the storage location of these instructions for use to the nursing staff in accord-
ance with the Medical Devices Operator Ordinance. In other countries, the applicable na-
tional regulations must be observed. Instruct the nursing staff in the safe operation of the
nursing bed with the aid of these instructions for use before the initial start-up.
Draw the attention of the nursing staff to possible hazards in case of improper use of the
nursing bed. This applies in particular to the handling of the electrical drives and side
guards.
According to the Medical Devices Operator Ordinance (MPBetreibV), operators must rec-
ord their stock of electrically adjustable hospital and care beds (active medical devices)
and keep an inventory.
1.5 Safety instructions
Proper use of all moving components is essential for preventing hazards to the patient
and for the safety of the patient’s family and/or nursing staff. Ensuring proper use requires
proper assembly and operation of the nursing care bed. The individual patient’s physical
condition and the type and extent of their disability must also be taken into account when
using the nursing care bed.

EN

Avoid hazards from accidental motorised position changes and other incorrect operations
by using the locking mechanism. When the user (e.g. the nursing staff or family member
caring for the patient) leaves the room, all of the bed’s functions should be locked using
the key on the hand switch. To do this, first lower the mattress support frame to the low-
est position, then activate the locking function by turning the key in the lock located on
the back of the hand switch. Remove the key and test the hand switch functions to ensure
that it has been properly locked.
It is especially important to follow these recommendations
if the patient cannot safely operate the hand switch functions themselves due
to certain disabilities,
if the patient or nursing staff could be put at risk by unintended changes in
the bed’s position,
if the side rails are raised and there is a risk of pinching or crushing,
if unsupervised children are present in the room with the nursing care bed.
When the hand switch is not in use, always ensure that it is safely hung on the storage
hook and cannot fall to the ground.
The nursing care bed must only be operated by nursing staff or family members who have
been trained in its use, or in the presence of trained users.
When changing the bed position, it is especially important to ensure that limbs and ex-
tremities are clear of the side rails in the area being repositioned. Also ensure that the
patient is lying in the correct position when repositioning the side rails themselves.
Before using any motorised repositioning function, always check that limbs and extremi-
ties are clear of the area between the bed frame and the headboard or footboard of the
bed, and ensure that no children or pets are in the space between the floor and the raised
mattress support frame. The risk of pinching or crushing is especially high in these areas.
Also check for objects located near or beneath the nursing care bed. Remove such objects
to avoid damage during repositioning.
The permissible patient weight depends on the total weight of other accessories present
at the same time (mattresses or other electrical medical devices). Please check the name-
plate on the mattress support frame for the maximum safe operating weight.
Service and maintenance may not be performed when the bed is in use by a patient.

EN
9
The nursing care bed may only be used for patient care and rest. Functions to reposition
the head and foot of the nursing care bed are intended solely for repositioning the corre-
sponding areas of the patient’s body. The nursing care bed must only be used for its in-
tended purpose, and must not be used improperly or for any unintended purpose.
The patient must be immediately removed from the bed in case of malfunction or equip-
ment failure.
Use of incompatible side rails may result in pinching of extremities.
To deactivate the nursing care bed and safely halt operation of the bed, remove the wall
plug from the socket.
1.6 Usable lifespan
This nursing care bed was designed, engineered and manufactured to operate safely for a
long period of time. When used and operated correctly, this nursing care bed has an ex-
pected lifespan of 10 years. The actual lifespan will depend on the conditions and fre-
quency of use.
1.7 Warranty

1.9 Installation site requirements
Hermann Bock GmbH is not liable for any floor damage that may result from everyday use
of this product.
To avoid marks or impressions on the floor, the floor surface should comply with the rec-
ommendations of the FEB (Fachverband der Hersteller elastischer Bodenbeläge e. V., the
German Trade Association for Elastic Floor Coverings). FEB Technical Information Docu-
ment no. 3 can be consulted for this purpose.
Bock Safety Note
When using multiple electrical devices simultaneously, small electromagnetic interactions be-
tween such devices may occur, e.g. static and distortion on a radio, especially in direct proxim-
ity to the activated nursing care bed. In these rare cases, increase the distance between de-
vices, use a different wall socket, or temporarily switch off the device causing or affected by
the disturbance.
If the nursing care bed is to be used with electrical medical devices, contrary to its intended
purpose, then the nursing care bed’s functions must first be deactivated via the integrated
locking function on the hand switch for the duration of such use of these devices.

2Overview of nursing care bed functions
Construction and function
Corrosion protection
Nursing care beds from Hermann Bock GmbH are designed and engineered to operate
safely for a long period of time. Corrosion protection has therefore been applied to all
corrosion-prone materials. All metal parts are treated with surface protection. Steel parts
are either galvanised or stove-enamelled with a PES powder coating, and aluminium pro-
files are anodised.
Four-zone mattress support frame
The mattress support frame comes standard with a comfort slatted frame (or can alterna-
tively be fitted with aluminium bars or special spring support systems) and is divided into
four functional zones: Back rest, fixed seat, thigh rest and lower leg rest.
The outer edge of the mattress support frame is constructed from tubular steel. The tub-
ular steel segments are stove-enamelled with a PES powder coating on their outer surface.
Continuous electrical height adjustment is provided by DC motors with safety extra-low
voltage from 29 to 35V and controlled with an easy-to-operate keypad on the hand switch.
The back rest can be electrically adjusted. The leg portion consists of a two-part foot bar.
Each individual position can be continuously adjusted with the push of a button on the
hand switch. In the event of a power outage, the back and leg zones can be lowered with
power from a 9-volt battery.

The height of the nursing care bed can be adjusted either via two height-adjustable actu-
ators or through a base frame equipped with a single or dual drive system. The outer sur-
face of the tubular steel frame is stove-enamelled with a PES powder coating.
Side rails
Each nursing care bed can be equipped with two side rails on each side at a specific safety
height. The side rails can be raised and lowered along a track. Impact absorbers ensure
quiet slider operation, and the ends are fitted with functional end caps. An ergonomically
shaped release button allows for easy adjustment of the side rails.
2.1 Adjusting the continuous side rail
The release button for adjusting
the continuous side rails is lo-
cated just above the upper side
rail in the sliding track.
To lower the side rails, hold the
groove in the upper side rail, lift
the side rail slightly, and press
the release button on either the
headboard or footboard. The
side rail is then released on that
side and can be easily lowered to
the end of the track. The side rail
is now in a diagonal position. To
lower the other side, perform
these steps again at the opposite
end of the bed. The side rail is
now in its lowered position.
Bock Safety Note
Always lift the side rail slightly before pressing the release button! Failure to do so will damage
the release mechanism.

EN
15
To raise the side rails to the upper position for protection against falls, hold the upper side
rail in the centre of the groove and pull the side rail up until you hear it click into position
at both ends. The side rail is now in its raised position.
The primary purpose of the side rails is to protect the patient from falling out. For ex-
tremely emaciated patients, the side rails no longer offer adequate fall protection, and
additional protective measures must be taken, e.g. by placing additional fitted side-rail
padding (product accessory) in the bed.
The gap between the continuous side rails must be no larger than 12 cm. The side rails
must not be left in a diagonal position during use.
Bock Safety Note
Use only original Bock side rails, which are available as product accessories for each type of
nursing care bed.
Use only side rails that are undamaged and free of technical defects, and ensure that the gap
between rails is always within the permissible range.
Ensure that the side rails click securely into position.
Before placing the side rails and before each new use, check for damage on all mechanical
parts on the bed frame and the side rails that serve to hold the side rails in place.
Always operate the side rails with great care, as fingers can easily be pinched between the
rails.
Bock Safety Note
Always operate the side rails with great care, as fingers can easily be pinched. Only use the
side rails in accordance with the mode of operation described here. Any other use can lead to
increased risks and is prohibited. Use only original Bock side rails. Use only side rails that are
undamaged and free of technical defects, and ensure that the gap between rails is always
within the permissible range. Ensure that the side rails click securely into position.
Before placing the side rails and before each new use, check for damage on all mechanical
parts on the bed frame and the side rails that serve to hold the side rails in place.
Bock Safety Note
Always be aware of the increased risk of pinching associated with a locked side rail when ad-
justing the position of the back and thigh rests.

3Electrical components
3.1 Drive Unit
Depending on the model, the drive unit consists either of a dual drive system with two
separate drive units for motorised adjustment of back rest and leg rest positions, or two
individual drive systems. The level of the lifting frame is adjusted with one or two individ-
ual drive systems (depending on the model). The motors and the hand switch are con-
nected to the internal control box. The power supply unit converts the input voltage to a
safety extra-low voltage of no greater than 35V DC. This safety extra-low voltage is used
to operate the motors and the hand switch. Cables are double-insulated and the power
supply unit has a primary fuse.
The internal emergency lowering mechanism uses a 9V block battery. In addition, a power
adjustment system ensures constant operating speed. These safety measures correspond
to protection class II, and liquid ingress protection
meets the standards of protection code IPX4.
The maximum duty cycle is indicated on the nursing
care bed (nameplate). For example, a 10% duty cycle
(2 min. ON / 18 min. OFF) means that each electri-
cally-powered adjustment can be run for no longer
than 2 minutes out of every 20 to prevent overheat-
ing.
If the maximum motor activation time of two minutes
is exceeded, for example due to excessive use of the hand switch, and the motors over-
heat as a result, the thermal fuse immediately cuts off all power to the bed. After a
cooldown time of approx. 1 hour, the power supply is automatically restored.
If the lifting drives do not move synchronously and this leads to an inclined position of the
lying surface, move the lying surface height to the upper or lower end position. This ena-
bles an automatic compensation of the two lifting drives and thus a horizontal lying sur-
face.
Bock Safety Note
The 9-volt batteries in the control unit must be checked once a year, and replaced if necessary.
In addition, visual inspections should be conducted on a regular basis.

3.2 Caution: Electric drive system
With its wide variety of functions, the electrically powered nursing care bed provides the
patient with substantial physical and emotional support for their recovery process, while
also alleviating pain. As medical devices, electrically powered beds require a high level of
diligence with regard to regular safety inspections. This includes safe use of the nursing
care bed, daily inspection of electrical equipment, and proper cleaning and mainte-
nance.
To avoid cable damage, cords and cables should be placed outside of any area where dam-
age could occur. Any contact with sharp-edged components should also be prevented. To
avoid risk of injury from electric shock, any possibility of excessive touch voltage should
be eliminated. Such circumstances are especially likely to occur when the mains power
cable has been damaged, when dangerous and excessive leakage currents are present, or
when liquid has entered the motor housing, e.g. as a result of improper cleaning. Such
damage can result in control unit malfunction which can in turn lead to unintended move-
ments of individual bed components, raising the risk of injury to patients and users.
3.3 Drive systems
Hermann Bock GmbH equips its beds with drive systems from Limoss and from Dew-
ertOkin GmbH (drive system with external switch-mode power supply).
Bock Safety Note
Do not open any components of the drive system!
Only specifically authorised professionals are permitted to repair any defects or replace indi-
vidual electrical components.
Bock Safety Note
The motors have IPX4 protection against splashing water. Cables must not be pinched or
crushed. Repositioning of moveable parts may only be used for the intended purpose. Her-
mann Bock GmbH assumes no liability for unauthorised technical modifications.
Bock Safety Note
Never attempt to repair electrical equipment yourself. In some cases there may a risk of life-
threatening electric shock! Contact either the Customer Service department at Hermann Bock
GmbH or an authorised professional electrician to repair any defects in accordance with all ap-
plicable VDE guidelines and safety requirements.

EN

The dual drive system for continuous repositioning of the mattress support frame, and
the linear drive unit that serves as the single drive system for adjusting the height of the
lifting frame, each consist of four main components.
Housing
Motor
Gearbox
Spindle with nut
The housing design for the dual and single drive systems ensures long-term operation of
all drive components. The special construction design is based on two load-bearing hous-
ing shells. The inside of the housing has a detailed internal construction that provides a
precise fit for the drive unit hardware. The housing allows for simple assembly and disas-
sembly, and provides generous space for installation of the emergency lowering battery
and control electronics. The dual drive system also features a robust side shutter.
3.4 External SMPS (switch-mode power supply)
The drive system includes a primary fuse in the power supply unit and an emergency low-
ering mechanism. The SMPS (switch-mode power supply) is an electronic transformer that
warms up only minimally under load and has an integrated electronic power monitoring
unit. The resulting system provides constant voltage up to the load limit (no loss of speed)
and strong protection against overloading. The external transformer provides safety right
from the wall socket, where it transforms the mains voltage directly into the safety extra-
low voltage used to operate the nursing care bed. It is connected to the mains power
supply cable by means of a plug coupling, so that it can be replaced separately in case of
a defect.
The power supply unit complies with European guidelines for household electrical devices,
so it also maintains low energy consumption of no more than 0.5 watts in standby mode
and can be used internationally with input voltages from 100 V to 240 V. No alternating
electromagnetic fields can be detected at the SMPS, and such fields are even lower during
operation (due to the very low direct current) than when disconnected from mains power.

EN

3.5 Box motor connections
3.6 Operating status display of the external SMPS switching power supply unit
The SMPS switched-mode power supply has an LED that can indicate the following oper-
ating states:
LED On: Ready for operation
LED Off: Discharged, not connected
LED Flashing: Error, thermal overload, or short circuit.
After disconnecting the mains plug or the connection to the motor, the LED "glows" and
then goes out.
