ENVIRONMENTAL
SUSTAINABILITY
Betten Malsch GmbH hospital beds are manufactured in line with
the relevant regulations using state-of-the-art processing technol-
ogies, and contain no hazardous materials. The materials used to
nish surfaces are CFC- and solvent-free.
Hospital beds that are taken out of service due to their age or
irreparable damage must be disposed of in line with local disposal
regulations.
Caution! Please observe the relevant local regula-
tions when disposing of metal, wood and electrical
waste.
The hospital beds made by Betten Malsch GmbH are used in the
care of patients with physical limitations. The beds are designed
exclusively for this purpose. The functions of these hospital beds
assist the care sta in their daily work and oer convenient solu-
tions for positioning the patient and compensating for certain
symptoms experienced by patients in clinics and hospitals or com-
parable medical facilities. This complies with working environment
1, 2, 3 and 5 as stipulated by IEC 60601-2-52:2009 / AMD1:2015.
If the hospital beds are to be used for other applications, prior
written agreement from Betten Malsch GmbH is required.
The product is intended for use as a care aid or health device.
As such, it is subject to the regulations of the relevant insurance
associations. The hospital bed is a medical product with regard
to applicable industry standards and regulations. Therefore, this
product must only be used under medical supervision.
The hospital beds described in this instruction manual are ap-
proved for adult patients with a body weight of at least 40kg
and a height of at least 146cm. In accordance with the stand-
ard IEC 60601-2-52:2009/AMD1:2015, the beds must not be
used by patients whose body weight and height is below these
limits or who have a BMI under 17, as the risk of injury is sig-
nicantly increased for this group.
Caution! The use of incompatible side rails and
mattresses can lead to injury, as body parts may
become trapped.

NOTES TO THE
INSTRUCTION MANUAL
PICTOGRAMS / SYMBOLS
The following instructions and guidelines in this instruction man-
ual are intended for care sta or other persons and sta tasked
with operating and using the hospital bed.
The instruction manual must be accessible to per-
sonnel at all times to avoid operating errors and to
guarantee fault-free operation. The care sta must
have a good understanding of the hospital beds and
be trained in their operation before using them for
the rst time. The instruction manual must be used
for this training.
This instruction manual has been written for the IMPULSE KL
hospital bed. The images, graphics and texts it contains may dier
from the equipment supplied.
The manufacturer oers technician training for
maintenance and servicing work on their hospital
beds. A certicate obtained as part of this training
authorises the holder to carry out technical work
independently on the beds.
For better orientation, this instruction manual uses the picto-
grams described below.
Important!
Instructions labelled in this way must be strictly ob-
served in order to avoid injury or damage!

SAFETY INSTRUCTIONS
It is important that the following safety instructions are ob-
served to prevent risks to patients as well as carers, and to
avoid any damage to the hospital bed:
The instruction manual must be read and observed before
using the hospital bed.
The information on the rating plate must be observed! The
information on the rating plate is explained in detail on
p. 16 of this instruction manual.
In the event of any faults or defects that could endanger
persons, the bed must not be used.
Electrically adjustable hospital beds must be operated by
trained sta only.
Before the bed is used for the rst time, the operator must
ensure that it is safe to use and in good condition.
To prevent the patient from falling while getting into or out
of the bed, the castors must always be set to the braked
position.
The bed can be moved into various positions. When doing
so, take care to ensure no parts of the body or other ob-
jects are located in the adjustment area.
Only care sta are permitted to adjust the side rails. When
adjusting the sleeping surface position, take care to ensure
the patient does not come into contact with the side rails
to avoid trapping any part of the body.
The functionality of the side rails must be checked every day.
They must not bear any load of over 75 kg vertically or over
50 kg horizontally.
When using CPR (optional, mechanical emergency lowering
of the back rest), always additionally relieve the load on the
back rest by hand to prevent the back rest from dropping in
an uncontrolled manner.
The IMPULSE KL hospital bed features a battery-operat-
ed emergency mode. This allows the one-o lowering of
the sleeping surface in the event of a power cut. To ensure
this functionality, we recommend an annual test of the 9 V
batteries as part of the technical safety check and regular
battery replacement every two years or after each use of
the emergency lowering mechanism.
p. 49 Battery replacement.
The hand controller functions can be locked or released
using the sta controller or the key switch on the rear side
of the hand controller. Check with the hand controller that
the locking function has taken eect.
p. 20 - p. 21 Hand controller symbols
The drive system used must be operated using a VDE-
approved power source, i.e. a 100 -240 V, 50 / 60Hz mains
socket.
The mains connection cable is also protected by a mechani-
cal strain relief device. Nevertheless, take care to ensure that
the cable is not damaged by sharp edges, mechanical loads
or pinch / shear points.

10 |
The hand controller can be placed exibly. When placing
the hand controller, take care to ensure that it cannot be
triggered accidentally (e.g. by being trapped between two
objects). The hand controller must be freely accessible.
When using the hospital bed in a patientʼs room, safety
distances from walls, window ledges and other furnishings
must be observed. The safety distances depend on the de-
sign and model of the hospital bed and are based on the
height adjustment and the tilting motions of the bed. The
minimum distance is 30 mm.
Improper use of the bed may cause hazards. Examples of
improper use include:
§Unauthorised activation of the electrical functions
§Use of the bed by persons with a body weight of less
than 40 kg or a BMI of less than 17, or a height of less
than 146 cm p. 7 Specic function
§Moving the bed by pulling on the mains cable or side rails
§More than one person adjusting the bed at the same time
§Activation of the functions by patients without prior
instruction
§Pulling the mains cable to disconnect it from the power
supply
§Moving the bed on sloping or unsurfaced ground
In line with the standard DIN EN 60601-2-52:2016, when
choosing a mattress, it is important that there is a minimum
distance of 22 cm between the top of the sleeping surface
and the top of the side rail in its fully extended position. The
mattress used must meet the applicable safety standards.
The constant presence of liquid in the area of the motor
must be avoided (e. g. incontinence).
For safety reasons, the handle on the trapeze bar must be
replaced in its entirety every 5years.
Servicing and repairs on electrical components must be car-
ried out by specially trained sta, and only original replace-
ment parts from the manufacturer may be used.
The hospital bed is not suitable for extended operation
beyond a working cycle of two minutes. If the mains adapter
is overloaded or if it overheats, it will shut o automatically.
Further operation is possible only after a 30-minute cool-
down phase. (Observe the drive manufacturerʼs notes on
the rating plate!)
It is essential to avoid obstructing any part of the bed mech-
anism, as this can lead to damage or complete disabling of
the drive system due to overheating.
Likewise, the safe working load must not be exceeded.
If an immobile patient remains in the same position for an ex-
tended period of time without the use of additional position-
ing aids, this can lead to pressure sores. The manufacturer of
the hospital bed is not liable for this in any way.

|11
Electrically operated hospital beds are active medical prod-
ucts and must be maintained according to Article 7 of the
Medical Devices Operator Ordinance (MedProd-BetrV.)
These maintenance measures must be carried out regularly
(at least once per year). They must include visual and func-
tionality checks of functional and electrical safety in line with
VDE0751. p. 47 Maintenance
Furthermore, electrically operated hospital beds are electri-
cal appliances whose safety is the responsibility of the em-
ployer. The supervisory function of this obligation is the re-
sponsibility of the Employersʼ Liability Insurance Association
for Health Service and Welfare Work (BGW) and the Trade
Supervisory Board (Gewerbeaufsichtsamt). The regulations
of the employersʼ liability insurance associations apply, par-
ticularly those of the German statutory accident insurance
body (DGUV), rule3 of which stipulates regular inspections
of movable electrical equipment at a recommended interval
of six months, but at least once a year. These inspections
may only be carried out by a certied electrician or person
with electrical training using specialist measurement and in-
spection equipment. The inspections according to DGUV
rule 3 can be conducted by specialist sta trained by the
manufacturer as part of the inspections and maintenance
service for medical products.
Electrically operated hospital beds are active medical prod-
ucts and must be listed in an inventory for each site in line
with Article 13 of the German Medical Device Operator
Ordinance (MedProd-BetrV). It is advisable to also docu-
ment the correct implementation of the required checks
and servicing in this inventory and to specify the date of the
next inspection. The required protocols concerning checks
already performed must be appended to the inventory.
Proper execution and traceable documentation of the
technical checks, maintenance and servicing work prescribed
by the manufacturer, as well as the technical safety checks,
are required in order to preserve the warranty rights of the
purchaser. If the operator of a medical product does not
meet their obligations, this could lead to the risk of dam-
age and accidents for which the manufacturer is explicitly
notliable.
Maintenance work must be carried out and documented by
trained sta.
The bed should be left in the lowest position when the
patient is unattended to reduce the risk of injury caused by
falling out of bed.
If the mains connection cable is damaged, the bed can
no longer be used and must immediately be taken out of
operation.
Improper use of the mains connection cable can result
in hazards (e. g. electric shock). Examples of this are cable
breaks due to kinking, shearing or other mechanical damage.
When using other ME devices in conjunction with the hos-
pital bed, precautions must be taken to prevent damage to
the device cable or other components of the ME device
resulting from crushing between the movable parts of the
medically used bed.

12 |
The hospital bed is not suitable for use in the vicinity of
active facilities that use high-frequency surgical devices.
The hospital bed is not suitable for use in HF-shielded rooms
used for magnetic resonance imaging in which high-intensity
EM disturbance variables occur.
The use of this hospital bed directly next to or in conjunc-
tion with other electrical devices (e.g. stacked) must be
avoided, as this can lead to faulty operation. If using the bed
in the manner described above is absolutely necessary, the
devices involved should be subjected to a function test for a
longer period of time in order to rule out malfunction due
to interference.
The use of accessories, transducers and cables other than
those specied or provided by Betten Malsch GmbH can
cause increased emissions of electromagnetic interference
or reduce the electromagnetic interference resistance of
the device and thus lead to faulty operation.
Portable HF communication devices (radio devices) – in-
cluding their accessories, such as antenna cables and exter-
nal antennas – must not be used closer than 30 cm to the
parts and cables of hospital beds as designated by Betten
Malsch GmbH. Non-observance can impair the perfor-
mance of the hospital bed.
The emissions of this device are below the thresholds de-
ned by IEC/ CISPR 11:2009, Class A and thus permit the
use of it in industrial environments and hospitals. This de-
vice may not provide adequate protection against wireless
services if used in residential areas (for which Class B is
normally required according to CISPR 11). The user may
have to implement remedial measures such as relocating or
repositioning the device.
Servicing and maintenance tasks may not be performed
while the ME device is in use.
