Foreword
We congratulate you on your choice of a Völker hospital bed and would like
to thank you for your confidence in our company and its products.
Before purchase, we are sure that you received detailed information and
advice that convinced you of the many benefits of our hospital beds –
benefits that in this configuration are truly unique.
The fact that a Völker hospital bed – in spite of its many functional features
and technical refinements – does not look like a piece of sterile institutional
equipment undoubtedly made your decision to purchase all the easier.
This user’s manual is intended to provide you with information on the
technical features of Völker S 960-1 to help you to get the most out of its
many functions.

CAUTION!
Refer to user’s manual!
Please read safety instructions!
WARNING! – Serious injury can be caused when moving powered parts of the bed. Make
absolutely sure that there are no parts of the body poking through the safety frames
during electrical operation. Ensure without fail that there are no people, pets or objects
beneath the bed.
WARNING! – Increased safety measures are necessary when the bed is being used …
1. … by a child under 12 years of age,
2. ... by a person with reduced mental faculties,
3. ... for psychiatric purposes.
WARNING! – Automatic mode should not be selected when the bed is being used …
1. … by a child under 12 years of age,
2. ... by a person with reduced mental faculties,
3. ... for psychiatric purposes.
WARNING! – In order to avoid falls, always return the bed to lowest position after each
use of the adjustment functions. Make absolutely sure that
a) the bed is in lowest position before getting into or out of it, and
b) the brakes are applied.
WARNING! – Safety frames only mark the limits of the bed. Other appropriate measures
must be used to restrain patients.
WARNING! – Children under 12 and people with reduced mental faculties may only
occupy Völker beds when the safety frames are covered by protective covers. Risk of
injury. Refer to user’s manual.

WARNING!
> Only use original spare parts for repairs.
> Only repair bed when it is in lowest position.
> Pull out power plug before repair or cleaning.
Refer to user’s manual and maintenance manual for further safety instructions.
1.5. Electromagnetic/-static interference
To ensure protection against electromagnetic and electrostatic interference (EMV),
the S 960-1 hospital bed fulfils all the requirements of the relevant sections of the
German medical products law (MPG).
Basis of testing for:
− high-frequency interference: EN 60601-1-2:1993
limiting values according to: EN 55011 Group 1, Class B:1998
limiting values according to: EN 55014:1993
− resistance to jamming: EN 60601-1-2:1993
1.6. Before using the bed for the first time
Before the bed is put into service for the first time, this user’s manual must be
closely read by all those responsible for nursing care.
Before the bed is put into service for the first time, it is absolutely essential to carry
out a functional test as described in Chapter 8.
Before first use, carers must receive detailed instructions in the operation of the
bed. In addition, carers must be made fully aware of potential dangers that can arise
in spite of the correct operation of the bed (see Chapter 4).
1.7. Checking the operational safety and condition of the bed
Before putting the bed into service, it is essential to make absolutely sure that it is in
good working condition and safe to use. This test must not only be carried out
before first use, but continuously throughout the service life of the bed. If necessary,
the bed must be tested daily or after each shift to ensure that its use does not
endanger anybody. To reduce maintenance to a necessary minimum, the bed should
be cleaned, disinfected and tested as soon as possible after each use so that it can
be used again without delay or risk (see Chaper 8, Functional test). Please note that
preparation in a cleaning plant offends against this principle (see Chapter 9).
In cases of malfunctioning, it may be necessary to transfer the patient to another
bed.

Völker hospital bed User’s Manual Model S 960-1
1.8. Position of the hospital bed – Danger of falling out of bed
In the case of unsupervised patients, we recommend that the bed is put into its
lowest position to minimise the risk of injury due to falling out of bed. In other cases,
it should be put at a height proportionate to the size of the patient.
1.9. Four-castor central braking system – Caution! Risk of accident
Unless in transport, the brakes must always be applied so that patients can use the
bed as a support when accessing or exiting it. Serious falls can result through an
unbraked bed rolling away. After applying the brakes, check that the bed is really
immobile, ie that the brakes are fully applied to all four castors.
Height adjustment – Risk of entrapment between bed-frame and
chassis
When adjusting the bed, make absolutely sure that no limbs, bedding or other
objects are situated between the bed-frame and the chassis.
1.10. Safety frames – Risk of entrapment
In the case of patients whose physical or mental state may be felt to call for the use
of safety frames to protect them from falling out of bed, the following safety
measures must be observed at all times:
1. Safety frames may be operated only by carers instructed in their use.
2. Make sure safety frames – or elements of them – are either fully raised and
locked or fully lowered.
3. During the electrical adjustment of the mattress-frame, make sure that the
patient is not
limbs are poking through the frames.
4. If the safety frames are being used to protect a child or a person whose physical
state may make their use appropriate, then make sure that the handset is out of
reach. We also recommend the use of safety frame covers.
Failure by carers to obey these safety rules may cause hæmatoma or other injury to
hands, knees, fingers, feet, shins and hips through entrapment.
touching the safety frames. Also make absolutely sure that no

1.12. Service and maintenance
The S 960-1 bed requires very little maintenance. All moving parts of the lifting gear,
mattress-frame drives and safety frames are permanently lubricated during
manufacture. None of these parts need relubrication when the bed is correctly used
and cleaned. The manufacturer assumes, however, that beds are regularly inspected
and damage such as worn parts, loose screws or fractures are immediately put right.
For further information, please see the maintenance section of this user’s manual.

Völker hospital bed User’s Manual Model S 960-1
repositioning of leg section. Full horizontal lower leg position possible by
putting upper leg section at 75°.
Mattress displacement device according to GPNA:
The mattress displacement device or length compensator automatically
shifts the fulcrum of the back section 15 cm backwards when it is being
raised. This stops patients sliding down the bed and concertinaing against
the footboard, especially when both back and leg sections are being
adjusted simultaneously. The compensator creates a kinæsthetic space that
stimulates patient mobility.
Fast-release facility:
The back section can be rapidly lowered (CPR) as required simply by
releasing the retaining mechanism on the mattress-frame. The facility is
fitted with a cushioning device to ensure jerk-free descent. No resetting is
needed to reinstate normal back section operation after fast release.
Safety frames:
The S 960-1 is equipped with split safety frames on both sides of the bed
that are fully integrated into the mattress-frame. When raised, they both
protect the patient and serve as a support when accessing or exiting the
bed. When not in use, they are pushed out of sight beneath the mattressframe. This facilitates the unobstructed fitting of accessories and the use of
a bed-jack even when the bed is in lowest position. During mattress-frame
adjustment, the safety frames are repositioned automatically. To use, pull
the safety frames horizontally out of their locations. To protect the patient,
they are then raised either singly or together and locked into position.
Complete patient protection is achieved by raising all four safety frame.
Thanks to their exceptional stability, they can also by used as a depository
for bedding or as support for special therapeutic positioning, eg
physiotherapy. This stability also stimulates patient mobility by providing
reliable support when sitting up and exiting the bed. As in the case of many
S 960-1 functional features, here too the variety of possible configurations
pays off. Hence the back section can be used to help the patient sit up, and
the telescopic jack to put the bed at the ideal individual height for exiting it.
As an option, the height of the safety frames can be increased by 12 cm, eg
when using special mattresses. In this way, the minimum required height of
22 cm between mattress and the upper edge of safety frames can always be
maintained. During transport, the safety frames – in whatever position – act
as robust anti-impact side-fenders. In the case of the S 960-1, this avoids
the usual damage to door-frames or to the safety frames themselves.
Lengthening the bed:
An extension piece mounted on telescopic slides enables the bed to be
lengthened by 20 cm without removing the footboard (optional). The
extension piece is securely fixed to the lower leg section of the mattressframe and is simply pulled out of its location and folded up, as required.
Edition: 2002 May.-C

Völker hospital bed User’s Manual Model S 960-1
Fast removal of head- and footboard:
The head- and footboard can be removed as required by means of a fastrelease fixing built into the bed-frame. Easy handling at all times is ensured
by the use of plastic connectors with an exceptionally long service life. As
the connectors are not subject to crevice corrosion, they do not split and
hence tend to clamp even after being washed many times.
Fixings for trapeze pole and drip-feed stands:
Push-in sleeves for trapeze poles and drip-feed stands are provided on the
outside of the headend of the bed.
Fixings for accessories and therapeutic appliances:
Adapters fitted to the full-length slide bars on each side of the bed accept
therapeutic appliances and care accessories. These can be positioned as
required simply by pushing them back and forth along the slide bar. Easy
positioning is guaranteed independently of bed height and safety frame
configuration.
Wall buffer wheels:
In addition to the safety frames acting as side-fenders during transport,
there are also horizontal buffer wheels on all corners of the bed and two
further vertical buffer wheels at the headend.
Accessories: Völker offers a wide range of accessories for its beds.
You will find the complete range in our hospital accessories brochure.

electrosmog.
Carers’ keyboard with all mattress-frame positions and height adjustment,
plus trendelenburg/reverse trendelenburg function, activation/deactivation
of patient’s handset functions, including graphic display. Functions that
stimulate the autonomous mobility of patients, ie height adjustment and
mattress-frame positioning, can be selected by patients themselves via
separate handset (unbreakable; IP X5 as standard or IP X6 for
decontamination plants).
Handset for patients with the following functions:
− Back section up/down

− Lower leg section up/down
− Height adjustment up/down
− Comfortable sitting position
Handset can be mounted to right or left, as required; an optional handset
connection is also available on safety frame.
Operational readiness independently of mains supply is ensured by means
of a rechargeable battery. An integrated power-saver (eco-mode) means
that the bed remains operational over long periods out of service. In normal
operation, the bed can be used for about 2 days with a fully-charged
battery. When used as instructed, the service life of the batteries is at least
5 years. Spent batteries are returned to Völker for recycling.
The use of an external 400 mA charger and an internal energy storage
device ensures that only safe low voltage current flows from the battery
charger (in the socket) onwards. The bed is fitted with an infrared port for
maintenance purposes
Cleaning: If required, a version of the bed can be supplied that is suitable for cleaning
in decontamination plants. Follow the recommendations in brochure ZH
1/200 to ensure a long service life and functional efficiency.

3. Explanatory notes for carers
This documentation contains all information necessary for the normal operation of
Völker hospital beds.
Völker accepts no guarantee claims whatsoever for damage, injury or accidents
caused by carelessness, inattentiveness or the incorrect use of the Völker hospital
bed. In this connection, the question of culpability is irrelevant.
If required by the customer, Völker or its representative is willing to give carers basic
training in the operation of the bed.
The participation in such training sessions for carers must be confirmed with name,
date and signature on a form specifically intended for this purpose, which must be
counter-signed by Völker or its representative.
The safety regulations contained in this documentation – more especially those in
Chapter 2 – must be strictly obeyed and adhered to at all times.
The conscientious observance of the safety regulations, modes of behaviour and
instructions described in this manual guarantees the safety of carers, patients and
others.
Please note that functional features marked as special equipment are only available
in beds so equipped.

5. Operational units
General operating instructions
5.1.1. Safety class
The bed conforms to Safety Class II and Type B according to DIN EN 60601-1 and VDE
0750, Part 1.
The bed is fitted with a connection for a voltage compensator.
The electricity supply via the charger is safety insulated and is equipped with a fail-safe
transformer that charges the battery with electrical energy.
5.1.2. Operating interval
The maximum operating interval of the electrically-powered bed functions is given on the
bed (name plate) and/or in the technical data sheet as “Int 2 min / 10 min”, ie each bed
function may only be continuously operated for a maximum of 2 minutes in any period of
10 minutes.
Automatic safety devices kick in if the maximum operating interval of 2
minutes is repeatedly or markedly exceeded, leading to the power drives
cutting out. The bed must then be inspected and tested!
An integrated time-lag device hinders the accidental or brief operation of the keyboard
and consequent movement of the mattress-frame. This device requires that users
consciously press and hold down the relevant key. Functions then kick in after a time-lag
of ca. 0.5 seconds.
5.1.3. Batteries
When fully charged, the bed batteries have a theoretical capacity sufficient to power all
bed functions with a working load of 170 kg continuously for ca. 15 minutes. After that,
only the emergency functions (trendelenburg/reverse trendelenburg) and booting can be
carried out.
If the bed is put into storage with disconnected charger, then self-discharge
through leakage leads to the exhaustion of the battery!
Totally discharged batteries can be so badly damaged as to necessitate their
premature replacement!
In order to achieve a long service life, the correct treatment of both the
battery and the charger is absolutely essential!
5.1.4. Built-in safety cut-out
The bed is fitted with a built-in electronic safety cut-out that hinders the overloading of
the drives. In the event of overloading, the drives are automatically switched off. For
safety reasons, thereafter electrical adjustment is only possible in the opposite direction.
This adjustment in the opposite direction is also required if the drive is
already in end-position!
After having been moved in the opposite direction, normal adjustment of the mattressframe is automatically reinstated.

Puting bed into service for the first time (initiation)
Location
The bed is authorised for use solely in dry rooms (Technical data sheet). A mains power
supply socket and, if required, a voltage compensator connection must be available in the
room in which the bed is to be used.
The bed is mobile without the need for auxiliary transport equipment.
The bed may only be moved on firm surfaces. Moving the bed over obstacles greater than
2 cm in height is prohibited. Gradiants may not exceed an angle of 10°.
The bed is supplied complete and can be set up without first having to remove transport
equipment.
5.2.1. Mechanical initiation
• Push the head- and footboards supplied into the corner connectors of the bedframe.
(see 5.3.10)
• Handset connection
There is a socket for the handset on the LH and RH face of the central bearer below
the seat section. Pull off the protective cap and insert the handset plug. Make sure
that the socket that is not in use always remains sealed with the protective cap!
If the handset is removed from the bed, then the socket must immediately be
resealed with the protective cap (maintenance of safety standards IP-X5 or IP X6).
