Before commencing maintenance work

The service manual must be read in full by the person responsible for carrying out the servicing before starting the work.

Before commencing maintenance or repair work, the personnel responsible must be familiarised in detail with how to handle the bed and their attention must be drawn to the individual hazards described in this manual during assembly and disassembly of the bed's components.

The bed is not protected against explosion and must therefore only be serviced in an environment free from flammable substances and materials.

WARNING Before carrying out repair work, always pull out the mains plug and disconnect the bed from the battery pack by pressing the green reset button on the dual drive!

WARNING Maintenance and repair work should only be carried out after the bed has been disinfected.

WARNING Maintenance and repair work should only be carried out on an unoccupied bed. The patient may also have to be transferred to another bed before the work.

General regulations

The bed must only be operated and used in accordance with its designated purpose, in line with the conditions of the Medical Products Directive (MPG) and approved legislation pursuant to this, the generally-acknowledged rules of technology and the stipulations

of occupational safety and accident protection guidelines. The bed may not be operated in a faulty state that could endanger the patient, care staff or third parties.

The technical check  145 must be carried out at least once a year and after every lengthy period of non-use.

Any discernible damage, such as signs of wear and tear, loose screws or breaks/fractures must be eliminated immediately.

Use of securing systems

Securing systems such as belts or straps should only be used exactly as specified by the manufacturer.

If securing systems in the form of abdominal belts are used, then it must be ensured that the side rails are completely raised. In this case, the gap in the middle of the rails must be closed using a rail spacer.

DANGER When using securing systems and rail spacers, please note the separate instructions for use pertaining to these accessories.

If the patient is restrained with the help of restraint holders, the lying surfaces must never be adjusted while the patient is restrained and must always be in the lowest position!

The lying surface adjustment functions must be locked when a patient is secured, and the hand control must be kept out of the patient's reach!

Restraints may be fastened directly onto beds built after 08/2009.

To do this, fasten the restraints on the corresponding longitudinal section of the lying surface frame. Make sure that the restraint is passed between the mattress holder and the mattress.

Initial startup

The lnitial startup section describes how the bed is first set up.

On-time

The maximum On-time for the electromotive bed functions is specified on the bed (type label  160) or in the technical data sheet.

4 min./10 min. means that each electromotive adjustment may be operated for a maximum of 4 minutes, after which a pause of 10 minutes is necessary (protection against overheating).

NOTE Should the maximum Ontime of 4 minutes be exceeded repeatedly or for longer periods, safety cut-out devices on the bed may cause the electromechanical motor system to shut down. The bed must not be manoeuvred using the motors until it has cooled down sufficiently!

Battery pack

The battery pack integrated in the double drive has a charge capacity that allows in theory a constant operation of 10 lifting and lying surface adjustments with a working load of 250 kg.

NOTE If the bed is parked at its location and the mains plug is not connected, this will cause the battery pack to discharge due

to the buffering of the electronic components!

Deep-discharged battery packs can be damaged to the extent that premature replacement is needed!

To increase the stand-by time, it is recommended to activate the reset button on the housing when storing the bed and to disconnect the bed from the mains. The bed should not be stored for a period longer than 6 months with a fully charged battery pack without recharging it.

Appropriate and correct use of the battery pack is essential for it to have a long service life!

In order to guarantee electrical functionality at all times, the bed should be connected to the mains as much as possible.

Safety cut-out device

The bed is equipped with an electrical, self-resetting safety cut-out device that prevents overloading of the motor systems. In the event of very severe overloading, the bed is automatically switched off.
