1.0 Safety and installation instructions
The safety instructions are provided in the interests of working safety and must under all circumstances be
complied with.
Prior to all inspection and repair work:
• Read this service manual and the appertaining user manual.
• Ensure that minimum qualifications for performing relevant work are fulfilled (see chapter entitled “General
information”).
Caution:
• Note that some components are heavy. You should take this into account above all when removing
the batteries.
• The power supply for the wheelchair must be switched off before any conductive parts are removed.
Remove the batteries.
• When performing tests on conductive parts, ensure that the contacts are not short-circuited.
> Danger of fire and injury from burns <
• Only use tools which are in perfect working order and are not damaged.
During work and assembly:
• Mark the current settings of the wheelchair (seat, armrests, back etc.) and the combination of cable connec-
tions before carrying out disassembly work. This will make assembly an easier task afterwards.
ACHTUNG:
• Support the raised wheelchair with suitable supports before you begin assembly. Use the bottom tube
. frames of the chassis. Also see the illustration G40, bottom view, chapter 6.0.
• You should under no circumstances use “normal” nuts instead of self-locking nuts.
• Always use correctly-sized washers or separators.
Note:
• All plug connectors are fitted with mechanical clamps which prevent slipping when the wheelchair is in
operation.
• These clamps must be pressed in to release the connectors.
• When carrying out assembly work, ensure that the clamps are fitted properly.
• For checks and repair works you can fold up the seat system and arrest. This position is called
service position.
Prior to initial use / after repair work:
Caution:
• Check firm mounting of all fastening screws.
• Check that all parts are properly locked in place.
• Check regulation tyre pressure (2.5 bar) before starting the machine.
• Always perform a test-drive after repair work.
