2 Safety and fitting instructions
These safety instructions are intended to prevent accidents at work, and it is imperative that they
are observed.
2.1 Before any inspection or repair work
• Read and observe this repair manual and the associated operating manual!
• Observe the minimum requirements for carrying out the work (see chapter entitled " General
information)!
2.2 General safety information and information about fitting / removal
Danger of crushing!
• Please note the high weight of some components! This applies especially to removal of drive
units and batteries!
CAUTION: Injury hazard if the vehicle starts moving unintentionally during repair work!
• Switch the power supply off (ON/OFF key)!
• Engage the drive!
• Before jacking up, secure the vehicle by using chocks to block the wheels.
Fire and burn hazard due to electrical short-circuit!
• The mobility aid must be switched off before removal of voltage-carrying components! The
batteries must be removed to do this!
• When carrying out measurements on voltage-carrying components, avoid short-circuiting the
contacts! Fire and burn hazard!
Injury hazard and danger of damage to vehicle due to improper or incomplete
maintenance work!
• Use only undamaged tools in good condition.
• Some moving parts are mounted in sockets with PTFE coating (Teflon™). These sockets
must on no account be greased!
• Never use "normal" nuts instead of self-locking nuts!
• Always use correctly-dimensioned washers and spacers!
• Cable ties which have been cut during removal must be replaced during refitting!
• After completing your work / before renewed start-up of the mobility aid, check all
connections for tight fitting. Check all parts for correct interlocking.
• Only operate the vehicle with the approved tyre pressures (see technical data)!
• Check electrical components for correct functioning - incorrect polarity can result in damage
to the electronic system!
• Always carry out a trial run when your work is finished!
Note
Mark all current settings for the mobility aid (seat, armrests, backrest etc.), and the associated
cable connecting plugs, before dismantling. This makes reassembly easier.
All plugs are fitted with mechanical safety devices which prevent release of the connecting plugs
during operation. To release the connecting plugs the safety devices must be pressed in. When
reassembling ensure that these safety devices are correctly engaged.
