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 Personal safety equipment
Safety shoes
The mobility device, and some of its components, are very heavy. These parts can result
in injuries to the feet if they are allowed to drop.
•Wear standardised safety shoes during all work.
Eye protection
It is possible that battery acid can be discharged when working on defective batteries or
when handling batteries improperly.
•Always wear eye protection when working on any defective or possibly defective batteries.
Safety gloves
It is possible that battery acid can be discharged when working on defective batteries or
when handling batteries improperly.
•Always wear acid-proof safety gloves when working on any defective or possibly defective
batteries.
2.3 General safety information and information about fitting / removal
WARNING: Danger of crushing!
Various components such as the drive unit, batteries, seat etc are very heavy. This results
in injury hazards to your hands!
•Please note the high weight of some components! This applies especially to the removal of
drive units, batteries and the seat.
WARNING!
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.
ATTENTION!
Fire and burn hazard due to electrical short-circuit!
•The mobility device must be completely switched off before removal of voltage-carrying
components! To do this, remove the batteries.
•Avoid short-circuiting the contacts when carrying out measurements on voltage-carrying
components!

SERVICE MANUAL
Invacare®- Kite
14
CAUTION!
Danger of burns from hot surfaces on the motor!
•Allow the motors to cool down before commencing work on them.
ATTENTION!
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™). Never grease these
sockets!
•Never use "normal" nuts instead of self-locking nuts.
•Always use correctly-dimensioned washers and spacers
•When reassembling, always replace any cable ties which were cut during dismantling.
•After completing your work / before renewed start-up of the mobility device, check all
connections for tight fitting.
•After completing your work / before renewed start-up of the mobility device, check all parts for
correct locking.
•Only operate the vehicle with the approved tyre pressures (see technical data).
•Check all electrical components for correct function. Please note that incorrect polarity can
result in damage to the electronics.
•Always carry out a trial run at the end of your work.
CAUTION!
Danger of injury and damage to property, if the maximum speed reduction on a
wheelchair with a lifter does not function correctly!
The wheelchair’s control unit must reduce the maximum possible speed as soon as the
lifter is raised.
•Test the maximum speed reduction for correct function after any maintenance work or
modifications to the wheelchair.
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.
CAUTION!
Any changes to the drive program can affect the driving characteristics and the tipping
stability of the vehicle!
•Changes to the drive program may only be carried out by trained Invacare® specialist
dealers!
•Invacare® supplies all mobility aids with a standard drive program ex-works. Invacare® can
only give a warranty for safe vehicle driving behaviour - especially tipping stability - for this
standard drive program!
