General safety information and information about
fitting / removal
CAUTION!
Risk of crushing
Various components such as the drive unit, batteries,
seat etc are very heavy. This results in injury hazards to
your hands.
– Note the high weight of some components. This
applies especially to the removal of drive units,
batteries and the seat.
CAUTION!
Injury hazard if the vehicle starts moving
unintentionally during repair work
– Switch the power supply off (ON/OFF key).
– Engage the drive.
– Before lifting up, secure the vehicle by using chocks
to block the wheels.
CAUTION!
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.

CAUTION!
Risk of burns from hot surfaces on the motor
– Allow the motors to cool down before commencing
work on them.
CAUTION!
Injury hazard and risk 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 tire
pressures (see technical data).
– Check all electrical components for correct function.
Note that incorrect polarity can result in damage to
the electronics.
– Always carry out a trial run at the end of your work.
CAUTION!
Risk 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.
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 devices with a standard
drive program ex-works. Invacare can only give a
warranty for safe vehicle driving behavior - especially
tipping stability - for this standard drive program.
Mark all current settings for the mobility device (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.
