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.
1533060-M
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.
