General Safety Information and Information About Fitting
/ Removal
DANGER!
Risk of Death, Serious Injury, or Damage
Lighted cigarettes dropped onto an upholstered
seating system can cause a fire resulting in
death, serious injury, or damage. Mobility
device occupants are at particular risk of death
or serious injury from these fires and resulting
fumes because they may not have the ability to
move away from the mobility device.
– DO NOT smoke while using this mobility
device.
WARNING!
Risk of Serious Injury or Damage
Storing or using the mobility device near open
flame or combustible products can result in
serious injury or damage.
– Avoid storing or using the mobility device
near open flame or combustible products.
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 mobility device starts
moving unintentionally during repair work
– Switch the power supply off (ON/OFF key).
– Engage the drive.
– Before lifting up, secure the mobility device
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 mobility
device 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 mobility device with the
approved tyre pressures (see technical data).
– Check all electrical components for correct
function. Note that incorrect polarity can
result in damage to the control system.
– 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.
