5.1 General Warning Information on
Installation Work
CAUTION!
Risk of damage to vehicle
Collisions can be caused if the adjusting washers
are removed during fitting work to the drive
wheels. Adjusting washers are often fitted
between the drive shaft and the wheel hub to
even out tolerances. If these adjusting washers
are removed and not replaced again, collisions
can be caused.
– Always replace the adjusting washers exactly
as they were before you started dismantling.
CAUTION!
Risk of injury and damage to property, if
the maximum speed reduction on a mobility
device with a lifter does not function correctly
The mobility device’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 mobility device.

Carry out the necessary checks and repairs as
recommended in the following table.
The various power modules can be fitted in connection
