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!

maximum speed reduction on a mobility device

The mobility device's control unit must reduce
the maximum possible speed as soon as the lifter

function after any maintenance work or
modifications to the mobility device.
