– Clean the sensor glass of the LED height
sensor (1) and reflector (2) with a soft
microfibre cloth and water. A small amount
of cleaning agent can be added to the water.
Elimination of malfunctions by the driver
NOTE
A misaligned sensor or bent reflector must be
adjusted only by the authorised service centre.
The driver can resolve a temporary interrup-
tion of the light signal due to contamination
or foreign objects in the signal path. If the
malfunction in the system still exists, please
contact the authorised service centre.
In the event of a malfunction, an error num-
ber is shown in the display. The system is
automatically available again as soon as the
malfunction is no longer present or has been
rectified.
Truck functions that are dependent on the
lift height are restricted in the event of a
malfunction in the height measurement.
The malfunctions must therefore be rectified
immediately.
