5.8.5 Supplementary heating (optional)
The supplementary heating (133/1) is located
on the left of the driver's cab. It heats the cab.
Any other use of the supplementary heating
and of the associated timer is not permitted.
The supplementary heating is connected di-
rectly to the fuel system, so that it can be op-
erated independently of the drive motor.
The supplementary heating is operated using
the operator device (132/32). Information
about the functions and the operation of the
supplementary heating can be found in the
operating instructions provided by the heater
manufacturer.
The blower for the air conditioning system is
switched off automatically when the supplemen-
tary heating system is switched on. To prevent
heat accumulation, the ejector (132/20) cannot
be closed in a cab with supplementary heating.
In the case of strong accumulation of dust,
change the air filter element every 100 operating
hours.
