Operating the heating system (cab version)
!
Open the engine compartment cover (page 107).
!
Open heater valve (1) by turning against the clock.
!
Close the engine compartment cover.
!
Start the engine (page 68).
!
Set the blower switch to position LO or HI.
!
To heat the cab faster, switch aerial supply to position circula-
ting air (2) with lever (1).
No cold outside air will follow and the circulating inside air heats
faster.
So that the windows do not steam up at longer operation of the heat-
er, the aerial supply should be switched back to position "fresh air"
(3) after the warm-up phase of the cab is complete.
The heater valve should be always closed in summer.
All activities described below and required for operating the heater must be carried out with engine
running.
To avoid accumulated heat and damage to the ventilation system, do not cover air nozzles with ob-
jects (e.g. bags or clothes) when the heater is on.
In dusty surroundings, the fresh air supply should be
switched on in order to increase the air pressure inside
the cab. This contributes to the fact that no dust pene-
trates into the cab.
