Heater radiator
The heater radiator (1) is fitted in a housing under
the cab seat for central displacement of warm or cold
air flow.
IMPORTANT: to ensure a good flow of air through
the heater radiator the filter should be cleaned more
frequently when operating in extremely dusty condi-
tions.
Air flow vents
Air flow vents are connected to the heater container
and receive air from the blower motor, to direct warm
or cold air onto the windscreen and side windows or
to the cab interior as required.
Each vent may be swivelled and adjusted to control
the flow of air.
To open a vent, press one side of the disc and turn
it, as required, to direct the air flow.
The vents are located as follows:
- two on the top of the front control panels (A);
- two to the rear of the seat (C);
- two under the seat, one in front, the other on the
rear (D);
- two on the cab posts, right and left (B);
- two on the ceiling, in front and back of operator's
head (E).
NOTE: the vents (B) and (E) are mounted only when
air conditioning (optional) is fitted.
