CAB (fig. K14) Fresh-air Fan Provides Good
Ventilation
The 4-speed fan is started using switch A. To change
the airflow direction, turn nozzles 1 at the front top
of the cab. Air coming into the fan is taken through
detachable coarse mesh and fine filters.
To keep up the fan capacity and to secure the purity
of the air, the filters have to be cleaned daily and
replaced often enough to prevent harmful impurities and
fungi from clogging the filters. In dusty conditions it is
necessary to clean the coarse mesh filter several times
a day.
By opening nozzles 2, cab indoor air can be circulated
through the fan, which reduces the need for outdoor air
and thus reduces the risk of blocked filters.
The windscreen wiper is controlled by switch B.
Cover D can be removed and a radio set installed in the
space.
HEATER Provides Additional Heat from the Engine
The air in the cab is heated by a heating element in
which the engine coolant circulates. Turn switch E to the
right to increase the amount of coolant circulating in the
element. This will increase the temperature in the cab.
Open nozzles 2, fig. K14, to re-circulate the heated cab
air. This will further increase the temperature in the cab.
AIR CONDITIONER Cools the Air in the Cab
The cab can be equipped with an air conditioner
system.
Turn switch C to the right to switch on and regulate the
cooler. Open nozzles 2 to re-circulate the cooled cab
air, which will further cool down
the cab.
Note! A difference of over 8
o
C between indoor and
outdoor temperatures is harmful to your health.
Keep the cab door closed when the air-conditioning is
on.
