The effectiveness of the air con-
ditioning system can be increased
by selecting the most suitable
vent.
Do not turn the fan switch on
when all the vents are closed.
*
If the outside air is extremely
dusty, set the fan switch to the H
position. This will pressurize the
cab and prevent the dust from
entering.
