AIR CLEANING SYSTEM
AIR CLEANER HOODS (1, lIIust. 1)
The dome of the air cleaner servesas a rain shield, and the
screenpreventschaff and coarsedirt from getting into the air
cleaner. Keep this screen clean from all chaff, oil or dust.
Clogged holes in the screen will reduce the power of the
engine by restricting the flow of air.
Loosen the clamp screw on the hood and remove it by
twisting and pulling upward. Use compressedair to clean the
screen. If compressed air is not available, wash in clean hot
water or preferably water containing a small amount of
nonsudsing detergent. Install the hood back in place and
tighten the clamp.
Dust Unloader Valve (12, lIIust. 1)
The valve automatically dischargesthe accumulated dirt in
the air cleaner body. At the interval specified on the
"SCHEDULED

squeezeor remove the valveto be sure it is open and contains
no obstructions.

cated outside the cab on the right side. This filter must be
cleaned when the cab pressurizeror heater (if equipped) is in
use. Under normal conditions, the filter will require cleaning
every 10 hours of use. If the conditions are very dusty, the
filter will require cleaningmore often. A clean filter is required

to turn the air conditioning temperature control to the
