55 Maintenance
The following are detailed instructions for
performing routine maintenance procedures on
the air cleaner.
Raw, unfiltered air can damage the
roller. Never service the air cleaner
while the roller is running.
Airborne dust may be hazardous. Wear
proper personal protective equipment
while handling air cleaners and
elements.
Air Cleaner Indicators
Check the air cleaner visual restriction indicator
before and after every shift.
If the indicator on the air cleaner turns red, replace
the main filter on the air cleaner. The dust pouch
is emptied by pressing the rubber bellows with
your fingers. Check also that the air hoses are in
good condition. Clean the air cleaner when
operated in extremely dusty environments.
Connections and Ducts
Check air cleaner and ducts for leaks before every
shift, during every shift, and after every shift. Make
sure all connections between the air cleaner and
air compressor are tight and sealed.
Note
Dust that gets by the air cleaner
system can often be detected by
looking for dust streaks on the air
transfer tubing or just inside the intake
manifold inlet.
Wipe clean the inside of the cover and the filter
housing. Wipe also both surfaces for the outlet
pipe.
Not e
Check that the hose clamps between the
filter housing and the suction hose are
tight and that the hoses are intact.
Inspect the entire hose system, all the
way to the engine.

Never clean Donoclone tubes with
