Air Cleaner
Inspection of Air Cleaner
The air cleaner is a component that removes
dirt from the intake air to prevent wear of the
cylinder liners and piston rings so that the
engine will always operate smoothly.
A contaminated air cleaner element may
cause malfunction of the engine.
Inspect the air cleaner by checking the
evacuator valve.
If the air cleaner element is contaminated,
the evacuator valve will display a red ring.
