Check for a buildup of dirt and debris around the air
cleaner system. Keep this area clean. Also check for
loose or damaged components. Replace all bent or
damaged air cleaner components.
Note: Operating the engine with loose or damaged air
cleaner components could allow unfiltered air
into the engine causing premature wear and
failure.
Precleaner Service

wring). Allow the precleaner to air dry.

Squeeze out all of the excess oil.
