Check the air cleaner daily or before starting the
engine. 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.
