MAINTENANCE
Replacing Air Filter
The engine is equipped with a replaceable, high
density paper air cleaner element and an oiled, foam
precleaner which surrounds the paper element.
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.
IMPORTANT INFORMATION
Operating the engine with loose or
damaged air cleaner components could
allow unltered air into the engine causing
premature wear and failure.

lter may be clogged. If running with a dirty air lter,
