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 unfiltered
air into the engine causing premature wear
and failure.
Air Filter

filter may be clogged. If running with a dirty air filter,
the spark plugs can become fouled.
For this reason, it is important to replace the air filter
regularly (see the heading Maintenance Schedule for
the proper service interval).
IMPORTANT INFORMATION

filter.
