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 unltered air into the engine causing
premature wear and failure.
Air Filter Maintenance
If the engine seems weak or runs unevenly, the air
lter may be clogged. If running with a dirty air lter,
the spark plugs can become fouled.
For this reason, it is important to replace the air lter
regularly (see the heading Maintenance Schedule for
the proper service interval).
WARNING!
The engine and the exhaust
system become very hot during
operation. Risk for burns if
touched.
Allow engine and exhaust system
to cool at least two (2) minutes.
IMPORTANT INFORMATION
Do not use compressed air to clean the air
lter.
