CLEANING THE AIR FILTER
For proper performance and longer life, keep the foam air
filter clean.
■ Remove the air filter cover by pushing down on the
latches while gently pulling off the cover.
■ Remove the air filter.
■ Clean the foam filter element with warm, soapy water.
Rinse and let dry.
NOTE: If the foam lter element is damaged, it should be
replaced.
■ Apply a light coat of engine oil to the foam filter element,
then squeeze it out.
■ Reinstall the air filter.
NOTE: Make sure the lter is seated properly inside the
cover. Installing the lter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
■ Replace the air filter cover by placing the slots on the air
filter cover over the latches on the housing, then push
the cover down until it snaps securely in place.
CHECKING THE FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable lter and a check
valve. A clogged fuel lter causes poor engine performance.
If performance improves when the fuel cap is loosened, the
valve may be faulty or the lter may be clogged. Replace
the fuel cap if necessary.
