8-27 Periodic Maintenance and Adjustment
11. Install the air filter case cover and be sure
to connect the hose.
12. Install the seat.
NOTE:
The air filter element should be cleaned
every 20-40 hours. It should be cleaned and
lubricated more often if the machine is
operated in extremely dusty areas. Each time
air filter element maintenance is performed,
check the air inlet to the air filter case for
obstructions.
Check the air filter element rubber joint to the
carburetor and manifold fittings for an airtight
seal. Tighten all fittings securely to avoid the
possibility of unfiltered air entering the
engine.
CAUTION:
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally,
operation without the air filter element will
affect carburetor jetting with subsequent poor
performance and possible engine
overheating.
Spark arrester cleaning
Be sure the exhaust pipe and muffler are
cool before cleaning the spark arrester.
1. Remove the bolts.
2. Remove the tailpipe by pulling it out of
the muffler.
3. Tap the tailpipe lightly, and then use a wire
brush to remove any carbon deposits from
the spark arrester portion of the tailpipe and
inside of the tailpipe housing.
4. Insert the tailpipe into the muffler and
align the bolt holes.
5. Install and tighten the bolts.
