Periodic Maintenance and Adjustment 8-25
WARNING
Never operate an engine without the air filter
element installed. This will allow unfiltered air
to enter, causing rapid engine wear and
possible engine damage. Additionally,
operation without the air filter element will
lower the performance of the engine and the
engine may overheat.
Spark arrester cleaning
Be sure the exhaust pipe and muffler have
cooled down before cleaning the spark
arrester.
1. Remove the bolts.
2. Remove the tailpipe and the spark
arrester by pulling it out of the muffler.
3. Tap the exhaust pipe lightly, and then
use a wire brush to remove all carbon
deposits from the spark arrester portion
of the exhaust pipe and inside of the
exhaust pipe housing.
4. Insert the exhaust pipe into the muffler
and align the bolt holes.
5. Install and tighten the bolts.
