MAINTENANCE
Spark Arrester
Failure to heed the following warnings while servicing the spark arrester could
result in serious injury or death.
Do not perform clean-out immediately after the engine has been run, as the
exhaust system becomes very hot. Serious burns could result from contact with
the exhaust components. Allow components to cool sufficiently before
proceeding.
Wear eye protection and gloves.
Never run the engine in an enclosed area. Exhaust contains poisonous carbon
monoxide gas that can cause loss of consciousness or death in a very short
time.
Periodically clean the spark arrester to remove accumulated carbon.
1. Remove the retaining nut. Remove the arrester from the end of the
muffler.
2. Use a non-synthetic brush to clean the arrester screen. A synthetic
brush may melt if components are warm. If necessary, blow debris
from the screen with compressed air.
3. Inspect the screen for wear and damage. Replace a worn or dam-
aged screen.
4. Reinstall the arrester. Torque the nut to 5-7 ft. lbs. (7-9 Nm).
