MAINTENANCE

Spark Arrester

WARNING
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 operate without the spark arrester.
• 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. A
plugged spark arrester will affect engine performance. Clean daily when
driving in mud and water. Replace a cracked or damaged arrester before
operating.
1. Remove the arrester
retaining bolt and nut.
2. Remove the arrester
from the end of the
muffler.
3. Use a non-synthetic
brush to clean the
arrester screen. A syn-
thetic brush may melt if
components are warm.
If necessary, blow
debris from the screen
with compressed air.
4. Inspect the screen for
wear and damage.
Replace a worn or damaged screen.
5. Reinstall the arrester. Torque bolt to 9-11 ft. lbs. (12-15 Nm).
