MAINTENANCE
Spark Arrester
Failure to heed the following warnings while servicing the spark arrester could result in serious injury or
death.
• Do not perform service on the spark arrester while the system is hot. Exhaust system temperatures
can reach 1000° F. Allow components to cool sufficiently before proceeding.
• Remove any combustible materials from the area.
• Wear eye protection and gloves.
• Do not stand behind or in front of the vehicle while purging.
• 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.
• Never go under the vehicle while it's inclined.
Use the following procedure to periodically purge accumulated carbon from the exhaust
pipe.
1. Remove the arrester clean-out plug located
on the bottom of the muffler.
2. Place the transmission in PARK.
3. Start the engine.
4. Purge accumulated carbon from the system
by momentarily revving the engine several
times.
5. If carbon is expelled, cover or plug the
exhaust outlet and rap on the pipe around the
clean-out plug while revving the engine sev-
eral more times.
6. If particles are still suspected to be in the muffler, elevate the rear of the vehicle one foot
higher than the front. Block the wheels.
7. Repeat steps 4 and 5 until no more particles are expelled when the engine is revved.
8. Stop the engine. Allow the arrester to cool.
9. Reinstall the arrester plug and remove the outlet cover or plug.
