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 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. Start the
engine.
3. Press the brake pedal and then press the treadle
pedal to increase engine RPM. Purge
accumulated carbon from the system by
momentarily revving the engine several times.
4. If carbon is expelled, partially cover the
exhaust outlet and rap on the pipe around the
clean-out plug while revving the engine several
more times.
5. 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.
6. Repeat steps 3 and 4 until no more particles are expelled when the engine is revved.
7. Stop the engine. Allow the arrester to cool.
8. Reinstall the arrester plug and remove the partial outlet cover.
