MAINTENANCE
Spark Arrestor
WARNING
Failure to heed the following warnings while servicing the spark
arrestor could result in serious injury or death.
Do not perform service on the spark arrestor 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 leather work 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.
Never go under the vehicle while it’s inclined.
1. Remove the arrestor clean-out
plug (1) from the bottom of the
muffler.
2. Place the transmission in PARK.
3. Start the engine.
4. Quickly squeeze and release the
throttle lever several times to
purge carbon from the system.
5. If carbon comes out of the exhaust,
cover or plug the exhaust outlet. Wear
protective gloves.
6. Lightly tap on the exhaust pipe with a rubber mallet while
repeating step 4.
7. If particles are still suspected to be in the muffler, elevate the rear
of the vehicle one foot (30 cm) higher than the front. Block the
wheels.
8. Place the transmission in PARK. Lock the parking brake. Repeat
steps 4-6 until no more particles are expelled.
9. Stop the engine. Allow the arrestor to cool.
