Spark Arrester

WARNING
Failure to heed the following warnings while servicing the spark arrester could
result in serious injury or death. Never run the engine in an enclosed area.
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 go under the vehicle while it's inclined.
The exhaust system can get extremely hot. Do not perform service on the spark
arrester while the system is hot. Allow components to cool sufficiently before
proceeding.
Use the following procedure to periodically purge accumulated carbon
from the exhaust pipe/muffler.
1. Remove the arrester clean-out plug
from the bottom of the muffler. Be
sure to clean out both arresters if
your model has two.
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 to 6 until no more particles are expelled.
9. Stop the engine. Allow the arrester to cool.
10. Reinstall the arrester plug and remove the exhaust outlet cover or
plug.
