MAINTENANCE
Spark Arrestor
Occasionally, the spark arrestor may accumulate carbon, which can
restrict the exhaust if left unattended. Purge the spark arrestor.
1. Position the vehicle on a level
surface.
2. Place the transmission in PARK.
3. Remove the arrestor
clean-out plug from the
bottom of the muffler.
4. Start the engine.
5. Quickly squeeze and
release the throttle lever
several times to purge car-
bon from the system.
6. If carbon comes out of the exhaust, cover or plug the exhaust outlet.
Wear protective gloves.
7. Lightly tap on the exhaust pipe with a rubber mallet while repeating
step 5.
8. If particles are still suspected to be in the muffler, elevate the rear of
the vehicle 30 cm higher than the front. Block the wheels.
9. Place the transmission in PARK. Repeat steps 5 to 7 until no more
particles are expelled.
10. Stop the engine. Allow the arrestor to cool.
11. Reinstall the arrestor plug and remove the exhaust outlet cover or
plug.
WARNING
Allow components to cool sufficiently before servicing. The exhaust system
can get extremely hot. Never run the engine in an enclosed area or indoors.
Exhaust contains poisonous carbon monoxide gas. Never go under the
vehicle while it's inclined.
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.
