8. SPARK ARRESTER
In a dry or wooded area, it is recommendable to use the engine with a spark arrester. Some areas require the use of a spark
arrester. Please check you local laws and regulations before operating your engine.
The spark arrester must be cleaned regularly to keep it functioning as designed. A clogged spark arrester:
• Prevents the flow of exhaust gas
• Reduces engine output
• Increases fuel consumption
• Makes starting difficult
If the engine has been running, the muffler and the spark arrester will be very hot. Allow the muffler to cool before cleaning the
spark arrester.
How to remove the spark arrester
1. Remove the flange bolts from the muffler cover and remove the muffler cover.
2. Remove the special screw from the spark arrester and remove the spark arrester
from the muffler.
Clean the spark arrester screen
Use a brush to remove carbon deposits from the spark arrester screen. Be careful to
avoid damaging the screen. The spark arrester must be free of breaks and holes.
Replace the spark arrester if it is damaged.
