1. Stop the engine and let the muffler become cool.
2. Remove the muffler cover.
3. If the muffler on your product has a spark arrester
screen, do these steps:
a) Do a visual check. Replace the spark arrester
screen if it is damaged.
b) Clean the spark arrester screen if it is blocked.
Clean weekly if your product has a catalytic
converter. Clean monthly if your product does not
have a catalytic converter.
CAUTION: A blocked spark arrester
screen causes the engine to become too
hot which causes damage to the engine.
CAUTION: If the spark arrester screen is
frequently blocked, it can be a sign that
performance of the catalytic converter is
decreased. Speak to your servicing dealer to
examine the muffler. A blocked spark
arrester screen causes overheating and
results in damage to the cylinder and piston.
