CAUTION: The spark arrestor screen must
be replaced if it is damaged. Do not use a
product without, or with a broken, spark
arrestor screen if you must have a spark
arrestor screen in your area. Obey local
regulations and maintenance instructions.
CAUTION: If the spark arrestor screen is
frequently blocked it can be a sign that the
performance of the catalytic converter is
decreased. Turn to your servicing dealer to
examine the muffler. A blocked spark
arrestor screen will cause overheating and
result in damage to the cylinder and piston.

• Air intake on the starter.
• Flywheel fins on the flywheel.
• Cooling fins on the cylinder.
• Cylinder cover (points cool air over the cylinder).
• Muffler cover.
• Muffler plate.
