hot. Severe thermal burns can occur on contact. Combustible debris, such as leaves,
grass, brush, etc. can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
• Contact the original equipment manufacturer, retailer, or dealer to obtain a spark arrester
designed for the exhaust system installed on this engine.
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler for cracks,
corrosion, or other damage. Remove the spark arrester, if equipped, and inspect for damage or
carbon blockage. If damage is found, install replacement parts before operating.
CAUTION! A
Replacement parts must be of the same design and installed in the same position as
the original parts. Other parts may not perform as well, may damage the unit, and
may result in injury.
