Exhaust System Warnings
WARNING
Running engines produce heat. Engine parts, especially
mufflers, become extremely 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.
• It is a violation of California Public Resource Code,
Section 4442, to use or operate the engine on any
forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark
arrester, as defined in Section 4442, maintained in
effective working order. Other states or federal
jurisdictions may have similar laws. Contact the original
equipment manufacturer, retailer, or dealer to obtain a
spark arrester designed for the exhaust system installed
on this engine.
WARNING
Replacement parts must be the same and installed in the
same position as the original parts or fire could result.
