Checking Muffler and Spark Arrester (if
equipped)
The muffler and spark arrester should be checked every
50 hours operation or every 1 year, whichever comes first.
Running engines produce heat. Engine parts,
especially muffler, become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush,
etc. can catch fire.
To avoid serious injury:
A
Allow muffler, engine cylinder and fins to cool
before touching.
A
Remove accumulated debris from muffler area
and cylinder area.
A
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.
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.
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.

A
Allow engine to cool down sufficiently; oil can
be hot and may cause burns.
1. To change the used oil, use the drain valve connected
to the engine block. To drain the oil, loosen the hex
plug until oil begins to drain. Then, remove the oil level
dipstick to allow the engine to vent.
