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

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.
• 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.

WARNING
To avoid serious injury or death:
• Be sure to stop the engine and remove the key
before changing the oil.
• Allow the engine to cool down sufficiently, as
oil can be hot and may cause burns.
1. To change the used oil, use the oil 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.
NOTE :
• The used oil can be drained out more easily
if the engine is warm.
