Warning to all operators in California
A
Under California law, and under the laws of several other states, it is not lawful to operate an internal combustion engine using
hydrocarbon fuels on any forest covered, brush covered, or grass covered land, or on land covered with grain, hay, or other
flammable agricultural crop, without an engine spark arrester in continuous effective working order.
The engine on this unit, like most outdoor power equipment, is an internal combustion engine that burns gasoline, a
hydrocarbon fuel. Therefore, this unit must be equipped with a spark arrester muffler in continuous effective working order. The
spark arrester must be attached to the engine exhaust system in such a manner that flames or heat from the system will not
ignite flammable material. Failure of the owner/operator of this unit to comply with this regulation is a misdemeanor under
California law, and may also be a violation of other state and/or federal regulations, laws, ordinances, or codes. Contact the
local fire marshal or forest service for specific information about which regulations apply in your area.
and other applicable states.
