EMISSION INFORMATION
WARNING
WARNING TO ALL CALIFORNIA
AND OTHER STATES OPERATING
OUTDOOR POWER EQUIPMENT
Under California Law and under the
laws of several other states you are
not permitted 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 your power equipment,
like most outdoor power equipment,
is an internal combustion engine that
burns gasoline, a hydrocarbon fuel.
Therefore, your power equipment
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.
M-F, 8 a.m. to 5 p.m.
Central Time
Failure of the owner/operator of the
equipment 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 your local fire
marshal or forest service for specific
information about what regulations
apply in your area.
The standard muffler installed on the
engine is not equipped with a spark
arrester. One must be added before
use if this machine is intended to be
used in an area where a spark
arrester is required by law. Contact
the local authorities if these laws
apply to you. See your authorized
engine dealer for spark arrester
options.
