SAFETY
1.1 SAFETY ALERT SYMBOL 1.2 EMISSION INFORMATION
Under California
Law and 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
The Owner/Operator’s manual uses this symbol to alert
you of potential hazards. Whenever you see this symbol,
read and obey the safety message that follows it. Failure
to obey the safety message could result in personal injury,
death or property damage.
DANGER
Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.
WARNING
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
land or on land covered with grain, hay or other ammable
agricultural crops, 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 or diesel fuel (hydrocarbons). Therefore,
your power equipment must be equipped with a spark
arrester mufer in continuous effective working order. The
spark arrester must be attached to the engine exhaust
system in such a manner that ames or heat from the
system will not ignite ammable material.
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 re marshal or forest service for specic information
about which regulations apply in your area.
ENGLISH
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury.
WHEELED TRIMMER
The standard mufer installed on the engine is not equipped
with a spark arrester. One must be added before using
this machine 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.
