from electric motors and other electrical appliances,
DANGER
SPARK/FIRE HAZARD
GAS ENGINES MAY REQUIRE
A SPARK ARRESTER FOR SAFE OPERATION
If the engine on this unit is not equipped with a
spark arrester and is to be used on any forest,
brush, or grass-covered unimproved land, a
spark arrester must be added to the muffler
before using the engine on such land. The
arrester must be maintained in effective working
order by the operator. In the State of California,
the above is required by law (Section 4442 of the
California Public Resources Code.) Other states
may have similar laws. Federal laws apply on
federal lands. See your authorized engine service center for muffler spark arrester options.
or unattended smoking materials. Contact with these
or any other ignition sources will cause an explosion
or fire, serious personal injury, and damage to property and equipment.
9. Never overfill the fuel tank. Fuel may run out of the
tank and contact hot surfaces on the chipper/shredder motor and ignite, causing a fire and/or risk of an
explosion. Fill fuel tank to 1/2” below bottom of filler
neck only.
10.Use only an approved container for fuel and always
handle the container with extreme care. Never smoke
while fueling the chipper/shredder or transporting the
fuel container.
11.Never store the fuel container or chipper/shredder
indoors where there is a possibility of contact with
any ignition source such as a spark, open flame, pilot
light, heating element, or smoking materials.
12.Never attempt to operate a unit indoors or in an
enclosed area. Engine exhaust contains Carbon
Monoxide, an odorless, colorless, and tasteless gas.
If inhaled, Carbon Monoxide can cause dizziness,
nausea, unconsciousness, and brain damage or
death if contact is allowed to continue.
OPERATING LOCATION
1. Always operate the chipper/shredder outdoors only,
on a firm, level, earthen or grassy area where the unit
will be stable and will stay in position. Never attempt
to operate the unit on a slope, or on wet or slippery
surfaces where you could slip and fall toward the
chipper cone or hopper openings.
2. Never operate the chipper/shredder on asphalt, concrete, or other hard or paved surfaces, as material
being ejected out of the discharge chute could ricochet, causing injury to you or bystanders in the immediate area.
3. Never operate the chipper/shredder where children,
pets, or others who may be unaware of the potential
hazards associated with chipping and shredding
operations could enter the area unexpectedly and be
exposed to these hazards.
4. Never operate the chipper/shredder on rocky or gravel covered surfaces, as this surface debris could
enter the unit and cause extensive damage, or be
ejected out of the machine with sufficient force to
cause a serious injury to you or bystanders.
