Do not operate the machine while under the influence of drugs, 

alcohol, or any medication that could affect your ability to use it 
properly.

Wear sturdy, rough-soled work shoes and close-fitting slacks and 

shirts. Shirts and pants that cover the arms and legs and steel-
toed shoes are recommended. Never operate this machine in 
bare feet, sandals, slippery or lightweight (e.g. canvas) shoes.

Protect eyes, face, and head from objects that may be thrown 
from the unit. Always wear safety goggles or safety glasses with 
side shields when operating and while performing an adjustment 
or repair.

Always use approved ear protection while you operate the 
product. Noise for a long period can cause noise-induced hearing 
loss.

Always keep hands and feet away from all moving parts and 
under the cutting deck. Contact with moving parts and/or blade 

can amputate fingers, hands, toes and feet.

A missing or damaged discharge cover can cause blade contact or 
thrown object injuries. Do not use a damaged product. Obey the 
maintenance schedule. Only do the maintenance work that you 

find an instruction about in this manual.

ENGINE SAFETY

If a spark arrestor is used, it should 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.

Never start or run the engine inside a closed area. The exhaust 
fumes are dangerous, containing carbon monoxide, an odorless 
and deadly gas.

Operate this unit only in a well-ventilated outdoor area.

Do not tamper with the engine to run it at excessive speeds. The 
maximum engine speed is preset by the manufacturer and is 
within safety limits. See engine manual.

The muffler keeps the noise levels to a minimum and sends the 
exhaust fumes away from the operator. Do not use the product if 

This machine is equipped with 
an internal combustion engine 

and should not be used on or near any unimproved 
forest-covered, brush-covered or grass-covered land 
unless the engine’s exhaust system is equipped with a 
spark arrestor meeting applicable local or state laws 
(if any).

WARNING

the muffler is missing or defective. A defective muffler increases 
the noise level and the risk of fire. Examine the muffler regularly 

to make sure that it is attached correctly and not damaged.

Muffler and engine become hot and can cause burns. Do not 
touch.

Do not modify engine. To avoid serious injury or death, do not 
modify engine in any way. Tampering with the governor setting 
can lead to a runaway engine and cause it to operate at unsafe 

speeds. Never tamper with factory setting of engine governor.

FUEL SAFETY

Fuel is highly flammable, and its vapors can explode if ignited. 
Take precautions when using to reduce the chance of serious 
personal injury.

When refilling or draining the fuel tank, use an approved fuel 
storage container while in a clean, well-ventilated outdoor area. 

Do not smoke, or allow sparks, open flames, or other sources of 

ignition near the area while adding fuel or operating the unit. 

Never fill the fuel tank indoors.

Keep grounded conductive objects, such as tools, away from 
exposed, live electrical parts and connections to avoid sparking or 
arcing. These events could ignite fumes or vapors.

Always stop the engine and allow it to cool before filling the fuel 

tank. Never remove the cap of the fuel tank or add fuel while the 
engine is running or when the engine is hot. Do not operate the 
machine with known leaks in the fuel system.

Loosen the fuel tank cap slowly to relieve any pressure in the 
tank.

Never overfill the fuel tank. Fill the tank to no more than 1/2” 

below the bottom of the filler neck to provide space for expansion 

as the heat of the engine can cause fuel to expand.

Replace all fuel tank and container caps securely and wipe up 
spilled fuel. Never operate the unit without the fuel cap securely 
in place.

Avoid creating a source of ignition for spilled fuel. If fuel is spilled, 
do not attempt to start the engine but move the machine away 
from the area of spillage and avoid creating any source of ignition 
until fuel vapors have dissipated.

Do not start the product if there is fuel or engine oil on the 
product. Remove the unwanted fuel/oil and let the product dry. 

When fuel is spilled on yourself or your clothes, wash your skin 
and change clothes immediately.

Store fuel in containers specifically designed and approved for 
this purpose.
