ammable and its vapors can explode if ignited. Take
the following precautions:
• Store fuel only in containers specically designed and
approved for the storage of such materials.
• Always stop the engine and allow it to cool before lling
the tank. Never remove the fuel tank cap or add fuel when
the engine is hot. Always loosen the fuel tank cap slowly to
relieve any pressure in the tank
before fueling.
• Always add fuel in a clean, well-ventilated outdoor area
where there are no sparks or ames. DO NOT smoke.
• Never operate the unit without the fuel cap securely
in place.
• Avoid creating a source of ignition for spilled fuel. Wipe up
any spilled fuel from the unit immediately, before starting
the unit. Move the unit at least 30 ft. (9.1 m) from the fueling
source and site before starting the engine. DO NOT smoke.
• Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can kill. Operate this unit only in a
wellventilated outdoor area.

OIL AND FUEL
USING THE RIGHT OIL
Use a high-quality SAE 30 weight oil. DO NOT use dirty oil.
Failure to use clean oil of the correct type can cause premature
engine wear and failure.
ADDING OIL: INITIAL USE
WARNING: OVERFILLING THE
CRANKCASE MAY CAUSE SERIOUS PERSONAL
INJURY. Check the oil level before each use. The
importance of maintaining the proper oil level cannot
be overemphasized. Change the oil according to the
Maintenance Schedule.
NOTE: This unit was shipped without oil in the crankcase. Oil
must be added before starting the unit.
NOTE: This unit comes with a 2.03 uid oz. (60 ml) container
of oil.
1. Set the unit on a flat, level surface.
2. Unscrew the oil ll plug (Fig. 4).
3. Pour the entire container of oil into the oil ll hole (Fig. 4).
DO NOT overll. Refer to Checking the Oil Level.
NOTE: Never add oil to the fuel tank. This unit has a four-cycle
engine. DO NOT mix oil with gasoline.

USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance
problems. Use only fresh, clean unleaded gasoline.
NOTE: This unit has a four-cycle engine. DO NOT mix oil
with gasoline.
Definition of Blended Fuels
Today’s fuels are often a blend of gasoline and oxygenates such
as ethanol, methanol or MTBE (ether). Alcohol-blended fuel
absorbs water. As little as 1% water in the fuel can make fuel
and oil separate, forming acids when stored. ALWAYS use fresh
fuel (less than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
If using a blended fuel:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL
®
or an equivalent
WARNING: DO NOT USE E85 FUEL IN THIS UNIT.
It has been proven that fuel containing greater than
10% ethanol will likely damage this engine and void the
warranty.
Using Fuel Additives
Use a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent, to inhibit corrosion and minimize gum deposits. Add
0.8 oz. (23 ml) of fuel additive per gallon of fuel, according to the
instructions on the container. NEVER add fuel additives directly
to the unit’s fuel tank.
FUELING THE UNIT
WARNING: Gasoline is extremely ammable. Ignited
vapors may explode. Always stop the engine and allow
it to cool before lling the fuel tank. Do not smoke while
lling the tank. Keep sparks and open ames at a
distance from the area.
WARNING: Remove the fuel cap slowly to avoid
injury from fuel spray. Never operate the unit without
the fuel cap securely in place.
WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilled fuel. Do
not start the engine until fuel vapors dissipate.
1. Position the unit with the fuel cap facing up.
2. Slowly remove the fuel cap.
3. Place the fuel container spout into the fuel tank ll hole and ll
the tank.
NOTE: Do not overll the tank.
4. Wipe up any fuel that may have spilled.
5. Reinstall the fuel cap.
6. Move the unit at least 30 ft. (9.1 m) from the fuel container
and the fueling site before starting the engine.
