OiL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit not
running properly. Be sure to use fresh, clean unleaded fuel. Follow the
instructions
carefully for the proper fuel/oil mixture.
Definition
of Blended
Fuels
WARNING
: It has been proven that fuel containing greater than I
10% ethanol will likely damage this engine and void the warranty. I
I
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. It forms acids when
stored. When using alcohol-blended
fuel, use fresh fuel (less than 30 days
old).
Using Blended
Fuels
WARNING:
For proper engine operation and maximum
reliability, pay strict attention to the oil and fuel mixing
instructions
on the 2-cycle oil container. Using improperly mixed
fuel can severely damage the engine.
If choosing to use a blended fuel, or its use is unavoidable,
follow
recommended
precautions:
Always use the fresh fuel mix explained in the operator's
manual
Always agitate the fuel mix before fueling the unit
Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
It is recommended
to use the manufacturers
2-cycle oil with this unit. If
unavailable, use a good 2-cycle oil designed for air-cooled engines along
with a fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent. 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.
Mixing The Fuel
Thoroughly mix the proper ratio of
2-cycle engine oil with unleaded fuel
in a separate fuel can. Use a 40:1 fuel/
oil ratio. Do not mix them directly in
the engine fuel tank. See the table for
specific gas and oil mixing ratios.

the unit came with a bottle of 2-cycle oil; pour the entire bottle into
1 gallon of gas and mix thoroughly.
NOTE:
One gallon (3.8 liters) of unleaded fuel mixed with one 3.2 oz. (95
ml) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.
NOTE:
Dispose of the old fuel/oil mix in accordance
to Federal, State and
Local regulations.

WARNING:
Gasoline is extremely flammable. Ignited vapors
may explode. Always stop the engine and allow it to cool before
filling the fuel tank. Do not smoke while filling the tank. Keep
sparks and open flames at a distance from the area.
FUELING THE UNIT
WARNING:
Remove 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, level and 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.
Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.
