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:
15% ethanol will likely damage this engine and void the warranty.
D-Handle
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 60 days
old).
Using Blended Fuels
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
CAUTION:
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.
The bottle of 2-cycle oil that came with the unit contains a fuel additive that
will help inhibit corrosion and minimize the formation of gum deposits.
Always 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.
Thoroughly mix the proper ratio of
2-cycle engine oil with unleaded
gasoline 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 below for specific gas
and oil mixing ratios.
NOTE: One gallon (3.8 liters) of
unleaded gasoline 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:
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:
spray. Never operate the unit without the fuel cap securely in place.
WARNING:
up any spilled fuel immediately. Avoid creating a source of ignition for
spilt fuel. Do not start the engine until fuel vapors dissipate.
1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.
2. Place the gas container's spout into the fill hole on the fuel tank and fill
the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site
before starting the engine.
