OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for
improper unit performance. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully for the proper
fuel/oil mixture.
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. It forms acids when stored. When using
alcohol-blended fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable,
follow recommended precautions:
• Always use the fresh fuel mix explained in your opera-
tor'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
The bottle of 2-cycle oil that came with your unit contains a
fuel additive which will help inhibit corrosion and minimize
the formation of gum deposits. It is recommended that you
use our 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.
CAUTION:
bility, pay strict attention to the oil and fuel mix-
ing instructions on the 2-cycle oil container. Using
improperly mixed fuel can severely damage the
engine.
OIL & FUEL INFORMATION
For proper engine opera-
tion and maximum relia-
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.

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.
WARNING:
spray. Never operate the unit without the fuel cap
securely in place.
WARNING:
Wipe up any spilled fuel immediately. Avoid cre-
ating a source of ignition for spilt fuel. Do not
start the engine until fuel vapors dissipate.
