OIL AND FUEL INFORMATION
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
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 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
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 de-signed 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.
NOTE:
Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.
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: 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.
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, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
CAUTION: 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.
