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
WARNING:
It has been proven that fuel containing greater than 10% ethanol will likely
damage this engine and void the warranty.
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
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
• Use the fuel additive STA-BIL® or an equivalent
• 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:
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.
The bottle of 2-cycle oil contains a fuel additive which will help inhibit
corrosion and minimize the formation of gum deposits. It is
recommended to 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.
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.
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.
FUELING THE UNIT
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.
1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.
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.
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.
