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 30 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 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 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.
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.

it has been proven that fuel containing greater than 10% ethanol will likely damage this engine and void the warranty.
Mixing the Fuel
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.
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 according to federal, state and
local regulations.
