OIL AND FUEL MIXING INSTRUCTIONS

The use of old and/or improperly mixed fuel is the most common cause of performance problems. Use
only fresh, clean unleaded gasoline. Follow the instructions carefully for the proper gasoline/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,
forming acids when stored. ALWAYS use fresh fuel (less than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local regulations.

Using Blended Fuels

If using a blended fuel:
• Always use the fresh fuel mix explained in this operator's manual
• Use a fuel additive
• Always agitate the fuel mix before fueling the unit
CAUTION:
It has been proven that fuel containing greater than 10% ethanol will likely damage this
engine and void the warranty.
Using Fuel Additives
The container of 2-cycle oil provided with this unit includes a fuel additive to help inhibit corrosion
and minimize gum deposits. Always use the brand of 2-cycle oil that came with this unit. If this is
unavailable, use a 2-cycle oil designed for air-cooled engines and mix it with a fuel additive. 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.
Mixing the Fuel
NOTE: This unit comes with a 3.2 oz. (95 ml) container of 2-cycle oil. To obtain the correct fuel mixture
described below, pour the entire container into one gallon of unleaded gasoline.
CAUTION:
to the gasoline and oil mixing instructions on the 2-cycle oil container. Using improperly
mixed fuel can severely damage the engine.
Thoroughly mix the proper ratio of unleaded gasoline with 2-cycle engine oil. Do not mix them
directly in the unit's fuel tank. Use a separate fuel can. Use a 40:1 gasoline/oil ratio. See the table below
for specific gasoline and oil mixing ratios.
