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 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.

CAI ITlll3&l' For proper engine

nunnvn 1I, 0peration 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.
