OIL AND FUEL MIXH_G H_STRUCTIONS

Old and/or improperly mixed fuel are the main reasons
for the unit not running properly. Be sure to use fresh
(less than 60 days old), clean unleaded fuel. Follow the
instructions carefully for the proper fuel/oil mixture.

Definition of Bmended Fuels
Today's fueis are often a bbnd of gasoiine 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 and
Headsto formation of acids during storage. When using

aicohoi-bbnded fuel use fresh fuel

Using Bmended Fuems

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 shake the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing
the unit

To Obtain Correct Fuem Mix:
Thoroughly mix the proper ratio of 2-cycb engine oil

with unleaded gasoline in a separate fuel can. Use a 40:1
fueVoil ratio. Do not mix them directly in the engine fuel
tank. See the Fuel Mixture Table 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-cycb oil makes a 40:1 fueVoil ratio.

Using FuemAdditives

The bottle of 2-cycb 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 always use Craftsman 2-cycb oil

with this unit.
If Craftsman 2-cycb oil is unavailable, use a good 2-

cycle oil designed for air-coobd 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.
