OIL AND FUEL INFORMATION
Old or improperly mixed fuel are usually
the main reasons for the unit not running
properly. Be sure to use fresh, clean fuel and
follow the instructions carefully for the proper
fuel/oil mixture.
NOTE: Alcohol-blended fuel absorbs moisture
(water). As little as 1% moisture in the
fuel can cause fuel and oil to separate
and form acids when stored. If this
type of fuel must be used, use fresh
fuel (less than 60 days old), and mix
according to the mixing instructions.
DEFINITION OF BLENDED FUELS
Today's fuels are often a blend of gasoline
and one or more oxygenates such as ethanol,
methanol or MTBE (ether).
USE OF BLENDED FUELS
If you choose to use a blended fuel or its use
is unavoidable, the following precautions are
recommended.
1. Always use fresh fuel mix per your
operator's manual.
2. Use the special additive STA-BIL® or
an equivalent.
3. Always agitate the fuel mix before fueling
the unit.
4. Drain the tank and run the engine dry
before storing the unit.
USE OF FUEL ADDITIVES
The use of fuel additive, such as STA-BIL®
Gas Stabilizer or an equivalent, will inhibit
corrosion and minimize the formation of gum
deposits. Add 0.8 oz (23 ml) per gallon of fuel
per instructions on container. NEVER add fuel
additives directly to the unit's fuel tank. Using
a fuel additive can keep fuel fresh for up to six
(6) months.
CAUTION: For proper engine
operation and maximum reliability,
pay strict attention to the oil and
fuel mixing instructions on the
2-cycle oil container. Use a 32:1
fuel/oil ratio. Use 2-cycle oil. Using
improperly mixed fuel can severely
damage the engine.
WARNING: Pressure can build up
in the fuel tank. Loosen the fuel
tank cap slowly to relieve any
pressure in the tank.

WARNING: Gasoline is extremely
flammable and its vapors can
explode if they are ignited. To avoid
serious personal injury, 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 away from
the area.
OIL AND FUEL MIXING INSTRUCTIONS
Thoroughly mix the proper ratio of 2-cycle
engine oil with unleaded gasoline in a
separate fuel can, 32:1. Do not mix them
directly in the engine fuel tank. See the table
below for specific gas and oil mixing ratios.
