7. Oil / Fuel

Old fuel is usually the main reason for the unit not running properly. Be sure to use fresh, clean, unleaded fuel.

NOTE

Alcohol-blended fuel absorbs moisture (water). As little as 1% moisture in the fuel can cause it to separate and form acids when stored. If this type of fuel must be used, use fresh fuel (less than 60 days old).

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 unleaded fuel 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 0.8oz (23ml) 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.
