OIL AND FUEL

USING THE RIGHT OIL

Use a high-quality SAE 30 weight oil. DO NOT use dirty oil. Failure to use clean oil of the correct type can cause premature engine wear and failure.

ADDING OIL: INITIAL USE

WARNING: DO NOT overfill the crankcase.

OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS

PERSONAL INJURY.

NOTE: This unit was shipped without oil in the crankcase. Oil must be added before starting the unit.

NOTE: Never add oil to the fuel tank. This unit has a four-cycle engine. DO NOT mix oil with gasoline.

1.

Set the unit on a flat, level surface. Tip the unit back so that the handlebar touches the ground and the engine is in a horizontal position (Fig. 5).

2. Unscrew the oil fill plug (Fig. 6).

3. Pour 3.04 fluid oz. (90 ml) of oil into the oil fill hole (Fig. 6).

NOTE: This unit comes with a 3.04 fluid oz. (90 ml) container of oil.

USING THE RIGHT FUEL

The use of old fuel is the most common cause of performance problems. Use only fresh, clean unleaded gasoline.

NOTE: This unit has a four-cycle engine. DO NOT mix oil with gasoline.

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 fresh unleaded gasoline

• Use a fuel additive

CAUTION: DO NOT USE E85 FUEL IN THIS UNIT.

It has been proven that fuel containing greater than 10% ethanol will likely damage this engine and void the warranty.

Using Fuel Additives

Use a fuel additive to inhibit corrosion and minimize gum deposits.

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.

WARNING: Add fuel in a clean, well-ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

1. Position the unit with the fuel cap facing up.

2. Slowly remove the fuel cap.

3. Place the fuel container spout into the fuel tank fill hole and fill the tank.
