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:

CAUSE SERIOUS PERSONAL INJURY. Check the oil level before each use. The importance of maintaining the proper oil level cannot be overemphasized. Change the oil according to the Maintenance Schedule.

NOTE: This unit was shipped without oil in the crankcase. Oil must

be added before starting the unit.

NOTE: This unit comes with a 2.37 fluid oz. (70 ml) container of oil.

1. Set the unit on a flat, level surface.

2. Unscrew the oil fill plug (Fig. 16).

3. Pour the entire container of oil into the oil fill hole (Fig. 16). DO

NOT overfill. Refer to Checking the Oil Level.

NOTE: Never add

engine. DO NOT mix oil with gasoline.

4. Wipe up any oil that may have spilled.

5. Make sure the O-ring is in place on the oil fill plug (Fig. 16).

6. Reinstall the oil fill plug.

cycle

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 ma

eparate, forming acids when stored. ALWAYS use fresh fuel (less

s 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 the fuel additive STA-BIL

CAUTION:

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, such as STA-BIL Fuel Stabilizer or an equivalent, to inhibit corro 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.
