OIL AND FUEL

OIL AND FUEL MIXING INSTRUCTIONS

The use of old and/or improperly mixed fuel is the most common cause of performance problems. Use only fresh, clean unleaded gasoline. Follow the instructions carefully for the proper gasoline/oil mixture.

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 the fresh fuel mix explained in this operator's manual
- Use a fuel additive
• Always agitate the fuel mix before fueling the unit

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

The container of 2-cycle oil provided with this unit includes a fuel additive to help inhibit corrosion and minimize gum deposits. Always use the brand of 2-cycle oil that came with this unit. If this is unavailable, use a 2-cycle oil designed for air-cooled engines and mix it with a fuel additive. 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.

Mixing the Fuel

NOTE: This unit comes with a 3.2 oz. (95 ml) container of 2-cycle oil. To obtain the correct fuel mixture described below, pour the entire container into one gallon of unleaded gasoline.

CAUTION: For proper engine operation and maximum reliability, pay strict attention to the gasoline and oil mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

Thoroughly mix the proper ratio of unleaded gasoline with 2-cycle engine oil. Do not mix them directly in the unit's fuel tank. Use a separate fuel can. Use a 40:1 gasoline/oil ratio. See the table below for specific gasoline and oil mixing ratios.

Unleaded gasoline 2-cycle oil
1 gallon U.S.(3.8 liters)	3.2 fl. oz.(95 ml)
1 liter 25 ml

• Cut at a slow, even pace.

WARNING: Blade thrust can occur when the spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction and possibly lose control of the unit. Blade thrust can occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut.

- Frequently check the condition of the blade. As it wears, the blade will become smaller, reducing the cutting depth. Replace the blade as needed. Refer to Replacing the Blade.

WARNING: The blade will continue to spin for a while after the unit is turned off. To avoid serious personal injury, do not touch a coasting blade.

WARNING: To avoid serious personal injury, always turn the unit off before removing debris from the unit. Allow the blade to come to a complete stop.

MAINTAINING THE AIR FILTER

Failure to maintain the air filter can result in poor performance or can cause permanent damage to the engine. Engine failure due to improper air filter maintenance is not covered by the product warranty.

Cleaning the Air Filter

1. Open the air filter cover: Hook your fingers behind the cover tab. To unlock the air filter cover, pull it to the left and away from the engine. This may require a firm pull. Swing the air filter cover to the right (Fig. 17).
2. Remove the air filter from inside the air filter cover (Fig. 17).
3. Wash the air filter in detergent and water. Rinse the air filter thoroughly and allow it to dry.
4. Lightly coat the air filter with clean SAE 30 oil.
5. Squeeze the air filter to spread and remove excess oil.
6. Reinstall the air filter inside the air filter cover (Fig. 17).

NOTE: Operating the unit without the air filter and air filter cover will VOID the warranty.

1. Close the air filter cover: swing the air filter cover to the left and press it closed until the lock tab snaps into place (Fig. 17).
