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 your operator's manual Use the fuel additive STA-BIL® or an equivalent

Always agitate the fuel mix before fueling the unit

Drain the tank and run the engine dry before storing the unit

_WARNING: DO NOT USE E85 FUEL iN THiS UNIT. it |

Using Fuel Additives

The bottle of 2-cycle oil provided with this unit contains 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, such as STA-BIL Fuel Stabilizer or an equivalent. 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) bottle of 2-cycle oil. To

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

bottle into one gallon of unleaded gasoline.

FUELING THE UNiT

WARNING: Gasoline is extremely flammable, ignited

vapors may explode. 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 at a distance

from the area.

WARNING: Remove the fuel cap slowly to avoid injury

from fuel spray. Never operate the unit without the fuel cap securely in place.

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. Remove the fuel cap.

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

NOTE: Do not overfill the tank.

4. Wipe up any fuel that may have spilled.

5. Reinstall the fuel cap.
