STARTING INSTRUCTIONS

1. Mix gas with oil. See Stop/Off (O)-_ Off and Fuel Mixing /_- y/___ /

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperlymixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/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. It forms acids when stored. When using alcohol-blended

fuel, use fresh fuel (less than 60 days old).

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use the fresh fuel mix explained in your operator's manual

• Always agitate the fuel mix before fueling the unit

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

Using Fuel Additives

The bottle of 2-cycle oilthat came with your unitcontains a fuel additive which will help inhibit corrosion and minimizethe formation of gum deposits. It isrecommended that you use our 2-cycle oil withthis unit. If unavailable, useagood 2-cycle oil de-signed forair-cooled engines along with afuel additive, such as STA-BIL®Gas Stabilizer or an equivalent.Add

0.8 oz. (23ml.) of fuel additive per gallon of fuel according to theinsfructions on the container. NEVERadd fuel additives directly to the unit's fueltank.

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline ina separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly inthe engine fuel
