FUEL SYSTEM

Under FUELING ENGINE in the OPERA- TION section of this manual, see message labeled IMPORTANT regarding the use of gasohol in your chain saw. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during stor- age. Add stabilizer to the gasoline in the fuel tank or fuel storage container. Follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding stabilizer. Poulan/WEED EATER 40:1, 2-cycle engine oil (air cooled) is blended with fuel stabilizer. If you do not use this oil, you can add a fuel stabilizer to your fuel tank.

HELPFUL TIP

During storage of your gas/ oil mixture, the oil will sepa- rate from the gas.

We recommend that you shake the gas can weekly to insure proper blending of the gas and oil.

ENGINE

SReplace spark plug with new one of rec- ommended type and heat range.

SClean air filter.

SCheck entire unit for loose screws, nuts, and bolts. Replace any damaged, broken,

or worn parts.

SAt the beginning of the next season, use only fresh fuel having the proper gasoline to oil ratio.

OTHER

another.
