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.
