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.

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

Remove spark plug and pour 1 teaspoon

of 40:1, 2-cycle engine oil (air cooled)

through the spark plug opening. Slowly

pull the starter rope 8 to 10 times to distrib-

ute oil.

Replace spark plug with new one of rec-

ommended type and heat range.

Clean air filter.

Check entire unit for loose screws, nuts,

and bolts. Replace any damaged, broken,

or worn parts.

At the beginning of the next season, use

only fresh fuel having the proper gasoline

to oil ratio.

OTHER

Do not store gasoline from one season to

another.

Replace your gasoline can if it starts to

rust.
