FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TION section of this manual, see mes-
sage labeled IMPORTANT regarding
the use of gasohol in your chain saw.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage. 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.
Craftsman 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.
ENGINE
• Remove spark plug and pour 1 tea-
spoon of 40:1,2-cycle engine oil (air
cooled) through the spark plug open-
ing. Slowly pull the starter rope 8 to
10 times to distribute oil.
• Replace spark plug with new one of
recommended type and heat range.
• Clean air filter.
• Check entire unit for loose screws,
nuts, and bolts. Replace any dam-
aged, 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 sea-
son to another.
• Replace your gasoline can if it starts
to rust.
