GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life, we recommend
you use CPaftsman chain saw bar oil. If Craftsman bar oil
is not available, you may use a good grade SAE30 oil
until you are able to obtain Craftsman brand.The oil out-
put is automaticallymetered during operation.Your saw
will use approximately one tank of bar oil for every tank
of fuel mix. Always fill the bar oil tank when you fill
the fuel tank.
GASOUNE
The two-cycle engine on this productrequiresa fuel mixture
of regularunleadedgasoline and a highquality 40:1 2-cycle
engineoil (AIR-COOLED) for lubricationofthe beadngs and
other moving parts. The correct fuel/oil mixture is40:1 (see
Fuel MixtureChart). Too little oil orthe incorrectoil type will
cause poorperformanceand may cause the engine to over-
heat and seize.
Gasoline and oil must be pmmixed in a clean approved fuel
container. Always use fresh regular unleaded gasoline.
This engine is certified to operate on unleaded gasoline.
IMPORTANT: Experience indicates that alcohol
blended fuelscalled gasohol (or using ethanol or metha-
nol) can attract moisture, which leads to oil/gas separa-
tion and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in stor-
age. To avoid engine problems, the fuel system should
be emptiedbefore storage for 30 days or longer. Drain
the gas tank, then run the fuel out of the carburetor and.
fuel lines by starting the engine and letting it run until it
stops. Use fresh fuel next season. See STORAGE
instructions for additional information. Never use engine
or carburetorcleaner products in the fuel tank or perma-
nent damage may occur.
FUEL STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing the
formationoffuelgum depositsduringstorage. Addstabilizer
to gasoline in fuel tank or storagecontainer. Always follow
the fuel mix ratio found on the stabilizer container. Run
engine at least5 minutesafter addingstabilizer to allow the
stabilizerto reach the carburetor.You do not have to drain
the fuel tank for storage if you are using fuel stabilizer.
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) Is
speciallyblended with fuel stabilizers.If you do not use this
Sears oil, you san add a fuel stabilizer (such as Craftsman
No. 33500) to your fuel tank.
2-CYCLE OIL:
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
specially blended with fuel stabilizers.If you do not use
this Sears oil, you can add a fuel stabilizer (such as
Craftsman No. 33500) to your fuel mix. See Gasoline
and oil mixture"instructionsbelow.
If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)
is not available, use a good quality40:1 2-cycle engine oil
(AIR-COOLED) that has a recommendedfuel mix ratio
40:1.
IMPORTANTI Do not usa:
• AUTOMOTIVE OIL

COOPED) engines and can cause engine damage.

(AIR-COOLED) into an empty, approved one gallon
gasoline container.
• Add one gallon of regular unleededgasoline t o the
galloncontainer, then securely replacethe cap.

FUEL MIXTURE CHART
40:1 Fuel:Oil Mix Ratio
1 gallon 3.2
2.5 gallons 8.0
NOTE: Measure fuel correctly. Fuel containers can hold
more than the manufacturer's specified amount. If too
much gasoline is in the container, the resulting gas-to-oil
ratio will not be correct for proper engine operation.
