GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life, we recommend
you use Craftsman chain saw bar oif, 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 automatically metered 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.
GASOLINE
The two-cycle engine on this product requires a fuel mixture
of regular unleaded gasoline and a high quality 40:t 2-cycle
engine oil (AIR-COOLED) for lubrication of the bearings and
other moving parts. The correct fue!!oil mixture is40:1 (see
Fuel Mixture Chart)° Too little oil or the incorrectoil type will
cause poor performance and may cause the engine to over-
heat and seize.
Gasoline and oilmust be premixed 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 fuels called gasohot (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 emptied before 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 carburetor cleaner products in the fuel tank or perma-
nent damage may occur1
FUEL STABILIZER
Fuel stabilizer isan acceptable alternative in minimizing the
formation offuel gum deposits during storage. Add stabilizer
to gasoline in fuel tank or storage container. Always follow
the fuel mix ratio found on the stabilizer container Run
engine at least 5 minutes after adding stabilizer to allow the
stabilizer to reach the carburetor, You do not have to drain
the fuel tank for storage if you are using fuel stabilizer.
CRAFTSMAN 40:1 2-cycte 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 tank.
2-CYCLE OIL:
CRAFTSrv_AN 40:1 2-cycte engine oil (AIR_COOLED) is
specialty 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 fue! mix See "Gasoline
and oil mixture" instructions below..
if CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)
is not available, use a good quality 40:1 2-cycle engine oil
(AIR-COOLED) that has a recommended fuet mix ratio
40:1.
IMPORTANTt Do not use:
o AUTOMOTIVE OIL
• BOAT OILS (NMMA, BIA. etc.)
These oils do not have proper additives for 2-cycle (AIR-
COOLED) engines and can cause engine damage.
GASOLINE AND OIL MIXTURE
MIX GASOLINE AND OIL AS FOLLOWS:
° Consult chart for correct quantities.
o Do not mix gasoline and oil directly in the fuel tank.
FOR ONE GALLON:
. Pour 3.2 ounces of high quality, 2-cycle engine oil
(AIR-COOLED) into an empty, approved one gallon
gasoline container°
= Add one gallon of regular unleaded gasoline to the
gallon container, then securely replace the cap.
Shake the container momentarily.
° The mixture isnow ready for use. Fuel stabilizer can
be added at this time if desired; follow mixing instruc-
tions on the label

NOTE; Measure fuel correctly Fuel containers can hold
more than the manufacturer's specified amount, tf too
much gasoline is in the container, the resulting gas-to-oil
ratio will not be correct for proper engine operation
