GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life,we recommend you
use Craftsman chain saw bar oil. If Craftsman bar oil is not
available, you may_se a good grade SAE30 oil until you are
able to obtain Craftsman brand. The oil output is automati-
caUy metered during operation. Your saw will use approxi-
mately onetank'0f 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 thisproduct requiresa fuel mixture
of regular unleaded gasoline and a quality 40:1
2_cycle engine oil (AIR-COOLED) for lubricationof the bear-
ings and other moving parts.The correct fuel/oil mixture is
40:1 (see Fuel Mixture Chart).Too littleoilor the incorrect oil
type will cause poor performance and may cause the engine
to overheat and seize.
Gasoline and oil must 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 gasohol (or using ethanol or methanol) can
attract moisture,which leads to oil/gas separation and for-
mation of acids during storage. Acidic gas can damage the
fuel system of amengine while in storage. 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
permanent damage may occur.
FUEL STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing the
formation of fuel gum deposits during storage. Add stabiliz-
er to gasoline in fuel tank Orstorage container. Always fol-
low the fuel mix ratio found on the stabilizer container. Run
engine at least 5 minutes after adding stabilizer to allowthe
stabilizer to reach the carburetor.You do not have to drain
the fuel tank forstorage if you are using fuel stabilizer.
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 to your fuel tank.
40:1 2-CYCLE AiR-COOLED ENGINE OIL
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
strongly recommended.This oil is specifically blended with
fuel stabilizers for increased fuel stability (extends fue! life
up to 5 times longer) and reduced smoke.
If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
not available, use a good quality 2-cycle engine oil (AIR-
COOLED) that has a recommended fuet mix ratio of 40:1. •
IMPORTANT! Do not use:
• 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.
• Do not mix gasoline and oil directly in the unit's fuel tank.
FOR ONE GALLON:
• Pour 3.2 ounces of high quatity, 40:t 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 momentar)ly:
The mixture is now ready for _e. Fuel stabilizer can be
added at this time if desired; follow mixing instructions on
the label.
FUEL MIXTURE CHART
40:1 Fuel:Oil Mix Ratio
Gasoline Oil {fl.oz.)
1 gallon 3.2
2.5 gallons 8.0
NOTE: Fuel containers may hold more than the specified
amount. If too much gasoline is in the container, the result-
ing gas-to-oil fuel mixture will not be correct for proper
engine operation.
