GASOLINE
The two-cycle engine on this product requires a fuel
mixture of regular unleaded gasoline and a high quality
40:1 2-cycle engine oil (AIR-COOLED) for lubrication of
the bearings and other moving parts. The correct fuel/oil
mixture is 40:1 (see Fuel Mixture Chart). Too little oil or
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 gaso-
line.
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 an engine 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
startingthe engine and letting it run until it stops.Use fresh
fuel next season. See STORAGE instructionsfor addi-
tional 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
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 sta-
bilizer 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-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 tank.
40:1 2-CYCLE AIR-COOLED ENGINE OIL
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
strongly recommended. This oil is specially blended with
fuel stabilizers for increased fuel stability (extends fuel life
up to 5 times longer) and reduced smoke.
If CRAFTSMAN 2-cycle engine oil (AIR-COOLED) is not
available, use a good quality 2-cyoie engine oil (AIR-
COOLED) that has a recommended fuel mix of 40:1.
IMPORTANT! Do not use:
• AUTOMOTIVE OIL
• BOAT OILS (NMMA, BIA, etc.)
These oils do not have proper additives for 2-cyole
engines (AIR-COOLED) 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 quality, 2-cycle engine oil
(AIR-COOLED) into any 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.
• The mixture is now ready for use. Fuel stabilizer can
be added at this time if desired; follow mixing instruc-
tions on the label.

NOTE: Fuel containers may hold more than the specified
amount. If too much gasoline is in the container, the
resulting gas-to-oil fuel mixture will not be correct for
proper engine operation.
