GASOLINE
The two-cycle engine on this product requires a fuel mix-
ture 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 mix-
ture 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
formation of acids during storage. Acidic gas can dam-
age the fuel system of an engine while in storage. To
avoid engine problems, the fuel system should be emp-
tied before storage for 30 days or longer. Drain the gas
tank, then run the fuel out of the carburetor and fue! 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.

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) an'dreduced 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 fuel mix ratio of
40:1.
IMPORTANT! Do no use:
• AUTOMOTIVE OIL
- BOAT OILS (NMMA, BIA, etc.)
These oils do not have proper additives for 2-cycle
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, 40:1 2-cycle engine oil
(AIR-COOLED) into an empty, approved one gallon
gasoline container.
° Add one gallon of regular unleaded gasoline to the gal-
lon 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 instructions
on the label.

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