• AUTOMOTIVE OIL
- BOAT OILS (NMMA, BIA, etc.)
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.
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.
Gasoline and oil must be premixed in a clean approved
fuel container. Always use fresh regular unleaded gasoline.
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 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 instructions
on the label.
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 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 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.

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.
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.
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.

fuel tank or permanent damage may occur to fuel system
components. Follow these instructions:
• Drain the fuel from He unit into an approved fuel container.
• Drain the fuel lines and carburetor by starting the
engine and letting it run until it stops.
• Allow the engine to cool before storage.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience indicates that alcohol blended fuels,
those that use ethanol or methanol (called gasohol or
oxygenated fuel), can attract moisture and form acidic
gas which will damage your engine. To avoid engine
problems, the fuel system should be emptied before storage of 30 days or longer.
STORE UNIT WITH ALL GUARDS IN
PLACE. POSITION SO THAT ANY SHARP

Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel tank or fuel storage
container. Always follow the mix instructions found on
stabilizer containers. Run engine at least 5 minutes after
adding stabilizer to allow the stabilizer to reach the carburetor.
CRAFTSMAN 40:1 2-cycle engine oil (AIR*COOLED) is
specially blended with fuel stabilizer. If you do not use
this Sears oil, you can add a fuel stabilizer (such as
CRAFTSMAN No. 33500) to your fuel tank.
INTERNAL
ENGINE
• Remove spark plug and pour 1 teaspoon of 40:1 2cycle engine oil (AIR-COOLED) through the spark plug
" opening. Slowly pull the starter rope 8 to 10 times to
distribute oil to inner engine surfaces.
• Replace spark plug with a new one of the recommended
type and heat range. Refer to "Product Specifications."
• Clean air filth. Rear to =Customer Responsibilities."
• Re-install all covers and hardware removed for access;
tighten all screws and fasteners.
• Check entire unit for loose screws, nuts, and bolts.
Replace any damaged, broken, or worn parts.
• Lightly oil external metal surface to prevent rust from
forming.
• Use fresh fuel having the proper gasoline to oil ratio at
the beginning of the next season.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your fuel system wi!t cause problems.
° Store your unit in a weltventilated area and covered, if
possible, to prevent dust and dirt accumulation. Do no
cover with plastic. Plastic cannot breathe and will
induce condensation and eventual rust or corrosion.
