Oil And Fuel - Craftsman C410 Operator's Manual

USING THE RIGHT OIL
Use a high-quality SAE 30 weight oil. DO NOT use dirty oil. Failure
to use clean oil of the correct type can cause premature engine
wear and failure.
ADDING OIL: INITIAL USE
WARNING:
DO NOT overfill the crankcase.
OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS
PERSONAL INJURY.
NOTE: This unit was shipped without oil in the crankcase. Oil must
be added before starting the unit.
NOTE: Never add oil to the fuel tank. This unit has a four-cycle
engine. DO NOT mix oil with gasoline.
1. Set the unit on a flat, level surface. Tip the unit back so that
the handlebar touches the ground and the engine is in a
horizontal position (Fig. 5).
2. Unscrew the oil fill plug (Fig. 6).
3. Pour 3.04 fluid oz. (90 ml) of oil into the oil fill hole (Fig. 6).
NOTE: This unit comes with a 3.04 fluid oz. (90 ml) container of oil.
NOTE: DO NOT overfill. Refer to Checking the Oil Level.
4. Wipe up any oil that may have spilled.
5. Make sure the O-ring is in place on the oil fill plug (Fig. 6).
6. Reinstall the oil fill plug.
USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance
problems. Use only fresh, clean unleaded gasoline.
NOTE: This unit has a four-cycle engine. DO NOT mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can make fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
If using a blended fuel:
• Always use fresh unleaded gasoline
• Use a fuel additive
CAUTION:
DO NOT USE E85 FUEL IN THIS UNIT.
It has been proven that fuel containing greater than 10%
ethanol will likely damage this engine and void the warranty.
Using Fuel Additives
Use a fuel additive to inhibit corrosion and minimize gum deposits.
Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel, according to
the instructions on the container. NEVER add fuel additives directly
to the unit's fuel tank.
