WARNING:
INJURY. Check the oil level before each use. The importance of maintaining the proper oil
level cannot be overemphasized. Change the oil according to the Maintenance Schedule.

USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance problems. Use only fresh, clean
unleaded 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 the fuel additive STA-BIL® or an equivalent
• Drain the tank and run the engine dry before storing the unit
WARNING:
containing greater than 10% ethanol will likely damage this engine and void the warranty.
Using Fuel Additives
Use a fuel additive, such as STA-BIL Fuel Stabilizer or an equivalent, to inhibit corrosion and minimize
