Keep sparks and open flames away from the area. 4. Drain the tank and run the engine dry before storing the unit. USE OF FUEL ADDITIVES RECOMMENDED OIL TYPE The use of fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposit. Add 0.8 oz (23 ml) per gallon of fuel per instructions on container. NEVER add fuel additives directly to the unit's fuel tank. Using a fuel additive can keep fuel fresh for up to six (6) months. A 4 oz. (0.118 liter) bottle of 2-cycle engine oil is included with your product. OIL AND FUEL MIXING INSTRUCTIONS RYOBI 2-cycle oil is recommended for this outdoor power tool. If another brand of 2-cycle oil is used, make sure it is high quality oil, formulated for 2-cycle, air-cooled engines. DANGER: Combustible mixture contains petroleum distillate. Store away from heat or open flame. Harmful or fatal if swallowed. If swallowed, do not induce vomiting. CALL PHYSICIAN IMMEDIATELY. Avoid prolonged contact with skin. Wash thoroughly after handling. Do not reuse bottle. NOTE: For proper engine operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Use a 32:1 fuel/oil ratio when you use 2-cycle oil. Using improperly mixed fuel can severely damage the engine. Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can, 32:1. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios. RECOMMENDED FUEL TYPE Use clean, fresh, unleaded gasoline that is less than 60 days old. NOTE: Alcohol blended fuel absorbs moisture (water). As little as 1% moisture in the fuel can cause fuel and oil to separate and form acids when stored. If this type of fuel must be used, use fresh fuel, (less than 60 days old) and mix according to the mixing instructions. DEFINITION OF BLENDED FUELS Today's fuels are often a blend of gasoline and one or more oxygenates such as ethanol, methanol or MTBE (ether).
