Fig. 3 OIL AND FUEL INFORMATION RECOMMENDED OIL TYPE WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check and maintain the proper oil level in the crankcase; it is important and cannot be overemphasized. Check the oil before each use and change it as needed. See Changing the Oil. Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each use and change the oil regularly. Failure to use the correct oil, or using dirty oil, can cause premature engine wear and failure. Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, SH. ADDING OIL TO CRANKCASE: INITIAL USE NOTE: This unit is shipped without oil in the engine. To avoid damage to the unit, put oil in the crankcase prior to starting the unit. This unit is supplied with one 2.03 fl.oz. (60 ml) bottle of SAE 30 SF, SG, SH oil (Fig. 4). NOTE: Save the empty oil bottle. It can be used to measure the Fig. 4 correct amount during future oil changes. See Changing the Oil. 1. Unscrew the top of the bottle of oil and remove the paper seal covering the opening. Replace the top and cut the tip off the funnel spout (Fig. 4). Oil Plug 2. With the unit on a flat level surface, remove the oil plug (Fig. 5). 3. Pour the entire bottle of oil into the oil fill hole (Fig. 6). NOTE: Never add oil to the fuel or fuel tank. 4. Wipe up any oil that may have spilled and reinstall the oil fill Fig. 5 plug. Check oil before each use and change as needed. Refer to Checking the Oil Level. RECOMMENDED FUEL TYPE Old fuel is the primary reason for poor unit performance. Be sure to use fresh, clean, unleaded gasoline. NOTE: This is a four cycle engine. In order to avoid damage to the unit, do not mix oil with gasoline. Definition of Blended Fuels Oil Fill Hole Today's fuels are often a blend of gasoline and oxygenates such as Fig. 6 ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel. OIL AND FUEL INFORMATION Using Blended Fuels WARNING: 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. If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions: • Always use fresh unleaded gasoline • Use the fuel additive STA-BIL® or an equivalent • Drain tank and run the engine dry before storing unit Using Fuel Additives WARNING: Gasoline is extremely flammable. Ignited vapors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area. The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel according to the instructions on the fuel additive container. NEVER add fuel additives directly to the unit's gas tank. FUELING THE UNIT WARNING: Add fuel in a clean, level and well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate. 1. Remove the fuel cap (Fig. 7). WARNING: Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place. 2. Place the gas container's spout into the fill hole on the fuel tank and fill. NOTE: Do not overfill the tank. 3. Wipe up any gasoline that may have spilled. 4. Reinstall the fuel cap. 5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine. NOTE: Dispose of any old gasoline in accordance with federal, state and local regulations. Fuel Tank Fig. 7 STARTING/STOPPING INSTRUCTIONS WARNING: Operate this unit only in a well-ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area.
