•Add fuel in a clean, well-ventilated area outdoors where there are no sparks or flames. Slowly remove the fuel cap only after stopping engine. Do not smoke while fueling or mixing fuel. Wipe up any spilled fuel from the unit immediately.
•Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.
•Move the unit at least 30 feet (9.1 m) from the fueling source and site before starting the engine. Do not smoke. Keep sparks and open flames away from the area while adding fuel or operating the unit.

SECTION 4: OIL AND FUEL INFORMATION
DANGER: OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY! The importance of checking and maintaining the proper oil level in the crank case cannot be overemphasized. Check oil before each use and change as needed. See Changing the Oil in the Maintenance and Repair Instructions section.
RECOMMENDED OIL TYPE
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 being filled with oil. In order to avoid damage to the unit, put oil in the crankcase before attempting to start unit.
Your unit is supplied with one 3.4 fluid oz. (100 ml.) bottle of SAE 30 SF, SG, SH oil (Fig. 4).
NOTE: Save the bottle to measure the correct amount for future oil changes. See Changing the Oil in the Maintenance and Repair Instructions section.
1.Unscrew the top of the bottle of oil and remove the paper seal covering the opening. Replace top. Cut the tip off the funnel spout (Fig. 4).
2.Place the unit on a flat level surface.
3.Remove the oil plug / dipstick from the crankcase (Fig. 5).

Oil Fill 
Fig. 6
NOTE: Never add oil to the fuel or fuel tank.
5.Wipe up any oil that may have spilled and reinstall the oil fill plug/dipstick.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for the unit not running properly. 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
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 ruin the fuel or form acids when stored. Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If you choose 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
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 container. NEVER add fuel additives directly to the unit's gas tank.
