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
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).
2. With the unit on a fl at level surface, remove the oil plug (Fig. 5).
3. Pour the entire bottle of oil into the oil fi ll 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 fi ll
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.
Defi nition 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 form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.

Using Blended Fuels
WARNING:
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:
the engine and allow it to cool before fi lling the fuel tank. Do not smoke while fi lling the
tank. Keep sparks and open fl ames 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
Primer Bulb
deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel
Air Filter
according to the instructions on the fuel additive container. NEVER add fuel additives directly to the
Cover

FUELING THE UNIT
WARNING:
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:
without the fuel cap securely in place.
