RECOMMENDED OIL TYPE
WARNING:
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 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
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
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 filling the fuel tank. Do not smoke while filling the
Primer Bulb
Air Filter tank. Keep sparks and open flames at a distance from the area.
Cover
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:
spilled fuel immediately. Avoid creating a source of ignition for spilled fuel. Do not start the
Fuel Cap
engine until fuel vapors dissipate.
1. Remove the fuel cap (Fig. 7).
WARNING:
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.
