OIL AND FUEL INFORMATION

WARNING:
OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL
INJURY. Check and maintain the proper oil level in the crank case; it is important and
cannot be overemphasized. Check the oil before each use and change it as needed. See
Changing the Oil.
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 oil. In order to avoid
damage to the unit, put oil in the crankcase before
you attempt to start the unit.
Your unit is supplied with one 2.03 fluid oz. (60 ml.) bottle of
SAE 30 SF, SG, SH oil (Fig. 7).
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. Next,
cut the tip off the funnel spout (Fig. 7).
2. Tip unit so that the back of the engine is facing up in a
vertical position.
3. Remove the oil fill plug from the crankcase (Fig. 8).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 9).
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.
Check oil before each use and change as needed. Refer to
Checking the Oil Level.
RECOMMENDED FUEL TYPE
WARNING:
Add fuel in a clean, well
ventilated outdoor area. Wipe up any
spilled fuel immediately. Avoid creating a
source of ignition for spilt fuel. Do not start
the engine until fuel vapors dissipate.
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.
Old fuel is the primary reason for improper 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 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 a gas stabilizer fuel additive
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of a gas stabilizer 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.
FUELING THE UNIT
WARNING:
Remove fuel cap slowly to avoid injury from fuel spray. Never operate
the unit without the fuel cap securely in place.
1. Remove the fuel cap (Fig. 10).
2. Place the gas container's spout into the fill hole on
the fuel tank (Fig. 10) and fill the tank.
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 the old gasoline in accordance to
Federal, State and Local regulations.

2. Fill the fuel tank with fresh, clean unleaded
gasoline. Refer to Fueling the Unit.
3. Fully press and release the primer bulb 10 times,
slowly. Some amount of fuel should be visible in
the primer bulb and fuel lines (Fig. 11). If you
