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 3.04 fluid oz. (90 ml.) bottle of SAE

30 SF, SG, SH oil (Fig. 4).

NOTE: Save the bottle of oil. 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. 4).

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. 6).

4. Pour the entire bottle of oil into the oil fill hole (Fig. 5).

NOTE: Never add oil to the fuel or fuel tank.

OIL AND FUEL INFORMATION

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

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 make fuel and

oil separate 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.

FUELING THE UNIT

1. Remove the fuel cap (Fig. 7).

2. Place the gas container’s spout into the fill hole on the fuel

tank (Fig. 7) 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.

WARNING:

Remove fuel cap slowly to avoid

injury from fuel spray. Never operate the unit

without the fuel cap securely in place.

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.

WARNING:

Operate this unit only in a well-ventilated outdoor area. Carbon monoxide

exhaust fumes can be lethal in a confined area.

WARNING:

Avoid accidental starting. Make sure you are in the starting position when

pulling the starter rope (Fig. 10). To avoid serious injury, the operator and unit must be

in a stable position while starting.

Make sure that any Add-On item is installed correctly and secure before starting the unit.
