L_I_.[ 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.

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 attempting to start

the unit.

The unit is supplied with one 3.04

fluid oz. (90 ml) bottle of SAE 30

SF, SG, SH oil (Fig. 6).

NOTE: Save the bottle of oil. It

can be used to measure

the correct amount

during future oil changes.

See Changing the Oil. Fig. 6

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. 6).

2. Place unit on a flat, level surface.

3. Remove the oil fill plug from the crankcase (Fig.8).

4. Pour the entire bottle of oil into the oil fill hole (Fig. 7).

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

Old fuel is the primary reason for

improper unit performance. Be

sure to use fresh, clean, unleaded

gasoline.

NOTE: Dispose of the old

gasoline in accordance

with federal, state and

local regulations.

NOTE: This is a four cycle

engine. In order to avoid oil Fill Hole

damage to the unit, do

not mix oil with Fig. 7

gasoline.

Definition of Blended Fuels oil FillPlug

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 O-Ring

fuel can make fuel and oil separate

or form acids when stored. Use

fresh fuel (less than 30 days old), Oil Fill

when using alcohol-blended fuel. Hole

Using Blended Fuels

If choosing to use a blended fuel, Fig. 8

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: 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: 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.

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 afuel 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

1. Remove the fuel cap (Fig. 9).

2. Place the gas container's spout into the fill hole on the fuel tank (Fig. 9)

and fill the tank.

_[_ WARNING: Remove fuel cap slowly to avoid injury from fuel

spray. Never operate the unit without the fuel cap securely in place.

_ ARNING: DO NOT USE E85 FUEL IN THIS UNIT. It has

been proven that fuel containing greater than 10% ethanol will

likely damage this engine and void the warranty.

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.
