The purpose of safety symbols is to attract your attention to

possible dangers. The safety symbols, and their explanations, deserve your careful attention and understanding. The safety warnings do not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention measures.

SYMBOL MEANING

DANGER: Signals an EXTREME hazard.

Failure to obey a safety DANGER signal WILL result in serious injury or death to yourself or to others.

WARNING: Signals a SERIOUS hazard.

Failure to obey a safety WARNING signal CAN result in serious injury to yourself or to others.

CAUTION: Signals a MODERATE hazard.

Failure to obey a safety CAUTION signal MAY result in property damage or injury to yourself or to others.

NOTE: Advises you of information or instructions vital to the

SPARK ARRESTOR NOTE

NOTE: For users on U.S. Forest Land and in the states of

California, Maine, Oregon and Washington. All U.S. Forest Land and the state of California (Public Resources Codes 4442 and

4443), Oregon and Washington require, by law that certain internal combustion engines operated on forest brush and/or grass-covered areas be equipped with a spark arrestor, maintained in effective working order, or the engine be constructed, equipped and maintained for the prevention of fire. Check with your state or local authorities for regulations pertaining to these requirements. Failure to follow these requirements could subject you to liability or a fine. This unit is factory equipped with a spark arrestor. Replacement requires Muffler Assembly Part #753-05245, installed at a Sears

WARNING: Gasoline is highly flammable and its vapors

• Store fuel only in containers specifically designed and approved for the storage of such materials.

Always stop the engine and allow it to cool before filling the tank. Never remove the fuel tank cap or add fuel when the engine is hot. Always loosen the fuel tank cap slowly to relieve any pressure in the tank before fueling.

Always add fuel in a clean, well-ventilated outdoor area where there are no sparks or flames. DO NOT smoke.

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

Avoid creating a source of ignition for spilled fuel. Wipe up any spilled fuel from the unit immediately, before starting the unit.

Move the unit at least 30 ft. (9.1 m) from the fueling source and

site before starting the engine. DO NOT smoke.

Never start or run the unit inside a closed room or building. Breathing exhaust fumes can kill. Operate this unit only in a well

ventilated outdoor area.

WHILE OPERATING

Wear heavy long pants, boots, gloves and a long sleeve shirt. Do not wear loose clothing, jewelry, short pants, sandals or go

barefoot. Secure hair above shoulder level.

The trimmer attachment shield must always be in place while

operating the unit. Do not operate unit without both trimming lines extended, and the proper line installed. Do not extend the trimming line beyond the length of the shield.

This unit has a clutch. The cutting head remains stationary when

the engine is idling. If it does not, take the unit to a Sears or other qualified service dealer for an adjustment.

Adjust the handle to provide the best grip.

Be sure the trimmer attachment is not in contact with anything before starting the unit.

Use the unit only in daylight or good artificial light.

firm grip on both handles or grips. Keep hands, face, and feet away from all moving parts. Do not

touch or try to stop the trimmer attachment when it rotates. Do not touch the engine, gear housing or muffler. These parts get

extremely hot from operation, even after the unit is turned off. Do not operate the engine faster than the speed needed to cut, trim

or edge. Do not run the engine at high speed when not cutting.

Always stop the engine when cutting is delayed or when walking

from one cutting location to another. If you strike or become entangled with a foreign object, stop the

engine immediately and check for damage. Do not operate before repairing damage. Do not operate the unit with loose or

damaged parts.

Turn the engine to off and disconnect the spark plug for

maintenance or repair.

USING THE RIGHT OiL

Use a high-quality SAE 30 weight oil of API (American Petroleum institute) service class SJ. DO NOT use dirty oil. Failure to use clean oil of the correct type can cause premature engine wear and failure.

ADDING OiL: iNiTiAL USE

WARNING: OVERFILLING THE CRANKCASE MAY

CAUSE SERIOUS PERSONAL iNJURY. Check the oil level before each use. The importance of maintaining the proper

oil level cannot be overemphasized. Change the oil according to the Maintenance Schedule.

NOTE: This unit was shipped without oil in the crankcase. Oil must

be added before starting the unit.

NOTE: This unit comes with a 3.04 fluid oz. (90 ml) bottle of oil.

1. Unscrew the top of the oil bottle. Remove the paper seal. Reinstall the top of the oil bottle.

2. Remove the cap from the oil bottle. Cut the tip off the funnel

spout (Fig. 7).

3. Set the unit on a fiat, level surface.

4. Unscrew the oil fill plug (Fig. 8).

5. Pour the entire bottle into the oil fill hole (Fig. 8). DO NOT

overfill. Refer to Checking the Oil Level.

NOTE: Never add oil directly to the fuel tank. This unit has a four-

cycle engine. DO NOT mix oil with gasoline.

6. Wipe up any oil that may have spilled.

7. Reinstall the oil fill plug.

NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 8). NOTE: Save the empty oil bottle. Use the bottle to measure the

correct amount of oil during future oil changes.

USING THE RIGHT FUEL

The use of old fuel is the most common cause of performance problems. Use only fresh, clean unleaded 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, forming acids when stored. ALWAYS use fresh fuel (less than 30 days old).

NOTE: Dispose of old fuel according to federal, state and local

regulations.

Using Blended Fuels if using a blended fuel:

• Always use fresh unleaded gasoline Use the fuel additive STA-BIL® or an equivalent Drain the tank and run the engine dry before storing the unit

has been proven that fuel containing greater than 10% ethanol will likely damage this engine and void the warranty.

Using Fuel Additives

Use a fuel additive, such as STA-BIL Fuel Stabilizer or an equivalent, to inhibit corrosion and minimize gum deposits. 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 fuel tank.

FUELING THE UNiT

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: Remove the 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 spilled fuel. Do not start the engine until fuel vapors dissipate.

1. Position the unit with the fuel cap facing up.

2. Remove the fuel cap.

3. Place the fuel container spout into the fill hole on the fuel tank and fill the tank.

NOTE: Do not overfill the tank.

4. Wipe up any fuel that may have spilled.

5. Reinstall the fuel cap.

6. Move the unit at least 30 ft. (9.1 m) from the fuel container and
