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. Failureto follow these requirements could subject you to liability or a fine. This unit is factory equipped with a spark arrestor. If it requires

replacement, ask your LOCAL SERVICE DEALER to install the Accessory Part #753=05245 Muffler Assembly.

All information, illustrations, and specifications in this manual are based on the latest product information available at the time of printing. We reserve the right

to make changes at any time without notice.

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.

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

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.

L_I_.[ WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE

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

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

TiPS FOR BEST EDGING RESULTS

• After starting the engine, keep the unit tilted back so the blade

does not touch the ground. Move the unit to the desired

location and slowly lower the blade into the ground.

Do not force the edger. Edge the first time at a lesser depth

(no more than 1/2" depth cut per pass), then do the area again with a deeper setting.

• Walk the edger at a slow, even pace.

Check the blade condition (Fig. 15). As it wears it becomes smaller, thus reducing the cutting depth performance. Replace the blade when it no

longer makes contact with the ground.

CHECKING THE OiL LEVEL The importance of checking and maintaining the proper oil level in the

crankcase cannot be overemphasized. Check oil before each use:

1. Stop the engine and allow oil to drain into the crankcase.

2. Place unit on a flat, level surface.

3. Keep dirt, grass clippings and other debris out of the

engine. Clean the area around the dipstick before

removing it.

4. Remove the oil fill plug.

5. Look into the oil fill hole, use a flashlight if needed. The oil should be just touching the

inner most thread (Fig. 18).

6. Ifthe oil level is not touching the inner most thread on the

oil fill hole, add a small amount of oil to the oil fill hole

and recheck (Fig. 21). Repeat this procedure until the oil

level reaches the inner most O-Ring

thread on the oil fill hole.

NOTE: Do not overfill the unit. NOTE: Make sure the O-ring is Hole

CHANGING THE OiL

Change the oil while the engine is still warm. The oil will flow freely and carry

away more impurities.

AiR FILTER MAINTENANCE

Cleaning the Air Filter

Failure to maintain the air filter properly can result in poor

performance or can cause permanent damage to the engine.

1. Open the air filter cover. Unscrew the knob on the left

side of the cover. Swing the cover out (Fig. 23).

Remove the air filter (Fig. 23).

Wash the filter in detergent and water. Rinse the filter thoroughly and

Hooks

allow it to dry.

4. Apply enough clean SAE 30 motor oil to lightly coat the filter.

5. Squeeze the filter to spread and remove excess oil.

6. Replace the filter (Fig. 23).

NOTE: Operating the unit without the air filter, will VOID the warranty.

7. Make sure the back plate is correctly positioned (Fig. 23).

8. Swing the air filter cover closed and tighten the knob (Fig. 23).

iDLE SPEED ADJUSTMENT The idle speed of the engine is adjustable. An idle adjustment screw is

between the air filter cover and the engine starter housing (Fig. 24). NOTE: Careless adjustments can seriously damage the unit. Aside from idle

speed, only a Sears or other qualified service dealer should make carburetor adjustments.

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

I _i_ ! WARNING: The blade may spin during idle speed adjustments.

Wear protective clothing and observe all safety instructions toprevent serious personal injury.

1. Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting/Stopping Instructions.

2. Release the throttle lever and let the engine idle. If the Idle Adjustment engine stops, insert a small Screw

Phillips in between the air filter cover and the engine

cover (Fig. 24). Turn the idle speed screw in, clockwise,

1/8 of a turn at a time (as needed) until the engine idles

smoothly.

NOTE: The blade should not Fig. 24

rotate when the engine idles.

3. If the blade rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as needed), to reduce idle

speed.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not and any of the following are true have the

unit serviced by a Sears or other qualified service dealer:

• the engine will not idle the engine hesitates or stalls on acceleration there is a loss of engine power

ROCKER ARM CLEARANCE This requires disassembly of the engine. If unsure or unqualified to perform this,

take the unit to a Sears or other qualified service dealer.

The engine must be cold when checking or adjusting the valve clearance. This task should be performed inside, in a clean, dust free area.

1. Remove the six (6) screws on the back of the engine cover with a Flat- head or T-25 Torx screwdriver (Fig. 25).

2. Disconnect the spark plug wire.

3. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.

4. Remove the engine cover (Fig. 25).

5. Clean dirt from around the rocker arm cover. Remove the screw holding the rocker arm cover with a large flat blade screwdriver or Torx T-25 bit

(Fig. 26). Remove the rocker arm cover and gasket.

6. Pull the starter rope slowly to bring the piston to the top of its travel, (known as top dead center). Check that:

The piston isat the top of its travel. This should be done by looking into the spark plug hole. (Fig. 26)

Both rocker arms move freely,

and both valves are closed View of the Rear Engine Cover
