_i, WARNING: This trimmer is equipped with an internal combustion engine and should

not be used on or near any unimproved forest-covered, brush-covered or grass-covered

land unless the engine's exhaust system is equipped with a spark arrester meeting ap-

plicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the state of California the above is required by law (Section 4442 of the California

Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest Sears service center (see the REPAIR PARTS section of this manual).

The operation of any trimmer can result in foreign objects thrown into

SAFETYGLASSES

the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your trimmer or performing any

adjustments or repairs. We recommend standard safety glasses or a

wide vision safety mask worn over spectacles.

&Look for this symbol to point out

important safety precautions. It means CAUTIONN! BECOME ALERT!N

YOUR SAFETY IS INVOLVED.

& WARNING: In order to prevent ac- cidental starting when setting up, trans-

porting, adjusting or making repairs,

always disconnect spark plug wire and

2 place wire where it cannot contact plug.

_i,WARNING: Engine exhaust, some

of its constituents, and certain vehicle

• Do not operate the machine while under the influence of alcohol or drugs.

• Never operate machine in wet grass. Al- ways be sure of your footing: keep a firm

hold on the handle and walk; never run.

• If the equipment should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibra- tion is generally a warning of trouble.

• Always wear safety goggles or safety glasses with side shields when oper- ating machine.

II. SLOPE OPERATION

Slopes are a major factor related to slip and fall accidents which can result insevere injury. All slopes require extra caution. If you feel

uneasy on a slope, do not trim it. DO:

• Trim across the face of slopes: never up and down. Exercise extreme caution

when changing direction on slopes.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

DO NOT:

• Do not trim near drop-offs, ditches or embankments. The operator could lose footing or balance.

• Do not trim excessively steep slopes.

• Do not trim on wet grass. Reduced foot-

ing could cause slipping.

TRIMMER HEAD DRIVE CONTROL Your trimmer is equipped with a trimmer

head drive control bar which will require the operator to be positioned behind the trimmer handle to operate the trimmer.

• Trimmer head rotation is controlled by holding the trimmer head control bar

down to the handle.

• Trimmer head rotation will stop when the control bar is released.

BEFORE STARTING ENGINE ADD OIL Your trimmer is shipped without oil in the

engine. For type and grade of oil to use, see "ENGINE" in the Maintenance section

of this manual. Ai_ CAUTION: DO NOT overfill engine with

oil, or it will smoke heavily from the muffler on startup.

1. Be sure trimmer is level.

2. Remove oil dipstick from oil fill spout.

3. You receive a container of oil with the

unit. Slowly pour the entire container down the oil fill spout into the engine.

4. Insert and tighten dipstick.

IMPORTANT:

• Check oil level before each use. Add oil

if needed. Fill to full line on dipstick.

• Change the oil after every 25 hours of

operation or each season. You may need to change the oil more often under dusty, dirty conditions.

ADD GASOLINE

• Fillfuel tank to bottom of gastank filler neck. Donotoverfill. Usefresh, clean,regular unleadedgasolinewith a

minimum of 87 octane. Do not mix oil

with gasoline. Purchase fuel in quanti- ties that can be used within 30 days to

assure fuel freshness.

_IL CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline

near an open flame.

J:IkCAUTION: Alcohol blended fuels

(called gasohol or using ethanol or methanol) can attract moisture which

leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the

fuel system should be emptied before storage of 30 days or longer. Empty the gas tank, start the engine and let it

run until the fuel lines and carburetor are empty. Use fresh fuel next season.

See Storage Instructions for additional

information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

NOTE: In cooler weather it may be

necessary to repeat priming steps. In warmer weather overpriming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat

priming steps.

TO STOP ENGINE

• To stop engine, move throttle control lever to STOP position.

TO START ENGINE

1. To start a cold engine, push primer three (3) times before trying to start. Use a firm push. This step is not usually neces-

sary when starting an engine which has already run for a few minutes.

2. Move throttle control lever to FAST position.

3. Hold upper handle firmly and pull starter handle quickly. Do not allow starter rope to snap back.

TRIMMING TIPS

• Set the throttle control in the FAST posi- tion. If the weeds or grass are tall and thick, operate the trimmer at a slower

walking speed.

• Frequently clean the underside of the trimmer to remove any grass build up. Keep top of engine around starter clear and clean of grass clippings and chaff.

This will help engine air flow and extend engine life.

• For best results and longer lasting line, use the ends of the line to do the cutting. This is easily done by moving slowly through very thick and heavy weeds.

• Use the left side of trimmer when trim- ming along fences, walls, flowerbeds

and other such objects.

• If trimmer lines become too short, it will take longer to complete the job. If trim-

mer lines are worn to less than half their original length, they should be replaced.

See "TO REPLACE TRIMMER LINE" in the Maintenance section of this manual.

• Trimmer head contact with concrete, as- phalt or other hard surfaces may cause premature wear of the ball on bottom of

trimmer head.

cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must

maintain trimmer as instructed in this

manual.

BEFORE EACH USE

1. Check engine oil level.

2. Check for loose fasteners.

3. Clean under engine cover.

Some adjustments will need to be made

periodically to properly maintain your unit. At least once a season, check to see if

you should make any of the adjustments described in the Service and Adjustments

LUBRICATION

To prolong the useful life of your trimmer, change engine oil as recommended in this

section of Owner's Manual,

section of this manual.

• At least once a year, replace the spark plug and replace air filter element. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.

IMPORTANT: Do not oil or grease plastic

wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the

life of the self- lubricating bearings. If you

feel they must be lubricated, use only a dry,

powdered graphite type lubricant sparingly.

TRIMMER

Always observe safety rules when per- forming any maintenance.

TIRES

• Keep tires free of gasoline, oil, or insect

control chemicals which can harm rub-

ber.

• Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

TRIMMER LINE

For best results, replace trimmer lines

when they have worn to half their original

length. Use .155 inch diameter trimmer line. Cut new trimmer line length to 18-3/4

inches. After new line is installed on

trimmer head, check all lines so they do

not vary more then one (1) inch in length.

This is important to make sure the trim-

mer head is balanced and will not vibrate

abnormally. _kWARNING: Use only the specified trimmer line. Do not use other materials

such as wire, string, rope, etc. Wire can

break off during trimming and become a

dangerous missile that can cause serious

injury.

TO CUT LINE TO PROPER LENGTH

NOTE: Trimmer line pre-cut to proper length is available for this unit; see the Repair Parts section of this manual. If trimmer line is purchased in bulk, it must be cut to 18=3/4 inches before using. Use

the built-in length guage as follows:

1. From front of trimmer, place the end of spooled trimmer line at the mark on the

side of the debris shield as shown.

2. Wrap trimmer line around front of chas- sis cover to other side and cut at the

"22" mark (your unit's width of cut).

TO REPLACE TRIMMER LINE

1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.

2. Remove worn trimmer line from line carrier plate.

3. Fold new, cut to length, trimmer line in half and insert folded end through carrier plate opening to back side of retainer clip.

4. With folded end of line at back side of retainer clip, pull line outward until line

is fully seated under the retainer clip.

5. Repeat on other side of carrier plate.

6. Check all lines to be sure they are the same length.

7. Reconnect spark plug wire to spark plug.

TEMPERATURE RANGE ANTiCiPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosityoils

(5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of

operation or at least once a year if the unit

is not used for 25 hours in one year. Check the crankcase oil level before

starting the engine and after each five (5) hours of continuous use. Tighten oil plug

securely each time you check the oil level. TO CHANGE ENGINE OIL

NOTE: Before tipping trimmer to drain oil, drain fuel tank by running engine until fuel tank is empty.

1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.

2. Remove engine oil cap; lay aside on a clean surface.

3. Tip trimmer on its side as shown and drain oil into a suitable container. Rock

trimmer back and forth to remove any oil trapped inside of engine.

4. Wipe off any spilled oil from trimmer or side of engine.

5. Fill engine with oil (See "ADD OIL" in the Operation section of this manual).

6. Replace engine oil cap.

7. Reconnect spark plug wire to spark plug.

AIR FILTER Your engine will not run properly and may

be damaged by using a dirty air filter. Replace the air filter cartridge every 100 hours of operation or every season, which-

ever occurs first. Service air cleaner more often under dusty conditions.

TO CLEAN AIR FILTER

1. Loosen screw and tilt cover to remove.

2. Carefully remove cartridge.

3. Clean by gently tapping on a flat sur- face. If very dirty, replace cartridge.

,_CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

• Turn trimmer on its side. Make sure air filter and carburetor are up. Clean the

underside of your trimmer by scraping to remove build-up of grass and trash.

• Clean engine often to keep trash from accumulating. A clogged engine runs

hotter and shortens engine life.

Keep finished surfaces and wheels free of all gasoline, oil, etc. We do not recommend using a garden

hose to clean trimmer unless the elec- trical system, muffler, air filter and car-

buretor are covered to keep water out. Water in engine can result in shortened engine life.

A WARNING: To avoid serious injury,

before performing any service and

adjustments:

1. Stop engine.

2. Make sure the rotating lines and all

moving parts have completely stopped.

3. Disconnect spark plug wire from spark

plug and place wire where it cannot come in contact with plug.

ENGINE ENGINE SPEED

Your engine speed has been factory set.

Do not attempt to increase engine speed

or it may result in personal injury. If you

believe that the engine is running too fast or too slow, take your unit to a Sears or other qualified service center for repair

and/or adjustment.

CARBURETOR

Your carburetor has a nonadjustable fixed

main jet for mixture control. If your engine

does not operate properly due to sus-

pected carburetor problems, take your unit to a Sears or other qualified service center for repair and/or adjustment.

IMPORTANT: Never tamper with the

engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs

adjusting, take your unit to a Sears or other qualified service center, which has

proper equipment and experience to make

any necessary adjustments.

Immediately prepare your trimmer for stor- age at the end of the season or if the unit

will not be used for 30 days or more.

TRIMMER

When trimmer is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dryarea.

1. Clean entire trimmer (See"CLEANING" in the Maintenance section of this manual).

2. Lubricate as shown in the Maintenance section of this manual.

3. Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.

4. Touch up all rusted or chipped paint surfaces; sand lightly before painting.

HANDLE

You can fold your trimmer handle for storage.

• Loosen handle knob enough to allow upper handle to be folded forward.

IMPORTANT: When folding the handle for storage or transportation, be sure to fold

the handle as shown or you may damage the control cables.

Handle knob

ENGINE FUEL SYSTEM iMPORTANT: It is important to prevent

gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose or tank during storage.

Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract

moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

• Empty the fuel tank by starting the en-

gine and letting it run until the fuel lines and carburetor are empty.

• Never use engine or carburetor cleaner

products in the fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix

ratio found on stabilizer container. Run engine at least 10 minutes after adding

stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank

and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual).

CYLINDER

1. Remove spark plug.

2. Pour one ounce (29 ml) of oil through

spark plug hole into cylinder.

3. Pull starter handle slowly a few times

to distribute oil.

4. Replace with new spark plug.

OTHER

• Do not store gasoline from one season

to another.

• Replace your gasoline can if your can

starts to rust. Rust and/or dirt in your gasoline will cause problems.
