_- 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
SAFETY GLASSES
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.
ALook for this symbol to point out
important safety precautions. It means CAUTION!!! BECOME ALERT!!!
YOUR SAFETY IS INVOLVED.
A 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.
,AWARNING: Engine exhaust, some
of its constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm. _I, CAUTION: Muffler and other engine
parts become extremely hot during
operation and remain hot after engine has
stopped. To avoid severe burns on contact,
stay away from these areas.
I. GENERAL OPERATION
Read, understand, and follow all instruc- tions on the machine and in the manual
before starting. Be thoroughly familiar with the controls and the proper use of the machine before starting.
Do not put hands or feet near or under rotating parts.
Keep all parts of your body away from muffler and spinning line. A hot muffler
can cause serious burns.
Only allow responsible individuals, who
are familiar with the instructions, to operate the machine.
Stay away from breakable objects, such
as house windows, auto glass, green-
houses, etc.
Clear the area of objects such as rocks,
toys, wire, bones, sticks, etc., which could be picked up and thrown by the spinning lines.
Be sure the area is clear of other people before trimming, particularly small chil-
dren and pets. Stop machine if anyone enters the area.
Wear appropriate clothing such as a long-sleeved shirt or jacket. Also wear long trousers or slacks. Do not wear
shorts.
Do not wear loose clothing which could
get caught in this equipment.
Do not operate the machine when bare-
foot or wearing open sandals. Always wear work gloves and sturdy footwear.
Leather work shoes or short boots work
well for most people. These will protect the operator's ankles and shins from
small sticks, splinters, and other debris, and improve traction.
Do not pull machine backwards unless ab- solutely necessary. Always Iookdown and behind before andwhile moving backwards.
Do not operate the machine without proper guards, plates or other safety
protective devices in place.
See manufacturer's instructions for proper operation and installation of
accessories. Only use accessories ap- proved by the manufacturer.
Never use blades, wire, or flailing devices. This unit is designed for line trimmer use only. Use of other accessories or attach- ments will increase the risk of injury.
Stop the rotating trimmer head when crossing gravel drives, walks, or roads. Wait for the cutting lines to stop rotating.
Stop the engine (motor) whenever you leave the equipment and allow it to cool, before cleaning, repairing or inspecting
the unit. Be sure the trimmer head and all moving parts have stopped.
Operate only in daylight or good artificial light.
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 operat- ing machine.
II. SLOPE OPERATION
Slopes are a major factor related to slip and fall accidents which can result in severe 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.
3
ill. CHILDREN Tragic accidents can occur if the opera-
tor is not alert to the presence of chil- dren. Children are often attracted to the
machine and the trimming activity. Never assume that children will remain where
you last saw them.
Keep children out of the trimming area and under the watchful care of another
responsible adult.
Be alert and turn machine off if children enter the area.
Before and while moving backwards,
look behind & down for small children.
Never allow children to operate the
machine.
Use extra care when approaching blind corners, shrubs, trees, or other objects
that may obscure vision.
IV. SERVICE
Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.
- Use only an approved container.
- Never remove gas cap or add fuel with
with the engine running. Allow engine to cool before refueling. Don't smoke.

container inside where there is an open flame, such as a water heater.
Move away from fueling site before
starting engine.
Never run trimmer inside a closed area.
Never make adjustments or repairs with the engine (motor) running. Disconnect the spark plug wire, and keep the wire
away from the spark plug to prevent ac- cidental starting.
Keep nuts and bolts, especially trimmer
head and engine bolts, tight and keep equipment in good condition.
Never tamper with safety devices.
Check their proper operation regularly.
Keep machine free of grass, leaves, or
other debris buildup. Clean oil or fuel spillage. Allow machine to cool before
cleaning or storing.

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.
A CAUTION: DO NOT overfill engine with
oil, or it will smoke on startup.
1. Be sure trimmer is level and area around oil fill is clean.
2. Remove oil dipstick from oil fill spout. Make sure that rim of spout is clean.
3. You receive a container of oil with the unit. Slowly pour the entire container
down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the
manufacturers 100% quality testing. When
8 changing oil you may need 20 oz.
4. Insertandtightendipstick. IMPORTANT:
Check oil level beforeeach use. Addoil
if needed. Fillto full lineondipstick.
Changethe oil afterevery 25 hoursof
operationor each season. You may
needto change theoil moreoftenunder
dusty,dirty conditions.
ADD GASOLINE
Fill fuel tank to bottom of tank filler neck.
Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline. Pur- chase fuel in quantities that can be used
within 30 days to assure fuel freshness.
& CAUTION: 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. Drain
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.
ILCAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.

TRIMMING TIPS
Set the throttle control in the FAST pos=-
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.

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

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
,_l_normally
WARNING: 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-viscosity oils (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.
Container
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: Petroleum solvents, such as kerosene, are not to be used to clean
cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge.
4. Install cartridge, then replace cover making sure the tabs are aligned with
the slots in the back plate. Fasten
screw securely.

MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage. SPARK PLUG
Replace spark plug at the beginning of each mowing season or after every 100 hours of operation, whichever occurs
first. Spark plug type and gap setting are shown in the "PRODUCT SPECIFIC-
ATIONS" section of this manual. CLEANING
iMPORTANT: For best performance, keep trimmer free of built-up grass and trash. Clean the underside of your trimmer after
12each use.
,_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.
