_I,WARNmNG: 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).
SAFETYGLASSES
The operation of any trimmer can result in foreign objects thrown into 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 a wide vision safety mask over
spectacles or standard safety glasses.
L GENERAL OPERATmON
* 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 oper- ate 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
absolutely necessary. Always look down and behind before and while 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 de-
vices. This unit is designed for line trim-
mer use only. Use of other accessories or attachments 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.
Always 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 operating
machine.
H. SLOPE OPERATmON Slopesarea majorfactorrelatedtoslip
andfallaccidentswhichcan resultin
severeinjury.All slopesrequireextracau- tion. Ifyoufeel uneasyona 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.
HL CHmLDREN
Tragic accidents can occur if the operator
is not alert to the presence of children. 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 and down for small children. Never allow children to operate the ma-
chine. Use extra care when approaching blind
corners, shrubs, trees, or other objects that may obscure vision.
mY. 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 the engine running. Allow en- gine to cool before refueling. Do not
smoke.
Never refuel the machine indoors.
Never store the machine or fuel con-
tainer inside where there is an open flame, such as a water heater.
Move away from fueling site before
starting engine.
Never run a machine 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 plug to prevent accidental 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.
Stop and inspect the equipment if you strike an object. Repair, if necessary,
before restarting.
Do not change the engine governor set- ting or overspeed the engine.
Clean and replace safety and instruction
decals as necessary.
&Look for this symbol to point out important safety precautions. It means
CAUTION!!! BECOME ALERT!!! 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
place wire where it cannot contact spark plug. &WARNmNG: 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. _, CAUTmON: 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.

SAFETYGLASSES
The operation of any trimmer can result
in foreign objects being thrown into the
eyes, which can result in severe eye dam-
age. Always wear safety glasses or eye
shields while operating your trimmer or
performing any adjustments or repairs. We recommend a wide vision safety mask over
spectacles or standard safety glasses.
HOW TO USE YOUR TRmMMER
ENGmNE SPEED
The engine speed is controNed by a throttle located on the side of the upper
handle. Fast position is for starting and normal trimming. Slow is for light trimming
and fuel economy. Stop is for stopping the
engine.
TO ADJUST TRIMMING HEmGHT _CAUTmON: Stop the engine and wait for
all moving parts to stop. Disconnect spark
plug wire from spark plug and place wire
where it cannot come in contact with plug. The height of cut can be set to six (6) dif-
ferent positions ranging from 1-1/2 inches to 3 inches. Recommended cutting height
for the average yard is 2 inches.
1. To adjust trimming height, push in the locking plate tab and move trimmer
head up or down to desired position.
2. Release tab and be sure head is locked into one of the six (6) height
positions.

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 ENGmNE
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. Youreceivea 20 oz.containerof oil with theunit. Slowly pour3/4 (15oz.)
oftheoil from thecontainerdownthe oilfill spout intothe engine.
4. Waitone minuteto allowoil tosettle. Insertandtightendipstick,then re-
moveitto checkoil level.
5. Continueaddingsmallamountsof oiland recheckingthe dipstick until it

6. Alwaysbesureto retightenoildipstick beforestartingengine.
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 GASOUNE
Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quantities that can be used within 30 days to assure fuel fresh-
ness.
AI:_WARNmNG: Experience indicates that
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. Al_ CAUTmON: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use
gasoline near an open flame.

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 necessary when starting an
engine which has already run for a few
minutes.
2. Move throttle control lever to fast posi- tion.
3. Hold upper handle firmly and pull starter handle quickly. Do not allow
starter rope to snap back.
TO STOP ENG(NE
To stop engine, move throttle control
lever to stop position.
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 m_ before
controu
Throttle -'_\
Starter '_' "_!_!, // handle _,.. /_L
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. See "TO REMOVE ENGINE
COVER" in the Maintenance section of this manual.
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, fiowerbeds
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.

GENERAL RECOMMENDATmONS
The warranty on this trimmer does not 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.
Some adjustments will need to be made periodically to properly maintain your unit.
All adjustments in the Service and Adjust-
ments section of this manual should be
checked at least once each season.
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.
Follow the maintenance schedule in this manual.
BEFORE EACH USE
1. Check engine oil level.
2. Check for loose fasteners.
3. Clean under engine cover. LUBRmCATmON
To pro{ong the useful life of your trimmer, change engine oil as recommended in this
section of Owner's Manual.
mMPORTANT: 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.

TR(MMERL(NE
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.
AWARNmNG: 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).

SPARK PLUG Replace spark plugs 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 "PRODUCT SPECIFICATIONS"
in Maintenance section of this manual.
mMPORTANT: For best performance, keep
trimmer free of built-up grass and trash.
Clean the underside of your trimmer after
each use. ACAUTmON: Disconnect spark plug wire
from spark plug and place wire where it cannot come in contact with the spark
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.
