_- 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.
Never refuel the machine indoors.
Never store the machine or fuel
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.
• 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.

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.

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

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.
10
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.

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.

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 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.
