WARNING: This trimmer is equipped with an internal com bus tion engine and
should not be used on or near any un im proved forest-covered, brush-covered or grasscov ered land unless the engine’s exhaust system is equipped with a spark arrester
meeting applicable local or state laws (if any). If a spark arrester is used, it should be
main tained 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).
SAFETY RULES
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 per form ing any
adjustments or repairs. We rec om mend standard safety glasses or a
wide vision safety mask worn over spectacles.
Look for this symbol to point out
im por tant safety precautions. It means
CAU TION!!! BECOME ALERT!!!
YOUR SAFE TY IS INVOLVED.
WARNING: In order to prevent ac ci-
den tal starting when setting up, trans port ing, ad just ing or making repairs, always
dis con nect spark plug wire and place wire
where it can not contact plug.

WARNING: Engine exhaust, some
of its constituents, and certain vehicle
com po nents contain or emit chem i cals
known to the State of Cal i for nia to cause
can cer and birth defects or oth er re produc tive harm.
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
instructions on the machine and in the
manual before starting. Be thor ough ly
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 hous es, 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 children 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 barefoot 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 approved by the manufacturer.
• Never use blades, wire, or flailing devices.
This unit is designed for line trimmer use
only. Use of other ac ces so ries 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.
Vibration is generally a warning of
trouble.
• Always wear safety goggles or safety
glasses with side shields when op er at 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.
3
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 footing could cause slipping.
III. CHILDREN
Tragic accidents can occur if the operator is not alert to the presence of children. Chil dren are often attracted to the
ma chine 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 chil dren.
• 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 ap proved con tain er.
- 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 in doors.
- Never store the machine or fuel
con tain er 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 ci den tal 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 setting or overspeed the engine.
• Clean and replace safety and in struc tion
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 “EN GINE” in the Maintenance section
of this manual.
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
changing oil you may need 20 oz.
4. Insert and tighten dipstick.
IMPORTANT:
• Check oil level before each use. Add
oil if needed. Fill to full line on dipstick.
Use ear
protectors to
avoid
damage to hearing.
8
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. Purchase fuel in quan ti ties 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 for ma tion 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 stor age 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 In struc tions for
additional information. Never use engine or
carburetor cleaner products in the fuel tank
or permanent damage may occur.

TRIMMING TIPS
• 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
trimmer 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.

MAINTENANCE
GENERAL RECOMMENDATIONS
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.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Ad just ments
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 mix ture
and help your engine run better and
last longer.
TRIMMER
Always observe safety rules when per form ing any main te nance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemi cals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
• 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.
LUBRICATION
To prolong the useful life of your trimmer,
change engine oil as recommended in
this section of Owner’s Manual.
IMPORTANT: Do not oil or grease plastic
wheel bearings. Vis cous lu bri cants will
at tract dust and dirt that will short en the life
of the self- lu bri cat ing bearings. If you feel
they must be lu bri cat ed, use only a dry,
pow dered graph ite type lu bri cant spar ing ly.
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 trimmer head is balanced
and will not vibrate ab nor mal ly.
10
WARNING: Use only the specified
trimmer line. Do not use other ma te ri als
such as wire, string, rope, etc. Wire can
break off during trimming and become a
dan ger ous 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
chassis cover to other side and cut
at the “22” mark (your unit’s width of
cut).

come in contact with spark plug.
2. Remove worn trimmer line from line
carrier plate.
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.
11
* NOTE: An oil change is not required but
if you desire to change the oil follow the
procedure below.
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 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 op er a tion or every season,
which ev er occurs first. Service air cleaner
more often under dusty conditions.
4. Install cartridge, then replace cover.

MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
SPARK ARRESTOR
Your muffler is equipped with a special spark
arrestor screen which restricts the flow of hot
particles out of the muffler. Hot particles my
cause fire if they contact dry and combustible material. Never operate this equipment
without the spark arrestor in place.
The spark arrestor screen should be cleaned
annually by removing the arrestor from the
engine and brushing it with a wire brush. A
blocked screen may cause the engine to
run hot and lead to engine failure.
TO REMOVE THE SPARK ARRESTOR:
Using a 1/4" wrench or nut driver remove
the (1) screw that retains the arrestor to
the muffler. Slide arrestor screen out of
the muffler exhaust tube.
Inspect the screen for any plugging or
damage. If the screen is plugged, brush
with a stiff wire brush. A damaged arrestor
should be replaced.
Installation is the reverse of removal,
tighten screw to 24 in-lbs (3.7 Nm). Do
not overtighten.
TO CLEAN AIR FILTER
1. Remove cover.
2. Carefully remove cartridge.
3. Clean by gently tapping on a flat surface. If very dirty, replace car tridge.
CAUTION: Pe tro leum solvents, such
as ker o sene, are not to be used to clean
car tridge. They may cause de te ri o ra tion of
the cartridge. Do not oil car tridge. Do not
use pres sur ized air to clean or dry car tridge.

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 “PROD UCT SPEC I FI CA TIONS” 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 each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with 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.
• 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 tri cal system, muffler, air filter and carburetor are covered to keep water out.
Water in engine can result in shortened
engine life.
SERVICE AND ADJUSTMENTS
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 the spark 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 pect-
ed 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. Over speed ing
