Eye Protection
___
Cut from your right to your left,
Always tap the trimmer head on a
grassy area. Tapping on surfaces
such as concrete or asphalt can
cause excessive wear to the trimmer
head.
If the line is worn down to 2 in. (5 cm)
or less, more than one tap will be required to obtain the most efficient line
length.
_L, WARNING:
_WARNING:
Always wear eye
protection. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face
and cause blindness or other serious
injury.
Do not run the engine at a higher
speed than necessary. The cutting
line will cut efficiently when the engine
is run at less than full throttle. At lower
speeds, there is less engine noise and
vibration. The cutting line will last
longer and will be less likely to "weld"
onto the spool.
Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.
To stop engine:
• Release the throttle trigger.
• Move the ON/OFF switch to the OFF
position.
TRIMMER
Use only 0.080"
(2 mm) diameter line. Other sizes of
line will not advance properly and can
cause serious injury. Do not use other
materials such as wire, string, rope,
etc. Wire can break off during cutting
and become a dangerous missile that
can cause serious injury.
CUTTING METHODS
Use minimum speed and do not
crowd the line when cutting around
hard objects (rock, gravel, fence
posts, etc.), which can damage the
trimmer head, become entangled in
the line, or be thrown causing a serious hazard.
• The tip of the line does the cutting.
You will achieve the best performance and minimum line wear by not
crowding the line into the cutting
area. The right and wrong ways are
shown below.
Tip of the Line
Line Crowded Into
Does The Cutting
Work Area
LINE ADVANCE
The trimmer line will advance approximately 2 in. (5 cm) each time the bottom of the trimmer head is tapped on
the ground with the engine running at
full throttle.The most efficient line
length is the maximum length allowed
by the line limiter.
Always keep the shield in place when
the tool is being operated.
To Advance Line:
• Operate the engine at full throttle.
• Hold the trimmer head parallel to
and above the grassy area.
• Tap the bottom of the trimmer head
lightly on the ground one time. Approximately 2 in. (5 cm) of line will
be advanced with each tap.

• The line will easily remove grass
and weeds from around walls,
fences, trees and flower beds, but it
also can cut the tender bark of trees
or shrubs and scar fences. To help
avoid damage especially to delicate
vegetation or trees with tender bark,
shorten line to 4-5 in. (10-13 cm)
and use at less than full throttle.
• For trimming or scalping, use less
than full throttle to increase line life
and decrease head wear, especially:

CARBURETOR
ADJUSTMENT
,_ILWARNING:
The trimmer
head
will be spinning during most of this
procedure. Wear your protective
equipment and observe all safety precautions. After making mixture adjustments, recheck idle speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the carburetor. If you require further assistance or are unsure about performing
this procedure, call our customer assistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel filter, or flooding may give the impression of an improperly adjusted carburetor. Check these conditions before
adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the following conditions:
• Engine will not idle. See IDLE SPEED
under adjusting procedure.
• Engine dies or hesitates instead of
accelerating. See ACCELERATION
CHECK under adjusting procedure.
• Loss of cutting power. See MIXTURE
ADJUSTMENT under adjusting
procedure.
There are two adjustment screws on
the carburetor, a mixture screw and an
idle speed screw.

ADJUSTING
PROCEDURE
CAUTION:
Do not force plastic ]imiter
caps on screws beyond the built-in
stops or damage will occur. Be sure
trimmer line is extended to the maximum length allowed by the line limiter
blade.
Initial Settings:
1. Turn mixture screw counterclockwise until it stops.
2. Turn the idle speed screw clockwise
until it stops. Now turn counterclockwise 4 1/2 turns.
3. Start engine, cut grass for 3 minutes, then proceed to adjust screws
according to the instructions below.
If engine performance at initial settings is acceptable, no further adjustments are necessary. If engine
does not start, refer to TROUBLESHOOTING TABLE. If still unable to
remedy situation, call
1-800-235-5878.
Idle Speed
Allow engine to idle. Adjust speed until
engine runs without stalling.
• Turn idle speed screw clockwise to
increase engine speed if engine stalls
or dies.
• Turn idle speed screw counterclockwise to decrease engine speed.
No further adjustments are necessary
if performance is satisfactory.
Mixture Adjustment
CAUTION:
Do not operate engine at
full throttle for prolonged periods while
making adjustments as damage to the
engine can occur. Adjust the mixture
screw 1/16 of a turn at a time. A 1/16
turn is about the width of the slot in the
top of the screw.
• Turn the mixture screw clockwise
until the engine has good power
with no hesitation while cutting.
Do not adjust by sound or speed,
but judge by how well the engine
performs while cutting.
• Turn the mixture screw counterclockwise if the engine has speed
but dies or lacks power while cutting.
After completing adjustments, check
for acceleration. Reset if necessary.

Prepare unit for storage at end of season or if it will not be used for 30 days
or more.
If your unit is to be stored for a period
of time:
• Clean the entire unit before lengthy
storage.
• Store in a clean dry area.
• Lightly oil external metal surfaces.
FUEL SYSTEM
Under FUELING ENGINE in the OPERATION section of this manual, see message labeled IMPORTANT regarding
the use of gasohol in your engine.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
container. Run engine at least 5 minutes after adding stabilizer.
Craftsman 40:1,2-cycle
engine oil (air
cooled) is already blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to
your fuel tank.
INTERNAL ENGINE
• Remove spark plug and pour 1 teaspoon of 40:1,2-cycle
engine oil (air
cooled) through the spark plug
opening. Slowly pull the starter rope
8 to 10 times to distribute oil.
• Replace spark plug with new one of
recommended
type and heat range.
• Clean air filter.
• Check entire unit for loose screws,
nuts, and bolts. Replace any damaged, broken, or worn parts.
• At the beginning of the next season,
use only fresh fuel having the proper
gasoline to oil ratio.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if it starts
to rust.

OWNER'S
WARRANTY
RESPONSIBILITIES: As the lawn and garden
equipment engine owner, you are responsible for the performance of the
required maintenance listed in your
Owner's Manual. Sears recommends
that you retain all receipts covering
maintenance on your lawn and garden
equipment engine, but Sears cannot
deny warranty solely for the lack of receipts or for your failure to ensure the
performance of all scheduled maintenance.
As the lawn and garden
equipment engine owner, you should
be aware that Sears may deny you
warranty coverage if your lawn and
garden equipment engine or a part of
it has failed due to abuse, neglect, improper maintenance, unapproved
modifications, or the use of parts not
made or approved by the original
equipment manufacturer.
You are responsible for presenting your lawn
and garden equipment engine to a
Sears authorized repair center as
soon as a problem exists. Warranty
repairs should be completed in a reasonable amount of time, not to exceed
30 days. If you have any questions
regarding your warranty rights and responsibilities, you should contact your
nearest authorized service center or
call Sears at 1-800-469-4663.
WARRANTY COMMENCEMENT
DATE:
The warranty period begins on the
date the lawn and garden equipment
engine is purchased.
LENGTH OF
COVERAGE: This warranty shall be
for a period of two years from the initial date of purchase. WHAT IS COVERED: REPAIR OR REPLACEMENT
OF PARTS. Repair or replacement of
any warranted part will be performed
at no charge to the owner at an approved Sears servicing center. If you
have any questions regarding your
warranty rights and responsibilities,
you should contact your nearest authorized service center or call Sears at
1-800-469-4663.
WARRANTY PERIOD: Any warranted
scheduled for replacement as required maintenance, or which is
scheduled only for regular inspection
to the effect of "repair or replace as
necessary" shall be warranted for 2
years. Any warranted part which is
scheduled for replacement as required maintenance shall be warranted for the period of time up to the
first scheduled replacement point for
that part. DIAGNOSIS: The owner
shall not be charged for diagnostic labor which leads to the determination
that a warranted part is defective if the
diagnostic work is performed at an approved Sears servicing center. CONSEQUENTIAL
DAMAGES: Sears
may be liable for damages to other
engine components caused by the
failure of a warranted part still under
warranty. WHAT IS NOT COVERED:
All failures caused by abuse, neglect,
or improper maintenance are not covered. ADD-ON OR MODIFIED
PARTS: The use of add-on or modified
parts can be grounds for disallowing a
warranty claim. Sears is not liable to
cover failures of warranted parts
caused by the use of add-on or modified parts. HOW TO FILE A CLAIM: If
you have any questions regarding
your warranty rights and responsibilities, you should contact your nearest
authorized service center or call Sears
at 1-800-469-4663.
