completely and securely assembled.
Always replace bar, chain, hand
guard, chain brake, or other parts immediately if they become damaged,
broken, or are otherwise removed.
MAINTAIN
YOUR
SAW IN GOOD
WORKING ORDER
• Have all chain saw service performed by a qualified service dealer
except the items listed in the MAINTENANCE section of this manual.
• Make certain the saw chain stops
moving when the throttle trigger is
released. For correction, refer to
CARBURETOR ADJUSTMENTS.
• Keep the handles dry, clean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
tightened.
• Nonconforming replacement components or the removal of safety devices
may cause damage to the unit and
possible injury to the operator or bystanders. Use only Craftsman accessories and replacement parts as recommended. Never modify your saw.
• Maintain chain saw with care.
• Keep unit sharp and clean for better
and safer performance.
• Follow instructions for lubricating and
changing accessories.
• Check for damaged parts. Before further use of the chain saw, a guard or
other part that is damaged should be
carefully checked to determine that it
will operate properly and perform its
intended function. Check for alignment
of moving parts, binding of moving
parts, breakage of parts, mounting and
any other conditions that may affect its
operation. A guard or other part that is
damaged should be properly repaired
or replaced by a Sears Service Center
unless otherwise indicated elsewhere
in the instruction manual.
• When not in use, chain saws should
be stored in a dry, high or locked-up
place out of the reach of children.
• When storing saw, use a scabbard or
carrying case.
HANDLE FUEL WITH CAUTION
• Do not smoke while handling fuel or
while operating the saw.
• Eliminate all sources of sparks or
flame in areas where fuel is mixed or
poured.
• Mix and pour fuel in an outdoor area
and use an approved, marked container for all fuel purposes. Wipe up
all fuel spills before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting.
• Turn the engine off and let saw cool
in a non-combustible
area, not on
dry leaves, straw, paper, etc. Slowly
remove fuel cap and refuel unit.
• Store the unit and fuel in a cool, dry
well ventilated space where fuel vapors cannot reach sparks or open
flames from water heaters, electric
motors or switches, furnaces, etc.
GUARD AGAINST
KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.

Kickback Path
Avoid Obstructions
Clear The Working Area
Z_
LI_ WARNING:
Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood closes in and pinches the saw
chain in the cut. Contacting a foreign
object in the wood can also result in
loss of chain saw control.
•
Rotational
Kickback
can occur
when the moving chain contacts an
object at the upper tip of the guide
bar. This contact can cause the
chain to dig into the object, which
stops the chain for an instant. The
result is a lightning fast, reverse
reaction which kicks the guide bar
up and back toward the operator.
•
Pinch-Kickback
can occur when
the the wood closes in and pinches
the moving saw chain in the cut
along the top of the guide bar and
the saw chain is suddenly stopped.
This sudden stopping of the chain
results in a reversal of the chain
force used to cut wood and causes
the saw to move in the opposite direction of the chain rotation. The
saw is driven straight back toward
the operator.
•
Pull-In can occur when the moving
chain contacts a foreign object in
the wood in the cut along the bottom of the guide bar and the saw
chain is suddenly stopped. This
sudden stopping pulls the saw forward and away from the operator
and could easily cause the operator to lose control of the saw.
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can happen.
With a basic understanding of kickback, you can reduce the element of
surprise which contributes to accidents.
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keep working area free from obstructions such as other trees, branches,
rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your saw
chain could hit while cutting.
• When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
• Keep saw chain sharp and properly
tensioned. A loose or dull chain can
increase the chance of kickback. Follow manufacturer's chain sharpening
and maintenance instructions. Check
tension at regular intervals, but never
with engine running. Make sure chain
brake nuts are securely tightened.
• Begin and continue cutting at full
speed. If the chain is moving at a
slower speed, there is greater chance
of kickback occurring.
• Use extreme caution when reentering
a cut.
• Do not attempt cuts starting with the
tip of the bar (plunge cuts).
• Watch for shifting logs or other forces
that could close a cut and pinch or fall
into chain.
• Use the specified Reduced-Kickback
Guide Bar and Low-Kickback Chain.
Avoid Pinch-Kickback:
• Be extremely aware of situations or
obstructions that can cause material
to pinch the top of or otherwise stop
the chain.
• Do not cut more than one log at a
time.
• Do not twist saw as bar is withdrawn
from an undercut when bucking.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or wood.
Never use metal to hold the cut open.

SAFETY
FEATURES KICKBACK.
action which throws the bar and rotat,_ WARNING:
The following features
are included on your saw to help reduce
hazard of kickback; however, such features will not totally eliminate this danger.
Do not rely only on safety devices. Follow all safety rules to help avoid kickback and other forces which can result
in serious injury,
• Front Hand Guard: designed to reduce
the chance of your left hand contacting the chain if your hand slips off the
front handlebar.
• Position of front and rear handlebars:
designed with distance between handles and "in-line" with each other. The
spread and "in-line" position of the
hands provided by this design work
together to give balance and resistance in controlling the pivot of the
saw back toward the operator if kickback occurs.
• Reduced-Kickback Guide Bar: designed with a small radius tip which
reduces the size of the kickback danger zone on the bar tip. This type bar
has been demonstrated to significantly
reduce the number and seriousness of
kickbacks when tested in accordance
with ANSI B175.1.

ing chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the
danger zone with any hard object.
Kickback can also be caused by
pinching the saw chain along the top
of the guide bar. This action may push
the guide bar rapidly back toward the
operator. Either of these events may
cause you to lose control of the saw
which could result in serious injury or
even death. DO NOT RELY UPON ANY
OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced-kickback
guide
bars and low-kickback
saw chains reduce the chance and magnitude of
kickback and are recommended.
Your
saw has a low kickback chain and bar
as original equipment.
Repairs on a
chain brake should be made by an authorized Sears Service Center. Take
your unit to the place of purchase or to
your nearest Sears Service Center.
• Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
• Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
• Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.
SAFETY NOTICE: Exposure to vibrations through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to
circulation disorders or abnormal swelling. Prolonged use in cold weather has
been linked to blood vessel damage in
otherwise healthy people. If symptoms

OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION in the MAINTENANCE
section.
• Cut wood only. Do not cut metal,
plastics, masonry, non-wood building
materials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
• Practice cutting a few small logs using the following steps. This will help
you get the "feel" of using your saw
before you begin a major sawing operation.
• Squeeze the throttle trigger and allow the engine to reach full speed
before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the
entire time you are cutting.
• Allow the chain to cut for you. Exert
only light downward pressure.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wear can occur.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop engine before setting saw down.

FELLING
WARNING:
TECHNIQUES
Check for broken or
dead branches which can fall while cutting causing serious injury. Do not cut
near buildings or electrical wires if you
do not know the direction of tree fall, nor
cut at night since you will not be able to
see well, nor during bad weather such
as rain, snow, or strong winds, etc.
• Carefully plan your sawing operation
in advance.
• Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill
after it is felled.
• Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions include:
• The wind direction and speed.
• The lean ofthe tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the direction of tree lean.
• Weight and branches on one side.
• Surrounding trees and obstacles.
• Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator.
• Make sure there is enough room for
the tree to fall. Maintain a distance of
2-1/2 tree lengths from the nearest
person or other objects. Engine
noise can drown out a warning call.
• Remove dirt, stones, loose bark,
nails, staples, and wire from the tree
where cuts are to be made.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend to fall in
the direction of the notch.

• After removing the wood from the
notch, make the felling cut on the opposite side of the notch. This is done
by making a cut about two inches
higher than the center of the notch.
This will leave enough uncut wood between the felling cut and the notch to
form a hinge. This hinge will help prevent the tree from falling in the wrong
direction.

NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of
fall. To avoid kickback and chain
damage, use wood or plastic wedges,
but never steel or iron wedges.
• Be alert to signs that the tree is ready
to fall: cracking sounds, widening of
the felling cut, or movement in the upper branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
• DO NOT use your saw to cut down a
partially fallen tree. Be extremely
cautious with partially fallen trees
that may be poorly supported. When
a tree doesn't fall completely, set the
saw aside and pull down the tree
with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
,_k WARNING:
Do not stand on the
log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.
IMPORTANT POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• Use a sawhorse to cut small logs.
Never allow another person to hold
the log while cutting and never hold
the log with your leg or foot.
• Do not cut in an area where logs,
limbs, and roots are tangled. Drag
logs into a clear area before cutting
them by pulling out exposed and
cleared logs first.
BUCKING TECHNIQUES
A
m_, WAR NI N G: If saw becomes
pinched or hung in a log, don't try to
force it out. You can lose control of the
saw resulting in injury and/or damage to
the saw. Stop the saw, drive a wedge of
plastic or wood into the cut until the saw
can be removed easily. Restart saw and
carefully reenter the cut. Do not use a
metal wedge. Do not attempt to restart
your saw when it is pinched or hung in a
log.
Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting
begins on the top side of
the log with the bottom of the saw
against the log. When overcutting use
light downward pressure.

BUCKING WITHOUT A SUPPORT
• Overcut through 1/3 of the diameter
of the log.
• Roll the log over and finish with a
second overcut.
• Watch for logs with a compression
side to prevent the saw from pinching. See illustrations above for cutting logs with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is always on
the compression side of the log. (Refer to the illustrations below for your
first and second cut).
• Your first cut should extend 1/3 of the
diameter of the log.
• Finish with your second cut.

Be alert for and
guard against kickback. Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when limbing or pruning. Allowing such contact can result in serious injury.
,_WARNING:
Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
• Watch out for springpoles.
Springpoles are small size limbs
which can whip toward you, or pull
you off balance. Use extreme caution when cutting small size limbs.
• Be alert for springback from any
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Frequently clear branches out of the
way to avoid tripping over them.
LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.
• Keep the tree between you and the
chain.
• Remove larger branches with the
cutting techniques described in

GENERAL RECOMMENDATIONS
The warranty on this unit does not cover items that have been subjected to
operator abuse or negligence. To receive full value from the warranty, the
operator must maintain unit as instructed in this manual. Various adjustments
will need to be made periodically to
properly maintain your unit.
• Once a year, replace the spark plug,
air filter element, and check guide bar
and chain for wear. A new spark plug
and air filter element assures proper
air-fuel mixture and helps your engine
run better and last longer.
CHECK FOR DAMAGED OR
WORN PARTS

,i_ WARNING:
Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
Chain tension is very important.
Chains stretch during use.
This is especially true during the first
few times you use your saw. Always
check chain tension each time you use
and refuel your saw.
1. Use the screwdriver end of the
chain adjustment tool (bar tool) to
move chain around guide bar to
ensure kinks do not exist. The
chain should rotate freely.

7.
8.
9.
Use the screwdriver end of the bar
tool to move chain around guide bar.
If chain does not rotate, it is too
tight. Slightly loosen chain brake
nuts and loosen chain by turning
the adjusting screw counterclockwise. Retighten chain brake nuts.
If chain is too loose, it will sag below the guide bar. DO NOT operate
the saw if the chain is loose.
WARNING:
If the saw is operated
with a loose chain, the chain could
jump offthe guide bar and result in serious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
After each use, ensure ON/STOP
switch is in the STOP position, then
clean all sawdust from the guide bar
and sprocket hole.

CLEAN AIR FILTER
A dirty air filter decreases the life and
performance of the engine and increases fuel consumption and harmful
emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of operation, whichever comes first. Clean
more frequently in dusty conditions. A
used air filter can never be completely
cleaned. It is advisable to replace your
air filter with a new one after every 50
hours of operation, or annually, whichever comes first. To clean filter:
1. Loosen 3 screws on cylinder
cover.
2. Remove cylinder cover.
3. Remove air filter.
4. Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstalling.
5. Lightly oil air filter before installing to
improve the efficiency of air filter.
Use 2-cycle engine oil or motor oil
(SAE 30). Squeeze excess oil from
filter.
6. Reinstall air filter.
7. Reinstall cylinder cover and 3
screws. Tighten securely.

,_ik WARNING:
The chain will be
moving during most of this procedure.
Wear your protective equipment and
observe all safety precautions. During
the low speed mixture adjustment recheck idle speed after each turn of the
screw. The chain must not move at 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, 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:
• Chain moves at idle. See IDLE
SPEED-T under adjusting procedure.
• Saw will not idle. See IDLE SPEED-T
and LOW SPEED MIXTURE-L under
adjusting procedure.
• Engine dies or hesitates when it
should accelerate. See ACCELERATION CHECK under adjusting
procedure.
• Loss of cutting power. See HIGH
SPEED MIXTURE - H under adjusting
procedure.
There are three adjustment screws on
the carburetor. They are labeled H, L,
and T. They are located in the area just
above the primer bulb.
ADJUSTING
PROCEDURE
CAUTION:
Do not force plastic limiter
caps on screws beyond the built-in
stops or damage will occur.
Initial Settings
1. Turn both mixture screws (L and H)
counterclockwise
until they stop.
2. Turn the idle speed screw (T)
clockwise until it stops. Then turn it
counterclockwise
4 and 1/2 turns.
3. Start engine and let it run 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 the
TROUBLESHOOTING TABLE. If still
unable to remedy situation, call
1-800-235-5878.
Idle Speed-T
Allow engine to idle. If the chain
moves, idle is too fast. If the engine
stalls, idle is too slow. Adjust speed
until engine runs without chain movement (idle too fast) or stalling (idle too
slow).
• Turn idle screw (T) clockwise to increase engine speed.
• Turn idle screw (T) counterclockwise
to decrease engine speed.

Fuel stabilizer is an acceptable alternative 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
containers. Run engine at least 5 minutes after adding stabilizer.
Craftsman 40:1,2-cycle
engine oil (air
cooled) is especially blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to your
fuel tank.
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.

YOUR WARRANTY RIGHTS AND
OBLIGATIONS:
The U. S. Environmental Protection Agency and Sears,
Roebuck and Co., U.S.A., are pleased
to explain the emissions control system warranty on your lawn and garden
equipment engine. All new utility and
lawn and garden equipment engines
must be designed, built, and equipped
to meet the stringent anti-smog standards. Sears must warrant the emission control system on your lawn and
garden equipment engine for the periods of time listed below provided there
has been no abuse, neglect, or improper maintenance of your lawn and
garden equipment engine. Your emission control system includes parts
such as the carburetor and the ignition
system. Where a warrantable condition
exits, Sears will repair your lawn and
garden equipment engine at no cost to
you. Expenses covered under warranty include diagnosis, parts and labor.
2O
MANUFACTURER'S
WARRANTY
COVERAGE: If any emissions related
part on your engine (as listed under
Emissions Control Warranty Parts List)
is defective or a defect in the materials
or workmanship
of the engine causes
the failure of such an emission related
part, the part will be repaired or replaced by Sears. 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 instruction 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

shall be warranted for 2 years. Any

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

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
