• Wear protective gear. Always use
steel-toed safety footwear with non-slip
soles; snug-fitting clothing; heavy-duty,
2
non-slip gloves; eye protection such
as non-fogging, vented goggles or
face screen; an approved safety hard
hat; and sound barriers (ear plugs or
mufflers) to protect your hearing. Regular users should have hearing
checked regularly as chain saw noise
can damage hearing.
Secure hair above shoulder length. Do
not wear loose clothing or jewelry; they
can get caught in moving parts.
Keep all parts of your body away
from the chain when the engine is
running.
Keep children, bystanders, and animals at least 30 feet (10 meters)
away from the work area when starting and using the saw.
Do not handle or operate a chain saw
when you are fatigued, ill, or upset, or
if you have taken alcohol, drugs, or
medication. You must be in good
physical condition and mentally alert. If
you have any condition that might be
aggravated by strenuous work, check
with doctor before operating.
Do not start cutting until you have a
clear work area, secure footing, and
especially if you are felling a tree, a
retreat path.
OPERATE YOUR SAW SAFELY
• Do not operate with one hand. Serious injury to the operator, helpers, or
bystanders may result from onehanded operation. A chain saw is intended for two-handed use.
• Operate the chain saw only in a wellventilated outdoor area.
• Do not operate saw from a ladder or
in a tree.
• Make sure the chain will not make
contact with any object while starting
the engine. Never try to start the saw
when the guide bar is in a cut.
• Do not put pressure on the saw, especially at the end of the cut. Doing
so can cause you to lose control
when the cut is completed.
• Stop engine before setting saw down.
• Hand carry saw only when engine is
stopped. Carry with muffler away
from body; guide bar & chain projecting behind you; guide bar preferably
covered with a scabbard.
• Do not operate a chain saw that is
damaged, improperly adjusted, or not
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
.t..- _
- ]:
Avoid Obstructions
Clear The Working
Area
A
411 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
RESENT AND YOU SHOULD NOT AS,_
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 ANS! B175.1.

• Low-Kickback Chain: has met kickback performance requirements when
tested on a representative sample of
chain saws below 3.8 cubic inch displacement specified in ANS! B175.1.
SUME THAT THE CHAIN BRAKE WiLL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast
action which throws the bar and rotating 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 orto
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.

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 the chain, bar and engine. It is
recommended
that the engine
not be operated for longer than
30 seconds at full throttle.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop engine before setting saw down.
TREE FELLING
_& WARNING:
dead branches
TECHNIQUES
Check for broken or
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. If the tree does make contact with any utility line, the utility company should be notified immediately.
• 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 of the 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.

NOTCH
CUTAND FELLING TREE
• Make notch cut by cutting tile top of
the notch first. Cut through 1/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut, remove the wedge of wood from tree.

e
• 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.
Hinge holds tree on
stump and helps
control fall

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 tile term used for cutting a
fallen tree to the desired log size.
_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.
TYPES OF CUTTING USED FOR
BUCKING
,_
WARNING:
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.
11
1st Cut
_Overcuttingz;G_I_
_;_/
_-_-_" _
Undercutti_',_s
Undercutting involves cutting on the
underside of the log with top of saw
against the log. When undercutting
use light upward pressure. Hold saw
firmly and maintain control. The saw
will tend to push back toward you.
Using a support stand
/
WARNING:
Never turn saw upside down to undercut. The saw cannot be controlled in this position.
Always make your first cut on the compression side of the log. The compression side of the log is where the pressure of the log's weight is
concentrated.

WARNING:
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.
#
First cut on compression side of log
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 illustration 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 illustration 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.

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.

the saw if the chain is loose.
A
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.

YOUR
WARRANTY
RIGHTS AND OBLIGATIONS: The U.S. Environmental
Protection Agency/California Air Resources Board and Sears, Roebuck and
Co., U.S.A., are pleased to explain the
emissions control system warranty on
your year 2000-2003 small off-road engine. In California, all new small off-road
engines must be designed, built, and
equipped to meet the State's stringent
anti-smog standards. Sears must warrant the emission control system on your
small off-road engine for the periods of
time listed below provided there has
been no abuse, neglect, or improper
maintenance of your small off-road engine engine. Your emission control system includes parts such as the carburetor and the ignition system. Where a
warrantable condition exists, Sears will
repair your small off-road engine engine
at no cost to you. Expenses covered under warranty include diagnosis, parts
and labor. 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
small off-road engine 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 small off-road 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 small
off-road engine engine owner, you
should be aware that Sears may deny
you warranty coverage if your small offroad engine 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 small off-road engine to
a Sears authorized repair center as
soon as a problem exists. Warranty re-
pairs 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 small offroad 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 Service
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 part which is
not 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 Service 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
