Wear protective gear. Always use
steel4oed safety footwear with non-slip soles; snug4itting clothing; heavy-duty,
non-slip gloves; eye protection such as non4ogging, vented goggles or
face screen; an approved safety hard
hat; and sound barriers (ear plugs or mufflers) to protect your hearing. Reg-
ular 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 ani- mals at least 30 feet (10 meters) away from the work area when start-
ing 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.
2
OPERATE YOUR SAW SAFELY
Do not operate with one hand. Seri- ous injury to the operator, helpers, or bystanders may result from one-
handed operation, A chain saw is in-
tended for two-handed use.
Operate the chain saw only in a well- ventilated 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, es- pecially 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 project-
ing 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 im- mediately if they become damaged, broken, or are otherwise removed.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
Have all chain saw service per-
formed by a qualified service dealer
except the items listed in the MAINTE- NANCE 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 compo- nents or the removal of safety devices
may cause damage to the unit and possible injury to the operator or by-
standers. Use only Craftsman acces- sories and replacement parts as rec-
ommended. 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 fur- ther 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 con-
tainer 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 va-
pors 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.
%_S Avoid Obstructions
Clear The Working Area
4_WARNING: Avoid kickback which can result in serious injury. Kickback
is the backward, upward or sudden for-
ward 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 re-
versal 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.
Pull4n 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 stop- ping 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 kick-
back, you can reduce the element of surprise which contributes to acci-
dents,
Never let the moving chain contact
any object at the tip of the guide bar.
Keep working area free from obstruc- tions 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. Fol- low 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.

KICKBACK SAFETY FEATURES
_IbWARNING: The following features are included on your saw to help reduce
hazard of kickback; however, such fea-
tures will not totally eliminate this danger.
Do not rely only on safety devices. Fol- low all safety rules to help avoid kick- back and other forces which can result
in senous injury,
Front Hand Guard: designed to reduce
the chance ofyour left hand contact-
ing the chain if your hand slips off the
front handlebar.
Position of front and rear handlebars: designed with distance between han-
dles 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 resis- tance in controlling the pivot of the
saw back toward the operator if kick- back occurs.
Reduced-Kickback Guide Bar: de- signed with a small radius tip which
reduces the size of the kickback dan- ger 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.
Low*Kickback Chain: has met kick- back performance requirements when
tested on a representative sample of
chain saws below 3.8 cubic inch dis-
placement specified in ANSI B175.1.
Low-Kickback Chain
CHAIN BRAKE
Chain Brake: designed to stop the chain in the event of kickback.
dubWARNING: WE DO NOT REP-
RESENTAND YOU SHOULD NOTAS- SUME THAT THE CHAIN BRAKE WILL PROTECT YOU INTHE EVENT OF A
KICKBACK. Kickback is a lightning fast action which throws the bar and rotat-
ing chain back and up toward the op- erator. Kickback can be caused by al-
lowing 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 UPONANY OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE THE SAW PROPERLYAND CAREFULLY TO AVOID
KICKBACK. Reduced-kickback guide bars and low-kickback saw chains re-
duce 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 au-
thorized 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 vibra- tions 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 swell-
ing. Prolonged use in cold weather has
been linked to blood vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool
and seek medical attention. An anti-vi-
bration system does not guarantee the avoidance of these problems. Users who operate power tools on a continual and regular basis must closely monitor their physical condition and the condition
of this tool. CHAIN BRAKE: If this saw is to be
used for commercial logging, a chain
brake is required and shall net be re- moved or otherwise disabled to comply
with Federal OSHA Regulations for Commercial Logging.
SPARK ARRESTING SCREEN: Your saw isequipped with a temperature lim-
iting muffler and spark arresting screen
which meets the requirements of Califor-
nia Codes 4442 and 4443. All U.S. for- est land and the states of California, Ida-
ho, Maine, Minnesota, New Jersey, Oregon, and Washington require by law
that many internal combustion engines
be equipped with a spark arresting screen. If you operate a chain saw in a
state or locale where such regulations exist, you are legally responsible for
maintaining the operating condition of
these parts. Failure to do so is a viola- tion of the law. Refer to Customer Re-
sponsibilities chart in the MAINTENANCE section.
STANDARDS: This chain saw is listed by Underwriters Laboratories, Inc. in ac-
cordance with American National Stan- dards for Gasoline-Powered Chain Saws Safety Requirements (ANSI B175.1-2000).

BEFORE STARTING ENGINE
z*L
_ILWARNING: Be sure to read the fuel handling information in the safety
rules section of this manual before you
begin. If you de net understand the fuel handling information de not at-
tempt to fuel your unit. Seek help from someone that does understand the in- formation or call the customer assis-
tance help line at 1-800-235-5878. GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication. The chain oiler provides continuous
lubrication to the chain and guide bar.
Be sure to fill the bar oil tank when you fill the fuel tank (Capacity = 6.8 fi. ez.).
Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheat-
ing shown by smoke coming from the chain and/or discoloration of the bar.
For maximum guide bar and chain life, we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oil
is not available, you may use a good grade SAE 30 oil until you are able to
obtain Craftsman brand. The oil output
is automatically metered during opera- tion. Your saw will use approximately one tank of bar oil for every tank of fuel
mix. Always fill the bar oil tank when you fill the fuel tank.
FUELING ENGINE
II),WARNING: Remove fuel cap slowly when refueling. This engine is certified to operate on un-
leaded gasoline. Before operation, gaso-
line must be mixed with a good quality synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand sym thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix-
ing 3.2 ounces of oil with 1 gallon of unleaded gasoline. Included with this
saw is a 3.2 ounce container of oil.
Pour the entire contents of this con- tainer into 1 gallon of gasoline to
achieve the proper fuel mixture.
DO NOT USE automotive oil or boat oil. These oils will cause engine damage.
When mixing fuel follow the instruc- tions printed on the oil container.
Once oil is added to the gasoline, shake container momentarily to assure
that the fuel is thoroughly mixed. Al- ways read and follow the safety rules
relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol blended fuels (called gasohol or using
ethanol or methanol) can attract mois- ture which leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage. Toavoid engine
problems, the fuel system should be
emptied before storage for 30 days or
longer. Drain the gas tank, start the em
gine 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 occun
See the STORAGE section for additional
information.
CHAIN BRAKE
Ensure chain brake is disengaged by
pulling the front hand guard back to- ward the front handle as far as pos-
sible. The chain brake must be disem
gaged before cutting with the saw.
zl, _____.__
8_b,WARNING: The chain must not
move when the engine runs at idle
speed. If the chain moves at idle
speed, refer to CARBURETOR ADJUST-
MENT within this manual. Avoid con- tact with the muffler, A hot muffler can
cause serious burns.
STOPPING YOUR ENGINE

TROUBLESHOOTING TABLE or call
1-800-235-5878.
CHAIN BRAKE
z_
iIIWARNING: If the brake band is worn too thin it may break when the
chain brake is triggered. With a broken brake band, the chain brake will not stop
the chain. The chain brake must be re-
placed if any part is worn to less than
0.020 inch (0.5 mm) thick. Repairs on a chain brake should be made by your
Sears Service Center. Take your unit to
the place of purchase or to the nearest
Sears Service Center.
This saw is equipped with a chain brake. The brake is designed to stop
the chain if kickback occurs.
The inertia-activated chain brake is activated if the front hand guard is
pushed forward, either manually (by hand) or automatically (by sudden
movement).
If the brake is already activated, it is disengaged by pulling the front hand guard back toward the front handle
as far as possible.
When cutting with the saw, the chain brake must be disengaged.

CAUTION: The chain brake must be checked several times daily. The engine
must be running when performing this procedure. This is the only instance
when the saw should be placed on the
ground with the engine running. Place the saw on firm ground. Grip the
rear handle with your right hand and the
front handle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turn-
ing your left wrist against the hand guard

Inertia activating function control
_WARNING: When performing the following procedure, the engine must
be turned off.
Grip the rear handle with your right hand and the front handle with your left hand.
Hold the chain saw approximately 14" (35 cm) above a stump or other wood- en surface. Release your grip on the
front handle and let the tip of the guide
bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate. OPERATING TIPS
Check chain tension before first use
and after 1 minute of operation. See CHAIN TENSION in the MAINTENANCE
section.
Cut wood only. De not cut metal,
plastics, masonry, non-weed 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 us-
ing the following steps. This will help
you get the "feel" of using your saw
before you begin a major sawing op- eration.
Squeeze the throttle trigger and al- low 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.
TREE FELLING TECHNIQUES
_WARNING: 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, If the tree does make con-
tact with any utility line, the utility com-
pany 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 di- rection 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.
Plan a clear retreat path
;t.... U--""""_- Direction of fali

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.
NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots, keep saw chain from contacting ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
Make notch cut by cutting the 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, re- move the wedge of wood from tree.

Se l \
After removing the wood from the
notch, make the felling cut on the op- posite 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

Closinc of notch
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, widen-
ing 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.
DQ 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 leg size. _!I_WARNING: Do net stand on the
leg 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.
De net 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
Z_ d_II_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, Re- start saw and carefully reenter the cut,
Do not use a metal wedge. Do not at-
tempt 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.
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.
zl, _____.__
_IbWARNING: Never turn saw up- side down to undercut. The saw can-
not be controlled in this position.
Always make your first cut on the com-
pression side of the log. The compres-
sion side of the log is where the pres- sure of the log's weight is
concentrated.

BUCKING WITHOUT A SUPPORT
Overcut through I/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 pinch-
ing. See illustrations above for cut-
ting 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. (Re- fer 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.
LIMBING AND PRUNING
_WARNING: Be alert for and guard
against kickback. Do not allow the mov- ing 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.
_IbWARNING: Never climb into a tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any po- sition 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 pres-
sure, 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.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cov- er items that have been subjected to operator abuse or negligence. To re-
ceive full value from the warranty, the operator must maintain unit as instruct-
ed 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
Contact Sears Service Center for re-
placement of damaged or worn parts. NOTE: It is normal for a small amount
of oil to appear under the saw after en- gine stops. Do not confuse this with a
leaking oil tank.
ON/STOP Switch - Ensure ON/STOP switch functions properly by moving
the switch to the STOP position.
Make sure engine stops; then restart engine and continue.
Fuel Tank - Do not use saw if fuel
tank shows signs of damage or
leaks.
Oil Tank - Do not use saw if oil tank shows signs of damage or leaks.

CHECK CHAIN TENSION _IlbWARNING: 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 es-
pecially 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.

2. Loosen chain brake nuts until they are finger tight against the chain brake.
3. Turn adjusting screw clockwise un- til chain solidly contacts bottom of guide bar rail.
__ Adjusting Screw
4. Using bar tool, roll chain around guide bar to ensure all links are in bar groove.
5. Lift up tip of guide bar to check for sag. Release tip of guide bar, then turn adjusting screw until sag does
not exist.
6. While lifting tip of guide bar, tighten chain brake nuts securely with the
bar tool.
7. Use the screwdriver end of the bar tool to move chain around guide
bar.
8. If chain does not rotate, it is too tight. Slightly loosen chain brake
nuts and loosen chain by turning the adjusting screw counterclock- wise. Retighten chain brake nuts.
9. If chain is too loose, it will sag be- low the guide bar. DO NOT operate
the saw if the chain is loose.
41bWARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in se-
rious injury.
