OPERATE YOUR SAW SAFELY
• Do not operate a chain saw with one
hand. Serious injury to the operator,
helpers, bystanders or any combina
tion of these persons may result from
one-handed 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 at
the end of the cut. Applying pressure
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 com pletely and securely as
sembled. Always replace bar, chain,
hand guard, or chain brake immedi
ately if it becomes damaged, broken
or is otherwise removed.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
k WARNING; Disconnect the
spark plug before performing mainte
nance except carburetor adjustments.
• Have ail chain saw service performed
by a qualified service dealer with the
exception of 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 ADJUSTMENT
• Keep the handies dry, dean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
lightened.
• Nonconforming replacement compo
nente 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 dean for better
and safer performance.
• Foilow instructions for lubricating and
changing accessories,
• Check for damaged parts. Before fijrther 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 operator's manual,
• When not in use, chain saws should
be stored in a dry, high or boked-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 a!i sources of sparks or
flame in the 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
ail fuel spiils before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting engine.
• 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 refue! unit.
• Empty the fijei tank before storing or
transporting the unit Use up fuel ieft in

sparks or open fiâmes from water
heaters, eiectric motors or switches,
furnaces, etc.
GUARD AGAÎNST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
Page 4
aWARNING: 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 doses in and pinches
the saw chain in the cut. Contacting a
foreign object in the wood can also re
sult 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 sud
den 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.
• Puli-ln 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 hap
pen. With a basic understanding of
kickback, you can reduce the ele
ment of surprise which contributes to
accidents,
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keep the working area free from ob
structions such as other trees,
branches, rocks, fences, stumps,
etc. Eliminate or avoid any
obstruction that your saw chain could
hit while you are cutting.
• When cutting a branch, do not let the
guide bar contact branch or other ob
jects 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 the engine mnning. Make sure
the bar 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 re-enter
ing a previous 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
fail into chain.
• Use the Reduced-Kickback Guide
Bar and Low-Kickback Chain speci
fied for your saw.
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 the saw as the 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.
MAINTAIN CONTROL
Stand to the left of the saw
Thumb on
underside
of handleb:
Never reverse hand positions
A good, firm grip on the saw with both
hands will help you maintain control.
Don't let go. Grip the rear handle with
your right hand whether you are right
or left handed. Wrap the fingers of
your left hand over and around the
front handlebar, and your left thumb
under the front handlebar. Keep your
left arm straight with the elbow locked.
Page 5
• Position your left hand on the front
handiebar so it is in a straight !ine
with your right hand on the rear
handle when m aking bucking cuts.
Never reverse right and left hand
positions for any type of cutting.
• Stand with your weight evenly bal
anced on both feet.
• Do not overreach. You could be
drawn or thrown off balance and lose
control of the saw.
• Do not cut above shoulder height. It
is difficult to maintain control of saw
above shoulder height,
KiCKBACK SAFETY FEATURES
^ WARNING; The following fea
tures are included on your saw to help
reduce the 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 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
danger zone on the bar tip. This type
of bar has been demonstrated to sig
nificantly reduce the number and se
riousness of kickbacks when tested
in accordance with ANSI B175.1.

CHAIN BRAKE
• Chain Brake, designed to stop the
chain in the event of kickback.
^WARNING: we do no t rep
resen t AND YOU SHOULD NOT AS
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A KICK
BACK. Kickback is a lightning fast action
which throws the bar and rotating chain
back and up toward the operator. Kick
back 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 AVOfD KICKBACK.
Reduced-kickback guide bars and iowkickback saw chains reduce the chance
and magnitude of kickback and are rec
ommended. Your saw has a low kick
back chain and bar as original equip
ment. Repairs on a chain brake should
be made by an authorized Sears Ser
vice Center, Take your unit to the place
of purchase if purchased from a servic
ing dealer, or to your nearest Sears Ser
vice 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
couid result in serious injury. Do not
reiy exclusively upon devices built into
your saw.

BEFORE STARTING ENGINE
^ WARNING; Muffler is very hot
during and after use. Do not touch the
muffler or allow combustible material
such as dry grass or fuel to do so.
A WARNING: Be sure to read the
fuel handling information in the safety
rules section of this m anual before you
begin. If you do not understand the
fuel handling information do 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 fl. oz.).
Lack of oil wiil 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 fuei tank.
FUELING ENGINE
A WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality synthetic 2-cycle air-cooled en
gine oil. We recommend Craftsman
brand synthetic oil. Mix gasoline and
oil at a ratio of 40:1. A 40:1 ratio is ob
tained by m ixing 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 ftiis con
tainer into 1 gallon of gasoline to
achieve the proper fuel mixture.
DO NOT USE automotive or boat oil.
These oils wiil cause engine damage.
When m ixing fuel follow the instruc
tions printed on the oil container. Once
oil is added to the gasoline, shake
container momentarily to assure that
the fuei is thoroughly mixed. Always
read and follow the safety rules relat
ing to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcoholblended 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. To avoid engine
problems, the fuel system should be
emptied before storage for 30 days or
longer. Drain the gas tank, start the en
gine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel
next season. Never use engine or car
buretor cleaner products in the fuel tank
or permanent damage may occur.
See the STORAGE section for additional
information
CHAIN BRAKE
Ensure chain brake is disengaged by
pulling the front hand guard back toward
the front handle as far as possible. The
chain brake must be disengaged before
cutting with the saw.
A 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 contact
with the muffler. A hot muffler can
cause serious burns.
STOPPING YOUR ENGINE
• Release the throttle trigger.

^ WARNING: 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 replaced if arty part is worn to less
than 0,020" (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 near
est 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),

OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation, and
each time before you start the chain
saw. See CHAIN TENSION in the
MAiNTENANCE section.
• Cut wood only. Do not cut metal, plas
tics, masonry, non-wood building ma
terials, etc.
• Stop the saw if the chain strikes a
foreign object, inspect the saw and
repair or replace parts as necessary.
If the chain jumps off the guide bar,
inspect the chain tor damaged drive
links before reinstalling. Burrs on
drive links, which prevent them from
entering the groove of the guide bar,
can be removed with a flat file.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will dull a
chain, increase the possibility of kick
back, and require chain sharpening or
replacement.
• Practice cutting a few small logs us
ing the following techniques to get
the '‘fee!” 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 cutfor you. Exert
only light downward pressure. If
you force the cut, damage to the
bar, chain, or engine can result.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. Ifyourunthesaw
at fuli throttle without a cutting load,
unnecessary wear can occur to the
chain, bar, and engine. To maxi
mize operating efficiency, do not
run the engine for longer than 30
seconds at a time at full throttle.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop the engine before setting the
saw down after cutting.

TREE FELLING TECHNIQUES
^ WARNING; Check for broken or
dead branches which can fall while cut
ting 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 aie to
see well, nor during bad weather such
as rain, snow, or strong winds, etc. If
the tree makes contact with any utility
line, the utility company should be noti
fied 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 di
rection.
Natural conditions that can cause a tree
to fall in a particular direction include;
• The wind direction and speed.
• The lean of the tree. The lean of a
tree might not be apparent due to un
even 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 fail toward the
operator. Check for broken or dead
branches which can fall on you while
cutting. Make sure there is enough
room for the tree to fall. Maintain a dis
tance of 2-1/2 tree lengths from the near
est 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 to the rear
and diagonal to the line of fall.
FELLING LARGE TREES
(6 inches (15 cm) 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 into
the notch.
NOTE: If the tree has large buttress
roots, remove them before making the
notch. It using saw to remove buttress
roots, keep saw chain from contacting
ground to prevent dulling of the chain.
NOTCH CUT AND FELLING THE
TREE
• Make notch cut by cutting the top of
the notch first. Cut through i/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom of the
notch. See illustration. Once the
notch is cut remove the notch of
wood from the tree.
Final (felling) cut here, 2 inches
(5 cm) above center of notch.
■ 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 (5
cm) 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 fail
NOTE: Before telling cut is complete,
use wedges to open the cut if necessary
to control the direction of fall. To avoid
11
Page 12
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.
• DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious
with partialy fallen trees that may be
poorly supported. When a tree doesn’t
fail 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.
A 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 sm all 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 togs,
limbs, and roots are tangled such as
in a blown down area. Drag the logs
into a clear area before cutting by
pulling out exposed and cleared logs
first.
TYPES OF CUTTING USED FOR
BUCKING
A 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 the saw and carefully reenter
the cut. To avoid kickback and chain
damage, do not use a metal wedge.
Do not attempt to restart your saw
when it is pinched or hung in a log.
Use 3 wedge to remove pinched saw
Turn saw OFF and use a piastto or
wooden wedge to force cut open.
Overcutting begins on the top side of
the log with the bottom of the saw
against the tog. When overcutting use
light downward pressure.
Undercutting
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.
^WARNING: 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.
First out on compression side of log
First out on compression side of log
BUCKING WITHOUT A SUPPORT
• Overcut through 1/3 of the diameter
of the tog.
• 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 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)
12
Page 13
• Your first cut should extend 1/3 of the
diameter of the log.
• Finish with your second cut.
Using a tog for support
Using a support stand
LIMBING AND PRUNING
A WARNING: Be alert for and
guard against kickback. Do not allow the
moving chain to contact any other
branches or objecte at the nose of the
guide bar when limbing or pruning. Al
lowing such contact can result in serious
injury.
A WARNING: Never climb into a
tree to limb or prune. Do not stand on
ladders, piatforms, a log, or in any posi
tion which can cause you to lose your
baiance or control of the saw.
IMPORTANT POINTS
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure
footing and balance.
• Watch out for springpoies. Springpoles
are small size limbs which can catch
the saw chain and whip toward you or
pull you off balance. Use extreme cau
tion when cutting small size limbs or
slender material.
• Be alert for springback. Watch out for
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.
• Keep a clear work area. Frequently
dear branches out of the way to avoid
tripping over them.
LIMBING
• Always limb a tree after it is out
down. Only then can limbing be done
safely and properly.
• Leave the larger limbs underneath the
felled tree to support the tree as you
wortt.
• Start at the base of the felled tree and
wort toward the top, cutting branches
and limbs. Remove small limbs with
one cut.
• Keep the tree between you and the
chain. Cut from the side of the tree op
posite the branch you are cutting,
• Remove larger, supporting branches
with the cutting techniques described
in BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut smalt
and freely hanging lim bs. Undercutting
couid cause limbs to fall and pinch the
saw.
PRUNING
A WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder.
Gel a professionat to do the job.
• Make your first cut 1/3 of the way
through the bottom of the lim b.
• Next make a 2nd cut all the way
through the limb. Then cut a third
overcut leaving a 1 to 2 inch (2,5 to 5
cm) collar from the truck of the tree.

injury to the operator and/or damage the
chain making it unusable. If the chain
jumps off the guide bar, inspect each
drive link for damage. Damaged chain
must be repaired or replaced,
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A duil
chain makes a sawdust powder and
cuts slowly. See CHAIN SHARPENING.
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,

CHAIN SHARPENING
A WARNING: Improper chain
sharpening techniques and/or depth
gauge maintenance will increase the
chance of kickback which can result in
serious injury.
A WARNING: Wear protective
gloves when handling chain. The chain
is sharp and can cut you even when it is
not moving.
Conditions which indicate the need for
chain sharpening:
• Reduction in size of wood chips. The
size of the wood chip will decrease
as the chain gets duller until it be
comes more like a powder than a
chip. Note that dead or rotted wood
will not produce a good chip.
• Saw cuts to one aide or at an angle.
• Saw has to be forced through the cut.
Tools required:
• 5/32 inch (4 mm) diameter round file
and file holder
• Flat file
• Depth gauge tool
TO SHARPEN CHAIN:
1.
Move ON/STOP switch to the STOP
