HANDLE FUEL WITH CAUTION
• Do not smoke while handling fuel or
while operating the saw.
• Eliminate att 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 fuet purposes. Wipe up
atl fuel splits before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting engine.
• Turn the engine off and let saw cooI
in a non-combustible area, not on
dry leaves, straw, paper, etc. Slowly

heaters, electric motors or switches,
furnaces, etc.
GUARD AGAINST KICKBACK
Follow alI safety ruIes to help avoid
kickback and other forces which can
result in serious injury.
_,_\ _,_ Kickback Path
Avoid Obstructions
Clear The
Working Area
_ILWARNING: Avoid kickback
which can resuIt 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 re-
suit 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 ctoses 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.
• 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 stop-
ping puils 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 tet 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 couId
hit white 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 running. Make sure
the bar nuts are securely tightened.
• Begin and continue cutting at futl
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 Putl-ln:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of ptastic or wood.
Never use metal to ho_d the cut open.
MAINTAIN CONTROL
Stand to the left of the saw
Thumb on
h O,s,de",{
Never reverse hand positions
• A good, firm grip on the saw with both
hands will heIp 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 teft thumb
under the front handlebar. Keep your

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 aIIowing 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 Jow-
kickback saw chains reduce the chance
and magnitude of kickback and are rec-
ommended. Your saw has a tow 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 Iightning 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 devices built into
your SaW.

_ll, WARNING: Muffter is very hot
during and after use. Do not touch the
muffIer or allow combustible material
such as dry grass or fuel to do so.
_LWARNING: Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin, tf 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 can 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
Iubrication to the chain and guide bar.
Be sure to fiIt the bar oil tank when you
fill the fueI tank (Capacity = 6.8 ft. oz.).
Lack of oil win 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 oit
is not available, you may use a good
grade SAE 30 oiI until you are aMe 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. Atways fill the bar oil tank when
you fill the fuet tank.
FUELING ENGINE
_WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unteaded gasoline. Before operation,
gasotine must be mixed with a good
quatity synthetic 2-cycIe air-cooIed en-
gine oil. We recommend Craftsman
brand synthetic oil. Mix gasoline and
oit at a ratio of 40:1. A 40:1 ratio is ob-
tained by mixing 3.2 ounces of oil with
1 gailon 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 or boat oil
These oils wiit cause engine damage.
When mixing fuel fottow the instruc-
tions printed on the oil container. Once
oil is added to the gasoline, shake
container momentarily to assure that
the fuet is thoroughly mixed. Always
read and follow the safety rules relat-
ing to fueI before fueling your unit.
IMPORTANT
Experience indicates that alcohol-
blended fueis (called gasohol or using
ethanot 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 cteaner products in the fuel tank
or permanent damage may occur,
See the STORAGE section for additionai
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.
_ 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.
• Move ON/STOP switch to the STOP
position.

CHAINBRAKE
_b'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 any part is worn to tess
than 0.020" (0.5 ram) thick. Repairs on
a chain brake should be made by your
Sears Service Center. Take your unit
to the piace 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).
• Ifthe brake is already activated, it is
disengaged by puiting the front hand
guard back toward the front handle
as far as possible.
• When cutting with the saw, the chain
brake must be disengaged.
Braking function control
CAUTION: The chain brake must be
checked several times daily. The en-
gine must be running when performing
this procedure. This is the onIy
instance when the saw shouid 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 futt throttle by fully depressing
the throttle trigger. Activate the chain
brake by turning your left wrist against
the hand guard without releasing your
grip around the front handle. The chain
shoutd stop immediately.
Inertia activating function control
_kWARNING: When performing
the foitowing procedure, the engine
must be turned off.
Grip the rear handte with your right hand
and the front handle with your teft hand.
Hotd the chain saw approximately 14
inches (35 cm) above a stump or other
wooden surface. Reiease your grip on
the front handle and use the weight of
the saw to let the top 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, and
each time before you start the chain
saw. See CHAIN TENSION in the
MAINTENANCE section.
• Cut wood only. Do not cut metaI, 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 for 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 rite.
• Keep the chain out of dirt and sand.
Even a smaII 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 "feeF of using your saw before
you begin a major sawing operation.
• Squeeze the throttIe 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.
• Altow the chain to cut for you. Exert
onty light downward pressure, tf
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. Ifyou run the saw
at full throttle without a cutting toad,
unnecessary wear can occur to the
chain, bar, and engine. To maxi-
mize operating efficiency, do not
run the engine for longer than 30

TREE FELLING TECHNIQUES
_II, 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 falt, 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. tf
the tree makes contact with any utility
Iine, the utility company should be noti-
fied immediately.
•Carefuily plan your sawing operation
in advance.
• Ctear the work area. You need a ciear
area nil around the tree so you can
have secure footing.
• The chain saw operator shoutd 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 fail in a particular direction include:
• The wind direction and speed.
• The lean of the tree. The tean of a
tree might not be apparent due to un-
even or sloping terrain. Use a piumb
or level to determine the direction of
tree lean.
• Weight and branches on one side.
• Surrounding trees and obstactes.
Look for decay and rot. If the trunk is
rotted, it can snap and fall 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 fail Maintain a dis-
tance of 2 _/2tree lengths from the near-
est person or other objects. Engine
noise can drown out a warning call.
Remove dirt, stones, loose bark, naiis,
staples, and wire from the tree where
cuts are to be made.
Plan a ctear retreat path to the rear
and diagonal to the line of fail
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 wiII tend to fail into
the notch.
NOTE: If the 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 THE
TREE
• Make notch cut by cutting the top of
the notch first. Cut through 1/3of the
diameter of the tree. Next compiete
the notch by cutting the bottom of the
notch. See iiiustration. Once the
notch is cut remove the notch of
wood from the tree.
Final (felting) cut here, 2 inches
(5 cm) above center of notch
i' _.j..
Notch _ _t =
• 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 witt leave enough uncut
wood between the felling cut and the
notch to form a hinge. This hinge wili
help prevent the tree from faliing 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 if necessary
to control the direction of fall. To avoid
11
kickback and chain damage, use wood
or p}astic wedges, but never steel or iron
wedges.
• Be alert to signs that the tree is
ready to fail: cracking sounds, widen-
ing of the feI}ing cut, or movement in
the upper branches.
• As tree starts to fall stop saw, put it
down, and get away quickly on your
ptanned retreat path.
• DO NOT cut down a partially fatten tree
with your saw. Be extremely cautious
with partially fallen trees that may be
poody supported. When a tree doesn't
falI comptetely, set the saw aside and
pul} down the tree with a cable winch,
bIock and tackle, or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired tog size.
dab WARNING: Do not stand on the
tog being cut. Any portion can rott
causing toss of footing and control, Do
not stand downhill of the log being cut.
IMPORTANT POINTS
• Cut on}y one tog at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be f_ung
toward operator.
• Use a sawhorse to cut small logs.
Never allow another person to hold
the Iog white cutting and never hold
the Iog with your teg or foot.
• Do not cut in an area where _ogs,
timbs, and roots are tangled such as
in a blown down area. Drag the togs
into a ctear area before cutting by
putHng out exposed and cIeared togs
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 tose 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 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 _og. When overcutting use
light downward pressure,
6%
Undercutting:
Undercutting involves cutting on the
underside of the log with top of saw
against the _og. When undercutting
use light upward pressure. Hotd saw
firmty and maintain control. The saw
wiI_tend to push back toward you.
A_ILWARNING: 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 ofthe Iog. The compres-
sion side of the tog is where the pres-
sure of the log's weight is
concentrated.
_rst cut On compression side of log
Second cut
First cut on compression side of log
BUCKING WITHOUT A SUPPORT
• Overcut through 1/3of the diameter
of the log.
• Roll the Iog over and finish with a
second overcut.
• Watch for togs with a compression
side to prevent the saw from pinch-
ing. See ittustrations for cutting togs
with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is a_ways on
the compression side of the log.
(Refer to the illustrations below for
your first and second cut)
Second cut

LIMBING AND PRUNING
_IIWARNING: 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. Al-
lowing such contact can resutt in serious
injury.
_iI_WARNING: Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any posi-
tion which can cause you to lose your
balance or control of the saw.
IMPORTANT POINTS
• Work slowly, keeping both hands firmty
gripped on the saw. Maintain secure
footing and balance.
• Watch out for springpotes, SpringpoIes
are smalt 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
clear branches out of the way to avoid
tripping over them.
LIMBING
• Always timb a tree after it is cut
down. OnIy then can limbing be done
safely and properly.
• Leave the larger limbs underneath the
fetted tree to support the tree as you
work.
• Start at the base of the foiled tree and
work toward the top, cutting branches
and limbs. Remove smaII 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 smalI
and freety hanging limbs. Undercutting
could cause limbs to fail and pinch the
SaW.
PRUNING
_I'WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder,
Get a professional to do the job.
• Make your first cut 1/3of the way
through the bottom of the limb.
• 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,

tcounterctockwise); then, loosen
chain by turning the ad usting
wheel 1/4.turn (upward direction).
Retighten bar knob.
9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate
the saw if the chain is loose.
NOTE: The chain is tensioned correctly
when the weight of the chain does not
cause itto sag below the guide bar
twith the chain saw sitting in an upright
position), but the chain still moves freely
around the guide bar.
_WARNING: If the saw is operated
with a loose chain, the chain could jump
off the guide bar and result in serious
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 dull
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.

not moving.
Conditions which indicate the need for
chain sharpening:
• Reduction in size of wood chips, The
size of the wood chip wilt 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 side or at an angle,
• Saw has to be forced through the cut.
Tool8 required:
• 5/32 inch (4 mm) diameter round file
and file holder
• Flat file
• Depth gauge tool
