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 sawonly 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 pads 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-
sodes 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 pads, 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.

• 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 diginto 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 cha,n 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 di-
rection 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 bot-
tom of the guide bar and the saw
chain is suddenly stopped. This
sudden stoppingpulls the saw for-
ward and away from the operator
and could easily cause the opera-
tor 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
surpdse which contdbutes to acci-
dents.
any object at the tip of the guide bar.
_ Never let the moving chain contact
Keep working area free from obstruc-
tions such as other trees, branches,
rocks, fences, etump6, etc. Eliminate
or avoid any obstruction that your saw
chain could hit while cutting.
• When cuffing a branch, do not let the
guide bar contact another branch or
other objects around it
• Keep saw chain sharp and propedy
tensioned. A loose or dull chain can
increase the chance of kickb_lck. Fol-
low manufacturer's chain sharpening
and maintenance instructions. Check
tension at regular intervals, but never
with engine running. Make su[e chain
brake nuts are securely tightened.
• Begin and continue cuttin_ at ful!
speed. If the chain is moving at a
slower speed, there is greate_ chance
of kickback occurring.
• Use extreme caution when repntering
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 pinph 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 Ftaterial
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 cpt open.

KICKBACK SAFETY FEATURES
WARNING: 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 serious 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-lina" 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.

CHAIN BRAKE
• Chain Brake: designed to stop the
chain in the event of kickback.
_,WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
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 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
whk_h could result inserious 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 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.
• lip 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.

_lbWARNING: 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.
BEFORE STARTING ENGINE
_, WARNING: Be sure to read the
fuel handling information in the safety
rules section of this manual 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 ft. oz.),
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
_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 2-cycle air-cooled engine oil.
We recommend Craftsman brand oil.
Mix gasoline and oil at a ratio of 40:1.
A 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline. Included with this saw is a
3.2 ounce container of Craftsman
brand oil. Pour the entire contents of
this container 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 pdnted 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. To avoid engine
problems, the fuel system should be
emptied before storage for 30 days or
longer. Drain the gas tank, stad the en-
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 clean-
er products in the fuel tank or perma-
nent damage may occur.
See the STORAGE section for addition-
al 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 disen-
gaged before cutting with the saw.
A
,Ira 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 sedous bums.

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
40&WARNING: Check for broken or
dead branches which can fall while
cutting causing serious injury. Do not
cut qear buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be a_01eto see well, nor during bad
weather such as rain, snow, or strong
winds, etc. If a tree makes contact with
any utility line, the utility company
shoqld 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.
• Th e 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.
• S_urrounding 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.
• Reprove dirt, stones, loose bark,
nails, staples, and wire from the tree
whpre cuts are to be made.

FELUNG 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.
Felling cut here
First cut =.. /
/,
Notch _ _ ._.. ""_-"lr
• 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
controlfall
Opening of
felling cut
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.
• 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.
cu'n'ING A FALLEN TREE
(BUCKING)
Bucking is the 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.
BUCKING TECHNIQUES
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
Tum saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins onthe top side of
the logwith the bottom ofthe saw
against the log.When overcutting use
lightdownward pressure.

_tting Und_rc_in_g
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 tum 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.

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 sedous injury.
Firstcut 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 pinch-
ing. See illustration 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 iUustrations 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.
Using a log for support
I stCut
_WARNING: 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.
Spdngpoles are small size limbs
which can whip toward you, or pull
you off balance. Use extreme cau-
tion when cutting small size limbs.
• Be alert for spdngback 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 tdpplng over them.
LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.

• Keep the tree between you and the
chain.
• Remove larger branches with the
cutting techniques described in
BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut small
and freely hanging limbs. Undercut-
ting could cause limbs to fall and
pinch the saw.
PRUNING
• Next make the second cut an over-
cut all the way through the limb.
• Finish the pruning operation by using
an overcut so that the stump of the
limb protrudes 1 to 2 inches from the
trunk of the tree.
eC_d cut
_WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoul-
der. Get a professional to do the job.
• Make your first cut 1/3 of the way
through the bottom of the limb. This
cut will make the limb sag so that it
falls easily on the second cut.

CHECKGUIDEBAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
After each use, ensure ON/STOP
switch is in the STOP position, then
clean all sawdust from the guide bar
and sprocket hole.
To maintain guide bar:
• Move ON/STOP switch to STOP.
• Loosen and remove chain brake
nuts and chain brake. Remove bar
and chain from saw.
• Clean the oil holes and bar groove

CLEAN AIR FILTER
A dirty air filter decreases the life and
performance of the engine and in-
creases fuel consumption and harmful
emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of op-
eration, whichever comes first. Clean
more frequently in dusty conditions. A
used air filter can never be completely
cleaned. It is advisable to replace your
air filter with a new one after every 50
hours of operation, or annually, which-
ever comes first. To clean filter:
1. Loosen 3 screws on cylinder
cover.
2. Remove cylinder cover.
3. Remove air filter.
4. Clean the air tilter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstal-
ling.
