OPERATEYOURSAWSAFELY
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 themrnovai 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 pads, 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.
•Tum 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, fumaces, etc.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid kickback and other forces which can
result in sedous injury.
3
WARNING: Avoid kickback which
can result in sedous 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 diginto the object, which stops the chain for an instant. The
result is a lightning fast, reverse reaction wh=ch 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 oar ano
the saw chain is suddenly stopped. This sudden stopping of the chain
results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite 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 end away.from the operator and could easdy cause the opera- tor to lose control of the saw.
REDUCE THE CHANCE OF KICKBACK
Recognize that kickback can .ha_N_=n.. W'dh a basic understanding of kick-
back, you can reduce the element of surpdse 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 cuffing.no t
When cutting a branch, do guide bar contact another branch or other objects around it.
Keep saw chain sharp and propedy

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 et a slower speed, there is greater chance of kickback occurring.

Use the specified Reduced-1<3ckback 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.

KICKBACK SAFETY FEATURES
WARNING: The following features
ere 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 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 hen-
dlos 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 con_'olling the pivot of the saw back toward the operator if kick-
back occurs
Reduced-I'Qckback 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 sedousness of kickbacks when tested in accordance
with ANSI B175.1.

_ WARNING: WEDONOTREP-
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 which could result in sedous 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-
dune 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 sases 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 beck toward the operator.
Either of these mactio_ 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.

_ WARNING: Muffler is very hot
dudng 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.
FUEUNG 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 all 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 momentadly to assure
that the fuel is thoroughly mixed. Al- ways read and follow the safety roles
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 damagethe 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. 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 _
4_lbWARNING: 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. STOPPING YOUR ENGINE

flooded engine) The engine may be I]ooded if it has not
started after 10 pulls. Flooded engines can be cleared of ex-
cess fuel by following the warm engine starting procedure listed above. Insure the ON/STOP switch is in the ON position.
Starting could require many pulls de- pending on how badly unit is flooded.
If engine still fails to start, refer to the
TROUBLESHOOTING TABLE or call
1-800-235-5878. CHAIN BRAKE
_. 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 re-
placed if any part is worn to less than 1/32" 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 Ser-
vice 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.
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 only
instance when the saw should be placed on the ground with the engine
running.
Place the sew on firm ground. Grip the
rear handle with your dght hand and the front handle with your left hand.

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 wooden
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 I minute of operation. See CHAIN TENSION in the MAINTENANCE
section.
Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc.
Stop the saw if the chain strikes a foreign object. Inspect the saw and
repair parts as necessary.
Keep the chain out of dirt and sand. Even a small amount of dirt will
quickly dull a chain and increase the possibility of kickback.
Practice cutting a few small legs 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 leg.
Keep the englne at full speed the
entire tim9 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 FELUNG TECHNIQUES
_lL 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 a tree makes contact with any utility line, the utility company
should be notified immediately.
Carefully plan your sawing operation in advance.
Clear the work area. You need a clear area all around the tree so you
can have secure footing.
The chain saw operator should keep on the uphill side of the terrain as the
tree is likely to roll or slide downhill after it is felled.
Study the natural conditions that can cause the tree to fall in a particular
direction. These conditions include:
The wind direction and speed.
The lean of the tree. The lean of a
tree might not be apparent due to uneven or sloping terrain. Use a
plumb or level to determine the 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 waming call.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree
where cuts are to be made.
Plan a clear retreat path
Oi onof l

FELUNG LARGE TREES (6 inches in diameter or larger)
The notch method is used to fell large
bees. A notch is cut on the side of the tree in the desired direction of fail. 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.
I Felling cut here
Firstcut"_ _ "_ =,,,_..t!...:"_|
Notch -....._ _ ._..:r
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 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
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, usa wood or plastic wedges,
but never steel or iron wedges.
Be alert to signs that the tree is
ready to fail: crocking 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 poody 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 log size.
A0kWARNING: 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 dear area before cuffing 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 sew, ddve 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 Sawwhen it is
pinched or hung in a log.
Use a wedge to remove pinched saw
Tum saw OFF and use a plasticor wooden wedge to force cut open,
Overcutting begins on the top side of
the log with the bottom of the saw against the log. When overcutting use
light downward pressure.
11
_uttlng U_
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.
_IkWARNING: Never tum saw up-
side down to undercut. The sew 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,

UMBING 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.
First cut on compression side of log
BUCKING WITHOUT A SUPPORT
Overcut through 1/3 of the diameter
of the log.
Roll the log over and finish with a second overcut.
Watch for logswith 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 isalways on
the compression side of the log. (Re- fer to the illustrations below for your first and second cut).
Your first Cutshould extend 1/3 of the diameter ofthe log.
Finish with your second cut.

WARNING: Never climb intoa
tree to limbor prune. Do not stand on
ladders, platforms,a log, orin any po- sitionwhich can cause you to lose your balance or controlofthe sew.
IMPORTANT POINTS
Watch out for springpoles.
Spdngpoles are small size limbs whichcan whiptoward you, or pull
you off balance. Use extreme cau- tion when cuttingsmall size limbs.
Be alert for spdngback from any branches that are bent or under
pressure.Avoid being struck by the branch orthe sew when the tension
in the wood fibers"is released.
Frequently clear branchesout of the way to avoid tdppingover them.
MMBING
Limb a tree only after itis cutdown.
Leave the larger limbsunderneath
the felled tree to supportthe tree as you work.
Start at the base ofthe felled tree
and work toward the top, cutting branches and limbs. Remove small
limbs with one cut.
12
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.
_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.

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.

WARNING: If the saw is operated
with a loose chain, the chain could jump off the guide bar and result in se-
rious injury. CHECK CHAIN SHARPNESS A sharp chain makes wood chips. A dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING in the SERVICE AND ADJUST- MENTS section.
