&IWARNING: Always disconnect spark plug wire when making repairs ex-
cept for carburetor adjustments. Be- cause a chain saw is a high-speed wood-cutting tool, special precautions
must be observed to reduce the risk of accidents. Careless or improper use of
this tool can cause serious injury.
PLAN AHEAD
Restrict the use of your saw to adult users who understand and can fol-
low safety rules, precautions, and operating instructions found in this
manual.

Wear protective gear. Always use steel-toed safety footwear with non-slip soles; snug-fitting clothing; heavy-duty,
non-slip gloves; eye protection such as non-fogging, vented goggles or face screen; an approved safety hard
hat; and sound barriers (ear plugs or
mufflers) to protect your hearing. Reg-
ular users should have hearing checked regularly as chain saw noise can damage hearing.
Secure hair above shoulder length. Do not wear loose clothing or jewelry; they
can get caught in moving parts.
Keep all parts of your body away from
the chain when the engine is running.
Keep children, bystanders, and ani- mals a minimum of 30 feet (10 me-
ters) away from the work area when starting and using the saw.
Do not handle or operate a chain
saw when you are fatigued, ill, or up- set, or if you have taken alcohol,
drugs, or medication. You must be in good physical condition and mentally
alert. If you have any condition that
might be aggravated by strenuous
work, check with doctor before oper- ating.
Do not start cutting until you have a
clear work area, secure footing, and,
if you are felling trees, a planned re-
treat path.

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 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 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 completely 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
_WARNING: Disconnect the spark plug before performing mainte-
nance except carburetor adjustments.
Have all 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 handles dry, clean, and free from oil or fuel mixture.
Keep caps and fasteners securely tightened.
Nonconforming replacement compo- nents or the removal of safety devices
may cause damage to the unit and possible injury to the operator or by-
standers. Use only Craftsman acces- sories and replacement parts as rec- ommended. Never modify your saw.
Maintain chain saw with care.
Keep unit sharp and clean for better and safer performance.
Follow instructions for lubricating and changing accessories.
Check for damaged parts. Before fur- ther use of the chain saw, a guard or
other part that is damaged should be carefully checked to determine that it
will operate properly and perform its
intended function. Check for alignment
of moving parts, binding of moving
parts, breakage of parts, mounting and
any other conditions that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced by a Sears Service Center
unless otherwise indicated elsewhere in the operator's 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 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 all fuel spills 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 refuel unit.
Empty the fuel tank before storing or transporting the unit. Use up fuel left in
the carburetor by starting the engine and letting it run until it stops.
Store the unit and fuel in an area where fuel vapors cannot reach
sparks or open flames from water
heaters, electric motors or switches,
furnaces, etc.

KICKBACKSAFETY FEATURES
_, WARNING: Tile 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 tile 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 INTHE 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 INTOYOUR SAW. YOU SHOULD USE THE SAW PROPERLY
AND CAREFULLY TO AVOID KICKBACK.
Reduced-kickback guide bars and low- kickback saw chains reduce tile 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 could result in serious injury. Do not
rely exclusively upon devices built into
your saw.

CHAIN BRAKE
The CHAIN BRAKE is a device designed to stop the chain if kickback occurs. The
chain brake activates automatically in
the event of kickback. The chain brake
activates manually if the front hand guard is pushed forward. The chain brake is disengaged by pulling the front hand guard back toward the front handle
as far as possible. CHAIN TENSION It is normal for a new chain to stretch
during the first 15 minutes of operation. You should check your chain tension frequently. See CHAINTENSION under
the MAINTENANCE section. ,_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.

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 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 mixing 3.2 ounces of oil with
1 gallon of unleaded gasoline. Included with this saw is a 3.2 ounce container of oil. Pour the entire contents of this con-
tainer into 1 gallon of gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or boat oil. These oils will cause engine damage.
When mixing fuel follow the instruc- tions printed on the oil container. Once
oil is added to the gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relat- ing 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, 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. _IWARNING: 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 tile throttle trigger.
Move ON/STOP switch to the STOP position.
STARTING POSITION

DIFFICULT STARTING (or starting a flooded engine) The engine may be flooded with too
much fuel if it has not started after 10
pulls.
Flooded engines can be cleared of ex-
cess fuel by pushing the choke/fast
idle lever in completely (to the OFF
CHOKE position) and then following the warm engine starting procedure listed
above. Ensure the ON/STOP switch is
in the ON position.
Starting could require pulling the start-
er rope handle many times depending
on how badly the unit is flooded. If en-
gine fails to start, refer to the TROU-
BLESHOOTING 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 replaced if any 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).
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 saw on firm ground. Grip the rear handle with your right hand and the front handle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain
brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain should stop immediately.
Inertia activating function control
,I_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 inches (35 cm) above a stump or other wooden surface. Release 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. 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.
Keep the chain out of dirt and sand.
Even a small amount of dirt will quickly dull a chain and thus increase the
possibility of kickback.
Practice cutting a few small logs us-
ing the following techniques to get the "feel" 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 cut for 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. Ifyou run the saw at full 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 Ai_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 ale 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.
lO
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 fall. Maintain a dis- tance of 2-1/2tree 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.
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 inthe
wrong direction.
Hinge holds tree on stump and helps control fall

FELLING LARGE TREES
(6 h_ches(15 cm) h_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. 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 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 era) above center of notch.

Closing of notch
NOTE: Before felling cut is complete, use wedges to open the cut ifnecessary
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 cut down a partially fallen tree
with your saw. Be extremely cautious with partially fallen trees that may be
poorly supported. When a tree doesn't
fall completely, set the saw aside and

Bucking is tile term used for cutting a
fallen tree to the desired log size. 'd_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.

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 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 a wedge to remove pinched saw
Turn saw OFF and use a plastic or wooden wedge to force cut open.
Overcutting begins on the top side of the log with the bottom of the saw against the log. When overcutting use light downward pressure.
Second cut
First cut on compression side of log
BUCKING WITHOUT A SUPPORT
Overcut through 1/3of the diameter of the log.
Roll the log over and finish with a second overcut.
Watch for logs with a compression side to prevent the saw from pinch-
ing. See illustrations 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)
Your first cut should extend t/3 of the diameter of the log.
Finish with your second cut.

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: Neverturn 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
_IWARNING: 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 result in serious injury.
_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 firmly gripped on the saw. Maintain secure footing and balance.
Watch out for springpoles. 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 clear branches out of the way to avoid
tripping over them.
LIMBING
Always limb a tree after it is cut down. Only then can limbing be done
safely and properly.
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. Cut from the side of the tree
opposite 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 small and freely hanging limbs. Undercutting
could cause limbs to fall and pinch the
saw.
PRUNING
_ILWARNING: 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.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cov- er items that have been subjected to operator abuse or negligence. To re- ceive full value from the warranty, the operator must maintain unit as
instructed in this manual. Various ad- justments will need to be made period-
ically to properly maintain your unit.
Once a year, replace the spark plug, air filter, and check guide bar and
chain for wear. A new spark plug and air filter assures proper air-fuel mixture
and helps your engine run better and last longer.
CHECK FOR DAMAGED OR WORN PARTS
Contact your Sears Service Center for replacement of damaged or worn parts.
NOTE: It is normal for a small amount of
oil to appear under the saw after engine 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 STOPposition. Make sure engine stops; then restart engine
and continue=
Fuel Tank - Do not use saw iffuel tank shows signs of damage or leaks=
Oil Tank - Do not use saw if oil tank shows signs of damage or leaks.

CHECK CHAIN TENSION
_lk WARNING: Wear protective
gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your
saw. Always check chain tension each
time you use and refuel your saw.
1. Use the screwdriver end of the
chain adjustment tool (bar tool) to move chain around guide bar to
ensure kinks do not exist. The chain should rotate freely.

2. Loosen bar nuts until they are finger tight against the clutch cover.
3. Turn adjusting screw clockwise un- til chain solidly contacts bottom of
guide bar rail.
4. Using bar tool, roll chain around
guide bar to ensure all links are in bar groove.
5. Lift up tip of guide bar to check for
sag. Release tip of guide bar, then
turn adjusting screw until sag does
not exist.
6. While lifting tip of guide bar, tighten
bar nuts securely with the bar tool.

7. Use the screwdriver end of the bar tool to move chain around guide
bar.
8. If chain does not rotate, it is too tight. Slightly loosen bar nuts and
loosen chain by turning the adjust- ing screw 1/4 turn counterclock-
wise. Retighten bar nuts.
9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate
the saw if the chain is loose.
_,WARNING: If the saw is oper- ated with a loose chain, the chain
could jump offthe guide bar and result in serious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARP-
ENING. 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.
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 bar nuts and clutch cover. Remove bar and chain
from saw.
Clean the oil holes and bar groove after each 5 hours of operation.
