completely and securely assembled.
Always replace bar, chain, hand
guard, chain brake, or other parts immediately if they become damaged,
broken, or are otherwise removed.
MAINTAIN
YOUR
SAW IN GOOD
WORKING ORDER
• Have all chain saw service performed by a qualified service dealer
except 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 ADJUSTMENTS.
• Keep the handles dry, clean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
tightened.
• Nonconforming replacement components or the removal of safety devices
may cause damage to the unit and
possible injury to the operator or bystanders. Use only Craftsman accessories and replacement parts as recommended. 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 further 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 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 container 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 vapors 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.
_'_
._,:f.¢'
Clear The Working
Kickback Path
Area
Z_
LI_ WARNING:
Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood 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 dig into the object, which
stops the chain for an instant. The
result is a lightning fast, reverse
reaction which kicks the guide bar up
and back toward the operator.
• Pinch-Kickback
can occur when the
the wood closes in and pinches the
moving saw chain in the cut along the
top of the guide bar and the saw chain
is suddenly stopped. This 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 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 stopping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw.
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can happen.
With a basic understanding of kickback, you can reduce the element of
surprise which contributes to accidents.
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keep working area free from obstructions such as other trees, branches,
rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your saw
chain could hit while cutting.
• When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
• Keep saw chain sharp and properly
tensioned. A loose or dull chain can
increase the chance of kickback. Follow 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 at a
slower speed, there is greater chance
of kickback occurring.
• Use extreme caution when reentering
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 pinch 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 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.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or wood.
Never use metal to hold the cut open.

SAFETY
FEATURES RESENT AND YOU SHOULD NOT AS-
'_ WARNING:
The following features
are included on your saw to help reduce
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 contacting the chain if your hand slips off the
front handlebar.
• Position of front and rear handlebars:
designed with distance between handles 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 resistance in controlling the pivot of the
saw back toward the operator if kickback occurs.
• Reduced-Kickback Guide Bar: designed with a small radius tip which
reduces the size of the kickback danger 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.
Tip Guide Bar
_._._,
Large Radius [
Tip Guide Bar
Small Radius
'_'
• Low-Kickback Chain: has met kickback performance requirements when
tested on a representative sample of
chain saws below 3.8 cubic inch displacement specified in ANSI B175.1.
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 rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the
danger zone with any hard object.
Kickback can also be caused by
pinching the saw chain along the top
of the guide bar. This action may push
the guide bar rapidly back toward the
operator. Either of these events may
cause you to lose control of the saw
which could result in serious injury or
even death. DO NOT RELY UPON ANY
OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK, Reduced-kickback
guide
bars and low-kickback
saw chains reduce 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 authorized Sears Service Center. Take
your unit to the place of purchase or to
your nearest Sears Service 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 safety devices
built into your saw.

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

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,
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 logs using the following steps. This will help
you 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.
• 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.

TECHNIQUES
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 the tree does make 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 ofthe tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the direction of tree lean.
• Weight and branches on one side.
• Surrounding trees and obstacles.
• Look for decay and rot. If the trunk is
rotted, it can snap and 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.
• Remove dirt, stones, loose bark,
nails, staples, and wire from the tree
where cuts are to be made.

• After removing the wood from the
notch, make the felling cut on the opposite 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.

• Be alert to signs that the tree is
ready to fall: cracking sounds, widening 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.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
,_ik 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.
TYPES OF CUTTING USED FOR
BUCKING
all.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 saw and carefully reenter the cut.
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
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.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.

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 pinching. See illustrations above 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 1/3 of the
diameter of the log.
• Finish with your second cut.
_WARNING:
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. Allowing such
contact can result in serious injury.
,_/L WARNING:
Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
• Watch out for springpoles. Springpoles
are small size limbs which can whip
toward you, or pull you off balance.
Use extreme caution when cutting
small size limbs.
• Be alert for springback 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 tripping over them.

Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the carburetor. If you require further assistance or are unsure about performing
this procedure, call our customer assistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, dirty fuel filter,
or flooding may give the impression of
an improperly adjusted carburetor.
Check these conditions before adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the following conditions:
• Chain moves at idle. See IDLE
SPEED-T under adjusting procedure.
• Saw will not idle. See IDLE SPBED-T
and LOW SPEED MIXTURE-L under
adjusting procedure.
• Engine dies or hesitates when it
should accelerate. See ACCELERATION CHECK under adjusting
procedure.
• Loss of cutting power. See HIGH
SPEED MIXTURE - H under adjusting
procedure.
There are three adjustment screws on
the carburetor. They are labeled H, L,
and T. They are located in the area just
above the primer bulb.

,_ WARNING:
Perform the following
steps after each use:
• Allow the engine to cool, and secure
the unit before storing or transporting.
• Store chain saw and fuel in a well
ventilated area where fuel vapors
cannot reach sparks or open flames
from water heaters, electric motors or
switches, furnaces, etc.
• Store chain saw with all guards in
place and position chain saw so that
any sharp object cannot accidentally
cause injury.
• Store chain saw well out of the reach
of children.
SEASONAL STORAGE
Prepare your unit for storage at the
end of the season or if it will not be
used for 30 days or more.
If your chain saw is to be stored for a
period of time:
• Clean saw thoroughly before storage.
• Store in a clean dry area.
• Lightly oil external metal surfaces
and guide bar.
• Oil the chain and wrap it in heavy paper or cloth.
FUEL SYSTEM
Under FUELING ENGINE in the OPERATION section of this manual, see message labeled IMPORTANT regarding
the use of gasohol in your chain saw.
Fuel stabilizer is an acceptable alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
containers. Run engine at least 5 minutes after adding stabilizer.
Craftsman 40:1,2-cycle
engine oil (air
cooled) is blended with fuel stabilizer. If
you do not use this Sears oil, you can
add a fuel stabilizer to your fuel tank.
ENGINE
• Remove spark plug and pour 1 teaspoon of 40:1,2-cycle
engine oil (air
cooled) through the spark plug opening. Slowly pull the starter rope 8 to
10 times to distribute oil.
• Replace spark plug with new one of
recommended type and heat range.
• Clean air filter.
• Check entire unit for loose screws,
nuts, and bolts. Replace any damaged, broken, or worn parts.
• At the beginning of the next season,
use only fresh fuel having the proper
gasoline to oil ratio.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if it starts
to rust.
