away from the chain when the engine is running.
• Cut wood only. Do not use your saw to pry or shoveaway
limbs,roots, or other objects.
• 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 or kerr.
• Use extreme caution when cutting small size brush
and saplings. Slender materialcan catch the chain and
be whipped toward you or pull you off balance.
• Be alert for springback when cuttinga limbthat is under
tensionso you will not be struck by the limb or saw when
the tension in the wood fibers is released.
• Do not put pressure on the saw at the end of a cut.
Applyingpressure can cause you to lose controlwhen the

"Customer Responsibilities"section of this manual. For
example,if impropertoolsare used to remove or ho{dthe
flywheelwhen servicingthe clutch, structuraldamage to
the flywheelcan occurand cause the-flywheel to burst.
• Make certain the chain stops moving when the throttle
trigger is released, For correction,refer to 'Carburetor
Adjustments."
• Stop the saw if the chain strikes a foreign object.
Inspectunitand repair or replace parts as necessary.
• Disconnect the spark plug before performing any
maintenance exceptfor carburetor adjustments.
• Never modify your saw in any way. Use only SEARS '

reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
• Store unit so the chain cannot accidentally cause injury.
• Store the unit out of the r_ach of children.
KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.
WARNING:
Kickback
Path
KICKBACK CAN OCCUR WHEN THE MOVING CHAIN CONTACTS AN OBJECT ATTHE
UPPER PORTION OFTHETIP OFTHE GUIDE
BAR OR WHEN THE WOOD CLOSES IN AND
PINCHES THE CHAIN IN THE CUT. CONTACT
AT THE UPPER PORTION OF THE TIP OF
THE GUIDE BAR 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. IF THE
CHAIN IS PINCHED ALONG THE TOP OF
THE GUIDE BAR, THE GUIDE BAR CAN BE
DRIVEN
RAPIDLY BACK TOWARD THE
OPERATOR. EITHER OFTHESE REACTIONS
CAN CAUSE LOSS OF SAW CONTROL
WHICH CAN RESULT IN SERIOUS INJURY.
DO NOT RELY ONLY ON THE SAFETY
DEVICES PROVIDED WITH YOUR SAW. AS
A CHAIN SAW USER, YOU MUST TAKE
SPECIAL SAFETY PRECAUTIONS TO HELP
KEEP YOUR CUTTING JOBS FREE FROM
ACCIDENT OR INJURY.

REDUCE THE CHANCE OF KICKBACK
• Recognize that kickback can happen. With a basic
understandingof kicl_ack,you can reduce the element of
surprisewhichcontributesto accidents.
* Never let the moving chaincontact any object at the tip
of the guide bar. Figure2.
. Keep the working area free from obstructions such as
other trees, branches,rocks,fences,stumps,etc.Figure3.
Eliminate or avoidany obstructionthat your chain couldhit
while you are cuttingthrougha particularlog or branch.
, Keep your chain sharp and properly tenaioned.A loose
or dull chaincan increasethe chance of kickbackto occur.
Follow manufacturer'schainsharpeningand maintenance
instructions.Check tension at regular intervals with the
engine stopped,neverwith the engine running.Make sure
the bar clamp nutsare securelytightenedafter tensioning
the chain.
• Begin and continue cutting at full throttle. If the chain is
moving at a slowerspeed,there is greaterchance for kickback to occur.
• Cut one log at a time.
• Use extreme caution when re-entering a previous cut.
• Do not attempt plunge cuts.
• Watch for shifting logs or other forcesthat could close a
cut and pinch or fall intochain.
° Use the Reduced-Kickback Guide Bar and LowKickback Chain specked for yoursaw.

SAFETY FEATURES
MAINTAIN CONTROL
• Keep a good, firm grip on the saw with both hands
when the engine is running and don't let go. Figure4.
A firm grip can neutralize kickback and help you maintain
controlof the saw. Keep the fingersof your left hand encircling and your left thumb under the front handlebar.Keep
your righthand completely around the rear handle whether
you are right handed or left handed. Keep your left arm
straight withthe elbow locked,
• Position your left hand on the front handlebar so it is
in a sl_aight line with your right hand on the rear harp
die when making bucking cuts. Figure4. Never reverse
right and left hand positionsfor any type ofcutting.
• Stand with your weight evenly balanced on both feel
• Stand slightly to the left side of the saw to keep your
body from being in a direct line with the cutting chain.
Figure4.
• Do not overreach. You couldbe drawnor thrown offbalance and lose control of the saw.
• Do not cut above shoulder heighL It is difficult to maintaincontrol of saw above shoulderheight.
UNDERSTANDING
REACTWE FORCES
Pinch-Kickback and Puff-In occur when the chain is suddenly stopped by being pinched, caught, or by contacting a foreign object in the wood.This stoppingof the chain
resultsin a reversal of the chain force used to cut wood and
causesthe saw to move in the oppositedirectionof thechain
rotation.Either reaction can resultin loss of control and possibleseriousinjury.
• Pinch-Kickback
-occurs when chain on top of guide bar is suddenly
stopped.
- rapidlyd/_vessaw straightback towardoperator.
• PulHn
- occurswhen the chain on the bottomof the guide bar is
suddenlystopped.
- pulis the saw rapidly forward.

specially blended w_ fuel stabilizers.If you do not use this
Sears oil, you can add a fuel stabilizer to your fuel tank.
40:1 2-CYCLE AIR-COOLED ENGINE OIL
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)is
stronglyrecommended.This oil is specificallyblended with
fuel stabilizersfor increased fuel stability (extends fuel I_fe
up to 5 times longer) and reduced smoke.
GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life,we recommendyou
use Craftsman chain saw bar oil. if Craftsmanbar oil is not
available, you may use a goodgrade SAE30 oiluntilyou are
able to obtain Craftsman brand,The oi! outputis automatically metered during operation.Your saw will use approximately one tank of bar oil for everytank of fuel mix. Always
fill the bar oil tank when you fill the fuel tank.
If CRAFTSMAN 40:1 2-cycleengi_neoil (AIR-COOLED).is
not avellabie, use a good quality 2-cycle engine oil (AIRCOOLED) that has a recommended fuel mix ratio of 40:1.
IMPORTANT! Do not use:
• AUTOMOTIVE OIL
• BOAT OILS (NMMA, BIA, etc.)
GASOLINE
The two-cycle engine on thisproductrequiresa fuel mixture
of regular unleeded gasoline and a quality 40:1
2-cycle engine oi! (AIR-COOLED) for lubricationof the bearings and other moving parts.The correctfuel/oil mixture is
40:1 (see Fuel Mixture Chart).Too littleoilorthe incorrectoil
type will cause poor performanceand may causethe engine
to overheat and seize.
Gasoline and oll must be premixed in a clean approvedfuel
container.Always use fresh regularunleadedgasoline.
This engine is certified to operateon unleadedgasoline.
£:=?_
IMPORTANT: Experience indicates that alcohol blended
fuels called gasohol (or using ethanol or methanol) can
attract moisture, which leads to oil/gasseparation and formarion of acids during storage.Acidicgas can damage the
fuel system of an engine while in storage.To avoid engine
problems, the fuel system shouldbe emptiedbefore storage
for 30 days or longer, Drain the gas tank, then run the fuel
out of the carburetor and fuel lines by starting the engine
and letting it run until it stops. Use fresh fuel next season.
See STORAGE instructionsfor additionalinformation.Never
use engine or carburetor cleaner productsin the fuel tank or
permanent damage may occur.
These oils do not have proper additives for 2-cycle

GENERAL
OPERATION
TIPS
• cut wood only. Do not cut metal; plastics;masonry;nonwood building materials;etc.
• Stop the saw if the chain strikes a foreignobject.Inspect
the saw and repair or replace parts as necessary.
• Keep the chain out of dirt and sand. Evena sma!lamount
of dirt will quickly dull a chain and thus increasethe possibilityof kickback.
....
=
To getthe =feel"of usingyour saw beforeyou begin a major
sawing operation, practice cutting a few small Jogsusing
the following technique:
• Accelerate engine to fullthrottle by squeezingthe throttle
trigger before entering cut.
•
•
•
•
Never cut with engine at partial speeds.
Begin cuttingwith the saw chassisagainst the log.
Keep engine at full throttleduring cuttingprocedure.
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. If you run the unit at
full throttle without cutting,unnecessary wear can occur
to the chain, bar, and engine.
• To avoid losingcontrolwhen completing the cut, do not
put pressure on the saw duringthe end of the cut.
• Stop engine before setting unitdown after operation.

AVOID REACTIVE PINCH FORCES
WARNING:
IF SAW BECOMES PINCHED OR HUNG IN A
LOG, DO Nor 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. RESTARTTHE 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.
Pinch*Kickbackand Pull-in occur when the chain is suddenly stopped by being pinched, caught, or by contacting
a foreign object in the wood. 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. Pinch-Kickback drives the saw
straight back toward the operator: Pull-In pulls the saw
away from the operator.Eitherreaction can resultin loss of
controland possiblyserious injury,
TO AVOID PINCH-KICKBACK:
• Be extremely aware of situationsor obstructionsthat 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
under-cut when bucking.
KICKBACK CAN OCCUR WHEN THE MOVING CHAIN CONTACTS AN OBJECT AT THE
UPPER PORTION OFTHETIP OFTHE GUIDE
BAR OR WHEN THE WOOD CLOSES IN AND
PINCHES THE SAW CHAIN IN THE CUT.
CONTACT AT THE UPPER PORTION OF THE
TIP OF THE GUIDE BAR CAN CAUSE THE
CHAINTO DIG INTOTHE OBJECT AND STOP
THE CHAIN FOR AN INSTANT.THE RESULT
IS A LIGHTNING FAST, REVERSE REACTION
WHICH KICKS THE GUIDE BAR UP AND
BACK TOWARD THE OPERATOR, IF THE
SAW CHAIN IS PINCHED ALONG THE TOP
OF THE GUIDE BAR, THE GUIDE BAR CAN
BE DRIVEN RAPIDLY BACK TOWARD THE
OPERATOR. EITHER OFTHESE RE.ACTIONS
CAN CAUSE LOSS OF SAW CONTROL
WHICH CAN RESULT IN SERIOUS INJURY.
..::_'i
TO AVOID PULL-IN:
,, Always begin cuffing with the engine at full throttle and
the saw housing against wood.
• Use wedges made,of plasticor wood, (never of metal) to
hold the cut o_pen.

FELLING
WARNING:
IF THE TRUNK OR LIMBS ARE ROTTING,
THEY CAN FALL UNEXPECTEDLY AND
CAUSE SERIOUS INJURY,
AS YOU MAKE YOUR FELLING CUT, IF THE
SAW APPEARS TO BE BINDING, THE TREE
IS STARTING TO FALL IN THE WRONG
DIRECTION, IMMEDIATELY STOP THE SAW
AND USE A FELLING WEDGE AND MAUL

DETERMINE THE NATURAL FALL DIRECTION
• Wind - A tree evenly balanced willfall in the same direction the wind is btowing.
• Lean - Use a carpenter's level or plumb bob to determine if tree has a natural lean. A leaning tree willtend to
fall in direction of lean.
• Shape - A tree will tend to fail towards side that is more
heavily branched.
• Other Factors- Contacting or nearby trees, buildings,or
wires can influencethe direction the tree wilt fall.
CUTTING
PROCEDURE
(Fig. 12)
Afterdetermining the Natural Fall Direction,the treeshould
be cut as follows:
IMPORTANT: BEFORE FELLING A TREE, MAKE SURE
YOU HAVE AT LEAST 3 FELLING WEDGES AND A
MAUL (HAMMER) AVAILABLE FOR USE IF NEEDED.
:23_
/
• Use some means to visually mark the Natural Fall
Direction.
* Mark your notch cut on the Natural Fall Directionside of
the tree approximately 18-24 inches above the ground.
• Cut top of the notch first at a 45 degree angle. Saw
through 1/3 of the width of the tree.
• Cut bottom of the notch at a 45 degree angle until you
meet the top notch cut. Remove notch of wood.
• On the side of the tree opposite the notchcut, make the
felling cut. The felling cut should be 2 inches above the
center point of the notch cut. Before the felting cut is
complete, use wedges to open the cut when necessary
to control the direction of the fall. Use wood or plastic
wedges, but never steel or iron, to avoid kickbackand
chain damage.
• Cracking sounds, widening of the felling cut, movement
in the upper branches are all signs that the tree is ready
to fall.
• As tree begins to fall, turn off saw, and move quickly
away from direction of fall
Figure 12
If your chain saw binds in the felling cut, you have three
options:
• If the wrong direction of fall is acceptable, carefully
remove the felling wedge. C_ deeper in the notchside of
the tree untiltree starts to fall.
• If the wrong direction of fall is not acceptable, attempt to
use one or more felling wedges to force the tree in the
original direction of fall. Do so by driving the wedges
deeper into the felling cut.
• Keep everyone away from the tree in all directions and
•then seek professional help!
FELLING TIPS
• Clear the work area of debris where you can have secure
footing.
• 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.
• Plan to stand on the up-hill side when cuttingon a slope.
• Plan a clear retreat path to the rear and diagonal to the
line of fall.
• Large buttress roots should be removed prior to notch
CUt.
" Use a wedge if there is any chance that the tree will not
fall in the desired direction.
• We recommend you cut branches below shoulder height
before felling tree. (See Limbing and Pruning).
Be alert to signs that the tree is ready to fall:
• Cracking sounds.
• Widening of the felling cut.
° Movement in the upper branches.

BUCKING
Bucking is cutting a fallen tree to the desired log size.
TYPES
OF CUTTING (Fig. 13)
• Overcutting - begin on the top side of the log with the
bottom of the saw chassis against the log; exert light
pressure downward.
• Undercutting-begin on the undersideof the tog with the
top of the saw chassis against the log; exert light pressure upward. During undercutting,the saw will tend to
push back at you,Be prepared for this reaction and hold
the saw firmly to maintain control,
BUCKING USING A SUPPORT
(Fig. 15 & 16)
Anotherlog or a stand, such as a sawhorse, may be used
as supportswhen bucking.
• Area A - Undemut 1/3 of the way through the log.
- Finish with an ovetcut,
• Area B - Overcut 1/3 of the way through the log.

• 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 such as ira bl6wn down area. Drag the logs into
a clear area before cutting by pulling out exposed and
cleared logs first.

MOVE AT IDLE SPEED.
If engine does not start, it may be flooded, if in doubt, read
the section on fleoded engine in the starting section of this
manual prior to beginning any adjustments.
The carburetor has been adjusted at the factory for sea
level conditions.Adjustments may become necessaryif the
saw is used at significantly higher altitudes or if you notice
any of the following conditions:
• Chain moves when the engine runs at idle speed. See
"ldte Speed Adjustment."
• Saw will not idle. See "Idle Speed Adjustment" and "Low
Speed Mixture Adjustment."
• Engine dies or hesitates when it should accelerate. See
"Aoceteration Adjustment."
• Loss of cutting power which is not corrected by air filter
cleaning. See "High Speed Mixture Adjustment."

IMPORTANT: It is importantto prevent gum deposits from
formingin essentialfuel system parts such as the carburetor, fuel filter, fuel hose or tank during storage. Also, expedence indicatesthat alcohol blended fuels, those that use
ethanol or methanol (called gasohol or oxygenated fuel),
can attract moistureand form acidic gas which willdamage
your engine. To avoid engine problems, the fuet system
should be emptied beforestorage of 30 days or longer.
Fue! stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add stabilizer to the gasolinein the fuel tank or fuel storage container.Always follow the mix instructionsfound on stabilizer
containers.Run engine at least 5 minutes after adding stabilizer to allow the stabilizerto reach the carburetor.
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
specially blended with fuel stabilizer.If you do not use this
Sears oil, you can add a fuel stabilizer to your fuel tank.
