• Keep the workln S area free from obstructions such
as other trees, branches, rocks, fences, stumps, etc.
Rgura 3. Eliminate or avoid a..nyobstructionthat your
chain couldhitwhile you are cumngthrougha particular
log or branch.
• Keep your chain sharp and properly tensioned. A
loose or dull chain can increasethe chance of kickback
to occur. Followmanufacturer's chain sharpening and
maintenance instructions. Check tension at regular intervals with the engine stopped, never with the engine
running. Make sure the bar clamp nuts are securely
tightenedafter tensioningthe chain.
• Begin and continue cutting at full throttle.
If the
chain is moving at a slower speed, there is greater
chance for Idckbackto occur.
Cut one log at s time.
Use extreme caution when re-enlarlng a previous

FUEL STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing the
formationoffuelgum depositsduringstorage. Addstabilizer
to gasoline in fuel tank or storagecontainer. Always follow
the fuel mix ratio found on the stabilizer container. Run
engine at least5 minutesafter addingstabilizer to allow the
stabilizerto reach the carburetor.You do not have to drain
the fuel tank for storage if you are using fuel stabilizer.
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) Is
speciallyblended with fuel stabilizers.If you do not use this
Sears oil, you san add a fuel stabilizer (such as Craftsman
No. 33500) to your fuel tank.
2-CYCLE OIL:
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
specially blended with fuel stabilizers.If you do not use
this Sears oil, you can add a fuel stabilizer (such as
Craftsman No. 33500) to your fuel mix. See Gasoline
and oil mixture"instructionsbelow.
If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)
is not available, use a good quality40:1 2-cycle engine oil
(AIR-COOLED) that has a recommendedfuel mix ratio
40:1.
IMPORTANTI Do not usa:
GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life, we recommend
you use CPaftsmanchain saw bar oil. If Craftsman bar oil
is not available, you may use a good grade SAE30 oil
until you are able to obtain Craftsman brand.The oil output is automaticallymetered during operation.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.
• AUTOMOTIVE OIL
• BOAT OILS (NMMA, BIA. etc.)
These oils do not have properadditives for 2.-cycle (AIRCOOPED) engines and can cause engine damage.
GASOUNE
GASOUNE
The two-cycle engine on this productrequiresa fuel mixture
of regularunleadedgasoline and a highquality 40:1 2-cycle
engineoil (AIR-COOLED) for lubricationofthe beadngs and
other moving parts. The correct fuel/oil mixture is40:1 (see
Fuel MixtureChart). Too little oil orthe incorrectoil type will
cause poorperformanceand may cause the engine to overheat and seize.
AND OIL MIXTURE
MIX GASOLINE AND OIL AS FOLLOWS:
• Consult chart for correctquantities.
• Do not mix gasoline and oildirectly in the fuel tank.
FOR ONE GALLON:
Pour 3.2 ounces of high quality, 2-cycle engine oil
(AIR-COOLED) into an empty, approved one gallon
gasoline container.
• Add one gallonof regular
unleededgasoline
to the
galloncontainer,
then securelyreplacethe cap.
Shake thecontainer
momentarily.
• The mixture
isnow readyforuse. Fuelstabilizer
can
be added atthis
timeif
desired;
follow
mixinginstructionson thelabel.
Gasoline and oil must be pmmixed in a clean approved fuel
container. Always use fresh regular unleaded gasoline.
This engine is certified to operate on unleaded gasoline.
IMPORTANT:
Experience indicates that alcohol
blended fuelscalled gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas 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 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 additional information. Never use engine
or carburetorcleaner products in the fuel tank or permanent damage may occur.

THE NATURAL FALL DIRECTION
Wind - A tree evenly balanced will fall in the same direction the wind is blowing.
Lean - Use a carpenter's iovel or plumb bob to determine iftree has a natural lean. A leaning tree willtend to
fall in direction of lean.
Shape- A tree willtend to fall towards side that is more
heavily branched.
Other Factors- Contacting or nearby trees, buildings,or
wires can influencethe direction the tree will fall.
CUTI'ING
PROCEDURE
(Fig. 12)
After determiningthe Natural Fall Direction, the tree should
be cut as follows:
IMPORTANT: BEFORE FELLING ATREE, MAKE SURE
YOU HAVE AT LEAST 3 FELLING WEDGES AND A MAUL
(HAMMER) AVAILABLE FOR USE IF NEEDED.
•
Use some means to visually mark the Natural Fall
Direction.
• Mark your notchcut on the Natural Fall Directionside of
the tree approximately18-24 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 untilyou
meet the top notch cut. Remove notch of wood.
• On the side of the tree opposite the notchcut, make the
fellingcut. The fellingcut should be 2 inches above the
center point of the notch cut. Before the felling cut is
complete, use wedges to open the cut when necessary
to controlthe direction of the fall. Use wood or plastic
wedges, but never steel or iron, to avoid kickback and
chain damage.
• Cracking sounds,widening of the fellingcut, movement
in the upper branches are aUsignsthat the tree is ready
to fall.
•
If your chain saw binds in the fellingcut, you have three
options:
• If the wrong direction of fall is acceptable, carefully remove the fellingwedge. CUt deeper in the notch side of
the tree until tree starts to fall.
• If the wrengdirectionof fall isnot acceptable,attemptto
use one or more felling wedges to force the tree in the
original direction of fall. Do so by driving the wedges
deeper intothe felling cut.
• Keep everyone away from the tree in all directions and
then seek professional helpl
OPERATION USE/TIPS
•
Clear the work area of debris where you can have secure footing.
• MakesurethereisenoughroomforthstreetofalL Maintain a distanceof 21/2 tree lengthsfromthe 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 standon the uphill side whencuffingon a slope.
• Plan a clear retreat path to the rear and diagonal to the
line of fall.
• Large buttressroots should be removedprior to notch
cut.
• Use a wedge if there is any chance thatthe tree will not
fall in the desired direction.
• We recommendyou cutbranches belowshoulderheight
before fellingtree, (See LImbingand Pruning).
Be alert to signsthat the tree is ready tofall:
• Crackingsounds.
• Widening of the telling cut.
• Movement In the upper branches.
As tree begins to fall, turn off saw, and move quickly
away from directionof fall.
-11-
OPERATION - GENERAL
OPERATION
• Begin cuffingwith the saw chassis against the log.
• Keep engine at full throttle dudngcuttingprocedure.
• 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 throttletdgger as soonas the cut iscompleted, anowin_ the engine to idle. I1you runthe unit
at full throttlewithout cutting,unnecessarywear can
occur to the chain, bar, andengine.
• To avoid losingcontrol when completingthe cut, do
not put pressureon the saw dudngthe end of thecut.
• Stop engine beforesetting unitdownafter operation.
USE/TIPS
•
Cutwood only.Do not cut metal; plastics;masonry;nonwood buildingmaterials;etc.
• Stopthe saw ifthe chainstdkes a foreignobject. Inspect
the saw and mpetr or replace parts as necessary.
• Keep the chain out of dirt and sand. Even a small
amountof dirtwillquicklydull a chain and thus increase
the possibilityof kickback.
To get the "feel"of usingyoursaw before you begin a major
sawingoperation,practicecutting a few small logsusingthe
followingtechnique:
• Accelerate engine to full throttle before enteringcut
by squeezing the throttle tdgger.
• Never cut with engine at partial speeds.
OPERATION SAFETY - GENERAL
GENERALSAFETY
AVOID REACTIVE
PINCH FORCES
Pinch-Kickbackand Pull-In occurwhen the chain issuddenly stopped by being pinched, caught, or by contactinga foreignobjectin the wood. This suddenstoppingof
the chain resultsin a reversal of the chainforce used to
cut wood and causes the saw to move in the opposite
direction of the chain rotation. Pinch-Kickbackdrives
the saw straightback toward the operator. Pult-ln pulls
the saw away from the operator. Eitherreaction can resuit in loss of controland possiblyseriousinjury.
WARNING
IF SAW BECOMES
PINCHED OR HUNG IN A
LOG, DO NOT 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.
KICKBACK CAN OCCUR WHEN THE
MOVING CHAIN CONTACTS AN OBJECT
AT THE UPPER PORTION OF THE TIP OF
THE 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 CHAIN TO DIG INTO THE
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 i
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 OF THESE REACTIONS CAN
CAUSE LOSS OF SAW CONTROL WHICH
CAN RESULT IN SERIOUS INJURY.
-12_
TO AVOID PINCH-KICKBACK:
• Be extremely aware of situationsor obstructionsthat
can cause matedai to pinch the top of or otherwise
stop the chain.
• Do not cut more than one log at a time.
• Do not twistthe saw as the bar iswithdrawnfroman
under-cutwhen bucking.
TO AVOID PULL-IN:
• Always begin cutting with the engine at full throttle
and the saw housing against wood.
• Use wedges made of plastic or wood, (never of
metal) to hold the cut open.

SERVICE AND ADJUSTMENTS
CARBURETOR
ADJUSTMENTS
Carburetor adjustment Is critical and If done Improperly can permanently damage the engine as well as the
carburetor. Please read all Instructions and consult the Troubleshooting section of this manual before
beginning this process. If the engine does not operate according to these Instructions after repeating the
adjusting steps, do not use the unit. For further 8ssistsnca, please call our customer aselstsnca hotllne at
1-800-235-5878.
If engine does not start, it may be flooded. If in doubt,
read the section on flooded 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 necessary if
the saw is used at significantlyhigher altitudesor if you
notice any of the following conditions:
• Chain moves when the engine runs at idle speed. See
"Idle Speed Adjustment."
• Saw will not idle. See =Idle Speed Adjustment"and
=Low SpeedMixture Adjustment;
• Engine dies or hesitates when it should accelerate.
See "Acceleration Adjustment."
• Loss of cutting power which is not correctedby air tilter cleaning. See "High Speed Mixture Adjustment."
NOTE: There are three adjustments on the carburetor.
• The Idle Speed Adjustment is marked with the letter
• The two remaining adjustments on the carburetor
are the mixture adjustments. One is marked =L"for
low speed, and the other "H"for high speed.
A
WARNING:
THE CHAIN WILL BE MOVING DURING
MOST OF THIS PROCEDURE. WEAR
YOUR PROTECTIVE EQUIPMENT AND
OBSERVE ALL SAFETY PRECAUTIONS.
CARBURETOR
PRESETS (Fig. 50)
If your engine will not start due to suspected improper
carburetor adjustment, the following presets may be requirad. If used, it is recommended that all steps within
the adjustment procedure be completed in order to
assure a properlyset carburetor. If presets are not needed, proceed to section "Idle Speed Adjustment."
When making adjustments, be careful not to force the
plastic limiter caps beyond the stops or damage will
OCCUr.
Very small adjustments can affect engine performance.
It is important to make slight adjustments and test performance before proceeding. Each adjustment should
be no more than 1/16 of a rum.
• Turn bothof the mixture adjustments countemlockwise untilthey stop.
• Turn the idle speed adjustment clockwise until it
stops. Now turn countemlockwise 4-1/2 turns.
• If engine fails to start after performing carburetor presets, the unit may be flooded. Review the "Difficult
Starting"section of the manual. If problems continue
call the 1-800 number listed on the front cover of this
manual for further assistance.
• Start the engine and operate for three (3) minutes to
warm up.Go to "AdjustingProcedure."
IN "LOW SPEED MIXTURE ADJUSTMENT;' RECHECK IDLE SPEED AFTER
EACH ADJUSTMENT.THE CHAIN MUST
NOT MOVE AT IDLE SPEED,

PROCEDURE
HIGH SPEED MIXTURE ADJUSTMENT"H"
IMPORTANT: DO NOT OPERATE ENGINE AT FULL
THROTTLE FOR PROLONGED PERIODS WHILE
MAKING HIGH SPEED ADJUSTMENTS AS DAMAGE
TO THE ENGINE CAN OCCUR.
IDLE SPEED ADJUSTMENT -'r"
• Allow the warm engine to idle.
• Adjust the Idle Speed until the engine continuesto run
without stalling and without the chain moving.
- Turn clockwise to increase engine speed if engine
stalls or dies.
- Turn counterclockwise to slow engine down and/or
to keep the chain from turning.
No further adjustments are necessary if chain does
not move at idle speed and if performance is satisfactory.
LOW SPEED MIXTURE ADJUSTMENT "L"
• Allow engine to idle.
• Turn the Low Speed Mixture Adjustmentslowlyclockwise untilthe RPM starts to drop.Note the position.
• Turn the Low Speed Mixture Adjustmentslowlycountemlockwise until the RPM speeds up and starts to
drop again. Note the position.
• Set the Low Speed Mixture at the midpoint between
the two positions.
• Make a test cut.
• Based on pedormance ofthe saw whilecutting, adjust
the high speed mixture in 1/16 turn increments as follows:
- Clockwiseif saw smokes or loses power in the cut.
Do not adjust for best power by soundor speed, but
judge by how well the saw performs in the cut.
- Counterclockwiseif the saw has speed while out of
the cut, but dies in the cut or lacks power while cutting.
• Repeat the test cut.
• Continue with 1/16 turn adjustmentsuntilthe saw performanceis acceptable while cutting.
• After completingadjustments,check for acceleration.
ACCELERATION CHECK
• If the engine dies or hesitatesinstead of accelerating,
turn the Low Speed Mixture Adjustment1/16 of a turn
at a time Counterclockwiseuntil you have smooth
acceleration.
• Check the idle speed for stability and no chain movement. Adjustas necessary.
• Recheck for smooth acceleration and stable idle.
Repeat process as necessary for acceptable perforrnance.

ENGINE
Never use engineor carburetorcleaner productsin the fuel
tank or permanent damage may occurto fuel system Components.
Follow these instructions:
1. Drain the fuel from the unit intoan approved
fuel container.
2. Drain the fuel linesand carburetor by starting
the engine and letting it run untilit stops.
3. Allow the engine to cool before storage.
IMPORTANT:
It is important to prevent gum deposits
from formingin essentialfuel system partssuch as the carburetor, fuel filter, fuel line, or tank during storage. Also,
experience indicates that alcohol blended fuels called
gasohol (or using ethanol or methanol) can attract moisture, which leads to oiVgas separation and formation of
acids during storage which will damage your engine. To
avoid engine problems,the fuel system shouldbe emptied
before storage of 30 days or longer.
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. Alwaysfoilewthe mix instructionsfound on stabilizer container. Run engine at least 5 minutes after adding stabilizer to allow stabilizer to reach the carburetor.
Craftsman 40:1 2-cycle engine oil isspeciallyblended with
fuel stabilizers. If you do not use this SEARS oil, you can
add a fuel stabilizer (such as Craftsman #33500) to your
fuel tank.
• Remove spark plug and pour 1 teaspoon of40:1 oil mix
through the spark plug opening. Slowlypullthe starter
rope 8 to 10 times to distribute oll to inner engine surfaces.
• Replace spark plug with a new one of the recommended type and heat range. Refer to "ProductSpecifications".
• Cleaneirfilter. Refer to"Customer Responsibilities*.
• Reinstallall covers and hardware removedfor access;
tighten all screws and fasteners.
• Checkentireunitforleosescrews, nuts, andboits. Replace any damaged, broken, or worn parts.
• Use fresh fuel having the proper gasolineto oil ratio at
the beginning of the next season.
OTHER
• Do not store gasolinefrom one season to another.
• Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your fuel system will cause problems.
•
Apply a coating of oilto the entire surface of the guide
bar and chain; wrap it in heavy paper, cloth, or plastic.
Store your unit in a well ventilated area and covered, if
possible, toprevent dust and dirtaccumulation. Do not
cover with plastic. Plastic cannot breathe and will induce condensationand eventual rustor corrosion.
•
Besure all handles and guardsare in place andare securelyfastened. Replace any damaged parts.
IMPORTANT: Never cover unitwhile engine and exhaust
areas are stillwarm.
