SAFETY RULES

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 rray result from one-handed opera

tion. A chain saw is intended for two-handed use.

• Oper^e flie chain saw only in well-ventifated outdoor

areas.

• Do not operate saw from a ladder or in a tree, unless

specifically trained to do so.

• Position all parts of your body to the left of cut and

away from the chain when the engine is running.

• Cut wood only. Do not use your saw to pry or shove away

limbs, roots, or other objects,

• Make sure the chain will not make contact with any object white starting the engine. Never try to start the saw when the guide bar is in a cut or kerf.

' Use extreme caution when cutting small size brush

and saplings. Slender material can catch the chain and be whipped toward you or pull you off balance.

' Be alert for springback when cutting a limb that is under

tension so 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

Aiplying pressure can cause you to lose control when the cut is completed.

Stop ihe engine before setting the saw down. Keep fuel and oil caps, screws, and fasteners securely

tightened.

MAINTAIN YOUR SAW IN GOOD WORKING ORDER

• Have all chain saw service performed by your Sears Service Center with the exception of the items listed in the

“Customer Responsibilities" section of this manual. For example, if improper tools are used to remove or hold the flywheel when servicing the clutch, structural damage to the flywheel can occur and cause the f^iwheel to burst.

• Make certain tiie 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 Inspect unit and repair or replace parts as necessaiy.

• Disconnect tfie spark plug before performing any

maintenance except for carburetor adjustrrwnts.

• Never modify your saw in any way. Use only SEARS '

accessories and replacement parts as recxDmrnended.

TRANSPORTING AND STORAGE

• stop the unit before transporting.

• Allow engirie to cool, cover the guide bar and chain, and

secure the unit before storing or trareporting in a trehide.

• Empty ftjel lank before storing or transporting tte unit. Use up any fuel left in the carburetor by starting the engine and letting ti^ engine run until it stops.

• Store unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric

motors or switches, furnaces, etc.

• Store unit so the chain cannot acddentally cause injury,

• Store the unit out of the reach of children.

GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.

KICKBACK WARNING;

KICKBACK CAN OCCUR WHEN THE MOV

ING CHAIN CONTACTS AN OBJECT AT THE 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 ttiat kickback can happen. With a basic

understanding of kio№ack, you can reduce the element of surprise which contributes to accidents.

• Never let the moving chain contact any object at the flp

of the guide bar. Figure 2.

• Keep ^ woiidng area free from obstructions such as

other trees, branches, roci<s, fences, stumps, etc. Figures. Eiitninate or avoid any obstruction that your chain could hit

v/htie you are cutting through a particular log or branch.

• Keep your chain sharp and property tensioned. A loose

or dull chain can increase the chance of kic^cback to occur. Follow TOnufacturer’s chain sharpening and mantenance

instructions. Check tension at regular intervals with the engine slopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning the chain.

• Begin and continue cutting at full ttirottle. If the chain is

mowng at a slower speed, there is greater chance for kfdcback to occur.

' Cut one log at a time. ' Use extreme caution when re-entering a previous cut. ’ Do not attempt plunge cuts. ' Watdi for shifting logs or other forces that could close a

cut and pinch or fall into chain.

Use the Reduced-Kickback Guide Bar and LowKtckbadc Chain speeded for your saw.

MAINTAIN CONTROL

• Keep a good, finn grip on the saw with both hands

when the engine is running and don’t let go. Rgure 4.

A firm grip can neutralize kickback and he^ you maintain

control of the saw. Keep the fingers of your left hand encirding and your left thumb under the front handlebar. Keep your right hand comptetety around the rear handle whether you are right handed or left handed. Ifeep >our left arm straight vrith the elbow locked.

• Position your left hand on the front handlebar so it is

in a sbaight line with your right hand on the rear han

dle when mafdng bucMng cuts. Figure 4. Never reverse

right and left hand positions for any tjpe of cutting.

• Stand with your weight evenly taianced on both feet

• Stand slightly to the left side of toe saw to keep your body from being in a direct line vnth toe cutting chain.

Figure 4.

• Do not overreach. You could be drawn or thrown off bal

ance and tose control of the saw.

• Do not cut above shoulder he^ht It is difflojft to main tain control of saw above shoulder height

UNDERSTANDING REACTIVE FORCES

Pindi-Kickback and Pull-In occur when tire chain is sud-

derdy stopped by being pinched, caught, or by contact ing a foreign object in the wood. This 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 tiie chain rotation. Either reaction can resuit in toss of control and pos sible serious injury.

• PindvKickbadc

- occurs when chain on lop of guide bar is suddenly

OPERATION

BEFORE STARTING ENGINE

WARNING:

GUIDE BAR AND CHAIN OIL For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. If Craftsman bar oil is hot

available, you may use a good grade SAE30 oil until you are able to obtain Craftsman brand. The oil output is automati

cally metered during operation. Your saw wifi use approxF rnately one tank of bar oil for every tank of fuel mix. Always

fill the bar oil lank when you fill the fuel tank.

GASOLINE

The two-cycle engine on this product requires a fuel mixture of regular unleaded gasoline and a quality 40:1

2-cycle engine oil (AIR-COOLED) for lubrication of the bear

ings and other moving parts. The correct fuel/oit mixture is 40:1 (see Fuel Mixture Chart).Too little oil or the irxxjtrect oil ti^e will cause poor performance and may cause the engine to overheat and seize.

Gasoline and oil must be piemixed in a clean approved fuel container. Always use fresh regular unleaded gasoline.

This engine is certified to operate on unieaded gasoline.

IMPORTANT: Experience indicates that alcohol blended

fuels called gasohol (or using ethanol or methanol) can

attract moisture, which leads to oil/gas separation and for mation of acids during storage. Actdfc 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, then run the fuel out of the carburetor and fuel lines by starling the engine

and letting it run until it stops. Use fresh fuel next season.

BE SURE TO READ THE FUEL HANDLING INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF "mis MANUAL

BEFORE YOU BEGIN.

IF YOU DO NOT UNDERSTAND THE FUEL HANDLING SECTION DO NOT ATTEMPT TO FUEL YOUR UNIT; SEEK HELP FROM

SOMEONE THAT DOES UNDERSTAND THE FUEL HANDLING SECTION OR CALL THE

CUSTOMER ASSISTANCE HOTLINE AT 1-800-235-5878.

FUEL STABIUZER Fuel stabilizer is an acceptable alternative in minimizing the

formation of fuel gum deposits during storage. Add stabiliz er to gasoline in fuel lank or storage container. Always fol low the fuel mix ratio found on the staMlizer container. Run eni^ne at least 5 minutes after adding stabilizer to allow the

stabilizer to reach the carburetor. Yju do not have to drain the fuel tank for storage if you are using fuel stabilizer.

CRAFTSMAN 40:1 2-cycte engine oil (AIR-COOLED) is specially blended with fuel stabilizers. It you do not use this Sears oil, 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 strongly recommended. This oil is specificaily blended vwth fuel stabilizers for increased fuel stability (extends fuel life up to 5 times longer) and reduced smoke.

If CRAFTSMAN 40.T 2-cyde engine oil (AIR-COOLED) is

not available, use a good quality 2-cyc!e engine oil (AIR

COOLED) that has a recommended fuel mix ratio of 40:1. IMPORTANT! Do not use:

• AUTOMOTIVE OIL

• BOAT OILS (NMMA, BIA, etc.) These oils do not have proper additives for 2-cycle

(AIR-COOLED) engines and can cause engine damage. GASOLINE AND OIL MIXTURE

MIX GASOLINE AND OIL AS FOLLOWS:

• Consult chart for correct quantities,

• Do not mix gasoline and oil directly in the unit’s fuel tank. FOR ONE GALLON:

• Ffour 3.2 ounces of high quality, 40:1 2-cycie engine oil (AIR-COOLED) into an empty, approved one gallon

gasoline rxjntainer.

• Add one gallon of regular unleaded gasoline to the gallon

container, then securely replace the cap.

• Shake the contalnerrmmentarily.

• The mixture is now ready for use. Fuel stabilizer can be added at this tforre if desired; follow mixing instructions on the label.

OPERATION

GENERAL OPERATION TIPS

• Cut wood only. Do not cut metal; plastics; masonry; non wood building materials; etc.

• Stop trie 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 pos sibility of kickback.

To get the “feel” of using your saw before you begin a major sawing operation, practice cutting a few small logs using

the following technique:

• Accelerate engine to full throttle by squeezing the throttle

trigger before entering cut.

OPERATION SAFETY

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. RESTARTTHE SAW AND CAREFULyr REENTER THE CUT. TO AVOID KICK-

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 MOV

ING CHAIN CONTACTS AN OBJECT AT THE UPPER PORTION OFTHETIP OF THE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE SAW CHAIN IN THE CUT.

CONTACT ATTHE UPPER PORTION OFTHE TIP OF THE GUIDE BAR CAN CAUSE THE CHAINTO DIG INTOTHE OBJECT AND STOP

THE CHAIN FOR AN INSTANT. TOE RESULT IS A LIGHTNING FAST, REVERSE RÉACTION

WHICH KICKS TOE GUIDE BAR UP AND BACK TOWARD THÉ 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 REACTIONS

CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY.

• Never cut with engine at partial speeds. ' Begin cutting with the saw chassis against the log. > Keep engine at full throttle during cutting procedure.

• Allow the chain to cut for you; exert only light downwrard pressure. If you force the cut, damage to №e bar, chain, or engine can result. Release the throttle trigger as soon as the cut is com pleted, 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 losing control when completing the cut, do not put pressure on the saw during the end of the cut.

Stop engine before setting unit down after operation.

AVOID REACTIVE PINCH FORCES Pinch-Kickback and Pufl-ln occur when the chain is sud

denly 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 pulfs the saw away from the operator. Either reaction can result in loss of

control and possibly serious injury.

TO AVOID PfNCH-KICKBACK:

• Be extremely aware of situations or obstructions that can cause materia! 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.

TO AVOID PULL-IN:

• Always begin cutting with the engine at full throttle and

the saw housing against wood.

• Use wedgesjpadejof plastic or wood, (never of metal) to

hold the cut open.

OPERATION

TREE FELLING

WARNING:

DETERMINE THE NATURAL FALL DIRECTION

• Wind - A tree evenly balanced will iail in the same direc tion the wind is blowing.

• Lean - Use a carpenter’s level or plumb bob to deter

mine if tree has a natural lean. A leaning tree will tend to

fell 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 influence the direction the tree will fell.

CUTTING PROCEDURE (Fig. 12) After determining the Natural Fail Direction, the tree should

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.

• Use some means to visually mark the Natural Fail

Direction.

• Mark your notch cut on the Natural Fail Direction side of

the tree approximately 18-24 inches above the ground.

• Cut top of the notch first at a 45 degree angle. Saw

through 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 wotxl.

• On the side of the tree opposite the notch cut, make the felling cut. The felling cut should be 2 inches afaoira the center point of the notch cut. Before the felling cut is complete, use wedges to open the cut when necessary

to control the direction of the fell. Use wood or plastic wedges, but never steel or iron, to avoid kickback and

chain damage.

» Cracking sounds, widening of the felling cut, movement

in the upper branches are all signs that the tree is ready

to fell.

' As tree begins to fell, turn off saw, and move quickly

away from direction of fall.

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 (HAMMER) TO FORCE THE FELLING CUT OPEN. THE WEDGE WILL HOLD THE FELLING CUT OPEN ALLOWING YOU TO REMOVE THE SAW. KEEP EVERYONE AWAY FROM THE TREE IN ALL DIRECTIONS.

•

If your chain saw binds in the felling cut, you have three

options:

• If the wrong direction of fail is acceptable, carefully remo\ra the felling wedge.Cut deeper in the notch side of

the tree untH tree starts to fall.

• If the wrong direction of fall is not acceptabie, 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 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 to stand on the up-hill side when cutting on 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.

OPERATION SAFETY

DONT PUTYOURSELF INTHESE POSITIONS

Check the wind -

Don’t cut down wind

WARNING:

* Lodk 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.

* Be extremely cautious with partially fallen trees that may

be poorly supported. When a free doesn't fall completely, set the saw aside and puli down the tree with a cable wirtch, block and tackle, or tractor. To avoid Injury, do not

cut down a partially fallen tree with your saw.

DO NOT CUT:

- NEAR ELECTRICAL WIRES OR

BUILDINGS.

- IF YOU DO NOT KNOW THE DIRECTION

OF TREE FALL.

- AT NIGHT.

- DURING BAD WEATHER - RAIN, SNOW,

STRONG WIND, ETC.

Check the lean -

Don't cut on down side Don't cut on weighted side

OPERATiON

BUCKING

Bucking is cutting a fallen tree to the desired log si2e.

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 underside of the log with the

top of the saw chassis against the log; exert light pres sure 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.

Undercut

Saw Chassis

F^ure 13

BUCKING ON THE GROUND (Fig. 14)

• Overcut with a 1/3 diameter cut.

• Roll log over and finish with an overcut.

BUCKING USING A SUPPORT (Fig. 15 & 16)

Another log or a stand, such as a sawhorse, may be used as supports when bucking.

• Area A - Undercut 1/3 of the way through the log.

- Finish with an overcut.

• Area B - Overcut 1/3 of the way through the log.

- Finish with an undercut.

BUCKING SAFETY

WARNING:

Stay on uphill side of tree when cutting.

DO NOT STAND ON THE LOG BEING CUT, ANY PORTION CAN ROLL CAUSING LOSS

OF FOOTING AND CONTROL, NEVER TURN THE SAW UPSIDE DOWN TO

UNDERCUT. THE SAW CANNOT BE CON

TROLLED IN THIS POSITION.

BUCKING TIPS

• Cut only one log at a time.

• Cut shattered wood very carefully. Sharp pieces of wood

OiUld be flung toward the operator.

• Use a sawhorse to cut small logs. Never allow another persott to hold the log while cutting and never hold the log with your teg or foot.

• Do not cut in an area where logs, limbs, and roots are

tangled such as in'a blown down area. Drag the logs Into a clear area before cutting by pulling out exposed and cleared logs first

• Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the fog.

PRUNING AND UMBING

Pruning is removing branches from a standing tree.

Limbing is removing branches from a felfed tree. UMBING (Fig. 17)

• Start at base of the felled tree and work toward the top.

• Leave the larger limbs underneath the felled tree to

support the tree as you work.

PRUNING {Fig. 18)

Small branches - smaller than width of guide bar. Large branches - larger than wridth of guide bar.

• Remow small limbs with one cut.

• Remove lar^r, supporting branches with the 1/3 - 2/3

cutting techniques described in the bucking section.

PRUNfNG PROCEDURE

• Cut 1 - Undercut 1/3 of the way through the limb near

the trunk of the tree.

• Cut 2 - Finish with an overcut farther out from the trunk

untii the limb falls. Keep out of the way of the falling littfa.

• Pruning Cut - Cut the limb stump flush at the edge of

the collar.

PRUNING AND LIMBING TIPS

• Work slowly, keeping both hands firmly gripped on the

saw. Maintain secure footing and balance.

• Keep a clear work area. Frequently clear branches out of the way to avoid topping over faem.

• Leave the larger limbs underneath the felled tree to sup

port the tree as you work.

• Start at the base of the felled tree and work toward the

top.

• Keep the tree between you and the chain. Cut from the

side of frie tree opposite the branch you are cutting.

• Limit pruning to limbs shoulder height or below.

• Keep out of the way of the falling limb.

OPERATION SAFETY

PRUNING AND UMBING SAFETY

WARNING:

NEVER CLIMB INTO A TREE TO LIMB OR PRUNE UNLESS SPECIRCALLY TRAINED TO DO SO. 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.

BE ALERT FOR AND GUARD AGAINST KICKBACK. DO NOT ALLOW THE MOVING CHAIN TO CONTACT ANY OTHER BRANCH

ES OR OBJECTS AT THE NOSE OF THE GUIDE BAR WHEN LIMBING OR PRUNING. ALLOWING SUCH CONTACT CAN RESULT IN SERIOUS INJURY.

DO NOT CUT IF BRANCHES ARE HIGHER

THAN YOUR SHOULDER. GET A PROFES SIONAL TO DO THE JOB.THIS MAY RESULT IN SERIOUS INJURY. ;

Watch out for springpoles. Use extreme caution when cutting small giSe lirfibs. Slender material may catch the saw chain and be whipped toward you or pull you off

balance. Be afert for springback. Watch out for branches that are bent Of under pressure as you are cutting to avoid being struck by the branch or the saw when the tension in the wood fibers is released.

CARBURETOR ADJUSTMENTS

Carburetor adjustment is critical and if done improper* * ly can permanently damage the engine as welf as the

carburetor. Please read all instructions and consult the Trouble Shooting section of this manual before begin* nfng this process. If the engine does not operate according to these instructions after repeating the

adjusting steps, do not use the unit. For further assis

tance, please call our customer assistance hotline at 1-800-235*5878.

WARNING:

THE CHAIN WILL BE MOVING DURING MOST OF THIS PROCEDURE. VTCAR YOUR PROTECTIVE EQUIPMENT AND OBSERVE

ALL SAFETY PRECAUTIONS.

IN “LOW SPEED MIXTURE ADJUSTMENT,” RECHECK IDLE SPEED AFTER EACH ADJUSTMENT. THE CHAIN MUST NOT MOVE AT IDLE SPEED.

If engine does not start, if 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 significantly higher altitudes or if you notice any of the following conditions:

CARBURETOR PRESETS (Fig, 49) If your engine will not start due to suspected improper car

buretor adjustment, the following presete may be required. Jf used, it is recommended that all steps within the adjust ment procedure be completed in order to assure a properly set carburetor. If presets are not needed, proceed to sec

tion "Idle Speed Adjustment."

When making adjustments, be careful not to force the plas tic iimifer caps beyond the stops or damage will occur.

Very small adjustments can affect engine performance. It is important to make slight adjustments and test perfomranc^

before proceeding. Each adjustment'should be no mote than 1/16 of a turn,

• Turn both of the mixture adjustments clockwise until they stop. Do not overtighten as damage to the needles will occur,

• Turn both mixture adjustments counterclockwise one full

turn.

• Turn the idle speed adjustment clockwise until it stops.

Now turn counterclockwise 4-1/2 turns.

• It 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 “Adjusting Procedure."

• Chain moves when the engine runs at idle speed. See

“Idle Speed Adjustment.”

• Saw wiil not idle. See “Idle Speed Adjustment" and “Low

Speed Mixture Adjustment."

• Engine dies or hesitates when it should accelerate. See

“Acceieration Adjustment."

• Loss of cutting power which is not corrected by air filter

cleaning. See “High Speed Mixture Adjustment."

NOTE - There are three adjustments on the carburetor.

• The Idle Speed Adjustment is mariced with the letter “T.”

• The two remaining adjustments on the carburetor are the mixture adjustments. One is marked T” for low speed,

and the other “H” for high speed.

-25-

Page 26

SERVICE AND ADJUSTMENTS

ADJUSTING PROCEDURE IDLE SPEED ADJUSTMENT “Г’

• Allow the warm engine to idle.

• Adjust the Idle Speed until the engine continues to run

without stalling and without the chain moving.

— Turn clockwise to increase engine speed if enaine

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 Adjustment slowly dock-

wise until the RPM starts to drop. Note the position.

• Turn the Low Speed Mixture Adjustment slowly counter

clockwise 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.

HIGH SPEED MIXTURE ADJUSTMENT“H” IMPORTANT: DO NOT OPERATE ENGINE AT FULL THROTTLE FOR PROLONGED PERIODS WHILE MAK ING HIGH SPEED ADJUSTMENTS AS DAMAGE TO THE ENGINE CAN OCCUR.

• Make a test cut.

• Based on performance of the saw while cutting, adjust

the high speed mixture in 1/16 turn increments as fol

lows:

- Clockwise if saw loses power in the cut. Do not adjust

for best power by sound or speed, but judge by how well the saw performs in the cut.

- Counterclockwise if 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 adjustments until the saw perfor mance is acceptable while cutting.

• After completing adjustments, check for acceleration.

ACCELERATION CHECK

• If the engine dies or hesitates instead of accelerating, turn the Low Speed Mixture Adjustment 1/16 of a turn at a time counterclockwise until you have smooth accelera tion.

• Check the idle speed for stability and no chain move

ment. Adjust as necessary.

• Recheck for smooth acceleration and stable idle. Repeat

process as necessary for acceptable performance.

STORAGE

Immediately prepare your unit for storage at the end of the season or if it will not be used for 30 days or more.

WARNING: ALLOW THE ENGINE TO COOL, AND

SECURE THE UNIT BEFORE STORING OR TRANSPORTING IN A VEHICLE.

STORE UNIT AND FUEL IN AN AREA WHERE FUEL VAPORS CANNOT REACH SPARKS OR OPEN FLAMES FROM WATER HEATERS, ELECTRIC MOTORS OR SWITCH

ES, FURNACES, ETC. STORE UNIT WITH ALL GUARDS IN PLACE.

POSITION SO THAT ANY SHARP OBJECT CANNOT ACCIDENTALLY CAUSE INJURY

TO PASSERS BY. STORE THE UNIT OUT OF THE REACH OF

CHILDREN.

GAS CHAIN SAW STORAGE INSTRUCTIONS

If your chain is to be stored for a period of time, clean if thoroughly prior to storage. Remove any dirt, sawdust, leaves, oil, grease, etc. Store in a dean dry area.

• Clean the entire unit.

• Clean air filter. Refer to “Customer Responsibilities."

• Inspect the bar clamp area and clean any dirt, sawdust, grass, or debris that has collected. Inspect the guide bar

and chain: replace a guide bar that is bent, warped, cracked, broken, or damaged in any other way. Replace a damaged or worn chain.

• Lightly oil external metal surfaces to prevent rust from

forming.

CAUTION: Wear protective gloves when

handling chain. The chain is sharp and can cut you even when it is not moving.

IMPORTANT: It is important to prevent gum deposits from

forming in essential fuel system parts such as the carbure tor, fuel filter, fuel hose or tank during storage. Also, expe

rience indicates that alcohol blended fuels, those that use ethanot or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic gas which will damage your engine. To avoid engine problerr®, the fuel system should be 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 sta bilizer to the gasoline in the fuel tank or fuel storage con

tainer. Always follow the mix instructions found on stabilizer containers. Run engine at least S ntinutes after adding sta bilizer to allow the stabilizer to reach ttie 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.

INTERNAL ENGINE

• Remove spark plug and pour 1 teaspoon of 40:1 2-cycle

engine oil (AIR-COOLED) through the spark plug open ing. Slowly puli the starter rope 8 to 10 times to distribute oil to inner engine surfaces.

• Replace spark plug with a new one of the recommended

type and heat range. Refer to ‘Product Specifications.”

• Clean air fitter. Refer to “Customer Responsibilities."

• Re-install all covers and hatbvrare removed for access: tighten all screws and fasteners. _

• Chedc entire unit for loose screws, nuts, and bolts.

Replace any damaged, broken, or worn parts.

• Lightly oil external metal surface to prevent rust from

forming.

. Use fresh fuel having the proper gasoline to oii ratio at

the beginning of the next season.

• Apply a coating of oil to the entire surface of the guide

bar and chain; wrap it in heavy paper or cloth.

• Be sure ail handles and guards are In place and are

securely fastened. Replace any damaged parts.

FUEL SYSTEM Never use engine or caitiuretor cleaner products in the fuel tank or permanent damage may occur to fuel system com ponents. Follow these instructions:

• Drain the fuel from the unit into an approved fuel con

tainer.

• Drain the fuel lines and caiburetor by starting the engine

and letting it run until it stops.

• Allow the engine to cool before storage.

OTHER

• Do not store gasoline from 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.

• Store your unit in’ a well ventilated area and covered, if possible, to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will induce condensation and eventual rust or corrosion.
