• Wear protective gear. Always use steal-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 pads.

• Keep all parts of your body away from the chain when the engine is

running.

• Keep children, bystanders, and ani-

mals at least 30 feet (10 meters)

away from the work area when start-

ing 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 especially if you are felling a tree, a

retreat path.

OPERATE YOUR SAW SAFELY

• Do not operate with one hand. Seri- ous injury to the operator, helpers, or

bystanders may result-from one- handed operation. A chain saw is in-

tended for two-hended 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, es- pecially at the end of the cut. Doing

so 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, improperlyadjusted, or not completelyend securely assembled.

Always replace bar, chain, hand guard, chain brake, orother parts im- mediately ifthey becomedamaged,

broken,or are otherwise removed.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service per- formed by a qualified service dealer

except the items listed in the MAINTE- NANCEsection 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 orfuel mixture.

• Keep caps and fasteners securely

t!ghtened.

• Nonconformingreplacement compo-

nents or the removalof safetydevices may cause damage to the unit and

possibleinjury to the operator or by- standers. Use only Craftsman acces-

sories and replacement parts as rec- ommended. Never modifyyour saw.

• Maintain chain saw with care.

• Keep unit sharp and clean for better

and safer performance.

• Follow instructionsfor lubricating and

changing accessories.

• Check for damaged parts. Before fur-

ther use of the chainsaw, a guard or other part that is damaged shouldbe

carefullycheckedto determine that it

willoperate propedy and perform its

intendedfunction. Check foralignment

of movingparts, bindingof moving

parts,breakage of parts, mountingand any other conditionsthat may affectits

operation.A guard or other partthat is

damaged shouldbe properlyrepaired

or replaced bya Sears Service Center

unlessotherwiseindicatedelsewhere in the instructionmanual.

• When not in use, chain saws should be storedin 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.

• Eliminateall sources of sparks or flame in areas where fuel is mixed or

poured.

• Mix and pour fuel inan outdoorarea 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.

• Turn the engine off and letsaw 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 va- pors 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.

_ ._j_q Kickback Path

Avoid

Clear The Working Area

WARNING: Avoid kickback which

can result in serious injury. Kickback is the backward, upward or sudden for-

ward 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 diginto 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 di-

rection 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 bot- tom of the guide bar and the saw chain is suddenly stopped. This sudden stopping pulls the saw for-

ward and away. from the operator and could easdy cause the opera-

tor to lose control of the saw.

REDUCE THE CHANCE OF KICKBACK

• Recognize that kickback can happen.

With a basic understanding of kick- back, you can reduce the element of

surprise which contributes to acci-

dents.

• Never let the moving chain contact

any object at the tip of the guide bar.

• Keep working area free from obstruc-

tions 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. Fol- low manufacturer'schainsharpening

and maintenance instructions.Check

tension at regular intervals, butnever with engine running.Make surechain brake nuts are securelytightened.

• Begin and continuecuttingat full speed, ifthe chain is movingat a

slower speed, there is greater chance

of kickbackoccurring.

• Use extreme caution when reentering a cut.

i Do not attemptcuts startingwith the

Watch for shiftinglogsor other forces that could close a cut and pinchor fall

into chain.

• Use the specif'_d Reduced-Kickback Guide Bar and Low-KickbackChain.

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 cutmore than one logat a

time.

• Do not twistsaw as bar is withdrawn

froman undercutwhen bucking.

Avoid Pull-in:

• Always begin cuttingwith the engine at ful/speed and the saw housing

against wood.

• Use wedges made of plastic or wood. Never use metal to hold the cut open.

MAINTAIN CONTROL

• A good, firm grip on the saw with both hands will help you maintain control.

Don't let go. Grip the rear handle with

your right hand whether you are right

or left handed. Wrap the fingers of

/rOUrleft hand over and around the

ont handlebar, and your left thumb

under the front handlebar. Keep your left arm straight with the elbow locked.

• Position your left hand on the front handlebar so it is in a straight line with your right hand on the rear handle

when making bucking cots. Stand

slightly to the left side of the saw to

keep your body from being in a direct line with the cuttingchain.

• Stand with your weight evenlybal-

KICKBACK SAFETY FEATURES

_lL WARNING: The following features are included on your saw to help reduce

hazard of kickback; however, such fea- tures will not totally eliminate this danger.

Do not rely only on safety devices. Fol-

low all safety rules to help avoid kick- back 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 dan- ger 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.

CHAIN BRAKE

• Chain Brake: designed to stop the

chain in the event of kickback.

,d_WARNING: WE DONOTREP- RESENTAND YOU SHOULD NOT AS-

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 rotat-

ing chain back and up toward the op- erator. Kickback can be caused by al-

lowing 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 re-

duce 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 au- thorized Sears Service Center. Take

your unit to the place of purchase or to

your nearest Sears Service Center.

• 13p 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.

SAFETY NOTICE: Exposure to vibra- tions through prolonged use of gasoline

powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to

circulation disorders or abnormal swell- ing. Prolonged use in cold weather has

been linked to blood vessel damage in otherwise healthy people. If symptoms

occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or

joints, discontinue the use of this tool and seek medical attention. P_nanti-vi-

bration system does not guaranteethe avoidance of these problems. Users who operate power tools on a continual

and regular basis must closely monitor

their physical condition and the condition of this tool.

CHAIN BRAKE: if this saw is to be used for commercial logging, a chain

brake is required and shall not be re- moved or otherwise disabled to comply with Federal OSHA Regulations for

Commercial Logging. SPARK ARRESTING SCREEN: Your

saw is equipped with a temperature lim- iting muffler and spark arresting screen

which meets the requirements of Califor- nia Codes 4442 and 4443. All U.S. for-

est land and the states of California, Ida- ho, Maine, Minnesota, New Jersey, Oregon, and Washington requireby law

that many internalcombustionengines be equipped with a spark arresting

screen, if you operate a chainsaw in a state or locale where such regulations exist, you are legallyresponsiblefor

maintainingthe operatingconditionof

these parts. Failure to do so is a viola- tion of the law. Refer to Customer Re-

sponsibilitieschartin the MAINTENANCE section.

should check your chain tension fre- quently. See CHAIN TENSION under the

SERVICE AND ADJUSTMENTS section.

_IL WARNING: Muffler.is very hot

during and after use. Do not touch the muffler or allow combustible matedal

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, tf 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. In- cluded with this saw is a 3.2 ounce

container of Craftsman brand synthetic oil. Pour the entire contents of this

container into 1 gallon of gasoline to achieve the proper fuel mixture.

DO NOT USE automotive oil 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 isthoroughly mixed. Al-

ways read and follow the safety rules relating to fuel before fueling your unit. IMPORTANT Experience indicatesthat alcohol blended fuels (called gasoholor using ethanol or methanol) can attract mois-

ture which leads to separationand formationof acids dudngstorage. Acidic gas can damage the fuel system of an

engine while in storage. To avoidengine problems, the fuelsystem shouldbe emptied before storagefor 30 days or longer. Drain the gas tank, startthe en-

gine and let itrun untilthe fuellines and carburetor are empty.Use freshfuel

next season. See STORAGEinstructions

for additionalinformation.

Never use engine or carburetor clean- er products in the fuel tank or perma- nent damage may occur.

See the STORAGE section for addition- al information.

CHAIN BRAKE Ensure chain brake is disengaged by pulling the front hand guard back to-

ward the front handle as far as pos-

sible. The chain brake must be disen-

gaged before cutting with the saw.

Z'L __ _____

dtSWARNING: 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 con- tact with the muffler. A hot muffler can

cause serious burns. STOPPING YOUR ENGINE

• Move ON/STOP switch to the STOP position.

STARTING POSITION

• To start the engine, hold the saw firmly on the ground as illustrated.

OPERATING TIPS

• Check chain tension before first use

and after 1 minute of operation. See CHAINTENSION in the MAINTENANCE

section.

• Cut wood only. Do not cut metal, plas- tics, masonry, non-wood buildingma-

terials, etc.

• Stop the saw ifthe chain strikes a foreign object. Inspect the saw and

repair parts as necessary.

• Keep the chain out of _lirt and sand. Even a small amount of dirt will

quickly dull a chain and increase the possibility of kickback.

• Practice cuttinga few small logs using

the followingsteps. This will help you

get the "feel" of usingyour saw before

you begin a major sawingoperation.

• Squeeze the throttle trigger and al-

low 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 lightdownward pressure.

• Release the throttle trigger as soon as the cut is completed, allowing

the engine to idle. If you run the

saw at fullthrottle without a cutting load, unnecessary wear can occur

to the chain, bar and engine. It is

recommended that the engine not be operated for longer than

30 seconds at full throttle.

• TOavoid losing control when cut is complete, do not put pressure on

saw at end of cut.

• Stop engine before settingsaw down. TREE FELLING TECHNIQUES

WARNING: Check for broken or

dead branches which can fall while cutting causing sedous 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 a tree makes contact with any utility line, the utility company should be notified immediately.

• Carefully plan yoursawing 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 ina particular

direction. These conditions include:

• The wind direction and speed.

• The lean of the tree. The lean ofa

tree might not beapparent due to

uneven or sloping terrain. Use a plumb or level to determine the di- rection of tree lean.

• Weight and branches on one side.

• Surrounding trees and obstacles.

• Look for decay and rot. If the trunk is rotted, itcan snap and fall toward the

operator.

• Make sure there is enough roomfor

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.

FELUNG LARGE TREES

(6 inches in diameter or-larger)

The notch method is used to fell large trees. A notch is cut onlhe side of the

tree in the desired direction of fall. After

a felling cut is made on the opposite side oftree, the tree will tend to fall in

the direction of the notch.

NOTE: If 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 dL!llingofthe chain. NOTCH CUT AND FELLING TREE

• Make notch cut by cutting the top of the notch first. Cut through 1/3 of the

diameter of the tree. Next complete the notch by cutting the bottom. See

illustration. Once the notch is cut, re- move the wedge of wood from tree.

.Lift...

Se_°_._ '''_'/ / t ____..._,nge

• 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

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.

Hinge holds tree on stump and helps

control fall

Opening of felling cut

Closir of

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.

• Be alert to signs that the tree is ready

to fall: cracking sounds, widening of the felling cut, or movement in the up-

per 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 cutdown 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, blockand tackle,

or tractor.

CU'I'FING A FALLEN TREE (BUCKING)

Bucking is the term used for cutting a

fallen tree to the desired log size.

_, WARNING: Do not stand on the

log being cut. Any portioncan roll causing loss of footingand 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 ofwood couldbe 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 rootsare tangled. Drag logs into a cleararea beforecuttingthem

by pullingout exposedand cleared

logsfirst.

BUCKING TECHNIQUES

_k 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. Re- start saw and carefully reenter the cut.

Do not use a metal wedge. Do not at- tempt 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.

_ttlng Und_c_l_ng

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 willtend to push back toward you.

_IbWARNING: Never turn 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

_WARNING: Be alert for and guard

against kickback. Do not allow the mov- ing 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.

First cut on compression side of log

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 pinch- ing. See illustration above for cut-

ting 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. (Re-

fer 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.

Using a log for support

1s! Cut

WARNING: Never climb into a

tree to limb or prune. Do not stand on

ladders, platforms, a log, or in any po-

sition 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 cau- tion 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.

LIMBING

• Limb a tree only after it is cut down.

• 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.

• Remove larger branches with the

cutting techniques described in

BUCKING WITHOUT ASUPPORT.

• Always use an overcut to cut small and freely hanging limbs. Undercut-

ting could cause limbs to fall and

pinch the saw.

PRUNING

• Next make the second cut an over-

cut all the way through the limb.

• Finish the pruning operation by using an overcut so that the stump of the limb protrudes 1 to 2 inches from the

trunk of the tree.

Second cut

WARNING: Limit pruning to limbs

shoulder height or below. Do not cut if

Rrst cut 1/3 of way

branches are higher than yourshoul- der. Get a professional to do the job.

• Make your first cut 1/3 of the way

through the bottom of the limb. This cut will make the limb sag so that it

Third cut 1to 2 inches from trunk of tree

falls easily on the second cut.

_WARNING: If the saw is operated

with a loose chain, the chain could jump off the guide bar and result in se-

rious injury. CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder

and cuts slowly. See CHAIN SHARP- ENING in the SERVICE AND ADJUST-

MENTS section.

CHECKGUIDEBAR Conditionswhichrequireguidebar

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.
