A rot, WARNING: Always disconnect

spark plug wire when making repairs except for carburetor adjustments. Be- cause a chain saw is a high-speed

woodcutting tool, special precautions must be observed to reduce risk of ac-

cidents. Careless or improper use of this tool can cause serious injury.

PLAN AHEAD

• Restrict tile use of your saw to adult

users who understand and can fol- low the safety rules, precautions,

and operating instructions found in this manual.

Snug _ tlP'°l'_ Protection Fitting _ Heavy Duty

Clothing Gloves

Safety Safety Chaps Shoes

• Wear protective gear. Always use

steel-toed safety footwear with non- slip soles; snug-fitting clothing;

heavy-duty, non-slip gloves; eye pro-

tection 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. Regular 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 parts.

• 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 work area when starting or using

saw.

• Do not handle or operate a chain saw

when you are fatigued, ill, or upset, 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 operating.

• 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-handed 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 at the end of the cut. Applying pressure

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 and chain proj-

ecting behind you; guide bar prefer- ably covered with a scabbard.

• Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Always replace bar, chain, hand

guard, chain brake, or other parts im- mediately if they become damaged,

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-

NANCE section of this manual.

• Make certain the saw chain stops moving when the throttle trigger is

released. For correction, refer to CARBURETOR ADJUSTMENTS.

• Keep the handles dry, clean, and free from oil or fuel mixture.

• Keep caps and fasteners securely tightened.

• Nonconforming replacement compo- nents or the removal of safety devices may cause damage to the unit and

possible injury to the operator or by- standers. Use only Craftsman acces- sories and replacement parts as rec- ommended. Never modify your saw.

• Maintain chain saw with care.

• Keep unit sharp and clean for better and safer performance.

• Follow instructions for lubricating and changing accessories.

• Check for damaged parts. Before fur- ther use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its

intended function. Check for alignment

of moving parts, binding of moving

parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by a Sears Service Center

unless otherwise indicated elsewhere

in the instruction manual.

• When not in use, chain saws should be stored in a dry, high or locked-up place out of the reach of children.

• When storing saw, use a scabbard or

carrying case.

HANDLE FUEL WITH CAUTION

• Do not smoke while handling fuel or

while operating the saw.

• Eliminate all sources of sparks or

flame in the areas where fuel is

mixed or poured.

• Mix and pour fuel in an outdoor area

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 let saw cool in a non-combustible area, not on

dry leaves, straw, paper, etc. Slowly

remove fuel cap and refuel unit.

• Store the unit and fuel in a cool, dry

well ventilated space where fuel 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.

'x_ _ Kickback Path

, J,

Clear The Working Area

411 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 dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator.

• Pinch-Kickback can occur when the the wood closes in and pinches the

moving saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. This sud- den stopping of the chain results in a

reversal of the chain force used to cut wood and causes the saw to

move in the opposite direction of the chain rotation. The saw is driven

straight back toward the operator.

• Pull-In can occur when the moving chain contacts a foreign object in the wood in the cut along the bottom of

the guide bar and the saw chain is suddenly stopped. This sudden stop- ping pulls the saw forward and away from the operator and could easily cause the operator to lose control of

the saw.

REDUCE THE CHANCE OF KICKBACK

• Recognize that kickback can happen. With a basic understanding of 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.

Follow manufacturer's chain sharp- ening and maintenance instructions. Check tension at regular intervals,

but never with engine running. Make sure bar clamp nuts are securely tightened.

• Begin and continue cutting at full speed. If the chain is moving at a

slower speed, there is greater chance of kickback occurring.

• Use extreme caution when re-enter-

ing a cut.

• Do not attempt cuts starting with the tip of the bar (plunge cuts).

• Watch for shifting logs or other forces that could close a cut and pinch or

fall into chain.

• Use the specified Reduced-Kickback Guide Bar and Low Kickback Chain.

Avoid Pinch-Kickback:

• Be extremely aware of situations or obstructions that can cause material

to pinch the top of or otherwise stop the chain.

• Do not cut more than one log at a time.

• Do not twist the saw as the bar is withdrawn from an undercut when

bucking.

Avoid Pull-In:

• Always begin cutting with the engine at full speed and the saw housing against wood.

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

cut open.

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 your left hand over and

around the front handlebar, and your

left thumb under the front handlebar.

Keep your left arm straight with the elbow locked.

KICKBACKSAFETY FEATURES

WARNING: The following fea-

tures are included on your saw to help reduce hazard of kickback; however,

such features will not totally eliminate this danger. Do not rely only on safety devices. Follow all safety rules to help

avoid kickback and other forces which can result in serious injury.

• Front Hand Guard: designed to re- duce the chance of your left hand

contacting the chain if your hand slips off the front handlebar.

• Position of front and rear handlebars, designed with distance between

handles and "in-line" with each other. The spread and "in-line" position of

the hands provided by this design work together to give balance and

resistance in controlling the pivot of the saw back toward the operator if

kickback occurs.

• Reduced-Kickback Guide Bar, de- signed with a small radius tip which

reduces the size of the kickback danger zone on the bar tip. This type bar has been demonstrated to signif-

icantly reduce the number and seri- ousness of kickbacks when tested in

accordance with ANSI B175.1.

Ai_ WARNING: WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS- SUME THATTHE 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 orto

your nearest Sears Service Center.

• Tip contact in some cases may cause a lightning fast reverse REACTION,

kicking guide bar up and back toward

operator.

• Pinching the saw chain along the top of the guide bar may push the guide

bar rapidly back toward the operator.

• Either of these reactions may cause you to lose control of the saw which

could result in serious injury. Do not

rely exclusively upon safety devices built into your saw.

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 require by law

that many internal combustion engines

be equipped with a spark arresting

screen. Ifyou operate a chain saw in a

state or locale where such regulations exist, you are legally responsible for

maintaining the operating condition of

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

sponsibilities chart in the MAINTENANCE

section. STANDARDS: This chain saw is listed

z't dt_ WARNING: Be sure to read the

fuel handling information in the safety rules section of this manual before you

begin. If 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 bar oil tank when you

fill the fuel tank.

FUELING ENGINE

4t_ WARNING: Remove fuel cap slowly when refueling. This engine is certified to operate on un- leaded gasoline. Before operation, gaso-

line must be mixed with a good quality synthetic 2-cycle air-cooled engine oil. We recommend Craftsman brand syn- thetic oil. Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mix- ing 3.2 ounces of oil with 1 gallon of un- leaded gasoline. Included with this saw

is a 3.2 ounce container of 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 isadded to the gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Al- ways read and follow the safety rules

relating to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract mois- ture which leads to 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 sys- tem should be emptied before storage

for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty.

Use fresh fuel next season. See STOR- AGE instructions for additional informa-

tion. Never use engine or carburetor

cleaner products in the fuel tank or per-

manent damage may occur.

See the STORAGE section for additional

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. Aid, WARNING: 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

BLESHOOTINGTABLE or call 1-800-235-5878.

CHAIN BRAKE

WARNING: If the brake band is

worn too thin it may break when the

chain brake is triggered. With a broken brake band, the chain brake will not stop

the chain. The chain brake must be re-

placed if any part is worn to less than 1/32" thick. Repairs on a chain brake

should be made by your Sears Service

Center. Take your unit to the place of purchase or to the nearest Sears Ser-

vice Center.

• This saw is equipped with a chain brake. The brake is designed to stop

the chain if kickback occurs.

• The inertia-activated chain brake is

activated if the front hand guard is

pushed forward, either manually (by hand) or automatically (by sudden movement).

• If the brake is already activated, it is

disengaged by pulling the front hand guard back toward the front handle as far as possible.

• When cutting with the saw, the chain brake must be disengaged.

hand and the front handle with your left hand. Hold the chain saw approxi- mately 14" (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the tip of the

guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate. OPERATING TIPS

• Check chain tension before first use

and after 1 minute of operation. See CHAIN TENSION in the MAINTENANCE section.

• Cut wood only. Do not cut metal,

plastics, masonry, non-wood building materials, etc.

• Stop the saw if the chain strikes a

foreign object. Inspect the saw and repair parts as necessary.

• Keep the chain out of dirt and sand.

Even a small amount of dirt will quickly dull a chain and increase the

possibility of kickback.

• Practice cutting a few small logs using

the following steps. This will help you get the "feel" of using your saw before you begin a major sawing operation.

• Squeeze the throttle trigger and 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 light downward pressure.

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

the engine to idle. If you run the

saw at full throttle without a cutting load, unnecessary wear can occur.

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

saw at end of cut.

• Stop the engine before setting the saw down.

TREE FELLING TECHNIQUES _WARNING: Check for broken or

dead branches which can fall while cutting causing serious injury. Do not

cut near buildings or electrical wires if

you do not know the direction of tree fall, nor cut at night since you will not

be able to see well, nor during bad

weather such as rain, snow, or strong winds, etc.

• Carefully plan your sawing operation

in advance.

• Clear the work area. You need a clear area all around the tree so you

can have secure footing.

• The chain saw operator should keep on the uphill side of the terrain as the

tree is likely to roll or slide downhill after it is felled.

• Study the natural conditions that can cause the tree to fall in a particular

direction, such conditions include:

• The wind direction and speed.

• The lean of the tree. The lean of a tree might not be apparent 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, it can snap and fall toward the

operator.

• Make sure there is enough room for

the tree to fall. Maintain a distance of 2-1/2 tree lengths from the nearest

person or other objects. Engine noise can drown out a warning call.

• Remove dirt, stones, loose bark, nails, staples, and wire from the tree

where cuts are to be made.

FELLING LARGE TREES

(6 inches in diameter or larger)

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

tree in the desired direction of fall. After a felling cut is made on the opposite

side of tree, the tree should fall in the direction of the notch.

NOTE: If the 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 dulling of the 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 the

tree.

Felling cut here

Firstcut

Secondcut_"!_ t

• 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 feINng

Closing of notch

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 of signs that the tree is ready to fall: cracking sounds, widen- ing of the felling cut, or movement in

the upper branches.

• As tree starts to fall, stop saw, put it

down, and get away quickly on your

planned retreat path.

• DO NOT use your saw to cut down a partially fallen tree. Be extremely

cautious with partially fallen trees that may be poorly supported. When a tree doesn't fall completely, set the

saw aside and pull down the tree with a cable winch, block and tackle,

or tractor.

CUTTING A FALLEN TREE (BUCKING)

Bucking is tile term used for cutting a

fallen tree to the desired log size. '_,WARNING: Do not stand on the

log being cut. Any portion can roll causing loss of footing and control. Do not stand downhill of the log being cut.

IMPORTANT POINTS

• Cut only one log at a time.

• Cut shattered wood very carefully;

sharp pieces of wood could be flung toward operator.

• Use a sawhorse to cut small logs. Never allow another person to hold

the log while cutting and never hold the log with your leg or foot.

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

the logs into a clear area before cut- ting them by pulling out exposed and cleared logs first.

BUCKING TECHNIQUES

_,WARNING: If saw becomes

pinched or hung in a log, don't try to

force it out. You can lose control of the

saw resulting in injury and/or damage

to the saw. Stop the saw, drive a wedge of plastic or wood into the cut

until the saw can be removed easily. Restart the saw and carefully reenter

the cut. Do not use a metal wedge. Do

not attempt to restart your saw when it is pinched or hung in a log.

Use a wedge to remove pinched saw

Turn saw OFF and use a plastic or wooden wedge to force cut open.

Overcutting Undercutting

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 will tend to push back toward you.

,Lot

4t_ WARNING: 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.

BUCKING WITHOUT A SUPPORT

• Overcut through 1/3of 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 illustrations 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. (Refer to the illustrations for your first and second cut)

• Your first cut should extend 1/3of the diameter of the log.

• Finish with your second cut.

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.

,_ 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 on them.

• Removelargerbrancheswiththe cuttingtechniquesdescribedin BUCKINGWITHOUTASUPPORT.

• Make your first cut 1/3of the way through the bottom of the limb. This cut will make the limb sag so that it falls easily on the second cut.

• 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.

CHECK CHAIN TENSION _L, WARNING: Wear protective

gloves when handling chain. The chain is sharp and can cut you even

when it is not moving. Chain tension is very important. Chains stretch during use. This is es- pecially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

1. Use the screwdriver end of the chain adjustment tool (bar tool) to

move chain around guide bar to ensure kinks do not exist. The

chain should rotate freely.
