WARNING: Always disconnect

spark plug wire when making repairs ex- cept for carburetor adjustments. Be-

cause a chain saw is a high-speed wood-cutting tool, special precautions

must be observed to reduce the risk of accidents. 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 safety rules, precautions, and

operating instructions found in this manual.

• Wear protective gear. Always use steel-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 parts.

• Keep all parts of your body away from

the chain when the engine is running.

• Keep children, bystanders, and ani- mals a minimum of 30 feet (10 me-

ters) away from the work area when starting 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,

if you are felling trees, a planned re-

treat path.

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 may result from

one-handed operation. A chain saw is intended 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 & chain project- ing behind you; guide bar preferably

covered with a scabbard.

• Do not operate a chain saw that is damaged, improperly adjusted, or

not completely and securely as- sembled. Always replace bar, chain,

hand guard, or chain brake immedi- ately if it becomes damaged, broken

or is otherwise removed.

MAINTAIN YOUR SAW IN GOOD WORKING ORDER

,i_WARNING: Disconnect the

spark plug before performing mainte- nance except carburetor adjustments.

• Have all chain saw service performed by a qualified service dealer with the exception of the items listed in the MAINTENANCE section of this manual.

• Make certain the saw chain stops moving when the throttle trigger is released. For correction, refer to

CARBURETOR ADJUSTMENT.

• 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 operator's 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 engine.

• 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.

• Empty the fuel tank before storing or transporting the unit. Use up fuel left in

the carburetor by starting the engine and letting it run until it stops.

• Store the unit and fuel in an area where fuel vapors cannot reach

sparks or open flames from water

heaters, electric motors or switches,

furnaces, etc.

KICKBACKSAFETY FEATURES

_, WARNING: The following fea- tures are included on your saw to help

reduce the 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 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 danger zone on the bar tip. This type

of bar has been demonstrated to sig- nificantly reduce the number and se- riousness of kickbacks when tested in accordance with ANSI B175.1.

CHAIN BRAKE

• Chain Brake, designed to stop tile chain in the event of kickback.

,AWARNING: WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A KICK- BACK. Kickback is a lightning fast action

which throws the bar and rotating chain

back and up toward the operator. Kick- back can be caused by allowing 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 INTOYOUR SAW. YOU SHOULD USETHE SAW PROPERLY AND CAREFULLY TOAVOID KICKBACK.

Reduced-kickback guide bars and low- kickback saw chains reduce the chance

and magnitude of kickback and are rec- ommended. Your saw has a low kick-

back chain and bar as original equip- ment. Repairs on a chain brake should

be made by an authorized Sears Ser-

vice Center. Take your unit to the place

of purchase if purchased from a servic- ing dealer, or to your nearest Sears Ser-

vice 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 devices built into

your saw.

CHAIN BRAKE

The CHAIN BRAKE is a device designed to stop the chain if kickback occurs. The

chain brake activates automatically in

the event of kickback. The chain brake

activates manually if the front hand guard is pushed forward. The chain

brake is disengaged by pulling the front hand guard back toward the front handle as far as possible. CHAIN TENSION It is normal for a new chain to stretch

during the first 15 minutes of operation.

You should check your chain tension frequently, See CHAINTENSION under the MAINTENANCE section.

_IbWARNING: Muffler is very hot

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

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. 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 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. Included

with this saw is a 3.2 ounce container of oil. Pour the entire contents of this con-

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

DO NOT USE automotive 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 is thoroughly mixed. Always read and follow the safety rules relat- ing 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 system should be

emptied before storage for 30 days or

longer. Drain the gas tank, start the en-

gine and let it run until the fuel lines and

carburetor are empty. Use fresh fuel

next season. Never use engine or car-

buretor cleaner products in the fuel tank

or permanent damage may occur.

See the STORAGE section for additional

information

CHAIN BRAKE

Ensure chain brake is disengaged by

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

chain brake must be disengaged before

cutting with the saw. _IWARNING: 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 contact with the muffler. A hot muffler can

cause serious burns.

STOPPING YOUR ENGINE

• Release tile throttle trigger.

• Move ON/STOP switch to the STOP position.

STARTING POSITION

• To start the engine, bold tile saw

firmly on the ground as illustrated.

idle lever in completely (to the OFF CHOKE position) and then following the

warm engine starting procedure listed

above. Ensure the ON/STOP switch is in the ON position. Starting could require pulling the start-

er rope handle many times depending on how badly the unit is flooded. If en-

gine fails to start, refer to the TROU- BLESHOOTING TABLE or call

1-800-235-5878. CHAIN BRAKE

_WARNING: Ifthe 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 replaced if any part is worn to less

than 0.020" (0.5 ram) 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 near-

est Sears Service 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.

CAUTION: The chain brake must be

checked several times daily. The en- gine must be running when performing

this procedure. This is the only instance when the saw should be

placed on the ground with the engine running.

Place the saw on firm ground. Grip the

rear handle with your right hand and the front handle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against

the hand guard without releasing your grip around the front handle. The chain

should stop immediately. Inertia activating function control

,I_WARNING: When performing

the following procedure, the engine must be turned off.

Grip the rear handle with your right hand and the front handle with your left hand.

Hold the chain saw approximately 14

inches (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 top 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, plas- tics, masonry, non-wood building ma-

terials, etc.

• Stop the 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 possibility of kickback.

• Practice cutting a few small logs us- ing the following techniques to get the "feel" of using your saw before

you begin a major sawing operation.

• Squeeze the throttle trigger and allow 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. If

you force the cut, damage to the

bar, chain, or engine can result.

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

the engine to idle. Ifyou run the saw at full throttle without a cutting load,

unnecessary wear can occur to the

chain, bar, and engine. To maxi-

mize operating efficiency, do not run the engine for longer than 30

seconds at a time at full throttle.

• 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 after cutting.

TREE FELLING TECHNIQUES Ai_WARNING: Check for broken or

dead branches which can fall while cut-

ting causing serious injury. Do not cut

near buildings or electrical wires ifyou do not know the direction of tree fall, nor

cut at night since you will not be ale to see well, nor during bad weather such

as rain, snow, or strong winds, etc. If

the tree makes contact with any utility

line, the utility company should be noti-

fied immediately.

• 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 di-

rection.

Natural conditions that can cause a tree

to fall in a particular direction include:

• The wind direction and speed.

• The lean of the tree. The lean of a tree might not be apparent due to un-

even or sloping terrain. Use a plumb or level to determine the direction 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. Check for broken or dead branches which can fall on you while cutting. Make sure there is enough

room for the tree to fall. Maintain a dis- tance of 2-1/2tree 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 a clear retreat path to the rear and diagonal to the line of fall.

FELLING LARGE TREES

(6 h_ches(15 cm) h_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 will tend to fall into 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 THE TREE

• Make notch cut by cutting the top of

the notch first. Cut through 1/3of the diameter of the tree. Next complete

the notch by cutting the bottom of the notch. See illustration. Once the notch is cut remove the notch of

wood from the tree.

Final (felling) cut here, 2 inches (5 era) above center of notch.

Firstout } ,z'; I /

• 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 (5

cm) 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 inthe

wrong direction.

Hinge holds tree on stump and helps control fall

Closing of notch

NOTE: Before felling cut is complete, use wedges to open the cut if 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, 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 cut down a partially fallen tree

with your saw. 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. _IWARNING: 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.

TYPES OF CUTTING USED FOR

BUCKING

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. 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.

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.

Second cut

First cut on compression side of log

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 for cutting 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 below for

your first and second cut)

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

• Finish with your second cut.

Using a log for support

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. ,_WARNING: Neverturn 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

moving chain to contact any other branches or objects at the nose of the

guide bar when limbing or pruning. Al- lowing 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 posi- tion which can cause you to lose your

balance or control of the saw. IMPORTANT POINTS

• Work slowly, keeping both bands firmly

gripped on the saw. Maintain secure footing and balance.

• Watch out for springpoles. Springpoles

are small size limbs which can catch the saw chain and whip toward you or

pull you off balance. Use extreme cau- tion when cutting small size limbs or

slender material.

• Be alert for springback. Watch out for

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.

• Keep a clear work area. Frequently

clear branches out of the way to avoid tripping over them.

LIMBING

• Always limb a tree after it is cut

down. Only then can limbing be done safely and properly.

• 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. Cut from the side of the tree

opposite the branch you are cutting.

• Remove larger, supporting branches with the cutting techniques described

in BUCKING WITHOUT A SUPPORT

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

could cause limbs to fall and pinch the

saw.

PRUNING

_WARNING: Limit pruning to limbs

shoulder height or below. Do not cut if branches are higher than your shoulder.

Get a professional to do the job.

• Make your first cut 1/3of the way through the bottom of the limb.

• Next make a 2nd cut all the way through the limb. Then cut a third

overcut leaving a 1 to 2 inch (2.5 to 5 cm) collar from the truck of the tree.

GENERAL RECOMMENDATIONS

The warranty on this unit does not cov- er items that have been subjected to

operator abuse or negligence. To re- ceive full value from the warranty, the operator must maintain unit as

instructed in this manual. Various ad- justments will need to be made period-

ically to properly maintain your unit.

• Once a year, replace the spark plug, air filter, and check guide bar and chain for wear. A new spark plug and

air filter assures proper air-fuel mixture and helps your engine run better and

last longer.

CHECK FOR DAMAGED OR WORN PARTS

Contact your Sears Service Center for replacement of damaged or worn parts.

NOTE: It is normal for a small amount of

oil to appear under the saw after engine stops. Do not confuse this with a leaking

oil tank.

• ON/STOP Switch - Ensure ON/STOP switch functions properly by moving the switch to the STOP position. Make sure engine stops; then restart engine

and continue.

• Fuel Tank - Do not use saw iffuel tank shows signs of damage or leaks.

• Oil Tank - Do not use saw if oil tank shows signs of damage or leaks.

CHECK FOR LOOSE FASTENERS AND PARTS

• Bar Nuts

• Chain

• Muffler

• Cylinder Shield

• Air Filter

• Handle Screws

• Vibration Mounts

• Starter Housing

• Front Hand Guard

CHECK CHAIN TENSION

_ik 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 especially 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.

2. Loosen bar nuts until they are finger tight against the clutch cover.

3. Turn adjusting screw clockwise un- til chain solidly contacts bottom of

guide bar rail.

4. Using bar tool, roll chain around

guide bar to ensure all links are in bar groove.

5. Lift up tip of guide bar to check for

sag. Release tip of guide bar, then

turn adjusting screw until sag does

not exist.

6. While lifting tip of guide bar, tighten

bar nuts securely with the bar tool.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A

dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARP-

ENING. CHECK GUIDE BAR

Conditions which require guide bar 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.

• Loosen and remove bar nuts and clutch cover. Remove bar and chain

from saw.

• Clean the oil holes and bar groove after each 5 hours of operation.

7. Use the screwdriver end of the bar tool to move chain around guide

bar.

8. If chain does not rotate, it is too tight. Slightly loosen bar nuts and

loosen chain by turning the adjust- ing screw 1/4 turn counterclock-

wise. Retighten bar nuts.

9. If chain is too loose, it will sag be-

low the guide bar. DO NOT operate

the saw if the chain is loose.

_,WARNING: If the saw is oper- ated with a loose chain, the chain could jump offthe guide bar and result in serious injury.

• Burring of guide bar rails is a normal process of rail wear. Remove these

burrs with a flat file.

• When rail top is uneven, use a flat

file to restore square edges and sides.

Worn Groove Correct Groove

Replace guide bar when the groove is

worn, the guide bar is bent or cracked,

or when excess heating or burring of the rails occurs. If replacement is necessary, use only the guide bar specified for your

saw in the repair parts list or on the de-

cal located on the chain saw. CHECK FUEL MIXTURE LEVEL
