• 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 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.

• D_ not handle or operate a chain _aw 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

especiallyifyouarefelling 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 sawonly 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, improperly adjusted, or not

completely and securely assembled. Always replace bar, chain, hand

guard, chain brake, or other pads 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-

sodes 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 pads, 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 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.

WARNING: Avoidkickbackwhich

woodclosesin andpinchesthesaw chaininthecut.Contactingaforeign

objectinthewoodcanalsoresultin

lossof chainsawcontrol.

• 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 cha,n 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 stoppingpulls the saw for- ward and away from the operator and could easily 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 surpdse which contdbutes to acci-

dents.

any object at the tip of the guide bar.

_ Never let the moving chain contact

Keep working area free from obstruc-

tions such as other trees, branches,

rocks, fences, etump6, etc. Eliminate or avoid any obstruction that your saw chain could hit while cutting.

• When cuffing a branch, do not let the

guide bar contact another branch or other objects around it

• Keep saw chain sharp and propedy tensioned. A loose or dull chain can

increase the chance of kickb_lck. Fol- low manufacturer's chain sharpening

and maintenance instructions. Check tension at regular intervals, but never with engine running. Make su[e chain

brake nuts are securely tightened.

• Begin and continue cuttin_ at ful! speed. If the chain is moving at a slower speed, there is greate_ chance

of kickback occurring.

• Use extreme caution when repntering 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 pinph 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 Ftaterial

to pinch the top of or otherwise stop

the chain.

• Do not cut more than one log at a

time.

• Do not twist saw as 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 cpt open.

• Do not overreach. You could be drawn or thrown off balance and lose control.

• Do not cut above shoulder height. It is

difficult to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

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 ofyour 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-lina" 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.

_,WARNING: WE DO NOT REP-

RESENT AND 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

whk_h could result inserious 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.

• lip 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.

It is normal for a new chain to stretch

during first 15 minutes of operation. You should check your chain tension fre- quenUy. See CHAIN TENSION under the

SERVICE AND ADJUSTMENTS section.

_lbWARNING: 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 2-cycle air-cooled engine oil.

We recommend Craftsman brand oil.

Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2

ounces of oil with 1 gallon of unleaded gasoline. Included with this saw is a

3.2 ounce container of Craftsman brand 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 pdnted on the oil container.

Once oil is added 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 system should be emptied before storage for 30 days or

longer. Drain the gas tank, stad the en- gine and let it run until the fuel lines and

carburetor are empty. Use fresh fuel next season, See STORAGE instructions

for additional information.

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.

,Ira 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 sedous bums. 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.

TROUBLESHOOTING TABLE or call

1-800-235-5878.

CHAIN BRAKE _ WARNING: If the brake band is

wom 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.

OPERATING TIPS

• Check chain tension before first use

and after t 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 us- ing the following steps. This will help you get the "feel" of using your saw

before you begin a major sawing op- eration.

• 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 engine before setting saw down.

TREE FELLING TECHNIQUES 40&WARNING: Check for broken or

dead branches which can fall while cutting causing serious injury. Do not cut qear buildings or electrical wires if

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

be a_01eto 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

shoqld be notified 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.

• Th e 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. These 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.

• S_urrounding 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.

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

whpre cuts are to be made.

,_,, Plan a clear retreat path

(2"'='"=_" Direction of fall

FELUNG 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 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 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 tree.

Felling cut here

First cut =.. /

Notch _ _ ._.. ""_-"lr

• 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

controlfall

Opening of felling cut

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, 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.

cu'n'ING 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 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 logs into a clear area before cutting them

by pulling out exposed and cleared logs first.

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

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

Overcutting begins onthe top side of the logwith the bottom ofthe saw

against the log.When overcutting use lightdownward pressure.

_tting Und_rc_in_g

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: Never tum 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 sedous injury.

Firstcut 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 iUustrations 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

I stCut

_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.

Spdngpoles 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 spdngback 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 tdpplng 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 A SUPPORT.

• 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.

eC_d cut

_WARNING: Limit pruning to limbs shoulder height or below. Do not cut if

branches are higher than your shoul- 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

falls easily on the second cut.

,_ 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

or when any sag in the chain is noted.

5. Return handle of adjustment knob to original position.

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

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 chain brake

nuts and chain brake. Remove bar and chain from saw.

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

section.

CLEAN AIR FILTER

A dirty air filter decreases the life and

performance of the engine and in- creases fuel consumption and harmful

emissions. Always clean your air filter after 15 tanks of fuel or 5 hours of op- eration, whichever comes first. Clean

more frequently in dusty conditions. A used air filter can never be completely

cleaned. It is advisable to replace your air filter with a new one after every 50 hours of operation, or annually, which-

ever comes first. To clean filter:

1. Loosen 3 screws on cylinder

cover.

2. Remove cylinder cover.

3. Remove air filter.

4. Clean the air tilter using hot soapy

water. Rinse with clean cool water. Air dry completely before reinstal-

ling.

5. Liqhfiy oil air filter before installing

to improve the efficiency of air filter.
