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 the use of your saw to adult

users who understand and can fol-

low the safety rules, precautions,

and operating instructions found in

this manual.

Shoes _ Safety Chaps

• 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 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 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.

OPERATEYOUR 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, 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 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 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.

Xf_'_ _ Kickback Path

Avoid Obstructions

_h, 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. Fol-

low manufacturer's chain sharpening

and maintenance instructions. Check

tension at regular intervals, but never

with engine running. Make sure chain

brake 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 reentering

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 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 cut open.

MAINTAIN CONTROL

KICKBACKSAFETY 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 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.

AIL A

A,mWARNINu: 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

which could result in serious injury or

even death. DO NOT RELY UPON ANY

OF THE SAFETY 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 reduce the chance and magni-

tude of kickback and are recom-

mended. Your saw has a tow kickback

chain and bar as original equipment.

Repairs on a chain brake should be

made by an authorized Sears Service

Center. Take your unit to the place of

purchase 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 safety devices

built into your saw.

quently. See CHAIN TENSION under the

SERVICE AND ADJUSTMENTS section.

,elWARNING: 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 fl. oz.).

Lack of oil wilt 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). DO NOT USE automotive oil

or boat oil. These oils will cause en-

gine damage. When mixing fuel follow

the instructions printed on the oil con-

tainer.

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 sys-

tem 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 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.

_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

• To start the engine, hold the saw

firmly on the ground as illustrated.

Make sure the chain is free to turn

without contacting any object.

CHAIN BRAKE

_WAI-(NINL_: 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

which could result in serious injury or

even death. DO NOT RELY UPON ANY

OF THE SAFE-IY 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 reduce the chance and magni-

tude of kickback and are recom-

mended. Your saw has a low kickback

chain and bar as original equipment. 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 replaced 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 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)orautomatically(bysudden

movement).

Braking function control

CAUTION: The chain brake must be

checked several times daily. The engine

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. Hold han-

dles with both hands and apply full

throttle. Activate the chain brake by turn-

ing your left wrist against the hand guard

without releasing your grip around the

front handle. The chain should stop im-

mediately.

Inertia activating function control

_, WARNING: When performing the

following procedure, the engine must

be turned off.

Hold the chain saw approximately 14"

(35 cm) above a stump or other wood-

en surface. Release your grip on the

front handle and 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 us-

ing the following steps. This wilt 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

_,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. If the tree does make con-

tact with any utility line, the utility com-

pany should 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.

• 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. 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.

• 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

FELLINGLARGE 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 _--_ ._. _

Secondcut_i /\ _ge

• 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

Closing

of notch

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.

CUTTING AFALLEN 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.

TYPESOFCUTTINGUSEDFOR

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. 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 awedge 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.

Overcutting _&_U

•_" ._\_

Unaercutting _;'.,%

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 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.

First cut on compression side of log

Second cut

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 illustration 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.

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 instruct-

ed in this manual. Various adjustments

will need to be made periodically to

properly maintain your unit.

• Once a year, replace the spark plug,

air filter element, and check guide bar

and chain for wear. A new spark plug

and air filter element assures proper

air-fuel mixture and helps your engine

run better and last longer.

CHECK FOR DAMAGED OR

WORN PARTS

Contact Sears Service Center for re-

placement of damaged or worn parts.

NOTE: It is normal for a small amount

of oil to appear under the saw after en-

gine 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 if fuel

tank shows signs of damage or

leaks.

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.

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 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.

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 filter using hot soapy

water. Rinse with clean cool water.

CHAIN ADJUSTMENT

See CHAIN TENSION in MAINTENANCE

section.

CARBURETOR ADJUSTMENT

,_ WARNING: The chain will be

moving during most of this procedure.

Wear your protective equipment and

observe all safety precautions. During

the low speed mixture adjustment re-

check idle speed after each turn of the

screw. The chain must not move at idle

speed.

Carburetor adjustment is critical and if

done improperly can permanently

damage the engine as well as the car-

buretor. If you require further assis-

tance or are unsure about performing

this procedure, call our customer as-

sistance help line at 1-800-235-5878.

Old fuel, a dirty air filter, dirty fuel filter,

or flooding may give the impression of

an improperly adjusted carburetor.

Check these conditions before adjust-

ing the carburetor.

The carburetor has been carefully set

at the factory. Adjustments may be

necessary if you notice any of the fol-

lowing conditions:

• Chain moves at idle. See IDLE

SPEED-T under adjusting procedure.

• Saw will not idle. See IDLE SPEED-T

and LOW SPEED MIXTURE-L under

adjusting procedure.

• Engine dies or hesitates when it

should accelerate. See ACCELERA-

TION CHECK under adjusting

procedure.

• Loss of cutting power. See HIGH

SPEED MIXTURE - H under adjusting

procedure.

There are three adjustment screws on

the carburetor. They are labeled H, L,

and T. They are located in the area just

above the primer bulb.

ADJUSTING PROCEDURE

CAUTION: Do not force plastic limiter

caps on screws beyond the built-in

stops or damage will occur.

Initial Settings

1. Turn both mixture screws (L and H)

counterclockwise until they stop.

2. Turn the idle speed screw (T)

clockwise until it stops. Then turn it

counterclockwise 4 and 1/2 turns.

3. Start engine and let it run for 3 min-

utes, then proceed to adjust

screws according to the instruc-

tions below. If engine performance

at initial settings is acceptable, no

further adjustments are necessary.

If engine does not start, refer to the

TROUBLESHOOTING TABLE. If still

unable to remedy situation, call

1-800-235-5878.

Idle Speed-T

Allow engine to idle. If the chain

moves, idle is too fast. If the engine

stalls, idle is too slow. Adjust speed

until engine runs without chain move-

ment (idle too fast) or stalling (idle too

slow).

• Turn idle screw (T) clockwise to in-

crease engine speed.

• Turn idle screw (T) counterclockwise

to decrease engine speed.

Low Speed Mixture-L

Allow engine to idle. Then accelerate

the engine and note performance. If

engine hesitates, bogs down, or

smokes during acceleration, turn low

speed mixture screw (L) clockwise in

1/16-turn increments until performance

is satisfactory. Repeat this procedure

as necessary for proper adjustment.

After completing adjustments, check

for acceleration and chain movement

at idle. Reset if necessary.

High Speed Mixture-H

DO NOT operate engine at full throttle

for prolonged periods while making ad-

justments. Damage to the engine can

occur. Make a test cut. Based on per-

stabilizer to the gasoline in the fuel

tank or fuel storage container. Follow

the mix instructions found on stabilizer

containers. Run engine at least 5 min-

utes after adding stabilizer.

Craftsman 40:1,2-cycle engine oil (air

cooled) is especially blended with fuel

stabilizer. If you do not use this Sears

oil, you can add a fuel stabilizer to your

fuel tank.

ENGINE

• Remove spark plug and pour 1 tea-

spoon of 40:1,2-cycle engine oil (air

cooled) through the spark plug open-

ing. Slowly pull the starter rope 8 to

10 times to distribute oil.

• Replace spark plug with new one of

recommended type and heat range.

• Clean air filter.

• Check entire unit for loose screws,

nuts, and bolts. Replace any dam-

aged, broken, or worn parts.

• At the beginning of the next season,

use only fresh fuel having the proper

gasoline to oil ratio.

YOUR WARRANTY RIGHTS AND

OBLIGATIONS: The U. S. Environ-

mental Protection Agency and Sears,

Roebuck and Co., U.S.A., are pleased

to explain the emissions control sys-

tem warranty on your lawn and garden

equipment engine. All new utility and

lawn and garden equipment engines

must be designed, built, and equipped

to meet the stringent anti-smog stan-

dards. Sears must warrant the emis-

sion control system on your lawn and

garden equipment engine for the peri-

ods of time listed below provided there

has been no abuse, neglect, or im-

proper maintenance of your lawn and

garden equipment engine. Your emis-

sion control system includes parts

such as the carburetor and the ignition

system. Where a warrantable condition

exits, Sears will repair your lawn and

garden equipment engine at no cost to

you. Expenses covered under warran-

ty include diagnosis, parts and labor.

MANUFACTURER'S WARRANTY

COVERAGE: If any emissions related

part on your engine (as listed under

Emissions Control Warranty Parts List)

is defective or a defect in the materials

or workmanship of the engine causes

the failure of such an emission related

part, the part will be repaired or re-

placed by Sears. OWNER'S WAR-

RANTY RESPONSIBILITIES: As the

lawn and garden equipment engine

owner, you are responsible for the per-

formance of the required maintenance

listed in your instruction manual. Sears

recommends that you retain all re-

ceipts covering maintenance on your

lawn and garden equipment engine,

but Sears cannot deny warranty solely

for the lack of receipts or for your fail-

ure to ensure the performance of all

scheduled maintenance. As the lawn

and garden equipment engine owner,

you should be aware that Sears may

deny you warranty coverage if your

lawn and garden equipment engine or

a part of it has failed due to abuse, ne-

glect, improper maintenance, unap-

proved modifications, or the use of

parts not made or approved by the

original equipment manufacturer. You

are responsible for presenting your

lawn and garden equipment engine to

a Sears authorized repair center as

soon as a problem exists. Warranty

repairs should be completed in a rea-

sonable amount of time, not to exceed

30 days. If you have any questions

regarding your warranty rights and re-

sponsibilities, you should contact your

nearest authorized service center or

call Sears at 1-800-469-4663 WAR-

RANTY COMMENCEMENT DATE:

The warranty period begins on the

date the lawn and garden equipment

engine is purchased. LENGTH OF

COVERAGE: This warranty shall be

for a period of two years from the initial

date of purchase. WHAT IS COV-

ERED: REPAIR OR REPLACEMENT

OF PARTS. Repair or replacement of

any warranted part will be performed at

no charge to the owner at an approved

Sears servicing center. If you have any

questions regarding your warranty

rights and responsibilities, you should

contact your nearest authorized ser-

vice center or call Sears at

1-800-469-4663. WARRANTY PE-

RIOD: Any warranted part which is not

scheduled for replacement as required

maintenance, or which is scheduled

only for regular inspection to the effect

of "repair or replace as necessary"

shall be warranted for 2 years. Any

warranted part which is scheduled for

replacement as required maintenance

shall be warranted for the period of

time up to the first scheduled replace-

ment point for that part. DIAGNOSIS:

The owner shall not be charged for

diagnostic labor which leads to the de-

termination that a warranted part is de-

fective if the diagnostic work is per-

formed at an approved Sears servicing

center. CONSEQUENTIAL DAM-

AGES: Sears may be liable for dam-

ages to other engine components

caused by the failure of a warranted

part still under warranty. WHAT IS

NOT COVERED: All failures caused

by abuse, neglect, or improper mainte-

nance are not covered. ADD-ON OR

MODIFIED PARTS: The use of add-on

or modified parts can be grounds for dis-

allowing a warranty claim. Sears is not

liable to cover failures of warranted

parts caused by the use of add-on or

modified parts. HOW TO FILE A

CLAIM: If you have any questions re-

garding your warranty rights and re-

sponsibilities, you should contact your

nearest authorized service center or
