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.

• 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.

2

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, 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.

_._ _,_ Kickback Path

k_...:+j._,_ Avoid Obstructions

Clear The Worm

A

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. 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

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.

• Position your left hand on the front

handlebar so it is in a straight line with

your right hand on the rear handle

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 ANS! B175.1.

AI_, 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

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.

SAFETY NOTICE: Exposure to vibra-

tions through prolonged use of gasoline

powered hand tools could cause blood

vessel or nerve damage in the fingers,

hands, and joints of people prone to
circulation disorders or abnormal swell-

ing. Prolonged use in cold weather has
been linked to blood vessel damage in
otherwise healthy people. If symptoms

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. If you 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

BEFORESTARTING ENGINE

,_L 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

,_L 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 printed 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, start 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.
,_,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.

TROUBLESHOOTING TABLE or call

1-800-235-5878.

CHAIN BRAKE

,_ WARNING: If tile 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.

Grip the rear handle with your right hand

and the front handle with your left hand.

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 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

'_ WARNING: Check for broken or

dead branches which can fall while cut-

ting 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. 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

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.

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.

NOTCHCUTAND 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.

Firstcut ) =,. j

Second cut_ j \ e

• 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.

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 to signs that the tree is ready

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

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

down, and get away quickly on your
planned retreat path.

• DO NOT use your saw to 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

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

logs into a clear area before cutting
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 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 begins on the top side of
the log with the bottom of the saw

against the log. When overcutting use

light downward pressure.

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 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. (Re-

fer to the illustrations below for your
first and second cut).

• Your first cut should extend 1/3 of the

diameter of the log.

• Finish with your second cut.

LIMBING AND PRUNING

WARNING: Be alert for and guard

against kickback. Do not allow the mov-
ing chain to contact any other branches
or objects at the nose of the guide bar

when limbing or pruning. Allowing such
contact can result in serious injury.

WARNING: Never climb into a

tree to _imb or prune. Do not stand on

ladders, platforms, a log, or in any po-
sition which can cause you to lose

your balance or control of the saw.

IMPORTANT POINTS

• Watch out for springpoles.
Springpoles are small size limbs

which can whip toward you, or pull
you off balance. Use extreme cau-
tion when cutting small size limbs.

• Be alert for springback from any
branches that are bent or under

pressure. Avoid being struck by the
branch or the saw when the tension

in the wood fibers is released.

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

LIMBING

• Limb a tree only after it is cut down.

• Leave the larger limbs underneath

the felled tree to support the tree as
you work.

• Start at the base of the felled tree

and work toward the top, cutting

branches and limbs. Remove small
limbs with one cut.

• Keep the tree between you and the
chain.

• Remove larger branches with the
cutting techniques described in
BUCKING WITHOUT A SUPPORT.

PRUNING

_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.

• 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

_i 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.

Chain Brake

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 chain brake

nuts and loosen chain by turning
the adjusting screw counterclock-

wise. Retighten chain brake 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.

_i, WARNING: If the saw is operated
with a loose chain, the chain could
jump offthe 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.
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.

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 filter using hot soapy
water. Rinse with clean cool water.

Air dry completely before reinstalling.

5. Lightly oil air filter before installing to
improve the efficiency of air filter.

CHAIN ADJUSTMENT

See CHAIN TENSION in MAINTENANCE
section.

CARBURETOR ADJUSTMENT

_IWARNING: The chain will be
moving during most of this procedure.

Wear your protective equipment and ob-
serve all safety precautions. During the
low speed mixture adjustment recheck
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 dam-
age the engine as well as the carbure-

tor. If you require further assistance or
are unsure about performing this proce-

dure, call our customer assistance 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 adjusting the

carburetor.

The carburetor has been carefully set at
the factory. Adjustments may be neces-

sary if you notice any of the following
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,

17

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-
formance of the saw while cutting, ad-
just the high speed mixture setting in

1/16-turn increments as follows:

• Turn the high speed mixture screw (H)
clockwise until saw has good power in

the cut with no hesitation. Do not ad-
just by sound or speed, but judge by

how well the saw performs in the cut.

• Turn the high speed mixture screw (H)
counterclockwise if the saw has

speed, but dies in the cut or lacks

power in the cut.

After completing adjustments, check
for acceleration and chain movement

at idle. Reset if necessary.

Acceleration Check

If the engine dies or hesitates instead of
accelerating, turn the low speed mixture

screw (L) counterclockwise until you
have smooth acceleration with no chain

movement at idle.

WARNING: Perform the following

steps after each use:

• Allow the engine to cool, and secure
the unit before storing or transport-
ing.

• Store chain saw and fuel in a well
ventilated area where fuel vapors

cannot reach sparks or open flames
from water heaters, electric motors or

switches, furnaces, etc.

• Store chain saw with all guards in
place and position chain saw so that
any sharp object cannot accidentally
cause injury.

• Store chain saw well out of the reach
of children.

SEASONAL STORAGE

Prepare your unit for storage at the

end of the season or if it will not be
used for 30 days or more.

If your chain saw is to be stored for a

period of time:

• Clean saw thoroughly before stor-
age.

• Store in a clean dry area.

• Lightly oil external metal surfaces
and guide bar.

• Oil the chain and wrap it in heavy pa-
per or cloth.

FUEL SYSTEM

Under FUELING ENGINE in the OPERA-

TION section of this manual, see mes-

sage labeled IMPORTANT regarding

the use of gasohol in your chain saw.

Fuel stabilizer is an acceptable alter-
native in minimizing the formation of

fuel gum deposits during storage. Add
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 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.

OTHER

• Do not store gasoline from one sea-
son to another.

• Replace your gasoline can if it starts
to rust.

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

repairs should be completed in a rea-

sonable amount of time, not to exceed
