ular users should have hearing

checked regularly as chain saw noise
can damage hearing.

• Secure hair above shoulder length. Do

not wear loose clothing or jewelry; they

can get caught in moving parts.

• Keep all parts of your body away from
the chain when the engine is running.

• Keep children, bystanders, and ani-

mals a minimum of 30 feet (10 me-

ters) away from the work area when
starting and using the saw.

• Do not handle or operate a chain saw
when you are fatigued, ill, or 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

the cut is completed.

• Stop engine before setting saw down.

• Hand carry saw only when engine is
stopped. Carry with muffler away

from body; guide bar & chain project-
ing behind you; guide bar preferably
covered with a scabbard.

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

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

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

or is otherwise removed.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

,_LWARNING: Disconnect the

spark plug before performing mainte-

nance except carburetor adjustments.

• Have all chain saw service performed
by a qualified service dealer with the

exception of the items listed in the
MAINTENANCE section of this manual.

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

released. For correction, refer to
CARBURETOR ADJUSTMENT.

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

• Keep caps and fasteners securely
tightened.

• Nonconforming replacement compo-
nents or the removal of safety devices

may cause damage to the unit and
possible injury to the operator or by-

standers. Use only Craftsman acces-
sories and replacement parts as rec-
ommended. Never modify your saw.

• Maintain chain saw with care.

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

• Follow instructions for lubricating and
changing accessories.

• Check for damaged parts. Before fur-
ther use of the chain saw, a guard or

other part that is damaged should be
carefully checked to determine that it
will operate properly and perform its

intended function. Check for alignment

of moving parts, binding of moving

parts, breakage of parts, mounting and

any other conditions that may affect its
operation. A guard or other part that is

damaged should be properly repaired
or replaced by a Sears Service Center

unless otherwise indicated elsewhere
in the operator's manual.

• When not in use, chain saws should

be stored in a dry, high or locked-up
place out of the reach of children.

• When storing saw, use a scabbard or
carrying case.

HANDLE FUEL WITH CAUTION

• Do not smoke while handling fuel or
while operating the saw.

• Eliminate all sources of sparks or
flame in the areas where fuel is

mixed or poured.

• Mix and pour fuel in an outdoor area
and use an approved, marked con-

tainer for all fuel purposes. Wipe up
all fuel spills before starting saw.

• Move at least 10 feet (3 meters) from
fueling site before starting engine.

• Turn the engine off and let saw cool

in a non-combustible area, not on

dry leaves, straw, paper, etc. Slowly

remove fuel cap and refuel unit.

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

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

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

sparks or open flames from water

heaters, electric motors or switches,

furnaces, etc.

GUARD AGAINST KICKBACK
Follow all safety rules to help avoid

kickback and other forces which can
result in serious injury.

_'_\ j_; Kickback Path

.

,_kWARNING: Avoid kickback

which can result in serious injury.

Kickback is the backward, upward or

sudden forward 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 re-

sult 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 hap-
pen. With a basic understanding of

kickback, you can reduce the ele-
ment of surprise which contributes to

accidents.

• Never let the moving chain contact
any object at the tip of the guide bar.

• Keep the working area free from ob-
structions such as other trees,
branches, rocks, fences, stumps,

etc. Eliminate or avoid any
obstruction that your saw chain could

hit while you are cutting.

• When cutting a branch, do not let the
guide bar contact branch or other ob-

jects 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 the engine running. Make sure
the bar nuts are securely tightened.

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

slower speed, there is greater
chance of kickback occurring.

• Use extreme caution when re-enter-

ing a previous 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 Reduced-Kickback Guide

Bar and Low-Kickback Chain speci-

fied for your saw.

Avoid Pinch-Kickback:

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

to pinch the top of or otherwise stop
the chain.

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

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

bucking.

Avoid Pull-In:

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

against wood.

• Use wedges made of plastic or wood.

Never use metal to hold the cut open.

MAINTAIN CONTROL

• A good, firm grip on the saw with both

hands will help you maintain control.
Don't let go. Grip the rear handle with

KICKBACKSAFETYFEATURES

_IkWARNING: The following fea-
tures are included on your saw to help

reduce the hazard of kickback; however,
such features will not totally eliminate
this danger. Do not rely only on safety
devices. Follow all safety rules to help

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

• Front Hand Guard, designed to reduce
the chance of your left hand contact-

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

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

dles and "in-line" with each other. The
spread and "in-line" position of the
hands provided by this design work
together to give balance and resis-

tance in controlling the pivot of the
saw back toward the operator if kick-

back occurs.

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

reduces the size of the kickback
danger zone on the bar tip. This type

of bar has been demonstrated to sig-
nificantly reduce the number and se-

riousness of kickbacks when tested
in accordance with ANSI B175.1.

CHAIN BRAKE

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

_ILWARNING: WE DO NOT REP-

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

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

which throws the bar and rotating chain
back and up toward the operator. Kick-
back can be caused by allowing contact

of the bar tip in the danger zone with
any hard object. Kickback can also be
caused by pinching the saw chain along

the top of the guide bar. This action may

push the guide bar rapidly back toward

the operator. Either of these events may

cause you to lose control of the saw
which could result in serious injury or

even death. DO NOT RELY UPON ANY OF
THE DEVICES BUILT 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 magnitude of kickback and are rec-

ommended. Your saw has a low kick-
back chain and bar as original equip-

ment. Repairs on a chain brake should
be made by an authorized Sears Ser-

vice Center. Take your unit to the place

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

vice Center

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

kicking guide bar up and back toward

operator.

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

bar rapidly back toward the operator.

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

could result in serious injury. Do not

rely exclusively upon devices built into

your saw.

CHAIN BRAKE

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

chain brake activates automatically in

the event of kickback. The chain brake

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

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

CHAIN TENSION
It is normal for a new chain to stretch

during the first 15 minutes of operation.

You should check your chain tension

each time before you start the chain
saw. See CHAIN TENSION under the

MAINTENANCE section.

,_WARNING: Ifthe saw is oper-

ated with a loose chain, the chain
could jump offthe guide bar and result
in serious injury to the operator and/or
damage the chain making it unusable.

BEFORESTARTINGENGINE

_LWARNING: 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.

_,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

_LWARNING: Remove fuel cap
slowly when refueling.

This engine is certified to operate on

unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality synthetic 2-cycle air-cooled en-
gine oil. We recommend Craftsman

brand synthetic oil. Mix gasoline and
oil ata ratio of 40:1. A40:1 ratio is ob-

tained by mixing 3.2 ounces of oil with

1 gallon of unleaded gasoline. Included
with this saw is a 3.2 ounce container of

oil. Pour the entire contents of this con-
tainer into 1 gallon of gasoline to

achieve the proper fuel mixture.

DO NOT USE automotive or boat oil.
These oils will cause engine damage.

When mixing fuel follow the instruc-
tions printed on the oil container.

Once oil is added to the gasoline,
shake container momentarily to assure

that the fuel is thoroughly mixed. 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. Never use engine or car-

buretor cleaner products in the fuel tank

or permanent damage may occur.

See the STORAGE section for additional

information

CHAIN BRAKE

Ensure chain brake is disengaged by

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

chain brake must be disengaged before

cutting with the saw.

_LWARNING: The chain must not

move when the engine runs at idle

speed. If the chain moves at idle

speed refer to CARBURETOR ADJUST-

MENT within this manual. Avoid contact

with the muffler. A hot muffler can

cause serious burns.

STOPPING YOUR ENGINE

• Release the throttle trigger.

• 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.

er rope handle many times depending
on how badly the unit is flooded. If en-
gine fails to start, refer to the TROU-

BLESHOOTING TABLE or call
1-800-235-5878.

CHAINBRAKE

_EWARNING: Ifthe brake band is

worn too thin it may break when the
chain brake is triggered. With a broken

brake band, the chain brake will not

stop the chain. The chain brake must

be replaced if any part is worn to less
than 0.020" (0.5 mm) thick. Repairs on
a chain brake should be made by your

Sears Service Center. Take your unit
to the place of purchase or to the near-

est Sears Service Center.

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

the chain if kickback occurs.

• The inertia-activated chain brake is
activated if the front hand guard is

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

movement).

• If the brake is already activated, it is
disengaged by pulling the front hand

guard back toward the front handle
as far as possible.

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

Braking function control

CAUTION: The chain brake must be

checked several times daily. The en-
gine must be running when performing
this procedure. This is the only

instance when the saw should be
placed on the ground with the engine

running.
Place the saw on firm ground. Grip the

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

brake by turning your left wrist against
the hand guard without releasing your

grip around the front handle. The chain
should stop immediately.

Inertia activating function control

,_WARNING: When performing

the following procedure, the engine

must be turned off.

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

Hold the chain saw approximately 14

inches (35 cm) above a stump or other

wooden surface. Release your grip on
the front handle and use the weight of
the saw to let the 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,
after 1 minute of operation, and each
time before you start the chain saw.

See CHAIN TENSION in the MAINTE-
NANCE section.

• Cut wood only. Do not cut metal, plas-
tics, masonry, non-wood building ma-

terials, etc.

• Stop the saw if the chain strikes a
foreign object. Inspect the saw and

repair or replace parts as necessary.
If the chain jumps off the guide bar,
inspect the chain for damaged drive

links before reinstalling. Burrs on

drive links, which prevent them from

entering the groove of the guide bar,

can be removed with a flat file.

• Keep the chain out of dirt and sand.

Even a small amount of dirt will dull a

chain, increase the possibility of kick-

back, and require chain sharpening or
replacement.

• Practice cutting a few small logs us-

ing the following techniques to get

the "feel" of using your saw before
you begin a major sawing operation.

• Squeeze the throttle trigger and 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. Ex-
ert only light downward pressure.

If you force the cut, damage to the
bar, chain, or engine can result.

• Release the throttle trigger as

soon as the cut is completed, al-

lowing the engine to idle. If you
run the saw at full throttle without

a cutting load, unnecessary wear
can occur to the chain, bar, and

engine. To maximize operating

efficiency, do not run the engine
for longer than 30 seconds at a
time at full throttle,

• To avoid losing control when cut is

complete, do not put pressure on
saw at end of cut.

• Stop the engine before setting the
saw down after cutting.

TREE FELLING TECHNIQUES

_IkWARNING: 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 ale to
see well, nor during bad weather such
as rain, snow, or strong winds, etc. If

the tree makes contact with any utility

line, the utility company should be noti-
fied immediately.

• Carefully plan your sawing operation
in advance.

• Clear the work area. You need a clear
area all around the tree so you can
have secure footing.

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

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

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

rection.

Natural conditions that can cause a tree

to fall in a particular direction include:

• The wind direction and speed.

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

even or sloping terrain. Use a plumb
or level to determine the direction of
tree lean.

• Weight and branches on one side.

• Surrounding trees and obstacles.

Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the

operator. Check for broken or dead

branches which can fall on you while

cutting. Make sure there is enough

room for the tree to fall. Maintain a dis-

tance of 2-1/2tree lengths from the near-

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

Remove dirt, stones, loose bark, nails,

staples, and wire from the tree where
cuts are to be made.

Plan a clear retreat path to the rear

and diagonal to the line of fall.

_1_,<2, Plan a clear retreat path

"_'_/'L_

FELLING LARGE TREES
(6 inches (15 cm) 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 into

the notch.

NOTE: If the tree has large buttress
roots, remove them before making the

notch. If using saw to remove buttress
roots, keep saw chain from contacting
ground to prevent dulling of the chain.

NOTCH CUT AND FELLING THE

TREE

• Make notch cut by cutting the top of
the notch first. Cut through 1/3of the

diameter of the tree. Next complete
the notch by cutting the bottom of the

notch. See illustration. Once the
notch is cut remove the notch of

wood from the tree.

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

First cut I ,2'; I /

i/

Notch __" --_-,.,

After removing the wood from the

notch, make the felling cut on the op-
posite side of the notch. This is done

by making a cut about two inches (5

cm) higher than the center of the

notch. This will leave enough uncut

wood between the felling cut and the

notch to form a hinge. This hinge will
help prevent the tree from falling in the

wrong direction.

Hinge holds tree on stump and helps
control fall

NOTE: Before felling cut is complete,
use wedges to open the cut if necessary

to control the direction of fall. To avoid

kickback and chain damage, use wood

or plastic wedges, but never steel or iron
wedges.

• Be alert to signs that the tree is
ready to fall: cracking sounds, widen-

ing of the felling cut, or movement in
the upper branches.

• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.

• DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious

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

pull down the tree with a cable winch,
block and tackle, or tractor.

CUTTING A FALLEN TREE
(BUCKING)

Bucking is 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 such as

in a blown down area. Drag the logs
into a clear area before cutting by

pulling out exposed and cleared logs
first.

Use a wedge to remove pinched saw

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

OvercutUng begins on the top side of

the log with the bottom of the saw

against the log. When overcutting use
light downward pressure.

_L_ Overcutting _/

Undercutting ""-', b

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.

_ILWARNING: Nevertum 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.

TYPES OF CUTTING USED FOR

BUCKING

_I, WARNING: If saw becomes

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

force it out. You can lose control of the
saw resulting in injury and/or damage

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

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

the cut. To avoid kickback and chain
damage, do not use a metal wedge.

Do not attempt to restart your saw

when it is pinched or hung in a log.

First cut on compression side of log

BUCKING WITHOUT A SUPPORT

• Overcut through 1/3of the diameter
of the log.

• Roll the log over and finish with a
second overcut.

• Watch for logs with a compression
side to prevent the saw from pinch-

ing. See illustrations for cutting logs

with a compression side.

BUCKING USING A LOG OR
SUPPORT STAND

• Remember your first cut is always on
the compression side of the log.

LIMBING AND PRUNING

WARNING: Be alert for and

guard against kickback. Do not allow the

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

guide bar when limbing or pruning. Al-

lowing such contact can result in serious
injury.

_WARNING: Never climb into a

tree to limb or prune. Do not stand on

ladders, platforms, a log, or in any posi-

tion which can cause you to lose your

balance or control of the saw.

IMPORTANT POINTS

• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure

footing and balance.

2 nd Cut,

• Watch out for springpoles. Springpoles
are small size limbs which can catch

the saw chain and whip toward you or

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

• Be alert for springback. Watch out for
branches that are bent or under

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

in the wood fibers is released.

• Keep a clear work area. Frequently

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

LIMBING

• Always limb a tree after it is cut

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

• Leave the larger limbs underneath the

felled tree to support the tree as you
work.

• Start at the base of the felled tree and

work toward the top, cutting branches
and limbs. Remove small limbs with
one cut.

• Keep the tree between you and the

chain. Cut from the side of the tree
opposite the branch you are cutting.

• Remove larger, supporting branches

with the cutting techniques described

in BUCKING WITHOUT A SUPPORT

• Always use an overcut to cut small

and freely hanging limbs. Undercutting
could cause limbs to fall and pinch the

saw.

PRUNING

_IkWARNING: Limit pruning to limbs

shoulder height or below. Do not cut if
branches are higher than your shoulder.
Get a professional to do the job.

• Make your first cut 1/3 of the way

through the bottom of the limb.

• Next make a 2nd cut all the way

through the limb. Then cut a third
overcut leaving a 1 to 2 inch (2.5 to 5

cm) collar from the truck of the tree.

GENERAL RECOMMENDATIONS

The warranty on this unit does not cov-

er items that have been subjected to
operator abuse or negligence. To re-
ceive full value from the warranty, the
operator must maintain unit as

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

ically to properly maintain your unit.

• Once a year, replace the spark plug,
air filter, and check guide bar and

chain for wear. A new spark plug and
air filter assures proper air-fuel mixture

and helps your engine run better and
last longer.

CHECK FOR DAMAGED OR

WORN PARTS

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

NOTE: It is normal for a small amount of
oil to appear under the saw after engine
stops. Do not confuse this with a leaking

oil tank.

• ON/STOP Switch - Ensure ON/STOP
switch functions properly by moving

the switch to the STOP position. Make
sure engine stops; then restart engine

and continue.

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

jumps off the guide bar, inspect each

drive link for damage. Damaged chain
must be repaired or replaced.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A

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

ENING.
CHECK GUIDE BAR
Conditions which require guide bar

maintenance:

• Saw cuts to one side or at an angle.

• Saw has to be forced through the cut.

• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each

time chain is sharpened. A worn guide

bar will damage the chain and make
cutting difficult.

After each use, ensure ON/STOP

switch is in the STOP position, then
clean all sawdust from the guide bar

and sprocket hole.

To maintain guide bar:

• Move ON/STOP switch to STOP.

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

from saw.

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

chance of kickback which can result in
serious injury.

WAR NI N G: Wear protective

gloves when handling chain. The chain

is sharp and can cut you even when it is
not moving.

Conditions which indicate the need for

chain sharpening:

• Reduction in size of wood chips. The

size of the wood chip will decrease
as the chain gets duller until it be-
comes more like a powder than a

chip. Note that dead or rotted wood
will not produce a good chip.

• Saw cuts to one side or at an angle.

• Saw has to be forced through the cut.

Tools required:

• 5/32 inch (4 mm) diameter round file

and file holder

• Flat file

• Depth gauge tool

TO SHARPEN CHAIN:

1. Move ON/STOP switch to the STOP
position.

2. Check chain for proper tension.
Adjust chain tension if necessary.

See CHAIN TENSION section.

3. Sharpen cutters.

If your chain saw is to be stored for a
period of time:

• Clean saw thoroughly before storage.

• 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

Empty the fuel system 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.

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 3 minutes after adding stabilizer.
Craftsman 40:1,2-cycle engine oil (air
cooled) is blended with fuel stabilizer. If
you do not use this oil, you can add a

fuel stabilizer to your fuel tank.

• 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/California

Air Resources Board and Sears, Roe-

buck and Co., U.S.A., are pleased to

explain the emissions control system
warranty on your year 2007 and later
small off-road engine. In California, all
small off-road engines must be de-
signed, built, and equipped to meet the

State's stringent anti-smog standards.

Sears must warrant the emission con-
trol system on your small off-road en-

gine for the periods of time listed below

provided there has been no abuse, ne-
glect, or improper maintenance of your
small off-road engine. Your emission

control system includes parts such as
the carburetor, the ignition system and
the fuel tank (California only). Where a

warrantable condition exists, Sears will

repair your small off-road engine engine
at no cost to you. Expenses covered un-

der warranty include diagnosis, parts
and labor. MANUFACTURER'S

WARRANTY COVERAGE: If any emis-
sions 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

replaced by Sears. OWNER'S WAR-

RANTY RESPONSIBILITIES: As the
small off-road engine engine owner, you

are responsible for the performance of
the required maintenance listed in your
operator's manual. Sears recommends
that you retain all receipts covering

maintenance on your small off-road en-
gine, but Sears cannot deny warranty
solely for the lack of receipts or for your

failure to ensure the performance of all
scheduled maintenance. As the small

off-road engine engine owner, you
should be aware that Sears may deny
you warranty coverage if your small off-

road engine engine or a part of it has
failed due to abuse, neglect, improper

maintenance, unapproved modifications,
or the use of parts not made or
approved by the original equipment

manufacturer. You are responsible for

presenting your small off-road engine to

a Sears authorized repair center as
soon as a problem exists. Warranty re-
pairs should be completed in a reason-

able amount of time, not to exceed 30
days. If you have any questions regard-
ing your warranty rights and responsibili-

ties, you should contact your nearest

authorized service center or call Sears
at 1-800-469-4663. WARRANTY COM-

MENCEMENT DATE: The warranty pe-
riod begins on the date the small off-

road engine is purchased. LENGTH OF
COVERAGE: This warranty shall be for
a period of two years from the initial date
of purchase. WHAT IS COVERED: RE-

PAIR OR REPLACEMENT OF PARTS,

Repair or replacement of any warranted
part will be performed at no charge to

the owner at an approved Sears Service

Center. If you have any questions re-
garding your warranty rights and respon-
sibilities, you should contact your near-

est authorized service center or call
Sears at 1-800-469-4663. WARRANTY

PERIOD: Any warranted part which is
not scheduled for replacement as re-
quired maintenance, or which is sched-
uled only for regular inspection to the
effect of "repair or replace as necessary"
shall be warranted for 2 years. Any war-

ranted part which is scheduled for re-
placement 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 Service

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 disallowing a warranty claim. Sears

is not liable to cover failures of war-

ranted parts caused by the use of

add-on or modified parts.
