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 headng. Reg-
ular users should have hearing
checked regularly as chain saw noise
can damage headng.

• 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 pads im-

mediately if they become damaged,
broken, or are otherwise removed.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service per-
formed by a qualified service dealer
except the items listed in the MAiNTE-

NANCE section of this manual.

• Make certain the saw chain stops

moving when the throttle trigger is
released. For correction, refer to

CARBURETOR ADJUSTMENTS.

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

• Keep caps and fasteners securely
tightened.

• Nonconforming replacement compo-

nents or the removal of safety devices
may cause damage to the unit and

possible injury to the operator or by-
standers. Use only Craftsman <'_acces-
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 propedy and perform its
intended function. Check for alignment
of moving parts, binding of moving

parts, breakage of pads, mounting and
any other conditions that may affect its
operation. A guard or other part that is
damaged should be propedy 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

Avoid Obstructions

Clear The Working Area

zt _

41_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.

• Pull4n 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 dullchain 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. Ifthe 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 Pull4n:

• 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. Gdp 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

KICKBACK SAFETY FEATURES

_WARN|NG: 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
_nsenous _njury,

• 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 "inqine" 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.

aWARNINu: wEDONOTREP-
RESENTAND 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 tow-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-

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

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. De 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
occur such as numbness, pain, loss of

strength, change in skin color or texture,

or loss of feeling in the fingers, hands, or
joints, discontinue the use of this tool

and seek medical attention. An anti-vi-
brafion system does not guarantee the
avoidance of these problems. Users

who operate power tools on a continual

and regular basis must closely monitor

their physical condition and the condition
of this tool.

CHAIN BRAKE: If this saw is to be
used for commercial logging, a chain

brake is required and shall not be re-
moved or otherwise disabled to comply

with Federal OSHA Regulations for

Commercial Logging.

SPARK ARRESTING SCREEN: Your
saw is equipped with a temperature lim-

iting muffler and spark arresting screen
which meets the requirements of Califor-

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

section.

aWARNING: 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 lubdcation.
The chain oiler provides continuous lu-

brication to the chain and guide bar Be

sure to fill the bar oil tank when you fill
the fuel tank (Capacity = 6.8 fi. 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 operation.

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

£A _

aWARNING: Remove fuel cap

slowly when refueling.
This engine is certified to operate on

unleaded gasoline. Before operation,
gasoline must be mixed with a good

quality synthetic 2-cycle air-cooled en-
gine oil We recommend Craftsman

brand synthetic oil. Mix gasoline and
oil at a ratio of 40:1. A 40:1 ratio is ob-

tained by mixing 3.2 ounces ofoil with

1 gallon of unleaded gasoline. In-

cluded with this saw is a 3.2 ounce

container of Craftsman brand synthetic
oil. Pour the entire contents of this con-

tainer into 1 gallon of gasoline to

achieve the proper fuel mixture.

DO NOT USE automotive oil or marine
oil. These oils will cause engine dam-

age. When mixing fuel, follow 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

Expedenca 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.

41_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

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
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.

;t""" "O" "_ - Direction of fall

FELLING LARGE TREES

(6 inches in diameter or larger)

The notch method is used to fell large
trees. A notch is cut on the side of the

tree in the desired direction of fall. After

a felling cut is made on the opposite
side of tree, the tree will tend to fall in

the direction of the notch.

NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting

ground to prevent dulling of the chain.

NOTCH CUT AND FELLING TREE

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

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

illustration. Once the notch is cut, re-
move the wedge of wood from tree.

First cut 2.I

• After removing the wood from the

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

by making a cut about two inches
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.

stump and helps

control fall

Opening of

Closin
of not_

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 A FALLEN TREE
(BUCKING)

Bucking is the term used for cutting a
fallen tree to the desired log size.

zt _

41_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.

TYPES OF CUTTING USED FOR
BUCKING

_WARNING: If saw becomes
pinched or hung in a log, don't try to

force it out. You can lose control of the
saw resulting in injury and/or damage
to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut
until the saw can be removed easily. 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.

11

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 overcutfing use
light downward pressure.

• Finish with your second cut.

Overcutting _

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

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 illustration above for cut-

fing 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 1/3of the
diameter of the log,

LIMBING AND PRUNING

£A _

4mWARNING: 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 limb or prune. Do not stand on

ladders, platforms, a log, or in any po-
sition which can cause you to lose
your balance or control of the saw.

IMPORTANT POINTS

• Watch out for springpoles.
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.

_X>, _-

12

LIMBING

• Limb a tree only after it is cut down.

• Leave the larger limbs underneath
the felled tree to support the tree as

you work.

• Start at the base of the felled tree
and work toward the top, cutting

branches and limbs. Remove small
limbs with one cut.

• Keep the tree between you and the
chain.

• Remove larger branches with the
cutting techniques described in

BUCKING WITHOUT A SUPPORT.

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

ting could cause limbs to fall and

pinch the saw.

PRUNING

_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.

ceive full value from the warranty, the

• 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

_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.

I_WARNING: If the saw is operated
with a loose chain, the chain could

jump off the guide bar and result in se-

rious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A

dull chain makes a sawdust powder
and cuts slowly, See CHAIN SHARP-
ENING in the SERVICE AND ADJUST-

MENTS section.
CHECK GUIDE BAR

Conditions which require guide bar
maintenance:

• Saw cuts to one side or at an angle.

• Saw has to be forced _rough the cut.

• Inadequate supply ofoil to bar/chain.

Check the condition of guide bar each
time chain is sharpened, A worn guide

14

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.

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 airfilter.

4. Clean the air filter using hot soapy

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

5. Lightly oil air filter before installing

to improve the efficiency of air filter.

Use 2-cycle engine oil or motor oil

(SAE 30). Squeeze excess oil from
filter.

6. Reinstall airfilter.

7. Reinstall cylinder cover and 3

screws. Tighten securely.
