• Wear protective gear. Always use

steel-toed safety footwear with non-
slip soles; snug-fitting clothing;

heavy-duty, non-slip gloves; eye pro-

tection such as non-fogging, vented
goggles or face screen; an approved

safety hard hat; and sound barriers
(ear plugs or mufflers) to protect your
hearing. Regular users should have
hearing checked regularly as chain
saw noise can damage hearing.

• Secure hair above shoulder length.
Do not wear loose clothing or jewelry;
they can get caught in moving 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 up-
set, or if you have taken alcohol,

drugs, or medication. You must be in
good physical condition and mentally
alert. If you have any condition that
might be aggravated by strenuous
work, check with doctor before oper-
ating.

• Do not start cutting until you have a
clear work area, secure footing, and

especially if you are felling a tree, a
retreat path.

2

OPERATEYOUR SAW SAFELY

• Do not operate with one hand. Seri-
ous injury to the operator, helpers, or

bystanders may result from one-
handed operation. A chain saw is in-

tended for two-handed use.

• Operate the chain saw only in a well-
ventilated outdoor area.

• Do not operate saw from a ladder or

in a tree.

• Make sure the chain will not make
contact with any object while starting

the engine. Never try to start the saw
when the guide bar is in a cut.

• Do not put pressure on the saw, es-

pecially at the end of the cut. Doing
so can cause you to lose control
when the cut is completed.

• Stop engine before setting saw
down.

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

from body; guide bar& chain project-

ing behind you; guide bar preferably

covered with a scabbard.

• Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
Always replace bar, chain, hand

guard, chain brake, or o_er parts im-

mediately if hey become damaged,
broken, or are ogqerwise 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 _qeremoval 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 o_qerwise 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
al! 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.

, Avoid Obstructions

/ "J

Clear The Working Area

z& _____°_=

_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 sudden stopping of the chain

results in a reversal of the chain
force used to cut wood and causes

the saw to move in the opposite di-
rection of the chain rotation. The

saw is driven straight back toward
the operaton

Pull-In can occur when the moving
chain contacts a foreign object in

the wood in the cut along the bot-
tom of the guide bar and the saw
chain is suddenly stopped. This

sudden stopping pulls the saw for-
ward and away from the operator
and could easily cause the opera-
tor to lose control of the saw.

REDUCE THE CHANCE OF
KICKBACK

• Recognize that kickback can happen.
With a basic understanding of kick-

back, you can reduce the element of

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 rdnning. 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. 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

IIWAI_NINIJ: 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 ofthese 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 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. Do not

rely exclusively upon safety devices
built into your saw.

SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gasoline

_IbWARNING: 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 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 oi!

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

zIL __=____=

*!I_WARNING: Remove fuel cap

slowly when refueling.
This engine is certified to operate on un-

leaded gasoline. Before operation, gaso-

line must be mixed with a good quality

synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand syn-
thetic oil. Mix gasoline and oil at a ratio

of 40:1. A 40:1 ratio is obtained by mix-

ing 3.2 ounces ofoil with 1 gallon of

unleaded gasoline. Included with this

saw is a 3.2 ounce container of Crafts-

man brand synthetic oil. Pour the en-
tire contents of this container into 1

gallon of gasoline to achieve the prop-

er fuel mixture.

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

When mixing fuel, follow instructions

printed on the oil containen

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.

zIL _____ __ =

_WARNING: The chain must not
move when the engine runs at idle

speed. If the chain moves at idle

CHAIN BRAKE
_IbWARNING: 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 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 automaticaily (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.

OPERATINGTIPS

• Checkchaintensionbeforefirstuse
andafter1minuteofoperation.See

CHAINTENSIONintheMAINTENANCE
section.

• Cutwoodonly.Donotcutmetal,

plastics,masonry,non-woodbuilding
materials,etc.

•Stopthesawifthechainstrikesa

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 a!-
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 the chain, bar and engine. It is
recommended that the engine
not be operated for longer than

30 seconds at full throttle.

• 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

X1= _

_!_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.

• 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.

_,-"- - £)"_ - 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

Felling cut here

Hinge

• After removing the wood from the

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

by making a cut about two inches
higher than the center of the notch.

This will leave enough uncut wood

between the felling cut and the notch

to form a hinge. This hinge will help

prevent the tree from falling in the

wrong direction.

Hinge holds tree on
stump and helps
control fall

Closing
of notch

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.
_I_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.

SUCKING TECHNIQUES

_WARNING: Ifsaw becomes

pinched or hung in a log, don't try to
force it out. You can lose control of the

saw resulting in injury and/or damage
to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut
until the saw can be removed easily. Re-

start saw and carefully reenter the cut.

Do not use a metal wedge. Do not at-
tempt to restart your saw when it is
pinched or hung in a log.

Use 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.

11

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.

_IkWARNING: 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 Iog is where the pres-
sure of the log's weight is

concentrated.

First cut on compression side of log

Second cut

Firstcut on compression side of log

BUCKING WITHOUT A SUPPORT

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

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

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

ing. See ilIustration above for cut-

ting logs with a compression side.

BUCKING USING A LOG OR
SUPPORT STAND

• Remember your first cut is always on
the compression side of the log. (Re-
fer to the illustration below for your
first and second cut).

• Your first cut should extend 1/3 of the
diameter of the log.

• Finish with your second cut.

LIMBING AND PRUNING

z_ ___=_=_=

_I),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 seri-
ous injury.

_kWARNING: 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.

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.

12

• 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 fail and

pinch the saw.

PRUNING

_II_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.

_1_ WARNING: Disconnect the spark plug before performing maintenance

except for carburetor adjustments.

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 especially true during the first
fewtimes 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.

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 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 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.

14

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 operafion.

Remove Sawdust From

__l_Guide Bar Groove

• Add lubricant to sprocket hole after

each use.

• Burring of guide bar rails is a normal
process of rai! wear. Remove these
burrs with a fiat file.

• When rail top is uneven, use a fiat file

to restore square edges and sides.

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 reinstal-
ling.

5. Lighfiy 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
