• Wear protective gear. Always use

steel-toed safety footwear with non-

s!ip 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

ptugs or mufflers) to protect your

hearing. Regular users should have

hearing checked regularly as chain

saw noise can damage hearing. Se-

cure hair above shoulder length.

• 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 sew

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

ctear work area, secure footing, and

especially ifyou are felling a tree, a

retreat path.

OPERATEYOUR SAW SAFELY

• Do not operate with one hand. Seri-

ous injuryto the operator, helpers, or

bystanders may result from one-

handed operation. A chain saw is in-

tended for &vo-handed use.

• Operate the chain saw only in a well-

ventilated outdoor area.

• Do not operate saw from a ladder or

in a tree, unless you are specifically

trained to do so.

• 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 Iose control

when the cut is completed.

• Stop engine before setting saw down.

• Hand carry saw onty when engine is

stopped. Carry with muffler away from

body; guide bar & chain projecting be-

hind you; guide bar preferably cow

ered with a scabbard.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service performed

by a quatified service dealer except

the items listed in the maintenance

section of this manual

• Make certain the saw chain stops

moving when the throtIle trigger is re-

leased. For correction, refer to "Car-

buretor Adjustments.*

• Keep the handles dry,clean, and free

from oi_or fuel mixture.

• Keep caps and fasteners securely

tightened.

• Use only Craftsman accessories and

replacement parts as recommended.

Never modify your saw.

HANDLE FUEL WITH CAUTION

• Do not smoke while handling fuel or

while operating the saw.

° Eliminate al! 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°combustibJe area, not on dry

leaves, straw, paper, etc. SIowty re-

move 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.

"_ _ KickbackPath

AvoidObstructions

ClearThe WorkingArea

WAR NIN G' Rotational Kickback can

occur when the moving chain contacts

an object at the upper portion of the tip

of the guide bar. Contact at the upper

portion of the tip of the guide bar can

cause the chain to dig into the object,

which stops the chain for an instant. The

result isa lightning fast, reverse reaction

which kicks the guide bar up and back

toward the operator.

Pinch-Kickback and Pull-in occur when

the chain is suddenly stopped by being

pinched, caught, or by contacting a for-

eign object in the wood. This sudden

stopping of the chain results in a rever-

sal of the chain force used to cut wood

and causes the saw to move in the op-

posite direction of the chain rotation.

Pinch-Kickback drives the saw straight

back toward the operator, Pull-In pulls

the saw away from the operator.

REDUCE THE CHANCE OF

KICKBACK

• Recognize that kickback can happen.

With a basic understat_ding of kickback,

you can reduce the element of surprise

which contributesto accidents.

• 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.

• Keep saw chain sharp and prdperly

tensioned, A loose or dull chain can

increasethechanceofkickback.FoF

lowmanufacturer'schainsharpening

and maintenance instructions. Check

tension at regular intervals, but never

with engine running, Make sure bar

clamp 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

acut.

Do not attempt cuts starting with the

i 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 tog at a

time.

• Do not twist saw as bar is withdrawn

from an undercut when bucking.

Avoid Pull-In:

• Always begin cutting with the eng!ne

at fult speed and the saw housing

ag2inst wood.

• Use wedges made of p/astie or wood,

Never use metal to hold the cut open.

• Do not cut above shoulder height, It is

difficult to maintain control of saw

above shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features are

included on your saw to help reduce

hazard of kickback; however, such fea-

tures wi/l not totally etiminate this dan-

ger. Do not rely only or_safety devices.

• Handguard: designed to reduce the

chance of your left hand contacting

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 controllingthe pivot of the

saw back toward the operator If kick-

back occurs,

• Reduced-Kickback Guide Bar: de-

signed with a smal! radius tip which

reduces the size of the kickback dan-

ger zone, This type bar has been

demonstrated to significantly reduce

the number and seriousness of kick-

backs when tested in accordance with

GUIDE BAR AND CHAIN OIL

The chain citer 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 fl, oz.).

For maximum guide bar and chain life,

we recommend you use Craftsman

chain saw bar oil. if Craftsman bar oil is

net 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

This engine is certified to operate on

unleaded gasoline, Before operation,

gasoline must be mixed with a good

quality 2-cycle air-cooled engine 0il. 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 1gallon of unleaded

gasoline). DO NOT USEautomotive oil

or boat oil. These oils will cause engine

damage. When mixing fuel foltow the

instructions printed on the container,

Once oil is added to the gasoline,

shake container momentarily to assure

that the fuel is thoroughly mixed.

Always read and follow the safety rules

reiating to fuel before fueling your unit.

IMPORTANT

Experience indicates thatalcoho_blended

fuels (calted gasohof or using ethanol or

methanol) can attract moisture 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 sys-

tem should be emptied before storage for

30 days or longer. Drain the gas tank,

start the engine and let it rununtit the fuel

lines and carburetor are empty. Use fresh

fuel next season. See STORAGEinstruc-

tions for addltJonalinformation.

Never use engine orcarburetor c_eaner

products in the fuel tank or permanent

damage may occur.

See the STORAGEsection for addit{onal

information.

OPERATING TIPS

- Check chain tension before first use

and after 1minute of operation. See

Chain Tension in the Maintenance

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 for-

eign object, inspect the saw and re-

pair parts as necessary.

. Keep the chain out of dirt and sand.

Even a small amount of dirtwill quick-

ly dull a chain and increase the possi-

bility of kickback.

• Practice cutting a few small logs using

the following steps. This will help you

get the ffeeI" 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 cuttingwith the saw frame

against the tog.

Keep the engine at full speed the

i entire you are cutting.

time

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 cuttingload,

unnecessary wear can occur.

• To avoid losing oontrot when cut is

complete, do not put pressure on

sat,' at end of cut.

, Stop engine before settingsaw down.

TREE FELLING TECHNIQUES

WARNING: Check for broken or dead

branches which can fall white cutting

causing serious injury. Do not cut near

buildings or electrical wires if you do not

knowthe 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 th_ tree so you can

have secure footing.

• 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

FELLING LARGE TREES

(6 inches in diameter or larger)

The notch method is used to feII large

trees, A notch is cut on the side of the

tree in the desired direction of fall. After

a feliing cut is made on the opposite

side of tree, the tree will tend to fall in

the direction of the notch.

NOTE: tf tree has large buttress roots,

remove them before making the notch.

NOTCH OUT AND FELLING TREE

• Make notch cut by cutting the top of

the notch first, Cut through 1/3 of the

diameter ofthe tree. Next complete

the notch by cutting the bottom. See

illustration. Once the notch is cut, re-

move the wedge ofwood from tree.

Fina!cuthere

. After removing the wood, make the

felling cut on the opposite side of the

notch, This is done by making a cut

about two inches higher than the cen-

ter of the notch. This wiil leave

enough uncut wood between the felt-

ing cut and the notch to form a hinge.

This hinge will help prevent the tree

in the wrong direction.

Opening of

felling cut

NOTE: Before felling cut iscomplete,

use wedges to open the cut when

necessary to control the direction of fall,

To avoid kickback and chain damage,

use wood or ptastic wedges, but never

steel or iron wedges.

• Be alert to signs that the tree is ready

to fall: cracking sounds, widening of

the fetiing cut, or movement in the up-

per branches,

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

down, arid get away quickly on your

planned retreat path.

• Be extremely cautioL_swith partially

fallen trees that may be poorly sup-

ported. When a tree doesn't fall com-

pletely, set the saw aside and pult

down the tree with a cable winch,

block and tackle, or tractor, Do not

use your saw to cut down a partially

fallen tree,

CUTTING A FALLEN TREE

BBUCKING)

ucking 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 tog 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 altow another person to hold

the log while cuttingand 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.

BUCKING TECHNIQUES

WARNING: Ifsaw becomes pinched

or hung in a log, don't try to force it out.

You can lose control of the saw result-

ing in injury and/or damage to the saw.

Stop the saw, drive a wedge of plastic

orwood into the cut until the saw can be

removed easily. Restart saw end carefully

of oil to appear under the saw after en-

gine stops. Do not confuse this with a

leaking oil tank.

• On!Stop Switch - Ensure On/Stop

switch functions properly by moving

the switch to the "Stop" position.

Make sure engine stops; then restart

engine and continue.

o Fuet Tank - Do not use saw if fuel

and cuts slowly.

CHAIN SHARPENING

Chain sharpening requires special

tools. You can purchase sharpening

tools at Sears or go to a professional

chain sharpener.

CHECK GUIDE BAR

Conditions which require guide bar

maTntenanee:

• Saw cuts to one side or at an angle

• Saw has to be forced through the cut

° Inadequate supply of oil to bar/chain

CLEAN FUEL FILTER

To clean fuel filter, drain your unit by

running dry of fuel, remove fuel cap!re-

tainer assembly from tank. Pult filter

from tank and remove from line. Clean

with mild detergent and rinse. Dry thor-

oughly, reassemble.

CARBURETOR ADJUSTMENT

WARNING: The chain will be moving

during most of this procedure. Wear

your protective equipment and observe

alf 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 criticaland 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.

Otd fuel, a dirty air tilter, dirty fuel filter,

or flooding may give the impression of

an improperly adjusted carburetor.

Check these conditions before adjust-

ing the carburetor.

The carburetor has been carefully set at

the factory, Adjustments may be neces-

sary if you notice any of the following

conditions:

• Chain moves at idle. See "Idle Speed"

under adjusting procedure.

• Saw will not idle, See "Idle Speed"

and "Low Speed Mixture"under, ad-

justing procedure.

° Engine dies or hesitates when it

should accelerate. See "Acceleration

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 ToThey are located in the area }ust

above the pdmer bulb.

CARBURETOR PRESETS

When making adjustments, do not force

the plastic limiter caps beyond the

stops or damage will occur.

If carburetor presets are not needed,

proceed to "idle Speed-T."

. Turn both mixture screws counter-

clockwise until they stop.

• Turn the idle speed screw clockwise

until it stops. Now turn counterclock-

wise 4.1/2 full turns.

Start motor, let it run for 3 minutes, and

proceed to the adjustment section. If

engine does not start, refer to trouble-

shooting chart or call 1-800-235-5878.

If engine performance is acceptable at

the preset positions and there _sno

chain movement at idle, no further ad-

justment is necessary.

ADJUSTING PROCEDURE

Idle Speed-T

Allow engine to idle, Adjust speed until

engine runs without chain movement or

stalling,

• Turn clockwise to increase engine

speed if engine staIIs or dies.

• Turn counterclockwise to decrease

speed.

No further adjustments are necessary if

chain does not move at idle speed and

if performance is satisfactory.

Low Speed Mixture-I.

Allow engine to idle. Then accelerate

the engine and note performance. If en-

gine hesitates, bogs down, or smokes

during acceleration, turn mixture screw

clockwise in 1/16-turn increments until

performance issatisfactory, Repeat this

procedure as necessa_i for proper ad-

justment. After completIng adjustments,

check for acceleration and chain move-

ment at idle. Reset if necessary.

High Speed Mixture-H

DO NOT operate engine at full throttle

for prolonged periods while mak;ng ad-

justments. Damage to the engine can

occur. Make a test out. Based on per-

formance of the saw while cutting, ad-

just the high speed mixture setting in

1/16-turn increments as fol]o,,vs:

• Clockwise until saw has good power in

the cut with no hesitation. Do not adjust

by sound or speed, but judge by how

well the saw performs in the cut.

° 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 Iow speed mixture

adjustment counterclockwise until you

have smooth acceleration with no chain

.movement at idle. Recheck and adjust as

necessary for acceptable performance.
