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

if you are felling trees, a planned re-

treat path.

OPERATE YOUR SAW SAFELY

• Do not operate a chain saw with one

hand. Serious injury to the operator, helpers, bystanders or any combina-

tion of these persons may result from one-handed operation. A chain saw

is intended 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 at the end of the cut. Applying pressure 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 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

_/L WARNING: 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.

GUARDAGAINSTKICKBACK Followallsafetyrulestohelpavoid

kickbackandotherforceswhichcan resultinseriousinjury.

"_\ ¢__;: Kickback Path

,_/LWARNING: 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.

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

Stand to the left of the saw

underside t

Thumb on \[

"1 /S

r \\

Elbow locked

Never reverse hand positions

• 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 when making bucking cuts. Never reverse right and left hand

positions for any type of cutting.

• Stand with your weight evenly bal-

anced on both feet.

• Do not overreach. You could be

drawn or thrown off balance and lose control of the saw.

• Do not cut above shoulder height. It is difficult to maintain control of saw

above shoulder height.

KICKBACK SAFETY FEATURES

_ILWARNING: 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.

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 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 INTOYOUR SAW. YOU SHOULD USETHE 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

chain brake should be made by an au-

thorized Sears Service Center. Take

your unit to the place of purchase if purchased from a servicing dealer, 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 devices built into

your saw.

This unit is not equipped with an anti- vibration system and is intended for

occasional use only. 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-

ings. 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- bration system does not guarantee the

avoidance of these problems. Users who operate power tools on a continual and regular basis must monitor closely

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 com- ply with Federal OSHA Regulations for

ing the CHOKE/FAST IDLE LEVER out to the full extent for cold starting or after refueling. The choke provides additional

fuel to the engine during cold starting.

PRIMER BULB The PRIMER BULB circulates fuel to the

carburetor to provide quicker starting.

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 off the guide bar and result

in serious injury to the operator and/or damage the chain making it unusable.

BEFORE STARTING ENGINE _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.

_LWARNING: 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 fl. 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

_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 at a ratio of 40:1. A 40:1 ratio is ob-

tained by mixing 3.2 fluid ounces of oil

with 1 gallon of unleaded gasoline. In- cluded with this saw is a 3.2 ounce con-

tainer of oil. Pour the entire contents of this container 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. Always

read and follow the safety rules relat- ing to fuel before fueling your unit. CAUTION: Never use straight gasoline in your unit. This will cause permanent engine damage and void the limited warranty.

FUELREQUIREMENTS Thisenginerequirestheuseof

minimum87octane[R+M]/2clean gasoline.

IMPORTANT

Useofalcoholblendedfuels(called gasoholorusingethanolormethanol) cancausemajorengineperformance

anddurabilityproblems.

_/L WARNING: Alternative fuels (not gasoline) such as E-15 (15% alcohol),

E-20 (20% alcohol), E-85 (85% alcohol) are NOTclassified as gasoline and are

NOTapproved for use in 2-stroke gaso-

line engines. Use of alternative fuels will cause problems such as: improper

clutch engagements, overheating, vapor

lock, power loss, lubrication deficiency, deterioration of fuel lines, gaskets and

internal carburetor components, etc. Al- ternative fuels cause high moisture ab- sorption into the fuel/oil mixture leading

to oil and fuel separation.

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.

_ILWARNING: 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.

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 ofthe 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. Ifthe 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.

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.

Second.

• 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

Opening

Closing of notch

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. _IkWARNING: 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.

TYPES OF CUTTING USED FOR

BUCKING

_/L 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.

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.

.%_O,,vercutting

Undercutting '- ,.,_

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.

_/LWARNING: Neverturn 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.

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.

(Refer to the illustrations below for

your first and second cut)

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

• Finish with your second cut.

LIMBING AND PRUNING

_,WARNING: Be alert for and

guard against kickback. Do not allow the 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.

• 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.

shoulder height or below. Do not cut if branches are higher than your shoulder.

Get a )rofessional to do the job.

• Make your first cut 1/3of 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.

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

CHECK FOR LOOSE FASTENERS AND PARTS

• Bar Nuts

• Chain

• Muffler

• Cylinder Shield

• Air Filter

• Handle Screws

• Vibration Mounts

• Starter Housing

• Front Hand Guard

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 especially true during the first few times you use your

saw. Always check chain tension each time before you start the chain 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.

7. Use the screwdriver end of the bar tool to move chain around guide bar.

8. If chain does not rotate, it is too tight. Slightly loosen bar nuts and

loosen chain by turning the adjust- ing screw 1/4turn counterclock-

wise. Retighten bar 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.

NOTE: The chain is tensioned correctly when the weight of the chain does not

cause it to sag below the guide bar
