• 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.

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 wellventilated 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 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 projecting be hind you; guide bar preferably cov ered with a scabbard.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service performed by a qualified service dealer except the items listed in the maintenance section of this manual.

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

leased. For correction, refer to “Car buretor Adjustments.”

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

• Biminate 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 re- move fuel cap and refuel unit.

• Store the unit and fuel in a cool, dry well ventilated space where fuei 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.

WARNING: Rotational Kickback cari 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 Is a 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. Wifri a basic understanding of kickback, you can reduce the element of suiprise which contributes to 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 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 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 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 fail into chain.

» Use the specified Reduced-Kickback

Guide Bar and Low-Kickback Chain.

Avoid Pirich-Ktckback:

• 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 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

Thumb on underside of handlebar]

keep your body from being in a direct line with the cutting chain.

• Stand with your weight evenly bal anced on both feet,

• Do not overreach. You could be drawn or thrown off balance and lose control.

• 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 kici^ack; however, such fea tures will not totally eliminate this dan ger. Do not rely only on safety devices.

• Handguard: designed to reduce the

chance of your feft hand contacting the chain if your hand slips off the

front handleb^.

• 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 controiling 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. This type bar has been

demonstrated to significantly reduce

the number and seriousness of kick

backs when tested in accordance with

ANSI B175.1.

BEFORE STARTING ENGINE

WARNING: Be $ure to read the fuel handling infonnation in the safety rules section of this manual before you begin. If you do not understand the fuel han

dling information do not attempt to fuel your unit. Seek help from someone that does understand the information or call the customer assistance help line at

1-800-235-5878. GUIDE BAR AND CHAIN OIL

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 fl. 02.). For maximum guide bar and chain life,

we recommend you use Craftsman chain saw bar oil. If Craftsman bar oil is not available, you may use a good grade SAE 30 oil until you are able to

obtain Craftsman brand. The oil output is automatically metered during opera tion. Your saw will use approximately one tank of bar oi! 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 oil. We recommend Craftsman brand oil. Mix ' gasoline oil at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 '

ounces of oil with 1 gallon of unleaded gasoline). DO NOT USE automotive oil or boat oil. These oils will cause engine

damage. When mixing fuel follow 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

relating to fuel before fueling your unit.

flooded. If engine still fails to start, re ferió the TROUBLESHOOTING chart or call 1-800-235-5878.

OPERATING TIPS

• Check chain tension before first use and after 1 minute of operation. See Chain Tension in the Mainienance

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 dirt will 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 “feel" of using your saw before

you begin a major sawing operation.

• Squeeze the throttle trigger and al low the engine to reach kill 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 compfeied, allowing the engine to idfe. If you run the saw at

full throttle without a cutting load, unnecessary wear can occur.

• 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 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.

• Study the natural conditions that can

cause the tree to fail 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.

Plan a dear retreat path

45*

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 fail In the direction of the notch.

NOTE: If tree has large buttress roots,

remove them before making the notch.

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.

' 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 will leave enough uncut wood between the fell

ing cut and the notch to form a hinge.

► - Direction of Fall

This hinge will help prevent the tree

from falling in the wrong direction.

Hinge holds free on stump and helps control fall

Opening of felling cut

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, widening of the felling cut, or movement in the up per branches.

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

» Be extremely cautious with partially

fallen trees that may be poorly sup ported. When a tree doesn’t fall com pletely, set the saw aside and puJI 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 (BUCKING) Bucking is the term used for cutting a

fallen tree to the desired fog size. WARNING: Do not stand on the log

being cut. Any portion can roll causing loss of footing and control. Do not starid 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 iog with your leg or foot.

• Do not cut in art area vrfiere logs, limbs, and roots are tangled. Drag Icigs into a clear area before cutting them.

BUCKING TECHNIQUES WARNING: if saw becomes pinched or hung in a log, don’t fry 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

or wood Wo the cut until the saw can be removed easily. Restart saw and carefully

reenter the cut. 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 out open.

Overcutting begins on the top side of the log with the bottom of the saw against the log. When overcufting use light downward pressure.

Overcutting 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. WARNING: Never turn saw upside

down to undercut. The saw cannot be controlled in this position.

LIMBING AND PRUNING

WARNING: Never climb into a tree to limb or prune. Do not stand on ladders,

platforms, a fog, or in any position which can cause you to lose your bal ance or control of the saw.

IMPORTANT POINTS

• Watch out for springpoles.

Springpoies are small size limbs which can whip toward you, or pull you off balance. Use extreme caution when cutting small size limbs.

• Be alert for springback. Watch out for branches that are bent or under pres sure. 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 orre cut.

• Keep the tree between you and the chain.

• Remove larger, supporting branches with the 1/3,2/3 cutting techniques de scribed in the bucking section.

• Always use an overcut to cut small and freely hanging limbs. Undercut ting couid cause limbs to fall and pinch the saw.
