Wear protective gear. Always use steel-toed safety footwear with non-

slip 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 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 ifyou are felling a tree, a retreat path.

OPERATEYOURSAWSAFELY

• 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 welt- 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 at the

end of the cut. Applying pressure can cause you to lose control when the

cut is completed.

• Stop the engine before setting the

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

WOR KING ORDER

• Have allchain saw service performed bya qualifiedservice dealer except

the itemslisted inthemaintenance

section ofthismanual.

° Make certainthesaw chainstops

buretor Adjustments."

° Keepthe handlesdry,clean,andfree

from oil orfuel mi_ure.

• Keep capsand fasteners securely

tightened.

• Use onlyCraftsmanaccessoriesand replacementpartsas recommended.

Never modify yoursaw.

HANDLE FUEL WITH CAUTION

° Do not smoke while handling fuel or

while operating the saw.

• Eliminate all sources of sparks or flame in the 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 fuel va- pors cannot reach sparks or open

flames from water heaters, electric motors or switches, furnaces, etc.

GUARD AGAINST KICKBACK

WARNING: 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 is a lightning fast, reverse reaction which kicks the guide bar up

and back toward the operator.

_,_ _ KickbackPath

Avoid Obstructions

CIearThe WorkingArea

Pinch-Kickback and Pull-tn 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 understanding of kick- back, you can reduce the element of

surprise which contributesto acci- dents.

SAFETYNOTICE: Exposure to vibrations through prolonged use of

gasoline powered hand tools could cause blood vessel or nerve damage in

the fingers, hands, and joints ofpeople prone to circulation disorders or

abnormal swelling. 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-vibration system does not guarantee the avoidance of these

problems. Users who operate power tools on a continual and regular basis must closely monitor their physica!

condition and the condilion of this tool. CHAIN BRAKE If this saw is to be used

for commercial logging, you must order and installa chain brake to comply with Federal OSHA Regulations for Com- mercial Logging. Contact your Sears

GUIDE BAR AND CHAIN OIL

The chainoiler providescontinuouslu- bricationto the chain andguidebar. Be

sure tofillthe bar oiltankwhenyou fill

the fuel tank(Capacity= 6.8 fl. oz.)

Formaximumguidebar andchainlife, we recommendyouuseCraftsman

chainsaw bar oil. IfCraftsmanbar oil is not available,you may usea good

gradeSAE 30 oil untilyouareableto obtainCraftsmanbrand.The oiloutput

is automaticallymetered during opera- tion. Your saw will use approximately one tank of bar oil for every tank of fuel mix.Always fill the bar oiltank when

you fill the fueltank.

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 oi!. Mix

gasoline and 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 wilt 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.

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. Acid-

ic 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 run until

the fuel lines and carburetor are empty.

Use fresh fuel next season.See STOR-

AGEinstructionsfor additionalinforma-

tion. Neveruseengineor carburetorcleaner

OPERATING TIPS

• Check chain tension before first use

and after 1 minute 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 dirt will quick- ly dull a chain and increase the possi-

bitity 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 throttletrigger and al-

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. tfyou run the saw at

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

• To avoid losingcontrol when cut is complete, do not put pressure on

saw at end of cut.

• Stop the engine before setting the 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 nightsince you will notbe able to see

well, nor during bad weather such as

rain, snow, orstrong 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 fall in a particular direction, such conditions include:

• The wind direction and speed.

• The lean of the tree. The lean of a

tree might not be apparent due to un-

even or sloping terrain. Use a plumb

or level to determine tile direction 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-I/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.

This hinge wilt help prevent the tree from falling in the wrong direction.

.... O"_ - Directionof Fall

FELUNG 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 inthe desired direction of fall. After

a felling cut is made on the opposite

side oftree, the tree should fall in the

direction of the notch. NOTE: If the 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 1/3of 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 the

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.

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 of 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 pull

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 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 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 fool

• Do not cut in an area where logs,

limbs, and roots are tangled. Drag the logs into a clear area before cutting

them.

BUCKING TECHNIQUES

WARNING: tfsaw becomes pinched or hung in a log, don't try to force it ouL

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 into the cut until the saw can

be removed easily, Restart the 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.
