cidents. Careless or improper use of this tool can cause serious injury.

PLAN AHEAD

• Restrict the use of your saw to adult

users who understand and can fol- low the safety rules, precautions,

and operating instructions found in this manual.

Safety Shoes

• Wear protective gear. Always use

steel4oed safety footwear with non-slip soles; snug4itting clothing; heavy-duty,

non-slip gloves; eye protection such

as non4ogging, vented goggles or face screen; an approved safety hard

hat; and sound barriers (ear plugs or

mufflers) to protect your hearing. Reg- ular 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 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.

OPERATE YOUR 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 other parts im-

mediately if they become damaged, broken, or are otherwise 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 the removal 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 otherwise 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

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 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.

%_S Avoid Obstructions

Clear The Working Area

4_WARNING:Avoidkickbackwhich canresultinseriousinjury.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 re- versal 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.

• Pull4n 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.

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 running. Make sure chain

brake 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 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 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.

KICKBACK SAFETY FEATURES

_IbWARNING: The following features are included on your saw to help reduce

hazard of kickback; however, such fea- tures will not totally eliminate this danger.

Do not rely only on safety devices. Fol- low all safety rules to help avoid kick-

back 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.

• Reduced-Kickback Guide Bar: de- signed with a small radius tip which

reduces the size of the kickback dan- ger zone on the bar tip. This type bar

has been demonstrated to significantly reduce the number and seriousness of

kickbacks when tested in accordance with ANSI B175.1.

• Low*Kickback Chain: has met kick- back performance requirements when

tested on a representative sample of chain saws below 3.8 cubic inch dis-

placement specified in ANSI B175.1.

Low-Kickback Chain

CHAIN BRAKE

• Chain Brake: designed to stop the chain in the event of kickback.

dubWARNING: WE DO NOT REP- RESENT AND YOU SHOULD NOT AS-

SUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OFA

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 INTO YOUR SAW. YOUSHOULD 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 powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and jointsof people prone to

circulation disorders or abnormal swell- ing. 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 toolson a continual and regular basis must closely monitor 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 net be re-

moved or otherwise disabled to comply with Federal OSHA Regulations for

Commercial Logging.

SPARK ARRESTING SCREEN: Your saw is equipped with a temperature lim- iting muffler and spark arresting screen

which meets the requirements of Califor- nia Codes 4442 and 4443. All U.S. for-

est land and the states of California, Ida- ho, Maine, Minnesota, New Jersey,

Oregon, and Washington require by law that many internal combustion engines be equipped with a spark arresting

screen. If you operate a chain saw in a state or locale where such regulations

exist, you are legally responsible for maintaining the operating condition of

these parts. Failure to do so is a viola- tion of the law. Refer to Customer Re-

sponsibilities chart in the MAINTENANCE section.

STANDARDS: This chain saw is listed by Underwriters Laboratories, Inc. in ac-

cordance with American National Stan- dards for Gasoline-Powered Chain

Saws Safety Requirements (ANSI B175.1-2000).

_IbWARNING: Before using chain saw, ensure all fasteners are secure.

_WARNING: 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.

BEFORE STARTING ENGINE

z*L

_ILWARNING: Be sure to read the fuel handling information in the safety

rules section of this manual before you begin. If you de net understand the fuel handling information de 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. ez.).

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 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

• II),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 sym thetic oil. Mix gasoline and oil at a ratio

of 40:1. A 40:1 ratio is obtained by mix- ing 3.2 ounces of oil with 1 gallon of unleaded gasoline. Included with this

saw is a 3.2 ounce container of oil. Pour the entire contents of this con-

tainer into 1 gallon of gasoline to achieve the proper fuel mixture.

DO NOT USE automotive oil 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. 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 em

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 cleaner products in the fuel tank or permanent

damage may occun See the STORAGEsection for additional

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 disem

gaged before cutting with the saw.

zl, _____.__

8_b,WARNING: 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 con- tact with the muffler, A hot muffler can cause serious burns. STOPPING YOUR ENGINE

• 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

Flooded engines can becleared of ex- cess fuel by following the warm engine

starting procedure listed above. Insure the ON/STOPswitch is in the ON position.

Starting could require many pulls de- pending on how badly unit is flooded.

If engine still fails to start, refer to the TROUBLESHOOTING TABLE or call

1-800-235-5878.

CHAIN BRAKE

iIIWARNING: 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

0.020 inch (0.5 mm) 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 Service 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 automatically (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.

CAUTION: The chain brake must be checked several times daily. The engine must be running when performing this procedure. This is the only instance

when the saw should be placed on the ground with the engine running.

Place the saw on firm ground. Grip the rear handle with your right hand and the

front handle with your left hand. Apply full throttle by fully depressing the throttle

trigger. Activate the chain brake by turn- ing your left wrist against the hand guard

withoutreleasingyourgriparoundthe fronthandle.Thechainshouldstopim-

Inertia activating function control _WARNING: When performing the

following procedure, the engine must be turned off.

Grip the rear handle with your right hand and the front handle with your left hand.

Hold the chain saw approximately 14 inches (35 cm) above a stump or other

wooden surface. Release your grip on the front handle and let the tip of the

guide bar fall forward and contact the stump. When the tip of the bar hits the

stump, the brake should activate. OPERATING TIPS

• Check chain tension before first use and after 1 minute of operation. See

CHAIN TENSION in the MAINTENANCE section.

• Cut wood only. De not cut metal, plastics, masonry, non-weed building

materials, etc.

• Stop the saw if the chain strikes a 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 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. 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, If the tree does make con- tact with any utility line, the utility com-

pany should be notified 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 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 clear retreat path

;t.... U--""""_- Direction of fali

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 1/3of 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 tree.

Notch _

_ge

• 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

Opening of felling cut

Closinq 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.

• DQ 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.

TYPES OF CUTTING USED FOR BUCKING

Z_ d_II_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, 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.

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.

zl, _____.__

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

concentrated.

BUCKING WITHOUT A SUPPORT

• Overcut through I/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 illustrations 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 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 mov-

ing chain to contact any other branches or objects at the nose of the guide bar

when limbing or pruning. Allowing such contact can result in serious injury.

_IbWARNING: 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 caution when cutting

small size limbs.

• Be alert for springback from any

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.

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 instruct- ed in this manual. Various adjustments

will need to be made periodically to properly maintain your unit.

• Once a year, replace the spark plug, air filter element, and check guide bar

and chain for wear. A new spark plug and air filter element assures proper

air-fuel mixture and helps your engine run better and last longer.

CHECK FOR DAMAGED OR WORN PARTS Contact Sears Service Center for re-

placement of damaged or worn parts. NOTE: It is normal for a small amount

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.

• 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 CHAIN TENSION _IlbWARNING: 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 es- pecially true during the first few times

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.

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 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.

41bWARNING: If the saw is operated with a loose chain, the chain could

jump off the guide bar and result in se-

rious injury.
