• Wear protective gear. Always use

steel-toed safety footwear with non-slip soles; snug-fitting clothing; beavy-_duty,

non-slip gloves; eye protection such as non-fogging, 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.

OPERATEYOUR 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 o_er parts im-

mediately if hey become damaged, broken, or are ogqerwise 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 _qeremoval of safety devices may cause damage to the unit and possible injury to the operator or by-

standers. Use only Craflsman'" 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 Sercice Center

unless o_qerwise 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 al! 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.

Clear The Working Area

z&_____°_=

_WARNING:Avoidkickbackwhich

canresultin serious injury. 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 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.

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 con_'ibutes to acci- dents.

• Never Iet 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 Iet the guide bar contact another branch or

other objects around it.

• Keep saw chain sharp and propedy 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. Ifthe 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 Pull4n:

• 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

• 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.

• Stand with your weight evenly bal-

anced on both feet.

• Do not overreach. You couId be drawn

or thrown off balance and lose control.

• Do not cut above shoulder height. It is

difficuIt to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

AIL

_IbWARNING: The following features

are included on your saw to help reduce hazard of kickback; however, such fea-

tures wtll 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 serous 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-tlne" 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.

IIWAI_NINIJ: 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 ai- 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 ofthese 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. YOU SHOULD 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 iow 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.

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 Gasotine-Powered Chain Saws Safety Requirements (ANSI

B175.1-2000).

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 first 15 minutes of operation. You should check your chain tension fre-

quently. See CHAIN TENSION under the SERVICE AND ADJUSTMENTS section.

_kWARNING: 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

At=

*_IbWARNING: 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 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 fi. oz.).

Lack ofoiI 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

At=

nWARNING: 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 ounces of oil with

1 gallon of unleaded gasoline. In-

cluded with this saw is a 3.2 ounce

container of Craftsman brand synthetic

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 marine

oil. These oils will cause engine dam-

age. When mixing fuel, follow 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 aicohol

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 fueI system should be

emptied before storage for 30 days or longer. Drain the gas tank, start the en- 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 clean- er products in the fuel tank or perma- nent damage may occur.

See the STORAGE section for addition- al 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 disen- gaged before cutting with the saw.

AIL___________=

all.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.

ing the choke/fast idle lever in com- pletely (to the OFF CHOKE position) and then following the warm engine starting procedure listed above. En-

sure the ON/STOP switch is in the ON position. Starting could require many

pulls depending on how badly the unit is flooded. If engine still fails to start,

refer to the TROUBLESHOOTING TABLE or call 1-800-235-5878.

CHAIN BRAKE *_IbWARNING: 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 possibIe.

• When cutting with the saw, the chain

brake must be disengaged.

Hold the chain saw approximately 14"

(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. Do not cut metal,

plastics, masonry, non-wood 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 a!- 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 the chain, bar and engine. It is recommended that the engine

not be operated for longer than 30 seconds at full throttle.

• 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

I' +- +O +_ - Direction of fall

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. 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 1/3 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.

Felling cut here

First cut _'i

• 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 fail

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, 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 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. *_IbWARNING: 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

SUCKING

_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 Iog. When overcutting use light downward pressure.

• Finish with your second cut.

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.

_I_WARNING: 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 lhe 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 illustration 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 illustration below for your first and second cut).

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

LIMBING AND PRUNING

_IbWARNING: Be alert for and guard against kickback. Do not allow De mov- ing chain to contact any other branches or objects at the nose of the guide bar

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

_I_WARNING: 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 cau-

tion when cutting small size limbs.

• Be alert for springback from any 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.

• 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 one cut.

• Keep the tree between you and the

• Make your first cut 1/3 of the way through the bottom of the limb. This cut will make the limb sag so that it falls easily on the second cut.

• Next make the second cut an over- cut all the way through the limb.

• Finish the pruning operation by using an overcut so that the stump of the

limb protrudes 1 to 2 inches from the trunk of the tree.

• 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

_I_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 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.

2. Loosen chain brake nuts until they are finger tight against the chain

brake.

3. Turn adjusting screw clockwise un- til chain solidly contacts bottom of

guide bar rail.

4. Using bar tool, roll chain around guide bar to ensure all links are in

bar groove.

5. Lift up tip of guide bar to check for sag. Release tip of guide bar, then turn adjusting screw until sag does

not exist.

6. While lifting tip of guide bar, tighten chain brake nuts securely with the

bar tool.

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.

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

jump offthe guide bar and result in se-

rious injury. CHECK CHAIN SHARPNESS A sharp chain makes wood chips. A

dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARP_

ENING in the SERVICE AND ADJUST_ MENTS section.

CHECK GUIDE BAR Conditions which require guide bar

maintenance:

• Saw cuts to one side or at an angle.

• Saw has to be forced through the cut.

• Inadequate supply of oil to bar/chain.

Check the condition of guide bar each time chain is sharpened. A worn guide

bar will damage the chain and make cutting difficult.

After each use, ensure ON/STOP

switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

• Move ON/STOP switch to STOP.

• Loosen and remove chain brake nuts and chain brake. Remove bar

and chain from saw.

• Clean the oil holes and bar groove

after each 5 hours of operation.

Remove Sawdust From

CLEAN AIR FILTER A dirty air filter decreases the life and

performance of the engine and in- creases fuel consumption and harmful

emissions. Always clean your air filter after 15 tanks of fuel or 5 hours of op-

eration, whichever comes first. Clean more frequently in dusty conditions. A

used air filter can never be completely cleaned. It is advisable to replace your

air filter with a new one after every 50 hours of operation, or annually, which-

ever comes first. To clean filter:

1. Loosen 3 screws on cylinder cover.

2. Remove cylinder cover.

3. Remove air filter.

4. Clean the air filter using hot soapy

water. Rinse with clean cool water. Air dry completely before reinstal- ling.

5. Lightly oil air filter before installing

to improve the efficiency of air filter.

Use 2-cycle engine oil or motor oil

(SAE 30). Squeeze excess oil from filter.

6. Reinstall air filter.

7. Reinstall cylinder cover and 3

screws. Tighten securely.
