Always use two hands when operating the chain saw.

WARNING! Contacting the guide bar tip with any object

should be avoided; tip contact may cause the guide bar to move suddenly upward and backward, which may cause se- rious injury.

Measured maximum kickback value without chain brake for the bar and chain combination on the label.

WARNING: Always disconnect

spark plug wire and place wire where it can- not contact spark plug to prevent accidental starting when setting up, transporting, ad- justing or making repairs except carburetor adjustments.

Because a chain saw is a high-speed wood- cutting tool, special safety precautions must be observed to reduce the risk of accidents. Careless or improper use of this tool can cause serious injury.

PLAN AHEAD

SRead this manual carefully until you com- pletely understand and can follow all safety rules, precautions, and operating instruc-

tions before attempting to use the unit.

SRestrict the use of your saw to adult users who understand and can follow safety rules, precautions, and operating instruc-

tions found in this manual.

SWear protective gear. Always use steel-toed safety footwear with non-slip soles; snug-fit- ting 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 plugs or mufflers) to protect your hearing. Regular users should have hearing checked regular- ly as chain saw noise can damage hearing. Secure hair above shoulder length.

SKeep all parts of your body away from the chain when the engine is running.

SKeep children, bystanders, and animals a minimum of 30 feet (10 meters) away from

the work area. Do not allow other people or animals to be near the chain saw when starting or operating the chain saw.

S 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. Chain saw work is strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a chain saw.

SCarefully plan your sawing operation in ad- vance. Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path.

OPERATE YOUR SAW SAFELY

SDo not operate a chain saw with one hand. Serious injury to the operator, helpers, by- standers or any combination of these per- sons may result from one-handed opera- tion. A chain saw is intended for two-handed use.

SOperate the chain saw only in a well-venti- lated outdoor area.

S Do not operate saw from a ladder or in a tree.

SMake 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.

SDo not put pressure on the saw at the end of the cut. Applying pressure can cause you to lose control when the cut is com-

pleted.

S Stop the engine before setting the saw down.

SDo not operate a chain saw that is dam- aged, improperly adjusted, or not com- pletely and securely assembled. Always replace bar, chain, hand guard, or chain brake immediately if it becomes damaged,

broken or is otherwise removed.

S With the engine stopped, hand carry the chain saw with the muffler away from your body, and the guide bar and chain to the rear, preferably covered with a scabbard.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

SHave all chain saw service performed by a qualified service dealer with the exception of the items listed in the maintenance sec- tion of this manual. For example, if improp- er tools are used to remove or hold the fly- wheel when servicing the clutch, structural

damage to the flywheel can occur and cause the flywheel to burst.

SMake certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETOR AD-

JUSTMENTS.

S Never modify your saw in any way.

S Keep the handles dry, clean, and free of oil or fuel mixture.

S Keep fuel and oil caps, screws, and fas- teners securely tightened.

S Use only HusqvarnaR accessories and replacement parts as recommended.

HANDLE FUEL WITH CAUTION

S Do not smoke while handling fuel or while operating the saw.

SEliminate all sources of sparks or flame in the areas where fuel is mixed or poured. There should be no smoking, open flames, or work that could cause sparks. Allow en- gine to cool before refueling.

S Mix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked container for all fuel purposes. Wipe up all fuel spills before starting saw.

SMove at least 10 feet (3 meters) from fuel- ing site before starting engine.

STurn 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.

SStore the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.

KICKBACK

WARNING: 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 con- tacts 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 ob- ject in the wood can also result in loss of chain saw control.

SRotational Kickback can occur when the moving chain contacts an object at the up- per 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 to- ward the operator.

SPinch-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 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.

S 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 stopping pulls the saw forward and away from the operator and could easily cause the operator to lose control of the saw.

Avoid Pinch-Kickback:

S Be extremely aware of situations or ob- structions that can cause material to pinch the top of or otherwise stop the chain.

S Do not cut more than one log at a time. S Do not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull-In:

S Always begin cutting with the engine at full speed and the saw housing against wood.

S Use wedges made of plastic or wood. Never use metal to hold the cut open.

Kickback Path

Avoid Obstructions

Clear The Working Area

REDUCE THE CHANCE OF

KICKBACK

S Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.

S Never let the moving chain contact any ob- ject at the tip of the guide bar.

SKeep the 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 you are cutting. When cutting a

branch, do not let the guide bar contact branch or other objects around it.

SKeep your saw chain sharp and properly tensioned. A loose or dull chain can in- crease the chance of kickback occurring. Follow manufacturer ???s chain sharpening and maintenance instructions. Check ten- sion at regular intervals with the engine

stopped, never with the engine running. Make sure the chain brake nuts are se- curely tightened after tensioning the chain.

SBegin and continue cutting at full speed. If the chain is moving at a slower speed,

there is greater chance of kickback occur- ring.

S Cut one log at a time.

S Use extreme caution when re-entering a previous cut.

SDo not attempt cuts starting with the tip of the bar (plunge cuts).

SWatch for shifting logs or other forces that could close a cut and pinch or fall into

chain.

S Use the Reduced--Kickback Guide Bar and Low--Kickback Chain specified for your saw.

MAINTAIN CONTROL

Stand to the left of the saw

Thumb on underside of handlebar

Never reverse hand positions

Elbow locked

Thumb on underside of handlebar

SKeep a good, firm grip on the saw with both hands when the engine is running and don???t let go. A firm grip will help you reduce kickback and maintain control of the saw. Keep the fingers of your left hand encir- cling and your left thumb under the front handlebar. Keep your right hand com- pletely around the rear handle whether your are right handed or left handed. Keep your left arm straight with the elbow

locked.

SPosition your left hand on the front handle- bar 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.

SStand with your weight evenly balanced on both feet.

SStand slightly to the left side of the saw to keep your body from being in a direct line

with the cutting chain.

SDo not overreach. You could be drawn or thrown off balance and lose control of the

saw.

SDo not cut above shoulder height. It is diffi- cult to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features

are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this danger. As a chain saw user, do not rely only on safety de- vices. You must follow all safety precau- tions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury.

SReduced--Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. A Reduced--Kickback Guide Bar has been demonstrated to significantly re- duce the number and seriousness of kick- backs.

Reduced Kickback Symmetrical Guide Bar

SFront Hand Guard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar.

SPosition of front and rear handlebars, de- signed with distance between handles 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 resistance in controlling the pivot of the saw back toward the operator if kick- back occurs.

WARNING: DO NOT RELY UPON

ANY OF THE DEVICES BUILT INTO YOUR

SAW. YOU SHOULD USE THE SAW PROP-

ERLY AND CAREFULLY TO AVOID KICK- BACK. Reduced--kickback guide bars and low--kickback saw chains reduce the chance and magnitude of kickback and are recom- mended. Your saw has a low kickback chain and bar as original equipment. Repairs on a chain brake should be made by an authorized servicing dealer. Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest authorized master service dealer.

S Tip contact in some cases may cause a light- ning fast reverse REACTION, kicking the guide bar up and back toward the operator.

S Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator.

SEither of these reactions may cause you to lose control of the saw which could result in serious injury.Do not rely exclusively upon the safety devices built into your saw.

CHAIN BRAKE

SChain Brake, designed to stop the chain in the event of kickback.

WARNING: Your chain saw is

equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.

DO NOT ASSUME THAT THE CHAIN

BRAKE WILL PROTECT YOU IN THE

EVENT OF A KICKBACK.

SAFETY NOTICE: Exposure to vibrations

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 swellings. 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 monitor closely their physical condition and the condition of this tool.

Protective gloves (not provided) should be worn during assembly.

ATTACHING THE OPTIONAL

BUMPER SPIKE

The optional bumper spike may be used as a pivot when making a cut.

S Loosen and remove the chain brake nuts and the chain brake from the saw.

SAttach the bumper spike (optional) with the two screws as illustrated.

ATTACHING THE BAR & CHAIN (If not

already attached)

WARNING: If received assembled,

repeat all steps to ensure your saw is prop- erly assembled and all fasteners are secure. Always wear gloves when handling the chain. The chain is sharp and can cut you even when it is not moving!

SLoosen and remove the chain brake nuts and the chain brake from the saw.

S Remove the plastic shipping spacer (if present).

Location of shipping spacer

SAn adjusting pin and screw is used to adjust the tension of the chain. It is very important when assembling the bar, that the pin located on the adjusting screw aligns into a hole in the bar. Turning the screw will move the ad- justment pin up and down the screw. Locate this adjustment before you begin mounting the bar onto the saw. See illustration below.

Inside view of

Chain Brake

Adjustment located on Chain Brake

STurn the adjusting screw by hand counter- clockwise until the adjusting pin just touches the stop. This should allow the pin to be near the correct position. Further adjustment may be necessary as you mount the bar.

S Slide guide bar behind clutch drum until guide bar stops against clutch drum sprocket.

Mount the bar

SPrepare the chain by checking the proper di- rection. Without following the illustration it is easy to place the chain on the saw in the wrong direction. Use the illustration of the chain to determine the proper direction.

Drive Links

S Place the chain over and behind the clutch, fitting the drive links in the clutch drum sprocket.

SFit bottom of drive links between the teeth in the sprocket in the nose of the guide bar.

S Fit chain drive links in bar groove.

S Pull the bar forward until the chain is snug in the guide bar groove. Ensure all drive links are in the bar groove.

SNow, install chain brake making sure the adjusting pin is positioned in the lower hole

in the guide bar. Remember this pin moves the bar forward and backward as the screw is turned.

SInstall chain brake nuts and finger tighten only. Once the chain is tensioned, you will need to tighten chain brake nuts.

CHAIN TENSION (Including units with chain already installed)

NOTE: When adjusting chain tension, make sure the chain brake nuts are finger tight only. Attempting to tension the chain when the chain brake nuts are tight can cause damage.

Checking the tension:

Use the screwdriver end of the chain adjust- ment tool (bar tool) to move the chain around the bar. If the chain does not rotate, it is too tight. If too loose, the chain will sag below the bar.

Adjusting the tension:

Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

You can adjust the chain tension by loosening the chain brake nuts and turning the adjusting screw 1/4 of a turn while lifting up on the bar.

SIf chain is too tight, turn adjusting screw 1/4 turn counterclockwise.

SIf chain is too loose, turn adjusting screw 1/4 turn clockwise.

WARNING: If the saw is operated

with a loose chain, the chain could jump off the guide bar and result in serious injury.

WARNING: Muffler is very hot dur- ing and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so.

WARNING: Remove fuel cap slow- ly when refueling.

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 HusqvarnaR brand oil. If you do not use this oil, use a good quality 2-cycle air-cooled oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 0,125 liter of oil with 5 liters of unleaded gasoline. DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules listed under HANDLE

FUEL WITH CAUTION.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.

Only use Bar and Chain Oil for bar and chain lubrication.

WARNING: The chain must not

move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR- BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.

To stop the engine move the ON/STOP switch to the STOP 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.

Use only 15???---18??? of rope per pull. Hold saw firmly while pulling starter rope

Starter rope handle

Left hand on front handle

Right foot through rear handle

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly.

For cold weather starting, start the unit at FULL CHOKE; allow the engine to warm up before squeezing the throttle trigger.

NOTE: Do not cut material with the choke/ fast idle lever at the FULL CHOKE position.

STARTING A COLD ENGINE (or warm engine after running out of fuel):

NOTE: In the following steps, when the choke/fast idle lever is pulled out to the full extent, the correct throttle setting for starting is set automatically.

S Move ON/STOP switch to the ON position.

SPull the choke/fast idle lever out to the full extent.

S Pull starter rope quickly with your right hand a maximum of 10 times.

NOTE: If the engine sounds as if it is trying

to start before the 10th pull, stop pulling and immediately proceed to the next step.

SPush the choke/fast idle lever in complete- ly (to the OFF CHOKE position).

SPull the starter rope quickly with your right hand until the engine starts.

SAllow the engine to run for approximately 5 seconds. Then, squeeze and release throttle trigger to allow engine to return to idle speed.

STARTING A WARM ENGINE

S Move ON/STOP switch to the ON position.

SPull the choke/fast idle lever out to the full ex- tent; then, push the lever back in completely (to the OFF CHOKE position). This will set

the fast idle lock to the start position.

SPull the starter rope quickly with your right hand until the engine starts.

SSqueeze and release the throttle trigger to allow engine to return to idle speed.

DIFFICULT STARTING (or starting a flooded engine)

The engine may be flooded if it has not started after 10 pulls.

Flooded engines can be cleared of excess fuel by following the warm engine starting proce- dure listed above. Ensure the ON/STOP switch is in the ON position.

Starting could require many pulls depending on how badly unit is flooded. If engine still fails to start, refer to the TROUBLESHOOTING

TABLE.

CHAIN BRAKE

WARNING: If the 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 should be replaced by an autho- rized service dealer if any part is worn to less than 1/32??? thick. Repairs on a chain brake should be made by an authorized service dealer. Take your unit to the place of pur- chase if purchased from a servicing dealer, or to the nearest authorized master service dealer.

S This saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.

S The inertia--activated chain brake is activated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement).

S If the brake is already activated, it is disengaged by pulling the front hand guard back toward the front handle as far as possible.

SWhen cutting with the saw, the chain brake must be disengaged.

Disengaged

Engaged

Braking function control

CAUTION: The chain brake must be checked several times daily. The engine must be running when performing this proce- dure. This is the only instance when the saw should be placed on the ground with the en- gine running.

Place the saw on firm ground. Grip the rear handle with your right hand and the front han- dle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain should stop immediately.

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??? (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.

IMPORTANT POINTS

S Check chain tension before first use and af- ter 1 minute of operation. See CHAIN TEN- SION in the ASSEMBLY section.

S Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc.

SStop the saw if the chain strikes a foreign ob- ject. Inspect the saw and repair or replace parts as necessary.

SKeep the chain out of dirt and sand. Even a small amount of dirt will quickly dull a chain and thus increase the possibility of kickback.

SPractice cutting a few small logs using the following techniques to get the ???feel??? of using

your saw before you begin a major sawing operation.

SSqueeze the throttle trigger and allow the engine to reach full speed before cutting.

S Begin cutting with the saw frame against the log.

SKeep the engine at full speed the entire time you are cutting.

SAllow the chain to cut for you. Exert only light downward pressure. If you force the

cut, damage to the bar, chain, or engine can result.

SRelease the throttle trigger as soon as the cut is completed, allowing the engine to idle. If you run the saw at full throttle with- out a cutting load, unnecessary wear can

occur to the chain, bar, and engine.

STo avoid losing control when cut is com- plete, do not put pressure on saw at end

of cut.

SStop the engine before setting the saw down after cutting.

TREE FELLING TECHNIQUES

WARNING: Check for broken or dead branches which can fall while cutting causing serious injury. Do not cut near build- ings or electrical wires if you do not know the direction of tree fall, nor cut at night since you will not be ale to see well, nor during bad weather such as rain, snow, or strong winds, etc. If the tree makes contact with any utility line, the utility company should be notified im- mediately.

SCarefully plan your sawing operation in ad- vance.

S Clear the work area. You need a clear area all around the tree so you can have secure footing.

S 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.

SStudy the natural conditions that can cause the tree to fall in a particular direction.

Natural conditions that can cause a tree to fall in a particular direction include:

S The wind direction and speed.

S 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 de- termine the direction of tree lean.

S Weight and branches on one side. S Surrounding trees and obstacles.

Look for decay and rot. If the 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 distance of 2-1/2 tree lengths from the nearest person or other objects. En- gine noise can drown out a warning call.

Remove dirt, stones, loose bark, nails, sta- ples, and wire from the tree where cuts are to be made.

Plan a clear retreat path to the rear and diag- onal to the line 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 de- sired 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 us- ing saw to remove buttress roots, keep saw chain from contacting ground to prevent dull- ing of the chain.

NOTCH CUT AND FELLING THE

TREE

S 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 cut- ting the bottom of the notch. See illustra- tion. Once the notch is cut, remove the notch of wood from the tree.

Final cut here. 2 inches above First cut center of notch.

Notch

Second cut

S After removing the wood from the notch, make the felling cut on the opposite 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

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.

S Be alert to signs that the tree is ready to fall: cracking sounds, widening of the felling cut, or movement in the upper branches.

SAs tree starts to fall, stop saw, put it down, and get away quickly on your planned re- treat path.

S 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 com- pletely, 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.

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

S Cut only one log at a time.

S Cut shattered wood very carefully; sharp pieces of wood could be flung toward opera- tor.

SUse 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.

S 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

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.

Overcutting begins on the top side of the log with the bottom of the saw against the log. When overcutting use light downward pres- sure.

Overcutting Undercutting

Undercutting involves cutting on the under- side of the log with top of saw against the log. When undercutting use light upward pres- sure. 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 con- trolled in this position.

Always make your first cut on the compres- sion side of the log. The compression side of the log is where the pressure of the log???s weight is concentrated.

First cut on compression side of log

Second cut

Second cut

First cut on compression side of log

BUCKING WITHOUT A SUPPORT

SOvercut through 1/3 of the diameter of the log.

SRoll the log over and finish with a second overcut.

SWatch for logs with a compression side to prevent the saw from pinching. See il- lustrations for cutting logs with a compres- sion side.

BUCKING USING A LOG OR

SUPPORT STAND

S Remember your first cut is always on the compression side of the log. (Refer to the il- lustrations below for your first and second cut)

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

S 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 ob- jects at the nose of the guide bar when limb- ing or pruning. Allowing such contact can re- sult in serious injury.

WARNING: Never climb into a tree

to limb or prune. Do not stand on ladders, platforms, a log, or in any position which can cause you to lose your balance or control of the saw.

IMPORTANT POINTS

S Work slowly, keeping both hands firmly gripped on the saw. Maintain secure foot- ing and balance.

S Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material may catch the saw chain and be whipped toward you or pull you off balance.

S 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.

SKeep a clear work area. Frequently clear branches out of the way to avoid tripping over them.

LIMBING

SAlways limb a tree after it is cut down. Only then can limbing be done safely and prop-

erly.

S Leave the larger limbs underneath the felled tree to support the tree as you work.

SStart at the base of the felled tree and work toward the top, cutting branches and

limbs. Remove small limbs with one cut.

SKeep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting.

S Remove larger, supporting branches with the cutting techniques described in BUCK-

ING WITHOUT A SUPPORT.

S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch the saw.

PRUNING

WARNING: Limit pruning to limbs

shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job.

SMake your fist cut 1/3 of the way through the bottom of the limb.

SNext make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch collar from the truck of the tree.

AIR FILTER

CAUTION: Do not clean filter in gasoline

or other flammable solvent to avoid creating a fire hazard or producing harmful evapora- tive emissions.

Cleaning the air filter:

A dirty air filter decreases engine perform- ance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation.

SClean the cover and the area around it to keep dirt and sawdust from falling into the

carburetor chamber when the cover is re- moved.

S Remove the parts as illustrated below.

S Wash the filter in soap and water. Rinse in clean cool water. Air dry completely before reinstalling.

S Reinstall parts.

CARBURETOR ADJUSTMENTS

Your carburetor is equipped with limiter caps. Carburetor adjustment is a compli- cated task. We recommend that you take your unit to an authorized service dealer. Damage will occur if you turn the needles be- yond the limiter stops.

BAR MAINTENANCE

If your saw cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be neces- sary to service your bar. A worn bar will dam- age your chain and make cutting difficult.

Replace your bar if bent or the inside rails of the bar are worn.

S Clean the oil holes after each 5 hours of op- eration.

SRemove sawdust from bar groove periodi- cally with a wire or putty knife.
