A.A Summary of Warnings on kickback and other Selected Risks – Taken Primarily from ANSI B 175.1 (See also “Safety Precautions“ section of this Owner’s Manual)

!Warning!Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator.Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury.

Section 5.11 of ANSI B 175.1-2000 sets certain performance and design criteria related to chainsaw kickback. STIHL has developed a color code system using green and yellow to help you select a powerhead, bar and chain combination that complies with the kickback requirements of the ANSI Standard. See the sections entitled "Safety Precautions" and "Specifications" of this manual.

Do not rely exclusively upon the safety devices built into your saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.

1. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

2. Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chainsaw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don't let go.

3. Make sure the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction that could be hit while you are operating the saw.

4. Cut at high engine speeds.5. Do not overreach or cut above

shoulder height.

6. Follow manufacturer's sharpening and maintenance instructions for the saw chain.

7. Only use replacement bars and chains specified by the manufacturer or the equivalent.

8. Reduced kickback bars and low kickback chains are designed to reduce the risk of kickback injury. Ask your STIHL dealer about these devices.

B.Other Safety Precautions

!Warning!1. Do not operate a chainsaw with one

hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chainsaw is intended to be used with two hands.

2. Do not operate a chainsaw when you are fatigued.

3. Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing, and head protection devices.

The use of any chainsawmay be hazardous.The saw chain has manysharp cutters. If thecutters contact your flesh,

they will cut you, even if the chain is notmoving. At full throttle, the chain speedcan reach 45 mph (20 m/s). It is impor-tant that you read, fully understandand observe the following safety precau-tions and warnings. Read the Owner’sManual �� the safety instructionsperiodically.

Pay special attention to the section onreactive forces.

��Reactive forces, including kickback, canbe dangerous. Careless or improper useof any chainsaw may cause serious orfatal injury.

All safety precautions that are generallyobserved when working with an ax or ahand saw also apply to the operation ofchainsaws. However, because a chain-saw is a high-speed, fast-cutting powertool, special safety precautions must beobserved to reduce the risk of personalinjury.

Have your STIHL dealer show you howto operate your chainsaw. Observe allapplicable local safety regulations,standards and ordinances.

��Minors should never be allowed to use achainsaw. Bystanders, especiallychildren, and animals should not beallowed in the area where a chainsaw isin use. Never let the saw run unattended.Store it in a locked place away fromchildren and empty the fuel tank beforestoring for longer than a few days.

Do not lend or rent yourchainsaw without theOwner‘s Manual. Be surethat anyone using yoursaw reads and under-

stands the information contained in thismanual.

These safety precautions and warningsapply to the use of all STIHL chainsaws.Different models may have differentparts and controls. See the appropriatesection of your Owner’s Manual for adescription of the controls and functionof the parts of your model saw.

Safe use of a chainsaw involves

1. the operator2. the saw3. the use of the saw.

��

��

You must be in good physical conditionand mental health and not under theinfluence of any substance (drugs,alcohol) which might impair vision,dexterity or judgment.

Do not operate a chainsaw when you arefatigued. Be alert – If you get tired whileoperating your chainsaw, take a break.Tiredness may result in loss of control.Working with any chainsaw can bestrenuous. If you have any condition thatmight be aggravated by strenuous work,check with your doctor before operatinga chainsaw.

��Prolonged use of chainsaws (or othermachines) exposing the operator tovibrations may produce whitefingerdisease (Raynaud’s phenomenon) orcarpal tunnel syndrome. These conditions

��

�

reduce the hand’s ability to feel andregulate temperature, produce numb-ness and burning sensations and maycause nerve and circulation damage andtissue necrosis.

All factors which contribute to whitefingerdisease are not known, but cold weather,smoking and diseases or physical condi-tions that affect blood vessels and bloodtransport, as well as high vibration levelsand long periods of exposure to vibrationare mentioned as factors in the develop-ment of whitefinger disease. In order toreduce the risk of whitefinger diseaseand carpal tunnel syndrome, pleasenote the following:

The STIHL 009 is not equipped with anantivibration (AV) system.

– Many STIHL models are availablewith an anti-vibration (“AV”) systemdesigned to reduce the transmissionof vibrations created by the engineand cutting attachment to theoperator’s hands. An AV system isrecommended for those personsusing chainsaws on a regular orsustained basis.

– Wear gloves and keep your handswarm. Heated handles, which areavailable on most STIHL power-heads, are recommended for coldweather use.

– Keep the saw chain sharp and the saw, including the AV system, wellmaintained. A dull chain will in-crease cutting time, and pressing adull chain through wood will in-crease the vibrations transmitted toyour hands. A saw with loose com-ponents or with damaged or wornAV buffers will also tend to havehigher vibration levels.

– Maintain a firm grip at all times, butdo not squeeze the handles withconstant, excessive pressures.Take frequent breaks.

All the above mentioned precautions donot guarantee that you will not sustainwhitefinger disease or carpal tunnelsyndrome. Therefore, continual andregular users should monitor closely thecondition of their hands and fingers.If any of the above symptoms appear,seek medical advice immediately.

��

��To reduce the risk of injury, the operatorshould wear proper protective apparel.

Clothing must be sturdyand snug-fitting, but allowcomplete freedom ofmovement. Avoid loose-fitting jackets, scarfs,

neckties, jewelry, flared or cuffed pants,unconfined long hair or anything thatcould become entangled with the saw orbrush. Wear overalls or jeans with areinforced cut retardant insert or cutretardant chaps.

Protect your hands with gloves when handling sawand saw chain.Heavyduty, nonslipgloves improve your gripand protect your hands.

Good footing is mostimportant in chainsawwork. Wear sturdy bootswith nonslip soles.Steel-toed safety boots are recommended.

To reduce the risk of injury to your eyesnever operate a chainsaw unlesswearing goggles or properly fitted safetyglasses with adequate top and sideprotection complying with your nationalstandard.

�

Wear an approved safetyhard hat to protect yourhead. Chainsaw noise maydamage your hearing. Always wear sound

barriers (ear plugs or ear mufflers) to protect your hearing. Continual and regular users should have their hearingchecked regularly.

��

Parts of the chainsaw; for illustrationsand definitions of the parts see thechapter on “Main Parts of Saw”.

��Never modify a chainsaw in any way.Only attachments and parts supplied bySTIHL or expressly approved by STIHLfor use with the specific STIHL sawmodels are authorized. Although certainunauthorized attachments are useablewith the STIHL powerhead, their usemay, in fact, be extremely dangerous.

�� !��

��"

��Always stop the engine before putting achainsaw down or carrying it. Carrying achainsaw with the engine running isextremely dangerous.

Accidental acceleration of the enginecan cause the chain to rotate. Duringoperation, the powerhead muffler andthe material around it reach extremelyhigh temperatures. Avoid touching thehot muffler, you could receive seriousburns.

#��$�When carrying your saw byhand, the engine must be stopped andthe saw must be in the proper position.

Grip the front handle and place themuffler away from the body.

The chain guard (scabbard) should beover the chain and the guide bar, whichshould point backwards. When carryingyour saw, the bar should be behind you.

#��%��$�When transporting in avehicle, keep chain and bar covered withthe chain guard. Properly secure yoursaw to prevent turnover, fuel spillageand damage to the saw.

��"

Take off the chain guard and inspect forsafety in operation. For assembly, followthe procedure described in the chapter“Mounting the Bar and Chain” of yourOwner’s Manual.

STIHL Oilomatic chain, guide bar andsprocket must match each other ingauge and pitch.

Before replacing any bar and chain,see the sections on “Specifications”,"Kickback" and the "ANSI B 175.1-2000chainsaw kickback standard" in this manual.

��Proper tension of the chain is extremelyimportant. In order to avoid impropersetting, the tensioning procedure mustbe followed as described in your manual.Always make sure the hexagonal nut(s)for the sprocket cover is (are) tightenedsecurely after tensioning the chain.Never start the saw with the sprocketcover loose. Check chain tension oncemore after having tightened the nut(s)and thereafter at regular intervals (when-ever the saw is shut off). If the chainbecomes loose while cutting, shut off theengine and then tighten. Never try totighten the chain while the engine isrunning!

!��

Your STIHL chainsaw uses an oil-gaso-line mixture for fuel (see chapter “Fuel”of your Owner’s Manual).

��Gasoline is an extremely flammable fuel.If spilled or ignited by a spark or otherignition source, it can cause fire andserious burn injury or property damage.Use extreme caution when handlinggasoline or fuel mix.

Do not smoke or bring anyfire or flame near the fuelor the chainsaw. Note thatcombustible fuel vaporsmay be vented from thefuel system.

!��'��

��Fuel your chainsaw in well-ventilatedareas, outdoors only. Always shut off theengine and allow it to cool before refue-ling. Gasoline vapor pressure may buildup inside the gas tank of a two cycleengine depending on the fuel used, theweather conditions, and the venting system of the tank. In order to reduce

the risk of burns or other personal injuryfrom escaping gas vapor and fumes,remove the fuel filler cap on the STIHLproduct carefully so as to allow anypressure build-up in the tank to releaseslowly. Never remove fuel filler cap whileengine is running.

Select bare ground for fueling and moveat least 10 feet (3 m) from fueling spotbefore starting the engine. Wipe off anyspilled fuel before starting your saw, andcheck for leakage.

��Check for fuel leakage while refuelingand during operation. If fuel or oil leakageis found, do not start or run the engineuntil leak is fixed and spilled fuel hasbeen wiped away. Take care not to getfuel on your clothing. If this happens,change your clothing immediately.

Different models may have different fuelcaps.

��"��(��

��In order to reduce the risk of fuel spillageand fire from an improperly tightenedfuel cap, correctly position and tightenthe fuel cap in the fuel tank opening.

)

To do this with this STIHLcap, raise the grip on thetop of the cap until it is up-right at a 90° angle. Insert

the cap and the fuel tank opening withthe triangular marks on the grip of thecap and on the fuel tank opening liningup. Using the grip, turn the cap firmlyclockwise as far as it will go (approx. aquarter turn).

Fold the grip flush with thetop of the cap. If the gripdoes not lie completelyflush with the cap and the

detent on the grip does not fit in the cor-responding recess in the filler neck, thecap is not properly seated and tightenedand you must repeat the above steps.

��

��Unit vibrations can cause an improperlytightened fuel filler cap to loosen or comeoff and spill quantities of fuel. In order toreduce the risk of fuel spillage and fire,tighten fuel filler cap by hand with asmuch force as possible.

The screwdriver end of theSTIHL combination wrenchor other similar tool can beused as an aid in tighteningslotted fuel filler caps.

See "Fueling" chapter in your Owner’sManual.

��The chain brake must be engaged whenstarting the saw.

��Your chainsaw is a one-person saw.Do not allow other persons to be nearthe running chainsaw. Start and operateyour saw without assistance. For speci-fic starting instructions, see the appro-priate section of the Owner’s Manual.Proper starting methods reduce the riskof injury. Do not drop start. This methodis very dangerous because you maylose control of the saw.

There are two recommended methodsfor starting your chainsaw.

With the ��*��+�the chainsaw isstarted on the ground. Make sure thechain brake is engaged (see “ChainBrake” chapter in your Owner’s Manual)and place the chainsaw on firm groundor other solid surface in an open area.Maintain good balance and securefooting.

Grip the front handlebar of the saw firmlywith your left hand and press down.For saws with a rear handle level withthe ground, put the toe of your right footinto the rear handle and press down.With your right hand pull out the startergrip slowly until you feel a definiteresistance and then give it a brisk,strong pull.

The ��recommended *��forstarting your chainsaw allows you to startthe saw without placing it on theground. Make sure the chain brake isengaged, grip the front handle of thechainsaw firmly with your left hand.Keep your arm on the front handle in alocked (straight) position. Hold the rearhandle of the saw tightly between yourlegs just above the knees. Maintain goodbalance and secure footing. Pull thestarting grip slowly with your right handuntil you feel a definite resistance and thengive it a brisk, strong pull.

��Be sure that the guide bar and chain areclear of you and all other obstructionsand objects, including the ground. Whenthe engine is started, the engine speedwith the starting throttle lock engagedwill be fast enough for the clutch toengage the sprocket and, if the chainbrake is not activated, turn the chain. If the upper quadrant of the tip of the bartouches any object, it may cause kick-back to occur (see section on reactiveforces). To reduce this risk, always engage the chain brake before starting.Never attempt to start the chainsawwhen the guide bar is in a cut or kerf.

��When you pull the starter grip, do notwrap the starting rope around yourhands. Do not allow the grip to snapback, but guide the starter rope slowlyback to permit the rope to rewindproperly. Failure to follow this proceduremay result in injury to hand or fingersand may damage the starter mechanism.

'*��-��*��

��To reduce the risk of personal injury fromloss of control or contact with therunning chain, do not use a saw withincorrect idle adjustment. At correct idlespeed, the chain should not rotate. Fordirections to adjust idle speed, see theappropriate section of your Owner’sManual. If you cannot set the correct idlespeed, have your STIHL dealer checkyour saw and make proper adjustmentsor repairs.

After adjusting a chain, start the saw, letthe engine run for a while, then switchengine off and recheck chain tension.Proper chain tension is very important atall times.

��.��

Operate the chainsaw under goodvisibility and daylight conditions only.

��Your chainsaw producespoisonous exhaust fumesas soon as the combustibleengine is running.These gases (e.g. carbon

monoxide) may be colorless and odor-less.

To reduce the risk of serious or fatalinjury from breathing toxic fumes, neverrun the chainsaw indoors or in poorlyventilated locations. Ensure proper venti-lation when working in trenches or otherconfined areas.

��Use of this product (including sharpen-ing the saw chain) can generate dust,mists and fumes containing chemicalsknown to cause respiratory disease, can-cer, birth defects, or other reproductiveharm. If you are unfamiliar with the risksassociated with the particular dust, mistor fume at issue, consult your employer,governmental agencies such as OSHAand NIOSH and other sources on hazardous materials. California andsome other authorities, for instance,have published lists of substancesknown to cause cancer, reproductive toxicity, etc.

Control dust (such as sawdust), mists(such as oil mist from chain lubrication)and fumes at the source where possible.In this regard use good work practicesand follow the recommendations ofOSHA / NIOSH and occupational andtrade associations. When the inhalationof toxic dust, mists and fumes cannot be

/

eliminated, the operator and any by-standers should always wear a respiratorapproved by NIOSH / MSHA for the typesubstance at issue.

��Breathing asbestos dust is dangerousand can cause severe or fatal injury, re-spiratory illness or cancer. The use anddisposal of asbestos containing productshave been strictly regulated by OSHAand the Environmental Protection Agen-cy. Do not cut or disturb asbestos, asbe-stos containing products (e.g. asbestoscontaining drywall or other constructionproducts), or products such as pipeswhich are wrapped or covered with asbe-stos insulation. If you have any reasonto believe that you might be cutting asbe-stos, immediately contact your employeror a local OSHA representative.

The muffler and other parts of the engine(e.g. fins of the cylinder, spark plug)become hot during operation and remainhot for a while after stopping the engine.To reduce risk of burns do not touch themuffler and other parts while they are

hot. Don’t work alone. Keep within callingdistance of others in case help is needed.

Your chainsaw is equipped with a chaincatcher. It is designed to reduce the riskof personal injury in the event of a thrownor broken chain. From time to time thecatcher may be damaged or removed.To reduce the risk of personal injury,do not operate a chainsaw with adamaged or missing catcher.

Inspect buffers periodically. Replacedamaged, broken or excessively wornbuffers immediately, since they mayresult in loss of control of the saw.

A “sponginess” in the feel of the saw,increased vibration or increased“bottoming” during normal operationmay indicate damage, breakage orexcessive wear. Buffers should alwaysbe replaced in sets. If you have anyquestions as to whether the buffersshould be replaced, consult your STIHLservicing dealer.

��Take extreme care in wet and freezingweather (rain, snow, ice). Put off thework when the weather is windy, stormyor rainfall is heavy.

��Avoid stumbling on obstacles such asstumps, roots or rocks and watch out forholes or ditches. Clear the area whereyou are working. Be extremely cautiouswhen working on slopes or unevenground. There is increased danger ofslipping on freshly debarked logs.

��To reduce the riskof serious or fatal injury to the opera-tor or bystanders, never use the sawwith one hand.

You cannot control reactive forces andyou may lose control of the saw, whichcan result in the skating or bouncing ofthe bar and chain along the limb or log.

Even for those compact saws designedfor use in confined spaces, one-handedoperation is dangerous because theoperator may lose control.

01

��'��Grip: Always hold the saw firmly withboth hands when the engine is running.Place your left hand on front handle barand your right hand on rear handle andthrottle trigger. Left-handers shouldfollow these instructions too.

Wrap your fingers tightly around thehandles, keeping the handles cradledbetween your thumb and forefinger.With your hands in this position, you canbest oppose and absorb the push, pulland kickback forces of your saw withoutlosing control (see section on reactiveforces). Make sure your chainsawhandles and grip are in good conditionand free of moisture, pitch, oil or grease.

��Do not operate your chainsaw with thestarting throttle lock engaged. Cuttingwith the starting throttle lock engageddoes not permit the operator propercontrol of the saw or chain speed.

��Never touch a chain with your hand orany part of your body when the engine isrunning, even when the chain is notrotating. The chain continues to rotatefor a short period after the throttle triggeris released.

��Do not cut any material other than woodor wooden objects.Use your chainsaw for cutting only.It is not designed for prying or shovelingaway limbs, roots or other objects.When sawing, make sure that the sawchain does not touch any foreignmaterials such as rocks, fences, nailsand the like.

Such objects may be flung off, damagethe saw chain or cause the saw tokickback.

��In order to keep control of your saw,always maintain a firm foothold.

Never work on a ladder, or on any otherinsecure support. Never use the sawabove shoulder height.

��Never work in a tree unless you havereceived specific, professional trainingfor such work, are properly secured(such as tackle and harness system or alift bucket), have both hands free foroperating the chainsaw in a crampedenvironment and have taken properprecautions to avoid injury from fallinglimbs or branches.

Position the chainsaw in such a way thatyour body is clear of the cutting attach-ment whenever the engine is running.Stand to the left of cut while bucking.

Don’t put pressure on the saw whenreaching the end of a cut. The pressuremay cause the bar and rotating chain topop out of the cut or kerf, go out ofcontrol and strike the operator or someother object. If the rotating chain strikessome other object, a reactive force maycause the moving chain to strike theoperator.

��%��.��.2��.

��Reactive forces may occur any time thechain is rotating. Reactive forces can bedangerous! In any chainsaw, the

powerful force used to cut wood can bereversed (and work against the opera-tor). If the rotating chain is suddenlystopped by contact with any solid objectlike a log or branch or is pinched, thereactive forces may occur instantly.These reactive forces may result in lossof control which may, in turn, causeserious or fatal injury. An understandingof the causes of these reactive forcesmay helpyou avoid loss of control.

The most common reactive forces are– kickback,– pushback,– pull-in.

3��.2��.$Kickback may occur whenthe moving saw chain nearthe upper quadrant of thebar nose contacts a solidobject or is pinched.

The reaction of the cutting force of thechain causes a rotational force on thechainsaw in the direction opposite to thechain movement. This may fling the barup and back in an uncontrolled arcmainly in the plane of the bar. Undersome cutting circumstances the barmoves towards the operator, who maysuffer severe or fatal injury.

Kickback may occur when the nose ofthe guide bar is pinched unexpectedly,unintentionally contacts solid material inthe wood or is incorrectly used to begina plunge or boring cut.

It may also occur during limbing.The greater the force of the kickbackreaction, the more difficult it becomes forthe operator to control the saw. Manyfactors influence the occurrence andforce of the kickback reaction. Theseinclude chain speed, the speed at whichthe bar and chain contact the object, theangle of contact, the condition of thechain and other factors.

The type of bar and saw chain you useis an important factor in the occurrenceand force of the kickback reaction.Some STIHL bar and chain types aredesigned to reduce kickback forces.STIHL recommends the use of reducedkickback bars and low kickback chains.

Section 5.11 of ANSI standard B 175.1–2000, sets certain performance anddesign criteria related to chainsawkickback.To comply with section 5.11 of ANSI B175.1-2000:

a) saws with a displacement of less than3.8 cubic inches

b) saws with a displacement of 3.8 cubicinches and above

– must be equipped with at least onedevice designed to reduce the riskof kickback injury such as a chainbrake, low kickback chain, reducedkickback bar, etc.

The computer derived angles for sawsbelow 3.8 cubic inch displacement aremeasured by applying a computerprogram to test results from a kickbacktest machine.

��The computer derived angles of § 5.11 ofANSI B 175.1-2000 may bear no rela-tionship to actual kickback bar rotation

angles that may occur in real life cuttingsituations.

Compliance with § 5.11 ofANSI B 175.1-2000 does not automatic-ally mean that in a real life kickback thebar and chain will rotate at most 45°.

��

In order for powerheads below 3.8 cubic

inch displacement to comply with thecomputed kickback angle requirementsof § 5.11 of ANSI B 175.1-2000 use onlythe following cutting attachments:

– bar and chain combinations listed ascomplying in the “Specifications”section of the Owner’s Manual or

– other replacement bar and chaincombinations marked in accordancewith the standard for use on thepowerhead or

– replacement chain designated“low kickback saw chain’’.

STIHL recommends the use of the STIHLQuickstop chain brake on your power-head with green labeled reduced kick-back bars and low kickback chains.

��To reduce the risk of injury, stop usingthe saw immediately if the chain brakedoes not function properly. Take the sawto your local STIHL Service Centre! Donot use the saw until the problem hasbeen rectified (see the section “ChainBrake”).

:��.��2��.�

STIHL has developed a chain stoppingsystem designed to reduce the risk ofinjury in certain kickback situations.It is called a Quickstop chain brake.The Quickstop is available as standardequipment on your STIHL chainsaw andis available for installation on most olderSTIHL saws. Ask your dealer to retrofityour older model saw with a chain brake.

When a kickback occurs, the guide barmay rotate around the front handle. If thecutting position is such that the operator’sleft hand is gripping the front handlebehind the hand guard, and if the lefthand rotates around the front handle andmakes a sufficiently forceful contact withthe front hand guard, which is the Quick-stop activating lever, this contact willactivate the Quickstop. The chain brakeon most new model STIHL chainsawscan also be activated by inertia. See thechapter entitled “Chain Brake” of yourOwner’s Manual.

��Never operate your chainsaw without afront hand guard. In a kickback situationthis guard helps protect your left hand orother parts of your body. In addition,removal of the hand guard on a sawequipped with a chain brake will deactivatethe chain brake.

��No Quickstop or other chain brakedevice prevents kickback. These devicesare designed to reduce the risk ofkickback injury, if activated, in certainkickback situations. In order for theQuickstop to reduce the risk of kickbackinjury, it must be properly maintainedand in good working order. See thechapter entitled “Chain Brake” and“Maintenance, Repair and Storing” ofyour Owner’s Manual. In addition, theremust be enough distance between thebar and the operator to ensure that theQuickstop has sufficient time to activateand stop the chain before potentialcontact with the operator.

��An improperly maintained chain brakemay increase the time needed to stopthe chain after activation, or may notactivate at all.

��Never run the chainsaw above idlespeed for more than 3 seconds whenthe chain brake is engaged or the chainis pinched or otherwise caught in the cut.Clutch slippage can cause excessiveheat, leading to severe damage of themotor housing, clutch and oiler compo-nent and may interfere with the operationof the chain brake. If clutch slippage inexcess of 3 seconds has occured, allowthe motor housing to cool before pro-ceeding and check the operation of yourchain brake as described in the chapterentitled “Chain Brake”. Also make surethat the chain is not turning at idle speed(see above “Important Adjustments”).

STIHL offers a variety of bars andchains. STIHL reduced kickback barsand low kickback chains are designed to

reduce the risk of kickback injury. Otherchains are designed to obtain higher cut-ting efficiency or sharpening ease butmay result in higher kickback tendency.

STIHL has developed a color codesystem to help you identify the STIHLreduced kickback bars and low kick-back chains. Cutting attachments withgreen warning decals or green labels onthe packaging are designed to reducethe risk of kickback injury. The matchingof green decaled powerheads under 3.8cubic inch displacement with greenlabeled bars and green labeled chainsgives compliance with the computedkickback angle requirements of ANSI B175.1-1991 when the products are intheir original condition. Products withyellow decals or labels are for users withextraordinary cutting needs and experience and specialized training fordealing with kickback.

Please ask your STlHL dealer to properlymatch your powerhead with the appro-priate bar/chain combinations to reducethe risk of kickback injury. Green labeledbars and chains are recommended for allpowerheads. See your “STIHL Bar andChain Information” leaflet for details.

��Use of other, non-listed bar/chain combi-nations may increase kickback forcesand increase the risk of kickback injury.New bar/chain combinations may bedeveloped after publication of this litera-ture, which will, in combination withcertain powerheads, comply with § 5.11of ANSI B 175.1-2000. Check with yourSTIHL dealer for such combinations.

��Reduced kickback bars and low kickbackchains do not prevent kickback, but theyare designed to reduce the risk of kick-back injury. They are available from yourSTIHL dealer.

��Even if your saw is equipped with aQuickstop, a reduced kickback barand/or low kickback chain, this does noteliminate the risk of injury by kickback.Therefore, always observe all safetyprecautions to avoid kickback situations.

;�"�.��.2��.��

Some types of saw chain have speciallydesigned components to reduce theforce of nose contact kickback. STIHLhas developed low kickback chain foryour powerhead.

“Low kickback saw chain” is a chainwhich has met the kickback performancerequirements of § 5.11.2.4 ofANSI B 175.1-2000 (Safety Require-ements for Gasoli ne-Powered Chain-Saws) when tested in its originalcondition on a selected repre-sentative sample of chainsaws below3.8 cubic inch displacement specified inANSI B 175.1-2000.

� Warning! There are potential powerhead and barcombinations with which low kickbacksaw chains can be used which have notbeen specifically certified to comply withthe 45° computer derived kickback angleof § 5.11 of ANSI B 175.1-2000.Some low kickback chains have notbeen tested with all powerhead and barcombinations.

��A dull or improperly sharpened chainmay reduce or negate the effects of thedesign features intended to reduce

kickback energy. Improper lowering orsharpening of the depth gauges orshaping of the cutters may increase thechance and the potential energy of akickback. Always cut with a properlysharpened chain.

��.��.2��.�2��

STIHL green labeled reduced kickbackbars are designed to reduce the risk ofkickback injury when used with STIHLgreen labeled low kickback chains.

��When used with other, more aggressivechains, these bars may be less effectivein reducing kickback, and may result inhigher kickback forces.

#�"�(��

��Do not mount a bow guide on anySTIHL chainsaw.Any chainsaw equipped with a bowguide is potentially very dangerous.The risk of kickback is increased with abow guide because of the increasedkickback contact area. Low kickbackchain will not significantly reduce the riskof kickback injury when used on a bowguide.

��%��.��.2��.

The best protection from personal injurythat may result from kickback is to avoidkickback situations:

1. Hold the chainsaw firmly with bothhands and maintain a secure grip.

2. Be aware of the location of the guidebar nose at all times.

3. Never let the nose of the guide barcontact any object. Do not cut limbswith the nose of the guide bar.Be especially careful when cuttingsmall, tough limbs, small size brushand saplings which may easily catchthe chain.

4 Don’t overreach. 5. Don’t cut above shoulder height. 6. Begin cutting and continue at full

throttle. 7. Cut only one log at a time. 8. Use extreme caution when reentering

a previous cut. 9. Do not attempt to plunge cut if you

are not experienced with thesecutting techniques.

10. Be alert for shifting of the log or other forces that may cause the cut toclose and pinch the chain.

11. Maintain saw chain properly. Cut witha correctly sharpened, properlytensioned chain at all times.

12. Stand to the side of the cutting pathof the chainsaw.

Pull-in occurs when the chain on thebottom of the bar is suddenly stoppedwhen it is pinched, caught or encountersa foreign object in the wood. The reactionof the chain pulls the saw forward andmay cause the operator to lose control.

Pull-in frequently occurs when thebumper spike of the saw is not heldsecurely against the tree or limb andwhen the chain is not rotating at fullspeed before it contacts the wood.

��Use extreme caution when cutting smallsize brush and saplings which may easilycatch the chain and pull you off balance.

Felling is cutting down a tree.

Before felling a tree, consider carefully allconditions which may affect the directionof fall, including:

The intended direction of the fall.

The natural lean of the tree.

Any unusually heavy limb structure.

Surrounding trees and obstacles.

The wind direction and speed.

��Always observe the general condition ofthe tree. Inexperienced users shouldnever attempt to cut trees which aredecayed or rotted inside or which areleaning or otherwise under tension.There is an increased risk that such treescould snap or split while being cut andcause serious or fatal injury to theoperator or bystanders. Also look forbroken or dead branches which couldvibrate loose and fall on the operator.When felling on a slope, the operatorshould stand on the uphill side ifpossible.

When felling, maintain a distance of atleast 21/2 tree lengths from the nearestperson.

When felling in the vicinity of roads,railways and power lines, etc., take extraprecautions. Inform the police, utilitycompany or railway authority beforebeginning to cut.

��The noise of your engine may drown anywarning call.

��There are a number of factors that mayaffect and change the intended directionof fall, e.g. wind, lean of tree, slopingground, one-sided limb structure, woodstructure, decay, snow load, etc. To re-duce the risk of severe or fatal injury toyourself or others, look for these condi-tions prior to beginning the cut, and bealert for a change in direction during fall.

��

First clear the tree base and work areafrom interfering limbs and brush andclean its lower portion with an ax.

Then, establish two paths of escape (#)and remove all obstacles. These pathsshould be generally opposite to the plan-ned direction of the fall of the tree (�)and about at a 45° angle. Place alltools and equipment a safe distance awayfrom the tree, but not on the escape paths.

• Cut to no more than width of guidebar.

This is especially important in softwood in summer - it helps preventsapwood splintering when the treefalls.

• Begin 1 to 2 inches higher thancenter of felling notch

• Cut horizontalIy towards the fellingnotch

• Leave approx.1/10 of diameter uncut.This is the hinge

• Do not cut through the hinge –you could lose control of thedirection of the fall

Drive wedges into the felling cut wherenecessary to control the fall.

��If the tip of the bar contacts a wedge,it may cause kickback. Wedges shouldbe of wood or plastic – never steel,which can damage the chain.

��>��• Helps control the falling tree

��In order to reduce the risk of personalinjury, never stand directly behind thetree when it is about to fall, since part ofthe trunk may split and come backtowards the operator (barber-chairing),or the tree may jump backwards off thestump. Always keep to the side of thefalling tree. When the tree starts to fall,withdraw the bar, shut off the engine andwalk away on the preplanned escapepath. Watch out for falling limbs.

��Felling a tree that has a diameter greaterthan the length of the guide bar requiresuse of either the sectioning felling cut orplunge-cut method. These methods areextremely dangerous because theyinvolve the use of the nose of the guidebar and can result in kickback. Onlyproperly trained professionals shouldattempt these techniques.

��*��For the sectioning method make the firstpart of the felling cut with the guide barfanning in toward the hinge. Then, usingthe bumper spike as a pivot, repositionthe saw for the next cut.

Avoid repositioning the saw more thannecessary. When repositioning for thenext cut, keep the guide bar fully engagedin the kerf to keep the felling cut straight.If the saw begins to pinch, insert awedge to open the cut. On the last cut,do not cut the hinge.

First, cut a large, wide felling notch.Make a plunge cut in the center of thenotch.

The plunge cut is made with the guidebar nose. Begin the plunge cut byapplying the lower portion of the guidebar nose to the tree at an angle. Cut untilthe depth of the kerf is about the same asthe width of the guide bar. Next, alignthe saw in the direction in which therecess is to be cut.

With the saw at full throttle, insert theguide bar in the trunk.

Enlarge the plunge cut as shown inillustration.

��There is an extreme danger of kickbackat this point. Extra caution must be takento maintain control of the saw. To makethe felling cut, follow the sectioningmethod described previously.

If you are inexperienced with a chainsaw,plunge-cutting should not be attempted.Seek the help of a professional.

;�*2��Limbing is removing the branches froma fallen tree.

��There is an extreme danger of kickbackduring the limbing operation. Do notwork with the nose of the bar. Be extremelycautious and avoid contacting the log orother limbs with the nose of the guide bar.

Do not stand on a log while limbing it –you may slip or the log may roll.

Start limbing by leaving the lower limbs tosupport the log off the ground. Whenunderbucking freely hanging limbs,a pinch may result or the limb may fall,causing loss of control. If a pinch occurs,stop the engine and remove the saw,by lifting the limb.

��Be extremely cautious when cuttinglimbs or logs under tension (spring poles).The limbs or logs could spring backtoward the operator and cause loss ofcontrol of the saw and severe or fatalinjury to the operator.

#��.��Bucking is cutting a log into sections.

��1. When bucking, do not stand on the

log. Make sure the log will not rolldownhill. If on a slope, stand on theuphill side of the log.Watch out for rolling logs.

2. Cut only one log at a time.

3. Shattered wood should be cut verycarefully. Sharp slivers of woodmay be caught and flung in thedirection of the operator of the saw.

4. When cutting small logs, place logthrough “V” - shaped supports ontop of a sawhorse. Never permitanother person to hold the log.Never hold the log with your leg orfoot.

5. Logs under strain: Risk of pinching!Always start relieving cut (0) atcompression side (�).Then make bucking cut (4) attension side (#).If the saw pinches, stop the engineand remove it from the log.

6. Only properly trained professionalsshould work in an area where thelogs, limbs and roots are tangled.Working in blowdown areas isextremely hazardous.

7. Drag the logs into a clear area beforecutting. Pull out exposed and clearedlogs first.

changing the saw chain or cleaning thesaw. Do not attempt any maintenance orrepair work not described in yourOwner’s Manual. Have such work perfor-med at your STIHL service shop only.

��Never test the ignition system withignition wire terminal removed from sparkplug or with unseated spark plug, sinceuncontained sparking may cause a fire.

��To reduce the risk of fire and burn injury,use only spark plugs authorized bySTIHL. Always press spark plug bootsnugly onto spark plug terminal of theproper size. (Note: If terminal hasdetachable SAE adapter nut, it must beattached.) A loose connection betweenspark plug terminal and ignition wireconnector in the boot may create arcingthat could ignite combustible fumes andcause a fire. Keep spark plug clean, andmake sure ignition lead is in goodcondition.

��Do not operate your chainsaw if themuffler is damaged, missing or modified.An improperly maintained muffler willincrease the risk of fire and hearing loss.Never touch a hot muffler or burn will

result. If your muffler was equipped witha spark-arresting screen to reduce therisk of fire (e. g. in the USA, Canada andAustralia), never operate your saw if thescreen is missing or damaged. Remem-ber that the risk of forest fires is greaterin hot or dry weather.Keep the chain, bar and sprocket clean;replace worn sprockets or chains.Keep the chain sharp.You can spot a dull chain when easy-to-cut wood becomes hard to cut and burnmarks appear on the wood.Keep the chain at proper tension. Tightenall nuts, bolts and screws except thecarburetor adjustment screws after eachuse.

��In order for the chain brake on yourSTIHL chainsaw to properly perform itsfunction of reducing the risk of kickbackand other injuries, it must be properlymaintained. Like an automobile brake,a chainsaw chain brake incurs weareach time it is engaged.

The amount of wear will vary dependingupon usage, conditions under which thesaw is used and other factors. Excessivewear will reduce the effectiveness of thechain brake and can render it inoperable.

For the proper and effective operation ofthe chain brake the brake band andclutch drum must be kept free of dirt,grease and other foreign matter whichmay reduce friction of the band on thedrum.

For these reasons, each STIHL chain-saw should be returned to trainedpersonnel such as your STIHL servicingdealer for periodic inspection andservicing of the brake system accordingto the following schedule:Heavy usage - every three months,Moderate usage - twice a year,Occasional usage - annually.

The chainsaw should also be returnedimmediately for maintenance wheneverthe brake system cannot be thoroughlycleaned or there is a change in its operating characteristics.

Additionally, the daily maintenanceschedule for your chainsaw set forth inyour STIHL Owner’s Manual should bestrictly followed.

Store chainsaw in a dry place and awayfrom children. Before storing for longerthan a few days, always empty the fueltank (see chapter "Storing the Machine"in this manual).

For any maintenance please refer to themaintenance chart ��"��*�� near the end of this manual.

You can run chains of different pitches on this chainsaw -depending on the chain sprocket (see "Specifications"). Thechain pitch must match the guide bar. The drive link gaugemust match the guide bar groove width.

The guide bar and Oilomatic chain are supplied separately.To mount them, first unscrew the collar nut�� and - if yourmachine does not have a chain brake - take out the panhead srew �� and remove the sprocket cover ��. If youhave a Quickstop model, the chain brake must be disenga-ged before you remove the sprocket cover by pulling thehand guard toward the front handle.

Now back off the tensioning nut �� by turning the tensioningscrew �� counterclockwise until the end of its thread is levelwith the tensioning nut.

Locate the slot of the guide bar over the stud bolt �� andpush it at an angle between the clutch drum of the sprocket�� and the peg of the tensioning nut �� until the stud bolt�� is at the forward end of the slot.

To protect yourself from being injured by the sharp cuttingedges you should always wear gloves when fitting the sawchain and guide bar or tensioning and checking the chain. ��

Hold the bar nose �� up and turn the tensioning screw ��until the Oilomatic chain is properly seated on the undersideof the bar.

The Oilomatic chain is correctly tensioned when it fits snuglyagainst the underside of the bar but can still be pulled easilyalong the bar.

After finally tensioning the chain, again hold the bar nose upand securely tighten down the collar nut �� and - onmachines without chain brake - the pan head screw ��.

Chain tension and lubrication are extremely important inrespect of the cutting results obtained and the service life ofthe whole cutting attachment. Chain lubrication must alwaysbe checked before you start cutting. Chain tension shouldbe checked frequently during cutting and corrected as ne-cessary.

This engine is certified to operate onunleaded gasoline and oil with themix ratio 50:1.Your two-stroke engine requires amixture of brand-name gasoline andquality two-stroke engine oil with the��

Use regular branded unleaded gasolinewith a minimum octane rating of90 ROZ (U.S.A./Canada: pump octanemin. 89!). If the octane number of theregular grade gasoline in your area islower, use premium unleaded fuel.Fuel with a lower octane rating mayresult in preignition (causing “pinging”)which is accompanied by an increase inengine temperature. This, in turn,increases the risk of piston seizureand damage to the engine.

The chemical composition of the fuel isalso important. Some fuel additives notonly detrimentally affect elastomers(carburetor diaphragms, oil seals, fuellines etc.), but magnesium castings aswell. This could cause running problemsor even damage the engine. For thisreason it is essential that you use onlybranded fuels!Use only STIHL two-stroke engine oil orequivalent branded two-stroke air-cooled engine oils with the classificationTC for mixing.

We recommend STIHL 50:1 two-strokeengine oil since it is specially formulatedfor use in STIHL engines.Do not use BIA or TCW (two-strokewater cooled) mix oils!

Take care when handling gasoline.Avoid direct contact with the skin andavoid inhaling fuel vapour(see “Safety Precautions”).

The canister should be kept tightlyclosed in order to avoid any moisturegetting into the mixture.

The fuel tank and the canister in whichfuel mix is stored should be cleanedfrom time to time.

�� Only mix sufficient fuel for a few dayswork, not to exceed 3 months of storage.Store in approved safety fuel-canistersonly. When mixing, pour oil into thecanister first, and then add gasoline.

For automatic and reliable lubrication ofthe chain and guide bar:�� !�� " �� #�$%& �� '�� (��""��!� �� "�� "��"��#�$%& )�� "�"�

$�� Biological chain oil must beresistant to aging (e.g. STIHL Bioplus)since it will otherwise quickly turn toresin. This results in hard deposits thatare difficult to remove, especially in thearea of the chain drive, clutch and chain.It may even cause the oil pump to seize.

The service life of the chain and guidebar depends on the quality of thelubricant. It is therefore essential to useonly a specially formulated chainlubricant.

If special chain lubricant is not available,you may - in an emergency - use an HDsingle grade or multigrade engine oilwith a viscosity that suits the prevailingoutside temperature.

��Medical studies have shown thatrenewed contact with waste oil cancause skin cancer. Avoid direct contactwith waste oil. If waste oil does get onyour skin, wash with soap and water.*� �� waste oil for any purpose,and dispose of it only at authorizeddisposal locations.

• Thoroughly clean the oil filler capand the area around it to ensurethat no dirt falls into the tank.

• Refill the chain oil tank every timeyou refuel.

The choke lever is mechanically connected to the carbure-tor’s choke valve. The choke valve is closed when the chokelever is on � and open when the choke lever is moved awayfrom �.

When starting a cold engine only keep the choke slide in the� position until the engine begins to fire. Even if you do nothear the engine firing, always open the choke after pullingthe starter rope three or four times. If you leave the chokeslide in the � position, the combustion chamber will floodand stall the engine.

If you have moved the choke slide away from � after theengine has fired or after three or four pulls on the starterrope and the engine still refuses to start, you can assumethat the combustion chamber is already flooded. In such acase, remove and dry off the spark plug. With the spark plugstill removed and the stop switch on �, clear the combus-tion chamber by cranking the engine several times on thestarter. When you now try to start, move the choke leveraway from � and set the throttle trigger to the start position.The stop switch should again be moved away from �.

In very cold weather only open the choke partially after theengine begins to fire – move choke lever to about the centerposition. Allow engine to warm up for a brief period with thethrottle in the start position. Then move choke lever com-pletely away from � and disengage the starting throttlelock.

A new engine or one which has been run until the fuel tankis dry will not start first time after fueling because the fuelpump only begins to deliver sufficient fuel of the carburetorafter the engine has been turned over a few times on thestarter.

Checking chain lubrication

#��$��% ��

Every new chain has to be broken in for about 2 to 3 minutes.Ample chain lubrication is essential during this period. Afterbreaking in, stop the engine, check chain tension and adjustif necessary.

% ��&��

Never operate the chain saw without proper chain lubrica-tion. If the chain is allowed to run dry the whole cuttingattachment will be irretrievably damaged within a very shorttime. For this reason you should always check operation ofthe chain lubrication system and the level in the oil tankbefore starting work.

Start the saw and hold the cutting attachment over a lightpatch of ground. Take care – the Oilomatic chain must nottouch the ground; hold it at least 20 cm (8 in) clear of theground. Run the engine at about half throttle. If an increasingfilm of oil can be seen on the ground, chain lubrication isoperating correctly. If this is not the case, refer to "Trouble-shooting on Chain Oiling System".

'�� #��

The nose and underside of the guide bar are subject to aparticularly high rate of wear. To avoid one-sided wear, turnthe bar over every time you resharpen or preplace the chain.Regular cleaning of the oil inlet holes and guide bar grooveis also important. The bar can be examined for signs of wearat the same time.

A minimum bar groove depth must be maintained in orderto prevent the drive links contacting the bottom of the groove(the heels of the cutter and tie strap would no longer on theguide bar rails). The groove depth varies according to chaintype and pitch:

Chain type Chain pitch Minumum depth

Picco 3/8 " 5 mm (0.2")

The groove depth should be measured at the point wherethe bar is stressed most. That is the bar nose on Duromaticbars and the area where most of the cutting is done inRollomatic bars. The guide bar must be replaced whengroove depth is less than the specified minimum.

On Rollomatic guide bars it is not necessary to separatelylubricate the sprocket nose bearing because the chain oilwhich flows to the bearing by way of the bar groove duringnormal operation is adequate for lubrication.

125B

'�� #��(�% �� $��

��

Worn chain sprocket

% ��$��

The stress and strain on the chain sprocket are particularlyhigh. If the wear marks on the teeth are very pronounced(about 0.5 mm/0.02 in deep), the sprocket should bereplaced. A worn sprocket reduces the service life of thesaw chain. The chain sprocket should be replaced as amatter of routine with every second Oilomatic chain. It isbest to use saw chains alternately with one sprocket.

% ��)��

Apart from chain lubrication, chain tension is the factor thathas the greatest influence of the cutting attachment’s usefullife. It is therefore necessary to check chain tension beforestarting work and at regular short intervals during cuttingwork. Chain tension is correct in the cold condition when thechain fits snugly against the underside of the bar and canstill be pulled along the bar by hand (wear gloves!).

As it warms up to normal operating temperature the chainexpands and sags noticeably. The saw chain must beretensioned when the drive links begin to come out of thegroove on the underside of the bar. If this is not done, thereis a risk of the chain jumping off the bar.

If the chain is retensioned during cutting work it must alwaysbe slackened off again after finishing work. This is neces-sary because high contraction stresses would otherwiseoccur as the chain cools down to ambient temperature,especially at extremely low outside temperatures, andcause damage to the crankshaft and bearings.

A new chain must be retensioned more frequently than aused one because it stretches during the initial break-inperiod.

If you have checked chain lubrication (see chapter "GuideBar, Saw Chain and Chain Sprocket") and found that no oilis being delivered although the oil tank is full, switch off theengine and start looking for the fault on the cutting attach-ment.

To do this, remove the chain sprocket cover, guide barand chain. Thoroughly clean the oil inlet holes as wellas the passage between the holes and the bar groove. Alsoclean away dirt that may have collected at the end of the oilhose �� and the area around it.

Now check oil delivery again. If no oil emerges fromthe hose ��, the oil pump must be removed from themachine and cleaned.

/��"The intake air flows to the underside of the filter element. Itfollows that only the underside of the element becomesdirty. It is therefore necessary to remove the element andturn it over to check its condition.

To clean the element, first knock it out on the palm of yourhand and then wash it in non-flammable cleaning solution(warm soapy water) and blow out with compressed air ifpossible. It is best to carry a spare filter with you at all times.

The element must be replaced immediately if the felt showsany signs of damage (tears, holes).

Wrong fuel mix (too much engine oil inthe gasoline), a dirty air filter andunfavorable running conditions (mostlyat part throttle etc.) affect the condition ofthe spark plug. These factors cause deposits to form on the insulator nosewhich may result in trouble in operation.

If engine is down on power, difficult tostart or runs poorly at idling speed,first check the spark plug.

• Remove spark plug –see chapter “Starting”:

• Clean dirty spark plug.• Check electrode gap –

it should be 0.5mm/0.02" �� –readjust if necessary.
