    9 The second recommended method for 
    starting your chain saw allows you to 
    start the saw without placing it on the 
    ground. Make sure the chain brake is 
    engaged, grip the front handle of the 
    chain saw firmly with your left hand. 
    Keep your arm on the front handle in a 
    locked (straight) position. Hold the rear 
    handle of the saw tightly between your 
    legs just above the knees. Maintain 
    good balance and secure footing. Pull 
    the starting grip slowly with your right 
    hand until you feel a definite resistance 
    and then give it a brisk, strong pull.
    WARNING
    Be sure that the guide bar and saw chain 
    are clear of you and all other 
    obstructions and objects, including the 
    ground. When the engine is started, the 
    engine speed with the starting throttle 
    lock engaged will be fast enough for the 
    clutch to engage the sprocket and, if the 
    chain brake is not activated, turn the saw 
    chain. If the upper quadrant of the tip of 
    the bar touches any object, it may cause 
    kickback to occur (see section on 
    reactive forces). To reduce this risk, 
    always engage the chain brake before 
    starting. Never attempt to start the chain 
    saw when the guide bar is in a cut or 
    kerf.Once the engine has started, 
    immediately blip the throttle trigger, 
    which should release the Master Control 
    lever to the run position and allow the 
    engine to slow down to idle.
    Always disengage chain brake before 
    accelerating engine and before starting 
    cutting work. The only exception to this 
    rule is when you check operation of the 
    chain brake. High revs with the chain 
    brake engaged (chain locked) will 
    quickly damage the powerhead and 
    chain drive (clutch, chain brake).
    WARNING
    When you pull the starter grip, do not 
    wrap the starter rope around your hand. 
    Do not let the grip snap back, but guide 
    the starter rope to rewind it properly. 
    Failure to follow this procedure may 
    result in injury to your hand or fingers 
    and may damage the starter 
    mechanism.
    Important Adjustments
    WARNING
    To reduce the risk of personal injury 
    from loss of control and / or contact with 
    the running cutting tool, do not use your 
    chain saw with incorrect idle adjustment. 
    At correct idle speed, the cutting tool 
    should not move.
    If you cannot set the correct idle speed, 
    have your STIHL dealer check your 
    chain saw and make proper adjustments 
    and repairs.Holding and Controlling the Chain Saw
    Always hold the chain saw firmly with 
    both hands when the engine is running. 
    Place your left hand on the front handle 
    bar and your right hand on the rear 
    handle and throttle trigger.
    Left-handers should follow these 
    instructions too. Wrap your fingers 
    tightly around the handles, keeping the 
    handles cradled between your thumb 
    and forefinger. With your hands in this 
    position, you can best oppose and 
    absorb the push, pull and kickback 
    forces of your saw without losing control 
    (see section on reactive forces).WARNING

    ous or fatal injury to the 
    operator or bystanders 
    from loss of control, 
    never use the chain saw 
    with one hand. It is more 
    difficult for you to control 
    reactive forces and to 
    prevent the bar and chain 
    from skating or bouncing 
    along the limb or log.

    WARNING
    To reduce the risk of cut injuries, keep 
    hands and feet away from the cutting 
    tool. Never touch a moving cutting tool 
    with your hand or any other part of your 
    body.
    WARNING
    Keep proper footing and balance at all 
    times. Special care must be taken in 
    slippery conditions (wet ground, snow) 
    and in difficult, overgrown terrain. Be 
    extremely cautious when working on 
    slopes or uneven ground. Watch for 
    hidden obstacles such as tree stumps, 
    roots, rocks, holes and ditches to avoid 
    stumbling. There is increased danger of 
    slipping on freshly debarked logs. For 
    better footing, clear away fallen 
    branches, scrub and cuttings. Use 
    extreme caution when cutting small-size 
    brush, branches and saplings because 
    slender material may catch the saw 
    chain and be whipped toward you or pull 
    you off balance.
    WARNING
    Take extreme care in wet and freezing 
    weather (rain, snow, ice). Put off the 
    work when the weather is windy, stormy 
    or rainfall is heavy.
    WARNING
    To reduce the risk of injury from loss of 
    control, never work on a ladder or any 
    other insecure support. Never hold the 
    machine above shoulder height. Do not 
    overreach.
    Position the chain saw in such a way 
    that your body is clear of the cutting 
    attachment whenever the engine is 
    running. Stand to the left of cut while 
    bucking.Never put pressure on the chain saw 
    when reaching the end of a cut. The 
    pressure may cause the bar and rotating 
    saw chain to pop out of the cut or kerf, go 
    out of control and strike the operator or 
    some other object. If the rotating saw 
    chain strikes some other object, a 
    reactive force may cause the moving 
    saw chain to strike the operator.
    STIHL recommends that first-time users 
    should cut logs on a sawhorse – see 
    "Cutting small logs."
    Working Conditions
    Operate and start your chain saw only 
    outdoors in a well-ventilated area. 
    Operate it under good visibility and 
    daylight conditions only. Work carefully.WARNING
    Your chain saw is a one-person 
    machine. Do not allow other persons in 
    the general work area, even when 
    starting. Stop the engine immediately if 
    you are approached.
    WARNING
    Even though bystanders should be kept 
    away from the running chain saw, never 
    work alone. Keep within calling distance 
    of others in case help is needed.
    WARNING
    To reduce the risk of injury to bystanders 
    and damage to property, never let your 
    chain saw run unattended. When it is not 
    in use (e. g. during a work break), shut it 
    off and make sure that unauthorized 
    persons do not use it.

    WARNING
    WARNING
    Operate your chain saw so that it 
    produces a minimum of noise and 
    emissions – do not run engine 
    unnecessarily and accelerate the engine 
    only for cutting.
    WARNING
    Use of this chain saw (including 
    sharpening the saw chain) can also 
    generate dust, mist and fumes 
    containing chemicals that are known to 
    cause respiratory problems, cancer, 
    birth defects, or other reproductive 
    harm. If you are unfamiliar with the risks 
    associated with the particular dust, mist 
    or fume at issue, consult your employer, 
    governmental agencies such as OSHA 
    and NIOSH and other sources on 
    hazardous materials. California and 
    some other authorities, for instance, 
    have published lists of substances 
    known to cause cancer, reproductive 
    toxicity, etc.
    WARNING
    Inhalation of certain dusts, especially 
    organic dusts such as mold or pollen, 
    can cause susceptible persons to have 
    an allergic or asthmatic reaction. 
    Substantial or repeated inhalation of 
    dust and other airborne contaminants, in 
    particular those with a smaller particle 
    size, may cause respiratory or other 
    illnesses. This includes wood dust, 
    especially from hardwoods, but also 
    from some softwoods such as Western 
    Red Cedar. Control dust (such as saw 
    dust), mists (such as oil mist from chain 
    lubrication) and engine fumes at the 
    source where possible. Use good work 
    practices, such as always cutting with a 
    properly sharpened saw chain (which 
    produces wood chips rather than fine 
    dust) and operating the unit so that the 
    wind or operating process directs any 
    dust raised by the chain saw away from 
    the operator. Follow the 
    recommendations of EPA/OSHA/NIOSH and occupational 
    and trade associations with respect to 
    dust ("particulate matter"). When the 
    inhalation of dust cannot be 
    substantially controlled, i.e., kept at or 
    near the ambient (background) level, the 
    operator and any bystanders should 
    wear a respirator approved by NIOSH / 
    MSHA for the type of dust encountered.
    WARNING
    Breathing asbestos dust is dangerous 
    and can cause severe or fatal injury, 
    respiratory illness or cancer. The use 
    and disposal of asbestos-containing 
    products have been strictly regulated by 
    OSHA and the Environmental Protection 
    Agency. Do not use your chain saw to 
    cut or disturb asbestos or asbestos-
    containing products. If you have any 
    reason to believe that you might be 
    cutting asbestos, immediately stop 
    cutting and contact your employer or a 
    local OSHA representative.
    Operating Instructions
    WARNING
    Do not operate your chain saw with the 
    starting throttle lock engaged. Cutting 
    with the starting throttle lock engaged 
    does not permit the operator proper 
    control of the chain saw or saw chain 
    speed. Begin and continue cutting with 
    the saw at full throttle, engage the 
    bumper spike firmly in the wood (if 
    possible) and then continue cutting. 
    Always work with the bumper spike so 
    that you have better control of the saw. If 
    you work without the bumper spike the 
    chain saw may pull you forwards 
    suddenly. As soon as the engine is 
    running, this product gen-
    erates toxic exhaust 
    fumes containing chemi-
    cals, such as unburned 
    hydrocarbons (including 
    benzene) and carbon 
    monoxide, that are 
    known to cause respira-
    tory problems, cancer, 
    birth defects, or other 
    reproductive harm. Some 
    of the gases (e. g. carbon 
    monoxide) may be color-
    less and odorless. To 
    reduce the risk of serious 
    or fatal injury/illness from 
    inhaling toxic fumes, 
    never run the machine 
    indoors or in poorly venti-
    lated locations. If exhaust 
    fumes become concen-
    trated due to insufficient 
    ventilation, clear obstruc-
    tions from work area to 
    permit proper ventilation 
    before proceeding and/or 
    take frequent breaks to 
    allow fumes to dissipate 
    before they become 
    concentrated.

    WARNING
    Never touch a saw chain with your hand 
    or any part of your body when the engine 
    is running, even when the chain is not 
    rotating.
    In the event of an emergency, switch off 
    the engine immediately – move the 
    Master Control Lever to STOP, 0 or †.
    WARNING
    Always stop the engine before putting 
    the chain saw down.
    WARNING
    The saw chain continues to move for a 
    short period after the throttle trigger is 
    released (flywheel effect).
    Accelerating the engine while the saw 
    chain is blocked increases the load and 
    will cause the clutch to slip continuously. 
    This may occur if the throttle is 
    depressed for more than a few seconds 
    when the saw chain is pinched in the cut 
    or the chain brake is engaged. It can 
    result in overheating and damage to 
    important components (e. g. clutch, 
    polymer housing components) – which 
    can then increase the risk of injury, e. g., 
    from the saw chain moving while the 
    engine is idling.
    WARNING
    Your chain saw is equipped with a chain 
    catcher. It is designed to reduce the risk 
    of personal injury in the event of a 
    thrown or broken saw chain. From time 
    to time, the catcher may be damaged or removed. To reduce the risk of personal 
    inju r y , d o not  op er at e a c h ain s a w wit h a 
    damaged or missing chain catcher.
    WARNING
    Inspect antivibration elements 
    periodically. Replace damaged, broken 
    or excessively worn antivibration 
    elements immediately, since they may 
    result in loss of control of the saw. A 
    "sponginess" in the feel of the saw, 
    increased vibration or increased 
    "bottoming" during normal operation 
    may indicate damage, breakage or 
    excessive wear. Antivibration elements 
    should always be replaced in sets. If you 
    have any questions as to whether the 
    antivibration elements should be 
    replaced, consult your STIHL servicing 
    dealer.
    If this chain saw is subjected to 
    unusually high loads for which it was not 
    designed (e. g. heavy impact or a fall), 
    always check that it is in good condition 
    before continuing work. Check in 
    particular that the fuel system is tight (no 
    leaks) and that the controls and safety 
    devices are working properly. Do not 
    continue operating this chain saw if it is 
    damaged. In case of doubt, have it 
    checked by your STIHL servicing dealer.
    Your chain saw is not designed for 
    prying or shoveling away limbs, roots or 
    other objects. Such use could damage 
    the cutting attachment or AV system.
    WARNING
    When sawing, make sure that the saw 
    chain does not touch any foreign 
    materials such as rocks, fences, nails and the like. Such objects may be flung 
    off, damage the saw chain or cause the 
    chain saw to kickback.
    WARNING
    If the rotating saw chain strikes a rock or 
    other hard object, sparks may be 
    created, which can ignite flammabale 
    materials under certain circumstances. 
    Flammable materials can include dry 
    vegetation and brush, particularly when 
    weather conditions are hot and dry. Do 
    not use your chain saw around 
    flammable materials or around dry 
    vegetation or brush when there is a risk 
    of fire or wildfire. Contact your local fire 
    authorities or the U.S. Forestry Service if 
    you have any question about whether 
    vegetation and weather conditions are 
    suitable for the use of a chain saw.
    WARNING
    Take special care when cutting 
    shattered wood because of the risk of 
    injury from slivers being caught and 
    thrown in your direction.
    WARNING
    Never modify your muffler. Any 
    modification could cause an increase in 
    heat radiation, sparks or sound level, 
    thereby increasing the risk of fire, burn 
    injury or hearing loss. You may also 
    permanently damage the engine. Have 
    your muffler serviced and repaired by 
    your STIHL servicing dealer only.
    WARNING
    The muffler and other parts of the engine 
    (e.g. fins of the cylinder, spark plug) 
    become hot during operation and remain  
    						
    							MS 441 C-M
    English
    13 hot for a while after stopping the engine. 
    To reduce risk of burns, do not touch the 
    muffler and other parts while they are 
    hot. Keep the area around the muffler 
    clean. Remove excess lubricant and all 
    debris such as pine needles, branches 
    or leaves. Let the engine cool down 
    sitting on concrete, metal, bare ground 
    or solid wood (e.g. the trunk of a felled 
    tree) away from any combustible 
    substances.
    WARNING
    An improperly mounted or damaged 
    cylinder housing or a 
    damaged/deformed muffler shell may 
    interfere with the cooling process of the 
    muffler. To reduce the risk of fire or burn 
    injury, do not continue work with a 
    damaged or improperly mounted 
    cylinder housing or a 
    damaged/deformed muffler shell.
    Your muffler is furnished with a spark 
    arresting screen designed to reduce the 
    risk of fire from the emission of hot 
    particles. Never operate your unit with a 
    missing or damaged spark arresting 
    screen. If your gas/oil mix ratio is correct 
    (i.e., not too rich), this screen will 
    normally stay clean as a result of the 
    heat from the muffler and need no 
    service or maintenance. If you 
    experience loss of performance and you 
    suspect a clogged screen, have your 
    muffler maintained by a STIHL servicing 
    dealer. Some state or federal laws or 
    regulations may require a properly 
    maintained spark arrester for certain 
    uses. See the "Maintenance, Repair and 
    Storing" section of these Safety 
    Precautions. Remember that the risk of 
    a brush or forest fire is greater in hot or 
    dry conditions.
    WARNINGDANGER
    REACTIVE FORCES INCLUDING 
    KICKBACK
    WARNING
    Reactive forces may occur any time the 
    chain is rotating. Reactive forces can 
    cause serious personal injury.
    The powerful force used to cut wood can 
    be reversed and work against the 
    operator. If the rotating saw chain is 
    suddenly and significantly slowed or  Some STIHL chain saws 
    are equipped with a cata-
    lytic converter, which is 
    designed to reduce the 
    exhaust emissions of the 
    engine by a chemical pro-
    cess in the muffler. Due 
    to this process, the muf-
    fler does not cool down 
    as rapidly as conven-
    tional mufflers when the 
    engine returns to idle or 
    is shut off. To reduce the 
    risk of fire and burn inju-
    ries when using a 
    catalytic converter, 
    always set your chain 
    saw down in the upright 
    position and never locate 
    it where the muffler is 
    near dry brush, grass, 
    wood chips or other com-
    bustible materials while it 
    is still hot.
          
            
              
                
    Do not rely on the chain 
    saw ’s insulation against 
    electric shock. To reduce 
    the risk of electrocution, 
    never operate this chain 
    saw in the vicinity of any 
    wires or cables (power, 
    etc.) which may be carry-
    ing electric current.To 
    reduce risk of electrocu-
    tion, take extra 
    precautions when cutting 
    near power lines. Have 
    the power switched off 
    before starting cutting

    14 stopped by contact with any solid object 
    such as a log or branch or is pinched, the 
    reactive forces may occur instantly. 
    These reactive forces may result in loss 
    of control, which, in turn, may cause 
    serious or fatal injury. An understanding 
    of the causes of these reactive forces 
    may help you avoid the element of 
    surprise and loss of control. Surprise 
    contributes to accidents.
    The most common reactive forces are:
    –kickback,
    –pushback,
    –pull-in.
    WARNING
    Kickback:
    When this occurs, the energy driving the 
    saw chain can create a force that moves 
    the chain saw in a direction opposite to 
    the saw chain movement at the point 
    where the saw chain is slowed or 
    stopped. This may fling the bar up and 
    back in a lightning fast reaction mainly in 
    the plane of the bar and can cause 
    severe or fatal injury to the operator.Kickback may occur, for example, when 
    the saw chain near the upper quadrant 
    of the bar nose contacts the wood or is 
    pinched during limbing or when it is 
    incorrectly used to begin a plunge or 
    boring cut.
    The greater the force of the kickback 
    reaction, the more difficult it becomes for 
    the operator to control the chain saw. 
    Many factors influence the occurrence 
    and force of the kickback reaction. 
    These include saw chain speed, the 
    speed at which the bar and saw chain 
    contact the object, the angle of contact, 
    the condition of the saw chain and other 
    factors.
    The type of bar and saw chain you use 
    is an important factor in the occurrence 
    and force of the kickback reaction. Some 
    STIHL bar and saw chain types are 
    designed to reduce kickback forces. 
    STIHL recommends the use of reduced 
    kickback bars and low kickback chains.
    Chain Saw Kickback Standard
    The following standard apply with 
    respect to kickback:
    –§ 5.11 of ANSI/OPEI B175.1-2012
    This standard, in the following referred 
    to as "the chain saw kickback standard" 
    sets certain performance and design 
    criteria related to chain saw kickback.
    To comply with the chain saw kickback 
    standard:
    a)Chain saws with a displacement of 
    less than 3.8 cubic inches (62 cm³)
    –must, in their original condition, 
    meet a 45° computer derived 
    kickback angle when equipped with 
    certain cutting attachments,
    –and must be equipped with at least 
    two devices to reduce the risk of 
    kickback injury, such as a chain 
    brake, low kickback saw chain, 
    reduced kickback bar, etc.
    b)Chain saws with a displacement of 
    3.8 cubic inches (62 cm³) and 
    above
    –must be equipped with at least one 
    device designed to reduce the risk 
    of kickback injury, such as a chain 
    brake, low kickback saw chain, 
    reduced kickback bar, etc.
    The computer derived angles for chain 
    saws below 3.8 cubic inches (62 cm³) 
    displacement are measured by applying 
    a computer program to test results from 
    a kickback test machine. Kickback may occur 
    when the moving saw 
    chain near the upper 
    quadrant of the bar nose 
    contacts a solid object or 
    is pinched.

    WARNING
    The computer derived angles of the 
    chain saw kickback standard may bear 
    no relationship to actual kickback bar 
    rotation angles that may occur in real life 
    cutting situations.
    In addition, features designed to reduce 
    kickback injuries may lose some of their 
    effectiveness when they are no longer in 
    their original condition, especially if they 
    have been improperly maintained. 
    Compliance with the chain saw kickback 
    standard does not automatically mean 
    that in a real life kickback the bar and 
    saw chain will rotate at most 45°.
    WARNING
    In order for chain saws below 3.8 cubic 
    inches (62 cm³) displacement to comply 
    with the computed kickback angle 
    requirements of the chain saw kickback 
    standard use only the following cutting 
    attachments:
    –bar and saw chain combinations 
    listed as complying in the 
    "Specifications" section of the 
    instruction manual or
    –other replacement bar and saw 
    chain combinations marked in 
    accordance with the standard for 
    use on the chain saw or
    –replacement saw chain designated 
    "low kickback saw chain."
    See the section on "Low Kickback Saw 
    Chain and Reduced Kickback Bars."Devices for Reducing the Risk of 
    Kickback Injury
    Stihl recommends the use of green 
    labeled reduced kickback bars and low 
    kickback saw chains on your chain saw 
    equipped with a Stihl Quickstop chain 
    brake.
    WARNING
    To reduce the risk of injury, never use a 
    chain saw if the chain brake does not 
    function properly. Take the chain saw to 
    your local STIHL servicing dealer. Do 
    not use the chain saw until the problem 
    has been rectified.
    STIHL Quickstop Chain Brake
    STIHL has developed a saw chain 
    stopping system designed to reduce the 
    risk of injury in certain kickback 
    situations. It is called a Quickstop chain 
    brake.There are two mechanisms for activating 
    the chain brake if it is in a properly 
    maintained condition:
    –manual activation: If a kickback 
    occurs, the chain saw moves 
    upwards towards the user in a 
    rotating motion around the front 
    handle. The brake is designed to 
    engage if the left hand contacts the 
    front guard, which is the activation 
    lever for the brake, and pushes it 
    forward.
    –inertia activation: All STIHL chain 
    saws are equipped with an interia 
    Quickstop chain brake. If the 
    kickback impulse is strong enough, 
    this alone is sufficient to engage the 
    brake even without contacting the 
    front hand guard.

    WARNING
    Never operate your chain saw without a 
    front hand guard. In a kickback situation 
    this guard helps protect your left hand 
    and other parts of your body. In addition, 
    removal of the hand guard on a chain 
    saw equipped with a Quickstop chain 
    brake will disable the activation 
    mechanism of the chain brake.
    WARNING
    No Quickstop or other chain brake 
    device prevents kickback. These 
    devices are designed to reduce the risk 
    of kickback injury, if activated, in certain 
    kickback situations. In order for the 
    Quickstop to reduce the risk of kickback 
    injury, it must be properly maintained 
    and in good working order. See the 
    chapter of your instruction manual 
    entitled "Chain Brake" and the section 
    "Maintenance, Repair and Storing" at 
    the end of these Safety Precautions. In 
    addition, there must be enough distance 
    between the bar and the operator to 
    ensure that the Quickstop has sufficient 
    time to activate and stop the chain 
    before potential contact with the 
    operator.
    WARNING
    An improperly maintained chain brake 
    may increase the time needed to stop 
    the saw chain after activation, or may 
    not activate at all.
    WARNING
    Never run the chain saw above idle 
    speed for more than 3 seconds when the 
    chain brake is engaged or when the saw chain is pinched or otherwise caught in 
    the cut. Clutch slippage can cause 
    excessive heat, leading to severe 
    damage of the motor housing, clutch 
    and oiler component and may interfere 
    with the operation of the chain brake. If 
    clutch slippage in excess of 3 seconds 
    has occurred, allow the motor housing to 
    cool before proceeding and check the 
    operation of your chain brake as 
    described in the chapter entitled "Chain 
    Brake" of your instruction manual. Also 
    make sure that the saw chain is not 
    turning at idle speed (see above at 
    "Important Adjustments").
    Low Kickback Saw Chain and Reduced 
    Kickback Bars
    STIHL offers a variety of bars and saw 
    chains. STIHL reduced kickback bars 
    and low kickback saw chains are 
    designed to reduce the risk of kickback 
    injury. Other saw chains are designed to 
    achieve higher cutting performance or 
    sharpening ease, but in turn are more 
    prone to kickback. 
    STIHL has developed a color code 
    system to help you identify the STIHL 
    reduced kickback bars and low kickback 
    saw chains. Cutting attachments with 
    green warning labels on the packaging 
    are designed to reduce the risk of 
    kickback injury. The matching of green 
    marked or labeled chain saws under 
    3.8 cubic inches (62 cm³) displacement 
    with green labeled bars and green 
    labeled saw chains gives compliance 
    with the computed kickback angle 
    requirements of the chain saw standard 
    when the products are in their original 
    condition. Products with yellow labels 
    are for users with extraordinary cutting needs, having experience and 
    specialized training for dealing with 
    kickback.
    STIHL recommends the use of its green 
    labeled reduced kickback bars, green 
    labeled low kickback saw chains and a 
    chain saw equipped with a STIHL 
    Quickstop chain brake for both 
    experienced and inexperienced chain 
    saw users.
    Please ask your STIHL dealer to 
    properly match your chain saw with the 
    appropriate bar / saw chain combination 
    to reduce the risk of kickback injury. 
    Green labeled bars and saw chains are 
    recommended for all chain saws.
    WARNING
    Use of other, non-listed bar / saw chain 
    combinations may increase kickback 
    forces and the risk of kickback injury. 
    New bar / saw chain combinations may 
    be developed after publication of this 
    literature, which will, in combination with 
    certain chain saws, comply with the 
    chain saw standard as well. Check with 
    your STIHL dealer for such 
    combinations.
    WARNING
    Reduced kickback bars and low 
    kickback saw chains do not prevent 
    kickback, but they are designed to 
    reduce the risk of kickback injury. They 
    are available from your STIHL dealer.
    WARNING
    Even if your saw is equipped with a 
    Quickstop, a reduced kickback bar and / 
    or low kickback saw chain, this does not

    17 eliminate the risk of injury by kickback. 
    Therefore, always observe all safety 
    precautions to avoid kickback situations.
    Low Kickback Saw Chain
    Some types of saw chains have 
    specially designed components to 
    reduce the force of nose contact 
    kickback. STIHL has developed low 
    kickback saw chain for your chain saw.
    A "low kickback saw chain" is a saw 
    chain that has met the kickback 
    performance requirements of 
    ANSI/OPEI B175.1-2012 when tested 
    according to the provisions specified in 
    ANSI/OPEI B175.1-2012.
    WARNING
    There are potential chain saw and bar 
    combinations with which low kickback 
    saw chains can be used which have not 
    been specifically certified to comply with 
    the 45° computer derived kickback 
    angle of the chain saw standard. Some 
    low kickback saw chains have not been 
    tested with all chain saw and bar 
    combinations.
    WARNING
    A blunt or incorrectly sharpened saw 
    chain may reduce or negate the effects 
    of the design features intended to 
    reduce kickback energy. Improper 
    lowering or sharpening of the depth 
    gauges as well as changing the shape of 
    the cutters may increase the risk and the 
    energy of kickback. Always cut with a 
    properly sharpened saw chain.Reduced Kickback Bars
    STIHL green labeled reduced kickback 
    bars are designed to reduce the risk of 
    kickback injury when used with STIHL 
    green labeled low kickback saw chains.
    WARNING
    When used with other, more aggressive 
    saw chains, these bars may be less 
    effective in reducing kickback.
    WARNING
    For a properly balanced saw and in 
    order to comply with the chain saw 
    standard, use only bar lengths listed in 
    the specifications chapter of the 
    instruction manual for your chain saw.
    To avoid kickback
    The best protection from personal injury 
    that may result from kickback is to avoid 
    kickback situations:
    1.Hold the chain saw firmly with both 
    hands and maintain a secure grip. 
    Don’t let go.
    2.B e  a w a r e  o f  t h e  l o c ation of the guide 
    bar nose at all times.
    3.Never let the nose of the guide bar 
    contact any object. Do not cut limbs 
    with the nose of the guide bar. Be 
    especially careful near wire fences 
    and when cutting small, tough 
    limbs, small size brush and saplings 
    which may easily catch the saw 
    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 these 
    cutting techniques.
    10.Be alert for shifting of the log or 
    other forces that may cause the cut 
    to close and pinch the saw chain.
    11.Maintain saw chain properly. Cut 
    with a correctly sharpened, properly 
    tensioned saw chain at all times.
    12.Stand to the side of the cutting path 
    of the chain saw.
    Bow Guides
    WARNING
    Do not mount a bow guide on any STIHL 
    chain saw. Any chain saw equipped with 
    a bow guide is potentially very 
    dangerous. The risk of kickback is 
    increased with a bow guide because of 
    the increased kickback contact area. 
    Low kickback saw chain will not 
    significantly reduce the risk of kickback 
    injury when used on a bow guide.

    A=Pull-in
    Pull-in occurs when the saw chain on the 
    bottom of the bar is suddenly stopped 
    when it is pinched, caught or encounters 
    a foreign object in the wood. The 
    reaction of the saw chain pulls the chain 
    saw forward and may cause the 
    operator to lose control.
    Pull-in frequently occurs when the 
    bumper spike of the chain saw is not 
    held securely against the tree or limb 
    and when the saw chain is not rotating at 
    full speed before it contacts the wood.
    WARNING
    Use extreme caution when cutting small 
    size brush and saplings which may 
    easily catch the saw chain, be whipped 
    towards you or pull you off balance.
    To avoid pull-in
    1.Always start a cut with the saw 
    chain rotating at full speed and the 
    bumper spike in contact with the 
    wood.
    2.The risk of pull-in may also be 
    reduced by using wedges to open 
    the kerf or cut.
    B = Pushback
    Pushback occurs when the saw chain on 
    the top of the bar is suddenly stopped 
    when it is pinched, caught or encounters 
    a foreign object in the wood. The 
    reaction of the saw chain may drive the 
    chain saw rapidly straight back toward 
    the operator and may cause loss of 
    chain saw control, which, in turn, may 
    cause serious or fatal injury. Pushback 
    frequently occurs when the top of the bar 
    is used for cutting.
    To avoid pushback
    1.Be alert to forces or situations that 
    may cause material to pinch the top 
    of the saw chain.
    2.Do not cut more than one log at a 
    time.
    3.Do not twist the chain saw when 
    withdrawing the bar from a plunge 
    cut or underbuck cut because the 
    saw chain can pinch.
    Limbing
    Limbing is removing the branches from a 
    fallen tree.
    WARNING
    There is an extreme danger of kickback 
    during the limbing operation. Do not 
    work with the nose of the bar. Be 
    extremely cautious and avoid contacting 
    the log or other 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 
    to support the log off the ground. When 
    underbucking 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.
    WARNING
    Be extremely cautious when cutting 
    limbs or logs under tension (spring 
    poles). The limbs or logs could spring 
    back toward the operator and cause loss 
    of control of the saw and severe or fatal 
    injury to the operator.
