    Reactive forces, including kickback, can 
    be dangerous. Pay special attention to 
    the section on reactive forces.
    Have your STIHL dealer show you how 
    to operate your power tool. All safety 
    precautions that are generally observed 
    when working with an ax or a hand saw 
    also apply to the operation of chain 
    saws. Observe all applicable federal, 
    state and local safety regulations, 
    standards and ordinances. When using 
    a chain saw for logging purposes, for 
    instance, refer to the OSHA regulations 
    for "logging operations" at 29 Code of 
    Federal Regulations 1910.266.
    Do not lend or rent your power tool 
    without the instruction manual. Be sure 
    that anyone using it understands the 
    information contained in this manual.
    The use of this machine may be 
    hazardous.The saw chain has many 
    sharp cutters. If the cutters contact your 
    flesh, they will cut you, even if the chain 
    is not moving.
    Use your chain saw only for cutting 
    wooden objects.
    Do not use it for other purposes, since 
    misuse may result in personal injury or 
    property damage, including damage to 
    the machine.
    Minors should never be allowed to use 
    this power tool. Bystanders, especially 
    children, and animals should not be 
    allowed in the area where it is in use.
    To reduce the risk of injury to bystanders 
    and damage to property, never let your 
    power tool 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.
    Most of these safety precautions and 
    warnings apply to the use of all STIHL 
    chain saws. Different models may have 
    different parts and controls. See the appropriate section of your instruction 
    manual for a description of the controls 
    and the function of the parts of your 
    Safe use of a chain saw involves
    1the operator
    2the power tool
    3the use of the power tool.
    Physical Condition
    You must be in good physical condition 
    and mental health and not under the 
    influence of any substance (drugs, 
    alcohol, etc.) which might impair vision, 
    dexterity or judgment. Do not operate 
    this machine when you are fatigued.
    Be alert – if you get tired, take a break. 
    Tiredness may result in loss of control. 
    Working with any power tool can be 
    strenuous. If you have any condition that 
    might be aggravated by strenuous work, 
    check with your doctor before operating 
    this machine.
    Prolonged use of a power tool (or other 
    machines) exposing the operator to 
    vibrations may produce whitefinger 
    disease (Raynaud's phenomenon) or 
    carpal tunnel syndrome.
    Safety Precautions and 
    Working Techniques
    Because a chain saw is a 
    high-speed, fast-cutting 
    power tool, special safety 
    precautions must be 
    observed to reduce the 
    risk of personal injury.
    It is important that you 
    read, fully understand 
    and observe the following 
    safety precautions and 
    warnings. Read the 
    instruction manual and 
    the safety precautions 
    periodically. Careless or 
    improper use may cause 
    serious or fatal injury. 
    							MS 210, MS 210 C, MS 230, MS 230 C, MS 250, MS 250 C
    4 These conditions reduce the hand's 
    ability to feel and regulate temperature, 
    produce numbness and burning 
    sensations and may cause nerve and 
    circulation damage and tissue necrosis.
    All factors which contribute to white-
    finger disease are not known, but cold 
    weather, smoking and diseases or 
    physical conditions that affect blood 
    vessels and blood transport, as well as 
    high vibration levels and long periods of 
    exposure to vibration are mentioned as 
    factors in the development of whitefinger 
    disease. In order to reduce the risk of 
    whitefinger disease and carpal tunnel 
    syndrome, please note the following:
    –Most STIHL power tools are 
    available with an anti-vibration 
    ("AV") system designed to reduce 
    the transmission of vibrations 
    created by the machine to the 
    operator's hands. An AV system is 
    recommended for those persons 
    using power tools on a regular or 
    sustained basis.
    –Wear gloves and keep your hands 
    warm. Heated handles, which are 
    available on some STIHL 
    powerheads, are recommended for 
    cold weather use.
    –Keep the AV system well 
    maintained. A power tool with loose 
    components or with damaged or 
    worn AV elements will tend to have 
    higher vibration levels. Keep the saw chain sharp. A dull chain will 
    increase cutting time, and pressing 
    a dull chain through wood will 
    increase the vibrations transmitted 
    to your hands.
    –Maintain a firm grip at all times, but 
    do not squeeze the handles with 
    constant, excessive pressure. Take 
    frequent breaks.
    All the above-mentioned precautions do 
    not guarantee that you will not sustain 
    whitefinger disease or carpal tunnel 
    syndrome. Therefore, continual and 
    regular users should closely monitor the 
    condition of their hands and fingers. If 
    any of the above symptoms appear, 
    seek medical advice immediately.
    The ignition system of the STIHL unit 
    produces an electromagnetic field of a 
    very low intensity. This field may 
    interfere with some pacemakers. To 
    reduce the risk of serious or fatal injury, 
    persons with a pacemaker should 
    consult their physician and the 
    pacemaker manufacturer before 
    operating this tool.
    Proper Clothing
    To reduce the risk of injury, the operator 
    should wear proper protective apparel.Clothing must be sturdy 
    and snug-fitting, but allow 
    complete freedom of 
    movement. Wear long 
    pants made of heavy 
    material to help protect 
    your legs from contact 
    with branches or brush. 
    To reduce the risk of cut 
    injuries, wear pants or 
    chaps that contain pads 
    of cut retardant material. 
    Avoid loose-fitting jack-
    ets, scarfs, neckties, 
    jewelry, flared or cuffed 
    pants, unconfined long 
    hair or anything that 
    could become caught on 
    branches, brush or the 
    moving parts of the unit. 
    Secure hair so it is above 
    shoulder level.
    Good footing is very 
    important. Wear sturdy 
    boots with nonslip soles. 
    Steel-toed safety boots 
    are recommended.
    Wear an approved safety 
    hard hat to reduce the 
    risk of injury to your head. 
    Chain saw noise may 
    damage your hearing. 
    Wear sound barriers (ear 
    plugs or ear mufflers) to 
    help protect your hearing. 
    Continual and regular 
    users should have their 
    hearing checked 
    							MS 210, MS 210 C, MS 230, MS 230 C, MS 250, MS 250 C
    5 Be particularly alert and cautious when 
    wearing hearing protection because 
    your ability to hear warnings (shouts, 
    alarms, etc.) is restricted.
    Never operate your power tool unless 
    wearing goggles or properly fitted 
    protective glasses with adequate top 
    and side protection complying with ANSI 
    Z 87.1 (or your applicable national 
    standard). To reduce the risk of injury to 
    your face STIHL recommends that you 
    also wear a face shield or face screen 
    over your goggles or protective glasses.
    For illustrations and definitions of the 
    power tool parts see the chapter on 
    "Main Parts."
    Never modify this power tool in any way. 
    Only attachments supplied by STIHL or 
    expressly approved by STIHL for use 
    with the specific STIHL model are 
    authorized. Although certain 
    unauthorized attachments are useable 
    with STIHL power tools, their use may, 
    in fact, be extremely dangerous.
    If this tool 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 machine if it is damaged. 
    In case of doubt, have it checked by your 
    STIHL servicing dealer.
    Transporting the Power Tool
    To reduce the risk of injury from saw 
    chain contact, never carry or transport 
    your power tool with the saw chain 
    moving. Always engage the chain brake 
    when taking more than a few steps.
    Always switch off the engine, and fit the 
    chain guard (scabbard) over the chain 
    and guide bar before transporting the 
    power tool over longer distances. When 
    transporting it in a vehicle, properly 
    secure it to prevent turnover, fuel 
    spillage and damage to the unit.
    It may be carried only in a horizontal 
    position. Grip the front handle in a 
    manner that the machine is balanced horizontally. Keep the hot muffler away 
    from your body and the cutting 
    attachment behind you.
    Your STIHL power tool uses an oil- 
    gasoline mixture for fuel (see the 
    chapter on "Fuel" of your instruction 
    Fueling Instructions
    Fuel your power tool in well-ventilated 
    areas, outdoors. Always shut off the 
    engine and allow it to cool before 
    refueling. Gasoline vapor pressure may 
    build up inside the fuel tank depending 
    on the fuel used, the weather conditions 
    and the tank venting system.
    In order to reduce the risk of burns and 
    other personal injury from escaping gas 
    vapor and fumes, remove the fuel filler 
    cap on your power tool carefully so as to  Always wear gloves 
    when handling the 
    machine and the cutting 
    tool. Heavy-duty, nonslip 
    gloves improve your grip

    ous burn injury or 
    property damage. Use 
    extreme caution when 
    handling gasoline or fuel 
    mix. Do not smoke or 
    bring any fire or flame 
    near the fuel or the power 
    tool. Note that combusti-
    ble fuel vapor may 
    escape from the fuel 
    							MS 210, MS 210 C, MS 230, MS 230 C, MS 250, MS 250 C
    6 allow any pressure build-up in the tank 
    to release slowly. Never remove the fuel 
    filler cap while the engine is running.
    Select bare ground for fueling and move 
    at least 10 feet (3 m) from the fueling 
    spot before starting the engine. Wipe off 
    any spilled fuel before starting your 
    In order to reduce the risk of fuel spillage 
    and fire from an improperly tightened 
    fuel cap, correctly position and tighten 
    the fuel cap in the fuel tank opening.
    Different models may be equipped with 
    different fuel caps.Toolless cap with grip
    To do this with this STIHL cap, raise the 
    grip on the top of the cap until it is upright 
    at a 90° angle. Insert the cap in the fuel 
    tank opening with the raised positioning 
    marks on the grip of the cap and on the 
    fuel tank opening lining up. Using the 
    grip, press the cap down firmly while 
    turning it clockwise as far as it will go 
    (approx. 1/4 turn).
    Misaligned, damaged or broken cap
    NIf the cap does not drop fully into the 
    opening when the positioning marks 
    line up and/or if the cap does not 
    tighten properly when twisted, the 
    base of the cap may be prematurely 
    rotated (in relation to the top) to the 
    closed position. Such misalignment can result from handling, cleaning 
    or an improper attempt at 
    NTo return the cap to the open 
    position for installation, turn the cap 
    (with the grip up) until it drops fully 
    into the tank opening. Next, twist the 
    cap counterclockwise as far as it will 
    go (approx. 1/4 turn) – this will twist 
    the base of the cap into the correct 
    position. Then, twist the cap 
    clockwise, closing it normally.
    NIf your cap still does not tighten 
    properly, it may be damaged or 
    broken; immediately stop use of the 
    unit and take it to your authorized 
    STIHL dealer for repair. Check for fuel leakage 
    while refueling and during 
    operation. If fuel leakage 
    is found, do not start or 
    run the engine until the 
    leak is fixed and any 
    spilled fuel has been 
    wiped away. Take care 
    not to get fuel on your 
    clothing. If this happens, 
    change your clothing 
    Fold the grip flush with 
    the top of the cap. Grip 
    the cap and check for 
    tightness. If the grip does 
    not lie completely flush 
    with the cap and the 
    detent on the grip does 
    not fit in the correspond-
    ing recess in the filler 
    opening, or if the cap is 
    loose in the filler opening, 
    the cap is not properly 
    seated and tightened and

    See also the "Fueling" chapter in your 
    Instruction Manual for additional 
    Before Starting
    Take off the chain guard (scabbard) and 
    inspect the saw for proper condition and 
    operation. (See the maintenance chart 
    near the end of the instruction manual.)
    Always check your power tool for proper 
    condition and operation before starting, 
    particularly the throttle trigger, throttle 
    trigger lockout, stop switch and cutting 
    tool. The throttle trigger must move 
    freely and always spring back to the idle 
    position. Never attempt to modify the 
    controls or safety devices.
    Never operate your power tool if it is 
    damaged, improperly adjusted or 
    maintained, or not completely or 
    securely assembled.
    Check that the spark plug boot is 
    securely mounted on the spark plug – a 
    loose boot may cause arcing that could 
    ignite combustible fumes and cause a 
    For proper assembly of the bar and 
    chain follow the procedure described in 
    the chapter "Mounting the Bar and 
    Chain" of your instruction manual. 
    STIHL Oilomatic chain, guide bar and 
    sprocket must match each other in 
    gauge and pitch. Before replacing any 
    bar and chain, see the chapter entitled 
    "Specifications" in the instruction 
    manual and the section "Kickback" and 
    the "ANSI B 175.1-2000 chain saw 
    chain saw kickback standard" below.
    Proper tension of the chain is extremely 
    important. In order to avoid improper 
    setting, the tensioning procedure must 
    be followed as described in your 
    manual. Always make sure the 
    hexagonal nut(s) for the sprocket cover 
    is (are) tightened securely after 
    tensioning the chain in order to secure 
    the bar. Never start the saw with the 
    sprocket cover loose. Check chain 
    tension once more after having 
    tightened the nut(s) and thereafter at 
    regular intervals (whenever the saw is 
    shut off). If the chain becomes loose while cutting, shut off the engine and 
    then tighten. Never try to adjust the 
    chain while the engine is running!
    Keep the handles clean and dry at all 
    times; it is particularly important to keep 
    them free of moisture, pitch, oil, fuel mix, 
    grease or resin in order for you to 
    maintain a firm grip and properly control 
    your power tool.
    To reduce the risk of fire and burn 
    injuries, start the engine at least 10 feet 
    (3 m) from the fueling spot, outdoors 
    Start and operate your saw without 
    assistance. For specific starting 
    instructions, see the appropriate section 
    of the instruction manual. Proper starting 
    methods reduce the risk of injury.
    To reduce the risk of injury from chain 
    contact and / or reactive forces, the 
    chain brake must be engaged when 
    starting the saw.
    Do not drop start. This method is very 
    dangerous because you may lose 
    control of the saw.
    There are two recommended methods 
    for starting your chain saw. Unit vibrations can cause 
    an improperly tightened 
    fuel filler cap to loosen or 
    come off and spill quanti-
    ties of fuel. In order to 
    reduce the risk of fuel 
    spillage and fire, tighten 
    the fuel filler cap by hand 
    as securely as possible. 
    							MS 210, MS 210 C, MS 230, MS 230 C, MS 250, MS 250 C
    8 With the first recommended method, the 
    chain saw is started on the ground. 
    Make sure the chain brake is engaged 
    (see "Chain Brake" chapter in your 
    instruction manual) and place the chain 
    saw on firm ground or other solid surface 
    in an open area. Maintain good balance 
    and secure footing.
    Grip the front handlebar of the saw firmly 
    with your left hand and press down. For 
    saws with a rear handle level with the 
    ground, put the toe of your right foot into 
    the rear handle and press down. With 
    your right hand pull out the starter grip 
    slowly until you feel a definite resistance 
    and then give it a brisk, strong pull.
    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.
    Be sure that the guide bar and 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 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 
    As soon as the engine is running, 
    immediately blip the throttle trigger, 
    which will disengage the starting throttle 
    lock and allow the engine to settle down 
    to idle.
    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
    To reduce the risk of personal injury 
    from loss of control and / or contact with 
    the running cutting tool, do not use your 
    unit with incorrect idle adjustment. At 
    correct idle speed, the cutting tool 
    should not move. For directions on how 
    to adjust idle speed, see the appropriate 
    section of your instruction manual.
    If you cannot set the correct idle speed, 
    have your STIHL dealer check your 
    power tool and make proper 
    adjustments and repairs.
    During Operation
    Holding and Controlling the Power Tool
    Always hold the unit firmly with both 
    hands on the handles while you are 
    working. Wrap your fingers and thumbs 
    around the handles.
    Your right hand should grip the rear 
    handle. This also applies to left-handers. 
    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
