    Because this Kombi-
    Engine is the engine for a 
    high-speed power tool, 
    special safety precau-
    tions must be observed to 
    reduce the risk of per-
    sonal injury.
    It is important that you 
    read, fully understand 
    and observe the following 
    safety precautions and 
    warnings. Read the 
    instruction manuals and 
    the safety precautions of 
    your KombiEngine and

    THE OPERATOR
    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.
    WARNING
    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.
    WARNING
    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.
    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 
    whitefinger 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 – not while using 
    KombiTool BG-KM – and keep your 
    hands warm.
    –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.
    –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.
    WARNING
    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
    WARNING
    To reduce the risk of injury, the operator 
    should wear proper protective apparel.
    WARNING
    Be particularly alert and cautious when 
    wearing hearing protection because 
    your ability to hear warnings (shouts, 
    alarms, etc.) is restricted.
    For further instructions on proper 
    clothing see the safety precautions in 
    the instruction manual of the KombiTool 
    you are using.Power tool noise may 
    damage your hearing. 
    Wear sound barriers (ear 
    plugs or ear mufflers) to 
    protect your hearing. 
    Continual and regular 
    users should have their 
    hearing checked 
    regularly.
    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.

    power tool parts see the chapter on 
    "Main Parts."
    WARNING
    Never modify this power tool in any way. 
    Only attachments supplied by STIHL or 
    expressly approved by STIHL for use 
    with the specific STIHL KombiEngine 
    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.
    THE USE OF THE POWER TOOL
    Transporting the Power Tool
    WARNING
    Always switch off the engine and make 
    sure the working tool has stopped before 
    putting a power tool down. When 
    transporting your power tool in a vehicle, 
    properly secure it to prevent turnover, 
    fuel spillage and damage to the power 
    tool.Fuel
    Your STIHL power tool uses an oil- 
    gasoline mixture for fuel (see the 
    chapter on "Fuel" of your instruction 
    manual).
    WARNING
    Fueling Instructions
    WARNING
    To reduce the risk of serious injury from 
    burns, never attempt to refuel the unit 
    until it has been completely removed 
    from the operator.
    WARNING
    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 
    allow any pressure build-up in the tank 
    t o  r e l e a s e  s l o w l y .  N e v e r  r e m o v e  t h e  f u e l  
    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 
    machine.
    WARNING
    WARNING
    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. Gasoline is an extremely 
    flammable fuel. If spilled 
    and ignited by a spark or 
    other ignition source, it 
    can cause fire and seri-
    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 combus-
    tible fuel vapor may 
    escape from the fuel 
    system.
    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 
    immediately.

    WARNING
    See also the "Fueling" chapter in your 
    Instruction Manual for additional 
    information.
    Before Starting
    WARNING
    Always check your power tool for proper 
    condition and operation before starting, 
    particularly the throttle trigger, throttle 
    trigger lockout, stop switch, cutting 
    attachment, deflector and harness. The 
    throttle trigger must move freely and 
    always spring back to the idle position. 
    Never attempt to modify the controls or 
    safety devices.
    WARNING
    Check fuel system for leaks, especially 
    the visible parts, e.g., filler cap, hose 
    connections, manual fuel pump (only for 
    power tools equipped with a manual fuel 
    pump). Do not start the engine if there 
    are leaks or damage – risk of fire! Have 
    the machine repaired by a servicing 
    dealer before using it.
    WARNING
    Never operate your power tool if it is 
    damaged, improperly adjusted or 
    maintained, or not completely or 
    securely assembled.
    WARNING
    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 
    fire.
    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.
    Starting
    Start the engine at least 10 feet (3 m) 
    from the fueling spot, outdoors only.
    For specific starting instructions, see the 
    appropriate section of your 
    KombiEngine and KombiTool manuals. 
    Place the power tool on firm ground or 
    other solid surface in an open area. 
    Maintain good balance and secure 
    footing.
    WARNING
    To reduce the risk of injury from loss of 
    control, be absolutely sure that the 
    working tool is clear of you and all other 
    obstructions and objects, including the 
    ground, because when the engine starts 
    at starting-throttle, engine speed will be 
    fast enough for the clutch to engage and 
    move the working tool.Once the engine has started, 
    immediately blip the throttle trigger, 
    which should release the starting throttle 
    and allow the engine to slow down to 
    idle.
    WARNING
    Your power tool is a one-person 
    machine. Do not allow other persons in 
    the general work area, even when 
    starting.
    WARNING
    To reduce the risk of injury from loss of 
    control, do not attempt to "drop start" 
    your power tool.
    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.
    See also the safety precautions on 
    Starting in the instruction manual of the 
    KombiTool.
    Important Adjustments
    WARNING
    To reduce the risk of personal injury 
    from loss of control or contact with the 
    running working tool, do not use a power 
    tool with incorrect idle adjustment. At 
    correct idle speed, the working tool  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.

    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.
    WARNING
    To reduce the risk of injury from loss of 
    control, never work on a ladder or on any 
    other insecure support.
    Working Conditions
    Operate and start your power tool only 
    outdoors in a well ventilated area. 
    Operate it under good visibility and 
    daylight conditions only. Work carefully.
    WARNING
    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. Control dust at the source 
    where possible. Use good work 
    practices, such as operating the unit so 
    that the wind or operating process 
    directs any dust raised by the power tool 
    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.
    Operating Instructions
    WARNING
    Do not operate your power tool using the 
    starting throttle lock, as you do not have 
    control of the engine speed.
    In the event of an emergency, switch off 
    the engine immediately – move the slide 
    control / stop switch to 0 or STOP.
    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 
    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

    (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 arrestor 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.
    WARNING
    MAINTENANCE, REPAIR AND 
    STORING
    Maintenance, replacement, or repair of 
    the emission control devices and 
    systems may be performed by any 
    nonroad engine repair establishment or 
    individual. However, if you make a 
    warranty claim for a component which 
    has not been serviced or maintained 
    properly or if nonapproved replacement 
    parts were used, STIHL may deny 
    coverage.
    WARNING
    Use only identical STIHL replacement 
    parts for maintenance and repair. Use of 
    non-STIHL parts may cause serious or 
    fatal injury.
    Strictly follow the maintenance and 
    repair instructions in the appropriate 
    section of your KombiEngine and 
    KombiTool instruction manuals. Please 
    refer to the maintenance charts 
    respectively the maintenance notes in 
    these manuals.
    WARNING
    Always stop the engine and make sure 
    that the working tool is stopped before 
    doing any maintenance or repair work or 
    cleaning the power tool. Do not attempt 
    any maintenance or repair work not 
    described in your KombiEngine and 
    KombiTool instruction manuals. Have 
    such work performed by your STIHL 
    servicing dealer only.
    WARNING
    Use the specified spark plug and make 
    sure it and the ignition lead are always 
    clean and in good condition. Always 
    press spark plug boot snugly onto spark 
    plug terminal of the proper size. (Note: If 
    terminal has detachable SAE adapter 
    nut, it must be attached.) A loose 
    connection between spark plug boot and 
    the ignition wire connector in the boot 
    may create arcing that could ignite 
    combustible fumes and cause a fire. Some STIHL power tools 
    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 power 
    tool 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.
