    –To replace the chain
    –For remedying malfunctions
    Observe sharpening instructions – for 
    safe and proper handling, always keep 
    the chain and guide bar in flawless 
    condition. Keep the chain properly 
    sharpened, tensioned and well 
    Change chain, guide bar and chain 
    sprocket in due time.
    Regularly check that the clutch drum is 
    in perfect working condition.
    Always store fuel and chain lubricant 
    only in the specified type of containers 
    and ensure they are correctly labelled. 
    Store in a dry, cool and secure place 
    protected against light and sunlight.
    In the event of a chain brake 
    malfunction, switch off the machine 
    immediately – risk of injury! Consult a 
    servicing dealer – do not use the 
    machine until the malfunction has been 
    remedied, see "Chain brake".The most common reactive forces that 
    occur during cutting are: kickback, 
    pushback and pull-in.
    Dangers of kickback
    Kickback occurs when the saw is 
    suddenly thrown up and back in an 
    uncontrolled arc towards the operator.
    Kickback occurs, e.g.
    –when the upper quadrant of the bar 
    nose unintentionally contacts wood 
    or another solid object, e.g. when 
    another limb is touched accidentally 
    during limbing.
    –when the chain at the nose of the 
    guide bar is pinched in the cut.
    QuickStop chain brake:
    This device reduces the risk of injury in 
    certain situations – it cannot prevent 
    kickback. If activated, the brake stops 
    the saw chain within a fraction of a 
    second –
    for a description of this device refer to 
    chapter on "Chain Brake" in this manual.
    To reduce the risk of kickback
    –Work cautiously and avoid 
    situations which could cause 
    –Hold the saw firmly with both hands 
    and maintain a secure grip.
    –Always cut at full throttle.
    –Be aware of the location of the guide 
    bar nose at all times.
    Reactive Forces
    Kickback can result in 
    serious or fatal injury.

    10 –Do not cut with the bar nose.
    –Take special care with small, tough 
    limbs, they may catch the chain.
    –Never cut several limbs at once.
    –Do not overreach.
    –Never cut above shoulder height.
    –Use extreme caution when re-
    entering a previous cut.
    –Do not attempt plunge cuts if you 
    are not experienced in this cutting 
    –Be alert for shifting of the log or 
    other forces that may cause the cut 
    to close and pinch the chain.
    –Always cut with a correctly 
    sharpened, properly tensioned 
    chain – the depth gauge setting 
    must not be too large.
    –Use a low kickback chain and a 
    narrow radius guide bar.
    Pull-in (A)
    Pull-in occurs when the chain on the 
    bottom of the bar is suddenly pinched, 
    caught or encounters a foreign object in 
    the wood. The reaction of the chain pulls 
    the saw forward – to reduce this risk, 
    always engage the spiked bumper 
    securely in the tree or limb.
    Pushback (B)
    Pushback occurs when the chain on the 
    top of the bar is suddenly pinched, 
    caught or encounters a foreign object in 
    the wood. The reaction of the chain 
    drives the saw straight back toward the 
    operator – to avoid this risk:
    –Be alert to situations that may cause 
    the top of the guide bar to be 
    –Do not twist the guide bar in the cut.
    Do not operate your saw in the starting 
    throttle position. Engine speed cannot 
    be controlled with the throttle trigger in 
    this position.
    Work calmly and carefully – in daylight 
    conditions and only when visibility is 
    good. Ensure you do not endanger 
    others – stay alert at all times.
    Use the shortest possible guide bar: The 
    chain, guide bar and chain sprocket 
    must match each other and your saw.
    Position the saw so that your body is 
    clear of the cutting attachment.

    11 If conditions allow, work from a lift 
    Never work on a ladder or on any other 
    insecure support, do not work above 
    shoulder height.
    Cordon off the work area in order to 
    reduce the risk of injuries and damage to 
    property from falling branches (e.g. 
    motor vehicles).
    When working with a lifeline there is a 
    risk of cutting through the rope – to 
    reduce the risk of fall injuries, always 
    use double lifelines.
    Take special care when cutting through 
    a limb. Hold the machine firmly to control 
    and counteract the feed force. Note 
    when reaching the end of a cut that the 
    saw is no longer supported in the kerf. 
    You have to take the full weight of the 
    saw – increased risk of accidents.Make sure your saw does not touch any 
    foreign materials: Stones, nails, etc. may 
    be flung off and damage the saw chain. 
    The saw may kick back unexpectedly – 
    risk of accidents.
    If the rotating chain makes contact with 
    a rock or other solid object there is a risk 
    of sparking which may cause easily 
    combustible material to catch fire under 
    certain circumstances. Dry plants and 
    scrub are also easily combustible, 
    especially in hot and dry weather 
    conditions. If there is a risk of fire, do not 
    use your chainsaw near combustible 
    materials, dry plants or scrub. Always 
    contact your local forest authority for 
    information on a possible fire risk.
    Do not underbuck freely hanging limbs 
    because the chain may get pinched and 
    cause kickback and loss of control.
    Take care when cutting scrub and young 
    trees. The saw chain may catch and 
    throw thin shoots in your direction.
    To reduce the risk of injury, take special 
    care when cutting shattered wood 
    because of the risk of injury from slivers 
    being caught and thrown in your 
    After finishing a cut, activate the chain 
    brake to lock the chain or shut off the 
    engine before moving the saw to 
    another position in the tree.Cutting techniques:
    Always start the cut with the engine at 
    full throttle.
    Always pull the saw out of the cut with 
    the chain running.
    –Cut straight through thin limbs
    –In case of thick limbs, first perform 
    relieving cut from below (approx. 1/5 
    of diameter), then buck from above
    –Support and secure heavy 
    branches with ropes.
    If the saw gets pinched in the cut:
    –Shut off the engine and secure the 
    saw to the tree – in direction of 
    –Carefully free the saw from the cut, 
    using another saw if necessary.
    Limbs under tension:
    Always start relieving cut (1) at the 
    compression side (A).
    NMake relieving cut (1) and then 
    perform bucking cut (2) at the 
    tension side (B) – the saw will 
    otherwise pinch or kick back.
    If not otherwise possible, make the 
    bucking cut from the bottom upwards 
    (underbuck) – be wary of pushback.

    12 A cutting attachment consists of the saw 
    chain, guide bar and chain sprocket.
    The cutting attachment that comes 
    standard is designed to exactly match 
    the chain saw.
    –The pitch (t) of the saw chain (1), 
    chain sprocket and the nose 
    sprocket of the Rollomatic guide bar 
    must match.
    –The drive link gauge (2) of the saw 
    chain (1) must match the groove 
    width of the guide bar (3).
    If non-matching components are used, 
    the cutting attachment may be damaged 
    beyond repair after a short period of 
    Disengaging the Chain Brake

    gasoline and engine oil.
    For health reasons, avoid direct skin 
    contact with gasoline and avoid inhaling 
    gasoline vapor.
    STIHL MotoMix
    STIHL recommends the use of STIHL 
    MotoMix. This ready-to-use fuel mix 
    contains no benzol or lead, has a high 
    octane rating and ensures that you 
    always use the right mix ratio.
    STIHL MotoMix uses STIHL HP Ultra 
    two-stroke engine oil for an extra long 
    engine life. 
    MotoMix is not available in all markets.
    Mixing Fuel
    Unsuitable fuels or lubricants or mix 
    ratios other than those specified may 
    result in serious damage to the engine. 
    Poor quality gasoline or engine oil may 
    damage the engine, sealing rings, hoses 
    and the fuel tank.
    Use only high-quality brand-name 
    gasoline with a minimum octane rating 
    of 90 – leaded or unleaded.If your machine is equipped with a 
    catalytic converter, you must use 
    unleaded gasoline.
    A few tankfuls of leaded gasoline will 
    greatly reduce the efficiency of the 
    catalytic converter.
    Gasoline with an ethanol content of 
    more than 10% can cause running 
    problems in engines with a manually 
    adjustable carburetor and should not be 
    used in such engines.
    Engines equipped with M-Tronic deliver 
    full power when run on gasoline with an 
    ethanol content of up to 25% (E25).
    Engine oil
    Use only high-quality two-stroke engine 
    oil – preferably STIHL HP, HP Super or 
    HP Ultra, which are specially formulated 
    for use in STIHL engines. HP Ultra 
    guarantees high performance and a 
    long engine life.
    These engine oils are not available in all 
    Use only STIHL 50:1 two-stroke engine 
    oil for the fuel mix in models with a 
    catalytic converter.
    Mix Ratio

    NUse a canister approved for storing 
    fuel. Pour oil into canister first, then 
    add gasoline and mix thoroughly.
    Storing Fuel
    Store fuel only in approved safety-type 
    fuel canisters in a dry, cool and safe 
    location protected from light and the sun.
    Fuel mix ages – only mix sufficient fuel 
    for a few weeks work. Do not store fuel 
    mix for longer than 30 days. Exposure to 
    light, the sun, low or high temperatures 
    can quickly make the fuel mix unusable.
    STIHL MotoMix may be stored for up to 
    2 years without any problems.
    NThoroughly shake the mixture in the 
    canister before fueling your 
    Pressure may build up in the canister – 
    open it carefully.

    the chain and guide bar – use only an 
    environmentally compatible quality 
    chain and bar lubricant. Rapidly 
    biodegradable STIHL BioPlus is 
    Biological chain oil must be resistant to 
    aging (e.g. STIHL BioPlus),  since it will 
    otherwise quickly turn to resin. This 
    results in hard deposits that are difficult 
    to remove, especially in the area of the 
    chain drive and chain. It may even cause 
    the oil pump to seize.
    The service life of the chain and guide 
    bar depends on the quality of the 
    lubricant. It is therefore essential to use 
    only a specially formulated chain 
    Do not use waste oil. Renewed contact 
    with waste oil can cause skin cancer. 
    Moreover, waste oil is environmentally 
    Waste oil does not have the necessary 
    lubricating properties and is unsuitable 
    for chain lubrication.
    Preparing the machine
    NThoroughly clean the filler cap and 
    the area around it to ensure that no 
    dirt falls into the tank

    18 If the oil tank is still partly full, the reason 
    may be a problem in the oil supply 
    system: Check chain lubrication, clean 
    the oil passages, contact your servicing 
    dealer for assistance if necessary. 
    STIHL recommends that maintenance 
    and repair work be carried out only by 
    authorized STIHL dealers.
    The saw chain must always throw off a 
    small amount of oil.
    Never operate your saw without chain 
    lubrication. If the chain runs dry, the 
    whole cutting attachment will be 
    irretrievably damaged within a very short 
    time. Always check chain lubrication and 
    the oil level in the tank before starting 
    Every new chain has to be broken in for 
    about 2 to 3 minutes.
    After breaking in the chain, check chain 
    tension and adjust if necessary – see 
    "Checking Chain Tension".
    Locking the Chain
    –in an emergency
    –when starting
    –at idling speed
    The chain brake is activated by pushing 
    the hand guard toward the bar nose with 
    your left hand – or by inertia in certain 
    kickback situations: The chain is 
    stopped and locked.
