    NOTE!
    The machine is fitted with a two-stroke engine and must
    always be run on a mixture of petrol and two-stroke oil. It is
    important to measure the quantity of oil accurately, to ensure
    the correct mixture ratio. Small discrepancies in the amount of
    oil have a great bearing on the proportions of the fuel mixture
    when mixing small amounts of fuel.
    Petrol
    NOTE!
    Always use an oil-mixed
    quality petrol (at least 90
    octane). If your machine is
    equipped with a catalytic
    converter, (see “technical
    data”) an unleaded, oil
    mixed quality petrol
    should always be used. A
    leaded petrol will destroy
    the catalytic converter
    •The lowest
    recommended octane
    rating is 90. If you run
    the engine on a petrol
    with a lower octane
    rating than 90 so-called
    “knocking“ can occur.
    This leads to an
    increased engine
    temperature, which can
    result in a serious engine
    breakdown.
    •When working at
    continuous high revs a
    higher octane rating is
    recommended.
    WARNING!
     Always provide good ventilation when
    handling fuel.
    !
    •Clean around the fuel
    cap. Contamination in
    the tank can disrupt
    operations.
    •Ensure that the fuel is
    well mixed by shaking the
    container before filling
    the tank.
    !
    WARNING!
    The catalytic converter muffler gets very hot
    during and after use. This also applies
    during idling. Be aware of the fire hazard,
    especially when handling the saw near
    flammable substances or vapours.
    Fuelling
    WARNING!
    The following precautions reduce the risk
    of fire:
    Do not smoke or place any sources of heat
    in the vicinity of the fuel. Never refuel
    when the engine is running. Always stop
    the engine and let it cool for a few minutes
    before refuelling. Open the fuel cap slowly
    when fuelling so that any over pressure is
    released slowly. Tighten the fuel cap
    carefully after refuelling. Always move the
    machine from the fuelling place before
    starting.
    !
    Two-stroke oil
    •For the best results use HUSQVARNA two-stroke oil,
    which has been specially produced for clearing saws and
    chain saws.
    Mixing ratio 1:50 (2%).
    •If HUSQVARNA two-stroke oil is not available you can use
    a high quality two-stroke oil intended for air cooled engines.
    Contact your dealer when selecting an oil.
    Mixing ratio: 1:33 (3%).
    •Never use two-stroke oil intended for water cooled outboard
    motors, so-called outboard motor oil.
    •Never use oil intended of four-stroke engines.
    Min. 3 m
    (10 ft)
    Mixture
    •Always mix petrol and oil in a clean container intended for
    petrol.
    •Always start by filling half the quantity of petrol required.
    Then add the entire oil quantity. Mix (shake) the fuel
    mixture. Fill the remaining quantity of petrol.
    •Mix (shake) the fuel mixture carefully before filling in the
    machine‘s fuel tank.
    •Do not mix more than max. one month’s supply of fuel.
    •If the machine is not used for a long period of time, the fuel
    tank should be emptied and cleaned.

    START AND STOP
    Control before starting
    For reasons of safety follow
    these recommendations!
    •Check that the support
    flange is not cracked due to
    fatigue or due to being
    tightened too much.
    Discard the support flange
    if it is cracked.
    •Ensure the locking nut has
    not lost its captive force.
    The nut lock should have a
    locking force of at least 1.5
    Nm. The tightening
    torque of the locking nut
    should be 35-50 Nm.
    •Check that the trimmer
    head and spray guard are
    not damaged or cracked.
    Replace the trimmer head
    or spray guard if they are
    exposed to impact or are
    cracked.
    •Never use the machine
    without a guard or spray
    guard nor with a defective
    guard.
    !
    WARNING!
    The complete clutch cover with shaft must
    be fitted before the machine is started,
    otherwise the clutch can become loose
    and cause personal injury.
    Always move the machine from the filling
    area before starting. Place the machine on
    a flat surface. Ensure the cutting
    equipment cannot come into contact with
    any object. Make sure no unauthorised
    persons are in the working area,
    otherwise there is a risk of serious
    personal injury. The safety distance is 15
    metres.
    Start and stop
    WARNING!
    When the engine is started with the choke
    in the choke or start position the cutting
    equipment starts to rotate immediately.
    !
    Start
    Press the machine body
    against the ground using
    your left hand (NOTE! Not
    your foot). Grip the starter
    handle, slowly pull out the
    cord with your right hand
    until you feel some
    resistance (the starter pawls
    grip), now quickly and
    powerfully pull the cord.
    Reset the choke control as
    soon as the engine fires and
    repeat until the engine starts.
    When the engine starts
    quickly apply full throttle
    and the start throttle will
    automatically disengage.
    NOTE! Do not pull the
    starter cord out completely
    and do not release the starter
    cord from the fully extended
    position. This can damage
    the machine.
    Cold engine
    IGNITION:
    Set the stop switch to the
    start position.
    CHOKE:
    Set the choke control in the
    choke position.
    AIR PURGE:
    Press the air purge
    diaphragm repeatedly until
    fuel begins to fill the
    diaphragm. The  diaphragm
    need not be completely
    filled.
    Warm engine
    Use the same starting
    procedure as for the cold
    engine, but do not set the
    choke control in the choke
    position. The start throttle
    position is obtained by
    setting the choke control in
    the choke position and then
    returning it to its original
    position.
    Stop
    The engine is stopped by
    switching off the ignition.

    Basic setting
    •The carburettor is set to its basic setting when test run at the
    factory. The basic setting is richer than the optimal setting
    and should be kept during the machine‘s first working
    hours. Thereafter the carburettor should be finely adjusted.
    Fine adjustment should be carried out by a skilled
    technician.
    NOTE! If the cutting attachment rotates/moves while the
    engine is idling the T-screw should be turned anti-clockwise
    until the cutting attachment stops.
    Rec. idling speed: 2 700 rpm.
    Recommended max. speed: See “Technical Data” .
    !
    WARNING!
    The complete clutch cover with shaft
    must be fitted before the machine is
    started, otherwise the clutch can become
    loose and cause personal injury.
    Operation
    •The carburettor governs
    the engine‘s speed via the
    throttle. Air/fuel is mixed
    in the carburettor. The
    air/fuel mixture is
    adjustable. To take
    advantage of the engine‘s
    optimal output the
    adjustment must be
    correct.
    •The setting of the
    carburettor means that
    the engine is adapted to
    local conditions, for
    example, the climate,
    altitude, petrol and the
    type of 2-stroke oil.
    •The carburettor is
    equipped with three
    adjustment possibilities:
    L = Low speed needle
    H = High speed needle
    T = Idle speed adjuster
       screw
    •The fuel quantity in relation to the air flow permitted by
    the throttle opening is adjusted using the L and H-needles.
    Turning the needles clockwise gives a leaner fuel mixture
    (less fuel) and turning them anti-clockwise gives a richer
    fuel mixture (more fuel). A leaner mixture gives high revs
    while a richer mixture give less revs.
    •The T-screw regulates the position of the throttle while the
    engine is idling. Turning the screw clockwise gives a higher
    idling speed while turning it anti-clockwise gives a lower
    idling speed.
    Fine adjustment
    •When the machine has been ”run-in” the carburettor should
    be finely adjusted. The fine adjustment should be carried
    out by qualified person.  First adjust the L-jet, then the
    idling screw T and then the H-jet.
    Conditions
    •Before any adjustments are made the airfilter should be clean
    and the airfilter cover fitted. Adjusting the carburettor while
    a dirty airfilter is in use will result in a leaner mixture when
    the filter is finally cleaned. This can give rise to serious
    engine damage.
    •Carefully turn the L and H needle to the mid point between
    fully turned in and fully turned out.
    •Do not attempt to adjust the needles beyond the stops as
    damage can occur.
    •Now start the machine according to the starting instructions
    and run it warm for 10 minutes.
    NOTE! If the cutting attachment rotates/moves the T screw
    should be turned anti-clockwise until the cutting attachment
    stops.
    Low speed needle L
    Try to find the highest idling
    speed, turning the low speed
    needle L clockwise
    respectively counter-
    clockwise. When the highest
    speed has been found, turn
    the low speed needle L 1/4
    turn counter-clockwise.
    NOTE! If the cutting
    attachment rotates/moves in
    the idling position, turn the
    idling speed screw T
    counter-clockwise until the
    cutting attachment stops.
    !
    WARNING!
    If the idling speed cannot be adjusted so
    that the cutting attachment stops,
    contact your service workshop. Do not
    use the machine until it has been
    correctly adjusted or repaired.
    MAINTENANCE
    Carburettor
    Your Husqvarna product has been designed and
    manufactured to specifications that reduce harmful
    emissions.
    After your unit has been run 8-10 tanks of fuel the engine
    has broken in. To ensure that your unit is at peak
    performance and producing the least amount of harmful
    emissions after break in, have your authorized servicing
    dealer, who has a revolution counter at his disposal, to adjust
    your carburettor for optimum operating conditions.

    MAINTENANCE
    H
    needle. The high speed needle is adjusted correctly when the
    machine ‘splatters’ a little . If the machine smokes heavily at
    the same time as it ‘splatters’ heavily the adjustment is too rich. The high speed needle
    affects the machine’s power,
    speed, temperature and fuel
    consumption. A too lean
    adjustment on the high
    speed needle H (the high
    speed needle H is screwed
    in too much) gives a too
    high speed resulting in
    engine damage. Do not
    allow the engine to run at
    full speed for more than 10
    seconds.
    Apply full throttle and turn
    the high speed needle H
    slowly anticlockwise until
    the engine runs unevenly.
    The high speed needle H is
    then turned slowly
    clockwise a little until the
    engine runs smoothly.
    Note the engine should be
    run unloaded when
    adjusting the high speed
    needle.  Therefore
    dismantle the cutting
    equipment, nut, support
    flange and disc drive before
    adjusting the high speed
    Final setting of the idling speed T
    Adjust the idling speed with
    the screw T, if it is necessary
    to readjust. First turn the
    idle speed adjusting screw T
    clockwise until the cutting
    attachment starts to rotate/
    move.
    Then turn, counter-
    clockwise until the cutting
    attachment stops. A correctly
    adjusted idle speed setting
    occurs when the engine runs
    smoothly in every position.
    It should also be good
    margin to the rpm when the
    cutting attachment starts to
    rotate/move.
    CAUTION! Contact your servicing dealer, if the idle speed
    setting cannot be adjusted so that the cutting attachment
    stops. Do not use the machine until it has been properly
    adjusted or repaired.
    NOTE! For optimum setting of the carburettor, contact a
    qualified servicing dealer who has a revolution counter at his
    disposal.
    High speed needle HCorrectly adjusted carburettor
    A correctly adjusted carburettor means that the machine
    accelerates without hesitation and the machine 4-cycles a
    little at max speed. Furthermore, the cutting attachment
    must not rotate/move at idling. A too lean adjusted low
    speed needle L may cause starting difficulties and bad
    acceleration.
    A too lean adjusted high speed needle H gives lower power
    = less capacity, bad acceleration and/or damage to the
    engine.
    A too rich adjustment of the two speed needles L and H
    gives acceleration problems or too low working speed.

    MAINTENANCE
    Cooling system
    To maintain as low opera-
    ting temperature as possible
    the engine is equipped with
    a cooling system.
    The cooling system consists
    of:
    1. An air intake on the
    starter unit.
    2. Cooling fins on the
    flywheel.
    3. Cooling fins on the
    cylinder
    4. Cylinder cover (leads cold
    air onto the cylinder).
    Muffler
    NOTE!
    Some mufflers are fitted with a catalytic converter. See
    “Technical data” to see whether your machine is fitted with a
    catalytic converter.
    The muffler is designed to
    dampen the noise level and
    to direct the exhaust fumes
    away from the user. The
    exhaust fumes are hot and
    can contain sparks, which
    can result in fire if the
    exhaust fumes are directed
    towards a dry and
    inflammable material. Some
    mufflers are equipped with a
    special spark arrest screen. If
    your machine is fitted with
    this type of screen it should
    be cleaned regularly. This is
    done using a wire brush. On
    mufflers without a catalytic
    converter the screen should
    be cleaned weekly, or
    replaced if necessary. On
    mufflers fitted with a
    catalytic converter the
    screen should be checked
    and cleaned monthly. If the
    screen is damaged it should
    be replaced. If the screen is
    frequently blocked, this can
    be a sign that the function
    of the catalytic converter is
    impaired. Contact your
    dealer to inspect the muffler.
    A blocked screen will cause
    the engine to overheat
    resulting in damage to the
    cylinder and piston. Also see
    under “Maintenance”.
    NOTE!
    Never use a machine with a defective muffler.
    !
    WARNING!
    Mufflers fitted with catalytic converters
    become extremely hot during use and
    after stopping. This also applies at idling
    speeds. Contact can result in burns to
    the skin. Be observant to the risk of fire!

    Spark plug
    The condition of the spark
    plug is affected by:
    •An incorrect carburettor
    setting.
    •An incorrect fuel
    mixture (too much or
    faulty oil).
    •A dirty air filter.
    These factors cause
    deposits on the spark plug
    electrode that may result in
    malfunction or starting
    difficulties.
    If the machine is low on power, difficult to start or runs
    poorly while idling always check the spark plug first.
    If the spark plug is dirty, clean it and at the same time check
    that the electrode gap is 0.5 mm. The spark plug should be
    changed after about one month of operation or earlier if
    necessary.
    NOTE! Always use the recommended type of spark plug. An
    incorrect spark plug can damage the cylinder/piston.
    0,5 mm
    Clean the cooling system using a brush at least once a week, in
    difficult conditions more often.
    A dirty or blocked cooling system leads to the engine
    overheating resulting in damage to the cylinder and piston.
    The end of the drive axle in
    the lower shaft should be
    lubricated with grease every

    9The angle gear is filled with a
    sufficient quantity of grease at
    the factory. However, before
    using the machine you should
    check that the angle gear is
    filled to 3/4 with grease. Use
    HUSQVARNA special
    grease.
    Normally, the grease does not
    need to be changed except
    when repairs are carried out.
    Air filter
    The air filter should be
    cleaned regularly removing
    dust and dirt to avoid:
    •carburettor malfunction
    •starting problems
    •reduced engine power
    •unnecessary wear to
    engine parts
    •abnormal fuel
    consumption
    Clean the filter after every
    25 hours or more regularly
    if operating conditions are
    exceptionally dusty.
    Cleaning the air filter
    Dismantle the air filter cover and remove the air filter. Wash in
    clean, warm soapy water. Ensure that the filter is dry before
    refitting. An air filter used for a long period of time can never
    be cleaned completely. Therefore it is necessary to replace the
    filter from time to time with a new filter. A damaged air filter
    must always be replaced.
    If the machine is used in dusty conditions the air filter
    should be soaked in oil, see the section on “Oiling the air
    filter“.
    Oiling the air filter
    Always use HUSQVARNA
    filter oil, order no. 503 47
    73-01. The filter oil
    contains a solvent to make it
    spread evenly through the
    filter. You should therefore
    avoid skin contact. Put the
    filter in a plastic bag and the
    pour the filter oil over it.
    Knead the plastic bag to
    distribute the oil. Squeeze
    the excess oil out of the filter
    inside the plastic bag and
    pour off the excess before
    fitting the filter on the machine. Never use common engine
    oil. This would drain through the filter quite quickly and
    collect in the bottom.
