    							5EN3. Installing Guide Bar and Saw Chain
    A standard saw unit package contains the items
    as illustrated.
    Open the box and install the guide bar and the
    saw chain on the power unit as follows:
    The saw chain has very
    sharp edges. Use thick protective gloves for
    safety.
    1. Pull the guard towards the front handle to
    check that the chain brake is not engaged.
    2. Loosen the nuts and remove the chain cover.
    3. Gear the chain to the sprocket and, while fit-
    ting the saw chain around the guide bar,
    mount the guide bar to the power unit. Adjust
    the position of chain tensioner nut.
    !WARNING!
    Pay attention to the correct
    direction of the saw chain.
    4. Fit the chain cover to the power unit and fas-
    ten the nuts to finger tightness.
    5. While holding up the tip of the bar, adjust the
    chain tension by turning the tensioner screw
    until the tie straps just touch the bottom side
    of the bar rail.
    6. Tighten the nuts securely with the bar tip held
    up (12 ~ 15 Nm). Then check the chain for
    smooth rotation and proper tension while
    moving it by hand. If necessary, readjust with
    the chain cover loose.
    7. Tighten the tensioner screw.
    A new chain will expand its
    length in the beginning of use. Check and read-
    just the tension frequently as a loose chain can
    easily derail or cause rapid wear of itself and the
    guide bar.

    							6MM6EN4. Fuel and Chain Oil
    • FUEL
    Gasoline is very flamma-
    ble. Avoid smoking or bringing any flame or
    sparks near fuel. 
    Make sure to stop the engine and allow it cool
    before refueling the unit. 
    Select outdoor bare ground for fueling and
    move at least 3 m (10 ft) away from the fuel-
    ing point before starting the engine.
    •The engines are lubricated by oil specially for-
    mulated for air-cooled 2-cycle gasoline engine
    use. Use an anti-oxidant added quality oil
    expressly labeled for air-cooled 2-cycle engine
    use (JASO FC GRADE OIL or ISO EGC
    GRADE).
    •Do not use BIA or TCW (2-stroke water-cool-
    ing type) mixed oil.
    •RECOMMENDED MIXING RATIO GASO-
    LINE 50: OIL 1
    •Exhaust emission are controlled by the funda-
    mental engine parameters and components
    (eq., carburation, ignition timing and port tim-
    ing) without addition of any major hardware or
    the introduction of an inert material during
    combustion.
    •These engines are certified to operate on
    unleaded gasoline.
    •Make sure to use gasoline with a minimum
    octane number of 89RON (USA/Canada:
    87AL).
    •If you use a gasoline of a lower octane value
    !WARNING!
    than prescribed, there is a danger that the
    engine temperature may rise and an engine
    problem such as piston seizing may conse-
    quently occur.
    •Unleaded gasoline is recommended to reduce
    the contamination of the air for the sake of
    your health and the environment.
    •Poor quality gasolines or oils may damage
    sealing rings, fuel lines or fuel tank of the
    engine.
    •HOW TO MIX FUEL
    Pay attention to agitation.
    1. Measure out the quantities of gasoline and oil
    to be mixed.
    2.Put some of the gasoline into a clean,
    approved fuel container.
    3. Pour in all of the oil and agitate well.
    4. Pour in the rest of gasoline and agitate again
    for at least one minute. As some oils may be
    difficult to agitate depending on oil ingredi-
    ents, sufficient agitation is necessary for the
    engine to last long. Be careful that, if the agi-
    tation is insufficient, there is an increased
    danger of early piston seizing due to abnor-
    mally lean mixture.
    5. Put a clear indication on the outside of the
    container to avoid mixing up with gasoline or
    other containers.
    6. Indicate the contents on outside of container
    for easy identification.
    •FUELING THE UNIT
    1. Untwist and remove the fuel cap. Rest the
    cap on a dustless place..
    2. Put fuel into the fuel tank to 80% of the full
    capacity.
    3. Fasten the fuel cap securely and wipe up any
    fuel spillage around the unit.
    !WARNING!
    4. Fuel and Chain Oil  
    						
    							7EN4. Fuel and Chain Oil
    1. Select flat and bare ground for fueling.
    2. Move at least 10 feet (3 meters) away from
    the fueling point before starting the
    engine.
    3. Stop the engine before refueling the unit.
    At that time, be sure to sufficiently agitate
    the mixed gasoline in the container.
    •FOR YOUR ENGINE LIFE, AVOID:
    1. FUEL WITH NO OIL (RAW GASOLINE) – It will
    cause severe damage to the internal engine
    parts very quickly.
    2. GASOHOL – It can cause deterioration of
    rubber and/or plastic parts and disruption of
    engine lubrication.
    3. OIL FOR 4-CYCLE ENGINE USE – It can
    cause spark plug fouling, exhaust port block-
    ing, or piston ring sticking.
    4.
    Mixed fuels which have been left unused
    for a period of one monthor more may clog
    the carburetor and result in the engine failing
    to operate properly.
    5. In the case of storing the product for a long
    period of time, clean the fuel tank after ren-
    dering it empty. Next, activate the engine and
    empty the carburetor of the composite fuel.
    6. In the case of scrapping the used mixed oil
    container, scrap it only at an authorized
    repository site.
    Moreover, normal wear and
    change in product with no functional influence
    are not covered by the warranty. Also, be careful
    that, if the usage in the instruction manual is not
    observed as to the mixed gasoline, etc.
    described therein, it may not be covered by the
    warranty.
    •CHAIN OIL
    Only use special oil for chain
    saws or adhesive oil for chain saws. Do not use
    oil containing impurities so as not to block the oil
    filter and to prevent irreparable damage to the oil
    pump.
    The special oil for lubricating
    the chain is biodegradable. Use of a mineral oil
    or engine oil causes serious damage to the envi-
    ronment.
    IMPORTANT
    IMPORTANT
    NOTE
    !WARNING!It is essential that you use good quality oil to
    lubricate the cutting parts effectively. Used or
    poor quality oil does not guarantee good lubri-
    cation and reduces the duration of the chain and
    bar.
    It is always worth topping up the oil tank com-
    pletely (using a funnel) every time you refuel.
    Since the oil tank capacity is enough to guaran-
    tee that the fuel runs out first, you will avoid the
    risk of operating the machine without lubricant. 
    						
    							8MM8EN5. Operating the Engine
    It is very dangerous to run
    a chainsaw that mounts broken parts or lacks
    any parts. Before starting engine, make sure
    that all the parts including bar and chain are
    installed properly.
    •STARTING THE ENGINE
    1. Fill fuel and chain oil tanks respectively, and
    tighten the caps securely.
    2. Set the switch to “I” position.
    3. While holding the throttle lever together with
    the trigger safety, push in the side latch and
    release the throttle lever to leave it at the
    starting position.
    !WARNING!When restarting immediately
    after stopping the engine, set the Choke knob in
    the first-stage position (choke open and throttle
    lever in the starting position).
    Once the choke knob has
    been pulled out, it will not return to the operating
    position even if you press down on it with your
    finger. When you wish to return the choke knob
    to the operating position, pull out the throttle
    lever instead.
    4.
    If your machine has aprimer (3), press it 3-
    4 times to aid starting.
    5. While holding the saw unit securely on the
    ground, pull the starter rope vigorously.
    Do not start the engine
    while the chain saw hangs in one hand. The
    saw chain may touch your body. This in very
    dangerous.
    6. When engine has ignited, first push in the
    choke knob to the first-stage position and
    then pull the starter again to start the engine.
    7. Allow the engine to warm up with the throttle
    lever pulled slightly.
    Keep clear of the saw
    chain as it will start rotating upon starting of
    engine.
    •CHECKING THE OIL SUPPLY 
    Make sure to set up the bar
    and the chain when checking the oil supply.
    If not, the rotating parts may be exposed. It is
    very dangerous.
    After starting the engine, run the chain at medi-
    um speed and see if chain oil is scattered off as
    shown in the figure.

    							9EN5. Operating the Engine
    The chain oil flow can be changed by inserting a
    screwdriver in the hole on bottom of the clutch
    side.  Adjust according to your work conditions.
    The oil tank should become
    nearly empty by the time fuel is used up. Be sure
    to refill the oil tank every time when refueling the
    saw.
    •ADJUSTING THE CARBURETOR
    The carburetor has been adjusted at the factory.
    Should your unit need readjustment due to the
    changes in altitude or operating conditions,
    please let your skillful dealer make the adjust-
    ment. 
    A wrong adjustment may cause damage to your
    unit. 
    If you have to make the adjustment yourself,
    please follow the procedure below carefully.
    Before adjusting the carburetor, make sure that
    the provided air/fuel filters are clean and fresh
    and the fuel properly mixed.
    NOTE
    When adjusting, take the following steps:
    Be sure to adjust the carbu-
    retor with the bar chain attached.
    1. “H” and “L” needles are restricted within the
    number of turn as shown below.
    “H” needle: -1/4
    “L” needle: -1/4
    2. Start the engine and allow it to warm up in
    low speed for a few minutes.
    3. Turn the idle adjusting screw (T) counter-
    clockwise so that the saw chain does not
    turn. If the idling speed is too slow, turn the
    screw clockwise.
    4. Make a test cut and adjust the “H” needle for
    best cutting power, not for maximum speed.
    Over revolution of “H” needle
    causes a lack of power or a poor acceleration. In
    such a case please turn the “H” needle a little
    counterclockwise.
    •CHAIN BRAKE
    This machine is equipped with an automatic
    brake tostop saw chain rotation upon occur-
    rence of kickback during saw cutting.
    The brake is automatically operated by inertial
    force, which acts on the weight fitted inside the
    front guard.
    This brake can also be operated manually with
    the front guard turned down to the guide bar.
    To release the brake, pull up the front guard
    toward the front handle till a “click” sound is
    heard.
    CautionBe sure to confirm brake operation during daily
    inspection.

    2. Run up the engine to maximum revs. Grip the
    chain saw by the front handgrip and push the
    hand guard forwards with the thumb, in the
    direction of the bar. 
    Release the accelerator lever when the brake is
    engaged. The chain must stop immediately as
    soon as the brake is engaged.
    If the brake is not working correctly, contact your
    dealer for a check and repair.
    The clutch will overheat if the engine remains at
    a high number of revs with the brake engaged.
    This can lead to damage to the clutch and the
    brake belt.
    Release the accelerator lever immediately if the
    brake is engaged when working.
    •CARBURETOR ANTI-FREEZE MECHANISM
    Operating chain saws in temperatures of 0 – 5°C
    at times of high humidity may result in ice form-
    ing within the carburetor, and this in turn may
    cause the output power of the engine to be
    reduced or for the engine to fail to operate
    smoothly.
    This product has accordingly been designed
    with a ventilation hatch on the right side of the
    surface of the cylinder cover to allow warm air to
    be supplied to the engine and to thereby prevent
    icing from occurring.
    Under normal circumstances the product should
    be used in the normal operating mode, i.e., in the
    mode which it is set at the time of shipment.However when the possibility exists that icing
    may occur, the unit should be set to operate in
    the anti-freeze mode before use
    Continuing to use the prod-
    uct in the anti-freeze mode even when tempera-
    tures have risen and returned to normal, may
    result in the engine failing to start properly or in
    the engine failing to operate at its normal speed,
    and for this reason you should always be sure to
    return the unit to the normal operating mode if
    there is no danger of icing occurring.
    HOW TO SWITCH BETWEEN OPERATING
    MODES
    1. Flip the engine switch to turn off the engine.
    2. Remove the cover to the air filter, remove the
    air filter, and then remove the choke knob from
    the cylinder cover.
    3. Loosen the screws holding the cylinder cover
    in place (i.e., the three screws on the inside
    and the one screw on the outside of the
    cover), and then remove the cylinder cover.
    4. Press with your finger down on the icing cap
    located on the right-hand side of the cylinder
    cover to remove the icing cap.
    5. Adjust the icing cap so that the “snow” mark
    faces upwards and then return it to its original
    position in the cylinder cover.
    6. Fix the cylinder cover back into its original
    position, and then fix all other parts back into
    their proper positions.
    •STOPPING THE ENGINE
    1. Release the throttle lever to allow the engine
    to idle for a few minutes
    2. Set the switch to the “O” (STOP) position.

    							11EN6. Sawing
    •Before proceeding to
    your job, read the sec-
    tion “For Safe Oper-
    ation”. It is recommend-
    ed to first practice saw-
    ing easy logs. This also
    helps you get accus-
    tomed to your unit.
    •Always follow the safety
    regulations. The chain
    saw must only be used
    for cutting wood. It is
    forbidden to cut other
    types of material.
    Vibrations and kickback
    vary with different mate-
    rials and the require-
    ments of the safety reg-
    ulations would not be
    respected. Do not use
    the chain saw as a lever
    for lifting, moving or
    splitting objects. Do not
    lock it over fixed stands.
    It is forbidden to hitch
    tools or applications to
    the PTO other than
    those specified by the
    manufacturer.
    •
    It is not necessary to force the saw into the
    cut. Apply only light pressure while running the
    engine at full throttle.
    •When the saw chain is caught in the cut, do
    not attempt to pull it out by force, but use a
    wedge or a lever to open the way.
    •GUARD AGAINST KICKBACK
    !WARNING!•This saw is equipped with
    a chain brake that will
    stop the chain in the
    event of kickback if oper-
    ating properly. You must
    check the chain brake
    operation before each
    usage by running the saw
    at full the throttle for 1-2
    seconds and pushing the
    front hand guard forward.
    The chain should stop
    immediately with the
    engine at full speed. If the
    chain is slow to stop or
    does not stop, replace the
    brake band and clutch
    drum before use.
    •It is extremely important
    that the chain brake be
    checked for proper oper-
    ation before each use and
    that the chain be sharp in
    order to maintain the kick-
    back safety level of this
    saw. Removal of the safe-
    ty devices, inadequate
    maintenance, or incorrect
    replacement of the bar or
    chain may increase the
    risk to serious personal
    injury due to kickback.
    •FELLING A TREE
    1. Decide the felling direction considering the
    wind, lean of the tree, location of heavy
    branches, ease of completing the task after
    felling and other factors.
    2.While clearing the area around the tree,
    arrange a good foothold and retreat path.

    (3) Felling direction
    6. Sawing   
    						
    							12MM12EN6. Sawing
    3. Make a notch cut one-third of the way into
    the tree on the felling side.
    4. Make a felling cut from the opposite side of
    the notch and at a level slightly higher than
    the bottom of the notch.
    When you fell a tree, be
    sure to warn neighboring workers of the dan-
    ger.
    Bucking and Limbing
    •Always ensure your foothold. Do not stand
    on the log.
    •Be alert to the rolling over of a cut log.
    Especially when working on a slope, stand
    on the uphill side of the log.
    •Follow the instructions in “For Safe
    Operation” to avoid kickback of the saw.
    Before starting work, check the direction of
    bending force inside the log to be cut. Always
    finish cutting from the opposite side of the bend-
    ing direction to prevent the guide bar from being
    caught in the cut.
    A log lying on the ground
    Saw down halfway, then roll the log over and cut
    from the opposite side.
    A log hanging off the ground
    In area “A”, saw up from the bottom one-third
    and finish by sawing down from the top. In area
    “B”, saw down from the top one-third and finish
    by sawing up from the bottom.
    !WARNING!
    !WARNING!Cutting the limbs of Fallen Tree
    First check to which side the limb is bent. Then
    make the initial cut from the bent side and finish
    by sawing from the opposite side.
    Be alert to the springing
    back of a cut limb.
    Pruning of Standing Tree
    Cut up from the bottom, finish down from the
    top.
    •Do not work standing on unstable bases or
    rung ladders.
    •Do not overreach.
    •Do not cut above shoulder height.
    •Always use both your hands to hold the
    saw.

    Before cleaning, the
    inspecting or repairing the unit, make sure
    that engine has stopped and is cool.
    Disconnect the spark plug to prevent acci-
    dental starting.
    •MAINTENANCE AFTER EACH USE
    1. Air filter
    Loosen the knob and remove the air cleaner
    cover. 
    Take off the filter element and brush off attached
    sawdust. When the filter is clogged with dust,
    separate it in halves and shake-wash with gaso-
    line.
    When using compressed air, blow from the
    inside.
    To assemble the cleaner halves, press the rim
    until it clicks.
    When installing the main filter, make sure that the
