    6.3.3 ADJUSTMENT TO THE ENGAGEMENT AND BRAKE OF THE BLADES
    When the blade disengagement lever is
    operated, it also brings the blade brake
    into operation which stops the blades
    within few seconds.
    A stretched cable and changes in the
    length of the belt can impair the blades’
    engagement or rotation. 
    To compensate this, turn the adjuster (1)
    until the correct spring length (2) is
    achieved (measured from the outer ends of the springs with the blades
    engaged).
    6.3.4 B
    RAKE ADJUSTMENT
    Should the brakes work poorly, consult a Licensed Service Centre immediately.
    6.3.5 A
    DJUSTING THE TENSION OF THE DRIVE BELT
    Should you notice a drop in forward drive
    power, adjust the tension of the spring of
    the stretcher to return to former condi-
    tions.
    The adjustment is made by opening the
    engine hood to reach the right side of the
    engine.
    Turn the nuts (2) as much as necessary
    to reach length “A” of the spring (1) of:
    A= 119 - 121  mm (For mechanical drive models)
    A= 120 - 122  mm (For hydrostatic drive models)
    measured to the outside of the end of the spring. When the adjustment has
    been made, tighten the nuts (2).

    When replacing the belt, take great care when using for the
    first few times as engagement may be sudden until the belt is sufficiently run in.
    6.4 DISMANTLING AND REPLACEMENT
    6.4.1 R
    EPLACING WHEELS
    Stop the machine on a flat surface and put a block under a load-bearing part of
    the frame on the side that the wheel is to
    be changed.
    The wheels are held by a snap ring (1)
    which can be eased off with a screwdriv-
    er.
    The rear wheels are directly coupled to
    the differential axle shaft and fastened by
    a key that forms part of the wheels hub.
    Should you substitute one or both rear wheels, ensure that
    they are of the same diameter, and check that cutting deck is horizontal to pre-
    vent an uneven cut.
    Before refitting a wheel, smear some waterproof grease on
    the axle and carefully refit the snap ring (1) and washer (2).
    6.4.2 R
    EPLACING AND REPAIRING TYRES
    The tyres are of the «Tubeless» type and therefore all puncture repairs will have
    to be carried out by a tyre-repair expert in accordance with the methods for this
    kind of tyre.

    							6.4.3 REPLACING BULBS( if fitted)
    The bulbs (18W) have a bayonet fitting and are
    installed in the bulb holder which can be taken out
    by turning it anti-clockwise, using pliers.
    6.4.4 R
    EPLACING A FUSE
    The machine is fitted with fuses (1) with different
    capacities and functions. Specifically:
    – 6.3 A (delayed) fuse (1) = protects the main and
    power circuits of the electronic board. When it
    blows, the machine stops and the dashboard
    light switches off.
    – 25 A fuse (2) = protects the battery charger cir-
    cuit. When it blows, the battery gradually runs
    out and the machine will have problems start-
    ing.
    The fuse capacity is indicated on the fuse.
    A blown fuse must always be replaced by one of the same
    type and ampere rating, and never with one of another rating.
    If you cannot find out why the fuse has blown, consult a Licensed Service Cen-
    tre.
    6.4.5 R
    EPLACING BELTS
    Replacing belts is quite a complicated process of dismantling and subsequent
    adjustment and must only be carried out by a Licensed Service Centre.
    Replace the belts as soon as they show obvious signs of
    wear! ALWAYS USE GENUINE REPLACEMENT BELTS!

    For towing a small trailer.
    3. CLOTH COVER
    Protects the machine from dust when not in use.
    4.
    CB01 MAINTENANCE BATTERY-CHARGER
    This makes it possible to keep the battery in good
    working order when the machine is in storage,
    guaranteeing an optimum level of charge and a
    longer life to the battery.
    5. “MULCHING” KIT
    It finely chops the grass cuttings and leaves it on
    the lawn, as an alternative to lateral ejection.
