IMPORTANT Check that the two rear wheels
are the same height (fig. 48.A) and that the
difference between the external diameters of
the two wheels (fig. 48.B) is no greater than
8-10 mm. On the contrary, to avoid uneven
mowing, the cutting device assembly must be
aligned by an Authorised Service Centre.
8.3.5 Repairing or changing tyres
Every replacement or repair of a tyre following
a puncture must be performed at a specialist
tyre repair centre in accordance with the
procedures for the type of tread used.
8.4 ELECTRONIC CIRCUIT BOARD
The electronic circuit board is a component
fitted below the dashboard which
manages all machine safety devices.
The electronic board is fitted with a self-
rearming protection device that interrupts the
circuit in the event of a fault on the electrical
system; when this device is tripped, it stops the
engine and generates an acoustic signal that
can only be disabled by removing the key.
The circuit is re-armed automatically after
a few seconds; identify and eliminate the
cause or causes of the fault in order to
prevent subsequent interruptions.
IMPORTANT To avoid tripping the
electronic board protection device:
– do not invert the battery terminals;
– do not operate the machine without the
battery, as this would cause the battery
charge regulator to function irregularly;
– take care to avoid short circuits.
8.5 REPLACING A FUSE
The machine is fitted with fuses (fig. 49.A) with
different capacities and functions. Specifically:
– 10 A fuse = protects the electronic board
general and power circuits, when it
blows the machine stops running and the
dashboard light is extinguished (par. 5.16)
– 25 A fuse = protects the battery
recharge circuit. When it blows, the
battery gradually runs down and the
machine will have problems starting.
– 5 A fuse = protects the auxiliary 12 V
power supply socket for the attachments.
– 15 A fuse = protects the command motor
circuit, when it blows the electrical grass
catcher bag tipping system is disabled; in
this condition it is still possible to tip the
bag by using the manual lever (if fitted).
The fuse capacity is indicated on the fuse.
IMPORTANT A blown fuse must always
be replaced by one of the same type and
amperage and never with one of another rating.
If you are unable to understand why
it has blown contact Your Dealer.
8.6 REPLACING BULBS

1. Raise the bonnet and remove
the connector (fig. 52.A).
2. Detach the cotter pin (fig. 52.B) and
slide the bonnet off laterally.
3. Detach the LED light bulb cables (fig.
53.A), undo the screws (fig. 53.B)
and release the tabs (fig. 53.C).
4. Raise and release the upper part
