SOLUTION
1. With the key on «ON», the light
stays off
The safety device of the electronic
circuit board has cut in due to:
– badly connected battery
– battery terminals crossed
– flat battery
– blown fuse
– wet circuit board
Turn the ignition key to «STOP»
and look for the cause of the
problem:
– check connections (see 3.4)
– check connections (see 3.4)
– recharge the battery (see 6.2.3)
– replace the fuse (10 A)
(see 6.3.5)
– dry using luke warm air
2. With the ignition key turned to
«START» the light flashes and
the starter motor does not run
– starting conditions have not
been met
– check that all starting conditions
are met (see 5.2.a)
The wheels are held by a snap ring (1) which
can be removed with a screwdriver.
NOTE
If you have to replace one or both rear
wheels, make sure that any differences in their
external diameter does not exceed 8-10 mm; on
the contrary, you must adjust the cutting-means
assembly alignment to prevent uneven mowing.
IMPORTANT
Before remounting the wheel,
apply grease to the axle. Put the snap ring (1)
and shoulder washer (2) back in place.
6.3.3 Repairing or replacing tyres
The tyres are “Tubeless” and must be replaced
or repaired if punctured by a specialized tyre
repairer following the procedures required for
this kind of tyre.
6.3.4
Replacing bulbs ( if fitted)
• Type “I” bulbs (incandescent) (Fig. 6.5)
The bulbs (18W) have a bayonet fitting and are
installed in the bulb holder which can be taken
out by turning it anti-clockwise with pliers.
• Type “II” bulbs (LED) Fig. 6.6)
Unscrew the ring-nut (1) and remove the con

6.3.5 Replacing a fuse (Fig. 6.7)
The machine is fitted with fuses (1) with different
capacities and functions. Specifically:
– 10 A fuse = protects the main and power cir
-
cuits of the electronic circuit board. When it
blows, the machine stops and the dashboard
light switches off.
– 25 A fuse = protects the battery recharge cir
-
cuit. When it blows, the battery gradually runs
down and the machine will have problems
starting.
The fuse capacity is indicated on the fuse.
IMPORTANT
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 are unable to understand why it has
blown, contact Your Dealer.
