If mowing is uneven, check the tyre pressure.
If this is not sufficient to achieve an even cut,
please contact your Dealer to adjust the align-
ment of the cutting-means assembly.
6.4.2 Replacing the wheels (Fig. 6.6)
Stop the machine on flat ground 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 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.
6.4.3 Repairing or replacing tyres
All puncture repairs or replacements will have to
be carried out by a tyre repair expert in accord-
ance with the methods for the kind of tyre used.
6.4.4 Replacing a fuse (Fig. 6.7)
The machine is fitted with fuses (1) with different
capacities and functions. Specifically:
– 1 0 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.
– 2 5 A fuse = protects the battery recharge cir-
cuit. When it blows, the battery gradually runs
down and the machine will have problems
starting.
With Honda engine
– 1 0 A fuse = protects the main and pow-
er circuits of the electronic circuit board.
When it blows, the machine stops and the
dashboard light switches off.
– 2 5 A fuse = protects the battery recharge
circuit. When it blows, the battery gradu-
ally runs out and the machine will have
problems starting.
– T 6.3 A (delayed) fuse (2) = protects the
main and power circuits of the electronic
circuit board. When it blows, the machine
stops and the dashboard light switches off.
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.
6.4.5 Replacing bulb (if fitted) (Fig. 6.8)
The bulb (18W) has a bayonet fitting and is in-
