1)See the engine manual for the full list and frequency.2)At the first signs of wear, contact your dealer to replace the part.3)General lubrication of all joints should also be carried out whenever the machine is
to be left unused for a long period.  
The above table is there to help you maintain your machine’s safety and performance.
It shows the main maintenance and lubrication operations and their frequency. To the
right of each item, there is a box where you can write the date or after how many oper-
ating hours the work was carried out.
All checks, adjustments and replacements not described in
chapters 6.3 and 6.4 of this manual must be carried out by your Dealer or a
specialized Service Centre. Both have the necessary knowledge and tools to
ensure that the work is carried out correctly without affecting the safety of the
machine.

6.2.3 Rear axle
This is a sealed single unit that does not require maintenance. It is permanently lubri-
cated and its lubricant does not need changing or topping up.
6.2.4 Battery
The battery must be carefully main-
tained to ensure long life. The
machine battery must always be
charged:
–before using the machine for the
first time after purchase;
–before leaving the machine dis-
used for a long period;
–before starting up the machine
after a long period of disuse.
Carefully read and observe the bat-
tery recharging instructions in the
booklet provided with the battery.
Failure in following the instructions or
in charging the battery could perma-
nently damage the battery cells.
A flat battery 
must  be recharged as
soon as possible.
Recharging
must be done using a battery
charger at 
constant voltage. Other
recharging systems can irreversibly
damage the battery
The machine comes with a connector (1) for recharging; this is connected to the corre-
sponding connector for the special “CB01” maintenance battery-charger supplied
( if included) or available on request (☛8.5).
This connector must only be used for connection to the “CB01”
maintenance battery-charger. For its use:
–follow the instructions in the relevant user manual,
–follow the instructions in the battery manual.IMPORTANT

6.3 CHECKS AND ADJUSTMENTS
6.3.1 Cutting deck alignment
The cutting deck should be aligned properly set to ensure a good cut 
In order to make the adjustment, you may need to remove the lat-
eral guides which must be put back afterwards.
For achieving good results from
cutting, the front part should always be 5 - 6 mm
lower than the rear.
–Place the machine on flat ground and check the
tyre pressure;
–Put 26 mm blocks (1) under the front edge of the
deck and 32 mm blocks (2) under the rear edge,
then move the lifting lever to position «1»;
–unscrew the nuts (3 - 5 - 7) and locknuts (4 - 6 - 8)
so that the deck rests on the blocks;
–turn the nuts (9) (first remove
the central covering) so that
the rear left connecting rod
(10) starts moving at the
slightest movement of the
lifting lever, and then secure
it in place;
–screw down the rear left nut
(3) until the rear edge of the
cutting deck begins to rise;
–screw down the front nuts (5 - 7) until the front edge of the cutting deck begins to
rise evenly, both on the right and left side;
–screw down the three locknuts (4 - 6 - 8);
Shift the lifting lever to 2 or 3 different positions to check that the deck rises evenly
and that the front and rear edge are at the same height from the ground.
If the front edge tends to rise before or after the back edge, turn the nuts (11) on the
connecting rod (12). 
If you tighten the nuts, the front edge will rise first, while if you loosen them, the back
edge rises first.
When you have finished the adjustment, always check that all the nuts and locknuts
are tightened securely.
If the deck is still not correctly aligned, contact your Dealer.

6.4 DISMANTLING AND REPLACEMENT
6.4.1 Replacing wheels
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
eased off with a screwdriver.
If you have to replace one or
both rear wheels, make sure they have the same
diameter, and check that cutting deck is horizontal
to prevent an uneven cut.
Before remounting the wheel, apply grease to the axle. Put the
snap ring (1) and supporting washer (2) back in place.
6.4.2 Replacing and repairing the tyres
The tyres are “Tubeless” and so all punctures must be repaired by a tyre repairer fol-
lowing the procedures required for this kind of tyre.
6.4.3 Replacing the bulbs ( if present)
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.

6.4.4 Replacing a fuse
The machine is fitted with fuses (1)
with different capacities and func-
tions. Specifically:
–10 A fuse = protects the main
and power circuits of the elec-
tronic circuit board. When it
blows, the machine stops and
the dashboard light switches off.
–25 A fuse = protects the battery
charger circuit. When it blows,
the battery gradually runs out
and the machine will have prob-
lems starting.
The fuse capacity is indicated on
the fuse.
A blown fuse
must always be replaced by one
of the same type and ampere rat-
ing, and never with one of anoth-
er rating.
If problems persist, contact Your
Dealer.

6.5.2 Dismantling, replacing and remounting the blades
Always wear work
gloves when handling the blades.
Damaged or bent
blades must always be replaced;
never try to repair them! ALWAYS USE
ORIGINAL BLADES BEARING THE
SYMBOL   ! Make sure the blades
are correctly balanced. The blades are
different and rotate in different direc-
tions, so make sure you put them
back in the right place by referring to
the code stamped on the outside of
each blade. 
1. Dismantling
1a
= screw with right thread (loosen anti-
clockwise)
1b= screw with left thread (tighten clock-
wise)
2. Original spare parts
Only the following pairs of blades can be
used on this machine:
2b 
82004345/1 82004344/1 2a
2b 

82004354/0 82004353/0 2a
3. Remounting
Check that the concave part of the cushion
disc (3) presses against the blade.
Remount the shaft hubs (4), making sure
that the keys (5) are securely lodged in
place.
4. Tightening the screws
1a
= screw with right thread (tighten clock-
wise)
1b= screw with left thread (tighten anti-
clockwise)
Tighten with a 
torque wrenchcalibrated
to 40-45 Nm.
