riod.
6.3.1 Engine
Follow the instructions in the engine booklet.
Drain the engine oil by unscrewing the oil fill plug (1) and
using the syringe supplied.
Fit the pipe (2) onto the syringe (3) and insert it right into the
hole. Drain all the engine oil, repeating if necessary until
there is no oil left in the engine.

							6.3.2 Rear axle
These are permanently lubricated with grease that does not need changing.
6.3.3 Battery
To ensure long life to the battery it is essential to
keep it carefully maintained.
The machine battery must always be charged:
– before using the machine for the first time afterpurchase;
– before leaving the machine for a prolonged period of disuse;
– before starting up the machine after a pro- longed period of disuse.
– Carefully read and comply with the procedure for recharging described in the booklet coming
with the battery. If the procedure is not fol-
lowed or the battery is not charged, irreparable damage could be caused to the ele-
ments inside the battery.
– 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 has a connector (1) for recharging, to be connected to the corresponding
connector of the special “CB01” maintenance battery-charger supplied   ( if included)
or available on request (chapter 8).
This connector must only be used for connection to the “CB01”
maintenance battery-charger. For its use:
– follow the instructions given in the relative instruction booklet,
– follow the instructions given in the battery booklet.
6.4 CHECKS AND ADJUSTMENTS
6.4.1 Cutting deck adjustment
The cutting deck should be properly adjusted to obtain a good cut. Height adjust-
ments to the cutting deck are made through three linkages.
Such adjustments are to be made on a flat sur-
face after having ensured that the tyre pressures
are correct. For achieving good results
from cutting, the front part should always be 2 -
4 mm lower than the rear.

							To adjust the cutting deck so that it is parallel
with the ground:
– put one 26 mm block (1) under the edge of thedeck and one 32 mm block (2) under the rear
edge, then put the lifting lever into the notch at
position «1»;
– loosen the nuts (3 - 5 - 7) and the locknuts (4 - 6 - 8) so that the deck is resting firmly on the
blocks;
– turn the nut (3) until the right-hand rear part of the deck starts to rise, and then tighten the rel-
ative locknut (4);
– screw down the nut (5) on the rod until the right-hand front part of the deck begins to rise,
and then tighten the relative locknut (6);
– screw the nut (7) on the front left support until the deck in that area begins to rise, and then
tighten the nut (8).
If you are unable to get the cutting deck parallel,
consult a Licensed Service Centre.
6.5 DISMANTLING AND REPLACEMENT
6.5.1 Changing wheels
Stop the machine on a flat surface and put
blocks 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 taken off with a screwdriver.
The rear wheels are directly coupled to the axle
shafts and fastened by a key that forms part of
the wheels hub.
Before re-fitting a wheel, smear some grease on the axle and carefully re-fit the snap
ring and washer (2).
Should you substitute one or both rear wheels, ensure that they
are of the same diameter, and check that cutting deck is horizontal to prevent an
uneven cut.

							6.5.2 Changing and repairing tyres
Tyres are of the «Tubeless» type and therefore all puncture repairs will have to be car-
ried out by a tyre-repair expert in accordance with the methods for this kind of tyres.
6.5.3 Replacing a fuse
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 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 problems starting.
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 one of a different rating.
If you cannot find the cause of the protection devices activation, consult a Licensed
Service Centre.
6.5.4 Changing belts
The motion from the engine to the rear axle and from the motor to the blade is
obtained by two “V” belts, whose duration largely depends on how the machine is
used.
Replacing belts is quite complicated because of dismantling and adjustme\
nts and
must only be carried out by a Licensed Service Centre. Belts must always be replaced as soon as they are seen to be
worn! ALWAYS USE MANUFACTURER’S GENUINE SPARE BELTS!

							6.6.2 Dismantling, replacing and remounting the bladeAlways wear work gloves when handling the blade.
Damaged or bent
blade must always be replaced;
never try to repair it! ALWAYS USE
ORIGINAL BLADES BEARING THE
SYMBOL   ! Make sure the blade is
correctly balanced.
1. Dismantling
To remove a blade, hold it firmly and
undo the central bolt (1) in the direction
indicated by the arrow.
3. Balance
To ensure that it works properly without
unusual vibrations any imbalance
between the two parts of the blade must
be below one gram.
3. Remounting
Check that the concave part of the
cushion disc (3) presses against the
blade. Remount the shaft hub (4), making
sure that the key (5) is securely lodged in
place.
4. Tightening the screw
With a torque wrench calibrated to
40-45 Nm tighten the fixing screw (1).

							ACCESSORIES ON REQUEST38EN
1. FRONT COUNTERWEIGHTS
These improve stability at the front of the machine,
particularly when being used on ground which is
mostly sloping. 
2. STONE-GUARD KIT
For use in place of the grass-catcher when the
cuttings are not to be collected.
3. “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.
4. KIT FOR “MULCHING”
It finely chops the grass cuttings and leaves them
on the lawn, instead of collecting them in the
grass-catcher
