NGINE
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 nec-
essary until there is no oil left in the engine.

							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 after purchase;
– before leaving the machine for a prolonged period of disuse;
– before starting up the machine after a prolonged 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 followed or the battery
is not charged, irreparable damage could be caused to the elements inside the
battery.
– A flat battery must be recharged as soon as possible.
Recharging must be done using a battery charger at con-
stant voltage.Other recharging systems can irreversibly damage the battery.
The machine has a connector (1) for recharg-
ing, 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” main-
tenance battery-charger. For its use:
– follow the instructions given in the relative
instruction booklet,
– follow the instructions given in the battery booklet.
R
EPLACING A FUSE
The machine is fitted with fuses (1) with differ-
ent 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.
C
HANGING 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 screwdriv-
er.
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 pre-
vent an uneven cut.
C
HANGING AND REPAIRING TYRES
Tyres are of the «Tubeless» type and therefore all puncture repairs will have to be
carried out by a tyre-repair expert in accordance with the methods for this kind
of tyres.

							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 adjustments
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!
C
UTTING DECK ADJUSTMENT
The cutting deck should be properly adjusted
to obtain a good cut. Height adjustments to
the cutting deck are made through three link-
ages.
Such adjustments are to be made on a flat
surface 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
the deck 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 relative 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.
B
RAKE ADJUSTMENT
The adjustment will need to be made while the
parking brake is engaged.
For mechanical drive models:
Loosen the nut (1) which holds on the bracket
(2) and turn the nut (3) until the length of the
spring (4) is 46 - 48 mm inside the washers. 
When the adjustment has been made, tighten
the nut (1). 
For  hydrostatic drive models:
Turn the nut (5) until the length of the spring
(6) is 45 - 47 mm inside the washers.
Do not screw to below
these values to avoid overloading the brake
unit.
A
DJUSTING DRIVE ENGAGEMENT
For mechanical drive models:
If you should notice that forward drive
power has dropped, you can adjust the
regulating screw (1) which is accessible
through the hatchway beneath the seat.
Undoing the screw and then lengthening
the spring (2) will increase the drive ability.
The best length for the spring is 86 mm measured from the outer ends of the
spring. Once the adjustment has been made, tighten the locknuts (3). Exces-
sive spring tension may cause too sudden engagement of the clutch, resulting
in the machine tipping up.➤

							ADJUSTMENT TO BLADE ENGAGEMENT AND BRAKE
If there seem to be problems in engaging the
blade or the time for stopping after disen-
gagement is over 5 seconds, adjust the
spring tension (1). 
To make this adjustment, loosen the nuts (2)
and screw or unscrew them on the control
rod (3) in order to obtain a distance of 77-79
mm between the bracket (4) and the inside
of the washer (5), with the blade engaged and the cutting height adjustment
lever at position “1”. When the adjustment has been made, screw the nuts (2)
back on.
For  hydrostatic drive models:
A
DJUSTING THE SPEED CHANGE LEVER
The speed change lever has a clutch device which
keeps it in the position selected during forward
movement and which returns the lever to neutral
when brake is operated.
If the lever does not stay in position during working
and has difficulty in returning to neutral, the adjuster
nut (1) will need to be registered to restore normal
functioning.
S
HARPENING THE BLADE
Check that the blade is sharpened properly and firmly fixed to the bracket.
– A badly sharpened blade pulls at the grass and causes the lawn to turn yellow.
– A loose blade causes unusual vibrations and can be dangerous.
All operations on the blade (dismantling, sharpening,
balancing, remounting and/or replacing) require a certain familiarity and
special tools. For safety reasons, go to a specialized centre if you do not
have the right tools or experience.
!WARNING!

							To remove the blade, hold it firmly wearing
strong gloves and undo the central screw
(1).
Sharpen the two cutting edges using a
medium grade grinding wheel and check
the balance by holding the blade up with a
round 18 mm diameter bar inserted in the
central hole.
To ensure that it works properly without
unusual vibrations any imbalance
between the two parts of the blade must
be below one gram.
This can be easily ascertained by putting
a one gram weight on the lightest end of
the blade. If it tends to go below the bal-
anced position it means that the balance
is correct, while if it stays up then the
other end will have to be made lighter.
A damaged or bent
blade must always be replaced;
never try to repair it! ALWAYS USE
MANUFACTURERS GENUINE
SPARE BLADES  !
When re-fitting the
blade, always follow the indicated
sequence, making sure that the
blade’s wings are facing towards the
interior of the cutting deck and that
the concave part of the cup spring
(1) is pressing against the blade.
Tighten the fixing screw (2) using a
torque wrench set to 45-50 Nm. If the
shaft hub (3) came off when disman-
tling the blade, make sure that the
key (4) is firmly in its right position.
