6.3 CHECKS AND ADJUSTMENTS
Summary of the main situations where work may be required
6.3.1 D
ISMANTLING, SHARPENING AND BALANCING BLADES
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 blades (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.
Wear strong gloves when handling the blades.
To remove a blade, hold it firmly and undo the central bolt (1)in the direction
indicated by the arrow for each blade, noting that one of the fixing bolts has

							a right-hand thread and the other one has a left-hand thread.
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 Ø bar inserted in the
central hole.
Damaged or bent blades must always be
replaced; never try to repair
them! ALWAYS USE MANUFAC-

The blades dif-
fer, are at 90° to one another, and
are contra-rotating. When
installing them, make sure that
they are correctly positioned by
refering to the code number
marked on the outside of each
one.
When re-fitting the blades, always follow the indicated
sequence, making sure that the blades wings are facing towards the
interior of the cutting deck and that the cupped side of the cup washer (1)
is pressing against the blade. Tighten the fixing screws (2) using a torque
wrench set to 45-50 Nm. If one or both shaft hubs (3) come off when dis-
mantling the blades, make sure the keys (4) are securely lodged in place.

							For achieving good results
from cutting, the front part should always be 5 -
6 mm lower than the rear.
– Put the machine onto a flat surface and check
the tyre pressures;
– put 26 mm blocks (1) under the front edge of
the deck and 32 mm blocks (2) under the rear
edge, and thenput the lifting lever into position
«1»;
– loosen the nuts (3), the screws (5) and the lock-
nuts (4 – 6) on both the right and left side, so
that the deck is resting firmly on the blocks;
–  push the two connecting rods (7) to the back
and screw down the two nuts (3) on each rod
until the front part of the deck just begins to
rise both at the right and the left, and then
tighten the relevant locknuts (4);
–  turn both the rear screws (5) until the rear of the
deck begins to rise both at the right and the
left, and then tighten the relevant locknuts (6).
If you are unable to get the cutting deck adjusted properly, consult a Licensed
Service Centre.
6.3.3 A
DJUSTMENT TO THE ENGAGEMENT AND BRAKE OF THE BLADES
For models with lever operated engage-
ment
When the lever to disengage the blades is
operated, this also brings the blade brake
into operation for stopping the blades within
few seconds.
A badly functioning blade brake is usually
due to wear in the brake lining (2) and this will
need to be changed by a Licensed Service Centre. 
A stretched cable and changes in the length of the belt can impair the blades’
engagement or rotation. 
To compensate this, turn the adjusting nut (1) till the correct spring length is
achieved (measured from the outer ends of the spring with the blades
engaged).➤

							For models with electromagnetic clutch
If there is an unusual rotation due to
the belt; turn the adjusting nut (1) till
the correct spring length is achieved
(measured from the outer ends of the
spring).
If the electromagnetic clutch does not
manage to drive the belt or the blades
do not stop within few seconds, imme-
diately contact a Licensed Service
Centre.
6.3.4 B
RAKE ADJUSTMENT
If the braking distance becomes longer than
the amount indicated (☛5.3.6), the brake
spring will need to be adjusted.
The adjustment will need to be made while
the parking brake is engaged. Access for
making this adjustment is by taking off the
inspection hatch beneath the seat.
Loosen the nut (1) which holds on the brack-
et (2) and turn the nut (3) until the length of
the spring is:
A= 47.5 - 49.5  mm (For mechanical
drive models)
B= 45 - 47  mm (For hydrostatic drive
models)
measured inside the washers. When the
adjustment has been made, tighten the nut
(1). 
Do not screw below these values to avoid overloading the
brake unit.
If the brake still does not work properly even after this

6.3.5 A
DJUSTING THE TENSION OF THE DRIVE BELT
If you should notice that forward drive power
has dropped, it will be necessary to adjust
the tension of the spring of the stretcher to
return to former conditions.
Access for making this adjustment is by tak-
ing off the inspection hatch beneath the seat.
Loosen the locking nuts (2) and tighten or
loosen the screw (1) as much as necessary
for a length “A” of the spring (3) of:
A= 114 - 116  mm ( For mechanical drive models)
A= 109 - 111  mm ( For hydrostatic drive models)
measured to the outside of the end of the spring. When the adjustment has been
made, tighten the nuts (2).
When replacing the belt, take great care when using for the
first few times as engagement may be sudden until the belt is sufficiently run in.
6.3.6 A
DJUSTMENT OF THE SPRING OF THE PAWL FOR HOOKING THE GRASS-CATCHER
If the grass-catcher tends to jump about and to
open up when going over rough ground, or if it has
difficulty in hooking back on after being emptied,
the tension of the spring will need to be adjust-
ed(1).
Change the hooking point by using one of the
holes (2) until the required result is achieved.

6.4.1 R
EPLACING WHEELS
Stop the machine on a flat surface 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.
The rear wheels are directly coupled to the differen-
tial axle shaft and fastened by a key that forms part
of the wheels hub.
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.
Before re-fitting a wheel, smear some waterproof grease on
the axle and carefully re-fit the snap ring (1) and washer (2).
6.4.2 R
EPLACING AND REPAIRING TYRES
The 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 tyre.
6.4.3 R
EPLACING BULBS
The bulbs (18W) have a bayonet fitting
and are installed in the bulb holder which
can be taken out by turning it anti-clock-
wise, using pliers.

							6.4.4 REPLACING A FUSE
The machine is fitted with fuses (1) with different capacities and functions.
Specifically:
– 10 A fuse = protects the main and
power circuits of the electronic board.
When it blows, the machine stops and
the dashboard switches off.
– 25 A fuse  = protects the battery charg-
er circuit. When it blows, the battery
light comes on to indicate that the bat-
tery is going to run 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 with one of another rating.
If you cannot find out why the fuse has blown, consult a Licensed Service Cen-
tre.
6.4.5 R
EPLACING BELTS
Replacing belts is quite a complicated process of dismantling and subsequent
adjustment and must only be carried out by a Licensed Service Centre.
Replace the belts as soon as they show obvious signs of
wear! ALWAYS USE GENUINE REPLACEMENT BELTS!
