3.1 CRITERIA FOR MAINTENANCE
The Instruction Handbook has a number of operations to be carried out by the Customer for a minimum of
basic maintenance, and other operations not always within his capacity.
For this reason the Service Centre should undertake to keep the machine in perfect working order in two
ways:
a)Tuning the machine whenever possible.
b)Proposing a regular maintenance programme to the Customer to be carried out at prearranged intervals
(for example, at the end of the summer or...

BLADE ENGAGEMENT ADJUSTMENT

WORKSHOP MANUAL

1997to  ••••
4.1 BLADE ENGAGEMENT ADJUSTMENT
The blades are run from the engine using a “V”
belt and are engaged by a stretcher worked from
the lever.
After a certain amount of use the belt and the
cable can become longer which can result in mal-
functioning, i.e.:
–belt slipping = belt or cable stretched
–difficulty in disengaging, with a stiff lever and
the blades continuing to run = belt...

4.2 BLADES BRAKE ADJUSTMENT
Disengaging the blades causes a double brake to
come into action. This is to stop the blades turn-
ing within five seconds.
Longer braking times do not comply with safety
regulations, but adjusting the brake so that it
stops quicker than this can cause the belt to slip
on the shoes resulting in overheating with the typ-
ical smell of burnt rubber.
Take off the right-hand protective guard (1)by
unscrewing the nut 
(2)and loosening the two
screws 
(3). Take off the left-hand...

4.3 BRAKE ADJUSTMENT
Reduced braking power is corrected by adjusting
the spring on the brake rod.
➤In mechanical drive models:

Remove the fuel tank [see 5.4].
➤In the hydrostatic drive models: 
Use a socket spanner to make the adjustment
through the hole 
(1) on the rear plate.
The adjustment is to be made with the parking
brake engaged and consists of altering the length of
the spring 
(2)to the best measurement. The braking
capacity is increased by screwing the nut down on...

brake pads or discs are so worn that they need replacing [see 6.11].
When connecting the rod 
(3)be sure to use the uppermost hole in the lever (7)and then check the length of
the spring again 
(2).
➤In the hydrostatic drive models: 
If braking is still poor or unsteady even after making the adjustment, you cannot make any further adjust-
ments from the outside. Therefore you need to dismantle the whole rear axle of the machine [see 5.5] and
contact one of the manufacturer’s Service Centres.

DRIVE BELT ADJUSTMENT

WORKSHOP MANUAL

4.4 DRIVE BELT ADJUSTMENT
If it seems that the forward drive is not working
properly after a long period of use or after replac-
ing the belt, this may be caused by a change in the
length of the belt.
–A loose belt reduces output from the transmis-
sion and limits forward movement power;
–a belt which is too tight increases noise and
results in jerky movements or tipping up when
engaging the...

4.5 DRIVE PEDAL ADJUSTMENT - (➤Hydro-
static drive models) 
This operation should be carried out every time
the rear axle, the pedal or the control rod is
removed in order to get the correct travel for the
pedal and to enable reaching the envisaged
speeds both forwards and in reverse.
A) Adjusting the pedal in the “neutral” position
The pedal (1) is in the ideal position when the lever
(2)of the hydrostatic unit is in “neutral” and the
lower rubber edge
(3)on the reverse side is 24 – 26
mm from the...

4.6 ALIGNING THE CUTTING DECK
The cutting deck is lowered by a level controlled
cable, and is moved by two trace rods at the front
and back.
In order to get a good cut it is essential that the
cutting deck is parallel with the ground crosswise,
and slightly lower at the front.
Three adjustments can be made on the jointed
system of the cutting deck:
a)a combined adjustment to the parallel and the
minimum height front and back
b)an adjustment to just the parallel across the
cutting deck
c)adjusting the...

C) Adjusting the regularity of raising and lowering
When the adjustment as at point “A” has been made, put the control lever in 2 or 3 different positions and
check that the deck rises evenly and that at each position it constantly maintains the difference in height from
the ground between the front and back edges.
If the front part tends to rise faster or slower it can be adjusted by turning the nuts 
(10)on the link rod (11).
Turning the nuts clockwise will lift the front part and make it rise...

4.7 STEERING ALLOWANCE ADJUSTMENT
The steering allowance should never be excessive
if driving is not to be impaired.
Check that the movement is not caused by loose
linkage nuts and tighten all the nuts of the tie-rods
and ball joints.
If the movement is due to the ring gear / pinion cou-
pling, it will be necessary to adjust the arrangement
of the set of blocks between the ring gear and the
frame.

 Remove the fuel tank [see 5.4].
To facilitate access to the parts concerned, it is best
to loosen the...
