MECHANICAL PARKING BRAKE
Always use the parking brake even if when the engine is off the machine brakes automatically.
The brake applies by pulling the handle upwards; to release it push the button and lower the handle.
The engine keeps on even when the operator leaves the driving seat, provided the parking brake is applied and the
blades and the turbine are disengaged.
Make sure the parking brake cable (fig. 27, ref. A) is steadily adjusted.
PARKING BRAKE ADJUSTMENT AND EMERGENCY BRAKE PEDAL
The brake pedal has to make a 3 mm travel before activating the hydraulic brake pump. To this purpose, the brake
pedal has a slot instead of a hole for the mechanical connection with the pump (fig. 27, ref. B).
IF THE MACHINE DOES NOT KEEP THE STOP
If the machine does not stop or drives backwards although the pedals are in the stop position, act on the pump
(fig. 28). This operation has to be carried out by an Authorised Service Centre.
ELECTRICAL SYSTEM
The electrical system is protected by fuses which, if blown out, cause the whole electrical system to cut out. These
are located:
1) On the left side, over the battery there is the general fuse with 70 A/h (fig. 29).
2) The operation fuse boxes are on the left side of the seat on the fairing (fig. 30).
Once the fault has been located and repaired, replace the blown fuse with one of the same rating. Never
replace a fuse with another of a different rating.
All relays are inside the box (fig. 31).
A safety micro switch controls that the grass catcher is in working position (fig. 32, ref. C), otherwise the turbine and
the cutting deck will not engage.
If the electrical problems still persist even after having carried out the described interventions, contact the
Authorised Service Centre. Never attempt to carry out complex repairs without having the necessary means and
technical knowledge available.
HOW THE MAIN ELECTRICAL SYSTEM DEVICES WORK
-
A safety micro switch controls that the grass catcher is in working position (fig. 32, ref. C), otherwise the cutting
deck and the turbine do not work.
-
A micro switch is fitted on the radiator (fig. 19, ref. B). It measures the coolant temperature. When the coolant
temperature goes beyond 92°C, the micro switch sends a signal to the control unit which starts the automatic
cleaning cycle, inverting for some seconds the radiator fan rotating sense. It is possible to carry out the
cleaning cycle also by hand acting on the respective button on the control panel (fig. 2 no. 5).
-
On the thermostatic valve casing a temperature thermal contact is fitted, the latter is connected to the
instrument that indicates the liquid temperature and which sends the alarm and the engine cut-off signal if the
temperature goes beyond 107°C (fig. 16, ref. B).
On the feed pedal a micro switch is fitted which senses the stop position to give consent to the start (fig. 47).
-
-
On the parking brake lever there is a sensor (fig. 40, ref. B) that senses when the brake is engaged and that
allows that the engine keeps running even if the operator has left the driving seat.
-
On the reverse gear pedal tie rod there is a micro switch that activates the reverse gear warning buzzer (fig. 48).
-
The differential locking electric valve (fig. 46, ref. A) is behind the radiator: when it starts, a red led lights up.
-
The full grass catcher micro switch is fitted on the mobile deflector inside the grass catcher and sends the
signal to disengage the blades when the grass catcher is full (fig. 14, ref. A).
RADIATOR FAN ELECTROVALVE
The electrovalve of the radiator fan is on the machine left hand side, near the battery (fig. 21, ref. B) and it controls
the fan inversion to carry out the radiator cleaning cycle. The cycle can be started automatically or manually acting
on the button in the dashboard. When the engine is started, a red led goes on in one of the two electrovalve coils,
whereas when the cleaning cycle is being carried out, the led light comes on in the second coil.
TURBINE ACTIVATING ELECTROVALVE
The turbine activating electrovalve is on the machine left hand side of the, near the battery (fig. 21, ref. C). By
pressing the button on the dashboard the electrovalve activates the turbine. The electrovalve can be unlocked by
acting on the central pin in the middle of the coil shaft. When the electrovalve receives electricity, a red led comes on.
CLUTCH ACTIVATING ELECTROVALVE
The clutch engagement electrovalve (fig. 49) is under the footrest platform: to inspect and control it, open the flap
under the seat. The calibration is 7 bar. It is important not to change it to avoid damaging the clutches seals.
CLEANING
Clean the deck, the entry ducts, the loading turbine and the grass catcher. Do not wash the engine compartment
