CAUTION: If the problems continue after having carried out the operations described in this manual,
contact an Authorized Service Centre. Never attempt to make difficult reparations without the
necessary means and technical knowledge.
IMPACT WITH A STONE OR SOME OTHER FOREIGN OBJECT
1) Stop the machine.
2) Disengage the PTO.
3) Lift the cutting deck up.
4) Turn off the engine.
5) Pull the parking brake.
6) Check the blade fixing screws and the deck state.
7) Please check that the foreign body has not got into the turbine or the pipe.

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.
