the necessary means and technical knowledge.
IMPACT WITH A STONE OR SOME OTHER FOREIGN OBJECT
1) Stop the machine.
2) Turn off the engine and apply the parking brake.
3) Tilt the cutting device.
4) Check the blade fixing screws and the deck condition.

MECHANICAL PARKING BRAKE

The parking brake device wire (fig. 5, ref. B) has to be adjusted. The brake is activated by opening the
steering levers outwards (fig. 1, no. 1). To release the brake just put the steering levers back into the
working position.
Always apply the parking brake when you leave the machine.
The engine keeps running even if the driver leaves the seat, if the parking brake is engaged. If the
parking brake should be hard to apply, you can intervene on the activating wire adjusting the relevant
adjusting screws (fig. 5, ref. B).
ELECTRICAL SYSTEM
The electrical system is protected by fuses which, if blown out, cause the whole electrical system to cut out.
These are located under the driver's seat by tilting the seat for the machine inspection. There are two main
fuses (fig. 17, ref. B and C): the general fuse with 25 A/h and the one that feeds the services with 15 A/h.
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.
