Electrical System - Grillo FX27 ZERO TURNING Manuel D'utilisation

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
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.
If the electrical problems still persist even after having changed the fuses, 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 detects if the foot rest platform is in the working position (fig. 20, ref. B).
Otherwise the cutting deck does not work.
- On the feed levers there are two micro switches that detect the position and the engagement of the
parking brake.
- Under the driving seat there is a micro switch that senses the driver's presence on the machine.
- The electrovalve that controls the machine's stabilizing mechanism on slopes (fig. 6, ref. C) is situated
behind the right hydrostatic transmission. Under normal working conditions the electrovalve is
illuminated by a red LED. When the machine's stabilizing device intervenes, the red LED goes out.
- On the electromagnetic clutch cable there is a diode that prevents returns of current.
- The control unit (fig. 3) signals when the main devices of the machine are engaged or disengaged.
Furthermore, it stores and indicates the machine's working hours.
AIR FILTER
Check and clean the air filter (fig. 4, ref. D) every 8 hours or more frequently if you work in dry and dusty
conditions. For the substitution and the exact maintenance intervals, please follow the instructions and
warnings given in the engine manual.
PETROL FILTER
The petrol filter (fig. 7, ref. B) prevents possible impurities in the petrol from getting in contact with engine
parts. Clean the petrol filter every 200 hours, and also wash the inside with clean petrol. For the cleaning
and the exact maintenance intervals, please follow the instructions and warnings in the engine manual.
CLEANING
Wash the cutting deck with a high-pressure water jet machine but do not direct the water jet to the
electrical components. Never clean the electric compartment with the high-pressure water jet machine,
use compressed air or a vacuum cleaner instead. Keep the hydrostatic transmissions area especially
clean in order to guarantee an efficient cooling. Always keep the aspiration grid on the engine and the air
filter clean.
TOWING HOOK
The towing hook is located in the rear part of the machine. You can tow compaction rollers and trailers
up to max. 120 kg weight on a 10% slope.
