Electrical System - Grillo FD13.09 Notice D'utilisation

PARKING AND EMERGENCY BRAKE ADJUSTMENT
The brakes adjusting devices are under the platform (fig. 27, ref. A). The drum brakes are on the front wheels, pay attention that
the cable does not hit the wheel (fig. 28).

ELECTRICAL SYSTEM

The electrical system is protected by fuses which, if blown, cause the whole electrical system to cut out. These are located under
the bodywork, opening the loading accelerator check gate (fig. 29). There are two main fuses (fig. 30): the general one with 50 A/
h, and the one that feeds the ignition key with 40 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. Some relays are inside the box (fig. 31).
FUNCTIONING OF THE MAIN ELECTRICAL DEVICES
-
A safety sensor detects if the grass catcher is in working position (fig. 32), otherwise the cutting deck does not work.
-
A sensor is fitted on the radiator (fig. 15, ref. B). It detects the cooling liquid temperature. When the cooling liquid
temperature goes beyond 88°C, the sensor sends a signal to the control unit (fig. 31) 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. 1 n° 25). There are four radiator fan inversion relays (fig. 29).
-
On the thermostatic valve casing two sensors are fitted: the left one is connected to the instrument that indicates the liquid
temperature, the right one sends the alarm and engine turn-off signal if the temperature goes beyond 110°C (fig. 33).
-
On the forward pedal a microswitch is fitted which detects the stop position for the start (fig. 34, ref. A).
-
On the parking brake blocking pedal there is a sensor (fig. 34, ref. B) that detects when the brake is engaged and that allows
the engine to keep running even if the operator has left the driving seat.
-
On the reverse gear pedal tie rod there is a microswitch that activates the reverse gear warning buzzer (fig. 34, ref. C).
-
The differential lock electric valve (fig. 6, ref. A) is under the accelerator: when it starts, a red led lights up.
-
The full grass catcher microswitch 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. 10, ref. A).
AIR FILTER
Check and clean the air filter (fig. 9) and the pre-filter (fig. 13) every 8 hours. The air filter is equipped with a depression sensor
that signals on the dashboard that the filter is obstructed. For the substitution and the exact maintenance intervals please follow
the instructions and warnings in the engine manual.
DIESEL FILTER and DIESEL DECANTING DEVICE
Change the diesel filter cartridge (fig. 14, ref. A) every 250 hours. For the substitution and the exact maintenance intervals
please follow the instructions and advices in the engine manual. The decanting device (fig. 5, ref. C) makes it possible for liquid
impurities in the diesel or water to deposit on the ground so that they do not get in contact with engine parts. Clean the decanting
device every 250 hours, and also wash the inside with clean diesel. Check the decanting device at every use. For the cleaning
and the exact maintenance intervals please follow the instructions and advice in the engine manual. Attention! When you fill up
the diesel tank, always use a very fine filter.
CLEANING
Clean the deck, the entry ducts, the loading accelerator and the grass catcher. Do not wash the engine compartment with water
under pressure, use compressed air or a vacuum cleaner.
TOW BAR
The tow hitch is located at the rear of the mower. The max. towing weight is 250 kg on flat grounds.
TOWING THE MACHINE WITH SWITCHED OFF ENGINE
Attention! To move the machine with the engine switched off undo by two turns the screw on the hydrostatic pump (fig. 35); pay
attention because doing so the efficiency of the self-braking device is cancelled. Tow the machine at very low speed and only
on small distances, maximum 100 metres, to avoid seizing the hydraulic pump or engine.
STORAGE AND LACK OF USE FOR LONG PERIODS
Store the machine in a dry environment, sheltered from bad weather conditions and, if possible, covered up. Clean the machine
from grass residues. If the machine is to be out of use for more than 30 days, detach the red cable from the battery and follow
the engine manual instructions. Remember to lubricate all the joints. Regularly check that the battery voltage does not go under
12,5 Volts. If it is below, recharge the battery.
