Electrical System - Grillo FD 2200 TS Bedienungsanleitung

MECHANICAL PARKING BRAKE
Always use the parking brake even if when the engine is off the machine brakes automatically. The brake is
engaged by pulling the handle upwards. To disengage it, push the button and lower the handle. The engine keeps
on running if the operator leaves the driving seat, provided the parking brake is engaged and both the blades and
the turbine are disengaged. Make sure the parking brake cable (fig. 27, A) is steadily adjusted.
PARKING BRAKE ADJUSTMENT AND EMERGENCY BRAKE PEDAL
The brake pedal has to make a 3 mm stroke before activating the hydraulic brake pump. To this purpose, the brake
pedal has an eylet instead of a hole to ensure the mechanical connection with the pump (fig. 27, B).
IF THE MACHINE DOES HOLD THE STOP POSITION
If the machine does not stop or drives backwards, although the pedals are in the stop position, adjust the screws
that regulate the mechanical stroke of both pedals (fig. 28). This operation must be carried out by an authorised
dealer.

ELECTRICAL SYSTEM

The electrical system is protected by fuses which, if blown out, cause the whole electrical system to cut out.
1) On the left side over the battery there are two fuses, one of 50 A/h and one of 15 A/h (fig. 29, B). The 50 A/h fuse
protects the whole electrical system, while the 15 A/h fuse protects the electronic control unit.
2) The two fuse boxes are located under the seat (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. To reset the electronic control unit, remove the 15 A/h fuse.
Some electrical components are positioned in the box next to the seat (fig. 31). The three relays and the electronic
control unit (fig. 30, B) can be accessed by opening the cover under the seat.
A safety micro-switch detects if the grass catcher is in working position (fig. 24, B), otherwise both the turbine and
the cutting deck will not engage.
If the electrical problems still persist even after having carried out the procedures outlined above, contact an
authorized dealer. Never attempt to carry out complex repairs without having the necessary means and technical
knowledge.
HOW THE MAIN ELECTRICAL SYSTEM DEVICES WORK

A safety micro-switch detects if both the grass catcher and the mower deck are in working position,
otherwise the cutting deck and the turbine do not work. When the mower deck is raised into transfer
position, blades disengage for safety reasons (fig. 32, A).

A micro-switch is located on the radiator to detect the temperature of the cooling liquid. When its temperature
goes over 92°C, the micro-switch activates the electronic control unit which starts the automatic cleaning cycle,
reversing the radiator fan rotating sense for some seconds. It is possible to carry out the cleaning cycle also
manually by pushing button on the dashboard (fig. 2 no. 4). Do not frequently activate the manual cleaning
cycle, because this could determine an increase in the engine's temperature.

On the thermostatic valve casing a temperature thermal contact is fitted (fig.2, no. 9) which is connected to the
dashboard and indicates the liquid temperature. This sensor then sends an alarm and cut the engine off if
temperature goes over 107°C.

On both the forward and reverse pedal there are two micro-switches detecting the machine's stop position to
give consent to the start (fig. 47). The micro-switch on the reverse pedal activates the warning buzzer too.

On the parking brake lever there is a sensor (fig. 40, B) that detects when the brake is engaged and allows the
engine to keep running even if the operator has left the driving seat.

The differential lock electrovalve is located behind the radiator (fig. 19): when it is on, a red LED lights up.

The full grass catcher micro-switch is fitted on the mobile deflector inside the grass catcher and disengages the
blades when the grass catcher is full (fig. 14, A).
DASHBOARD
When the lawnmower is switched on, the Grillo LOGO will be displayed. To show the different functions of the
dashboard push the button (fig. 2,, n. 8). The display will show:
