SWITCHING TO PETROL DUE TO GAS LOW PRESSURE
When the switch reaches the reserve and the gas pressure falls under a pre-set value, the control unit
switches automatically to the petrol feeding. This occurs to avoid that the engine can operate with a too
weak mixture damaging in this way the catalytic converter. Before switching again to the gas feeding,
perform a fuel fi lling. The switching to petrol due to GAS LOW PRESSURE is signaled by the switch
with the switching-on of the YELLOW LED (petrol operation), the alternated switching-on of the RED
LED indicator and of the 4 GREEN LEDs and by the acoustic warning given by the internal buzzer.
To restore the switch to the normal operation, it is necessary to press the PUSH-BUTTON once; the
YELLOW LED remains switched-on to indicate that the car is petrol fed, and the buzzer stops buzzing.
