Change-over from PETROL to GAS
If the vehicle’s ignition is on, the GAS electrovalve is opened for 3 seconds
approxmately. This change-over switch is fitted with a safety device that
closes the GAS electrovalve if the engine stops accidentally. While the GAS
electrovalve is open, the two-colour led is on in a GREEN color.
Position the switch on PETROL. This will open the PETROL electrovalve
while the GAS electrovalve remains open for 4 seconds to allow the
carburetor chamber to be filled in. During these seconds, the two-colour led
blinks in RED and there is a GREEN light on.
Position the switch on the NEUTRAL position (central position of switch), so
that the fuel remaining in the carburetor is consumed. The two-colour led
indicates this condition blinking with a RED light, then position the switch on
GAS.
