progressively under full load acceleration.
Maintenance operations:

Before performing any work on the vehicle, drain the LPG circuit.
Only personnel who have undergone special LPG training can work with gas unions where gas is circulating and
which run from the expansion valve via the fuel tank.
Equally, only these persons are permitted to perform servicing and repair operations on LPG vehicles.
Workshops can only carry out work on the fuel tank if they have a degassing burner. If the tank cannot be
degassed, do not carry out any work and contact the Comité Français du Butane et du Propane (French
