The Injectors Rail is high-tech device built with high precision components and in

normal conditions/use does not need any maintenance. Nevertheless particularworking conditions (like dirty or contaminated fuel, dirty filter or even absence of a

filter) may require some maintenance, made by trained personnel. We underline inparticular the importance of a very clean working station, in order to avoid small

parts to enter the Rail (this may cause defects).

It is highly forbiddento use chemical products or solvent to clean the internal parts

of the Rail.
