Page 13: Description Of Spray Gun And Control Module
5. Description of spray gun and control module The function of the manual spray gun is to spray powder electrically charged by a high-voltage unit built into the spray gun that delivers up to 80 kV and 110 µ A. Only pressure on the trigger enables start-up of the power supply and electrical charging of the powder. - Page 14 U/I key for 2 seconds. The output of this screen is similar to the input one. If E screen mentions : “Mach-Jet V > or = 1” this function is available; if E screen mentions “Mach-Jet V = 0”, the gun is not equipped with this function.
