The pump lever must be actuated about once per second until fuel emerges from the nozzle. The opening pressure is read off the manometer. To check the spray pattern, switch off the pressure gauge and move the pump lever quickly (approx. 4 strokes/seconds). The fuel jet must emerge without scattering in the form of a narrow cone. To check the nozzle seat for leaks, the nozzle is subjected to a pressure of approx. 10 bar below the opening pressure. No fuel should leak out. Li.
