Pressurise all sections of the hydraulic circuit(s) with liquid to their working pressure. Maintain this
pressure for at least 20 s. While pressurised check for leaks.
6.2.2.2 Pressurise all sections of the hydraulic circuit(s) with compressed air. Close off air separator, open all
valves, pressurise the section(s) of the system to (350 10
0
+ ) kPa [(3,5 1 , 0
0
+ ) bar]. Using pressure measurement
equipment with an accuracy of ±1 kPa (± 0,01 bar), record the initial pressure. Take and record another pressure
reading after waiting
