WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROL SURFACES
_______ ARE CLEAR BEFORE YOU PRESSURIZE/DEPRESSURIZE A HYDRAULIC SYSTEM.
(1) Disconnect the isolation coupling of the PTU (Ref. AMM TASK 29-23-00-860-001).
(2) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(3) On panel 50VU, make sure that the HYD/LEAK MEASUREMENT VALVES/G pushbutton switch is set to on (OFF light not on).
(4) Pressurize the Green hydraulic system from a ground supply or through the PTU (Ref. AMM TASK 29-10-00-863-001) or (Ref. AMM TASK 29-23-00-863-001).
(5) Look for fault indications on the lower ECAM DU.

_______ CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE.
- the system name and the flow arrow of the Green hydraulic system in amber on the lower ECAM DU:
- do a check of the system pressure on the lower ECAM DU and on the system accumulator gage (1072GM).

(1) If the system pressure is more than 1450 psi:
- use the rudder pedals to operate the rudder.
(a) If the rudder operates:
- do a check for continuity between the: the PRESS SW-FLT CTL, G (1151GN) connector A/A and the connector A/C (with the hydraulic system pressurized) (Ref. ASM 29-32/01).
