3. Job Set-up
Subtask 31-32-00-860-096-A

A. Aircraft Maintenance Configuration
(1) On the panel 400VU, make sure that the landing gear normal control lever is in the DOWN position.
(2) Put a WARNING NOTICE(S) on the landing gear normal control lever to tell persons not to use it.
(3) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002)
(4) Pressurize the Yellow or Green hydraulic system (Ref. AMM TASK 29-24-00-863-001) or (Ref. AMM TASK 29-23-00-863-001).
(5) Do the EIS start procedure (ECAM only). (Ref. AMM TASK 31-60-00-860-001)
(6) On the center pedestal, on the ECAM control panel, push the HYD key.
(7) On the lower ECAM display unit, the HYD page comes into view. Make sure that the Yellow or the Green hydraulic system is pressurized.
(8) On the center pedestal, make sure that the pitch trim control wheels are at 0 degree.
(9) Take the applicable precautions before you open the LGCIU circuit breakers (Ref. AMM TASK 32-00-00-860-001).
