B. Aircraft Maintenance Configuration
(1)
Disconnect the isolation coupling of the PTU (Ref. TASK 29-23-00-860-001).
(2)
Make sure that the Yellow and Green hydraulic systems are depressurized (Ref. TASK 29-00-00-864-001) and (Ref. TASK 29-10-00-864-002).
(3)
Depressurize the Green and Yellow hydraulic reservoirs (Ref. TASK 29-14-00-614-001).
(4)
If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then, it is not necessary to operate the LGCIU circuit breakers.
(5)
If the electrical power is necessary, do the precautions for flight configuration (Ref. TASK 32-00-00-860-001) before you open the LGCIU circuit breakers.
