A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Make sure that the YELLOW ELEC PUMP pushbutton switch 3804GX on the overhead panel 40VU is in the OFF position (the ON legend is off).
4. Procedure(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Make sure that the YELLOW ELEC PUMP pushbutton switch 3804GX on the overhead panel 40VU is in the OFF position (the ON legend is off).
CAUTION:
IMMEDIATELY OPEN THE CIRCUIT BREAKERS FOR THE YELLOW HYDRAULIC SYSTEM AFTER THE CARGO COMPARTMENT DOOR IS FULLY CLOSED/OPEN. IF THE YELLOW HYDRAULIC PUMP OPERATES ON THE GROUND FOR TOO LONG, DAMAGE TO THE YELLOW HYDRAULIC SYSTEM WILL OCCUR.
NOTE: It is permitted to close the circuit breakers only for the operation of the cargo doors.
Subtask 29-24-00-865-053-A A. Open, safety and tag this(these) circuit breaker(s):
