Close the FWD or Aft Cargo-Compartment Door with the Yellow Electric Pump
WARNING:
BEFORE YOU CLOSE THE CARGO DOOR, BLEED THE DOOR HYDRAULIC SYSTEM IF:
- THE DOOR WAS OPEN FOR MAINTENANCE WORK ON THE YELLOW HYDRAULIC SYSTEM, AND/OR
- THE DOOR WAS OPEN FOR MORE THAN 12 HOURS.
CAUTION:
YOU MUST CLOSE THE CARGO COMPARTMENT DOORS BEFORE THE WIND SPEED IS MORE THAN 65 KNOTS TO PREVENT DAMAGE TO THE DOOR OR TO THE AIRCRAFT STRUCTURE.
CAUTION:
WHEN YOU OPEN AND CLOSE THE CARGO DOORS, MAKE SURE THAT THE ACCESS PLATFORM IS AT THE CORRECT HEIGHT. IF IT IS TOO HIGH, IT WILL PREVENT FREE MOVEMENT OF THE DOORS.

A. Aircraft Maintenance Configuration
(1) Make sure that the Yellow hydraulic system reservoir is pressurized (Ref. AMM TASK 29-14-00-614-002).
(2) Make sure that the level of the hydraulic fluid in the Yellow reservoir is correct (Ref. AMM TASK 12-12-29-611-001) or (Ref. AMM TASK 12-12-29-611-002).
(3) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(4) Make sure that an ACCESS PLATFORM 2M (6 FT) is in position below the FWD or Aft cargo-compartment door.
Subtask 52-30-00-865-051-A (1) Make sure that the Yellow hydraulic system reservoir is pressurized (Ref. AMM TASK 29-14-00-614-002).

A. Aircraft Maintenance Configuration
(2) If installed, remove the safety support equipment from the opened cargo door (Ref. AMM TASK 52-30-00-080-001).
Subtask 52-30-00-869-052-D WARNING:
BEFORE YOU CLOSE THE CARGO DOOR, BLEED THE DOOR HYDRAULIC SYSTEM IF:
(1) If necessary, do the bleed procedure (Ref. AMM TASK 52-36-00-600-001). - THE DOOR WAS OPEN FOR MAINTENANCE WORK ON THE YELLOW HYDRAULIC SYSTEM, AND/OR
- THE DOOR WAS OPEN FOR MORE THAN 12 HOURS.
(2) If installed, remove the safety support equipment from the opened cargo door (Ref. AMM TASK 52-30-00-080-001).
B. Close the FWD or Aft Cargo-Compartment Door
5. Close-upWARNING:
MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
CAUTION:
YOU MUST CLOSE THE CARGO COMPARTMENT DOORS BEFORE THE WIND SPEED IS MORE THAN 65 KNOTS TO PREVENT DAMAGE TO THE DOOR OR TO THE AIRCRAFT STRUCTURE.
(1) Move the selector of the control panel to the CLOSE position and hold it until the cargo door is closed. NOTE: The green indicator light goes off when the cargo door starts to close.
(2) Release the selector when the cargo door is fully closed. NOTE: The selector must go back automatically to the NEUTRAL position. If not, put it manually to the NEUTRAL position to prevent a permanent operation of the yellow electric pump.
(3) Pull the door handle down to the LOCKED position and push it into the recess of the door structure. NOTE: Manually lock the hydraulically closed cargo door in 3 seconds maximum. This prevents movement of the unlocked cargo door in the open direction because of gravity.
(4) Make sure that you can see the green mark of each safety cam through the indication windows of the access panel 825AR and/or 826AR. Subtask 52-30-00-860-053-A
