Do these steps before you fill the reservoir in the right hydraulic system:
(a) Make sure the pressure gage on the brake accumulator, in the aft left wing-to-body fairing, shows a minimum of 2500 psi.
CAUTION: YOU MUST HAVE FLUID IN THE RIGHT SYSTEM RESERVOIR, BEFORE
_______ YOU OPERATE THE HYDRAULIC PUMPS OR YOU MUST PRESSURIZE THE RIGHT SYSTEM WITH A HYDRAULIC SERVICE CART. IF YOU OPERATE THE HYDRAULIC PUMPS WITHOUT SUFFICIENT FLUID IN THE RESERVOIR, YOU CAN CAUSE DAMAGE TO THE PUMPS.
(b)
If the pressure gage does not show a minimum of 2500 psi, pressurize the right hydraulic system (AMM 29-11-00/201).
(c)
Remove hydraulic power, after the right hydraulic system pressurizes the brake accumulator to a minimum of 2500 psi (AMM 29-11-00/201).

WARNING: USE THE PROCEDURE IN AMM 32-00-15 TO REMOVE THE DOOR
_______ LOCKS. THE DOORS OPEN AND CLOSE QUICKLY AND CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
(d) For the left or right system, remove the door locks from the landing gear doors and close the doors (AMM 32-00-15/201).
S 493-052
CAUTION: USE CLEAN HYDRAULIC FLUID, BMS 3-11, AND CLEAN EQUIPMENT TO
_______ FILL THE HYDRAULIC SYSTEM RESERVOIRS. IF YOU DO NOT USE CLEAN HYDRAULIC FLUID AND EQUIPMENT, CONTAMINATION OF THE HYDRAULIC SYSTEM CAN OCCUR.
ALL CURRENTLY QUALIFIED BMS 3-11, TYPE IV HYDRAULIC FLUIDS ARE INTERCHANGEABLE AND INTERMIXABLE IN ANY PROPORTION.
(4) Connect the ground service cart to the pressure fill connection.
S 613-051
WARNING: BE CAREFUL TO NOT FILL THE RESERVOIR TO MORE THAN THE NECESSARY
_______ LEVEL. IF YOU PUT TOO MUCH FLUID IN THE RESERVOIRS, THE FLUID CAN GO INTO THE DUCTS OF THE PNEUMATIC SYSTEM AND THE AIR CONDITIONING PACKS. THIS CAN CAUSE SMOKE AND DANGEROUS FUMES TO GO INTO THE FLIGHT COMPARTMENT AND THE PASSENGER CABIN. IF CONTAMINATION OF THE PNEUMATIC SYSTEM OCCURS AGAIN AND AGAIN, IT CAN CAUSE DAMAGE TO THE TITANIUM DUCTS.
(5) Do these steps for each hydraulic reservoir you will fill:
(a) Put the reservoir fill valve to the position (L, R, or C) for the hydraulic system in which you will fill the reservoir.
