(68.00 DEG.F).
If necessary, adjust the nitrogen pressure (Ref. TASK 12-14-29-614-001).
(3)
Make sure that the pressure on the indicator of the related reservoir is 3.5 +0.3 -0 bar (50.7631 +4.3511 -0.0000 psi). If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002).
Subtask 12-12-29-863-050
D. Pressurize the Auxiliary Braking System.
(1)
Pressurize the Yellow hydraulic system with the Yellow E-pump (Ref. TASK 29-24-00-863-001) to pressurize the brake accumulator system to 206 bar (2987.7766 psi).
(2)
On the panel 110VU, put the parking brake control switch 73GG to the ON position.
(3)
Make sure that the pressure on the triple indicator 60GG shows the left and right pressure values.
(4)
Depressurize the Yellow hydraulic system (Ref. TASK 29-24-00-864-001).
NOTE : Do not depressurize the alternate braking system.
____
(5)
Close the left MLG door (Ref. TASK 32-12-00-410-001).
(6)
Put the warning notices on the panel 40VU in the cockpit to tell persons not to pressurize the hydraulic systems.
4. Procedure
_________
(Ref. Fig. 301/TASK 12-12-29-991-001)
Subtask 12-12-29-611-052
A. Fill the Hydraulic Reservoirs (Refer to the Table).
(1) Remove the hand pump lever 3270GM from the service panel of the Yellow hydraulic system.
(2) On the service panel of the Green hydraulic system, connect the hand pump lever 3270GM to the shaft of the hand pump 1009GM.
(3) Remove the flexible hose 1699GM from the service panel compartment of the Green hydraulic system.
(4) Remove the blanking cap and connect the flexible hose to the fill valve 1698GM. Put the other end in the hydraulic fluid container with HYDRAULIC FLUIDS (Material No. 02-003), HYDRAULIC FLUIDS (Material No. 02-003A), HYDRAULIC FLUIDS (Material No. 02-003B), HYDRAULIC FLUIDS (Material No. 02-003C) or HYDRAULIC FLUIDS (Material No. 02-003D).
(5) Turn the selector 1134GQ to the position that agrees with the system you want to fill.
(6) Make sure that on the quantity indicator 1834GQ the colored light of the system you have selected comes on.
R (7) Fill the hydraulic reservoir.
R R R R R CAUTION : MAKE SURE THAT YOU DO NOT PUT TOO MUCH FLUID IN THE_______ RESERVOIR. IF THE RESERVOIR IS TOO FULL, YOU CANNOT PRESSURIZE IT SUFFICIENTLY. LOW AIR PRESSURE CAN CAUSE THE MESSAGE "RSVR LO AIR PR" TO SHOW IN FLIGHT ON THE UPPER AND LOWER ECAM DISPLAY UNITS.
R
R R (a) Operate the hand pump 1009GM and monitor the increase of the fluid level on the quantity indicator.

(8) Stop the flow of hydraulic fluid when the pointer of the quantity indicator is at the center of the colored line, for the system that you have selected.
R R R NOTE : The hydraulic fluid volume in the reservoirs can change with____ the temperature. For every 10 DEG.C scale Celcius (which is every 18 DEG.F on the scale Fahrenheit) change in outside air temperature:
R R - the volume in the reservoir of the Green hydraulic system can change by 0.85 l (0.2245 USgal)
R R - the volume in the reservoir of the Yellow hydraulic system can change by 0.64 l (0.1690 USgal)
- the volume in the reservoir of the Blue hydraulic system can change by 0.51 l (0.1347 USgal).
NOTE : If the temperature is above 20 DEG.C (68.00 DEG.F) the____ quantity indicator pointer must be in the top half of the applicable scale range.
