(3) Make sure that the pressure on the indicator of the related reservoir is 3.5 +0.3 bar or -0 bar (50.7632+4.3511 psi or +0.0000 psi). If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002-A).

Subtask 12-12-29-863-050-A

D. Pressurize the Auxiliary Braking System.

(1) Pressurize the Yellow hydraulic system with the Yellow E-pump (Ref. TASK 29-24-00-863-001-A) topressurize 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-A).

NOTE : Do not depressurize the alternate braking system.

4. Procedure

(Ref. Fig. 12-12-29-991-00100-A - Ground Service Panel of the Green Hydraulic System)

Subtask 12-12-29-611-052-A

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 shaftof the hand pump 1009GM.

(3) Remove the flexible hose 1699GM from the service panel compartment of the Green hydraulic system.

Revision n˚: 12


(4) Remove the blanking cap and connect the flexible hose to the fill valve 1698GM. Put the other end inthe CONTAINER - HYDRAULIC FLUID RESISTANT with one of these hydraulic fluids:. HYDRAULIC FLUIDS (Material No: 02-003). HYDRAULIC FLUIDS (Material No: 02-003A). HYDRAULIC FLUIDS (Material No: 02-003B). HYDRAULIC FLUIDS (Material No: 02-003C). HYDRAULIC FLUIDS (Material No: 02-003D). HYDRAULIC FLUIDS (Material No: 02-003E) .

(5) Turn the selector 1134GQ to the position that is correct for the system you will fill.

(6) Make sure that, on the quantity indicator 1834GQ, the colored light of the related system comes on.

(7) Fill the hydraulic reservoir:

CAUTION : MAKE SURE THAT YOU DO NOT PUT TOO MUCH FLUID IN THE RESERVOIR. IFTHE RESERVOIR IS TOO FULL, YOU CANNOT PRESSURIZE IT SUFFICIENTLY. LOWAIR PRESSURE CAN CAUSE THE MESSAGE ”RSVR LO AIR PR” TO SHOW IN FLIGHTON THE UPPER AND LOWER ECAM DISPLAY UNITS.

(a) Operate the hand pump 1009GM.

(b) Monitor the increase of the fluid level of the related system on the quantity indicator and do thesesteps:

1 Stop the flow of the hydraulic fluid when the pointer is almost to the fill level given in thetable.

2 Slowly continue to fill again, until the pointer shows almost to the fill level given in thetable.

NOTE : Each open MLG decrases the volume in the green reservoir by 0.25 l (0.0660USgal).

NOTE : Each open cargo door decrases the volume in the yellow reservoir by 0.2 l (0.0528USgal).

NOTE : The hydraulic fluid volume in the reservoirs can change with the temperature. Foreach 10 DEG.C scale Celcius (which is each 18 DEG.F on the scale Fahrenheit)change in outside air temperature:

. The volume in the reservoir of the Green hydraulic system can change by 0.5 l(0.1321 USgal)

. The volume in the reservoir of the Yellow hydraulic system can change by 0.5 l(0.1321 USgal)

. The volume in the reservoir of the Blue hydraulic system can change by 0.25 l(0.0660 USgal).

NOTE : If the temperature is above 20 DEG.C (68.00 DEG.F) the quantity indicator pointermust be in the top half of the related scale range.
