(c)
 Set the hydraulic ground power supply to the "cart reservoir" configuration.

 (d)
 Open the by-pass valve.

 (e)
 Start the hydraulic ground power supply.

 (f)
 Adjust the hydraulic ground power supply to a flow of 45/lmn approx. and stop the hydraulic ground power supply.

 WARNING : PROTECT YOUR HANDS AND FACE FROM THE GAS WHICH COMES
_______ OUT WHEN YOU OPEN THE MANUAL DEPRESSURIZATION VALVE OF THE RESERVOIRS. IT IS POSSIBLE THAT THE GAS IS HOT AND CONTAINS HYDRAULIC FLUID.

 (2) Set the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the correct configuration. (Ref. Fig. 318/TASK 12-36-29-991-018, 319/TASK 12-36-29-991-024, 320/TASK 12-36-29-991-019)
 (a)
 Put the TOOL - HYDRAULIC FLUID CHANGE (DH0501) in a position, where you can monitor the hydraulic fluid quantity indicator 1834GQ on the Green ground service panel during the procedure.

 (b)
 Put the selector valve 1134GQ in the position for the Yellow hydraulic reservoir.

 NOTE : Make sure that the Yellow reservoir depressurization valve
____ is open when you set the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the correct configuration.
 (c)
 On the TOOL - HYDRAULIC FLUID CHANGE (DH0501) close the valve V1.

 (d)
 Connect the connector LP1 of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the LP connector of the hydraulic ground power supply.

 (e)
 Connect the HP1 connector of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the HP connector of the hydraulic ground power supply.

 (f)
 Connect the LP3 connector of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the suction connector of the ground service panel.

 (g)
 On the HP manifold (3011GM):

 (h)
 On the LP filter (3002GM): 1 Put a container below the LP filter (3002GM).

 1_ Remove the Yellow HP filter (3048GM) (Ref. TASK 29-13-45-610-
001).
 2_ Install a dummy bowl of the TOOL - HYDRAULIC FLUID CHANGE
 (DH0501) in place of the Yellow HP filter (3048GM).
 3_ Connect the HP2 line to the dummy bowl and to the valve V2.

_ 2 Cut, remove and discard the lockwire between the filter bowl
_
 and the filter head. 3 Remove the filter bowl.
