R R R  (d) Connect the connector LP1 of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the LP connector of the hydraulic ground power supply. 
R R R  (e) Connect the HP1 connector of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) to the HP connector of the hydraulic ground power supply. 
R R  (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 (1011GM):
 1_ Remove the Green HP filter (1048GM) (Ref. TASK 29-11-45-610-001). 
R R R 2_  Install a dummy bowl of the TOOL - HYDRAULIC FLUID CHANGE(DH0501) in place of the Green HP filter (1048GM). 
3_ Connect the HP2 line to the dummy bowl and to the valve V2.
 (h) On the LP filter (1002GM):
 1_ Disconnect the tube from the outlet side of the LP filter (1002GM).
 2_ Put a blanking plug in the open port of the tube.
 3_ Connect the LP filter (1002GM) with the LP2 line. Use the LP -HOSES FOR FLUID CHANGE (98D12308351000) for the connection.
R R  (3) Start the hydraulic ground power supply and make sure that the pressure read on the gage of the TOOL - HYDRAULIC FLUID CHANGE (DH0501) is 4.0 bar (58.0150 psi).
 (4) Stop the hydraulic ground power supply.
