 Subtask 12-12-32-941-064
 A. Safety Precautions
 (1) Put the safety barriers in position.
 (2) Put the warning notice in the cockpit, to tell persons not to operate the landing gear or the landing gear doors.
 (3) Make sure that the ground safety locks are installed on the landing gear (Ref. TASK 32-00-00-481-001).
 Subtask 12-12-32-869-052
 B. Flight Configuration Precautions
 (1) If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then, it is not necessary to operate the LGCIU circuit breakers. 
R R R  (2) If the electrical power is necessary, do the flight configuration precautions with electrical power before you open the LGCIU circuit breakers (Ref. TASK 32-00-00-860-001).

R  A. Preparation for Replenishment 
R  CAUTION : MAKE SURE THAT YOU USE A GAGE WITH THE SPECIFIED PRESSURE_______ 
R  RANGE. THIS IS NECESSARY TO GET AN ACCURATE PRESSURE 
R  MEASUREMENT. 
R  (1) Prepare the standard charging equipment as follows: 
R  (a) Install the pressure gage (10) on the 3-way valve (12). 
R  (b) Connect the 3-way valve (12) to the filling hose (11). 
R  (c) Connect the hydraulic supply hose (18) between the hand pump (17) 
R  and the three-way valve (12). 
R  (d) Connect the hydraulic source hose (16) between the hand pump (17) 
R  and the hydraulic source. 
R  (e) Connect the bleed hose (14) between the 3-way valve (12) and the 
R  drain container (15). 
R  (f) Fill the hydraulic source with HYDRAULIC FLUIDS (Material No. 02-
R  001) or HYDRAULIC FLUIDS (Material No. 02-004). 
R  (g) Open the control valves (20) and (13) and operate the hand pump 
R  (17) to bleed the system. Close the valves (20) and (13). 
R 
R  (2) Install the FILLING ASSEMBLY (M21930) on the charging valve (6) as 
R  follows: 
R  (a) Remove the blanking cap (7) from the charging valve (6). 
R  (b) Remove the cap (1) and the plug (5) from the FILLING ASSEMBLY.
