 3. Job Set-up
__________ Subtask 32-31-12-860-051
 A. Aircraft Maintenance Configuration
 (1)
 Make sure that the PTU isolation coupling is disconnected (Ref. TASK 29-23-00-860-001).

 (2)
 Make sure that the electrical circuits are de-energized (Ref. TASK 24-41-00-862-002) or the flight configuration precautions were obeyed (Ref. TASK 32-00-00-860-001).

 (3)
 Make sure that the Green hydraulic system is depressurized (Ref. TASK 29-10-00-864-001).

 (4)
 Make sure that the warning notices are in position to tell persons not to pressurize the Green hydraulic system: - on the panel 40VU in the cockpit, - on the ground service panel of the Green hydraulic system.

 (5)
 Make sure that the reservoir of the Green hydraulic system is depressurized (Ref. TASK 29-14-00-614-001).

 Subtask 32-31-12-560-050
 B. Preparation for Installation
 (1)
 Clean the component interface and/or the adjacent area.

 (2)
 Do an inspection of the component interface and/or the adjacent area.

 (3)
 Make sure that the parts retained from the removed component are clean and in the correct condition.

 (4)
