3. Job Set-up
__________
Subtask 32-11-16-941-052
A. Safety Precautions
(1)
Put the safety barriers in position.
(2)
Make sure that the ground safety locks are installed on the landing gear (Ref. TASK 32-00-00-481-001).
(3)
Put a warning notice on the ground service connection to tell persons not to pressurize the Green and Yellow hydraulic systems.
(4)
On the panel 400VU:
-make sure that the landing-gear control-lever 6GA is in the DOWN position
-put a warning notice in position to tell persons not to operate the landing gear.

B. Aircraft Maintenance Configuration
(1)
Disconnect the isolation coupling of the PTU (Ref. TASK 29-23-00-860-001).
(2)
Make sure that the Yellow and Green hydraulic systems are depressurized (Ref. TASK 29-00-00-864-001).
(3)
Depressurize the applicable hydraulic reservoir (Ref. TASK 29-14-00-614-001).
Subtask 32-11-16-582-050
C. Lift the Aircraft
(1) Lift the aircraft on jacks (Ref. TASK 07-11-00-581-001). Subtask 32-11-16-869-054
D. 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.
(2)
If the electrical power is necessary, do the precautions for flight configuration (Ref. TASK 32-00-00-860-001) before you open the LGCIU circuit breakers.
Subtask 32-11-16-865-055
E. Open, safety and tag this(these) circuit breaker(s):
