B. Aircraft Maintenance Configuration
(1) Jack up the front of the aircraft (Ref. TASK 07-11-00-581-003).
NOTE : In the fully extended position of the shock absorber, the NLG____ is automatically centered (the nose wheel steering is in the zero position).
(2) Make sure that the Green hydraulic system is de-pressurized (Ref. TASK 29-10-00-864-001).
(3) Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
