R (b) If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-13-44-610-001).
R R R (c) If the red indicator button is not out (after the operational test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the clogging indicator (Ref. TASK 29-13-44-960-001).
(2) For the high pressure (delivery) filter (3048GM):
(a) Make sure that the red indicator button is not out. If the red indicator button is out, do these steps: - push the red indicator button to set it again - do an operational test of the Yellow hydraulic system (Ref. TASK 29-13-00-710-002).
R (b) If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-13-45-610-001).
R R (c) If the red indicator is not out (after the operational test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the clogging indicator (Ref. TASK 29-13-45-960-001).

E. Do a Check of the Filters in the Reservoir Pressurization Unit (1360GM) and the Reservoir Filling System
(1) For the reservoir pressurization filter:
(a) Make sure that the red indicator button is not out. If the red indicator button is out, do these steps: - push the red indicator button to set it again - do a functional test of the pressurizing system for the reservoirs (Ref. TASK 29-14-00-720-001).
(b) If the red indicator button is out (after the functional test), replace the filter element (Ref. TASK 29-14-41-610-002).
(c) If the red indicator button is not out (after the functional test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the filter assembly (Ref. TASK 29-11-44-610-001).

GREEN MAIN HYDRAULIC POWER - DESCRIPTION AND OPERATION______________________________________________________
1. General_______
R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 301-399,
The Green main hydraulic system is one of the three systems which supply the aircraft with hydraulic power. It supplies: - the landing gear and doors (including nosewheel steering), - the normal braking system, - the left (No. 1) engine thrust reverser, - some of the flight controls, - the power transfer unit (PTU).
Most of the components of the system are installed in the main landing gear compartment. The system is kept physically apart from the other two systems where possible. The system is hydraulically isolated from the other two systems. It is not possible for fluid to go from one system into another.
