R WARNING : OBEY THE HYDRAULIC SAFETY PROCEDURES.
_______
R (1) Obey the hydraulic safety procedures (Ref. TASK 29-00-00-910-002).
R (2) Put a WARNING NOTICE in position to tell persons not to pressurize
R the Blue hydraulic system:
R - in the cockpit on the hydraulic section 40VU of the overhead panel
R - on the ground service panel of the Blue hydraulic system.

 (3) Make sure that the Blue hydraulic system is depressurized and put it in the maintenance configuration. (Ref. TASK 29-00-00-864-001).
 (4) Depressurize the reservoir of the Blue hydraulic system (Ref. TASK 29-14-00-614-001).
 (5) Put the ACCESS PLATFORM 3M (10 FT) in position.
 (6) Put the CONTAINER 1 L (1/4 USGAL) below the filter to collect the unwanted hydraulic fluid.
