 WARNING: PUT A RAG AROUND THE MANUAL DEPRESSURIZATION VALVES ON THE
_______ RESERVOIR PRESSURIZATION MODULE TO CATCH SPRAY OF HYDRAULIC FLUID. THE SPRAY OF HYDRAULIC FLUID CAN CAUSE INJURIES TO PERSONS. IF THE HYDRAULIC FLUID TOUCHES THE SKIN, FLUSH YOUR SKIN WITH WATER. IF THE HYDRAULIC FLUID TOUCHES YOUR EYES, FLUSH THE EYES WITH WATER AND GET MEDICAL AID.
 (3)  
Slowly open the depressurization (vent) valves to prevent a spray of hydraulic fluid.

 S 492-017

 (4)  
Install the lock on each depressurization (vent) valve when the valve is fully open.

 NOTE: To release the pressure from only one reservoir, put the
____ lock on the applicable depressurization (vent) valve. The pressure is removed from the reservoir when the air flow from the depressurization (vent) valve stops.
 E. Put the Airplane Back to Its Usual Condition
 S 092-018
 (1)  
Remove the lock(s) from the depressurization (vent) valve(s).

 (2)
Do the procedure above to pressurize the hydraulic reservoirs.
