 A. Installation of the Fluid Sampling Valve
 (1)
 Clean the component interface and/or the adjacent area.

 (2)
 Do an inspection of the component interface and/or the adjacent area.

 (3)
 Remove the blanking plugs from the fluid sampling valve (1) and the manifold.

 (4)
 Apply HYDRAULIC FLUIDS (Material No. 02-003) to the threads of the fluid sampling valve (1) and to the new O-ring (2).

 (5)
 Put the O-ring (2) in position on the fluid sampling valve (1).

 (6)
 Install the fluid sampling valve (1) on the manifold.

 (7)
