Shift the packer panel lever outward to apply hydraulic pressure to the case end of the packer
panel cylinders. Hold the lever and observe the fluid flow from the open port on the rod end of
the cylinder. The flow of hydraulic fluid should be no more than 2 fluid ounces per minute. A
flow greater than 2
ounces indicates an excessive piston seal leak. If the cylinder does not leak
excessively, continue test.

for the other cylinder.
6.
Shift the packer panel lever inward to retract the packer panel cylinder (to the “interrupted-cycle”
