Crawford/Burnerd Power Collet Chuck - hydraulic intensifier question...

Hi guys,
I have recently acquired a lathe with a power Crawford/Burnerd collet chuck. I'm struggling to track detailed guidance for the chuck and want to replace the hydraulic line running between the pneumatic -> hydraulic intensifier and the chuck. If anyone has done this before I'd like to know a couple of things:

1) With no air supplied and no collet in the chuck is there any static hydraulic pressure in the system?
2) What is the drain, refill, bleed process?

Thanks in advance...
