It is supposed to be air/hydraulic, meaning no hydraulic pumps or anything, just a small air/hydraulic booster unit somewhere on the head. Follow the lines and im sure you will find it. I didnt realize the retract port was air, but that makes sense, would make for a cheaper system. Id try and find this booster unit and cheak fluid level.
Your spindle should be grease packed so only fluids in the machine are way oil, hydraulic fluid in this booster for idlers, and coolant in the chiller. Note that the chiller uses a special type of coolant, not regular antifreeze.
Ok thats great that you have the cable carrier, maybe somebody already added it on your machine. Thats one pain in the ass job you wont have to deal with.
