I just moved my Mazak VQC 15/40 and after powering up it has code 201 low hydraulic pressure. All axis movements appear normal, but the code allows the spindle to run for a minute them shuts it down. I hear a gurgling sound that wasn't there the day before so I imagine that air is trapped in the pump?

Any ideas as to how to bleed or otherwise get this thing going again? The guys that moved it spilled a lot of fluid out when they disconnected the lines, but I refilled the tank and am at a loss as to how to proceed
