Hi. I just purchased a used mini mill. I have no reference for what is normal, but the pump doesn't push out the coolant with much force at all. It won't even reach the tips of my shorter tools.
I know where the metal screen is, and it is clear, but is there any other filter or anything that might be partially plugged?
Also, the first thing I cut was some plastic block. Is it okay to let the little plastic pieces into the coolant which will float, as compared to metal that will sink?
