We just bough and moved in a MITSUBISHI MH-4A HORIZONTAL MACHINING CENTER. Trying to get it running. There is a constant air blow in the spindle, is this normal? The tool air blow does work and turn on and off. There are also two wires that run inside of a pipe on the bottom side of the spindle. They are not plugged into anything? Where do they go and are they related to the spindle air leak?
