I just wanted to say welcome and nice machine. You didn't say if the machine is sewing or has it had time to sit and possibly get frozen. I've not had experience with any of the industrials and my guess would be that a user's manual or service manual would give you the information you need. At one point, there was a link on this site to help find manuals for different models, but most of us have domestic and/or long arm machines for quilting.
