The Sewing Guy is trying to drum up business. Why else would he come here, assuming that we "quilters" know nothing about taking care of our machines, (old, new, indifferent) and tell us to turn them on and spray them?
It's either that, or he's not read one other post on this board where we tell folks how to repair, clean, take care of their machines.
The last "Guy"....well...I won't go there.
