We had a pallet un-clamp prox. switch go out on our newest MA-500 thur at about 1:00pm. I pulled the cover checked the switch, checked the I/O Monitor and called Morris South. Told the service tech what the alarm was, what I had done to check it out and that I needed that switch and was hurting for the machine. Before 2pm I had a confirmation of warranty status, that a switch was coming UPS Red at n/c and by 11am fri was making chips on the machine again. A service tech will "swing by while in the area" for the paperwork. Just wanted to brag on my distrubitor. Service like that makes the machine just that much sweeter.
