Hello, I am looking for a couple of manuals for a SKT21 with a Yasnac J50-L control. I need a operators manual and a programming manual. We would gladly purchase them if someone has a digital or a hard copy of either one. I have tried Hyundai-Wia with no results. My area Wia rep hasnt got anything either. Also it would be great if someone could post the procedure for backing up the machine parameters for the Yasnac control. Any info would be much appreciated. Thanks, Bob
