Hi all. On all of these types of machines, ( Consew 225, 226 255, Juki 562, 563, Singer 111W, and so on), the belt timing is critical. On the bottom of these machines there are timing marks. Bob at Toledo has the pictures. This timing adjustment is the FIRST thing that you check. If the belt timing is off, then it doesn't matter about any other timing, (hook timing or feed timing), it will not sew correctly. Please make sure the the belt timing is correct before you proceed with any other adjustments. Steve
