Hi, I have a 2 Pfaff machines and know how to wind the bobbin thread, but it doesn't fill the bobbin holder with thread to the fullest on my Pfaff 1475 cd machine. I remember a Pfaff service person changed the settings so that the bobbin really filled up with thread to the very end on my other machine but wondered if anyone knew how to adjust the machine winder to allow for a fuller bobbin on my older machine. Thanks for any help. I'm just trying to avoid taking it to the dealer who is out of town and trying to save some money.
