I'm trying to actually sew on my Pfaff 7570 for the first time. The book describes this strange ritual for determining if the bobbin is properly adjusted. I understand the adjustment and how to do it. I understand the test of whether the thread rolls off the right way. BUT.....how on earth do I keep the bobbin inside the case long enough to gently yank on the thread and watch whether or not it drops the right way??
No matter what I do the bobbin falls out of the case. I have tried four different bobbins, all clearly marked Pfaff, and all drop out. I am forced to assume the problem is me.
Please educate me. This is the first machine I've ever used that didn't have a top loading bobbin.
Thanks, Sunny
