Date: 3/8/13 9:29 AM I would bring your machine into your dealer to have this adjusted. I've never had this problem with any Pfaff, and it shouldn't be happening to yours, so sounds like a tech needs to correct that for you.

I heart Panzy, Pfaff Creative Performance, the sewing machine love of my life! And Rupert (Pfaff 2023), Baby (BL Enlighten), Victor (BLCS), Ash (Bernina 350SE), Pal (Bernina 530), Kee (Bernina 750) and the Featherteen Flock!
Most of all, I heart Woo (HimmyCat). Until we meet again, my beautiful little boy. I love you.
