Hi, I'm new to sewing with my industrial Pfaff 335-H2-6/1B S and things were going smoothly until I moved it. My problem is the needle is striking the bobbin case instead of going through the slit to reach the bobbin's thread. It seems like there is a timing issue or that the bobbin is not turning quite far enough around for the needle to be able to go through the opening in the bobbin case. Anyone know how I can adjust the timing or rotation of the bobbin case at home? I can post pictures of it if it helps. Thank you!
