I also have a Pfaff 145-H3-6/01. I am able to adjust the height correctly, but I need to adjust them forward and backwards. The problem I am having now is that the needle hit the feed dog when it comes down to pick up the bobbin thread. It doesn't go into the hole directly. How do I adjust the feed dog forward or back ward to get the needle to go directly into the hole to pick up the bobin thread.
