75shortbox Report post Posted February 1, 2021 Still struggling, trying one change at a time but don't seem to get a different outcome... New needle Re-thread numerous times Adjust thread tension Quote Share this post Link to post Share on other sites
Uwe Report post Posted February 1, 2021 (edited) If you try to remove the material while the hook has a hold of the top thread, you get those threads pulling out of the feed dog. The proper way to remove the material is: keep turning the handwheel until the thread take-up lever is in the very top position, then remove the material. Side note: Those loops on the underside are a problem, too. They indicate that the thread snags at some point as the hook wraps it around the bobbin case.
