    Why does the thread keep breaking on my Gritzner 788?
    • A
      Ashley SellersJul 26, 2025
      If the thread breaks while using your Gritzner Sewing Machine, several factors could be at play. Ensure the needle is correctly threaded. If the thread tension is too tight, adjust it accordingly. Also, double-check that the needle is correctly installed. Inspect the thread spool post and thread tree for any tangled threads and remove them. Finally, ensure you are using a suitable needle for your thread and fabric.

      If your Gritzner Sewing Machine is skipping stitches, the issue might stem from several causes. Start by replacing the needle with a new one and re-installing it correctly. Ensure you are using the correct type of needle (HAx1SP or 130/705H). Double-check that the needle is threaded correctly. Also, verify that the presser foot has sufficient pressure; if not, turn the pressure screw clockwise to increase it.

      If the cloth wrinkles when using your Gritzner Sewing Machine, it might be due to the thread tension being too tight. Reduce the tension, especially when sewing light or thin materials. Also, check the threading and remove any tangled threads before re-threading the needle correctly.
