  Thread breakage in your Brother Sewing Machine can occur due to several reasons. It might be due to improper threading, tangled thread around the spool pin or thread holders, thread tension being too tight, incorrect installation of the needle, or using the wrong type of needle. Ensure you are threading the machine correctly, check for and remove any tangled thread, adjust the thread tension, install the needle properly, and use the recommended needle type 130/705H.

  Skipped stitches on your Brother Sewing Machine can occur if the needle is bent or blunt, installed incorrectly, or is the wrong type. Improper threading or insufficient presser foot pressure can also cause this issue. Replace a bent or blunt needle, ensure the needle is correctly installed, and use the recommended needle type 130/705H. Make sure the machine is threaded correctly and increase the presser foot pressure by turning the pressure adjustment screw clockwise.
