  There are several reasons why the thread might break while using your JUKI Sewing Machine. First, the thread tension might be too tight, so try reducing it. Second, the machine might not be threaded correctly, so double-check the threading. Third, make sure the needles are fully inserted into the needle clamp with the flat side to the back. Lastly, ensure you are using the correct needles, specifically needle system 130/705H.
