Adjusting the Thread Tension Adjusting the Thread Tension You may need to change the thread tension, depending on the fabric and thread being used. ■ Correct thread tension The upper thread and the bobbin thread should cross near the center of the fabric. Only the upper thread should be visible from the right side of the fabric, and only the bobbin thread should be visible from the wrong side of the fabric. 1 Wrong side of fabric 1 2 Right side of fabric 3 Upper thread 2 4 Bobbin thread 3 4 Turn the thread tension dial clockwise to tighten the upper thread tension. Note • If the upper thread is not threaded correctly or the bobbin is not installed correctly, it may not be possible to set the correct thread tension. If the correct thread tension cannot be achieved, rethread the upper thread and insert the bobbin correctly. ■ Upper thread is too tight If the bobbin thread is visible from the right side of the fabric, the upper thread is too tight. Loosen the thread tension. Note • If the bobbin thread was incorrectly threaded, the upper thread may be too tight. In this case, refer to "Installing the bobbin" on page 22 and rethread the bobbin thread. 1 Wrong side of fabric 1 2 Right side of fabric 3 Upper thread 2 4 Bobbin thread 3 5 The bobbin thread is visible 4 5 from the right side of the fabric.
