Setting the StitchBasic operations B-37STARTING TO SEWBSetting the thread tensionYou may need to change the thread tension, depending on thefabric and thread being used.■ Correct thread tensionThe upper thread and the bobbin thread should cross nearthe center of the fabric. Only the upper thread should bevisible from the right side of the fabric, and only thebobbin thread should be visible from the wrong side of thefabric.1 Wrong side of fabric2 Right side of fabric3 Upper thread4 Bobbin thread■ Upper thread is too tightIf the bobbin thread is visible from the right side of thefabric, the upper thread is too tight.Loosen the thread tension.1 Wrong side of fabric2 Right side of fabric3 Upper thread4 Bobbin thread5 The bobbin thread is visible from the right side of thefabric.Pushing the thread tension dial toward the left makes thethread tension looser.■ Upper thread is too looseIf the upper thread is visible from the wrong side of thefabric, the upper thread is too loose.Tighten the thread tension.1 Wrong side of fabric2 Right side of fabric3 Upper thread4 Bobbin thread5 The upper thread is visible from the wrong side of thefabric.Pushing the thread tension dial toward the right makes thethread tension tighter.Note• If the bobbin thread was incorrectly threaded, theupper thread may be too tight. In this case, referto “Installing the bobbin” on page B-15 andrethread the bobbin thread.123 4123 45Note• If the upper thread was incorrectly threaded, theupper thread may be too loose. In this case, referto “Upper Threading” on page B-18 and rethreadthe upper thread.Note• If the upper thread is not threaded correctly orthe bobbin is not installed correctly, it may notbe possible to set the correct thread tension. Ifthe correct thread tension cannot be achieved,rethread the upper thread and insert the bobbincorrectly.5123 4
