STITCH SETTINGS

Setting the Thread Tension

You may need to change the thread tension, depending on the fabric and thread being used. Follow the steps below to make any necessary changes.

Proper 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.

Upper Thread is Too Tight

If the bobbin thread is visible on the right side of the fabric, the upper thread is too tight.

Note

If the bobbin thread was incorrectly threaded, the upper thread may appear to be too tight. In this case, refer to “Setting the Bobbin” of “Basic operations” and rethread the bobbin thread.

Memo

When you finish sewing, remove the bobbin cover and then make sure that the thread is shown as below. If the thread is not shown as below, the thread is not inserted through the tension-adjusting spring of the bobbin case correctly. Reinsert the thread correctly. For details, refer to “Setting the Bobbin” of “Basic operations”.

Upper Thread is Too Loose

If the upper thread is visible from the wrong side of the fabric, the upper thread is too loose.

Note

If the upper thread was incorrectly threaded, the upper thread may appear to be too loose. In this case, refer to “Upper Threading” of “Basic operations” and rethread the upper thread.
