For general sewing, set the thread tension dial at AUTO,
which covers a wide range of sewing conditions.

indicated on the LCD screen.

Balanced thread tension

For straight stitch sewing, both needle and bobbin
threads will join at the middle of the fabric.
For zigzag stitch sewing, the needle thread will appear
slightly on the wrong side of the fabric.

Manual thread tension adjustment

You should adjust the tension manually if the LCD screen
shows a tension setting other than AUTO.
You may also need to adjust tension manually depending
on the sewing conditions such as the type of fabric and
number of layers.
If the needle thread is too tight, the bobbin thread
appears on the right side of the fabric.
