How to adjust thread tension
When the needle thread is too
strong:
The bobbin thread will be pulled to the front side of the
fabric. Turn the thread tension adjustment dial towards
"-1" to "-3".
When the needle thread is too
low:
The needle thread will be pulled to the wrong side of
fabric. Turn the thread tension adjustment dial towards
"+1" to "+3".
In case a correct tension setting is not obtained, check
thread paths for both needle and bobbin threads.

with each other at the middle of the
fabric thickness. (

)
Zigzag stitch: Needle thread is pulled a little bit to the
wrong side of the fabric.
If the machine is set to “Auto”, it is suitable for most
fabrics. However, adjustment may be necessary
according to fabrics and sewing applications.
If the tension is not correctly set, it will cause
imbalanced stitch formation, puckering, and/or thread
breakage.
