Balancing Needle Thread Tension
ITl
Correct tension
The thread tension is adjusted depending on
the sewing materials, layers of fabric and
sewing method.
For an ideal zigzag stitch, the bobbin thread
does not show on the right side (top side) of
the fabric, and the needle thread shows
slightly on the wrong side (bottom side) of the
fabric.

Adjusting Bobbin Thread Tension
For general sewing, the bobbin thread tension
does not need to adjust. However, you can adjust
the bobbin thread tension for a specific sewing
need.
Turn the adjusting screw to the right to tighten or,
to the left to loosen the tension.
