Thread Tension Dial
(Fig. 2)
• 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.
