THREAD TENSION
Set thread tension according to the fabric you are using with the tension dial.
When doing machine embroidery, the tension dial should be set
somewhere between 2-6.
1 Upper thread tension setting
2 Loose (Decrease thread tension)
3 Tight (Increase thread tension)
4 Upper thread tension dial
* Use the following chart as a guide for tension dial settings.
Turn the dial to the right to increase tension.
Turn the dial to the left to reduce tension.
* If the tension dial is set extremely low, the machine may stop
stitching during sewing. This is not a sign that anything's bro-
ken. It only indicates that your tension is set extremely low.
Simply increase the tension slightly to continue sewing.

poor stitch conformation, puckered
fabric and thread breakage.

half notch when sewing the outline.
