Thread Tension Dial

Auto Tension (Model 3230 only)
The "Auto" setting on the tension dial is suitable for most
sewing techniques. The setting mark
with "Auto" unless otherwise indicated.
Tension Adjustment for Straight Stitch
In straight seams, the needle thread

thread should lock together in the center of the two
layers of fabric. (Model 3210 only – Needle thread
tension can range from 3-5 with setting mark
on 4.) If you look at the top and bottom of the stitch, you
will notice that there are no gaps; each stitch is smooth
and even.
When adjusting needle thread tension, the higher the
number, the tighter the needle thread. Here are some
reasons you may need to change the thread tension dial:
1. The fabric is stiff or heavy.
2. You are sewing more than two layers of fabric.
3. The stitch you are using needs the threads to not
lock together in the center of the fabric.
• Tension is too tight
The bobbin thread shows through on the topside of the
fabric and it will feel bumpy.
Turn the dial to align the setting mark with a lower
number to loosen the needle thread tension.
• Tension is too loose
The needle thread shows through on the underside of the
fabric and it will feel bumpy.
Turn the dial to align the setting mark with a higher
number to tighten the needle thread tension.
• Adjusting Tension for Zigzag and Embroidery
The upper thread tension should be slightly looser when
sewing a zigzag or a satin stitch. The upper thread
should appear slightly on the underside of the fabric.
