Depending on the type of thread you will use, you will need to adjust the tension knobs. For the best
quality design, make the following tension adjustments when necessary.
• For metallic and polyester threads, rotate the tension knob one time counterclockwise.
• For light color rayon threads, rotate the tension knob one to two times counterclockwise.
• For white rayon thread, rotate the tension knob one time counterclockwise.
• For medium color rayon threads, rotate the tension knob one to two times
counterclockwise.
• For dark color rayon threads, rotate the tension knob two to three times counterclockwise.
• For black rayon thread, rotate the tension knob three times counter clockwise.

Figure 121
Proper bobbin tension is essential for quality embroidery.
If tension is incorrect, you may begin to experience
frequent thread breaks. You can ne-tune the bobbin
tension by adjusting the large screw on your bobbin case.
Rotate the screw counterclockwise to loosen the tension,
or rotate the screw clockwise to tighten the tension. See
Figure 121.
When too much bobbin is showing on the back of your
design, your bobbin tension is too loose. To resolve this,
take your bobbin case and tighten it by rotating the large
screw clockwise. This screw is labeled “Tension Adjusting
Screw” in Figure 122.
When too much bobbin is showing, it could also mean
your top tension is too tight, so your top thread may
appear smaller than your bobbin thread. You may need to
slightly tighten the bobbin tension when stitching caps,
thick materials or small details. See Figure 123.
When too little bobbin is showing on the back of your
design, your bobbin is too tight. To resolve this, you will
need to loosen the bobbin case by rotating the large
