The upper thread tension is changed using the thread tension dial.
When doing machine embroidery, the tension dial should be set somewhere between 2 to 6.
(1) Loosen (Decrease the number)
(2) Tighten (Increase the number)
(3) Thread tension dial
If the stitches appear loose, turn the tension up one notch and embroider again.
Correct thread tension
The thread tension is correct when upper thread is just visible on the wrong side (bottom) of the fabric.
(1) Right side (top) of fabric
(2) Wrong side (bottom) of fabric
Upper thread is too tight
The bobbin thread will be visible on the right side (top) of the fabric. In this instance, decrease the upper thread tension.
(1) Right side (top) of fabric
(2) Wrong side (bottom) of fabric
Upper thread is too loose
The upper thread has slack. In this instance, increase the upper thread tension.
(1) Right side (top) of fabric
(2) Wrong side (bottom) of fabric
If the upper thread is not threaded correctly or the bobbin is not installed correctly, it may not be possible to set the correct thread tension. If the correct thread tension cannot be achieved, rethread the upper thread and insert the bobbin correctly.
