ADJUSTING THREAD TENSION
NOTE: Your machine’s tension has been
calibrated to ”5” in the factory to suit most
sewing applications.
x Always double check threading before
attempting to adjust thread tension.
x Make a test sample to find proper tension
before sewing on your fabrics.
A balanced stitch:
x A perfect, well balanced stitch will have
needle thread (top) and bobbin thread
(bottom) locked between two layers of
fabric with no loops on top or bottom and
no puckering.
Too much tension:
x Stitch locks appear on top side of fabric.
x To decrease tension, turn dial to a lower
number.
Too little tension:
x A loose stitch appears on bottom side of
fabric.
x To increase tension, turn dial to a higher
number.
