Thread Tension
2-needle top cover-stitch, narrow and wide
Stitch programs 21, 22
If all the thread tensions are set correctly,
the needle threads (blue and green) are
barely visible on the underside of the
fabric. The looper thread (purple) lies slack
between them.
The top cover thread (blue) lies slack
between the needle threads on the top
side of the fabric.
If there are protruding loops in the top
cover thread (blue), adjust the blue thread
tension (45) of the top cover to a higher
setting.
If the top cover thread is barely visible,
adjust the blue thread tension (45) of the
top cover to a lower setting.
The right needle thread (green) is too
loose.
Adjust the green thread tension to a
higher setting.
