Presser foot pressure
The presser foot pressure has been pre-set to the
standard value ”N”. In most cases, you do not need
to adjust the presser foot pressure. When using
specialty techniques, or when sewing on very light
or heavy fabric, adjusting the pressure can improve
the result.
For very light fabrics, loosen the pressure by
turning the dial counterclockwise.
Note: If the dial is turned counterclockwise too much, it
could come off. If this happens, simply replace the dial
and turn it clockwise until it stays in place.
For heavy fabric, tighten the pressure by turning
the dial clockwise.
Note: If the dial is turned clockwise until it comes to a
stop, it has reached the maximum pressure available.
Do not try to turn the dial any further!
Thread tension
To set the thread tension, turn the dial on top of the
machine. Depending on the fabric, batting, thread,
etc, the tension may need to be adjusted.
For the best stitch appearance and durability, make
sure the needle thread tension is correctly adjusted.
For general sewing, the threads evenly meet
between the two layers of fabric.
If the bobbin thread is visible on the top side of
the fabric, the needle thread tension is too tight.
Reduce the needle thread tension.
If top thread is visible on the underside of the
fabric, the needle thread tension is too loose.
Increase the needle thread tension.
For decorative stitches and buttonholes, the top
thread should be visible on the underside of the
fabric.
Make a few tests on a scrap piece of the fabric you
are going to sew and check the tension.
