Adjusting Thread Tension
Proper thread tension prevents unwanted puckering, poorly-formed stitches, and malfunctions that
can damage the fabric. Test your thread tension on extra materials before sewing on a project.
Tip:
Bottom thread tension is the foundation for proper thread tension. It is addressed in “Loading
the Bobbin Case” on page 31.

Tensioner
1. Loosen the tension knob on the large thread tensioner to set the tension to “1.” The bottom of
the tension knob lines up with the number that the tension is set to.
Note:
Setting “1” is the lowest tension for the machine. This is an ideal starting place to find
the correct top thread tension.
