Thread Tension; Correct Tension; Tightening The Upper Thread Tension; Loosening The Upper Thread Tension - Brother PE-400D Operation Manual

THREAD TENSION

Use the tension dial to adjust thread tension in accordance to the fabric and thread you are using.
- For stitches with fairly small stitch lengths, such as the satin stitch and buttonhole stitching, you can
get a better stitch by slightly reducing tension.
- Use the tension dial to adjust thread tension for lightweight or heavyweight fabrics and for gathers.

Correct tension

* Thread tension is automatically set to the most appropriate
point irrespective of the chosen fabric and thread.
Correct tension is important because too much or too little
tension will weaken your seams or cause your fabric to pucker.

* The setting on the tension dial is a guide for working normal fabrics (medium weight). However,
the actual stitch tension you'll want to use will vary according to the fabric and thread you are using, so
you should always sew a stitch sample and adjust stitch tension before beginning on the actual piece
to be worked.
* The machine may stop sewing if tension is set extremely low. This is not a sign that there is anything
wrong with your machine. Simply adjust to the correct stitch tension and begin again.
