Upper thread tension
Lower thread tension
Please note:
Basic thread tension setting: "4". (1)
To increase the tension, turn the dial to the next number up.
To reduce the tension, turn the dial to the next number down.
A. Normal thread tension for straight stitch sewing.
B. Thread tension too loose for straight stitch sewing. Turn dial
to higher number.
C. Thread tension too tight for straight stitch sewing. Turn dial to
lower number.
D. Normal thread tension for zig zag and decorative sewing.
Correct thread tension is when a small amount of the upper
thread appears on the bottom side of fabric.
If the thread is looping or birdnesting on the underside of the
fabric, this is an indication that the upper machine tension is not
threaded correctly.
-.
- There is no single tension setting appropriate for all stitch
functions, thread or fabric.
- A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch construction sewing.
- 90% of all sewing will be between "3" and "5".
- For zig zag and decorative sewing stitch functions, thread
tension should generally be less than for straight stitch sewing.
- For all decorative sewing you will always obtain a nicer stitch
and less fabric puckering when the upper thread appears on
the bottom side of your fabric.
- If the thread is looping or birdnesting on the top of the fabric,
this is an indication that the bobbin thread has not been
threaded correctly.
The bobbin tension has been set correctly at the factory, so you
do not need to adjust it.
Proper tension setting is important for strong seams
