THREAD TENSION

Correct upper thread tension

The thread tension is normally set on “4” for gen-
eral sewing applications. (Refer to the FABRIC/
THREAD/NEEDLE COMBINATION CHART on
page 26.)
However, the thread tension dial can be used to
adjust the tension of the upper thread in the follow-
ing cases.

*

when using specialty threads or sewing on spe-
cial fabric

*

when sewing gathers, shirring or shell tucks

*

when these settings do not give the desired re-
sult

The upper thread and the bobbin thread should
cross at about the center of the fabric. If the thread
tension is incorrectly set, flat attractive seams will
not be sewn or the fabric will pucker.
