Tension of the Thread
The tension of the thread will affect the quality of
your stitches. You may need to adjust it when you
change fabric or thread.
Memo
●
We recommend that you do a test sample
on scrap of a fabric before you start to sew.
■
Possible Problems If the Tension is Wrong
Upper tension is too tight.
Loops will appear on the surface of the fabric.
Solution
Reduce the tension by turning the Upper
Tension Control Dial to a lower number.
Upper tension is too loose.
Loops appear on the back of the fabric.
Solution
Increase the tension by turning the Upper
Tension Control Dial to a higher number.
Correct tension
Correct tension is important as too much or too
little tension will weaken your seams or cause
puckers on your fabric.
