regulator moves to right and return to the
original position.
Remove the bobbin from the bobbin
winding shaft and cut the thread by cutter.

* Bobbin winding will automatically stop even
while winding, when the winding speed is
reduced due to a load to the bobbin winding
motor caused by thread tangling.

* In general, the same thread is used for both needle and bobbin threads.
* Thin thread and needle will be used for light-weight fabrics and thick thread and needle will be used for
heavy-weight materials.

* Check that the combination of needle and thread is OK by trial sewing on the material which will be sewn.
* Knit needle is good for stretchy fabrics (such as knits) and synthetic fabrics.

* Use thread No. 30 - 90.

* When it is difficult to go over an overlapped section, guide the fabric by hand.
* When sewing decorative stitches or letters (Page 28, 30 and 32), use knit needle for better finish.

How to adjust thread tension

When the needle thread is too
strong:

The bobbin thread will be pulled to the front side of the
fabric. Turn the thread tension adjustment dial towards
"-1" to "-3".

When the needle thread is too
low:

The needle thread will be pulled to the wrong side of
fabric. Turn the thread tension adjustment dial towards
"+1" to "+3".

In case a correct tension setting is not obtained, check
thread paths for both needle and bobbin threads.

Well-balanced thread tension

with each other at the middle of the

fabric thickness. (

)

Zigzag stitch: Needle thread is pulled a little bit to the
wrong side of the fabric.

If the machine is set to “Auto”, it is suitable for most
fabrics. However, adjustment may be necessary
according to fabrics and sewing applications.
If the tension is not correctly set, it will cause

imbalanced stitch formation, puckering, and/or thread

breakage.
