Needle/Lower looper thread tension is out of

The illustration shows sewing results when the
needle thread tension is too tight and/or lower looper
thread tension is too loose.
Remedy:
Loosen needle thread tension and/or tighten lower
looper thread tension.
Left needle thread tension dial
Right needle thread tension dial
Lower looper thread tension dial
Correct tension for rolled hem
* The illustration shows sewing result with correct
tension settings.
Set the changeable thread guide at the lowered
position.
Other settings are same as the 3-threads rolled hem
(See page 76).
However, tension adjustment may be required de-
pending on the type and thickness of fabric and
threads being used.
Make a trial sewing with the fabric and threads you
wish to use to obtain in the best results by adjusting
tension.
