Stitch formation correction measures

cover stitch

Program 02

When all tensions are correctly set, the needle 

threads (green and blue) are just slightly visible 

on the underside of the fabric. The looper 

thread (violet) is situated loosely in between.

The right needle thread (green) is too loose, 

causing large loops on the underside of the 

fabric.

Set the green thread tension to a higher value.

The needle threads (green and blue) are set too 

tightly causing folds in the fabric.

Set the green and blue thread tension to a lower 

value.
