6. How to adjust stitch length
The feed regulator dial on this machine is pre-set to
3mm for normal sewing condition. Since the adjust­
ment can be made easily, adjust the stitch length to
4mm when sewing heavy weight fabrics such as
quilting and to 2mm when sewing light weight
fabrics such as lining fabric, crepe, etc. and you will
obtain excellent seams without puckerings.
