7. How to adjust stitch length

The stitch length dial on this machine is pre-set to 3mm for
normal sewing condition. Since the adjustment 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 ex­
cellent seams without puckering.
