* When having trouble in feeding fabrics, turn the dial to larger number to have longer stitch length and support sewing
by hands.
* When sewing heavy fabrics, it will cause skipped stitches, damage of needles or breakage of threads.
* Numbers in this chart are approximate figures. Please adjust dials for your preference.
