OVERVIEW12Stitch Length/Rolled HemABABStitch WidthThe stitch length / rolled hem adjusting dial is conveniently located just to theleft of the front cover, near the base plate (fig. A). The dial shows two stitch-length ranges, each numbered from 1, for the shortest stitch, to 4 for thelongest. As the dial indicates, one range is for standard sewing and one is forrolled edging or narrow seaming.Simply turn the dial aligning the desired setting with the indicator mark on themachine. A stitch length of 3mm, or about 10 stitches per inch is ideal forseaming and overedging most fabrics. For overedging or seaming very light-weight fabrics, you may prefer a shorter stitch length. When sewing heavierfabrics, you may choose to lengthen the stitch (fig. B).The stitch width adjusting dial is located above the stitch length dial (fig. A). Thestitch width displays two sets of numbers, indicating two width ranges. for over-lock stitches. The larger numbers at each end of the dial, 5.5 and 7.5mm,denote the stitch width when the 0-1 (left hand) needle is in use. The smallernumbers, 3.0 and 5.0mm, apply when only the 0-2 (right-hand) needle is in usefor forming a 3-thread stitch. The "M" setting (3.5) is for the rolled edge.Adjusting the stitch width moves the upper cutting blade. It also moves thestitch fingers further apart or closer together for complete fabric support withany stitch width.The stitch width is infinitely variable between either end of the range. Simplyturn the dial aligning the desired setting with the indicator mark on the machine.Use a wider stitch on loosely woven fabrics. You may prefer a narrower stitchwidth on knits, tightly woven, or sheer fabrics (fig. B).
