1) The Upper and Lower Cutter may be adjusted up and down, and laterally to the right or left.

2) The position of Cutters determines the width of the fabric within the seam. When a butt seam is desired, the cutting surfaces should be positioned approximately in the middle of the Needle Plate Chaining Finger. When a gap seam is desired, the cutting surfaces should be positioned as for a butt then moved to the left about 1/2 the width of the gap required. Lap seams are created by setting the cutting surfaces to the right of the butt seam position. The position of the Cutters will vary with the thickness of fabric. Some trial settings should be made to determine the correct position for each weight of material. Loosely woven materials require a wider setting than tight fabrics.

3) The Lower Cutter Holder slides in the Lower Cutter Holder Support Assembly providing lateral movement to the Lower Cutter. Do not allow the Lower Cutter to push too tightly against the Upper Cutter. If more than a light pressure is required, it usually indicates that the Cutters are dull and should be sharpened.
