* Adjusting the thread tension for purl stitch:
1) Adjust the bobbin thread tension to approx. 15 to 20g by adjusting screw ® of the
bobbin case.
2) Adjust tension controller No. 1 ® for proper needle thread tension so that the bar-tack
part is formed by well-shaped whip stitches. If the tension is too low, bar tacking seam
may form thread knots on the rear face of fabric.
