Depending on the needle positions used, this machine can sew 2-/3- and 4-Thread Overlock Stitches at a width
of 4mm and 6 mm.
Also, for overedging heavyweight fabrics, the seam width can be increased still more by turning the cutting width
dial. (Refer page 36)

The thread tension becomes tighter as the dials are
tumed to higher numbers. The tension settings shown
on this page as well as throughout the Instruction
book are suggested guides. Adjust thread tensions to
suit the fabric and size of thread of thread used. For
best results make tension adjustments in small
increments of no greater than half a number at a time.
–
When sewing chainstitches, set stitch length to
over 2 mm.
–
When sewing coverstitches, set stitch length to
over "•" (2.5 mm).
