Sewing test
After threading make a trial run. Always use a double layer of fabric to check
the stitch formation and thread tension properly.
• Switch the machine on (“ I “).).
• Set all tensions to 4.
• Stitch length, differential, cutting width.
• Lower the knife.
• Lower the upper presser foot.
• Raise the front of the presser foot slightly with your thumb and position the
fabric under the foot just up to the knife. Sew.
• At the end of the seam continue sewing a 5 - 6 cm (2 - 2 1/2’’) long thread
chain (A).
• Holding the fabric in one hand, pull the thread chain over the thread cutter (B).
** When using cordonnet or the like, pull out the thread chain carefully (C) by
hand as it might catch in the stitch plate. Use those threads in the loopers
only.

Chain stitch and OL
1. Upper looper thread (blue).
2. Lower looper thread (red).
3. Right/left-hand OL needle thread (green)
(green tension).
4. Chain looper thread (purple).
5. Chain needle thread (brown)
(yellow tension).
4/3 Thread OL
6. Upper looper thread (blue).
7. Lower looper thread (red).
8. Right-hand needle thread (green).
9. Left-hand needle thread (yellow).
Perfect stitch formation is when both looper threads meet at the fabric edge.
The needle threads form straight stitches for a stretchy and durable seam.
