- Place four spools of thread on the thread stand.
- Guide each thread through its respective thread guide on the stand.
- Follow the color-coded or numbered threading path indicated on the machine for each looper and needle.
- Ensure threads are seated correctly in tension discs.
- Thread the needles last.
2. Adjusting Tension
The machine features individual tension dials for each of the four threads. Adjust these dials to achieve balanced stitches. Typically, a balanced stitch will have the needle threads meeting at the edge of the fabric, and the looper threads forming a smooth, even seam.
