4/3 Thread OL
1. Upper looper thread (purple).
2. Lower looper thread (red).
3. Right-hand needle thread (green).
4. Left-hand needle thread (beige).
Perfect stitch formation is when both looper threads meet at the fabric
edge. The needle threads form straight stitches for a stretchy and dura-
ble seam.
Thread tension
Thread tension should be properly adjusted to suit the various types of
work.
The ideal tension setting for most fabrics and threads is between 3 and 5.
However this can vary quite considerably when special threads such as
lament, woolly nylon, buttonhole twist (cordonnet), pearl yarn or deco-
rative threads are used. Only use decorative threads in the looper. The
thread must move easily and without resistance through the looper eye.
Innitely variable adjustments can be made from 1 - 9.
Turn the dial downwards for less tension.
Turn the dial upwards for more tension.
