Overlock sewing test and fine tuning
After threading select the stitch of your choice (stitch
selection dial) and test sew.
Seam begin, seam end, thread
cutter
Raise the tip of the presser foot with your thumb and position
the fabric just under the foot. Let go of the foot and start to
sew. The fabric will be taken up automatically.
At the end of the seam, continue sewing a 8 cm (3") long
thread chain (1).
Holding the fabric in your left hand, pull the thread chain
over the thread cutter (2).

Fine tuning
Compare your sewing test with the stitch formations on the
waste collector or diagram inside the looper cover.
Example: 4 thread overlock

Needle L thread (yellow)
Needle C thread (green)
Upper looper thread (blue)
Lower looper thread (red)
The upper looper thread lies on the upper side of the fabric
and the lower looper thread lies on the underside of the
fabric. The loops formed by both threads meet exactly on
the edge of the fabric.
Needle C thread forms a stretchy safety seam in the centre of
the stitch. Needle L thread anchors both looper threads.

Stitch formations which are not perfect can be corrected with
fine tuning (3).
To increase the tension, move the fine tuning lever up. To
reduce the tension, move the lever down.
