2-Thread Overlock
Converting from 3-Thread to 2-Thread Overlock
The 2-thread function provides an economical and less bulky means of overedging all fabrics.
When joining two fabrics together with 2-thread, the seam it forms is not standard overlock seam but
a flatlock seam. 2-thread rolled edge creates a delicate finish on fine wovens and smooth silkies.
When sewn with specialty threads, 2-thread serging makes decorative seams and edges for active-
wear, children's clothing, ruffles and hemlines.
Either needle thread may be engaged for 2-thread
serging.
1. Open the front cover and cut the upper looper
thread just above the threading port. (fig.A) Raise
the presser foot and pull out the clipped thread from
under the foot. Remove the upper looper thread
from the machine.
2. Rotate the handwheel counterclockwise to bring the
needle clamp to its highest position.
3. Slide the subsidiary looper to the right direction and
swing it counterclockwise to the left. (fig. B)
Close the front cover.
4. Close the front cover, decrease the needle
tension for 2-thread serging. (see chart on the in-
side back cover)
The needle and lower looper threads should over-
cast evenly on the cut edge of the fabric. Sew a
test sample. Make adjustments if needed. Refer to
diagrams.
*The cutting blade cover has been removed in pho-
tos B and C for a clear view. You do not need to
remove the cutting blade cover.
