Note
Always have the upper cutter in the cutting
position when sewing, because this
machinemusttrimo󰀨anyexcessfabric
to form the stitch over the fabric edge. An
exception to this is when sewing decorative
atlockseams.Thentheuppercutter

Attach the 2–thread overlock converter
Note
2-thread overlock stitches are sewn using
one needle thread and the lower looper
thread. Before sewing, the two-thread
converter must be attached to the upper
looper, so the machine will sew with only
two threads.
Open the front cover.
Bring the upper looper to its higher position
by turning the hand wheel toward you.

Getting ready to sew
vWhat needle and thread to use with di󰀨erent fabrics
vGeneral threading information
A color coded diagram is located inside the
frontcoverforquickreference(seeillustration
to the right). Always start threading the
loopers and then the needles from left to right
(followtheorderlistedbelow).
1. Upper looper - Red
2. Lower looper - Yellow
3. Left needle - Purple
4. Right needle - Green
Note
Always raise the presser foot before
threading.
Important:
If the threads break during sewing, re-thread
all thread paths in the order listed below.
1. Unthreadtheneedle(s)
2. Unthread upper and lower looper
3. Thread the upper looper
4. Thread the lower looper
5. Threadtheneedle(s)fromlefttoright
See the table below for recommendations on
whatneedlesandthreadtousefordi󰀨erent
fabric weights.
Tip:
Your new machine is threaded to sew a
4-thread overlock. Tie your own threads
to these threads and carefully pull them
through the machine, to easily thread your new
overlockmachinethersttime.
