1-7. Changing threads
The machine comes threaded with overlock
thread. To change thread follow the easy
threading as explained on page 8~10 or to tie
on:
1. Cut the thread in use near the thread spool
(behind the telescopic thread stand). Place
the new thread spool on the spindle and tie
the thread ends together.
2. Raise the presser foot with the presser foot
lift to release the thread tension, and the
knot can easily pass through the thread ten-
sion discs.
3. Pull out the looper thread until the thread
knot comes about 10 cm (3” to 4”) behind the
presser foot.
4. When changing the needle thread, cut the
thread knot before it reaches the eye of the
needle to avoid bending the needle.
Thread net
In some cases cover the spool with the net
to prevent threads from slipping off the spool.
Slide on the net so that it covers the spool
entirely.
Spool holder
When using standard thread spools, place the
spool holders as shown to hold spool in place.
And prevent thread from getting caught on
edge of spool.

1-11. Adjusting the stitch width / cutting
width
The distance between the needle and the outer
edge of the fabric is called stitch width/cutting
width.
• The cutting width can be set between 5-7 mm
depending on the type of fabric.
• Normal stitch width/cutting width is 5.5 mm,
which corresponds to “N” on the dial.
• Turn dial ato set the cutting width.
Note: There is an index mark on the machine.
1. Turn dial ato set the cutting width.
2. If thread loops are formed off the edge of the
fabric, turn the dial to a higher number to cut
less fabric away.
3. If the fabric puckers within the overlock seam,
turn the dial to a lower number to cut more
fabric away.
When you experience loops off the edge of the
fabric, slide the stitch Ànger toward you for Àne
tune width adjustment.
To adjust, move the stitch Ànger lever toward
you from “N” position to the mark —. There are
two Àne tune settings.
After adjusting, test your stitch.
1-12. Stitch length
Normal stitch length is 2.5 mm, which
corresponds to “N” on the stitch length dial.
You may change the stitch length between 0.8
(rolled edge) and 5 mm.
