For this exercise, the overlocker will be threaded for a narrow
3-thread rolled hem stitch using the right needle. Thread
with colors to match the color-coded threading path on the
overlocker. Adjust all thread tension settings for a flatlock
stitch as indicated in chart below.
Note: If following instructions in the Mastery book, the
right needle was inserted and threaded, and the left
needle and thread was removed in a previous exercise. If
so, you will skip Steps 1 and 2.
1.
Using the small screwdriver and needle holder tool, loosen
the right needle screw and insert the right needle. Tighten
the needle set screw. Thread the needle.
2.
Remove the left needle thread. Loosen the left needle set
screw and remove the left needle.
3.
Disengage the stitch finger by placing the Rolled Hem
Selection Lever in the "R" position..
4.
Start the machine and run a chain for several inches so that
you have a thread tail to aid in getting the fabric started.
5.
Place the fabric under the presser foot and sew along one
6” edge.
6.
Return stitch length and thread tensions to their normal setting.
7.
Return the Rolled Hem Selection Lever to normal sewing position.
Optional: Thread the Upper Looper
texturized nylon thread
in the upper looper. Loosen the Upper Looper tension slightly
from the settings listed below.

Standard
• The Rolled Hem Selection Lever moves the
stitch finger in and out of position.
•
Push the lever forward (N) for normal sewing
so the stitch can form over it, keeping the
fabric flat.
•
Pull the lever toward you (R) so the fabric
edge can roll when stitching a rolled edge.
