2-Thread Subsidiary Looper
Either needle thread may be engaged for 2-thread overlock sewing
1. Open the front cover and the blade cover, 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 to bring the upper looper to its lowest
position.
3. Rotate the subsidiary looper up and to the left (fig. B), insert the
end into the upper looper eye (fig. C).
4. Close the blade cover and the front cover.
Upper and Lower Looper Thread Fine-Tuning
No adjustments are needed when sewing with most fabrics and
threads on your Baby Lock evolve, but certain threads or fabrics may
require minor fine-tuning of the looper delivery system to perfect your
stitches. Increase or decrease the delivery of the looper threads with
the upper and lower looper thread fine-tuning screw. With a screw-
driver (found in accessory kit), turn the fine-tuning screw clockwise to
tighten the looper threads equally. Turn the screw counter-clockwise
to loosen the looper threads equally.
