Heavy weight threads can be used through your regular looper thread
paths. Specific techniques may require that the thread bypass the
thread port for the thread pull to be loosened. Start with the machine
threaded with regular serger thread.
1. Open front cover and raise the presser foot.
2. Just above the threading port, clip the looper thread to be replaced.
Pull the thread out of the upper guides and remove the cone.
3. Place the specialty thread on the spool pin. Thread it into the upper
guides and clip it a couple of inches beyond the base plate (fig. A).
4. With machine in the serging position, use the tweezers to pull the
existing looper thread out of tube extending from the threading mech-
anism (fig. B). Leave the thread in the looper arm.
5. Tie the specialty thread onto the regular thread with an overhand knot
(fig. C). Pull on the regular thread from the looper eye until the spe-
cialty thread comes through the looper eye (fig. D).
6. Place upper looper thread under the foot and to the left: clip lower
looper thread at the base plate.
If the thread is heavy and the overhand knot (step #5) is too large for the
looper tube, follow directions (#1 thru #7 on page 79) to make a thread
cradle. Then:
1.
Engage the threading lever to the serging position.
2. While holding the loose ends of the thread cradle with one hand, use
the tweezers to pull the cradle loop out of the tube extending from the
threading mechanism with the other hand.
3. Insert 2 inch(5cm) of your decorative thread into the cradle loop. Pull
on the loose ends of the thread cradle from the looper eye until the
specialty thread comes through the looper eye.
When bypassing the threading port, thread will be visible from the
guide to the looper tube (fig. E). Close the blade cover and front cover
before continuing to sew.
