Baby Lock Ovation (BLES8) Instruction and Reference Guide - Manual (Page 79)

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 the front and the cutting blade covers 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. Thread the specialty thread into the Bypassing thread guide
located on the left side of the threading ports. (fig. B)
5. With machine in the serging position, use the tweezers to
pull the existing looper thread out of tube extending from the
threading mechanism. (fig. C) Leave the thread in the
looper arm.
6. Tie the specialty thread onto the regular thread with an
overhand knot. (fig. D) Pull on the regular thread from the
looper eye until the specialty thread comes through the
looper eye. (fig. E)
7. 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 #6) is too
large for the looper tube, follow Steps 1 through 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 inches (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. F) Close the cutting
blade cover and front cover before continuing to sew.
Note: When necessary to use Bypassing thread guides with
thread cradle make sure threads are not twisted and / or
tangled leading from the guides.
