Thread breakage during sewing
Sew off immediately at an angle and remove the work. Re-thread.
If the upper or lower looper thread breaks during sewing, re-threading is
necessary. Remove both the broken and unbroken looper threads. Then,
set the threading lever to the threading side to carry out threading of the
upper and lower loopers.
First thread the looper and then the needles.
Start sewing again about 2 - 3 cm in front of the break.
2-3 cm
Unpicking seams
Looper thread can be easily undone by cutting the right and left needle
threads with a commercially available seam ripper at several points of the
finished seam and removing them.
Sewing in tape
The standard presser foot is equipped with a tape guide.
A tape can be sewn into the shoulder or side seams of gar-
ments made from knits or stretch fabrics to prevent stretch-
ing.
