Thread breakage during sewing
Thread breakage during sewing
1. Turn the workpiece at a right angle direction and stop sewing
immediately. Then remove the workpiece.
2. Rethread.
* If the lower looper thread is broken, cut the both needle threads
off at the needle. Then remove the threads. Thread the lower
looper and then the needles.
* If the upper looper thread is broken, remove the looper to lowest
position. Then thread the looper thread.
Bring the thread through under the presser foot and pull about
10 cm of the thread out behind the presser foot.
3. Raise the presser foot, and place the workpiece under the press-
er foot. Sew about 2 to 3 cm over the seam which has already
been sewn before the thread breakage.
