If threads break during sewing
Remove the material and re-thread in the correct
order, Lower looper, Upper looper, right needle and
then the left needle (to re-thread, see CHAPTER
3 "Threading"). Replace the material under the
presser foot and sew 3-5 cm (1-1/8 to 2 inches)

sewing as they will damage the needles and
knives.

material from puckering and to allow sewing

presser foot pressure".)
2. Loosen the thread tension, but remember that if
the tension is too loose, the thread may break
and stitches may be skipped.
