If threads break during sewing
Remove the material and re-thread in the correct
order, Lower looper, Upper looper, left needle
and then the right 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) over the previous stitches.
CAUTION
Do not leave straight pins in the fabric when
sewing as they will damage the needles and
knives.
To sew fine materials
1. Adjust the presser foot pressure to prevent the
material from puckering and to allow sewing of
curves. (See CHAPTER 1 "Adjusting the
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.
To use the stitch finger W
When sewing stretch fabrics, using the included
stitch finger W prevents the fabric from stretching
without adjusting the thread tension.
