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) 
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 fi ne 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.
