To Alter the Length of Stitch
Turn the thumb screw inwards (see Fig. 13)
to lengthen the stitch, or turn outwards to
shorten it.
To Change the Pressure on Material
For ordinary family sewing it is seldom nec-
essary to change the pressure on the mate-
rial. If sewing fine silk or flimsy material,
lighten the pressure by giving the thumb
screw (1, Fig. 5) two or three turns upwards.
To increase the pressure, give the thumb
screw a few turns downwards.
To Turn a Corner
Stop the machine when the needle is rising,
but still in the material. Raise the presser
foot and turn the work, using the needle as
a pivot. Then lower the presser foot.
To Sew Flannel or Bias Seams
Use a short stitch and as light a tension as
possible on the needle thread, so that the
stitching will be loose enough to allow the
material to stretch.
