12. Regulating the Stitch Width
The stitch width is regulated by turning knob G which is located in the middie of the
machine arm (Fig. 20). The numerals on the zigzag scale indicate the stitch width in
millimeters.
When pointer Z is set on zero, the machine sews straight.
When you turn knob G to the left, the stitch width increases gradually and the machine
makes the zigzag stitch.
With the zigzag knob at the extreme left of its scale, the machine will make stitches
about 3/16" or V4" (4.5 or 6.0 mm) wide, depending on the machine model.
There is a small lug on the underside of pointer Z which engages in a notch of slide S.
Screw B serves to lock this slide in position.
If you set the zigzag knob on 2 and tighten screw B, for instance, the stitch width is
fixed and will not be disturbed by the vibrations of the machine when sewing. In spite of
this, knob G can be jerked to zero when a few straight stitches have to be made in back-
tacking the end of a seam. By the same token, knob G can be jerked to the left for a
wider zigzag stitch. Returned to the middle of the zigzag scale, pointer Z will again en
gage in notch R of slide S so that the previous stitch width setting will be restored
automatically.
Switching from straight to zigzag stitching as well as changing the stitch length and the
stitch width can be done while sewing.
