Your Zig-Zag Sewing Machine, by virtue of its design, permits
you to do zig-zag sewing and numerous other kinds of worK
requiring a similar stitch. The controls for the zig-zag stitch
are located on the arm of the machine, as may be seen on
Fig. 23, Notice lever "B” which adjusts the width of the zig­
zag seam. For ordinary straight sewing this lever must be set
to the left of marking 0 in the indicator. By moving this
lever gradually to the right toward 5 the machine will sew a
zig-zag seam of increasing width, depending on the position of
the lever. For the purpose of reverting to a previously used
width of zig-zag stitch after having done some straight sewing, ^
or for special types of work such as sewing buttons or making tacks, indicator A will be found useful. Thi^s
indicator serves as a stop for dial "B”, To set indicator "A”, loosen lockscrew "D”, turning it to the left.
You then will be able to turn same sideways which, at the same time, moves indicator TA” to the desired marking.
Tighten lockscrew "D” by turn-ing it to the right. The lockscrew also tightens slide "C”. The purpose of this
slide is to make possible a second setting of zig-zag width. Thus, when you want to alternate between a narrow
and a wide zig-zag stitch, you use both indicator "A” and slide “Ch For example, set indicator “A” at marking
4 and slide "C at marking 1, tightening the lock screw. This will assure you of being able to always revert
to the same narrow and wide zig-zag seams. You will find this feature especially convenient when making
buttonholes. Refer to chapter on Buttonhole Sewing .
