Class 99 & 99K

To Regulate Length of Stitch

The machine is adjustable to make from 6 to 30 stitches per inch, as indicated by the numerals on the stitch indicator plate.

The "red dot" indicator U, Fig. 24, in the slot at the left indicates the stitch setting. To regulate the length of stitch, turn thumb nut V, Fig. 24, on lever away from the stitch indicator plate as far as necessary. Move the lever at V until the "red dot" indicator U is at the desired stitch setting. Then turn thumb nut V inward until it touches indicator plate. The machine is not set to stitch the desired number of stitches per inch in a forward direction.

To Reverse the Direction of Feed

For Back Tacking, raise the lever to the upper end of the indicator plate. The machine will then stitch in a reverse direction, making it easy to fasten the ends of seams.
