Controls on the Brewer
Without the manual, we are not exactly sure as to the proper operation of all the controls. The left-most large dial is a pattern selector. The top right knob controls zig-zag width while a lever on the same axis selects needle position right, middle, and left as seen in the small round window. A smaller white knob controls stitch length.
The lower knob is used to form button holes. Making a button hole is a 4-step process by rotating the dial to form each of the four sides of the buttonhole.
Missing on our machine is a button which can be depressed to control sewing in reverse.
