3. Operating the Machine
Stitch Selection:
The SINGER Heavy Duty 4432 offers 110 stitch applications. Use the large stitch selector dial on the front of the machine to choose your desired stitch pattern. The dial is color-coded to match stitch types for easy identification.

Adjusting Stitch Length and Width:
Customize your stitches using the dedicated dials for length and width. The stitch length dial allows you to adjust the density of your stitches, while the stitch width dial controls the side-to-side movement of the needle, particularly useful for zigzag and decorative stitches.
1-Step Buttonhole:
Creating buttonholes is simplified with the 1-step buttonhole feature. Attach the buttonhole foot, place your button in the designated slot on the foot, and the machine will automatically sew a perfectly sized buttonhole.
