Frequently Asked Questions
What is the advantage of the 6 mm stitch width over other mechanical machines? Most standard mechanical entry machines only allow a maximum width of 4 mm or 5 mm. The SMARTER BY PFAFF 140s allows you to widen all your zig-zag, utility, and decorative stitches up to 6 mm, making your custom topstitching and border designs look much bolder and professional.
Can I lower or cover the feed dogs for free-motion sewing? Yes. While the feed dogs do not drop internally, the machine allows you to quickly snap on a darning plate or drop the mechanism manually inside the free arm assembly, giving you freehand control over your fabric for manual repair or darning work.
Is a hard travel cover included in the price? Yes. Unlike standard cloth dust covers, the 140s comes packaged with a rigid, impact-resistant plastic hard cover that encloses the entire body, keeping the thread spindles and tension dials safe when traveling to classes or storing the machine in tight spaces.
