Frequently Asked Questions
What makes the PFAFF rotary hook system special? The select 4.2 features a high-performance, smooth industrial rotary hook system. Unlike standard oscillating bobbin setups that vibrate back and forth, the rotary hook spins continuously in one direction. This delivers quiet operation, minimal vibration, and smooth high-speed stitching without thread jams.
Can I combine stitches together using the push buttons? Yes. PFAFF's Easy Select system allows you to depress multiple stitch buttons simultaneously. By combining different buttons together, you can customize and discover unique stitch patterns that are not explicitly listed on the front console.
How does the machine maintain piercing force at slow speeds? Traditional mechanical machines lose their punch when you slow down, causing the needle to stall in thick fabrics. The select 4.2 uses electronic motor control to deliver maximum, steady needle penetration force to the needle bar even if you are sewing stitch-by-stitch, keeping you from breaking needles on heavy seams.
