Thanks to the practical RevolutionAirTM threading system, the threads are threaded into the hook and the eye of the needle at the push of a button with a blast of air. The automatic yarn feed system eliminates the annoying task of setting the correct yarn tension. This allows you to process different materials and yarns without any problems. The extra high foot stroke offers you even more freedom in processing thick or several layers of fabric. In addition, the long-life LED lighting ensures a perfect view of your project.
