Enhanced Sewing Mechanisms This machine is equipped with advanced mechanisms including a thread spreading mechanism and adjustable needle guard to prevent stitch skipping. The thread clamp mechanism, tension release mechanism, and needle thread draw-out mechanism contribute to improved sewing performance by maintaining uniform thread length and preventing needle thread slip-off.

These options can be easily adjusted using the reverse feed lever stopper, providing versatility in sewing applications.
