Main Features & Creative Benefits

Thread Loopers in Seconds with the Automatic Air Airlock

Say goodbye to complicated overlocker threading procedures. The automatic air threader handles both loopers with a single, quick push. The color-coded threading paths simplify needle setups, and with a maximum sewing speed of up to 1300 stitches per minute, you can construct clean, commercial-quality seams, rolled hems, and decorative finishes in no time.

Bright, Ultra-Illuminated Work Area

Never miss a stitch with a highly illuminated layout powered by 5 bright LEDs. The workspace features 130 mm of clearance right of the needle, allowing you to guide dense home decor projects, heavy canvas, or thick winter outerwear without losing needle visibility. Swap out accessory feet or attach converter parts with ease.

Fine-Tune Edges Instantly with Patented Micro Thread Control

Achieve uniform edge quality on dynamic fabrics without constantly adjusting stitch parameters. The patented Micro Thread Control (mtc) allows you to set the overlock stitch tension once. Even if you alter the cutting width or fabric thickness, the mtc dynamically adapts, saving you time and avoiding edge looping and gathering on delicate silks.

Sleek Free Arm & Wide Extension Table

Tackle a full spectrum of project patterns. The premium slide-on table provides a flat, rounded surface for steady guiding on wide textiles and bulkier quilts. Ready to finish tricky tubular projects? Slide the table off to access the built-in free arm, engineered for guiding sleeve cuffs, narrow pants cuffs, necklines, and kid's apparel easily.

Maintain Sewing Flow with the Free Hand System

Keep both hands planted firmly on your fabric for maximum guiding accuracy. The integrated Free Hand System (FHS) knee lifter lets you temporarily raise or lower the overlock presser foot using a gentle, ergonomic push of your knee. This is perfect for aligning layered patterns, pivoting tight curves, and adjusting thick hems without losing stitch control.
