The Juki MO-654DE serger is a 2-needle, 2/3/4-thread overlock machine with differential feed and micro safety switch.

The Juki MO645DE is a great serger that many have found to be an amazing machine. Part of the Pearl series, this model allows the use of 2, 3 or 4 threads and comes with a micro safety-switch. Construct garments like lingerie, swimwear or athletic-wear with simple ease, using any thread of your choice.

The Juki MO654DE serger is capable of working with the latest fabrics and almost any decorative thread, making it a versatile addition to your sewing room. For easy threading, simply follow the color-coded guides along the body of the machine.

To make seamwork easier for beginners or experienced alike, Juki has included a built-in guide for seams that you can follow. To cut fabric consistently and smoothly while sewing, the lower knife and upper knife combo works in tandem through a dedicated drive.

If rolled hems are your weakness, the Juki MO645DE is here to help. Rolled hems are made much easier – just flip a switch and go!

For increased versatility on your project, the stitch length can be adjusted with the provided dial. You can adjust tension similarly with the provided tension dial (1-rotation).

The presser feet snap on and off to make switching them out easier.
