Fabrics NOT To Use with The 623 Serger

The following fabrics are not recommended to be stitched in your 623 Sewing Machine. While some of these fabrics may work for a short time, they can void your warranty, cause motor failure, and prematurely dull your blades. As a general rule, stick to light or medium-weight fabrics. 

• Canvas - Hevy and may shorten the life of your 623's motor (over time). 
• Leather - Doesn't work with a serger due to thickness and lack of pliability.
• Thick Wool - Thick wool is dense and has multiple layers, making it unsuitable for this sewing machine.

What is a Serger?

A serger is a specialized sewing machine that not only sews fabrics but also trims the seam allowance and finishes the edge with an overlock stitch–all in one pass. This combination of functions creates a durable seam that resists fraying and gives a professional look.

Advantages of Using a Serger

• Overlocking stitch: Unlike the stretch stitches on a regular home sewing machine, the overlock stitch on a serger encloses the raw edge, preventing fraying over time.
• Speed: Sergers like the Juki MO-623 are known for their speed. This one operates at 1,500 stitches per minute, perfect for projects with long seams or edges to finish.
• Efficiency: Overlock machines create seams, trim excess fabric, and finish the edge all in one pass, so they are extremely efficient.
• Flexibility: The Juki MO-623 overlock machine not only simplifies the sewing production process but can also sew many different types of fabric.

While industrial sewing machines are often specialized for one function, like straight stitching, the Juki MO-623 overlock serger does multiple tasks in one. Affordable and priced for home and professional sewers.

Why Our Customers Love The JUKI 623

As an authorized dealer of Juki, we sell sewers of all skill levels the Juki MO-623 as a top lightweight sewing machine. From its user-friendly design to its powerful performance, this machine is designed to give professional results with minimal hassle.

Easy to Operate

The Juki MO-623 is easy to operate and a great starter for home and professional sewers. Color-coded thread guides simply match the threads from the stand into the machine. There is no need to change presser feet or settings for fast seaming and built-in rolled hems.

Compact and Affordable

Goldstartool has a large selection o Juki serger machines, like the industrial model MO-6843S, which can do six threads at once. However, the MO-623 is smaller, easier to operate, and only uses three threads. For hundreds less than the six-thread industrial model, the MO-623 is a more compact and affordable model for home and shop sewers.

Powerful and Quiet Motor

Despite being a powerful overlock machine, the Juki MO-623 is quiet. Its low-volume operation and fast stitching allow you to sew for hours and complete large projects.

Threading the Serger

Threading the MO-623 may look intimidating, but it’s actually quite straightforward. The color-coded thread guides tell you which thread goes where—needle, upper, and lower. Starting at the thread stand, follow the blue, red, and green dots for the upper, lower, and needle thread. The MO-623 holds three cones, the larger of which will have about 3,000 yards of thread.

If you’ve threaded the machine incorrectly, the best course of action is to remove all the threads and start over.

What Can I Do with the MO-623 That My Regular Machine Can’t?

Seams are easy and fast; you sew the seam, trim the seam allowance, and overcast the edge all at once, and you're done with it. Your seam won’t unravel as it might with a standard domestic or industrial sewing machine.

You can also overcast a raw edge of the fabric before hemming or other stitching work. Adjust the machine for this overcast type (see the instruction manual), and the knife trims a neat, clean edge. Then, finish the hem on your regular sewing machine.

User Tips 

Remember that the Juki MO-623, like any serger, only sews in one direction–it doesn’t backstitch like a regular sewing machine. The overlock stitch sews, trims, and finishes seams in one pass, but you can disengage the knives if you don’t want to trim your seams. It’s best to start and stop each seam with a short chain of stitches to secure the edges.
