Juki MO-6714S Industrial 4-Thread Serger Review

If you are looking for an overlock sewing machine of excellent quality and from a serious and reliable brand, the Juki MO-6714S industrial machine is what you need. This 2-needle, 4-thread, industrial overlock sewing machine allows you to work faster thanks to its powerful motor, which is also responsible for very quickly sewing: 7,000 stitches per minute.

This sewing machine is great for people who work with both light and medium fabrics. Its frame is made of metal, so it’s solid enough to handle these types of materials without any problem. The Juki MO-6714S also has a decent table that allows you to sew larger pieces without worrying about the fabric getting stuck or uneven stitches, and this sewing machine locks your fabric in place while working on it.

The design of the Juki MO-6714S industrial overlock sewing machine will make your workplace more organized. Another thing we really liked about this model was its differential feed capabilities, which make this overlock sewing machine versatile enough to handle a wide range of fabric types, from stiff to stretchy.

The Juki MO-6714S is one of our favorite machines because it’s very easy to use due to its modern design and layout.

This item is sold as a complete unit, including the machine head, table, stand, motor, sewing light, drawer, and all necessary components installed and ready to sew.

This semi-automatic machine has 2 needles and works with up to 4 different threads for a better finish and safety. You can see the type of stitches on its front panel, and you can make all the necessary adjustments, from the length to the width of the stitches that go from 0.8 to 4 mm and 3.2 to 4.8 mm, respectively.

This machine is intended solely for overlock stitching of light to medium weight fabrics. It is designed to perform at high speed with excellent reliability and consistency.

But because this is industrial equipment, minor blemishes and scratches on the table and legs may occur during the production process, but these do not indicate any defect or deficiency in the operation of the unit.

Features of Juki MO-6714S Overlock

Servo Motor

The servo motor allows precise control regarding the angular position, acceleration, and speed, capabilities that a normal serger machine’s motor does not have. On the other hand, this type of motor usually offers a quieter operation, weighs much less, and uses less energy than a common motor would occupy in a normal sewing machine. It is known that it is possible to use up to 90% less energy.

It has the ability to operate in reverse when needed; you just have to press a button for that to happen. As mentioned initially, this type of motor helps the stitches be made quickly or slowly, as needed.

Adjustable Differential Feed

The differential feed function of the MO-6714S, which the external control connects to the internal, is used to control the feed dogs, the fabric you’re using, and feed ratio settings.

The differential ratio for gathering can be adjusted between 1:2 mm and 1:4 mm, and for stretching, the adjustable ratio varies between 1:0.7 mm to 1:0.6 mm.

The machine’s wide range of settings and blinding speed allow you to stitch perfect seams on any project.

And the instruction manual almost always includes a guide with the settings indicated for each type of fabric, although you will not need a guide over time.

Dual Thread Tension Controls

For perfect stitches, it is possible to adjust the dual thread tension thanks to its easy-to-use control. You must operate it manually but if you have doubts, just check its user manual. You can get uniform stitches of the length you want; you just have to use the same quality and type of thread for this operation.

Backlatch Function

When it is in automatic mode, this function is used to close the sleeves and sides of shirts, sweatshirts, and similar clothing, but you can also deactivate it when you see fit. You just have to press a button.

But this 2-needles, 4-thread overlock machine can be used in sewing projects that do not need a backlatching feature.


Unfortunately, this industrial overlock machine only offers a 90-day warranty for its users. It is very small but still has an excellent reputation for performance.

The Verdict: Is Juki MO-6714S Worth Buying?

The 6714S is an industrial machine with high performance. This machine offers very good features and is highly valued by users for the quality of its stitches and its high working speed.

It is an expensive machine, but it is worth it since it includes many accessories, especially if you are an expert in sewing and looking for a good quality industrial machine.

This sewing machine is perfect for people who work with both light and medium fabrics because it has a metal frame that’s strong enough to handle these different types of materials. It also has an excellent table, so you don’t have to worry about having problems when working on large projects.
