JUKI Tip: Air Thread Sergers VS. Traditional Manual Sergers

In this month’s tip, JUKI National Account Trainer, Alba, demonstrates the difference between an air threading serger and a non-air threading serger. The first serger we’ll showcase is the non-air threading serger, the Mo 114D. This is a non-air thread surger so this is a manually threading serger and the main difference is the way that the machine is threaded.

The other thing is that with a traditional serger, you must follow a specific order and usually it is an upper looper gets threaded first then the lower looper and then the needles in order; so there is a specific order that needs to be followed with this serger. When there is a thread breakage within this serger, it is often recommended that you start rethreading the machine from beginning to end.

Now with the air thread serger, here we’re showcasing the MO-2800, we’re going to show you their differences. Now what the air threading capability is all about, is the mechanism on the inside of the machine and its tubes, allow that jet stream of air to go through. Now in order to activate or start the air thread process we need to flip one lever, shown on video, and it really is as simple as that!

I will be turning the hand wheel towards me and what that does is if you watch this action that tube closes and you hear that click where I am now ready to activate and use the air thread. What is really nice about an air thread serger is it does not matter the order that you thread in! So I am going to go in the opposite order of the one right next to me. Now, I get my thread, I hold it with the tweezers, and I am putting between half an inch and an inch of thread in there. I have 8 to 10 in of loose thread in front of me and that lower looper has been threaded. This is typically the one that takes the most amount of time to thread on a serger and you could see just how easily. Now in order to close the door you will have to lower the lever and that’s usually where I get the call where people will say oh my door isn’t closing and that’s exactly why.

Another feature I was so excited about is the needle threader! I left one needle unthreaded and I’m going to open up the door just to make it easier to see on video, and I’m going to lower my foot and I have a lever that goes right and left. I’m threading my left needle, I have it to that position on video, and I am going to lower my needle threader and I am going to place the thread right in.

There’s a little groove on your needle threader that hugs around your needle and the thread goes right in there. You’ll notice I left it really nice and loopy and when I raise that needle threader up it threads the needle quickly.

Those are some of the differences between a regular serger and an air thread serger! I hope you enjoy these updated features, stay tuned and make sure to hit like and give us your comments!
