Thank you so much 🥰 , i managed to fix mine. God bless you.

This was VERY informative!!

Thank you, Thank you.

I am someone who does this work professionally. As the video describes the distances between the loopers and needles is critical. However, the advice given does not relate to any timing adjustments and may prove unreliable for different scenarios. Adjusting the lower looper from the point shown will change the radius of its arc. This alters the geometry of how the needles and loopers can interact and potentially builds a situation where other settings can't be comfortably positioned in relation to the looper. A 'safer' location to adjust from would be at the base of the lower looper support where the piece connects to the rotating shaft. This position allows movement of both distance to the needles and timing, without changing the geometry. The upper looper adjustment shown can be an ideal way to correct some issues. However, forcing the position with pliers may wear down the grip holding the upper looper in place. A better approach would be to remove the upper looper converter mount at the top of the upper looper shaft and loosen the screw holding the upper looper in place. Care must be taken on a machine like the one shown as the looper's inserted depth is also important. Using needles one size larger can be an easy method for temporarily working around issues arising from improper distances. A common failure that can appear as a timing issue is a slipped upper looper projection. This can mean the upper looper collides with other parts or doesn't pass over the needles correctly. The adjustment is from the base of the upper looper arm where it connects to the rotating shaft.

Thank you. U helped a lot. I have q empisal server and I used those techniques u showed. And it's up and stunning smoothly

Thank you...very helpful.

Thanks this was helpful ❤

Thanks so much I needed this now I think I can fix the problem. It's the clearest and best info so far

Thank you so much. Although I have a different type of serger this was the most helpful and my machine is now working again. Had the upper looper in wrong position. That's done. Now my machine is snagging the fabric although I changed the needle. Maybe it need some fine tuning.

Wonderful video. Very informative

Any ideas on how to correct a skipped stitch? Top left needle is not catching upper looper thread. In slow motion it looks like the top left needle thread is catching on upper looper. I have Juki MO-134

Mine keeps hitting each other since the upper looper is at front the lower looper 😂 now I know why it doesn't work.

You put this 9 years ago but watching it this morning in 2023 saved my butt a lot of money. Your awesome!! Thank you so much.

Thank you very much!👍

I got an s4d empisal the loopers dnt pick up please help

Thank you!

thank you!

Hello, I have a problem. I bought a new owerlok machine. It broke down after two months. The service center said that it was my fault because I used the wrong lubricating oil. I don't agree with that because I used sewing machine oil to lubricate it. I realized that the problem was something else. That's why I searched KZfaq for videos that could help me. That's how I came across your video. The problem with my owerlok is that the lower looper on the way to the top position for some reason bypasses the upper loop and comes in front of the upper loop and naturally blocks or gets stuck. The correct course is that the lower looper move behind the upper one. I hope you understand what I mean. If you could help me solve this problem, I would be very grateful.

Thank you so much, please post this video on social media and everywhere you can, so many more can repair their sergers without throwing away their old ones. Years later most people haven’t seen this and still have the same problems. Greetings from Germany 🇩🇪 !

Just got it fix by myself 💟

Hey Jasmine, just want to say thanks to the most high for letting u post this video because u have saved me $3000 to get it fixed thats how much or more in Jamaica Yahuah barak u and your family shalam.

Thank you so much, this helped me so much!!!!

Thank you so much for this! ❤️

Thank you! I found your simple explanation of where the lower and upper loopers need to be at the lowest and highest point of the needles to be exactly the information I needed to get the timing on my Juki BabyLock Proline BL4-838D working. (I put in the model number for anyone else wanting to time this model - although your explanation works for other models too.)

Thank you soooooo much!!!!

Thanks so much this video has really helped me alot

BRILLIANT

Thank you it was very helpful :)

Thanks for taking the time to make this video, unfortunately I couldn't see what your threads were doing due to the poor contrast of lighting, it was like watching a silhouette somewhat.

This was so helpful! I really appreciate the clear explanation. I already spent $100 to have my $200 serger fixed once, issue was timing was off, makes no sense to spend that kind of money again. Thank you for helping me help myself! And you know what? 8 years after you posted this video there still aren’t good videos about loopers and timing…yours is the best I’ve seen!

Chile..... omg and we have the exact same serger too !! Shout out to you & God!!

Pls help, my lower lopper isn't moving at all

Good excellent helpful video. Thx

Thank you! I appreciate you sharing what you learned. Have a great day!!

serger not stitching

Sadly the screws at mine are fixed very tight. I can not move them at all and loosen them. Please does anyone know how I could loosen the screws? How tight do they have to be fixed after the adjustment? I would be very happy if someone would have an idea to help me solve my problem. I already had it at a professional for repair and he could not fix it. So I did spend a lot of money for nothing. Thanks a lot for posting this! In your video I can see it better than in my old baby lock.

Thank you so much for this awesome video. I was able to get my timing fixed and my 1988 Huskylock 530 back in operation! You are the best.

Hi Thank you - I'm going to look at the loopers now. My stitches are ok for about 4-6 inches then alternate from very loopy at the back to ok and keeps reoccurring. Am I correct in thinking this could be a timing issue ? Thank you

Can you guide me how to fix my over lock machine . it is making the holes at stitching line and also breaking the threads again and again. Please tell me how to fix that

Mine is not picking up the left thread in the needles

Until today I had never considered a timing issue.. thank you.

Thank you for making it direct and simple.

I just found you! 6 years later! Thank you, thank you, thank you for this!

thank you so much for your tutorial. Ive never fixed timing a day in my life. My jenome went crazy off a simple thread lol. it was making a baaaadddddd noise. At a critical time yesterday i usally drop off at shop pay 90-100. I was no no, lord help me tooo much money. i jump on your youtube followed what you said, PERFECT stitch in less than hour. thank you thank you and blesssssssings

Loved your video helped a lot, but what my problem is that the upper looper is unthreading itself, I have a Bernini 800 dl please help thanks

What surprised me most was that the upper looper passes in front of the needles, which pass in front of the lower looper, which passes in front of the upper looper, which...

Thank you so much Jasmine, your video has been so very helpful to me, Iam so grateful. You are a genius ! From Yorkshire, England

My overlock machine the hand wheel don't move the needles don't sewing.??

This is really helpful, thank you!

Hey Jasmine, just wanted to say thank you for posting this video. It enabled me to diagnose my looper issues. When I started digging into it, I found there are actually two adjustment screws that give you more adjustment for the timing. On the upper looper inside the post it’s mounted to, is a very small Allen screw. If you loosen that screw you’re able to adjust the position of the upper looper. For the lower Looper, behind the thread guide is another small Allen screw. Loosen the thread guide and drop it out-of-the-way and you’ll see the small Allen screw. you’ll notice as you loosen or tighten it, the angle of the lower looper moves in and out. I’d never have found those screws without your video, so thanks again!
