Thread broke on bottom looper the first time out of box i had to try and thread and the tension was still tight The bottom threads were not stiching


I'm going to assume here you're talking about a serger. Unthread the lower looper and the eyes of the needle. Set the lower looper tension to 0. Rethread the lower looper, then the needle eyes. Then reset the lower looper tension (try about half a number lower) and see if it chains. If it won't chain, try replacing the needles.

Thread breaking at loupers on overlock machine singer


If it's the lower looper thread breaking, the cure is to unthread the eye of the needle(s), rethread the lower looper, then rethread the needles. Sergers have very specific internal crossings that are easiest to do if the various parts are threaded in a particular order. Typically, you thread the upper looper, then lower looper, then the needles. If you try to deviate from that without knowing exactly what you're doing, it tends not to work well.

In general, most serger troubles, especially for beginners, trace to minor misthreadings. It's easier, in my opinion, to rethread the entire machine from scratch than look for the minor error that's catching you up. And you learn the threading pattern well as a special bonus. <g>
If it's not cureable by rethreading a couple of times from scratch, the next thing to do is put in new needles, right way around, and rethread again.

Can't thread a consew 694ex


Typically a serger is threaded... upper looper(s) Lower looper(s) Needles from right to left. Anything else will cause you problems. If you break a thread... remove all other threads and begin again at the upper loopers.

Serger - my needles break, never happenned before, and over travels on left upper looper


Make sure, Joe, that your needles are pushed up into needle bar shaft a's high a's they will go. Although same length, the left needle will appear higher than the one on right side when properly seated and tighten clamp screw securely. Check Lower Looper for proper threading--thread delivery eye of lower looper to far left "hidden" from sight. Use looper tweezers and it helps threading it. The thread then gets pulled to right side and goes front to back of that hole in front of you on lower looper. Follow threading guide on the cover door to right of your serger. Hope this helps.

Need instructions on threading 4-434 overlock serger


Open up the front cover. There should be a diagram right there, and you want to thread your serger step-by-step per the color-coded diagram so that the needle is in time with the movement of the loopers. If you randomly go about threading it instead of in sequence, the threads will collide and you will create a jam. The usual threading order: Upper Looper, Lower Looper, Left Needle, then Right Needle. Do you have long serger tweezers? Do you have a Looper Threader? If not, these are great tools to assist you as the Lower Looper is threaded right to left- an eye all the way to the far left, so it helps to have the tweezers and Looper Threader to maneuver in this very tight area. Many new serger users don't realize that other eye is "hiding" and miss threading it! Hopefully, you have a manual with additional pictures to help guide you. If you need a manual, try allsewingparts.com and perhaps they have one specific to your serger. Note: When you insert your needles (make sure they are #11 and #14 specific for your particular machine), the left needle will be the same size as right needle, but will APPEAR higher once both are pushed up into each of their respective needle shafts. Note: Hold onto needles or put a piece of fabric under the area when changing them/replacing them because they can easily fall out causing damage to your machine. Hope this helps. Jimmy

Why does the 4th thread keeps breaking on my serger? I've re-threadedi it a dozen times carefully following the diagram. What am I doing wrong?


Most likely it is either your tension on thay thread being too high, or the needle is too big for the project you are working. Lower that tension, use the next size up needle, and thay should fix it. Also, I STRONGLY suggest only using maxi-locks thread. They are more expensive than other serger threads, but they are always half-price at hancock... Any other thread I have tried using causes breakage, especially on the the lower looper (the 4th thread). Although, of you keep the tension low-below 3 or so, you should be ok. If these tips don't help, I would also check your cutting width, if your machine has an adjustable one. If it is leaving too much gabric to the right of the needles, out is conceivable that this is putting too much pressure on the threads. Let me know if this helps!

I have been chaging my serger to overlock for the purpose ofdoing rolled overedge. Rethreaded numerous times, have read the instructions many, many times, setting tensions, etc. I cannot get it to even...


How frustrating, I've tried to find a manual on this model so I can see how you make the change to the thread finger on the throad but couldn't see one. So, I'll go through the set up for 3 thread rolled hem on mine, it probably won't be identical but it might help.

First, remove thread from left needle and remove the left needle from the holder leaving just the right hand needle in place. Most sergers have two seperate needle screws so this can be done but as you mentioned, recheck again that the right needle is right up into the housing as high as it will go. I presume you are using a fresh smaller size needle, especially if this is on a fine or lightweight woven like organza, I'd put in a size 70. If a mid weight then size 80.

Now there should be a thread finger on the foot you change with your screwdriver. Or a little switch you flick so that the throat plate is a different shape to form the narrow seam. Your manual should have this step.

Now if you have some, put wooly overlock thread into your top looper, I cut the thread about 10 inches above the tension dial, put the new spool on, knot it to the existing thread tail, turn tension to zero and pull it through and through the looper eye.

At this point, you should have the two looper threads loose, lift the pressure foot and pull these two threads under the foot and out the back. Turn tension back to about 3 on top looper and tighten up lower looper to 5 or 6 and leave needle at 5.

Adjust blade to cut quite wide, ie wind it to the right side. Now thread the right needle and pull this thread out the back too. Lower the pressure foot, introduce a piece of fabric in under the foot, press the pedal and start trimming and chaining off.

You should have a chain stitch happening now - if not, recheck your threading, particularly the needle, sometimes the thread looks like its in the needle eye but is hooking around the looper. If you still can't get any joy, then it is possible that the timing is just slightly out and this is affecting this stitch. You could try setting up for a normal three thread seam and see if this chains okay.

If you are getting a chain happening now, then adjust down the stitch length to make it denser so it is covering the fabric and check the underside, adjusting top and bottom looper tensions so the thread is enclosing the fabric end rolling to the underside and covering any little fibres.

I hope this is of some help - however, if it still isn't giving you a chain, it could be the timing is out in which case, unfortunately service time.

Instructions for threading Baby lock eclipse BLE1LX for 2 thread sergering


I have just learned this :)
Either needle thread may be engaged for 2-thread serging.
1. Open the front cover and cutting blade cover, cut the upper looper thread just above the threading guide ( this is plate that has two holes for the threads) Raise the presser foot and pull out the clipped thread from under the foot. Remove upper thread from the machine (or you can leave the cone thread on, it doesn't matter).
2. Rotate the handwheel to bring the upper looper to its lowest position.
3. Rotate the subsidiary looper up and to the left, then slip the end into the upper looper thread eye from backside.(this sounds complicated, yes? but it is very simple : the looper has a counter part that is spring-locked to move from left to right and right to left. This is the little claw-looking part of the looper that when in the postion to serg with four threads is to the right side of the looper. It looks like a scorpion's tale. If you can't figure which part it is, use your finger to probe the looper and you'll feel it give a little. This part needs to be moved to the left - it will not slide over, but swing up and over and down, like an arch. Then, where the thread comes out of the looper is where you want the little claw-like part to hook into.)
4. Close the covers. Decrease the needel tension - this depends on what the stitch length is. Stitch length: 2-3, stitch width: 3.0 = L needle n/a, R needle 1; upper looper n/a, lower looper 5
stitch length: 2-3, stitch width: 5.0 = L needle 0, R needle n/a, upper looper n/a, lower looper 3.5

Those are for a flatlock stitch - for a 2-thread rolled edge :
Stitch length: 0.5, stitch width: M = L needle n/a, R needle 4.5, upper looper n/a, lower looper 3.5
Stitch lenght: 1.0, stitch width: M = L needle n/a, R needle 4, upper lopper n/a, lower looper 3.0

Sounds like the timing is a little out.

If you remove the needle plate and turn the handwheel manually watch for the lower looper as it swings behind the Left needle....the needles ought to rise by only about 2mm before the looper passes......the looper must pass the needle above the eye to catch the thread, and be so close as to be barely touching the rear of the needles......if the left needle thread is not picked up, it may be the timing, or the distance between needle and looper.

For the uninitiated, there are a myriad of variables in correctly timing an overlocker (serger), and without the manual to refer to the correct parameters, you will rapidly descend down a road of despair....if you move a looper to advance or ****** the timing, you risk looper collision and a broken looper is almost as much as a service, so my advice is do the test to see if the timing is the likely culprit, and if so, take the opportunity to give the old girl a treat.

If you need to save for a while to do it, just use the 3 thread option for the time being.
