First, I'm a beginning serger. Things were going along smoothly until I had to disengage the knife then put it back. Every time I think I have everything figured out, rethreaded etc I go to serger and it jams. What am I doing WRONG?????

Hvae you tried running the serger without fabric? If not, try it. Try disengaging the knife and running it. If it still jams something is probably wrong in the threading. If it runs ok make sure the knife is back in the right spot. It's really easy to put the knife back in place and think it's right and it's just a tiny bit off and everything goes wrong.

What type of serger do you have? That will help with more advice as my answers are sort of generic to sergers in general.

I agree with simplystitches, try running it with the knife disengaged. If it only jams when the knife is engaged then chances are it is not aligned quite right, stuff like that happens and usually isn't fatal. Another thing I would try is replace both needles. It is possible they were slightly bent in the beginning.

When you rethread, make sure there are no little pieces of fuzz built up in the thread path, those can often cause ugly things to happen.

Thank you for the posts! I got the knife situation worked out. Rethreaded twice. Now the needles are breaking! Urggg!!! Banging my head against the wall!

Oh it's a singer stylist II! Thanks again!

What are you sewing? That's an important part of this equation.
Needles breaking could be another ball game.

My best advise right now - is shut it down - walk away - yes I know that's hard but your frustration is also not helping you. So go have a coffee or even better wine

Are you threading in the correct order, completely from the beginning, and making sure the threads are seatin the tension disks ed correctly? Except for Babylocks, threading order is crucial on sergers.

Too funny! That is exactly what I did! Took the kids to the movies...but did I spend the whole time thinking of what the heck I'm doing wrong and being discouraged...sure did

I have the order marked on my machine so I am pretty certain it is correct. I'm just sewing a tshirt!

I agree with Debbie Cook. Many sergers must be threaded in a certain order or one will keep breaking and maybe pull on a needle.

You do have to thread it up, upper looper first and then lower looper afterwards or threads will keep breaking. If needles are breaking or hitting anything, without even fabric in there at all, then maybe when you jammed it up the first time, the force even moved a looper a bit. So if you just even turn the wheel only by hand, with no fabric or thread in it at all, and if with good and new needles, anything metal is touching or hitting anything else metal, then best to stop, and not try to keep on sewing, until that is not happening anymore. Just because, a looper that got moved a bit, can just be moved back, one that actually gets bent or snaps off, from force of hitting something, needs to be replaced instead though. Same thing with your stitch plate or a foot too, if you got it on there a bit wrong or something, so metal is really hitting metal anyplace, just don't use it, and not with the foot pedal at all, until that is not happening anymore.

I'm really impressed! You just got your serger and you're already making something!

From what you've described, it sounds to me as though your lower looper thread is beneath the upper looper thread and it's causing your problems. I'll show you more with photos below.

But first let me say that the loopers pass so closely together when stitching that they almost seem to touch. So if you watched them without thread and you're wondering if you bent one, I just want you to know they are very close. I doubt you bent one.

Make sure your needles are in as far up as they should go. The point of the left needle is a bit higher than the right needle. And make sure the lower looper thread is not caught in the corner of the door I slammed my door closed once and didn't realize the lower looper thread (it's orange in the photo) was caught and it caused problems. And of course, make sure the threads are seated down in the tension disks and are not hooked anywhere else too. You can check by pulling the threads with the presserfoot up to make sure they are coming through the machine smoothly.

I am just going to use LL for lower looper and UL for upper looper to make it faster typing.

Most 4 thread sergers have you thread the UL first than the LL. This is so the LL thread ends up IN FRONT OF and OVER the UL thread.

This Singer Stylist 11 and the Viking H class 200s (they are the same machine) instructions are different than many other 4 thread sergers. I just want anyone else helping you to know this. These machines have you thread the LL first and lay the thread off angling towards the side in back. Then thread the UL and lay thread angling towards the back side too. Then the right needle and then the left needle. It will look like this when the machine is threaded Notice, at this point the LL thread is actually under the UL. To many people this might look wrong.

You lower the presser foot. Put your hand on the threads to hold them taut and pull them towards the back when you start stitching otherwise they can suck inward which can cause problems. Stitch a thread chain and notice how the LL thread is now IN FRONT OF and OVER the UL just as they are in all 4 thread sergers. This is the main thing I want you to check on your beginning stitches. If yours doesn't look like that photo than that is what your problem is.

I believe when you have started stitching your threads possibly sucked in and the UL did not go beneath your LL thread and that's why you had a problem.

Now, I don't want to confuse you, but you can also thread your machine so it looks like this with the LL thread already IN FRONT OF and OVER the UL See the looper threads are still laying towards the back with the needle threads under the presser foot off to the left. You will still need to hold them taut when you start stitching so you don't get them sucked in. Always start stitching by holding the thread tails and pulling them backwards while the thread chain forms without fabric in the machine to make sure everything is stitching as it should.

So in short, you can thread your loopers in any order as long as the threads look like they do in either photo. And as I said, ALWAYS hold them taut and pull towards the back when starting to stitch a thread chain.

I'll check back in to see if this helped you or if you need more info/help.

Also, remember you can always call Singer at the 800 number listed on the paperwork you received with the serger. A sweet english speaking lady will get your machine and bring it to the phone and help you.

I realized when I checked my links to photos that my machine looks a bit dirty.
