Ouch I hurt my serger

You may have pulled just a slight bit too much on the thread and pulled the lower looper enough to collide with the upper. Maybe a thread hit a snag enough to pull the needle or one of the loopers out of alignment. The screws holding the loopers may not have been as tight as they should have been and one of the loopers may have moved out of alignment.

The screw at the end of the red arrow only holds a thread guide in place. If you look at the picture, slightly to the left and slightly above the one with the red arrow, you can see part of the head of the screw that holds the looper arm to the shaft. That screw may take a Phillips screwdriver (sometimes it will take an Allan key), or, if there's room, you may be able to get an appropriately-sized wrench on it. It may take a bit of trial-and-error to get that looper, the upper looper and the needles all moving together properly.

You would do well to solicit the services of a trained technician

Thanks I don't want to do that again.

Unfortunately, I tried that screw too (its stuck as well) plus hard to get an angle on, but I don't think it's going to help because it is actually the whole shaft that's loose. The looper is actually pretty tight to the shaft. Unfortunately to tighten the shaft I think I have to get inside the machine, and at the moment I have no clue on how to do that. I'll probably have to take it in.

Opened up the bottom of the serger, and found the loose screw, tightened it, and its great. Now I just have to figure out where the loopers are supposed to be positioned relative to the needle when they are at the highest point, and when they are at their lowest. Unfortunately I don't think that info is anywhere on the sears website, but I'll look. I have some info for a singer machine so I guess I'll start there.

Thanks!

As Ron mentioned earlier, now might be the time to seek professional help, especially since both loopers were not in the proper places. :-)

There will be a measurement between the lower looper and the left needle when the needle is at its lowest point and the looper is at its far left point. This varies from machine to machine. Then, there's the position where the point of the upper looper meets the bottom of the lower looper relative to the eye of the lower looper, and the distance between the two loopers as they cross. Then, there's the distance from the point of the upper looper and the left needle when the upper looper is at its far left position. These measurements all have to be fairly exact for the machine to perform well.

Stop! Stop! I'm getting loopy!!

Thanks for the help. Well I got it working. It actually wasn't too difficult to get the loopers placed since I knew which screws became loose to cause them to move so I only had to experiment moving them in one direction. Also there weren't too many options in how to place them without causing everything to run into each other which obviously wouldn't be a good thing. So anyways after quite a few hours of fiddling with it, it seems to be working.

I bought the machine used, so I didn't want to take it in and get it repaired for twice as much as I paid for it inititially, also I wasn't too worried about totally busting it since I hadn't paid that much for it. Once again thanks for the help.

I'm glad you were able to get it working. I don't know if you've had any/much experience working with sewing machines. If so, and perhaps even if not, you have learned that sergers are special. :-)

I have a Zenith DVD/VHS dual macine. I *can* use the VHS side for watching some of the old stuff, but mostly I use it to dub DVD copies of family VHS tapes and old shows we recorded back in the day (though I'll probably never get around to watching most of them).

You have to go through the bottom I have same issue
