I have a brother 600 ul industry overlocker and need help with the threading

It may be that the blades are not as sharp as they should be. You can improve the edge on a 5000 grit whetstone or just try another set of blades.

ensure the tensioners are not too tight, reduce the tensioner to see if this helps. depending on thread type nylon or cotton etc the tension needs to match to control the feed to the needle if it is too high the thread who stick and when the needle makes the next stitch it can break the thread.
I hope this was useful.

Google your serger make and model for instruction manual.

Hi there

Please can you help. I bought a second-hand brother M14-B551 overlocker. The needle broke and i am now battling to thread . Where can i get some help.

It is, of course, possible to use overlock thread in a typical machine. Generally speaking, you only want to use overlock thread to overlock ("serge"). The reason for this if that while typical all-purpose or sewing machine thread has 3 strings wound together, overlock thread has only 2. When you are using 3, 4, or even 8 threads at a time with a serger, each strand doesn't necessarily have to be as strong as when you are sewing on a machine with only 2 threads. So, you physically could use the thread, yes, but it will not be near as strong, and you will probably have issues with breakage while sewing as well. The cost savings you think you may be saving by using overlock thread (which is, after all, considerably cheaper per yard), well soon be overrun with extra time sewing due to broken threads and overall less quality in your garment as it will be made weaker.
