That's really good to know...I thought that serger thread shouldn't cause a problem with tension disks. So...don't call the cops! LOL

I usually take my machines to the dealer about once a year for a 'tune-up', and I've never been told there was 'stress on the tension disks.' It usually just needs cleaning in the places I can't reach.
The reason you use 3-5 threads in a serger is to overlock the edges of the fabric and prevent raveling in addition to sewing a seam. The thread is thinner so it won't wind up making a heavy seam that would show through on the front of the garment. Polyester is a VERY strong thread.
Right now, I'm repairing a quilt that one of my grandsons has 'loved' a lot. The thread didn't break - it wore out where he or the dog chewed on it, where there was too much stress in places where I didn't do enough hand quilting, and on the edges of the binding.
The quilt police haven't raided my house yet for using serger thread in a quilt! LOL
