Overlocker stopped cutting or doesn't cut properly
If the fabric is not cut properly by the overlock machine, or the machine pulls the fabric into the machine, the blades are probably dull or damaged.
When you use your locker a lot, the knives become dull, especially when using thick and special fabrics.
It often also happens that you accidentally sew over a pin, even then the machine will no longer cut properly.
Each lock machine has a bottom and an upper blade.
Regularly check that the blades are sharp by running your fingernail along the blade.
This way you can feel an unevenness immediately.
Insert new blades regularly in your serger for best results (or have your blades sharpened).
When changing the blades, make sure that the bottom blade stays just below the needle plate.
The upper blade should drop over the lower blade at its deepest point.
Put new blades in the machine yourself?
You can easily insert new serger knives in your machine yourself.
The video below shows you how.
Make sure that the lower knife is just below the stitch plate, and that in the deepest position the upper knife passes completely past the lower knife.

ADVICE: Performing periodic maintenance on your sewing machine is particularly important.
A well-maintained machine will likely run better and prevent annoying, time consuming, and costly problems later.
