how to thread the bottom thread of chain stich for the 5 thread industrial ovelocker, Kingtex.thank you?

Answer 1

I'm not familiar with Kingtex. The industrial models I have worked on though, usually have a diagram on the inside of an access cover, for handy reference. This information should also be located in the owner's manual.

If nothing else, you should be able to contact their customer service.

Good Luck
