Overlocker 614DE to thread - Sewing Machines

The tension settings on an overlocker are meant to be changed depending on the stitch your are trying to make. For the basic overlock stitch, it is usually recommended to start with the tension dials set at the midway point. However, machines differ, so those may even need to be tweaked. The tension is correct when all the threads meet in the middle of the fabric. It helps to test your machine using the 4 colors of thread so you can better see what is happening with the threads and you will be able to adjust each as needed.

For basic overlock stitch, usually the tensions are all set at the midway point, although there is usually some tweaking for any particular machine.
