I searched a variety of ways and couldn't find a thread on this. Sorry if it has been asked and answered somewhere.
We have a new Cobra class 3 sewing machine and when we go to backtack/reverse stitch the threads get bound up and locks the machine. When stitching in the forward direction everything seems to be working flawlessly. I read online it could be a tension issue, but after a lot of adjusting we seem to have the tension set appropriately so that the bobin thread doesn't show on the top side.
Any assistance would be greatly appreciated.
