Question about Brother XL-3510 Mechanical Sewing Machine
My threading is tight on the top but loose at the back (bobbin side). I've tried different tensions, but it doesn't seem to be working. I also re-threaded the bobbin but it still isn't working. This problem just started how do I fix it?
Thank you - fixed it completely... though you have to take the bobbin case out completely to access that screw. - Remove the 2 screws holding the metal plate with a nickel and remove the plastic piece over the bobbin case - there is a small metal lever on the lower left side that needs to be pressed down. You can then remove the bobbin case. There are 3 screws - the center one is the tension adjustment. It was painted green on my machine. It appears that it is not a regular setting change, but a bad adjustment from the factory. So if you don't feel comfortable doing all that returning the machine for another will likely fix the issue.
