I am trying to hem my slacks but the bobbin thread keeps bunching. I have followed the instructions but it still doesn't work. Can anyone help me? It' s shark model 412n.
To stop the bunching I just used compressed air (like a keyboard cleaner) to clean out the bobbin compartment, especially the bobbin tension. I'm sure you have tried similar things, good luck.
