I have had my trimmer for over a year and really like it. It took me a while to get used to the bump feed, but buying better trimmer line makes it a lot easier. The problem i have had today is the line seems to start feeding out continually until it gets wrapped around the trimmer head. I've had a look at it and I think the bump part gets stuck in place, that is why it keeps feeding the line. Has anyone else had this problem?
