Dan I have had the same problem as you have when I first got my saw. I had the dealer sharpen them for me as they dulled. I just bought new ones as when I got them back they just didn't cut well at all. I found out I could do a better job with my dremel, a small chainsaw stone, and sharpening attachment. So now that I have about 9 chains I just keep them all sharp and ready to go. I just don't like those bench top systems but that is just me.
