Was completely thrilled with my new EGO Chainsaw, but as I'm using it more and more and on bigger logs, a problem is coming up. The saw is beginning to bind and smoke in the larger logs, and sometimes the cut bends off to one side. The cut ends of the logs are polished and dark, unlike earlier cuts when the unit was brand new, which were rougher and lighter. I've sharpened the chain a couple of times already and also "flipped" the bar. Research seems to tell me it's a chain-sharpening issue. I've sharpened chains on my gas saws for years, so I think I'm doing that right, that is unless there is something unique about this EGO chain. It almost seems like the cut is too narrow and the bar ends up jammed in it. Sometimes I can drive a wedge in behind the bar and spread the cut a bit wider which will help some. I know also that plenty of oil is on the chain....this is what I think is actually smoking.
