I tried sharpening chains before and I end up with ones that cut at about a 40* angle when I sharpen them. So I gave up and just bought new chains and swaped them out. I think mine were just the cheap homelite stuff on the hangers at Home Depot. I will start out with the chain adjusted to that you can pull 1/2 the guide tooth out of the bar. Within 10 minutes I had to stop because the chain is sagging 1" below the bar. Like I said it is just a cheaper echo saw I picked up for my HOA. I got an echo because the HOA blower and weed wacker are both echo. So I wanted them all the same brand so no confusing the gas oil mix.
I used to run a 440 magnum with a 24" bar when I was working on a clearing crew. My arms would be jello after a 10 hour day running that beast.
