Well, if you love your saw that much......it may mess it up a bit more than you lie, but it is plenty saw. Don't let anyone make fun of teh 250 its a good saw. Do yourself a favor and use that crappy 26RM2 that came with it. Bad thing is you can't get the injecta sharp carbide chain in 325 pitch if I remember right. If you can get some chipper chain that would be better. the only way this will be bad on your saw is if you get the chain dulland keep on cutting without touchjing it up. That probably kills a lot of saws or else suck in a bunch of dirt/dust. you could also try chipping awaythe bark and most of the grit with your ax and then saw through the relatively clean wood after that. note that I am only suggesting using the chainsaw on the taproot, and only after you have cut out all the other roots with hand tools and dug down enough so you have work room. Additionally I would advise you not to do this by yourself, again the biggest danger is getting trapped by the stump when it falls over.
