"Been There, Milled That"
A couple of times, maybe 4 or 5, depending on how much you file off - more if it is just one or two stroke touch-ups. Oregon chains need raker adjustment more often than Stihl ones, as the cutters descends at a faster rate.
Forget the grinder, unless you rock out the chains - totally different story......:greenchainsaw:
Again, spot on advice. Good work Sawtroll!!
