Hi Hunter, forget the file guide, it is to time consuming, simply get a dozen new files, hold the saw in a vise, by the bar that is and with the file clean flatten from the back of the raker to the cutter. Hold the file under the cutter at 10 degrees down and get the top plate, then tilt the file 45 degrees the other way to really make it cut. Wish I could show you. I can almost get a round chain to cut as fast as a square chain. Hope this helps.
