Springpoles smack down chainsaw novices. The key things to remember are to find the apex between the ascending and descending sides and then attack on the inside at that point. Shave it, notch it, or make a face in it. Stand aside and cut on the tensioned side. I like to make a hinge sometimes, but it usually won't be necessary. I demonstrate that here, so you will have that little method in your toolbox. Attack it from the tensioned side, or too high or low, and you are likely to be injured. Do it right and the danger disappears.
