The very minute you think you’ve got a chainsaw under complete control is the very moment it messes you up. Take this fine example in Mr. Gardner’s news report. Just a regular scene of a tree coming down — except if you watch the clip, the guy in the back nearly does a faceplant on the bar of his saw.
At that point, the saw was hung and not spinning, but it could have easily gone the other way or popped loose and kicked back at him at any point where the man was off balance. Luckily, no one was hurt and it made for a good news report, but I’m sure it was on the worker’s mind after the camera cut.
