How does one cut one’s own head off with a chain saw?

Watch The Andromeda Strain - it has such a scene.

Rent the movie Andromeda (the 4 hour extended version). There is a scene in it where one of the townspeople who didn't die immediately used a chain saw to cut off his head.

Warning though, this version of the movie was a little boring.
