I typically begin to start my saw by balancing it on my head. Then, after singing a verse or two from my favorite hymn book, I snap my head back sharply. As the saw drops, I'm doing two things: scratching my buttocks and violently jerking my head forward just as the saw passes my lips. At the end of the violent head-jerk, I grab the pull cord by my teeth and once again, snap my head back. My buttocks is doing quite nicely by this time, mind you. When it fires, I repeat the process, except this time, when it starts, I allow the running saw to drop onto my toe, at which point, I pull a Pele (you, know, the soccer player) and punt the saw upward into my hands, ready to cut. It sounds somewhat complicated, but it's really not that hard after practicing it a few times.
