I have the scars on my rail from the very first time I used the ATF 55. I knew it was a plunger, but for 50+ years, i had been using Milwaukees and PC's etc as plunger saws by raising up the heel and dropping down into the middle of whatever i was cutting. Usually plywood for form lumber (rough cuts) When I first set up my ATF, even tho i knew how it should work, i guess I got a little extracited and picked up the heel til the plate cleared and started the saw while dropping the plate back down. DEFFINITELY a wrong move.
One of those lessons I need the class on only once, but, to answer your question, YES, it can happen if you do something stupid like I tried. I won't get rid of that guide bar as it is a great reminder. ANNNND, luckily, the scars ain't on me.
