Well when igot my first machine 6 or so months ago I had the play field up on the metal arm (which was a gottlieb flimsy one) and not sure what happened but it fell on me while I was under it. It was like 4 am so the old lady was asleep so I started yelling for help I was ok as my back took the brunt but didn't wanna damage the game anymore so she held it while I crawled out and we both managed to get it back on the tracks and luckily it was ok , I had a few cuts and we have a funny story to laugh at .
