You'll be ok CR. What do you mean blew up? Once I had a Snap On air rachet and I was at the shop and pulled the trigger to move it after I oiled it and the head flew off and gears and bits flew all over the place. Anothr time someone had drilled a hole in a 20 oz soda bottle and left it laying around. A guy had a blower plugged into the airhose at 90 lbs pressure and just stuck it int eh bottle while we were talking and pulled the handle. It didnt shoot the bottle off, it blew up, scared the bujeebus out of us. You are def on your own about dropping a bell on your foot though. An old guy that I worked with had a saying "sometimes you gonna have that".
