FOr those of you who still pin up your gaurds, here is a story that will make you think next time you use your saw.
I was helping another contractor with a roof issue and he was trying to "cut in" the valley with the sheet tacked at the top with 2 sinkers. He was standing on the sheet, trying to hold it up off the deck with one hand and cutting with the other. He had a new Matsushita framing blade and the gaurd pined up. He had me worried so I got below him in case the sheet came loose. It did. The sheet came sliding off the roof whit him on it and he had a death grip on the saw which was still full throttle. I reached out to grab him and as I did he spun around and burried the saw in my hand. Took three surgeries but they saved my thumb which doesnt bend or have any feeling, but its there.
No I didnt sue, but I dont speak to him any more either.
