My Son came over and wanted to borrow my truck, he got the keys and I started my T8 to do some blades, he came back and said DEAD battery, I thought I turned it off , but went out the one thing led to another I then went back to my T8 and it has been running for 3+ hours it is pretty hot, hope I didn't cook it, letting it cool down now, any one else do this or am I freaking out. plus arn't the bearings like plastic bushings?
