Smart move I know. I'm fine, but it's got us to talking here at work. Do you change your blades with a impacts? I've taken them off that way, but I always read to put them on with a torque wrench. I always use a big ol rachet.
I have used an electric impact for many years with absolutely no problems. I have a feel for the tightness, once it starts to bang I stop when tightening. I have never checked the torque, it is a feel thing you become familiar with.
People don't realize the vibration from the impact works at loosening the blade bolts so much easier than steady hard pressure.
