So in my quest to keep all my saws running, and also because I just enjoy playing with my saws, I routinely start them up even if I don't plan on using them for any cutting. Call me weird.... So my questions are this.... Is it bad to shut off a cold saw a few seconds to a minute after starting it up? Will it prematurely wear doing this? Should I wait until they warm up before shutting them off? Does it even matter?
