The blade had slipped off the track on my band saw. I removed the cover...loosened the tension... and thought about unplugging the tool...Nahh - Nothing can happen! Well, it did and I'm damned lucky I don't have to explain a terrible outcome to anyone.
I was reaching up and about to put the blade on the upper pulley when I hit the switch...Very fortunately none of the blade was near the wheels (3 on this one) and the motor/pulley just spun freely. Am-I-ever- lucky.
From now on I won't take chances!! Now I know why Nahm gives those warnings on every program....
