One morning, it was so quiet to jog on the treadmill without having to turn on the motor when the rest of the people in the house need their peace and quite! Well, since I was not sure if that was the proper way to work the belt without damaging the motor when the power is off, I stopped the jogging shortly after a few minutes. There was no manual to consult. I wonder if I would ruin the motor by jogging on the belt when the power is off?
