In the table saw video demonstration below, we are cutting a sheet of plywood or particle board and place a hot dog in the path of the blade to simulate a user's finger. The SawStop system detects contact between the hot dog and the blade of the saw and stops the blade in approximately 5 milliseconds or less, resulting in only a small nick in the skin of the hot dog. For ease in viewing, we have removed the blade guard from the saw, however, we recommend using the blade guard whenever possible for maximum protection.
