3.8.7 Safety by Using Trip Guards
Trip guard in machine is comprised with tripping device which enables quick stopping or
reversal of the motion of machine as soon as the operator approaches within the reach of
dangerous parts. Tripping device and the trip guard works in close conjunction with each
