Safeguard manually-fed dough and cross-roll brakes.
(1) You must guard the top roll with a heavy-gage metal shield that extends over the roll to within six inches of the hopper bottom board.
The shield may be perforated to allow observation of the dough entering the rolls.
(2) You must provide an emergency "stop" bar that includes a self-engaging brake.
(i) Deenergize the drive motor.
(ii) Activate a spring-set magnetic brake.
(b) Activate the emergency "stop" bar before each shift to make sure it is functioning properly.
