A RED Emergency Power Off (EPO), mushroom style, manual pushbutton switch is mounted on the top panel, behind the guide rails. This pushbutton must be pulled out to enable machine operation and may be pushed or “slapped” to the “in” position to turn off control power and stop the machine. In an emergency, push or slap this button to the “in” position to cut power and stop the machine. This type of button is also referred to as an E-Stop.
