| Auxiliary Unlocking Instructions |
 | When the safety door switch is operating normally, the arrow points to the "Locked" mark, and the anti-rotation screw must be in a tightened state. In special circumstances such as equipment power-off or malfunction, if it is necessary to open the guard door, the screw next to the arrow knob should be loosened first. Then, use a tool to turn the arrow knob to the "Unlocked" mark. At this point, the safety door switch is unlocked, the latch pin can be removed, and the guard door can be opened. |
