| Auxiliary unlocking instructions |
 | When the safety door switch is working normally, the arrow points to the "locked" sign, and the anti-rotation screw must be in a tight state; In special circumstances such as power failure or malfunction of the equipment, if you want to open the protective door, you should first loosen the screw next to the arrow knob; Then use the tool to point the arrow knob to the "unlock" sign. At this time, the safety door switch is unlocked, the bolt can be pulled out, and the protective door can be opened. |
