5.5 Operators and on-site staff must be familiar with the location and usage of the emergency stop button/key. Once any dangerous situation occurs (such as uncontrolled movement, abnormal noise, smoking, etc.), the emergency stop function should be activated immediately. Only after the product is in a completely stationary state can it be handled. It is strictly prohibited to directly attempt to physically or manually correct/block the product body when the product is not in a completely stationary state.
