Why can't the Mijia Brushless Cordless Drill 2 be started?

If the Mijia Brushless Cordless Drill 2 can't be started, please refer to the following steps to troubleshoot:
1. Please confirm that the pre-start procedures are correct, the drill bit is properly installed, that the chuck is locked or not jammed, and that you are pressing the On/Off button to start the device.
2. Please check the battery level; the battery icon will remain red when the battery is low. The drill will not start if the battery level is too low. Please fully charge the battery before trying again.
3. Please confirm that the drill bit is in the locked position. The drill cannot be started when it is locked. Please unlock it before trying again.
4. If you use the device for an extended period or in a high-temperature environment, overheating protection could be triggered, preventing the drill from starting. Please allow the device to cool down before using it again, or use it in a well-ventilated environment.
5. For safety reasons, the drill cannot be started while charging. Please ensure the device is fully charged and the charging cable is disconnected before attempting to power it on.
6. If the issue persists, please contact the after-sales service center for further assistance.
