6. Operating Instructions
The Xiaomi Mijia Electric Drill features an HD display and a 360° stepless knob for mode and gear adjustments.
6.1 Mode Selection
The drill offers three main operating modes, selectable via the 360° stepless knob and display:
- A (Automatic Transmission Mode): The built-in smart chip automatically senses the torque required and adjusts accordingly. This mode is ideal for general screwing tasks, preventing overtightening and screw damage.
- M (Manual Transmission Mode): Provides precise control over speed (for drilling) or torque (for screwing). You can adjust through 30 levels using the stepless knob.
- Pulse Gear Mode: A safety pulse gear designed for novices. The intelligent chip controls intermittent rotation, ensuring safer use by preventing sudden high-speed starts.
6.2 Drilling and Screwing
The tool allows free switching between drilling and screwing functions. Use the appropriate bit for the task and material.
- Infinitely Variable Trigger: The speed gradually increases with the pressing force on the trigger. This allows for fine control over the operation.
- Slow-Stop Design: This feature protects the user, especially in high torque mode, by providing a controlled stop.

- Wall (Non-load-bearing walls)
