Setup
Boundary Wire Installation
The boundary wire defines the mowing area for your robotic lawn mower. Proper installation is crucial for optimal performance and safety.
- Place the Charging Base: Select a suitable location for the charging station, preferably on a flat surface near an outdoor power outlet and away from direct sunlight or heavy rain.
- Lay the Boundary Wire: Use the provided measurement gauge to maintain the recommended distance from obstacles (e.g., walls, flowerbeds). Secure the wire to the ground using the boundary wire pegs. Ensure the wire forms a continuous loop around the desired mowing area.
- Connect Wire Ends: Strip the ends of the boundary wire and connect them to the designated terminals on the charging station.
- Power On Station: Plug in the power adapter to the charging station and an outdoor power outlet. The indicator lights on the charging station will confirm a successful connection.
