5. Setup

5.1. Charging Station Placement

Select a suitable location for the charging station. It should be on a flat surface, away from direct sunlight and irrigation systems, with access to a power outlet. Ensure there is enough clear space around the station for the mower to dock easily.

5.2. Boundary Wire Installation

The boundary wire defines the mowing area. Lay the 160-meter boundary wire around the perimeter of your lawn, securing it with the provided fixing pegs. Ensure the wire is taut and flush with the ground. Maintain a minimum distance from obstacles as specified in the full manual. Connect both ends of the boundary wire to the charging station.

5.3. Initial Charging

Place the robotic mower into the charging station. Connect the power cable to the charging station and a power outlet. Allow the mower to fully charge before its first operation. The battery indicator on the mower or app will show the charging status.
