2.2 Charging Station Placement

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

2.3 Boundary Wire Installation

The boundary wire defines the mowing area. Lay the wire around the perimeter of your lawn, securing it with the provided hooks. Ensure the wire is taut and close to the ground to prevent accidental damage. For areas with obstacles or flowerbeds, create islands by looping the boundary wire. The mower uses this wire to navigate and stay within the designated area.

4.2 Blade Replacement

The mower uses a knife disc with 3 blades. For best cutting results, it is recommended to inspect and replace the blades every two weeks, or more frequently depending on lawn conditions and usage. Always wear protective gloves when handling blades and ensure the mower is powered off before performing any maintenance.

5. Troubleshooting

This section addresses common issues you might encounter with your Gardena Sileno Life.

5.1 Mower Stops or Displays Error

• Check Sensors: The mower is equipped with crash, lift, and tilt sensors. If the mower stops unexpectedly, check if it has encountered an obstacle, been lifted, or is on too steep an incline. Clear any obstructions.
• Boundary Wire: Ensure the boundary wire is intact and properly connected to the charging station. A broken or disconnected wire will prevent the mower from operating.
• Battery Level: Verify that the battery is sufficiently charged. The mower will automatically return to the charging station when the battery is low.

5.2 Uneven Mowing Results

• Blade Condition: Dull or damaged blades can lead to uneven cutting. Replace blades as recommended in the maintenance section.
• Mowing Schedule: Adjust the mowing schedule to ensure the entire lawn area is covered adequately.
• Lawn Obstacles: Ensure there are no temporary obstacles preventing the mower from reaching certain areas.
