husqvarna · Automower Technical Manual
The corridor width setting is too high for the Automower to successfully navigate a narrow opening or passage while following the boundary wire.
Click steps to track your progress.
Reduce the corridor width successively until Automower can pass through the passage.
Install a guide wire through the passage to prevent the Automower from running on a small corridor width. Use the function 'Test IN'.
Ensure the passage is free from obstacles.
