husqvarna · Automower 310/315/315x
The mower detects an imbalance in its cutting system, which is usually caused by having an incorrect number of blades attached to the blade disc (either too few or too many).
Click steps to track your progress.
Turn off the mower and carefully inspect the blade disc.
Count the number of blades installed on the disc and ensure it matches the correct specification (usually 3 blades).
Replace any missing or damaged blades. Ensure all blades are correctly installed and secured.
If extra blades are present, remove them to restore the correct balance.
