Robot lawnmower vibrates excessively during operation, even on flat ground.

Safety first: Turn OFF the mower and disconnect the charging station. Wear gloves when handling blades.

• Check for missing blades: Ensure all blade positions on the disc are populated. Replace any missing blades and screws.
• Replace blades as a set: Always install a complete set of identical Einhell blades to maintain balance.
• Clean disc: Remove any caked grass or debris from the disc, especially if concentrated on one side.
• Inspect disc for bends: If the disc wobbles when spun by hand, replace it.
