Robot mower vibrates excessively, especially when the blade motor is running

Safety: Turn OFF power, disconnect the battery, and wear gloves before touching blades.

• Check blade count: Ensure all blade positions on the disc are populated with blades and screws.
• Replace blades: Install a complete new set of Mammotion blades, tightening all screws evenly.
• Inspect disc: If vibration persists, remove the disc and check for warping. Replace if bent.
• Do not operate the mower with missing or mismatched blades, as this can damage the motor and bearings.
