Maintenance for Cutting Blades and Motor

WARNING

• Always wear protective gloves when inspecting, cleaning, or replacing the cutting blade.
• DO NOT use an electrical screwdriver to tighten or loosen the cutting disc. Always use the correct screws and original blades approved by Mammotion.
• Replace all cutting blades and their screws simultaneously to ensure a safe and effective cutting system.
• DO NOT reuse the screws, which may cause serious injury.

• To ensure optimal performance during long-term storage, keep the hub motor shaft dry and clean. Regular maintenance of the motor shaft helps prevent dirt and moisture buildup, which can affect the motor’s function. The motor has an expected lifespan of 1500 hours of operation. 
  
• Blades are considered wear parts and should be replaced if they become severely worn. It is recommended to replace the cutting blades every 3 months or after 150 hours of use. For thicker grass, more frequent blade replacement may be necessary.
  
• Wet grass is more likely to stick to the blades and bottom of the robot, which can impair performance and lead to the need for more frequent cleaning. For optimal performance and long-term lawn health, it is recommended to avoid mowing during heavy rain or when the grass is excessively wet.
  

How to replace a cutting blade

1. Turn off the robot.
2. Place the robot on a soft, clean surface, ensuring it is in an upside-down position. Please take care not to press on the vision module.

3. Remove the old cutting blades with the included screwdriver with Phillips bit.
4. Install the new cutting blades (B) using the included washers (C) and screws (A). Ensure that the blades can rotate freely and are securely installed.
