Robot mower vibrates excessively or bounces while mowing.

Safety first: Turn OFF the mower and disconnect the battery. Wear gloves.

Steps:

• 1. Check blades: Ensure all blades are present and of equal type and wear. Replace the full set if any are damaged.
• 2. Clean disc: Remove caked grass from the disc to eliminate imbalance.
• 3. Inspect disc for bends: Sight along the edge of the disc; if warped, replace the cutting disc.
• 4. Tighten mountings: Verify that the blade motor and disc mounting screws are tight.
