Answer:
- Power off the mower.
- Put on protective gloves.
- Carefully turn the mower over so the blade disk faces upward, and place it on a soft, clean surface (such as a towel or mat). Take care not to damage the camera module on the front top edge or the LiDAR module on the top of the mower.
- Loosen all blade screws using a manual cross-tip (Phillips) screwdriver. Do not use a power or electric screwdriver—its high-speed rotation could cause injury to your hands or fingers.
- Replace all blades and screws with new, compatible parts.
- Tighten the screws securely—but avoid over-tightening—so the blades stay in place while still pivoting freely (this is intentional and part of the design).
