1. Turn off the Navimow Terranox.
2. To avoid scratching, place the Navimow Terranox on a soft and clean surface in an upside-down position.
3. Prepare a cross-tip/Philips head screwdriver.
4. Remove the blade discs, then remove the upper cover of the blade discs.
5. Replace the blades, reinstall the upper cover of the blade discs, and finally mount the blade discs back in place.
