6. Installation (Blade Replacement)

Follow these steps to safely replace the blades on your Kress Mission robotic lawn mower:

1. Prepare the Mower: Ensure the robotic lawn mower is completely switched off and disconnected from its charging station or power source. Turn the mower upside down to access the blade disc.
2. Wear Protective Gear: Put on heavy-duty gloves and eye protection before proceeding.
3. Remove Old Blades: Using a suitable screwdriver (often a Phillips head, refer to your mower's manual), carefully unscrew the old blades and their mounting screws from the blade disc. Keep track of the screws if you intend to reuse them, though new screws are provided.
4. Clean the Blade Disc: While the blades are off, take the opportunity to clean any grass clippings or debris from the blade disc area.
5. Install New Blades: Place a new vhbw replacement blade onto the blade disc, aligning the mounting holes. Secure it with a new mounting screw provided in the package. Do not overtighten the screws; the blades should be able to pivot freely.
6. Replace All Blades: For optimal cutting performance and balanced axle load, it is highly recommended to replace all blades on your robotic lawn mower at the same time, even if some appear less worn.
7. Verify Installation: Gently check that all new blades are securely attached but can still pivot. Ensure no tools or debris are left on the mower.
8. Resume Operation: Turn the mower right side up, reconnect power, and resume normal operation.

7. Maintenance and Storage

• Replacement Frequency: The frequency of blade replacement depends on your lawn's size, grass type, and mowing schedule. Generally, blades should be inspected regularly and replaced when they show signs of dullness, chipping, or bending. Dull blades can tear grass, leading to an unhealthy lawn.
• Storage: Store unused replacement blades and screws in their original packaging in a dry, safe place, out of reach of children and pets.
• Disposal: Dispose of worn-out blades responsibly. They are sharp metal objects and should be handled with care. Check local regulations for metal recycling.

8. Troubleshooting

If you experience issues after replacing your blades, consider the following:

• Uneven Cut: Ensure all blades were replaced simultaneously. A mix of old and new blades can lead to an uneven cut. Also, check that blades can pivot freely and are not overtightened.
• Increased Noise/Vibration: This could indicate an unbalanced blade disc. Double-check that all blades are correctly installed and that the screws are tightened appropriately (not too tight, allowing pivot).
• Blades Not Cutting: Verify that the blades are installed with the sharpened edge facing outwards and are not obstructed by debris. Ensure they are new and sharp.
