2. Setup and Installation
Follow these steps to install the THTEN AF-100 replacement blades onto your compatible Black & Decker trimmer head.
- Prepare the Trimmer: Ensure the trimmer is turned off and unplugged (or battery removed) before beginning installation. Clear any grass or debris from the existing trimmer head area.

- Attach Blades to Head: The AF-100 blades are designed for easy installation. Simply push each blade into the designated string socket on the trimmer head. The blades should automatically lock into place with assistance from the side push buttons. Secure them using the provided screws and nuts with the hex key.
- Reassemble and Verify: Once all blades are securely attached, reassemble any removed parts of the trimmer head. Gently pull on the blades to ensure they are firmly seated and will not detach during operation.

3. Operating Instructions
Once the THTEN AF-100 blades are securely installed, operate your Black & Decker trimmer according to its original manufacturer's instructions. The fixed dual blades are designed to cut through various types of grass and weeds efficiently.
- Safety First: Always wear appropriate personal protective equipment (PPE) including safety glasses, long pants, and closed-toe shoes when operating a string trimmer.
- Cutting Technique: Use a sweeping motion to cut grass and weeds. Avoid hitting hard surfaces like rocks, concrete, or metal fences, as this can damage the blades or the trimmer.
- Blade Performance: The serrated edge of the blades is optimized for cutting thicker weeds.

4. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your THTEN AF-100 replacement blades.
- Inspection: Before each use, inspect the blades for any signs of wear, cracks, or damage. Replace any damaged blades immediately.
- Cleaning: After each use, clean the blades and the trimmer head to remove grass clippings and debris. This prevents buildup that can affect performance.

5. Troubleshooting
If you encounter issues while using your THTEN AF-100 replacement blades, consider the following:
- Blades Breaking Frequently: This can occur if the blades repeatedly strike hard objects (rocks, concrete, thick tree trunks). Adjust your trimming technique to avoid such impacts. Ensure blades are securely fastened.
- Ineffective Cutting: If blades are not cutting effectively, they may be worn or damaged. Inspect and replace them if necessary. Ensure the trimmer motor is operating at full power.
- Blades Not Staying in Place: Verify that the blades are correctly inserted into the string sockets and that the screws are tightened appropriately.
