3. Setup and Installation
These replacement blades are designed for easy installation on compatible Wahl clippers. Always ensure your clipper is turned off and unplugged before attempting any blade replacement.
- Remove Old Blades: Carefully unscrew the two screws holding the existing blades to your clipper. Retain these screws if they are in good condition, or use the new screws provided.
- Clean Clipper Head: Use the included cleaning brush to remove any hair or debris from the clipper head and motor area. This ensures optimal performance and prevents clogging.
- Position New Blades: Place the new fixed blade (the larger, stationary blade) onto the clipper head, aligning the screw holes. Then, place the moving blade (the smaller, oscillating blade) on top, ensuring it sits correctly within the guides.
- Secure Blades: Insert the new screws (or your retained screws) into the holes and tighten them gently. Do not overtighten. Ensure the blades are aligned properly for a smooth cut. The top blade should be slightly behind the bottom blade to prevent skin nicks.
- Test Alignment: Turn on the clipper briefly to check for proper blade movement and alignment. Adjust screws slightly if necessary to achieve perfect alignment and smooth operation.

4. Operating Instructions
Once the replacement blades are securely installed and properly aligned on your Wahl clipper, operate the clipper as you normally would. These blades are designed to provide a sharp and precise cutting experience. Always ensure the clipper is well-oiled before each use for optimal performance and longevity of the blades.
5. Maintenance
Proper maintenance extends the life and performance of your clipper blades.
- Cleaning: After each use, turn off and unplug the clipper. Use the provided cleaning brush to remove all hair and debris from between the blades.
- Oiling: Apply 1-2 drops of clipper oil (not included) to the teeth of the blades before and after each use. This lubricates the blades, reduces friction, and prevents rust.
- Storage: Store the blades and accessories in the provided storage box when not in use. Keep them in a dry place to prevent corrosion.
6. Troubleshooting
If you encounter issues with your replacement blades, consider the following:
- Blades pulling hair: This often indicates dull blades or improper alignment. Ensure blades are clean, oiled, and correctly aligned. If the issue persists, the blades may need sharpening or further replacement.
- Blades not cutting smoothly: Check for hair buildup between the blades. Clean thoroughly with the brush. Ensure the clipper is adequately oiled.
- Excessive noise or vibration: Verify that the blades are securely fastened with the screws and that there is no loose debris. Proper oiling can also reduce friction and noise.
- Blades getting hot: This can be caused by lack of lubrication or excessive friction. Ensure blades are regularly oiled. If the problem persists, check for proper alignment or consider replacing the blades.
7. User Tips
- Always keep a spare set of blades on hand, especially if you use your clippers frequently.
- For best results, clean and oil your blades before and after every haircut.
- When replacing blades, take a moment to thoroughly clean the internal components of your clipper head to remove any accumulated hair.
- Store blades in a cool, dry place to prevent rust and maintain sharpness.
