5. Installation Instructions

- Replace New Cutter: Position the small blade onto the clipper's driver, then place the large blade over it, aligning the screw holes.
- Adjust Position: Gently push the taper lever up to its highest position. Adjust the blades to ensure they are perfectly aligned, with the top blade slightly behind the bottom blade to prevent skin nicks.

6. Operating Guidelines
Once installed, ensure the blades are properly aligned and secured. For optimal cutting performance and to minimize friction, always apply a few drops of clipper oil to the blades before and after each use. This lubrication helps maintain sharpness and reduces heat buildup. Operate your clipper according to its manufacturer's instructions.
7. Maintenance
Proper maintenance extends the life and performance of your KBDS replacement blades:
- Cleaning: After each use, brush off any accumulated hair from the blades. For a more thorough cleaning, detach the blades and use a blade cleaning solution or isopropyl alcohol. Ensure blades are completely dry before reassembly.
- Oiling: Keep blades oiled. Apply 2-3 drops of clipper oil across the top of the blades and along the side rails. Run the clipper for a few seconds to distribute the oil. This reduces friction, prevents rust, and keeps blades sharp.
- Storage: Store blades in a clean, dry place when not in use.

9. Troubleshooting
- Blades not fitting correctly: Ensure the small blade is properly seated on the clipper's driver. Some minor adjustments or filing may be necessary for a perfect fit on certain clipper models.
- Poor cutting performance (not sharp, leaving hairs): Ensure blades are clean and free of hair debris. Apply clipper oil to the blades. If the issue persists, check blade alignment. Severely dull blades may require replacement.
- Blades clogging quickly: Regular cleaning and oiling are crucial. Ensure the clipper is clean internally and that hair is not accumulating excessively between the blades and the clipper housing.
- Blades getting hot: Excessive heat can be caused by lack of lubrication or prolonged use. Ensure blades are well-oiled before and during use. Take short breaks during extended cutting sessions to allow blades to cool.
