Blade Replacement:
For optimal performance and hygiene, it is recommended to replace trimmer heads periodically, especially if you notice a decrease in cutting efficiency or increased irritation. Replacement heads can be purchased separately.
Troubleshooting

- Reduced trimming performance: Clean the trimmer head and blades thoroughly to remove any hair buildup. If performance does not improve, consider replacing the trimmer head.
- Skin irritation: Ensure blades are clean and sharp. Use the trimmer on clean, dry skin or with shaving cream/gel for wet use. Avoid pressing too hard against the skin.
