Maintenance
To ensure optimal performance and longevity of your Wahl trimmer, regular maintenance is recommended:
- Cleaning: After each use, rinse the trimming heads with water and allow them to air dry. Use the provided cleaning brush to remove any trapped hairs from the blades and internal mechanisms.
- Oiling Blades: Periodically apply a small amount of the included blade oil to the trimmer blades. This helps to keep the blades lubricated, ensuring smooth operation and preventing dullness.

If you encounter any issues with your Wahl trimmer, consider the following:
- Trimmer not turning on: Ensure the device is fully charged. Check the charging cable and adapter for any damage.
- Reduced cutting performance: Clean the blades thoroughly and apply blade oil. Ensure the correct attachment and guide comb are securely in place.
