4. Setup
Follow these steps to prepare your BaBylissPRO FXONE Trimmer for first use:
- Charge Battery: Before initial use, fully charge the FXONE lithium battery. Connect the provided dual-voltage charger to a power outlet and place the battery into the charger base. The 4-stage LED ring light on the battery will illuminate to indicate charging status and turn solid when fully charged.
- Insert Battery: Once charged, align the battery with the battery compartment at the base of the trimmer. Gently push the battery into place until you hear a click, ensuring it is securely seated.
- Blade Adjustment (Optional): For specific cutting preferences, the T-blade can be zero-gap adjusted. Refer to the 'Maintenance' section for detailed instructions on how to safely adjust the blade.
5. Operating Instructions
To operate your BaBylissPRO FXONE Trimmer:
- Power On/Off: Locate the power button on the trimmer. Press it once to turn the trimmer on. Press it again to turn the trimmer off.
- Trimming: Hold the trimmer firmly with the ergonomic grip. Use the precision T-blade for detailed work such as crispy edge-ups, hard lines, and other intricate hair cutting tasks. Always ensure the blade is clean and properly oiled before each use for optimal performance and to prevent pulling.
- Battery Monitoring: During use, observe the 4-stage LED ring light on the battery. This indicator will show the remaining battery life. Recharge the battery when the indicator signals low power to ensure uninterrupted operation.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your trimmer:
- Cleaning Blades: After each use, turn off the trimmer and use the included cleaning brush to remove any hair clippings from the blade. For a more thorough cleaning, press the quick release button to detach the blade. Clean the blade and the trimmer head area, then reattach the blade securely.
- Oiling Blades: Regularly apply a few drops of the provided clipper oil to the blades. Turn the trimmer on for a few seconds to allow the oil to distribute evenly. Oiling helps maintain blade sharpness, reduces friction, and prevents overheating.
- Battery Care: Store the FXONE battery in a cool, dry place away from direct sunlight and extreme temperatures. Do not attempt to disassemble or modify the battery. Always use the original BaBylissPRO charger for recharging.
- Storage: When not in use, store the trimmer and its accessories in a safe, dry place, preferably in its original packaging or a protective case.
