4.2 Oiling Blades
Apply a drop of the provided blade oil to the blades before and after each use. This ensures smooth operation and extends blade life. After applying oil, turn on the trimmer for about 5 seconds to distribute the oil.
4.3 Battery Care
To maintain battery health, ensure the battery is fully charged at least once every 6 months, especially if not used for extended periods. Do not store the battery completely discharged for long durations. If the battery is very low, charge it for at least 1 minute before use.
5. Troubleshooting
5.1 Device Noisy or Overheating
If the trimmer becomes noisy or overheats, it may indicate insufficient lubrication. Turn off the device, remove the blade, apply a drop of oil to each indicated point on the blade, then reattach the blade. Turn the device on for approximately 5 seconds to allow the oil to spread.
5.2 Trimmer Not Turning On
Check if the battery is charged. If the battery is low, charge the trimmer for at least 1 minute. Ensure the travel lock is not activated (press and hold the power button to toggle).
