4. Setup
4.1 Charging the Device
Before first use, fully charge the trimmer. The device uses a convenient USB Type-C charging interface. Simply plug the provided USB cable into the trimmer's charging port and connect the other end to a USB power source (e.g., computer, wall adapter). A full charge takes approximately 6 hours and provides about 60 minutes of use time.

4.2 Attaching/Changing Cutter Heads
To change the cutter head, gently twist and pull the current head off the main body. Align the desired cutter head (nose, sideburns, or eyebrow) with the main body and twist it into place until it clicks securely. Ensure the head is firmly attached before use.
5. Operating Instructions
5.1 Powering On/Off
To turn the trimmer on, push up the power switch located on the side of the device. To turn it off, push the switch down.
5.2 Nose Hair Trimming
Attach the R-shaped round cutting head. Gently insert the trimmer tip into your nostril. The 360-degree fit and three-dimensional arched blade, combined with the double-edged razor blade, allow for safe and effective trimming of nose hair without pulling. Move the trimmer slowly and carefully to trim unwanted hair.


5.3 Sideburns and Eyebrow Trimming
Attach the appropriate sideburns cutter head or eyebrow trimmer head. Use gentle, controlled movements to shape and trim sideburns or eyebrows as desired. For eyebrows, it is recommended to use the trimmer against the direction of hair growth for best results.

6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and hygiene of your trimmer.
6.1 Cleaning the Cutter Heads
After each use, turn off the trimmer and detach the cutter head. Use the provided cleaning brush to remove any trimmed hair from the blades and inside the head. For a more thorough cleaning, the cutter heads can be rinsed under running water. Ensure the heads are completely dry before reattaching them to the main body or storing the device.
6.2 Cleaning the Main Body
Wipe the main body of the trimmer with a clean, dry cloth. Do not rinse the main body under water as it is not waterproof.
6.3 Storage
Store the trimmer and its accessories in a cool, dry place, away from direct sunlight and moisture. Keep it out of reach of children.
7. Troubleshooting
If you encounter any issues with your Kemei KM-315 trimmer, refer to the following common problems and solutions:
- Device not turning on: Ensure the trimmer is fully charged. Connect it to a USB power source and allow it to charge for the recommended 6 hours.
