- To remove, gently pull the comb away from the blade.
Operating Instructions
Basic Trimming
- Ensure your hair or beard is clean and dry before trimming.
- Attach the appropriate guide comb for the desired length.
- Press the power button to turn on the trimmer.
- Hold the trimmer with the blade flat against the skin and move it slowly against the direction of hair growth.
- For detailing or outlining, remove the guide comb and use the bare blade carefully.
- After use, press the power button to turn off the trimmer.
Adjusting Cutting Length (if applicable)
The cutting length is primarily controlled by the attached guide combs. Some models may have a taper lever for fine adjustments; refer to the physical device for this feature.
Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and performance of your trimmer.
Cleaning the Blades
- Turn off the trimmer and unplug it from the charger.
- Remove any attached guide comb.
- Use the provided cleaning brush to brush away loose hairs from the blades and the trimmer body.
- For a more thorough clean, the blades can often be rinsed under running water (check product's water resistance rating; if not specified, avoid direct water contact with the main body). Ensure the trimmer is completely dry before storage or next use.
Oiling the Blades
- After cleaning, apply a few drops of the provided lubricating oil onto the blades.
- Turn on the trimmer for a few seconds to allow the oil to distribute evenly.
- Wipe off any excess oil with a soft cloth. Oiling helps maintain blade sharpness and reduces friction.
Storage
Store the trimmer in a cool, dry place, away from direct sunlight and moisture. Keep it out of reach of children.
Troubleshooting
