3.3. Attaching Guide Combs

4. Operating Instructions
4.1. General Trimming
- Ensure the trimmer is fully charged.
- Select the appropriate trimmer head for your desired grooming task (e.g., Full-size Trimmer for general hair, Precision Trimmer for detailing).
- Attach a guide comb if a specific hair length is desired.
- Press the ON/OFF switch to turn on the trimmer.
- Hold the trimmer against the skin, moving it slowly and steadily against the direction of hair growth.
- Turn off the trimmer after use and proceed with cleaning.
4.2. Using Specific Attachments
Full-size Trimmer
Use this head for general hair cutting and shaping on larger areas. Move the trimmer smoothly over the desired area, ensuring even coverage.
Precision Trimmer
Ideal for creating sharp lines, defining sideburns, and trimming smaller, intricate areas. Use without a guide comb for the closest trim or with a 3mm precision comb for short stubble.
Detail Shaver
Designed for a close, smooth shave on small areas or to clean up edges around your beard or hairline. Use gently on dry skin.
3-blade Shaver
This attachment is specifically for finishing lines and edges, providing a clean and smooth result similar to a close shave.
Nose Trimmer
Carefully insert the nose trimmer head into the nostril or ear. Move it gently in a circular motion to trim unwanted hair. Do not insert the trimmer too deeply into the nasal passage or ear canal.
Engraving Trimmer
Use this head for creating intricate hair patterns or designs. This requires a steady hand and careful movement. It can be used with the 3mm engraving comb for specific design depths.
5. Maintenance and Cleaning
5.1. After Each Use
- Turn off the trimmer and detach the trimmer head.
- Use the provided cleaning brush to remove hair clippings from the blades and the trimmer unit.
- Rinse the trimmer heads under running water if they are washable (refer to product specifications for water resistance). Ensure the main unit does not get wet as it is not waterproof.
- Allow all parts to air dry completely before reattaching or storing to prevent rust and bacterial growth.
5.2. Lubrication
Periodically apply a small drop of lubricating oil (if provided) to the blades to maintain optimal performance and extend blade life. Turn on the trimmer for a few seconds after oiling to distribute the oil evenly across the blades.
5.3. Storage
Store the trimmer and its accessories in a dry place, away from direct sunlight and moisture, when not in use.
