First Use Preparation:
- Before the first use, fully charge the shaver.
- It is recommended to test the shaver on a small area of skin (e.g., leg or arm) to ensure no adverse reaction.
- Your skin may take 2-4 weeks to adapt to a new shaver.
4. Operating Instructions
Turning On/Off and Travel Lock:
- To turn on the shaver, slide the power switch located on the side of the unit.
- To turn off, slide the power switch back to the off position.
- The shaver features a travel lock function to prevent accidental activation. Refer to the LED indicator for travel lock status.
Shaving Technique:
- Ensure your skin is clean and dry before shaving.
- The Solo Shaver is designed for stubble and hair up to 3 days growth. If hair is longer, pre-trim it with a hair trimmer for best results.
- Hold the shaver at a 90-degree angle to your skin.
- Gently glide the shaver over the skin against the direction of hair growth.
- Do NOT push the shaver down too hard. Excessive pressure can cause irritation, make the shaver warm, and prevent a smooth shave.
- For optimal results, stretch the skin taut with your free hand.

Cleaning the Shaver:
Regular cleaning ensures optimal performance and hygiene.
- Turn off the shaver and remove the foil head.
- Use the provided cleaning brush to remove any hair or debris from the foil and cutters.
- For a deeper clean, you may disinfect the foils and blades with an appropriate shaver disinfectant spray.
- Wipe down any excess moisture, allow to air dry completely, and then reassemble the shaver.

Foil and Cutter Replacement:
To maintain peak shaving performance, the foils and cutters should be replaced periodically.
- It is recommended to change the foils and blades of an electric foil shaver every 12 to 18 months, depending on usage.
- If you notice a decline in performance, such as tugging, pulling, or an uneven shave, it might be time to replace them sooner.
- Replacement Foils and Cutters (SB11) are sold separately.
