- Connecting the Charger: Plug the charging cable into the trimmer's charging port and then into a power outlet.
- Attaching Combs: To attach a comb, align it with the trimmer head and push it on until it clicks into place. To remove, pull it off gently.
- Attaching Trimmer Heads: To change trimmer heads (e.g., from the main trimmer to the nose/ear trimmer), twist the current head off and twist the desired head on until it locks.
Operating Instructions
The Braun MGK3221 offers versatile grooming for beard, face, and hair.
General Operation:
- Power On/Off: Press the power button to turn the trimmer on or off.
- Trimming Direction: For best results, always trim against the direction of hair growth.
Beard and Hair Trimming:
- Select Comb: Choose one of the four comb attachments based on your desired hair length (0.5 mm to 21 mm).
- Attach Comb: Securely attach the chosen comb to the trimmer head.
- Trim: Turn on the trimmer and move it slowly against the direction of hair growth. Ensure the flat part of the comb is in full contact with your skin.
- Detailing: For precise lines and edges, remove the comb attachment and use the trimmer head directly.
Nose and Ear Trimming:
- Attach Nose & Ear Trimmer: Replace the main trimmer head with the dedicated nose and ear trimmer attachment.
- Trim Nose Hair: Carefully insert the trimmer tip into your nostril, no deeper than 5 mm. Move it gently in a circular motion.
- Trim Ear Hair: Gently guide the trimmer around the outer ear and into the ear canal opening, avoiding deep insertion.
