5.2 Zero-Gap Adjustment (Advanced Users)
The G Whiz trimmer can be adjusted for a zero-gap cut, providing an extremely close trim. This adjustment should only be performed by experienced users as improper adjustment can lead to skin irritation or cuts.
- Ensure the trimmer is off.
- Carefully loosen the two screws on the blade set.
- Adjust the top blade (cutter) slightly back so that it is flush with the bottom blade (comb), ensuring the cutting edge does not extend past the comb.
- Tighten the screws securely.
- Test the adjustment on a small area of skin before full use.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your trimmer.
6.1 Cleaning the Blades
- After each use, turn off the trimmer.
- Use the provided cleaning brush to remove loose hairs from the blades.
- For a more thorough cleaning, you may carefully remove the blade set (refer to manufacturer guidelines for blade removal specific to model 8986) and brush away any trapped hairs.
- Do not rinse the entire trimmer under water unless explicitly stated as waterproof.
6.2 Oiling the Blades
Oiling the blades regularly is crucial to reduce friction, prevent rusting, and maintain cutting efficiency. Wahl's high-carbon blades can rust if not properly maintained.
- Ensure the trimmer is clean and switched off.
- Apply one drop of Wahl blade oil to each corner of the top blade and one drop to the foot of the blade.
- Turn the trimmer on for a few seconds to allow the oil to distribute evenly across the blades.
- Wipe off any excess oil with a soft cloth.
