3. Setup and Installation

Proper installation of the replacement blade is crucial for optimal performance and safety.

  1. Power Off: Ensure your trimmer is turned off and unplugged from any power source before beginning the blade replacement process.
  2. Remove Old Blade: Carefully unscrew the two screws holding the existing blade set to the trimmer housing. Set aside the old blade and screws.
  3. Clean Trimmer Head: Use a small brush to remove any hair or debris from the trimmer head area.
  4. Position New Blade: Place the new T-shaped blade set onto the trimmer head, aligning the screw holes. Ensure the smaller cutting blade is positioned correctly within the larger stationary blade.
  5. Secure Blade: Insert the screws and tighten them gently. Do not overtighten, as this can warp the blade or damage the trimmer. The blade should be secure but allow for slight adjustment if zero-gapping is desired (refer to your trimmer's specific instructions for zero-gapping).
  6. Test: Plug in and turn on the trimmer briefly to ensure the blade moves smoothly and quietly.

4. Operating Instructions

Once the new blade is installed, your Wahl Professional trimmer is ready for use.

  • Preparation: Ensure hair is clean and dry for best results.
  • Technique: Use light, even pressure. The T-shaped blade is ideal for precise lines, edging, and detailed work around the neckline, ears, and facial hair.
  • Angle: Hold the trimmer at a slight angle to the skin for optimal cutting performance and to avoid irritation.
  • Cleaning During Use: Periodically brush away accumulated hair from the blade during extended use to maintain cutting efficiency.

5. Maintenance

Regular maintenance extends the life of your blade and ensures consistent cutting performance.

  1. Clean After Each Use: After each use, brush off any loose hair from the blade. For a more thorough cleaning, use a blade cleaning spray.
  2. Oil Blades: Apply 2-3 drops of Wahl clipper oil to the teeth of the blade after each use. Turn the trimmer on for a few seconds to distribute the oil evenly. This lubricates the blades and prevents rust.
  3. Storage: Store the trimmer and blade in a clean, dry place.
