Wahl Hair Clipper Pulls or Doesn't Cut Hair

October 14, 2019
If your Wahl hair clipper pulls hair or simply doesn't cut it, you can correct the problem by adjusting the power screw, probably located on the side of the clipper. Turn on the clippers. Turn the screw slowly clockwise until you hear a "clattering" noise. Then turn the screw counterclockwise until the clipper is as quiet as possible. The clipper is now adjusted correctly. If you find that you have to adjust the power screw multiple times during the cut, perhaps the chassis screws have vibrated loose. Gently tighten all other screws on your clipper, then readjust the power screw. Another cause of this symptom is that the blade screws are too tight. They should be snug, but not as tight as possible.
