Question: why are my wahl clippers so loud?
Answer: The clipper should go from its nice buzzing sound to a loud clattering sound. ... (If the clipper does start clattering, turn the power screw anti-clockwise around ¼ turn and test again.) 3) When you tune your clipper you will alter the alignment of the top (cutting) blade, so you will now need to re-align the blades.
