How do I align my blades?

The bottom blade holes are larger than the shanks of the blade screws. When the blade screws are loosened the bottom blade can be aligned with the top blade. Tighten the screws and ensure that they are kept tight. The end of the top blade teeth should align 1/32" to 1/16"(.79mm to 1.59m") back from and parallel to the bottom blade. This ensures that the clipper does not cut too close and prevents the moving blade from touching the skin.
