How to adjust hair clipper blades

The simplest way to adjust any hair clipper blade is very simple. Below are the steps to adjust your hair clipper blade so it can be zero gapped . Having a zero gapped blade will make your blades cut closer for sharper fade, and blend. It’s important to have your clipper blades adjusted so you can blend skin fades, and skin tapers easier. The only tool you’ll need is a screwdriver.

 Easy 5 STEPS


Step 1 – Start by loosening the two screws on the back of the blade of the clipper. Don’t loosen them up all the way, but just enough to move the top blade (guide) up and down.

Step 2 – Now that you can move the top blade up, and down what you want to do next is tighten the screws just a tad bit, but not tight. Enough that you can still move the guide blade up, and down.

Step 3 – Now with the lever in the closed position, or lever all the way up towards the front of the clipper blade you want to set the blades as close as possible with your fingers moving the guide (bottom blade) blade to the cutting blade (too blade) together until there almost horizontal ( almost even to each other) to each other, but allowing a small gap between the blades. Doing this by looking, and moving the blades from the front of the clipper. This requires good eyesight.

Step 4 – Now that you have the blades set, and aligned to your liking. Tighten the screws in the back of the blade. Flip the clipper to back side, and hold blades together with one hand to avoid the blade from moving or getting misaligned, and with your other hand tighten the blades.

Step 5 – You want to tighten them slowly, and one by one by turning one screw a tad bit then tighten the other screw a tad bit until the screws tighten all together. By doing this it reduces the chance of the blades getting miss aligned, or overlapping the top blade when you tighten them to fast.


When adjusting clippers keep in mind the trick is to leave a little space between the lower blade (cutter blade), and the top blade (guide blade).

You don’t want the bottom blade overlapping the top blade because it’ll cut people. On some clippers you also don’t the blades to be close to each other, or too flush to each other, because when you turn the clippers on the vibration can cause it go over the top blade so allow a small space.

This happens mostly with Wahl clippers. On Oster, and Andis clippers I find that you can set them pretty flush to each other, and they won’t cut people.
