How to Adjust Clippers? | Align Blades in 8 Steps

For the full breakdown, see our best Edge-Up Clippers guide.

If your clippers are pulling hair, cutting unevenly, or leaving irritation, the fix is almost always blade alignment—not dull blades or a dying motor. Properly aligned blades also reduce the risk of skin nicks, which is why this is the first thing most barbers check when a clipper feels off.

What You Need Before Adjusting Clippers

Grab three things before you start: a Phillips-head screwdriver that fits the blade screws snugly, a small brush or old toothbrush for clearing hair, and a clean, well-lit workspace. That’s the entire tool list—no special equipment required.

The adjustment itself works the same way on nearly every two-hole clipper blade, whether it’s a mains-powered Wahl or a cordless model from another brand. The visual markers—where the teeth sit relative to each other—are what you’re chasing, not a measured distance. Once you learn to see the tooth positions, you can align any clipper in under a minute on future attempts.

How Do I Align Clipper Blades Correctly?

That gap prevents the blades from pinching skin while still cutting cleanly.

Here is the full sequence that works for mains clippers and most detachable two-hole blades:

1. Power off and unplug the clipper before touching the blades. This is non-negotiable for safety.
2. Brush out all hair and debris from the blade area. Also wipe away old oil so the screws and alignment points are clearly visible.
3. Loosen the two blade screws slightly—just enough that the top blade moves freely. Do not remove them completely.
4. Wahl’s maintenance guidance specifies the upmost position for blade work.
8. Tighten the screws slowly and evenly, alternating between the two screws so the blade does not drift out of alignment as you work.

What Happens If the Blades Are Aligned Wrong?

The two most common mistakes—setting the blades flush and tightening one screw fully before the other—both lead to nicked skin or a clipper that stops cutting evenly. A flush, zero-gap setup should only be used if the manufacturer specifically supports it.

Skin pinching happens when the top blade sits level with or ahead of the bottom blade. The gap between them is what keeps skin out of the cutting action.

One more habit worth building: after you tighten and power the clipper on, run it for a few seconds and recheck the alignment. Vibrations can shift a blade that wasn’t tightened evenly. If the teeth have moved, loosen and realign. If everything still matches, apply a few drops of clipper oil before your next cut.

This adjustment is also the first thing to verify on new blades before you install them—brand-new blades often arrive slightly out of alignment from shipping.

FAQs

How often should I adjust my clipper blades?

Check the alignment every time you clean and oil the clipper, which most manufacturers recommend after every few uses. If you drop the clipper or notice it starting to pull hair, check sooner—impact is the most common cause of sudden misalignment.

Can I adjust any clipper brand using these steps?

The tooth-position method works on most two-hole detachable blades, regardless of brand. However, some manufacturers use different mounting hardware or tolerances. If your clipper’s manual shows a different alignment procedure, follow that instead of this general method.

Why do my clippers keep going out of alignment?

Loose screws from vibration are the most common culprit, but cutting dirty or matted hair puts extra strain on the blade assembly. Clean and oil regularly, and tighten the screws gently when you notice drift—don’t crank them, or you risk stripping the threads.
