In this video I’m showing you exactly how I replace the blade on the WAHL Cordless Detailer, how I line it up properly, and how I zero gap it the safe way. If your Detailer isn’t hitting like it used to, or you’re getting those little snags and it’s not lining up clean on the edge-ups, a fresh blade and a proper adjustment can bring it right back. I keep it super simple so you can do it at home or in the shop without overthinking it. I walk you through the blade swap, how to set the cutter and the stationary blade so they’re even, and how to dial in that zero gap so you get crisp lines without turning your trimmer into a skin-eater. This same method works on any WAHL Detailer, so once you learn it, you’re good for future blade changes too. If you want the exact replacement blade I’m using, I’ve linked it, and you can check my Amazon shop for the rest of the tools I use.
