1: Unscrew the blade, gently removing it and separating the top and bottom sections of the blade. Place the top and bottom blade into the zero gap adjustment tool which comes with the trimmer.
2: Loosen the screws lightly and push the top blade to the front.
3: Keeping the blade on the alignment tool clip it back on to the trimmer and add all the screws back in. You now have a zero overlap detailer for even closer trimming.
