Q. How do I align my blades? A. ALIGNING BLADES

1. 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 after the blsde is aligned and ensure that they are kept tight.
2. The end of the top blade teeth should be aligned 1/32" to 1/16"(.79mm to 1.59m") back from and parallel to the bottom blade. It is important to align your blade properly to ensure that the clipper does not cut too close and to prevent the moving cutter from touching the skin.
3. The extreme left hand tooth of the top blade must be covering or be to the left of the first small tooth of the bottom blade.
4. The extreme right hand tooth of the top blade must be touching the big tooth of the bottom blade.

This is always a problem with clippers, it's just a matter of holding the blades tightly in place and getting the screws in as tightly as possible without letting the blades go. This has always worked for me in the past.

It is very likely that one of the plastic pieces that hold the spring mechanism broke. If you send it back (with all the pieces and clipper) to Wahl Clipper, 2900 N. Locust St., Sterling, IL 61081, they will probably fix it for you for free.

I had the same problem and I eventually figured it out. The blade assembly has to be reassembled first then snapped back into place.

1. the bottom part has a little "nub" that the screws attach to
2. the second part is the thin piece of metal with a ridge
3. the white plastic thing, make sure the ridges are sandwiched together
4. the small blade, the blades must face each other
5. the large blade

use the 2 screws to hold the assembly together, once assembled it snaps into place on the clipper. See attached picture for how it should look once assembled.

It's STUPID that this is missing from the instruction guide that comes with the clippers.

I had the same problem with the Wahl Pro Series Rechargeable model 8552, and called Wahl service. Here is what I learned:
Never unscrew the screws on a Wahl blade (they use those funky nonstandard screws to deter you) -- that's the main thing. The whole blade assembly is supposed to come off by pulling it up and off from the teeth.
But, if you did it (as I did), you can put it back together this way:
1. Place the large blade down on the table (Wahl logo down), and place the small blade on top of it (if you look carefully, you will see how it lines up).
2. Insert the spring points into the two holes of the white plastic part (on mine, the spring kept slipping out and I finally used a drop of superglue on each hole until it would stay in long enough to complete the assembly). Place that piece on top of the small blade (see photo).
3. The bent metal piece with the two screw holes then gets placed on top of the large blade, with the center ridge of the bent piece over the straight center portion of the spring -- so that you have to hold it in your hand and push it together against the spring in order to align the holes of the entire thing. As you are holding that, put the screws in from below and tighten. It's awkward and if you are like me, it will take several tries before you can get it all lined up correctly and tightened. The photo below is what the final assembly looks like before snapping it onto the clipper.
3. Clip it in: At the top of the assembly in the photo below, notice the small bent metal piece that will fit into the back of your clipper in the hole. Once you fit that properly, push the whole assembly down onto the clipper until it snaps into place.
