Have you checked out hair salon supply stores, like Sally Beauty Supply. They will sell generic and brand specific blades for all cutters.

The two screws of the blade guide are tightened completely. Adjust the tension between the blade and the blade guide with the large plastic screw on the side of the trimmer (this allows the blade to move rapidly from side to side). I plug it in at this time and when the cutting blade begins to move the clipper makes much louder noise. This is normal but it sounds like it is broken, it isn't. Adjust the cutter slightly past movement. You don't want it to bounce on the guide

The blade (the small one with several holes) gets attached to the slide spring (the thin pieces of metal with a small gap between them), through the two diamond shaped holes, with tension on the slide spring keeping the blade in position. The blade guide, the large plate with only two holes, gets mounted with the two screws. The rough surfaces of both blade and blade guide face each other.

ok the blade latch only holds the blade into place.

the hinge assembly which the latch sits behind needs to be open, there is a silver piece with two ridges on, place a flat bladed screwdriver behind the hinge and this will lever open you can then slot the blade onto the hinge and close shut with the clipper running.

try contacting your supplier or send the to an oster service station such as www.angliaclipperservices.com

Make sure you have "3 in 1" oil nearby and oil the blades before and after each use. Use an old toothbrush to clean the blades while wet with oil and then wipe the excess oil and crud off with a paper towel. Store in a dry place away from bathroom humidity. I've found that the cheap ones just don't do the job and a while back, I decided to pony-up for a decent one. So, the reality is, cheap ones don't cut that well and even the best ones won't cut well if you don't keep them cleaned, oiled and rust-free.
