how to set jointer blades

[old coot]

I am needing to change and set blades on a small Craftsman 4 1/8 in joiner model 149 236223. I don't have a manual and have never done this before. How do I get the height of the cutting edges the same? There is no adjusting screw under the back side of the blade.
Thanks, OC

You're welcome. I found a video on setting jointer knives that you also might find helpful. Video (http://video.google.com/videoplay?docid=2983839096587014177&q=jointer&total=33&start=0&num=10&so=0&type=search&plindex=0)
