1. loosen and remove old blade.
2. Clean out slot for the blades and make sure the lifting pieces under the hex wrench move freely. I had a couple that were packed with saw dust and didn\'t want to lower after being raised. It just took a little motion the free them up again.
3. Install new blade and tighten just enough so the y won\'t fall out as you rotate cutter head by hand to move to the next blade. Install the other 2 blades.
4. I set up the straight edge on out-feed table on the end of the blade closest to me. With the hex wrench slowly raise the blade till it just scrapes the straight edge without lifting it. Then repeat on the rear of the blade. Then check the center.
5. The only hard part is if you raise the blade too high you have to loosen the bolts to drop the knife and start again. Sometimes if the difference in height is too much, when you lift the rear of the blade after setting the front, the front is now too high. After each blade is set lock them in place before starting on the next.
6. After each blade is locked in place check each blade again to assure locking them down did not move anything. If everything looks good you should be ready to go.

Note. This was my first set of new blades so the replacement blades were shorter than the original blades. If the blades you are installing are identical to your blades you are removing I would lower the height adjustment at step 3 so you don\'t start out already too high.
