To set your blade, make sure it is unplugged from power source. run the blade all the way to the top, as high as it will go. If you don't have a stiff folding wood or plastic ruler, get one.
Now move your fence in close to where it will be and take up some slack in it.
Notice the teeth on the blade, every other one is to one side, ditto the other.
Now pick the tooth on the front side of the blade that points toward the fence, measure, same procedure for the back side of the blade. Now tighten the fence making sure neither end shifts.
Recheck the measurement, If correct tighten the fence all the way and readjust the blade high'th to where you will be sawing.
Also, If you do not have or use a push block, I'd advise to do so.
hope this helps. :)doak
