I have a dw734 planer and need to see a manual on
Do you have the blade set gauge that came with the planer? It is a little metal thing that looks like a bottle opener with 3 feet on it? Anyway, you need one, you can buy one at the Dewalt web site or where you got the planer. What it does is set the knives all to the same depth, every time, you can't miss. It rides on the drum, with the blades on the leveling screws, and a wrench in one of them, the jib in place, just snug, not tight, you lift each end of the knife up to just touch the gauge, then snug it up, move to the other end, and do the same thing, then to the middle, then back to make sure it is still on it's mark, If it comes up too far, and grabs the gauge, knock it down with a piece of wood, then move to the next knife, get them set all the same, then torque the jib screws up real tight. Give it a try. Hope this helps.
