My dewalt dw733 12 1/2'' planer is thumping and knicking the wood as it planes. I tried replacing the blades, readjusting the blades,and taking smaller bites when planing. It's like snipe in the middle of the board. Please help. Rusty.

Try going back to basics. Yes, I've been caught out by something silly and obvious! Are they the correct OEM blades for that model? Are there washers/spacers fitted on the mount screws? Are they the correct screws? Have all the access covers and cutting guides been refitted correctly? Has the depth guide been set correctly?
Some planers can be fitted with thicker or thinner blades depending on the model. Washers/spacers may need to be fitted under the blades so they are 'trapped' and lift the blade high enough to clear the screws. Are the original screws 'dome head' or 'countersunk'? Domes will sit higher and touch the wood as the blade spins. The access covers, cutting guides and depth gauges could be out of position affecting the cutting platform.
Replace the blades. It sounds like they're pulling up the grain too easily rather than cutting it. (Its like when you shave with a dull razor blade) It could also be the species of wood and/or the direction you are running it through the planer.
have you checked you have not taken a chunk out your blade. also you have to make sure the blades are set spot on. other wise it will affect the balance. good kuck
Use a backing board, such as high grade 3/4 inch plywood under the board you are planing, and you should be able to get down to 1/16, depending on the stability of the board you are planing. Take light cuts and flip it over to cut on both sides. Sounds like you might be making a guitar?
Good luck.
It sounds like your blade holder assy has become misaligned on the blade drive shaft. Try if you can to use a straight edge on 2 planes 90 deg apart and see if there are any gaps in either of the srtaight edges. I suspect that the blade drive holder has become slightly dislodged from the drive collar on one end allowing the blade drive to tilt on the drive shaft. I had the same thing happen on another brand named Planer and it was a matter of reseating the collar to cure the stripes. Sure took a long time to sort out. Good Luck.
There are two adjustments. First find the screw on the right side that allows loosening of rear baseplate. Once loose, another screw jacks the base up or down. They are both hex heads on mine.
Turn jack screw until a straight edge along the base just clears the cutter. Spin the cutter once to make sure both edges are the same depth and that both clear the straight edge.
For the front shoe, turn adjustment handle to zero. Remove the adjustment handle from the front shoe and find two vertical slots at the front. Two screws (hex heads) allow loosening of shoe. Once loose, the shoe can be adjusted by sliding up or down. With a straight edge held along the rear base and touching the front base, align the front shoe so straight edge barely clears blade and tighten screws. The front and back base should line up. Replace adjustment lever and recheck zero cut clearance as well as maximum depth. Readjust as necessary. If zero clearance is not an issue, the bases can be set to allow deeper cuts than factory specified. It's a powerful planer so if you're cutting softer woods, a deeper cut might be desired.
I had the same problem...sometimes you have to take the smallest amount off (1/64th) and it might work, otherwise your blades are probably dull. Try to feed the boards through the planer towards the sides, not just the center so they wear evenly across the length of the blades. They wear out very quickly, which makes this planer very frustrating. If you take the top cover off and inspect them, you'll probably see nicks in them and it's time to replace or rotate them. Each blade has two sides you can remove all the screws using the T-handle wrench from the top cover and flip them. Also, as the blades begin to wear, the planer will become louder and louder. That's another way to tell. When you install new blades notice how much quieter it is when you plane boards.
* Always wear safety glasses when you use a power planer.
* Keep blades in your planer sharp. Never remove any debris or touch the planer blade if it is plugged in.
* Always clamp wood to a sturdy surface when you use a power planer.
