Hello,

I have a DW733 and recently it started leaving two lines on the boards as
they passed through the planer. I changed knifes and still the same result.
The lines look like someone took a utility knife and scored the board length
wise. The lines are on the top of the board as it comes out of the planer.
They are about 3 inches in from either side of the planer.

I looked and felt underneath were the rollers and knifes are but could not
see or feel anything sharp.

Any one have this happen before?

Are the lines raised or are they depressions? Raised usually means that there is a chip in the knives from hitting something hard.
Depressions are usually caused by something in the bed.

The lines are depressions, like a knife score. And they are on the top of
the board opposite the side that touches the bed.

Mine leaves lines exactly as you describe, only on mine they are raised. It
took a close look to determine that they were raised the first time I saw
them, but they are in fact raised and sand or scrape off easily. As
someone else posted, this is caused by chips in the blade. I don't know
what could be causing recessed lines.

Becha you got NICKs in a couple of the blades

You might be able to get a bit more life out of those blades before
replacement or sharpening by shifting the blades a bit to offset the
nicks.

I changed blades and the lines are in the same place.

Works when they leave a protrusion, but he has indents.

If they are depressions, then you have some crude sticking down and
gouging the wood from somewhere in the path the wood is taking

Run a really nice, smooth piece of wood thru with the blades/cutter
head adjusted to it doesn't touch the wood. If no depressed
line/groove/etc in that situation, then the problem is in the cutter
head and I would pull the cutter head and give a good going over for
some contaminant stuck on and doing this

You can't shift the blades on the 733.

That is incorrect. At least for the 733.

This is correct.

I have the same problem. It appears to be the heads of the bolts holding the
blades. You can see shiny spots on the bolt heads where they have hit the
wood. Anyone know if Dewalt has fixed the problem? It would take bolts with a
different sized head to fix.

New blades? Are your blades worn enough that the heads are exposed?

Since the original thread was from 2004, I gotta ask:

Have you been putting up with the lines on your board for 14 years waiting
for Dewalt to fix the problem?
