Well, I just purchased my first planer on CL for $120. It’s a 12” Jet. Looked like a great, but now maybe not. I tested it out at the guys house on some 1x oak and planed the piece nice and smooth. Well, when I brought it home to run some more test piecesof pine through it, I noticed that little scrapes and dents were in the wood. I figured I just needed some new blades. well, I bought some new blades and there is no difference . Still nicks and dings in the wood.What gives????? The only other thing I can think of is that the roller that has the blades in it, has some surface rust?? Maybe thats it? What do you LJ’S think the problem is???

Is this happening in one area or all over the planer. If you plane a board straight through you can kind of tell where the problem is by looking at the board when it come out. Mark the planer with a pencil where the scratches are so you can reference where to start looking for a problem, if that makes sense. I would give her a good thorough cleaning. Look at the rollers, clean them off and see if there is a problem somewhere on it. Check to make sure if there is anything hanging down. Look at where the blades are and make sure there is nothing that the blades might be hitting and getting dinged. In my experience if the blade has a ding in it, it will leave a raised mark on the wood all the way down the wood, not a nick or a ding.

I suspect you have debris on the rollers.

Look at the grain direction of the wood you’re planing. If you plane
“uphill” you’ll often get chipping.

You might also not be clearing chips well enough. When I plane without dust collection turned on (by accident, plug the wrong hose in, etc) I get dents and dings. I suspect chips are getting caught between blade and wood, and get smashed into the wood. I would expect pine to be more susceptible to this than oak.

Feed rollers are dirty.

the marks are all over the board, not in one area. i dont have a dust collection yet. so maybe the chips getting caught inside is the problem. i will also check the feed rollers.

I agree with all the previous posts, but also add that a piece is rarely “finish” ready when it comes out of the surface planer. I also get this a lot in pine, more so than hardwoods.

Since you got it figured out, this might not help much, but to summarize this…

#1. Make sure you are collecting the dust / chips from this. That stuff gets between the wood and the cutter and makes a mess of things. #2. Make sure your feeding with the grain, and not against so that you don’t chunk out the grain with the cutter head. See Marc Spagnolo’s The Jointer’s Jumpin video for tips on that. Yeah jointing and planing have a LOT of the same issues…
