I have a DeWalt DW733 12-1/2" planer that has started having feed problems. The board will start to feed through properly but after about a foot and a half it seems to skip and jerk. For example the first two feet of a three foot board will feed through properly and then the jerking starts. It doesn't appear there is any problem with the cutter assembly.

I can't see any glazing on the feed rollers but I guess they could be sticking. From the parts diagram it looks like a major job to change the rollers even if I can figure out where to purchase new one.

Does anyone have a suggestion on how to handle this problem? Also, what is a good product to use to clean these type of rollers?
