A friend gave me his Hitachi planer when he upgraded to a new one. I planed a few test pieces and it worked great. So it has been sitting patiently in the corner for about 6 months waiting for me to use it. I scoot it out, crank it up and it will not pull the boards through… just leaves little skid marks in a few spots on the boards. I tried cleaning the rollers a bit with alcohol and played with setting the height at different settings and never could get it to pull the wood smoothly through. I finally just gave up and used a full thickness board for the project. I have never owned a planer and I am not sure exactly what the problem is and what I should be cleaning. I crank it all the way up and I can see a roller on either side of the blades. What should I be cleaning and how or with what? It worked quite well when I first got it home!

If you have cleaned the feed rolls and waxed the platen you need to take a look at the drives.
It may be that one of the gears is cracked/broken. It is fairly easy to remove the cover on the drive end and take a look at them.
I have had mine work fine one board and quit the next because of the gear.

With the marks (I would guess that they are slipping, making the skid marks) I would tend to believe that prior cleaning with the wrong cleaner and age may have caused them to harden.
Try running it with the head raised as high as you can get it and watch the feed rolls, keeping an eye out for uneven rotation and with the planer off feel the rolls, they should be firm but not rock hard and “sticky” but not soft and sticky!
I use plain water and a little soap, alcohol can harden the rubber and actually make it harder for them to feed the material.
I hope that helps, and I am sure someone will be able to give more advice soon!
