I have a Ridgid R4331 planer, just got it. Ran a peace of wood through and it seems OK. Except, after completion of the planing phase the end of the wood (trailing tip) is still under the planer head. I have to manually raise the head to to pull it out. I'd thought that when the wood goes through it comes out completely. At least that's always been my experience using other brands/models. It appears as though it's a "poor feed" situation, not sure. Is there something I'm missing here or doing wrong? Is it a roller problem or setup issue? Thanks in advance for some input.
