I bought a PM 15HH planer a couple of years ago (still under warranty). The outfeed has gradually gotten worse, even after checking/adjusting everything. I called PM and they said to drop the outfeed roller to .032 below the cutterhead, rather than the .020 as the manual stated. After doing that, and constant adjustment of the tension springs on the roller, it never got better, actually a lot worse. Ended up having to pull boards out of the machine, with horrible cut quality. I rotated the knives, just to rule that out. I called PM again, and they sent out a repairman. He had never worked on this style of planer, so after I educated him on how it all worked, he checked everything, and determined a new outfeed roller would cure the machine. A week later, he comes back, installs the new outfeed roller, and it worked better, but not like it did when I first got it. Today, I was using it, and on some of the boards, I had to pull some of the boards out. It does not matter if I take a small pass or heavy pass, same symptoms. The tables are flat/co-planer, the chip breaker is even with the bottom of the knives, and the table is waxed regularly. The tech set the table rollers app. .004 above the tables, and it did not seem to help. Does anyone who has this machine ever had the same problem, and what am I missing to correct it? Thanks.
