I consistently get a front roller compression error when I crank down the head (switch remains "released"). I find that if I push down lightly on the head after it contacts the wood and continue to crank, I can get the front switch to show compressed and then everything works fine. I measured head force with a scale and I measure only about 68 pounds before the clutch disengages. I've cleaned and lubed the shafts with no improvement.
I think the problem is that the handle clutch disengages too soon, before I've built up enough compression to trip the switch. I was wondering if it's possible to adjust the clutch to get more compression before it releases?
