OK- probably will seem like a stupid question. But here goes. I have a new Cat 307E2, Ser KC900982. Equipped from dealer with hyd quick coupler, and hydraulic thumb. When I received the machine, the thumb bottomed out in the bucket. After I mentioned thinking this wasn't correct, they changed the thumb to a longer one that does extend just past buckets' cutting edge. A handy device now.
Question about relief pressure on thumb. It seems from my reading here over the years, that it is customary that the bucket curl will roll the thumb up as well. Mine usually won't. But nowhere in the manual can I find any reference to it or how to change it. Nothing in the electronics about an adjustment. Asking the sales person didn't get me a definite answer either.
A) Should bucket roll the thumb up?
B) If yes- how do I adjust the pressure relief to allow this?
