Sorry to bring this back from the dead....Did you ever figure out the laggy transition from forward to reverse? Also is it slow to come to a stop? I'm wondering if my cheap AW46 Hydraulic fluid is the problem....Bringing this back from the dead so hopefully it helps someone else. I fixed my issue. Turns out the pressure relief button on the top of the quick disconnect manifold block was stuck in the down position. I had to unscrew it and tap the bottom of it against the machine to get the plunger to retract. Took me a couple tries because it didn’t seat all the way the first time. I’m surprised how much the grapple will move with such a small gap in the valve.
I added a photo of the relief. It’s the little button thing on the very top of the block with the hex nut under it.
Anyway, thank you everyone for your help!
