Hello all. My name is Jon, I'm new to the forum. I have a question that I'm hoping to get some guidance on. I've just installed a gentec 830 hydraulic thumb attachment on my 2004 JCB 8027 excavator. The manufacturer recommends setting the auxiliary relief pressure to 1800 psi to protect and ram. I have a manual but it doesn't mention anything about how to set/reduce the pressure for the aux system. The thumb is installed and working great but I would like to test and adjust the psi to be safe. Thank you in advance.
Is it adjusted by setting the right track Main relief valve MRV to 1800psi? Its originally set at 3000 plus psi.
