In this video I show how I checked my main pressure valve pressure on my AGT QH12R. A long time ago I had purchased a cheap hydraulic pressure gauge that goes up to 5,000psi. I messed up the thread size on it so I had to get a reducer and a special fitting that went from Female NPT to DIN Light M16x1.5mm Male. I used my auxillary line so I didn't have to disconnect the boom or dipper to test my pressure. To my surprise it was adjusted perfectly from factory so that just goes to show that some machines are well built and others can be lemons. I was glad I didn't have to adjust it but it wouldn't hurt to know how to do it. I have a few affiliate links below if you need some parts.
Please be sure to double check links in case amazon ever changes them.
