Copy that. As for the hydraulic couplers, if the ones that you are using are a slightly larger version of standard flat face couplers, in my experience with hammers, you need to get rid of them. The pulses of a hammer will brinell the balls and grooves in the couplers, and they will also cause the couplers to come apart inside from the pules and shock of a hammer sending metal, not just fragments, but full size pieces of metal back to your machine. I've had this happen on smaller excavators with hammers, like Bobcat machine size excavators. I started using Stucchi VEP series couplers, never had another issue with hammer damage to couplers after making that change, and they will make and break with residual pressure. Only problem that I never came up with a good solution with using VEP couplers is, since they screw together, the vibrations of a hammer will cause them to un-screw. Simple fix is wrap Gorilla duct tape around the coupler once fitted to keep it from unscrewing, but I always wanted to come up with a better fix. But even with that quirk, the VEPHD couplers are far better than typical flat face couplers when using a breaker. > https://www.stucchiusa.com/products/threaded-flat-face-couplers/vephd-series/
