Good day! I have a pc200-7 that smokes when i move the control lever/joystick fast. And i tested some of the pressure measurement plugs and found out i got no pressure at PC-EPC output pressure, in the shop manual when in idle you can get 30kg/cm2 which is about 427 psi. By the way i just bought the excavator secondhand. And when it arrive Ls valve rear and front is not the same so i correct it. Will this be the PC VALVE ALSO not correctly adjusted? Hope someone can help me with this. Thanks a lot.
Make sure the electrical system is in good condition first
