I have a 2008 Komatsu PC78 u s-6 excavator that started giving me a problem It will occasionally lug the engine
when using the swing function or bucket curl function. Today it stalled the engine once. Any help or suggestions would be greatly appreciated. The cost of having our Komatsu service guy out is astronomical !
