Hey hef I got one of them can you fix my machine but I can't stop running it and it doesn't always act up kinda jobs and I'm hoping for some advice.
Machine was digging for a few hours no complaints operator says all functions stop he cycles safety lever few times and it starts working. Now when machine swings it interment stops then will swing again after a few minutes pause or by bumping another control. over the past two days it will do this on stick,boom, or travel only seems to act up on one fuction at a time .but if you change direction and retry function it will work. it seems to be worse as the day goes on when a function doest work the whole pilot pressure system drops to around 200 psi and doesn't recover until another functions is activated or original function is reversed. Any thoughts welcome this is the first time I'm working on Komatsu hydraulics and theory and terminology is a little different from my previous experience
