Hello, I'm still having problems with this unit .The initial problem was that I had absolutely no hydraulics . Technician diagnosed this as a bad pump. After having the pumps inspected and rebuilt , still no hydraulics . Technician then diagnosed it as bad coil/ solenoid on the main manifold , wire broken off. Replaced Coil . Now we have drive forward and back and boom swing , but the blade won't go up and the slew and bucket are very slow and only seems to work at high Rpm . Also, if you apply the rabbit while moving, it doesn't seem to go faster .If you activate the aux hydraulics and hold it on and apply the blade the blade goes up. Any ideas what could be going on ?
