Any information for a new owner of Hitachi ex60 urg I purchased this machine and I'm having a issue. And any info would be very much appreciated. The bucket hydraulic moves very slowly until I activate another hydraulic at the same time. And I believe my other problem could be in result to the same issue with my machine. When propelling the machine in any direction I can not move the left track by itself but ounce I move the the right track then at that point I can control the other track at the same time. It seems to me that I have a lack of hydraulic pressure of some sort. I was told it could be a hydraulic pump issue and to drain my hydraulic reservoir and check for any contamination at bottom of tank ( which I have done and have not found any visible contamination ) Has anyone had this issue or any insight on it would be greatly appreciated
