We had a rough day today. One of our operators flipped our cat 303 mini excavator. He was able to get it upright using the boom and stick however, once the machine became upright the hydraulics stopped. I checked for pinched hoses, broken wires, the safety switch, all the fuses and even took off the battery cables to see if the computer would reset. It's funny because the machine still starts and runs and everything is okay (except for the lower bumper) it's just the hydraulic system that is not working. Any other quick fixes before I call the dealer?
