Hello all.. I have a new to me cat 262d serial # DTB03788. While using it the other day I had a couple warning lights come on. My questions are with the display I have is there a way to retrieve codes? And if not what are some things I could check with those two warning lights on? The lights do not flash and do not have an audible alarm. There seems to be no difference in the operation of the machine. Also based on the serial number is this a high flow machine ? Thanks!!
