Low brake pressure alarm going off. Everything still works fine and doesnt go off until after running the machine for 1-2 hours. Any help would be appreciated, dont know where to start looking.
Series number 4nn00391
Too lazy to look on SIS at the moment. Does it have accumulator(s) on the brake system..? If so the precharge pressure would be the first box I’d want to be ticking.
Here is the SysOp for the brake system. It has 2 accumulators so my comments above regarding checking precharge pressure are the first place I would start checking. The specified precharge pressure with dry nitrogen is 1000psi @ 68 DegF ambient temperature. If the pressure has not been checked in a while then it is likely to be significantly below specification.
