When it first happened I called Schwing and I was told if it would not pressure up then the pump was shot.

your main pressure relief should be set to 2900psi, standby pressure for your pump is 200psi, and pressure cutout for the pump is set to 2500psi. be sure to set the accumulator gas pressure to 400psi.  I can email you the complete schematic, send me a PM
