Check the pressure gage to confirm a hydraulic load on the auxiliary pump of 2000 ± 50 psi (13,790 ± 345 kPa). Ifnecessary,
adjust the system selector valve relief valve with the adjusting screw to obtain a pressure reading of 2000 ± 50 psi (13,790 ±
345 kPa). Check engine rpm for 2000 ± 100 rpm. If engine rpm is below 2000 ± 100 rpm, troubleshoot.
