Line relief valve (blade)    
15680 kPa (2275 psi)    Note: Pressure values in Table 6 are approximate values. Use a pressure gauge for adjustment.Note: Normal operations of the engine and pumps are necessary for the pressure adjustments. If the results of the pressure adjustment are not correct, then the engine and the pump characteristic curve needs to be checked. Slow output flow from the pump is an indication of air in the hydraulic system. Make sure that no air is present in the hydraulic system. Refer to Testing And Adjusting, "Main Hydraulic Pump Air - Purge".
