Relief Valves    Pressure change With One Turn Of Adjustment Screw    
Main valves    
14400 kPa (2100 psi)    
Line relief valve    
11000 kPa (1600 psi)    
Swing relief valve    
6800 kPa (985 psi)    
Pilot relief valve    
620 kPa (90 psi)    Note: Pressure values in Table 5 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 Pressure - Purge".
