Return to Master Table of Contents Compare recorded values with output shown in the P-Q curve in the specifications section of this book. If test results do not measure up to specified values, pump output tests can be repeated using different control levers. Recheck front pump operation while stroking the bucket cylinder out lever, and the rear pump by actuating the swing control lever. NOTE: When testing bucket and swing functions, read maximum flow tests at 320 kg/cm 2 (4,550 psi), not 350.0 kg/cm 2 (4,978 psi). Page 21 Hydraulic System Troubleshooting, Testing and Adjustment
