Ensure that when connecting Quick Release Couplings, the low-pressure line is always correctly fitted before fitting the high-pressure line. When disconnecting hydraulic tubing and hoses, always ensure that no hydraulic pressure has been retained in the line after the power supply to the system has been switched off. Operate the manual levers on the valve bank to relieve any residual hydraulic pressure. Refer to Precautions with Over-Centre Valves and Check Valves. |
