This page provides answers to frequently asked questions regarding; troubleshooting basic hydraulic systems, basic installation/plumbing diagrams, basics on functionality of our control valves (manual and solenoid operated) and directions for identifying our products. Troubleshooting Basics

1) All hydraulic valves must be properly installed into the hydraulic system to prevent personal injury and/or property damage. Further, the improper servicing of a valve may result in personal injury and/or property damage. Please read and understand all catalog and service information before starting. As with all mechanical work the proper tools, knowledge, and safety equipment are required. Always wear safety glasses.
2) Make sure all pressure has been relieved in the hydraulic lines before installing or servicing a hydraulic valve. Warning: escaping hydraulic fluid under pressure can have sufficient force to penetrate skin, causing serious personal injury. Do not use your hand to check for hydraulic leaks.
3) Before installing or servicing a hydraulic component make sure all weight has been removed from the cylinders or motors before disconnecting hydraulic lines. Warning: disconnecting the hydraulic lines while the cylinder or motor is under load may result in the unexpected rapid movement of machine resulting in serious personal injury.
4) DO NOT exceed the operating specifications for pressure, flow or temperature. All hydraulic systems require a means to limit the maximum pressure. This requires either a pressure relief valve in the system or a pump that has pressure compensation. Warning: overpressure may cause sudden and unexpected failure of a component in the hydraulic system resulting in serious personal injury. Always use a gauge when adjusting a relief valve.
