Hydraulic Connections
Our hydraulic pumps are equipped with a zero-pressure relief valve. However, it could be possible that the retract side remain pressurized after the pump has been switched “off”. This trapped pressure prevents the user from loosening the retract-side fittings by hand. To release the pressure, simply push the black button on top of the solenoid. All fittings are free to be manually tightened.
Never disconnect or connect any hydraulic hoses or fittings without first unloading the wrench and the pump. If the system includes a gauge, double check the gauge to assure pressure has been released. When making connections with quick disconnect couplings, make sure the couplings are fully engaged. Threaded connections such as fittings, gauges etc. must be clean and securely tightened and leak free.
WARNINGLoose or improper threaded fittings can be potentially dangerous if pressurized. Severe over tightening can cause premature thread failure. Fittings need to be only tightened secure & leak free. Never grab, touch or in any way, come in contact with a hydraulic pressure leak. Escaping oil can penetrate the skin and cause injury.
