System operation

5.1.1 General
A system is an assembly of a hydraulic pump, hose(s), and one or more tools. The hydraulic pump is
driven by an internal combustion engine, electric motor, pneumatically or by hand or foot power. This
pump displaces hydraulic oil and is capable of building up pressure. The hose is for transporting the
hydraulic oil between the pump and the equipment.
The tool has a hydraulic cylinder containing a plunger that can move axially. If the cylinder is pumped
full from the bottom, pressure builds up beneath the plunger so that it is pushed to the outside. When
the pressure from the pump is relieved, the plunger is forced back into the cylinder by the internal
spring.
The hose is the piece of equipment that connects the pump and the tool together. For rescue
applications, the hose is equipped with a single-hose couplers.
5.1.2 Single-hose couplers
The single-hose coupler is used on single hoses. Each end of the hose has a female and a male
coupler. If you want to connect or disconnect a tool and/or a hose, you must first set the pressure relief
valve on the pump to the "neutral" position. After connecting the hose and the tool you must set the
pressure relief valve to the "operation" position so you can use the tool.
