5.1 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 tool.
The double-acting tool has a hydraulic cylinder containing a piston that can move axially. If the cylinder
is pumped full from the bottom, pressure builds up beneath the piston so that it is pushed to the outside.
If the cylinder is pumped full from the top, the piston is forced back into the cylinder. In tools like cutters
the axial movement of the piston starts a mechanism that makes a cutting or spreading movement.
The direction of the movement of the piston is determined by the position of the control valve on the
pump. The control valve on the pump is controlled by push buttons on the tool.
The hose is the piece of equipment that connects the pump to the tool, thus creating a closed system.
5.1.2 Quick-lock couplers
The tool is equipped with a male and a female Quick-lock coupler. Quick-lock couplers are pushed into
each other and then lock.
