System operation

5.1.1 General
Oil is drawn under the pump plunger out the oil tank by moving the pump lever upwards and oil is
pressed into the hose system by moving the pump handle downwards.
In two-stage pumps a change over valve ensures that the oil flow is automatically reduced when change
over pressure is reached. Every pump is fitted with a safety valve, which limits the maximum pressure.
5.1.2 CORE™ couplers
The hydraulic hose of the CORE™ system is a single hose, that combines a high pressure supply hose
inside a low pressure return hose. The female coupler has a unique function: after disconnection it
connects the supply and the return lines internally. This means you can connect and disconnect tools
without interrupting the oil supply to the hose.
