Connect The Hydraulic Hose(S) - Holmatro SP 52 Serie Betriebsanleitung

EN
The hose is the piece of equipment that connects the pump to the tool, thus creating a closed system.
The tool has a return line safety valve. If the return line to the pump is blocked, this return line safety
valve will prevent excessive pressure in the tool by allowing oil to leak out.
5.2 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.
