In tools like cutters, spreaders and combi tools the axial movement of the piston starts a mechanism
that makes a cutting or spreading movement.
The hose is the piece of equipment that connects the pump to the tool, thus creating a closed system.
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.
5.2 Connect the hydraulic hose(s)
5.2.1 General
CAUTION
Never use damaged couplers.
Never use pliers or similar tools to connect the hydraulic couplers.
5.2.2 Hose with CORE™ couplers
See Fig. 5.
• Remove the dust caps from the couplers.
• Check the couplers for dirt and damage and clean them if necessary.
• Insert the couplers by holding them against each other and pushing the male coupler with one
action into the female coupler. The external ring of the female coupler must move in the opposite
direction to the arrows.
• Pull both couplers to check whether the couplers cannot be pulled apart with a normal manual
effort.
• Put the dust caps into each other to avoid dirt.
NOTICE
Do not store the hose with the ends coupled together.
5.3 Disconnect the hydraulic hose(s)
5.3.1 General
CAUTION
Never use pliers or similar tools to disconnect the hydraulic couplers.
5.3.2 Hose with CORE™ couplers
See Fig. 6.
• Disconnect the dust caps from each other.
• Disconnect the couplers by turning the external ring on the female coupler and then sliding it in the
direction of the arrows. The male coupler will slip out.
• Remove dirt and oil from the couplers and dust caps.
• Replace the dust caps on the female and male couplers.
