Disconnect The Hydraulic Hose(S); Operate The Deadman's Handle - Holmatro CC 23 Manual De Instrucciones

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.

• 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.

5.4

Operate the deadman's handle

The deadman's handle is used to determine the movement of the plunger(s). In the neutral position no
pressure is built up and the oil flows back to the pump without pressure. If the deadman's handle is
released, it returns automatically to the neutral position and stops the movement of the plunger(s).
