Connecting system tools
The system tools are connected to the hydraulic control unit by means of the control line (1) and the
hydraulic hose (2), using the quick-action coupling.
Connecting the hydraulic line
Quick-action coupling
Coupling-up
Hold the coupling socket (KM) up to the sliding
sleeve (SH), and slide it onto the coupling plug (KS).
Uncoupling
Hold the coupling socket (KM) at the sliding sleeve
(SH) and pull it of the coupling plug (KS).
Note:
- When changing the system tools, a small amount of oil will remain between the
back-pressure valves of the coupling.
- Handle the hydraulic hose with care. Bends at the connection points will lead to
premature breakdown. When coupling up, make sure that dirt does not penetrates the
coupling.
- Before coupling up another system tool, wipe out the coupling socket with a clean cloth -
that is free of fluff.
- The system tools should, as far as possible, remain coupled up at all times.
