Before coupling, remove the dust protection covers and unlock the connect socket with adjusting
ring by turning it. Withdraw the sleeve and connect plug and socket while holding the sleeve in
this position. Release the sleeve and set the showglass to „red“ with the adjusting ring. Now the
parts are connected and locked. Decoupling is done in the reverse order.
Note regarding the modified release mechanism as of June 2004
When connecting the hoses, be aware of the following basic functions of the quick couplers:
Before coupling unlock the connect socket by turning the sleeve into position X. Retract sleeve
and connect plug and socket. Release sleeve and turn it into position Y.
Now the connection has been made and locked. Uncoupling is done in the reverse order.
Connection of the hoses is possible only, when they are depressurized.
In order to prevent contamination of the tool lines protect the couplings with delivered dust caps.
Attention!
Quick couplers partly have special functions. Therefore it is not allowed screwing them off
from the hoses or to exchange them.
