5.3 Coupling Quick-disconnect Couplings
The device is connected to the hose lines to the hydraulic pump using non-interchangeable
quick disconnect coupling halves (female and male coupling).
Before coupling, remove the dust caps then pull back and hold the locking sleeve on the
female connector (position X). Plug the male and female connectors together and release the
locking sleeve. Then turn the locking sleeve to position Y. The connection is then made and
secured. Decoupling is done in the reverse sequence.
WARNING / CAUTION!
To some extent the quick-disconnect couplings have special functions and may
therefore not be unscrewed from the hydraulic lines and/or swapped!

For dust protection, the supplied dust caps must be reattached.
NOTE:
Hoses can be connected only when depressurised.
CAUTION!
Always connect the return hose first and then the supply hose!
