The hose lines are connected via quick-disconnect coupling halves (female and male) to the
hydraulic pump in such a way that they cannot be reversed.
Before connecting the couplings, remove the dust cap, then pull back and hold the locking
sleeve of the female coupling (Position X). Push the male and female couplings together and
release the locking sleeve. Finally, turn the locking sleeve into Position Y. The connection is
then made and secured. Decoupling is done in the reverse sequence.
WARNING / CAUTION / ATTENTION!
The quick-disconnect-couplings have special functions, in part, and therefore
must not be unscrewed and/or reversed!

For dust protection, the supplied dust caps must be reattached.
NOTE:
Coupling the equipment is only possible if the hoses are depressurised.
