7.2 Quick-disconnect couplings
7.3 Screwed joint couplings
7.4 Direct connection into the valve block
1. Remove the dust protection caps,
2. Connect the female coupling of the hose with the male coupling of the pump,
3. Screw the threaded sleeve or the female coupling onto the external thread of the coupling
male and tighten them with a torque of 40 Nm.
1. Remove the closing screw from the port “B”.
2. Screw the appropriate hose line / coupling directly into the valve block and tighten it with
a torque of 45 Nm.
3. Remove the closing screw from the port “A”
4. Screw the appropriate hose line / coupling directly into the valve block and tighten it with
a torque of 45 Nm.
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 reversed!
For dust protection, the supplied dust caps must be reattached.
NOTE:
Coupling the equipment is only possible if the hoses are depressurised.
ATTENTION!
Always connect the return line first and then the supply line!
