12.3.2 Mono-couplings
The mono-couplings on the connection hoses on the equipment must be replaced in the
event of:
- external damage
- the locking device not working
- hydraulic fluid continually leaking in a coupled/uncoupled state.
WARNING / DANGER / CAUTION!
Never repair couplings: they are to be replaced by original LUKAS parts!
Procedure when mounted on hoses:
1. Remove the cover from the couplings.
2. Loosen the union nuts of the hose assembly and remove the coupling.
3. Position the new coupling and tighten the union nuts of the hose assemblies
with a torque of M
A
= 40 Nm and push the cover of the couplings back on.
Procedure when mounted into the valve block:
1. Remove the coupling from the valve block.
2. Position the new coupling and tighten it with a torque of M
A
= 40 Nm.
CAUTION!
As the case may be, make sure that port 'T' or 'T1' of the unit is always connected
to port 'T' of the mono-coupling.
