9.3.3 Mono-couplings
The mono-couplings must be replaced in the event of:
- external visible damage,
- the locking device not working,
- hydraulic fl uid continually leaking in a coupled/uncoupled state.
Procedure:
1. Remove the cover from the couplings.
2. Loosen the connection nuts of the hose assembly and remove the coupling.
3. Position the new coupling and tighten the connection nuts of the hose assemblies
with a torque of M
A
= 40 Nm/29.5 lbf∙ft and push the cover of the couplings back on.
WARNING / CAUTION!
Never repair couplings: they are to be replaced by original LUKAS parts!
CAUTION!
Take care that the port ‘T’ / ‘T1’ of the hose reel is always connected to the port
‘T’ of the mono-coupling.
