6.3 Monocouplings
Male coupling
Female coupling
Dust caps
Before coupling, remove dust caps, then connect male and female couplings and turn locking
sleeve of the female coupling in direction "1" until the locking sleeve latches. The connection
is then made and secured. The decoupling is accomplished by turning the locking sleeve in
direction "0".
The coupling of the devices under pressure is also possible, assuming the connected
equipment is not turned on.
NOTE:
We recommend, when ambient temperatures are low and extension hoses
are used, connecting the coupling halves in a depressurised state because
decoupling may otherwise require a very large exertion of force.
For dust protection, the supplied dust caps must be reattached.
WARNING / CAUTION / ATTENTION!
The monocouplings must not be unscrewed and/or the hose lines reversed!
The hose lines are connected via monocoupling halves (female and male) to the hydraulic
pump in such a way that they cannot be reversed.
