The equipment is connected to the hydraulic pump via quick-disconnect coupling halves
(male and female).
Before coupling, remove the dust protection caps, then pull back and hold the locking sleeve
of the female coupling (position X). Connect the nipple and female coupling and let go of the
locking sleeve. To conclude, turn the locking sleeve into position Y. The connection is now in
place and secure. Uncouple in reverse order.
WARNING / DANGER / CAUTION!
Some quick-disconnect couplings have special functions. Therefore it is
not
permitted to
screw them off the hoses or to swap them!
