The preselection valve is now moved to the left again and the lifting cylinders HP 25/T450
R are fully retracted. To do this both the relevant control levers allocated to the cylinders
are pushed forwards at the same time.
The two lifting cylinders are then removed from the lifting points and the load is now resting
only on the traversing system (see example illustration below).
To do this, both the switching levers for pressure relief must be actuated and the control le-
vers must be held in the end position in both directions "Extend/Retract" for three seconds
(see also control table operating instructions). When the pressure in the hoses is released
you will hear a hissing noise. The pressure in the hoses dissipates and the pressure gaug-
es indicate 0 bar.
Both pairs of hoses are decoupled at the cylinders HP25/T450 R and connected to the
DUO traversing unit. The two switching levers for pressure release are moved to the start
position again.
The pair of hoses that is connected at the valve of the control lever with the red ball end ids
directed to the locking pin/anchor cylinder.
The other pair of hoses is coupled to the traversing cylinder (see illustration Page 15). Both
connections cannot be mixed up because only nipples can be connected to sleeves and
sleeves to nipples.

(Valves) for pressure
relief for trouble-free
hose exchange
Position I = pressure
Position O = non-
pressure
ATTENTION!
The operating pressure in the system must be dissipated before uncoupling
the hoses.
Even after having
switched the pressure
relief valve to position
“O”, cylinders can move
in or out (lower/lift).
ATTENTION!
