Filling and venting of hydraulic system
Installation
– continued –
To fill the whole hydraulic system of the loading system carry out the following two steps:
. Filling the hydraulic actuator system
Sequence: Both sides separately one after the other.
2. Filling the hydraulic indicating system
Sequence: . Liquid phase
2. Gas phase
The hydraulic system has to be filled after installing the loading system or when maintenance work or repairs have
been carried out.
Attention
Use only oils that are recommended by the manufacturer. Recommended oils are ESSO Zerice 22,
ARAL Vitamol 4004 or other oils with similar properties.

. Release the tension rope - the ball valve
of the control unit X of the bottom valve HWV 25/ - DN 80
will automatically open the hydraulic system.
2. Unscrew the red plug S and the dip stick of the oil filling connection of the hydraulic hand pump T
and fill oil into the tank.
3. Pull the tension rope in order to close the ball valve of the control unit X of the bottom valve
HWV 25/ - DN 80.
4. Operate the hydraulic hand pump T until the resistance first increases perceptibly, the pressure limiting valve
responses audibly and then there is a distinct pressure relief. Then carry out 20 to 30 strokes with the pump
lever F of the hydraulic hand pump T in order to discharge the air in the hydraulic system via the pressure-
limiting valve.
5. Use the oil dip stick S in the cover to check the oil level. If necessary refill oil and screw in plug S of oil filling
connection with a torque of 20 Nm.
6. Finally loosen the tension rope in order to re-open the hydraulic system.
Repeat the whole procedure with the second hydraulic hand pump
T.
