Drawing see page 4
1. To close the bottom valves disengage the rail hook from the rail. This results in
the tension rope being loosened. The ball valve of the control unit opens the
hydraulic system and both rapid-action bottom valves will be closed
instantaneously. Be sure that both bottom valves are closed by checking the
indicating pistons of the indicating cylinder . Both indicating pistons must be
retracted.
2. Then close and latch the operating device .
3. To finish the loading/unloading process close the shut-off valves and attach
sealing plugs to shut-off valves .

Attention
Note: If the lid cannot be closed, one or both bottom valves are still open!
The inside of the lid of the operating device features a bracket. This
bracket prevents the closing of the lid when one or both bottom valves are
open. The lid can only be closed when the indicating pistons are retracted.
The cause of this malfunction must be ascertained and eliminated!
If only one operating device for the loading system was opened, the lid of
the other operating device cannot be opened when the bottom valves are
open.
