To insert the threaded lifting pins, the operator must keep the push element pressed. This
causes the threaded elements to be retracted via the push pin. The operator can now
insert the threaded lifting pins into the nut thread and then release the push element. The
push element and the push pin are reset by the spring and the threaded elements are
pushed out again. The threaded lifting pin must then be fully screwed in by the operator.
To release, the operator must first turn the threaded lifting pins slightly out of the nut
thread (approx. ¼ turn). Subsequently, by pressing and holding the push element, he can
retract the threaded elements and take the threaded lifting pins out of the nut thread. The
push element can then be released again.
