(pressure
coupling "1")
End of lifting Lever is shifted to
position "b" – neutral
Lowering Lever is shifted to
position "c" – floating
End of lowering Lever is shifted to
position "b" – neutral

The outer circuit control lever
must be moved as quickly as
possible over position „c" (floating
position) when working
double-acting cylinder, because
both sides of cylinder
connected with the return line
and it means that uncontrolled
movement of the piston rod might
occur.
