With increased effort, it is possible to shift the control levers
from the position (3) forwards to the position (4) called floa-

“ 2 “, “ 4 “, “ 6 “ at three-section SCV
Double-acting cylinder must be connected to the quick couplers of the same
section (it means
:” 1 - 2 ”; :” 3 - 4 ”; ” 5 - 6 ”)
The first (right) section of SCV is
equipped with hydraulic lock in pressure
positions.
