LEVERS
Lever position Function

Quick couplers connected to the discharge :”1”, ”3”, ”5”
2
Middle position
Neutral
3
Front (lower)

position
With increased effort, it is possible to shift the control levers
from the position (3) forwards to the position (4) called floa-
ting (free) one, where the levers are arrested. The two quick
couplers of each of the section are connected to the dis-
charge in this position.
Single-acting cylinder shall always be connected to the quick couplers:
“4“, “6“ at two-section SCV!
“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.
A - At two-section SCV this is a section
of quick-couplers “3“ and “4“.
B - At three-section SCV this is a sec-
tion of quick-couplers “1“ and “2“.
The outlet „4“(A) or “2” (B) in addition, is
fitted with a check valve – to be used for
the connection of machine operating
branch with increased sealing parame-
ters - minimum descent of implements in
the course of transportation, for instan-
ce.
Note:
The lever automatically returns
from the position (1) and (3) to the neut-
ral one.
