Control Of Selective Control Valve - Zetor PROXIMA PLUS 8541 Operator's Manual

CONTROL OF SELECTIVE CONTROL VALVE

Each control lever of sections has four positions.
Lever position
1 Rear (upper) position
2 Middle position
3 Front (lower) position
4 Front margin position
Note: The lever returns automatically from positions (1) and (3) into neutral.
Remember to connect the single-acting cylinder always to quick couplings
"4", "6"!
HYDRAULIC SYSTEM
Function
Pressure oil flows to quick couplings: "4", "6"
Quick couplings connected with return line: "3", "5"
Neutral
Pressure oil flows to quick couplings: "3", "5"
Quick couplings connected with return line: "4", "6"
By increased force, it is possible to move the control
lever from position (3) forward to position (4), so
called floating (free) position, in which both levers are
locked. Both quick couplings of each section are
connected with return line in this position.
