Adjust the pressure to the minimum pressure when the bodies are
maintained in the working position during normal plowing.

Transfer the pres-
sure in the
change-over valve
Do not open the valve.
Never open the valve yourself. Opened valves are difficult to remount,
and dirt may intrude in the valve. This may lead to damage. Opening
of the valve must only be done by trained service personnel
For safe rotating of the plow, the supplied pressure must be at least
160 bar (2320.6 psi). It is recommended that the oil flow be between
25 and 35 l/min. (6.6 and 9.2 gallons/min.)
The change-over valve controls the direction of the oil flow to the turn
-
over cylinder. In certain cases the switch pressure must be adjusted.
.
Adjusting the valve pressure
> Loosen the locking nut
> Turn the adjustment bolt
> Tighten the locking nut again
Problem
Possible solution
Turn the adjustment bolt
The plow rotates halfway and goes back to
the original position.
Increase the valve pressure.
Clockwise (1 whole turn = 5 bar/
72.519 psi)
The plow rotates halfway and stops
Reduce the valve pressure
Anticlockwise (1 whole turn = 5 bar/
72.519 psi)
