Rotating system
The plow will not start reversing
The connections to the tractor have
been installed incorrectly.
Ensure that the quick connections
have been correctly connected
(see the colour coding on the hos

es)
The plow will not start reversing –
the plow reacts with an abrupt start
only when the oil pressure to the
change-over valve is increased
The valve pressure is wrong
Increase the valve pressure by
turning the change-over valve
clockwise a couple of turns (see
»Transfer the pressure in the
change-over valve« on page 73)
The plow turns halfway and stops,
or goes back to the original position.
The restrictor regulation is installed
on the wrong port
Change the restrictor position (see
restrictor position, page 67)
The valve pressure is wrong

The transfer is taking place too early,
shortly before the dead point is
reached

Vibration during rotation
The restrictor is installed on the wrong
port
Change the restrictor position, see
»Restrictor position«, page 67
Rotation takes place more slowly on
heavy plows and is possibly not
completed.
Problem with the oil flow
Test to see whether different oil flow
speeds affect the rotation by adjust

ing the engine speed or the flow
speed of the motor-operated valve;
change-over valves operate opti

mally with 25–35 l/min (6.6-9.2
gpm). High flow speeds can return
pressure and cause weaker rotat
