Selector valve operation
Optima 500 – 700. When the machine is commissioned,
ensure that the selector valve lever is moving without
obstructions.
The movement is checked by lowering the harrow
approximately 50 mm down from the transport position
and moving the actuator arm back and forth.
The locknut at the end of the thread of the actuator arm
must be adjusted so that there is a clearance of a few
millimetres in the actuator arm when the harrow is at
the top transport position.
The spring in the actuator arm of the selector (point 3)
can compress. The valve has a limiter against which the
valve spindle stops in the harrow working position.
The bolt 5 must not be tightened too much. You should be able to rotate the bolt by hand.
