Night Spraying Light
The night spraying light is activated on the controller box in the tractor. Press the A and B switches in the lower left corner.
If traffic lights are fitted, the work lights will only work when the traffic light is on.
Settings for TWIN air system:
Watch the controller display when pressing the buttons.
The current air angle is shown as a percentage 0 - 100 %.
0 - 49 %: The air system is angled forwards ( 0 % = 40° ).
50 %: The air system is in default position with the spray nozzles pointing vertically downwards.
51 - 100 %: The air system is angled backwards ( 100 % = 30° ).
The current air speed is shown as a percentage 0 - 100 % and/or as revolutions (rpm) for the blower impeller. A value of 100 % equals
3100 rpm for the blower, if the tractor’s PTO speed is set at 1000 rpm.
A lower PTO speed = a lower blower speed.
One short press on the button changes the current value in steps of approx. 5 %.
Holding the button will make a greater and stepless change.
Button lower left: Adjust the air angle forwards.
Button lower right: Adjust the air angle backwards.
Button middle top: Increase air speed.
Button middle bottom: Decrease air speed. If you spray with the boom 1/2-folded, reduce the air speed with 25 % to obtain the same
performance (air speed at nozzles) as for a fully unfolded boom.
Press the buttons 1 or 2 to use preset values for air speed and angle. Changing between 1 and 2 is usually done while turning at
headlands to spray in the opposite direction. To save a new setting, adjust the air speed and angle, and press 1 or 2 for at least 8 seconds,
until the controller display signals the change (if you press the button for less than 8 seconds, the previous saved setting will be in use).
SafeTrack:
This is mainly used when making turns in the field.
Press “auto” for automatic adjustment of the sprayer tracking, making it follow the tracks of the tractor’s rear wheels.
Press left or right arrow to manually adjust the sprayer tracking
.
Press double arrow to lock the sprayer tracking (the hydraulics will adjust the sprayer to its center position, and a mechanical lock will be
activated at the rear). This is always done before folding of the boom.
Optional functions, A or B.
E.g. for night spraying light on the boom:
A: Turn lights on; B: Turn lights off.
If traffic lights are installed, the work lights will only work, when the traffic lights are turned on.
Press “auto” to use an optional function.
