Angling of Air and Spray Liquid - Rules of Thumb

To control wind drift, the influence of wind speed and wind direction, as well as the horizontal air current around the boom
due to forward speed must be minimized. Because it is a sum of two forces with variable direction and size that we have to
counteract for, the following can only be very rough guidelines.
Angling of Air System
The air system can be angled to counteract for the wind direction and
high driving speeds.
Angling the air system forwards: Up to 40°.
Angling the air system backwards: Up to 30°.
No angling (neutral setting): 0° = the spray nozzles points vertically
towards the ground.
The angle between the spray nozzles (A) and air channel (B) is fixed.
Wind Direction
• Head wind: Angle the air stream forward.
• Tail wind: Angle the air stream backwards (if the forward speed is
higher than the wind speed: angle forward).
• Side wind/no wind: Angle the air stream vertically or backwards.
Only high driving speeds may require forward angling.
