Adjustment of Boom Folding Speed
The main hydraulic block distributes hydraulic fluid for the boom
controls.
The throttle valve (A) can adjust the folding speed of the boom.
Check the Folding Speed
•
Unfold the boom.
•
Fold the outer boom sections calmly into the transport position
without crashing hard against the other boom sections.
The folding speed is set from factory. However, it may be adjusted before
use of the sprayer if the operator finds it necessary.

ATTENTION! The throttle valve only needs slight adjustments to
change the speed significantly.

•
Risk of premature wear and tear.
