Damping of Boom Folding Speed
Selecting the Speed
The folding cylinders can be adjusted to dampen the speed of folding / unfolding, when the cylinder piston approaches its
end stop at extension or retraction.
• If the folding is too fast, the boom sections will hit each other hard, resulting in unnecessary damage to the boom parts.
• A very slow folding / unfolding of the boom, however, will be time consuming.
The speed of folding / unfolding the boom is an individual decision, which also depends on the tractor capacity.
The speed is adjusted from the factory, but can be re-adjusted once your tractor and sprayer are connected.

Adjusting The Speed
The folding cylinders have throttles, which can be adjusted to increase or decrease the boom folding speed.
Approximately 2 inches (50 mm) of the piston stroke is adjustable in both ends.
1. Turn the Allen bolts to throttle the oil flow for adjusting the folding speed. The jam nuts are adjusted accordingly.
Only small adjustments of the throttles are required!
• Slower speed - turn throttle clockwise.
• Faster speed - turn throttle anticlockwise.
The two throttles on each hydraulic cylinder work independently, so that folding / unfolding of the boom can be
adjusted separately.
2. After adjustment, fold/unfold the boom and check that the desired speed is achieved.
3. If not, adjust the throttles again.
