4 - Sprayer setup

Boom
Pendulum setup
The purpose of this adjustment is to align the 4 steering arms (A) to level
position. Adjustment of the pendulum device needs to be carried out
before putting the sprayer into operation for the first time. Subsequent
adjustment will be required very seldom.
Perform adjustments with the boom unfolded.
1. Support the pendulum with e.g. a crane.
2. Remove the bolt in the bottom end of the spring arrangement and
the big nut at the upper end of arrangement.
3. Lower the pendulum until spring arrangement clears the pendu-
lum.
4. Remove the spring arrangement.
5. Fix the ends of spring arrangement. Grasp around the spring and rotate the whole spring arrangement to regulate
the length of it.
• Clockwise rotation: The spring arrangement becomes longer and the steering arms are moved downwards.
• Counterclockwise rotation: The spring arrangement becomes shorter and the steering arms are moved upwards.
Use a level to inspect the alignment to make sure the 4 steering arms are level. When correct position is obtained:
1. Refit the spring arrangement and tighten the big nut at the upper end of arrangement.
2. Extra check that the spring arrangement is correctly refitted and then release support from pendulum.
Pendulum effect adjustment
The pendulum effect can be adjusted to match the local topography.
For this purpose, the 2 bottom steering arms can be fastened in 3
different positions.
• Always use the same position for both bottom steering arms.
• Always perform adjustments with the boom unfolded.
Position Behavior
1 The boom is free and will optimize suspension towards horizontal.
Use when spraying flat country.
2 The boom follows the movements of the trailer to some extent.
Use when spraying hilly land.
3 The boom follows the movements of the trailer to a high extent.
Use when spraying very hilly land.
