4.10.1.2 Folding the sprayer booms in or out
Warning!
x When folding in and out the sprayer booms, implicitly ob-
serve the hints in the preface for chapter "Sprayer boom"
on page 95.
x Never put the double acting control valve on the tractor that
actuates the boom folding into the ’’float position’.
Hint!
x The hydraulic rams used for the boom folding keep the
boom in its corresponding final position (either in transport
or working position).
Folding out the sprayer boom
The folded boom package is in the locked transport position
1. Open the block tap for the hydraulic height adjustment.
2. Unlock the transport securing device. Please refer to chapter
"Unlocking the transport securing", page 98.
3. Hold the control lever of the dual acting control valve in position
"folding out" until
• the individual segments have been folded out entirely and
• the swing compensation has been unlocked.
Hint!
x During the unfolding procedure, the right hand boom folds
out first and then the left hand one.
x The swing compensation is unlocked when the green sec-
tion on the unlock/lock tube can be seen.
x The corresponding hydraulic rams lock the boom in opera-
tion position.
4. Setting the sprayer boom height can then be done via the height
adjustment ram.
5. Shut off the block valve for the hydraulic height adjustment.
→ Now the height adjustment is locked and the set sprayer boom
height can be accurately maintained.
