NSTALLATION
If your sprayer has a valve block
with serial number 21.12732 or lower

complete the hydraulic plumbing.
WARNING!
The hydraulic system creates very
high pressure. Before disconnecting
any hydraulic lines ensure all pressure
has been bled from the system.
When changing the boom hydraulic
hoses leave the booms in
