HYDRAULIC INSTALLATION
WARNING!
The hydraulic system creates very high
pressure. Before disconnecting any
hydraulic lines ensure all pressure has
been bled from the system.

qualified technician does the hydraulic
installation.
Sprayers with a model year of
2007 and older require the main lift valve
to be changed. See Section 4 for
instructions on how to do this.
