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 TRANSPORT POSITION.
IMPORTANT:
Component failure due to oil
contamination is not covered under the
UC4+ Spray Height Control system
warranty. It is recommended that a
qualified technician does the hydraulic
installation.
