WARNING!
The hydraulic system creates very high pressure that can injure. Before
disconnecting any hydraulic lines ensure that all pressure has been bled
from the system. When changing the boom hydraulic hoses leave the
booms in the TRANSPORT POSITION.
IMPORTANT:
Hydraulic component failure due to oil contamination is not covered
under the warranty of your UC4 system. Therefore, it is strongly
recommended that a qualified technician, using proper installation
