10 Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines
or fittings. Hydraulic pressure will exist on the wing tilt circuits unless the wings
are being supported by other means. The hydraulic installation may be performed
with the wings in transport position, resting on the ground or with the tilt cylinders
fully extended.
Component failure due to oil contamination is not covered under the NORAC UC5
system warranty. It is recommended that a qualified technician perform the
hydraulic installation.
Before assembling the valve block, identify if the sprayer tilt cylinders are single
acting or double acting. A single acting cylinder will only have one hose running to
it, while a double acting cylinder has two hoses routed to it.
