8 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.
