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. You may wish to perform the hydraulic
installation 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.
