  We carry out an advanced morpho-kinematic analysis of the Planetary Nebula
(PN) NGC 2818, whose complex morphology is described by a basic bipolar
component, filamentary structures and a knotty central region. We performed an
upgrated 3D Morpho-kinematic (MK) model by employing the SHAPE software,
combining for the first time in PNe optical 2D spatially resolved echelle
spectra and Fabry-Perot data cubes. The best-fitting 3D model of NGC 2818
successfully reconstructs the main morphology, considering one bipolar
component, radial filamentary structures, and an equatorial component as the
geometrical locus of the group of cometary knots. The model shows that the
equatorial component has the lower expansion velocity of the system at 70 $\pm$
20 km/s. The velocity of the bipolar component is 120 $\pm$ 20 km/s, while all
the filamentary structures were found to expand at higher velocities of 180
$\pm$ 20 km/s. Moreover, Fabry-Perot data revealed for the first time a
north-eastern filament expanding at a mean velocity of 80 $\pm$ 20 km/s, while
its equivalent counterpart in the southwestern region was confirmed by a new
detected substructure in the echelle data. A new detected knotty structure at
velocity -40 $\pm$ 20 km/s is also reported, as expelled material from the
fragmented eastern lobe of the nebula. We interpret the overall structure of
NGC 2818 as the result of the evolution of a binary system that underwent the
common envelope phase, in conjunction with the ejections of a magnetized jet,
misaligned with respect to the symmetry axis of the bipolar/elliptical shell.
