ENGLISH
5 BAR CONNECTION TO THE CENTRAL ENGINES
Connect each end piece to the corresponding connec-
tor of bracket A on the central engines by means of a
screw, a washer and a self-locking M6 nut (supplied
in bag F) using the 10 mm and 16 mm wrenches with
a tightening torque of 8.5 Nm (6.27 lb ft).
6 Once operation 5 has been completed, in order to avoid accidental changes to the bars, they must be
locked by tightening ring nut (18) using a 22 mm wrench with a tightening torque of 40 [Nm] (29.52 [lb ∙ ft]) by
means of a second wrench on the end element (19).
WARNING
DO NOT FORCE THE UNSCREWING OF THE BAR'S END WHEN REACHING THE MAXIMUM EXTENSION.
DANGER
FORCING THE UNSCREWING OF THE BAR'S END WILL IRRETRIEVABLY DAMAGE THE BAR.
NOTE
Be careful not to damage the exposed thread: dents on the thread cause seizure of the parts.
NOTE
The correlation of the distance between centers is L2 or L3 and the bar length depends on the chosen diver-
gence or convergence angle.
