TIGHTENING TORQUE
Locking devices ( e.g.: locking tabs, elastic stop nuts ,self-locking fasteners ,etc.) must be installed or replaced
with new ones, where specified. If the efficiency of a locking device is impaired, it must be renewed.
In order to avoid a poor assembling, tighten screws, bolts or nuts in accordance with the following
recommended torque value:
