5.2.1 Lubrication of mechanism
For normal duty the HLA actuator is lubricated "for life". In case of

necessary to periodically restore the lubrication: it is advisable to
apply a generous coating of grease on the contact surfaces of
moving parts. For this operation is necessary to disassemble the
closing plates (item 41 refer to table pag.34) from pedestal with
coupling-joint.
The following grease is used by BIFFI for standard working
temperature and suggested for re-lubrication:
