6.2 TIGHTENING TORQUES

The tightening torques stated in this section are
different from the standard tightening torques
included in the overview of standard tightening
torques. Any other threaded connections that
are not specified must therefore be tightened to
the tightening torque stated in the overview of
standard tightening torques.

When attachment bolts and nuts are to be
replaced, it is important - unless stated
otherwise - that these bolts and nuts are of
exactly the same length and property class as
the ones removed
