 When a measuring tape is used, check to be su re there is no elongation, twisting or bending.
 Measurements should be taken at the center of the mounting holes.
 An asterisk (*) following the value at the measuring poi nt indicates that the measuring point on the other side
is symmetrically the same value.
 The coordinates of the measurement points are the distances measured from the standard line of ″X ″, ″Y ″
and ″Z ″.
 ″Z ″: Imaginary base line [300 mm (11.81 in) below datum line ( ″0Z ″ at design plan)]
