Fasten ring nut (1-4). Install ring nut between angu-
lar bearings and flange holder, and tightly fasten the
ring nut until there is no gap between the angular
bearings and flange holder. Measure the startup
load at the housing mounting screw (M16) after a
couple of times rotation. This startup load is called F
[N]. Fasten ring nut so as to adjust the startup load
to be equal to F + (108 to 127) [N]. Tighten plug (1-

by punching at two diametrically opposed locations
to prevent the plug (1-5) from loosening.
