6.2.4.1. Reassembly Notes
1. Adjustment of Grounding Plate Unit
A. After installing, make sure that the Grounding Plate Unit, on the top side of
mechanism chassis, is positioned on the front side of the Cylinder shaft so
that the center line of the plate is just less than 1.0 mm measured from the
center of the Cylinder shaft.
If required, adjust the plate position by loosening Screw (S-1).
Never install the Grounding Plate Unit on the rear side of the Cylinder shaft.
Incorrect positioning will cause cylinder buzz.
