Check that there is no dust, etc. on the mounting surface, and mount the scale parallel to the machine guide,
as shown in the figure. (Fastening torque : 0.8 N.m = 8 kgf.cm)
The reference surface is shown by the dotted and dashed line in the figure. Adjust the parallelism with the
dial gauge or prepare an abutment on the mounting surface.

Check that there is no dust, etc. on the mounting surface, and mount the reference plate parallel to the
machine guide, as shown in the figure. (Fastening torque: 1.4 N.m = 14 kgf.cm)
The reference hole is located on the left, as shown in the figure. Adjust at the right side while observing
the parallelism with the lever type dial gauge.

The scale is pressed against the reference plate for parallelism when mounting. The reference plate is vital to accurate
scale mounting. Be sure to mount it exactly as described in the specifications.
