Clean mounting bracket, and remove any burrs that would affect scale installation.
Using a dial indicator check the parallel runout of the scale mounting bracket. For VF-3 only see the next paragraph for indicating runout.
To indicate the full length of the scale mount; jog table all the way to the left and place the magnetic base on the right side of the table as shown.
Zero the indicator, mark the position of the indicator stylus on the scale mount and obtain reading, full travel to the right. Remove magnetic base and place it on the left side of the table. Zero the indicator at the mark on the scale mount and obtain reading, full travel to the left. (T.I.R. .004).
Align if necessary. Verify bolts are tight. If alignment cannot be made within tolerance, shim stock may be used near mounting bolt locations when mounting the scale.
Indicating full length of the scale mount for VF-3 machines cannot be done as described above. Instead, place the magnetic base on the right side of the table and place the indicator as close as possible to the read head. Indicate as much scale mounting surface as possible.
