Check for damage visually.
Use “COLOR CHECK” if necessary to check
for cracks and other damage. Repair damage if
possible or replace.

Check the top surface for distortion with a
straight rule and thickness gauges in diagonal
ways as shown in the figure.

If distortion exceeds the usable limit, correct on

rected within the ground-down limit should be
replaced with a new one.
