b. Tap the flat side of the wheel with a light non-metallic object, such as a screwdriver handle, at a point 45° from the vertical center line on each side of the wheel and 1 – 2 inches from the edge of the wheel (see Il- lustration).

c. Rotate the wheel 45 degrees and repeat the test until the entire wheel has been checked.

d. An undamaged wheel will give a clear tone. If cracked, there will be a dead sound and not a clear ring.

5.Slip the grinding wheel onto the Spin- dle with a paper gasket, or blotter, first. The blotter should be centered on the grinding wheel and the wheel and blotter should rest flat against the

Inner Flange.

WARNING: To prevent serious injury, blotters must be used for all grinding wheels they are provided

with. Blotters help prevent grind- ing wheel damage and wheel slip- page, causes of wheel failure.

6.Thread the Outer Flange Arbor Nut onto the Spindle. Wrench tighten

only enough so that the wheel is se- curely held on the spindle.

WARNING: To prevent serious injury, do not overtighten flange. Overtightening can damage the wheel, causing wheel failure.
