To perform a Ring Test:

1.Make sure the wheel that you test is clean and dry; otherwise, you may get false results.

2.Hang the wheel in the air with a piece of cord or string looped through the hole in the center.

3.At the spots shown in Figure 7, gently tap the wheel with a light non- metallic device such as the handle of a screwdriver or a wooden mallet.

Figure 7. Ring test tapping locations.

4.An undamaged wheel will emit a clear metallic ring or “ping” sound in each of these spots. A damaged wheel will respond with a dull thud that has no clear tone.

5.If you determine from the ring test that the wheel is damaged, DO NOT use it!

Replacing Wheels

The wheel guard assembly must be removed in order to mount or dismount a buffing or grinding wheel.

To remove/mount a wheel:

1.DISCONNECT THE MACHINE FROM THE POWER SUPPLY!

2.Remove the three Phillips head screws and tooth washers that go through the outer guard, and take off the outer guard.

3.Use a wrench on the nut that holds the wheel on the arbor. Hold the wheel from turning with your other hand.

Note: The left end of the arbor has a left-handed thread, so loosening the nut will require turning it clockwise.

4.Remove the outer wheel flange and paper disc. Pull the wheel free from the arbor. There will also be a paper disc and a wheel flange on the back side of the wheel which should also be removed.

5.Mount the new wheel in the reverse order that you removed it or as shown in Figure 8. Always make certain there are paper or fiber discs between the wheel flanges and the wheel itself. Tighten the nut snugly but DO NOT over-tighten. Over-tightening can crack a grinding wheel.
