Wheel Inspection

Do not assume that a wheel is in sound condition just because it is new—often damage can occur in shipping, with age, or with exposure to mois- ture. Inspect every wheel for damage.

First, do a Visual Inspection. Look for any cracks, chips, nicks or dents in the surface of the wheel. If you see any of these, DO NOT use the wheel.

Second, do a Ring Test, by following Steps 1-5below. This test will give you an indication of any internal damage that may not be obvious during a visual inspection.

Always be sure to use a wheel that is rated for 3450 RPM or greater.

To perform a Ring Test:

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

2.If size permits, balance the wheel with your finger in the hole. If this is not possible, 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 11, gently tap the wheel with a light non-metallic device such as the handle of a screwdriver or a wooden mallet.

4.An undamaged wheel will emit a clear metal- lic 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!

Wheel Dressing

Depending on the type of grinding you do, the grinding wheel may require periodic dressing.

Several different kinds of wheel dressing devices are available (see Page 19). Dressing restores the abrasive quality of the wheel surface and squares up the wheel edge.

Refer to the instructions that accompany your dressing accessory for complete details on how to properly dress a wheel.

Wheel Replacement

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

To replace a grinding wheel:

1.DISCONNECT THE GRINDER FROM POWER!

2.Remove the three Phillips head screws and nuts that go through the outer guard, and remove the outer guard.

3.Block the wheel from turning, then remove the arbor nut that secures the wheel.

Note: The arbor shaft and nut on the left side of the grinder (as you face front) has left hand threads; to loosen this nut, turn it clockwise.
