Wheel Care

Wheel Dressing

Your safety depends, on a large part, on the condition of the wheel during grinding. A wheel in poor condition presents the possibility of breaking apart during rotation, injuring the operator and possibly causing property damage.

To properly care for your wheel, follow these tips:

Always transport, store and handle wheels with care. Wheels may be damaged if they are dropped or if heavy objects are stacked on them.

Select the right grinding wheel for the job. DO NOT grind material that is not designed for the wheel.

Select the right wheel for the machine. A machine that rotates at a higher RPM than the wheel rating may cause the wheel to fly apart.

Mount the wheels properly. (See the “Replacing Wheels” instructions on Page 18 for guidance.) Never use a wheel with the wrong arbor size for the grinder.

DO NOT abuse the wheel by jamming the work into the grinding wheel with excessive force.

Learn how to use the grinder and the grinding wheels properly. Ask a trusted person with experience or consult with your local library to learn more.

Grinding on the side of the wheel may cause wheel damage.

Dress the grinding wheel when the surface loses its abrasive quality or “bite.”

Dressing restores the grinding wheel with a like- new abrasive quality. Whenever the front surface of the wheel loses its abrasive qualities (loading or polishing), then the wheel should be dressed. A dressing tool is included for this purpose.

To dress the grinding wheel:

1.With the machine plugged into power, stand to the side of the grinding wheel and move the red switch to the ON position.

2.Allow the machine to run for at least 1 full minute to make sure that the grinding wheel is not going to fly apart and injure you, then move to the front of the machine.

3.Hold the dressing tool firmly on the tool rest with both hands and press it lightly against the front surface of the grinding wheel as shown in Figure 10.

Figure 10. Using wheel dressing tool.

4.Move the dressing tool in a side-to-side motion, while keeping it even with the front surface of the grinder.

5.Regularly pull the dressing tool away from the wheel for visual inspection and repeat Steps 3 & 4 until the surface of the wheel appears to be restored to its normal color and tex- ture.
