6.Depending on the type of metal, you may need to regularly dip the workpiece into the water cup to cool it off. For heat-intensive work, direct a stream of water onto the workpiece and grinding wheel with the flexible water pipe. The flow of water can be increased or decreased using the red valve just below the water cup. If the water supply is exhausted, stop grinding and refill the water cup.

Wheel Care

A large part of your safety while grinding depends on the condition of the grinding wheel. A wheel in poor condition may break apart during rotation, causing serious injury.

To properly care for your wheel, follow these tips:

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

•Select the right grinding wheel for both the job and the machine. DO NOT grind material that is not designed for the wheel. A machine that rotates at a higher RPM than the wheel is rated for may cause the wheel to fly apart.

•Mount the wheels properly. (See the "Replacing Wheels" instructions on Page 19 for guidance.) Never use a wheel with the wrong arbor size for the grinder.

•DO NOT abuse the wheel by jamming the workpiece into the grinding wheel with exces- sive force. This can cause irreparable dam- age to the wheel.

•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.

•Dress the grinding wheel when the surface loses its abrasive quality or becomes unbal- anced.

Wheel Dressing

Dressing restores the grinding wheel with a like- new abrasive quality. Whenever the front surface of the wheel loses its abrasive qualities or balance due to particle loading or polishing of the wheel surface, then the wheel should be dressed. Use a commercially-available dressing tool, such as those available on Page 21.

To dress the grinding wheel:

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

2.Allow the machine to run for at least one full minute to make sure that the grinding wheel is safe to use, 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.

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

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 bal- ance.
