The processes for grinding and buffing with the H7757 are very similar.

To grind or buff:

1.Ensure all eye shields are in place and that you are wearing the appropriate safety gear.

2.With the machine plugged into power, stand to the side of the machine, and turn it ON.

3.Allow the machine to run for at least one full minute to ensure that the wheels are safe for use, then move to the front of the machine.

4.Grasp the workpiece tightly and prop- erly support it on the appropriate tool rest.

5.Place the workpiece against the front surface of the wheel with moderate pressure, moving it back and forth in a steady, even motion.

Note: Using too much pressure will slow the motor and may damage the wheel. Using too little pressure will make the workpiece bounce around and you will not make good contact with the wheel.

6.After turning the buffer OFF, DO NOT continue grinding or buffing and DO NOT manually stop either wheel with your workpiece!

Your safety largely depends on the con- dition of the wheels during grinding or buffing. A grinding wheel in poor condition presents the possibility of breaking apart during rotation and injuring the operator, while a buffing wheel in poor condition can tear apart and snag a workpiece, potentially causing serious entanglement injuries.

To properly care for your wheel, follow these tips:

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

•Select the right wheel for the job. DO NOT grind or buff 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 break or tear apart.

•Mount the wheels properly. (See the Replacing Wheels instructions on Page 13 for guidance.) Never use a wheel with the wrong arbor size for the buffer.

•DO NOT abuse a wheel by jamming the workpiece into the wheel with excessive force.

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