Operating Metal Abrasive Tools

The following outlines basic operation and etiquette when for shaping and buffing parts on the grinders and wheels.

Step 1: Using the Disc and Belt Sander

1. Turn on the power and wait for the sander to come up to speed.
2. Keep the material flat on the table.
   • If you can’t do this, use a hand-held tool to shape your work.
3. Slowly push the material into the sandpaper.
   • Let the machine do the work for you; excessive force is not required.
   • Do not sand on one spot; move the workpiece back and forth on the table.
4. Stay in control of material - use two hands.
   • Small parts require locking pliers.
5. Turn off the power.

Step 2: Using the Deburring or Wire Wheel

1. Turn on the power and wait for the machine to come up to speed.
2. Only work in the 3:00 to 6:00 position.
3. Slowly push the material into the wheel.
4. Avoid exposing an edge to the wheel.
   • Keep work slightly pointed down.
5. Stay in control of material - use two hands.
   • Small parts require locking pliers.
6. Turn off the power.

Step 3: Using the Polishing Wheel

1. Turn on the power and wait for the machine to come up to speed.
2. Only work in the 3:00 to 6:00 position.
3. Add compound to the wheel, using the block.
4. Slowly push the material into the wheel.
5. Avoid exposing an edge to the wheel.
   • Keep material slightly pointed down.
