Using the NB10 Compact 3 - Head Planetary Polisher is easy. First, make sure the power supply matches the 110V/220V requirement. Then, attach the appropriate heads with 5/8 - 11 thread according to your task, like re - polishing, honing, or leathering. Adjust the oscillation speed based on the material and the finish you want. For best results, start at a lower speed and gradually increase it. When using it, keep the polisher moving evenly over the surface to avoid uneven polishing. After use, unplug the polisher and clean the heads. Store it in a dry place to prevent damage. If you notice any issues, stop using it immediately and check for problems. Regularly inspect the power cord and other parts for wear and tear.
