Using the Milwaukee M18 FUEL 21mm Random Orbital Polisher is a breeze. First, make sure the battery is fully charged and properly inserted into the polisher. Then, select the appropriate speed on the 8 - position speed dial according to the task at hand, whether it's light polishing or heavy defect correction. Press the variable speed trigger to start the polisher. You can lock the trigger on for continuous use to reduce fatigue. When using, keep the polisher flat on the surface and move it in a smooth, circular motion. Be careful not to apply too much pressure as it might damage the surface. For maintenance, after each use, clean the polisher with a dry cloth to remove any dust or debris. Store the batteries in a cool, dry place. Periodically check the charger and batteries for any signs of damage. Always use only Milwaukee - recommended chargers and batteries to ensure safety and optimal performance.
