Operating Instructions
Follow these steps for effective and safe polishing:
- Prepare Surface: Ensure the surface to be polished is clean, dry, and free of contaminants.
- Apply Compound: Apply a small amount of polishing compound directly onto the polishing disc or the surface area to be worked on.
- Set Speed: Use the speed dial (typically located on the top or side of the tool) to select the desired speed. Start with a lower speed to spread the compound, then increase as needed. The polisher offers speeds up to 4800 RPM.
- Soft Start Feature: The integrated soft start ensures the machine begins slowly, preventing polishing compounds from splattering and reducing waste.
- Begin Polishing: Place the polishing disc flat on the surface before turning the tool on. Turn on the polisher and move it in a controlled, overlapping pattern. Maintain light, even pressure.
- Constant Speed Electronics: The constant speed electronics maintain consistent power during demanding tasks, ensuring uniform results.
- 21mm Orbit: The 21mm orbit minimizes heat buildup, reducing the risk of burning the lacquer, even during extended use.
- Monitor Results: Continuously check the surface for desired results. Wipe off excess compound with a clean microfiber cloth.
- Finish: Once polishing is complete, turn off the polisher, lift it from the surface, and unplug it from the power source.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your polisher.
- Cleaning: After each use, wipe down the polisher with a clean, dry cloth to remove any dust or compound residue. Do not use harsh chemicals or immerse the tool in water.
- Pad Care: Clean polishing pads thoroughly after each use. Depending on the pad type, they can often be washed with mild soap and water, then air-dried.
- Cord Inspection: Regularly inspect the 4-meter power cord for any signs of damage, cuts, or fraying. If damaged, have it replaced by a qualified technician.
- Storage: Store the polisher in a dry, secure place, out of reach of children. Protect it from direct sunlight and extreme temperatures.
