How to use

Before operation, select the appropriate abrasive or polishing pad for the material and desired finish. Ensure the work area is clean, free of loose debris and properly ventilated. Hold the tool with both hands and guide it steadily across the surface at a controlled pace to maintain even contact; avoid applying excessive pressure which can cause uneven results. Change pads as they wear and inspect the surface periodically until the required level of finish is achieved. Follow all safety instructions in the manufacturer's manual, including the use of eye, hearing and respiratory protection as needed.

Recommendations

For best results, start with a coarser abrasive to remove old coatings or level the surface, then progress to progressively finer grits for smoothing and polishing. Test on a small inconspicuous area before treating the entire surface. Store the tool in a dry place and perform regular maintenance checks to ensure consistent performance.
