4. Operating Instructions
4.1 Powering On/Off
To turn the tool ON, depress the trigger switch. To turn the tool OFF, release the trigger switch.
4.2 Speed Selection
The tool features a 2-speed switch located on the top of the tool. Select the appropriate speed setting for your task:
- Low Speed (0-2,800 RPM): Ideal for polishing applications.
- High Speed (0-7,800 RPM): Recommended for sanding applications.
4.3 Polishing Techniques
For best results when polishing, ensure the surface is clean and free of debris. Apply a small amount of polishing compound directly to the pad or the work surface. Start the tool on low speed and move it in a consistent, overlapping pattern. Avoid applying excessive pressure, allowing the tool and compound to do the work.

4.4 Sanding Techniques
When sanding, select the high-speed setting. Use appropriate grit sanding discs for your task, starting with a coarser grit for material removal and progressing to finer grits for a smoother finish. Apply light, even pressure and move the tool in a controlled manner across the surface. Avoid dwelling in one spot to prevent gouging or uneven sanding.

5.1 Cleaning
Regularly clean the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep the ventilation openings clear of dust and debris to prevent overheating.
