2. General Safety Instructions
Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury.

5.2 Speed Control
The DEXTER Polisher is equipped with a speed regulator, allowing you to adjust the rotation speed from 600 to 3300 RPM. This ensures a better finish and allows for precise control depending on the material and desired result. The speed remains constant regardless of the pressure applied.
- Rotate the speed control dial (location typically near the handle or motor housing) to increase or decrease the RPM.
- Start with a lower speed for initial application of polish or wax, and gradually increase as needed for buffing and finishing.
5.3 Polishing Techniques
- Apply a small amount of polishing compound directly to the polishing pad or the surface to be polished.
- Place the polisher flat on the surface before turning it on to prevent splashing.
- Move the polisher in a consistent, overlapping pattern (e.g., cross-hatch or circular motions) to ensure even coverage.
- Maintain light, even pressure. The anti-vibration handle enhances comfort during extended use.
- For optimal results, work on small sections at a time.
