Operating Instructions
Follow these steps for effective and safe operation of your polisher/sander.
- Power On: With the appropriate pad/bonnet attached, hold the tool firmly with both hands using the main grip and the D-handle. Press the power switch to turn the tool on.
- Adjust Speed: The tool features variable speed control, allowing for 0-4200 no-load RPM. Use the speed adjustment dial (typically a thumb wheel) to select the desired RPM for your specific task. Lower speeds are generally used for polishing and waxing, while higher speeds are suitable for sanding.
- Application:
- Polishing/Waxing: Apply a small amount of polish or wax directly to the foam applicator or the surface. Start the tool at a low speed and spread the product evenly before increasing speed as needed. Move the tool in a consistent, overlapping pattern.
- Sanding: Ensure the sanding disc is securely attached. Start the tool before making contact with the surface. Apply light, even pressure and move the tool smoothly across the surface to avoid gouging.
- Safety Lockout: The tool is equipped with a comfortable paddle switch with a safety lockout feature. Familiarize yourself with its operation to prevent accidental starts.
- Power Off: When finished, release the power switch. Wait for the pad to come to a complete stop before setting the tool down. Disconnect the tool from the power source.
