How to Use an M12 Polisher/Sander Effectively

Using the M12 Polisher/Sander correctly ensures the best results and extends the tool’s lifespan.

Step 1: Choose the Right Pad

Select an appropriate sanding or polishing pad based on your project. Use finer grit sanding pads for finishing and softer polishing pads for shine.

Step 2: Attach the Pad Securely

Ensure the pad is properly attached to the tool’s backing plate to avoid slipping or uneven polishing.

Step 3: Adjust Speed

Start with a lower speed to avoid damaging the surface and increase gradually based on need.

Step 4: Work in Small Sections

Polish or sand small sections at a time, moving the tool steadily and evenly to prevent swirl marks or gouges.

Step 5: Apply Consistent Pressure

Apply moderate, even pressure — too much pressure can damage the surface or tool, while too little might not be effective.

Step 6: Clean and Maintain

After use, clean the pads and tool, inspect for wear, and charge batteries to keep the tool ready for the next task.
