How to use

Fit a compatible 125 mm hook-and-loop sanding sheet to the pad and select an appropriate speed for the material. Hold the sander with a firm but relaxed grip using the ergonomic palm rest and move it evenly across the surface. For best results, work with gentle pressure and overlapping passes to avoid marks. Empty the dust bag regularly or connect to the Click & Clean dust extraction system for continuous operation. Monitor the battery status indicator and recharge or replace the battery as needed.

Recommendations

Use progressively finer grits for finishing and test speed settings on a scrap piece to find the optimal combination of sanding speed and abrasive for the material. Wear appropriate dust protection when sanding mineral or lacquered surfaces.
