How to use

Choose a compatible 12 V Bosch Professional battery and attach it to the tool. Select the appropriate sanding paper and secure it to the 125 mm hook-and-loop pad. Switch the sander on and select the speed suited to the material: lower speeds for delicate finishes and higher speeds for aggressive material removal. Guide the sander with light, even pressure, keeping it flat on the workpiece and moving it continuously to avoid creating dips or heat build-up. Empty the dust bag regularly or connect the Click & Clean dust extraction system for improved dust control.

Recommendations

Use suitable grit progression for the task (coarse to fine) and check compatibility of abrasives with a 125 mm pad. For best results on painted or lacquered surfaces, start with a medium grit and finish with a fine grit. Wear appropriate personal protective equipment, including eye protection and a dust mask, when sanding.
