How to use

Ensure the eccentric sander is disconnected from power before fitting a sanding sheet. Align the sanding sheet with the sander pad and press firmly so the hook-and-loop backing attaches evenly. Start sanding with moderate pressure and let the abrasive do the work; excessive force can reduce sheet life and affect finish quality. Replace the sheet when abrasive performance declines or the backing becomes clogged with debris.

Usage recommendations

For best results, use the Bosch Expert C470 K40 sheets on dry, clean workpieces and remove loose debris before sanding. Progress to finer grits after initial stock removal to achieve the desired surface finish. Wear appropriate personal protective equipment such as eye protection, dust mask and hearing protection during sanding operations.
