Usage and Maintenance
Install the foam backup pad by removing the stock nut on your Porter-Cable sander, slipping the pad over the arbor, and reattaching the nut. Use only hook-and-loop sanding discs designed for 9″ pads. To maximize pad life, clean the foam surface periodically to remove dust buildup and store the sander face-down on a clean surface when not in use.
