To remove the disc table, remove the handles then tilt the disc table upward while pulling it away from the disc. 3. Peel off the old abrasive disc. 4. Thoroughly clean the aluminum disc surface using naptha or a similar non-flammable solvent that will dry film-free. 5. Pull the protective backing half-way off the new abrasive disc. 6. Carefully position the new abrasive disc so it is centered accurately on the aluminum disc. 7. When accurately centered, remove the rest of the protective backing and press the abrasive disc firmly against the aluminum disc so complete adhesive contact is made. 8. Re-install dust cover and table. 9. Reconnect sander to power source.
