CAUTION: Secure work to prevent it from moving during the sanding operation. Friction between the sanding disc and work will try to spin work away from sander and may cause bodily injury. 2. CAUTION: Wear safety glasses and dust mask. 3. Hold sander firmly by the rear and auxiliary handles, making sure sanding disc is clear of work and foreign objects. Start sander and lower at an angle so that approximately 1" to 11/4" of the sanding disc contacts the work (see Fig. 7). Too great an angle may result in gouging or snagging the work, while too small an angle results in extreme difficulties in controlling the sander. Fig. 7 4. Move sander in long sweeping overlapping strokes as you go back and forth. Do not move sander in a circular motion or stay in one spot too long as this will produce swirls and an uneven finish. The weight of the sander applies sufficient pressure for fast stock removal. Additional pressure will only slow the sander down and decrease removal of stock. 5. Lift sander from work before turning off motor. 6. Always be sure motor has stopped before setting sander down. 7. For rough sanding and quick stock removal, use a coarse grit sanding disc. For a fine finish, use a medium grit disc, followed by a fine grit disc. Do not go directly from a coarse grit to a fine grit, as it is difficult to remove marks left by the coarse grit disc. THE POLISHER TO INSTALL POLISHING PAD The Porter-Cable Polisher has a “Hook and Loop” style back-up pad and buffing pad. A “Hook and Loop” compounding pad is available as an accessory (see list in back of this manual). No wrenches are required for installation or removal. 1. CAUTION: DISCONNECT TOOL FROM POWER SOURCE. 2. Depress spindle lock pin (see Fig. 8) and rotate back-up pad clockwise onto spindle until it seats. 3. Align the buffing pad (or the accessory compounding pad) with the backup pad and press in place firmly. 9 892459 - 11-30-00.QXD 2/25/02 8:23 AM Page 10 A B C D Fig. 8 A Spindle Lock Pin B Spindle C Back-up Pad D Buffing Pad 4. TO REMOVE: DISCONNECT TOOL FROM POWER SOURCE, grasp edge of the buffing pad (or compounding pad) and “peel” away from backup pad, engage spindle lock pin and rotate back-up pad counterclockwise to remove. USING POLISHER 1. If item to be polished is light enough to be moved by the rotating polishing pad, it should be securely anchored to prevent possible bodily injury. 2. Hold polisher firmly by the rear and auxiliary handles, making sure polishing pad is clear of work and foreign objects. Start polisher and lower at an angle so that approximately 1/2 or slightly less of the polishing pad contacts the work. 3. Move polisher in long continuous sweeping strokes. DO NOT HOLD POLISHER IN ONE SPOT as this will create heat and possibly damage surface being polished. 4. Lift polisher from work before turning off motor. 5. Always be sure motor has stopped before setting polisher down. POLISHING TIPS USE ONLY QUALITY POLISH MADE FOR POWER POLISHING APPLICATION and apply per manufacturer’s instructions. For best results, thoroughly clean surface to be polished. When polishing automobiles, wash the car thoroughly to remove dust, dirt and other abrasives that may scratch the finish. Buffs or pads may become gummed up after a period of use. They may be washed out with soap and water. Shake out as much water as possible and then spin dry on machine. Do this in an area where you will not splatter articles. 10 892459 - 11-30-00.QXD 2/25/02 8:23 AM Page 11 MAINTENANCE KEEP TOOL CLEAN Periodically blow out all air passages with compressed air. Remove buildup of grime resulting from working with green or sappy woods. All plastic parts should be cleaned with soft cloths. NOTE: Never use solvents to clean plastic parts. Plastics can be easily damaged by such solvents. CAUTION: Wear safety glasses while using compressed air. FAILURE TO START Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line. BRUSH INSPECTION AND LUBRICATION At approximately 100 hours of use, take or send your tool to your nearest Authorized Porter-Cable Service Station to be thoroughly cleaned and inspected; worn parts replaced, when necessa...
