The tool is operated in much the same way as when sanding, but the following points should be observed; Apply the compound to the surface, and use the sponge applicator pad with light pressure and a circular motion to remove scratches and restore weathered finishes. Use only as much compound as necessary, and clean the sponge frequently during use. When initial polishing is completed, wipe away any excess compound with a soft towel, and then polish the surface to its final finish with the polishing bonnet. Use smooth overlapping strokes for best results. It is important to note that the orbit speed of the random orbit sander is not the same as the RPM of a standard right-angle polisher. The random orbit action is much like a powerful hand polishing action, and therefore does not have the high speeds at the edge of the pad which can burn the work surface. For this reason, it is possible to select a higher OPM for the random orbit sander than the recommended RPM for a standard polisher. Practice on a hidden area or test surface until you have determined the tool is suitable for your polishing application. Clean the buffing pad and polishing bonnet with mild detergents and warm water. DO NOT use solvents. Maintenance Service ! WARNING Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station. TOOL LUBRICATION Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change. CARBON BRUSHES The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used. BEARINGS After about 300-400 hours of operation, or at every second brush change, the bearings should be replaced at Bosch Factory Service Center or Authorized Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure. Cleaning ! WARNING To avoid accidents always disconnect the tool from the power supply before cleaning or performing any maintenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air. Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings. ! CAUTION Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia. -9-
