BM 2610944508 11-06 12/1/06 3:29 PM Page 15 Maintenance Service ! WARNING NO USER SERVICEABLE PARTS INSIDE, except for the replaceable carbon brushes. 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. SERVICEMEN: Disconnect tool and/or charger from power source before servicing. BATTERIES Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger. TOOL LUBRICATION Your Bosch tool has been properly lubricated and is ready for use. D.C. MOTORS The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used. CARBON BRUSHES The brushes and commutator in your tool have been engineered for many hours of dependable service. If your tool runs sporadically, loses power, makes unusual noises or runs at a reduced speed, check the brushes. To continue using the tool in this condition will permanently damage your tool. Check both brushes. Usually the brushes will not wear out simultaneously. If one brush is worn out, replace both brushes. To check brushes: Disconnect battery pack from tool. Remove brush cover at the rear part of housing by loosening screws (Fig. 9). BRUSH COVER BRUSH HOLDER FIG. 9 Insert a screwdriver or similar object into the red notch of the carbon brush and lift out the brushes; note which way they face, so that the brushes can be returned to their original position. Clean the brush holder openings with compressed air or a clean cloth and replace the brushes and brush covers. After replacing brushes the tool should be run at no-load and run it freely at full speed for 2 minutes before using the tool. This will allow the brushes to "seat" properly and will give you more hours of life from each set of brushes. Only genuine Bosch replacement brushes specially designed for your tool should be used. Cleaning ! WARNING To avoid accidents, always disconnect the tool and/or charger from the power supply before cleaning. 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 opening. ! 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. -15-
