Service

NO USER SERVICEABLE

PARTS INSIDE. Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recom- mend 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.

Cleaning

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.

Certain cleaning agents ! CAUTION and solvents damage

plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Extension Cords

If an extension cord is necessary, a cord with adequate size conductors that is capable of

carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3-wire extension cords that have 3-prong plugs and receptacles.

NOTE: The smaller the gauge number, the heavi - er the cord.
