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 Au horizedt Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cut ing)t should be replaced at once to avoid overheating or motor failure.

Cleaning

performing any main tenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety gog gles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not at tempt to clean by inserting pointed objects through openings.

plastic parts. Some of these are: gasoline, carbon tetrachlo ride, chlo rinated cleaning solvents, ammonia and house oldh 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.
