Maintenance and Service

WARNING! Preventive maintenance per-

formed by unauthorized personnel may result

in misplacing of internal wires and compo-

nents which could cause serious hazard. We

recommend that all tool service be performed

at a Bosch Factory Service Center.

Tool Lubrication

Your Bosch tool has been properly lubricated

and is ready for use. We recommend, that tools

with gears be regreased with a special gear

lubricant every time the brushes are changed.

Carbon Brushes

The brushes and commutator in your Bosch

tool have been engineered for many hours of

dependable service. To maintain peak effi-

ciency of the motor, we recommend that every

two to six months the brushes be examined.

Only genuine Bosch replacement brushes spe-

cially 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 a Bosch Factory Service Center.

Bearings which become noisy (due to heavy

load or very abrasive material cutting) should

be replaced at once to avoid overheating and

motor failure.

Cleaning

WARNING! To avoid accidents, always dis-

connect the tool from the power supply before

cleaning or performing any maintenance. The

tool may be cleaned most effectively with

compressed 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 sol-

vents damage plastic parts. Some of these are:

gasoline, carbon tetrachloride, chlorinated

cleaning solvents, ammonia and household

detergents that contain ammonia.
