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 Autho rized Bosch
Service Station.
SERVICE REMINDER LIGHT
When the service reminder light lights up or
blinks, this will indicate that the cut-out carbon
brushes will switch off the tool in approximately 8
hours. After that period, the light will go off and
the tool will stop running. The tool must then be
sent to a service center for service (Fig. 6).

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

been engineered for many hours of dependable
service. To maintain peak efficiency of the
motor, we recommend every two to six months
