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.
