TOOL LUBRICATION
Your Bosch tool has been properly lubricated
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
The brushes and commutator in your tool have
been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
