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.
CHUCK LUBRICATION
The wrenchless chuck has been properly
lubricated and is ready to use. If the chuck's
jaws begin to stick during use, the chuck

the sides of the jaws, and adjust the chuck
through its full range of motion to distribute
the grease.
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
two to six months the brushes be examined.
