maintenance performed by unauthorized personnel may result in misplacing of
internal wires and components which
could cause serious hazard. We recom-
mend that all tool service be performed by a
Bosch Factory Service Center or Authorized
Bosch Service Station. SERVICEMEN:
Disconnect tool and/or charger from power
source before servicing.
BATTERIES
Be alert for battery packs that are nearing
their end of life. If you notice decreased
tool performance or significantly shorter
running time between charges then it is time
to replace the battery pack. Failure to do so
can cause the tool to operate improperly or
damage the charger.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for use.
CARBON BRUSHES
The brushes and commutator in your tool have
been engineered for many hours of
dependable service.
If your tool runs sporadically, loses power,
makes unusual noises or runs at a reduced
speed, check the brushes. To continue using
the tool in this condition will permanently
damage your tool.
Check both brushes. Usually the brushes will
not wear out simultaneously. If one brush is
worn out, replace both brushes.
To check brushes: Disconnect battery pack
from tool. Rotate brush cap at the rear part of
housing counter-clockwise with a coin or
screwdriver and remove cap (Fig. 10).

tool to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
Maintenance
BRUSH
Lift out the brushes; note which way they face,
so that the brushes can be returned to their
original position. New brushes can also be
inserted turned 180º. Clean the brush holder
openings with compressed air or a clean cloth
and replace the brushes and brush covers.
After replacing brushes the tool should be run
at no-load and run it freely at full speed for 2
minutes before using the tool. This will allow
the brushes to "seat" properly and will give
you more hours of life from each set of
brushes.
Only genuine Bosch replacement brushes
specially designed for your tool should be
used.
The motor in your tool has been engineered
for many hours of dependable service. To
maintain peak efficiency of the motor, we
recommend it be examined every six months.
Only a genuine Bosch replacement motor
specially designed for your tool should be
used.
