PARTS INSIDE. Preventive
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.
D.C. MOTORS
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.

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. Remove brush cover at the rear part
of housing by loosening screws (Fig. 12).

red notch of the carbon brush and lift out the

After replacing brushes the tool should be run
at no-load and run it freely at full speed for 2
