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.
Long term battery storage should be in
the discharged state. Battery packs last
longer and re-charge better when they are
stored discharged. Remember to fully re-
charge battery packs before using after
prolonged storage.

and receptacles.
NOTE: The smaller the gauge number, the

the sides of the jaws, and adjust the chuck
through its full range of motion to distribute

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.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating and
motor failure.
