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. Battery packs typically last
from 500 to 1000 charges. 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.

plugs and receptacles.
