If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used.
This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-
wire extension cords that have 3-prong
plugs and receptacles.
NOTE:
The smaller the gauge number, the
heavier the cord.

WARNING
Accessories
Service
NO USER SERVICEABLE
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.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for use. It is recommended that
tools with gears be regreased with a special
gear lubricant yearly.
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.
Cleaning
To avoid accidents,
always disconnect the
tool and/or charger from the power
supply before cleaning.
The tool may be
cleaned most effectively with compressed
dry air.
Always wear safety goggles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through opening.
Certain cleaning agents
and solvents damage
plastic parts.
Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household
detergents that contain ammonia.
