Maintenance
Service
NO USER SERVICEABLE
PARTS INSIDE. Preventive
maintenance performed by un au thorized
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. SERVICE MEN:
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.
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 com pressed 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, car bon
tetrachloride, chlorinated cleaning solvents,
ammonia and household detergents that
contain ammonia.

Accessories
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your

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
