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