Maintenance
Service
NO USER SERVICE-ABLE
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 heavy
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.
LockJaw™ BLADE HOLDER MAINTENANCE
Use dry compressed air to clean dust and
debris from the LockJaw™ blade holder
assembly on a regular basis.
Periodically lubricate LockJaw™ blade
holder with a dry lubricant such as graphite.
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.

CAUTION
Accessories
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.
