WIRE BRUSHES
Work with brushes requires high speeds.
BRUSHING PRESSURE
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
CORRECT: Wire tips doing the work.
15°
INCORRECT: Excessive pressure can cause wire breakage.

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

2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened brush
life.
RUNNING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
Maintenance

charge battery packs before using after

brushes.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for use. It is recommended that
wires
and
tools with gears be regreased with a special
gear lubricant yearly.
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.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service.
If your tool runs sporadically, loses power,
makes unusual noises or runs at a reduced
speed, check the brushes. To continue using
the tool in this condition will permanently
damage your tool.
