For small bits, open jaws enough to insert the
bit up to the flutes. For large bits, insert the bit
as far as it will go. Center the bit as you close
the jaws by hand. This positions the bit
properly, giving maximum contact between the

huck jaws and the bit shank (Fig. 6).
To tighten chuck, insert key into each of the
three key holes in succession and tighten
clockwise firmly.
The chuck can be released by using one hole only.
Note: The 3-Jaw Chuck is for use only in “Drill

ARIABLE SPEED CONTROLLED
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.

to function. Subsequent loss of on/off control
of the trigger switch is likely.
Your tool is equipped with a forward/
reversing lever and trigger lock located above
the trigger (Fig. 9). This lever was designed for
changing rotation of the chuck, and for locking
the trigger in an “OFF” position to help prevent
accidental starts and accidental battery
discharge.

By pressing the button ON, the charged
condition can be checked when the battery is

After approx. 5 seconds, the charged indicator
switches off automatically.
• • • When all three lights are illuminated, this
indicates the battery pack is between 67% and
100% charged.
• • When only two lights illuminate, this
indicates the battery pack is between 33% and
66% charged.
INSERTING AND RELEASING BATTERY PACK
Set Forward/Reversing lever to the center (off
position). Slide charged battery pack into the
housing until the battery pack locks into
position and the red warning label is no longer
visible (Fig. 1).
Your battery pack is equipped with a
secondary locking latch to prevent the battery
pack from completely falling out of the handle,
should it become loose due to vibration.
To remove the battery pack, press the battery

TEMPERATURE INDICATOR LIGHT
The red indicator light signals whether the

optimum temperature range. When the
temperature is too high, the tool will not operate
at full capacity.
If the red indicator light illuminates continuously

The battery is outside the charging temperature

If the red indicator light blinks when the button
or on/off switch (with battery inserted) is

FIG. 11
CHARGER INDICATORS, SYMBOLS AND MEANING
If the indicator lights are “OFF”, the charger is
not receiving power from power supply outlet.
If the green indicator light is
“ON”, the charger is plugged in
but the battery pack is not
inserted, or the battery pack is fully charged.
If the green indicator light is
“BLINKING”, the battery pack is
being fast-charged. Fastcharging will automatically stop when the
battery pack is fully charged.
-12-
BM 1619929800 01-08 1/8/08 9:39 AM Page 13
If the red indicator light is “ON”,
the battery pack is too hot or cold
for fast-charging. The charger
will automatically switch to fast-charging once
a suitable temperature is reached.
CHARGING BATTERY PACK (BC830 1 HOUR CHARGER)
Plug charger cord into your standard power
outlet, then insert battery pack into charger
(Fig. 12).
The charger’s green indicator light will begin to
“BLINK”. This indicates that the battery is
receiving a fast charge. Fast-charging will
automatically stop when the battery pack is
fully charged.
When the unit beeps and the indicator light
stops “BLINKING” (and becomes a steady
green light) fast charging is complete.
The battery pack may be used even though
the light may still be blinking. The light may
require more time to stop blinking depending
on temperature. When you begin the charging
process of the battery pack, a steady red light
If the red indicator light is
“BLINKING”, the battery pack
cannot accept a charge or the
contacts of the charger or battery pack are
contaminated. Clean the contacts of the
charger or battery pack only as directed in
these operating instructions or those supplied
with your tool or battery pack.
could also mean the battery pack is too hot or
too cold.
The purpose of the green light is to indicate
that the battery pack is fast-charging. It does
not indicate the exact point of full charge. The
light will stop blinking in less time if the battery
pack was not completely discharged.
When needed, the internal fan of the charger
will turn on to aid the charging process and
speed.
When charging several batteries in sequence,
the charge time may slightly increase.
When the battery pack is fully charged, unplug
the charger (unless you're charging another
battery pack) and slip the battery pack back
into the tool.

happen if the battery pack is hot from heavy
use). When the battery temperature returns to
between 32˚F (0˚C) and 113˚F (45˚C), the
charger will automatically begin charging.
2. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be
replaced.
3. Remember to unplug charger during storage
period.
4. If battery does not charge properly:
a. Check for voltage at outlet by plugging in
some other electrical device.
b
light switch which turns power “off” when lights
are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d. If you still do not get proper charging,
take or send tool, battery pack and charger to
your local Bosch Service Center. See “Tools,
Electric” in the Yellow Pages for names and
addresses.
Note: Use of chargers or battery packs not
sold by Bosch will void the warranty.

on the tool and the chance of injury to the
operator.
NOTE: The high efficiency available from the
rotary hammers can only be obtained if sharp
and undamaged accessories are used. The
“cost” to maintain sharp and undamaged
accessories is more than offset by the “time
saved” in operating the tool with sharp
accessories.
You will extend the life of your bits and do
neater work if you always put the bit in contact
with the workpiece BEFORE pulling the trigger.
During operation, hold the drill firmly and exert
moderate, steady pressure. Too much
pressure at low speed will stall the hammer.
Too little pressure will keep the bit from cutting
and cause excess friction by sliding over the
surface. This can be damaging to the drill and
bit.
Shanks of all drill bits should be wiped clean
prior to using and immediately after removing.
Recall these instructions for safe operation:
1. Some materials require slow drilling
speeds; whereas, others require higher speed
to produce the best results.
2. All work must be supported or secured
before drilling and steady, even pressure
applied in line with the drill bit.
3. As the drill bit cuts through the opposite
side, reduce the pressure and continue
running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics,
tiles, plastics, etc., should be drilled at low
speeds with specially designed drill bits and
lubricants.
DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the
pressure just before the bit breaks through the
wood to avoid splintering. Complete the hole
from the opposite side immediately after the
point breaks through. If bit binds, reverse the
drilling operation to help remove the bit from
the work.
DRILLING METAL
Make a center punch in the material for easier
starting. Use enough pressure to keep the bit
cutting. If the bit is allowed to merely spin in the
hole, it will become dull within a short time.
When drilling a larger hole, it is faster and
easier on your power pack to first make a
smaller hole and enlarge it to the required size.
Lubricate the tip of the bit occasionally with
CUTTING OIL for easier metal drilling. If bit
binds, reverse the drilling to help remove the
bit from the work.
DRILLING MASONRY
Use carbide-tipped masonry bit for cinder
block, mortar, common brick, soft stone and
other materials. The amount of pressure to
be used is dependent upon the type of
material being drilled. Soft materials require
less pressure while the hard materials need
more pressure to prevent the drill bit from
spinning.
