Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Do not abuse the cord. Never use the
cord to carry the tool. Keep cord away
from heat, oil, sharp edges, or moving
parts. Replace damaged cords
immediately. Damaged cords may create a
fire.
A battery operated tool with integral
batteries or a separate battery pack must
be recharged only with the specified
charger for the battery. A charger that may
be suitable for one type of battery may
create a risk of fire when used with another
battery.
Use battery operated tool only with
specifically designated battery pack. Use
of any other batteries may create a risk of
fire.
Personal Safety
Stay alert, watch what you are doing, and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
Avoid accidental starting. Be sure switch
is in the locked or off position before
inserting battery pack. Carrying tools with
your finger on the switch or inserting the
battery pack into a tool with the switch on
invites accidents.
Remove adjusting keys or wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enable better control of the tool
in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.
Do not use tool if switch does not turn it
on or off. A tool that cannot be controlled
with the switch is dangerous and must be
repaired.
Disconnect battery pack from tool or
place the switch in the locked or off
position before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
When battery pack is not in use, keep it
away from other metal objects like: paper

Cordless Rotary Hammer Safety Rules
clips, coins, keys, nails, screws, or other
small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns, or a fire.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edge are less likely
to bind and are easier to control.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tool's
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools.
Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool may create a risk of injury when
used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel may result in a risk of injury.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of shock or injury.
Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring.
Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the
operator. Do not drill, fasten or break into
existing walls or other blind areas where
electrical wiring may exist. If this situation is
unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.
Before changing accessories remove
battery pack. Accidental starting may
occur because battery tools with a battery
inserted are in the operative condition.
Do not use dull or damaged bits and
accessories. Dull bits or accessories can
frequently bind in the work causing a torque
reaction.
Always wear safety goggles or eye
protection when using this tool. Use a
dust mask or respirator for applications
which generate dust.
Always use the auxiliary handle for
maximum control over torque reaction or
kick-back. Never attempt to operate this
tool with one hand. The slip clutch engages
only if you apply sufficient force to the tool
during a torque reaction or kick-back.
If the bit becomes bound in the workpiece, release the trigger immediately,
reverse the direction of rotation and
slowly squeeze the trigger to back out the
bit. Be ready for a strong reaction torque.
The hammer body will tend to twist in the
opposite direction as the bit is rotating.
Avoid being caught between the rotary
hammer and walls or posts. Should the bit
become bound or jammed into the work, the
reaction torque of the rotary hammer could
crush your hand or leg.
Do not strike the bit with a handheld
hammer or sledge tool when attempting
to dislodge a bound or jammed bit.
Fragments of metal from the bit could
dislodge and strike you or bystanders.
Do not run the tool while carrying it at
your side. The spinning drill bit may become
entangled with clothing and injury may
occur.

Before using battery charger, read all
instructions and cautionary markings on
(1) battery charger, (2) battery pack, and
(3) product using battery.
Use only the charger which accompanied
your Cordless Rotary Hammer or direct
replacement as listed in the catalog or
this manual. Do not substitute any other
charger. Use only Bosch battery charger
Nos. BC015 & BC016 with your Cordless
Rotary Hammer.
Do not disassemble charger or operate
the charger if it has received a sharp
blow, been dropped or otherwise
damaged in any way. Incorrect reassembly
or damage may result in electric shock or
fire.
Do not recharge battery in damp or wet
environment. Do not expose charger to
rain or snow. If battery case is cracked or
otherwise damaged, do not insert into
charger. Battery short or fire may result.
Charge only Bosch Nos. BAT019, BAT020
and BAT021, rechargeable batteries with
the above listed charger. Other types of
batteries may burst causing personal injury
and damage.
Charge battery pack in temperatures
above +32 degrees F (0 degrees C) and
below +113 degrees F (45 degrees C).
Store tool and battery pack in locations
where temperatures do not go below 32
degrees F (0 degrees C) or will not exceed
120 degrees F (49 degrees C). This is
important to prevent serious damage to the
battery cells.
Battery leakage may occur under extreme
usage or temperature conditions. Avoid
contact with skin and eyes. The battery
liquid is caustic and could cause chemical
burns to tissues. If liquid comes in contact
with skin, wash quickly with soap and water,
then with lemon juice or vinegar. If the liquid
contacts your eyes, flush them with water for
a minimum of 10 minutes and seek medical
attention.
Place charger on flat non-flammable
surfaces and away from flammable
materials when re-charging battery pack.
The charger and battery pack heat during
charging. Carpeting and other heat
insulating surfaces block proper air
circulation which may cause overheating of
the charger and battery pack. If smoke or
melting of the case are observed unplug the
charger immediately and do not use the
battery pack or charger.
Use of an attachment not recommended or sold by Bosch may result in a
risk of fire, electric shock or injury to
persons.
Battery/Charger
Use thick cushioned gloves and limit the
exposure time by taking frequent rest
periods.Vibration caused by hammer-drill
action may be harmful to your hands and
arms.
Never place the tool down until the bit or
accessory have come to a complete stop.
When removing the bit from the tool avoid
contact with skin and use proper
protective gloves when grasping the bit or
accessory. Accessories may be hot after
prolonged use.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

Your tool is equipped with a forward/
reversing lever and trigger lock located
above the trigger (Fig. 1). 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. For
forward rotation, (with chuck pointed away
from you) move the lever to the far left. For
reverse rotation move the lever to the far
right. To activate trigger lock move lever to
the center off position.
Do not change direction of
rotation until the tool comes
to a complete stop. Shifting during rotation
of the chuck can cause damage to the tool.
The tool has an internal preset clutch. The
clutch is set such that sufficient force is
transmitted to the bit for most drilling
conditions but it will slip when bit binds in
the hole or the tool is overloaded. Be aware
that due to required clutch setting, you may
experience a torque reaction an instant
before the clutch slips. This torque reaction
will twist the body of the rotohammer in the
opposite direction as the bit rotates, i.e.,
counterclockwise. As clutch is slipping, the
bit will most likely stop rotating. When the
binding force on the bit is removed the
clutch automatically resets. If you
experience bit binding and clutch begins to
slip, immediately turn the tool "OFF" and
correct the condition leading to the bit
binding.
Your tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from the minimum to the
maximum nameplate RPM by the pressure
you apply to the trigger. Apply more
pressure to increase the speed and release
pressure to decrease speed. This accurate
speed control enables you to drill without
center punching. It also permits you to use
as a power screwdriver. Bits are available for
driving screws as well as running bolts and
nuts.

The battery is equipped with a charged
condition indicator. This indicator shows the
charged condition of the battery during the
working process.
By pressing the button ON, the charged
condition can also be checked when the
battery is removed or when the machine is
not in use. After approx. 4 seconds, the
charged indicator switches off automatically.
When the last indicating element blinks (0 10%), the battery is nearly discharged and
must be recharged.
To maintain the indicator accuracy,
occasionally discharge the battery until the
speed of the machine is distinctly reduced
and the charged condition indicator goes off
completely.
Disconnect battery pack
from tool or place the
switch in the locked or off position before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
Clean the insert shank end of the accessory
to remove any debris, then lightly grease
with a light oil or lubricant.
Insert accessory into the tool holder through
the dust shield, while twisting and pushing
inward until it locks automatically into place.
Pull outward on the accessory to be certain
it is locked into the tool holder.
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.
The selector dial allows the tool to be set for
various drilling applications. Shift the dial
right or left depending on the below
applications.
Do not operate the
selection dial until the tool
come to a complete stop. Shifting during
rotation of the chuck can cause damage to
the tool.
Do not use demolition or chipping bits such
as bull points, chisels, spades, gouges, etc.

RELEASING AND INSERTING BATTERY PACK
PROTECTIVE
CAP
BATTERY PACK
LOCKING BUTTON
Plug charger cord into your standard power
outlet, then insert battery pack into
charger.The charger’s green indicator light
will begin to “BLINK”. This indicates that the
battery is receiving a fast charge. Fastcharging will automatically stop when the
battery pack is fully charged.
When the indicator light stops “BLINKING”
(and becomes a steady green light) fast
charging is complete, and an acoustical
signal sounds for a period of approximately
2 seconds which indicates that the battery is
completely charged.
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.
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 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.
CHARGING BATTERY PACK

WARNING
BM 1619929426 8/01 8/2/01 1:19 PM Page 10
1. The battery pack accepts only about 80%
of its maximum capacity with its first few
charge cycles. However, after the first few
charge cycles, the battery will charge to full
capacity.
2. The charger was designed to fast charge
the battery only when the battery
temperature is between 32˚F (0˚C) and 140˚F
(60˚C). If the battery pack is too hot or too
cold, the charger will not fast charge the
battery. (This may happen if the battery pack
is hot from heavy use). When the battery
temperature returns to between 32˚F (0˚C)
and 140˚F (60˚C), the charger will
automatically begin charging.
3. 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.
4. If you anticipate long periods (i.e. a month
or more) of non-use of your tool, it is best to
run your tool down until it is fully discharged
before storing your battery pack. After a long
period of storage, the capacity at first
recharge will be lower. Normal capacity will
be restored in two or three charge/discharge
cycles. Remember to unplug charger during
storage period.
5. If battery does not charge properly:
a. Check for voltage at outlet by plugging
in some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power “off” when
lights are turned off.
IMPORTANT CHARGING NOTES
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 and is
being trickle charged.
If the green indicator light is
“BLINKING”, the battery pack is
being fast-charged. Fast-charging
will automatically stop when the
battery pack is fully charged.
If the red indicator light is “ON”,
the battery pack is too hot or cold
for fast-charging. The charger will
switch to trickle charge, until a
suitable temperature is reached, at which
time the charger will switch automatically to
fast-charging.
If the red indicator light is
“BLINKING”, an acoustical signal
will sound for a period of 2 seconds
which indicates 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.

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.
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 may void the warranty.
