GeneralSafetyRules
Read all instructions. Failure to follow all instructions listed below may
__ result in electric shock, fire and/or serious injury. The term "power tool" in
all of the warnings listed below refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESEINSTRUCTIONS
Work area safety
Keep work area clean and well lit.
Cluttered or 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 children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of
electric shock.
Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators. There
is an increased risk of electric shock if your
body is earthed or grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric
shock.
When operating a power tool outdoors,
use an extension cord suitable for
outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric
shock.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a
hazard to the operator.
if operating the power tool in damp
locations is unavoidable a Ground Fault
Circuit Interrupter (GFCI) must be used to
supply the power to your tool. GFCI and
personal protection devices like electrician's
rubber gloves and footwear will further
enhance your personal safety.
Personal safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use apower tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating power tools may
result in serious personal injury.
Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
Avoid accidental starting. Ensure the
switch is in the off=position before
plugging in. Carrying power tools with your
finger on the switch or plugging in power
tools that have the switch on invites
accidents.
Remove any adjusting key or wrench
before turning the power tool on. A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unexpected
situations.
Dress properly. Do not wear loose
clothing or jewelry. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
if devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of these devices can reduce dust-
related hazards.
-2-

Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Power tool use and care
Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was
designed.
Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any
adjustments, changing accessories, or
storing power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tools operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
SAVE THESE
cutting edges are less likely to bind and are
easier to control.
Use the power tool, accessories and tool
bits etc., in accordance with these
instructions and in the manner intended
for the particular type of power tool,
taking into account the working
conditions and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
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.
Service
Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Develop aperiodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the tool since internal wires may be
misplaced or pinched or safety guard
return springs may be improperly
mounted. Certain cleaning agents such as
gasoline, carbon tetrachloride, ammonia, etc.
may damage plastic parts.
Risk of injury to user, power cord must only be
serviced by a Bosch Factory Service Center
or Authorized Bosch Service Station.
INSTRUCTIONS
Rotary Hammer Safety Rules
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tools may contact hidden wiring
or its own cord. Contact with a "live" wire
will make exposed metal parts of the tool
"live" and shock the operator.
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 drill, fasten or break into existing
wails 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.
Use a metal detector to determine if there
are gas or water pipes hidden in the work
area or call the local utility company for
assistance before beginning the operation.
-3-

Striking or cutting into a gas line will result in
explosion. Water entering an electrical device
may cause electrocution.
Always use auxiliary handle for maximum
control over torque reaction or kick-back.
High torque 3/8" and larger chuck capacity
drills are equipped with auxiliary handles.
Always wear safety goggles or eye
protection when using this tool. Use a
dust mask or respirator for applications
which generate dust.
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.
Secure the material being drilled. Never
hold it in your hand or across legs.
Unstable support can cause the drill bit to
bind causing loss of control and injury.
Never leave the trigger locked "ON".
Before plugging the tool in, check that the
trigger lock is "OFF". Accidental start-ups
could cause injury.
Position the cord clear of rotating bit. Do
not wrap the cord around your arm or
wrist. If you lose control and have the cord
wrapped around your arm or wrist it may
entrap you and cause injury.
Position yourself to avoid being caught
between the tool or side handle and walls
or posts. Should the bit become bound or
jammed in the work, the reaction torque of
the tool could crush your hand or leg.
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 drill body will tend to
twist in the opposite direction as the drill bit is
rotating.
Do not grasp the tool or place your hands
too close to the spinning chuck or drill
bit. Your hand may be lacerated.
When installing adrill bit, insert the shank
of the bit well within the jaws of the
chuck, if the bit is not inserted deep
enough, the grip of the jaws over the bit is
reduced and the loss of control is increased.
Do not use dull or damaged bits and
accessories. Dull or damaged bits have a
greater tendency to bind in the workpiece.
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.
Check to see that keys and adjusting
wrenches are removed from the drill
before switching the tool "ON". Keys or
wrenches can fly away at high velocity
striking you or a bystander.
Do not run the drill while carrying it at
your side. A spinning drill bit could become
entangled with clothing and injury may result.
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.

Dust ExtractJoR
Do not drill into metal with
the dust extraction system
mounted. Hot metal chips can self-ignite or
igniteparts of the dust extraction system.
Do not drill into wood with
dust extraction system
mounted. Wood chips are typically too large
andwill clog the dust channel.
Your tool is equipped with
a dust canister, empty it
frequently, after completion of drilling and
before storing the tool. Be extremely
careful of dust disposal, materials in fine
particle form may be explosive.
Note: Do not use the dust extraction system
when chiselling, screwdriving or cuttingthreads.
The dust extraction system retracts during
operation so that the dust cap is always kept
close to surface being drilled.
The dust extraction system automatically
switches on and off with the power tool.
For maximum dust extraction efficiency, please
observe the following.
* The drill bit being used may not project
beyond the dust cap as shown in figures 13 &
14. (Example for an SDS-plus drill bit: Max.
total length approx. 160 mm, working length
approx. 100 mm).
* Pay attention that the dust cap faces flush
against the workpiece or the wall. At the same
time, this makes working at a right angle easier.
* After reaching desired drilling depth, first pull
the drill bit out of the hole and then switch the
tool off.
* Check the condition of the microfilter regularly.
Replace a damaged microfilter immediately.

Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
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 (Fig. 1).
REVERSING SWITCH LEVER
This tool is equipped with a rotating brush
reversing system. This results in longer tool life
while maximizing power in both forward and re- REVERSING
verse directions. The reverse switch can be SWITCH
operated from either the right or left side of the LEVER
tool.
FOR FORWARD ROTATION: slide switch to
arrow marked forward (Fig. 13).
FOR REVERSE ROTATION: slide the slide
switch to arrow marked reverse. NOTE: Tool
will not operate in middle position.
SLiP CLUTCH
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 rotary hammer 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.
-11-

DRILL/HAMMER DRILL SELECTION DiAL
The selector dial allows the tool to be set for
various drilling/hammer drilling applications.
Depress release button and turn selector 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.
Drill only action: For drilling in
woods, metals, plastics or
other non concrete materials.
Drill with hammer action: For
drilling in concrete, asphalt,
tile or other similar hard
materials.
Following a few simple tips will reduce wear
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.
All hammers require a short period of time to
warm up. Depending on the room
temperature, this time may vary from
approximately 15 seconds (90°F) to 2
minutes (322). A new hammer requires a
break-in period before full performance is
realized. This period may require up to 5
hours of operation.
Carbide tipped bits: Used for drilling stone,
concrete, cement, brick, cinder block and
other unusually hard non-metals. The Rotary
Hammer is designed for "SDS" Carbide
Tipped Bits up to 3/4 inch diameter.
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
Do not drill into wood with
dust extraction system
mounted. Wood chips are typically too large
and will clog the dust channel.
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
Do not drill into metal with
the dust extraction system
mounted. Hot metal chips can self-ignite or
ignite parts of the dust extraction system.
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.
-12-

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
skipping.
Maintenance
Service
_Preventive maintenance
performed by unauth-
orized personnel may result in misplacing
of internal wires and components which
could cause serious hazard. We
recommend that all tool service be performed
by a Bosch Factory Service Center or Autho-
rized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
Only genuine Bosch replacement brushes
specially designed for your tool should be
used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
disconnect the tool from
the power supply before cleaning or
performing any maintenance. 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 openings.
_ 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.
Extension Cords
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.

etyes bras.
AssujettissezI'ouvrage _porter. Ne le tenez jamais
dans votre main ou par-dessus yes jambes. Un
support instable peut faire gripper le foret,
provoquant ainsi une perte de contr6le et des
blessures.
Ne tenez jamais la g_chette bloqu_e en position de

Eninstallant un foret, ins_rez la tige du foret bien
I'int_rieur des m_choires du mandrin. Sile foret
n'est pas ins_r_ assez profond_ment, la prise des
m_choires sur le foret est r_duite et la perte de
