General Power Tool Safety Warnings
Read all safety warnings and all instructions. Failure to follow the warnings
! WARNING and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work area safety
power tool. Do not use a power 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.
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.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and / or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
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.
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.
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 overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
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.
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.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dustrelated hazards.
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.
Power tool use and care
If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduces the risk of electric shock.
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.
Personal safety
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.
Stay alert, watch what you are doing and
use common sense when operating a
-2-
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.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp 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,
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.
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.
Service
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.
Many accidents are caused by poorly
maintained power tools.
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.
Demolition Hammer Safety Rules
Wear ear protectors. Exposure to noise can
cause hearing loss.
Always wear safety goggles or eye
protection when using this tool. Use a dust
mask or respirator for applications which
generate dust. Safety goggles or eye
protection will help deflect fragments of the
material that may be thrown toward your face
and eyes. Dust generated or gases released
from the material you are cutting (i.e. asbestos
insulated pipes, radon) may cause respiratory
difficulties.
Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
Hold power tools by insulated gripping
surfaces, when performing an operation
where the cutting tool may contact hidden
wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed
metal parts of the power tool "live" and could
give the operator an electric shock.
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.
Do not cut or drill into gas lines. Use a
metal detector to determine if there are
metal pipes hidden in the work area or call
the local utility company for assistance
before beginning the operation. Striking or
cutting into a gas line will result in explosion.
Always use the side handle for maximum
control over torque reaction or kick-back.
Never attempt to operate this tool with one
hand. The slip clutch engages if you firmly
control the tool during a torque reaction or
kickback.
-3-
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.
Do not strike the bit with a handheld
hammer or sledge hammer when
attempting to dislodge a bound or jammed
bit. Fragments of metal from the bit could
dislodge and strike you or bystanders.
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.
Never place the tool down until the motor
has come to a complete stop.
Do not use dull or damaged bits and
accessories. Dull or damaged bits have a
greater tendency to bind in the workpiece.
Additional Safety Warnings
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
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.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Some dust created by power
! WARNING 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 chemicallytreated lumber.
Develop a periodic 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. The power cord must only
be serviced by a Bosch Factory Service Center
or Authorized Bosch Service Station.
-4-
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.

Operating Instructions
PADDLE "ON/OFF" SWITCH
The paddle switch enables the operator to
control the switch functions of "ON /OFF".
TO SWITCH THE TOOL "ON": Squeeze
and hold the paddle lever. TO SWITCH THE
TOOL "OFF ": Release pressure on the
paddle lever. The switch is spring loaded and
will return automatically.
"TOOL TIPS"
The tool may be switched on with either hand. (32˚F). A new hammer requires a break-in

period may require up to 5 hours of operation.
For the best penetration rates in concrete, run
the tool with a steady pressure, but do not use
excessive force as this will decrease the
efficiency of the tool. Start chipping with the
tool in a straight in position until the surface to
be broken is chipped. Draw the hammer back
at an angle of 60˚ with the surface to be
broken. Apply only enough force to keep the
tool weight on the accessory
Avoid no load running of the tool. No load or
"empty blows" is the most damaging factor to
any impact hammer.
An electric hammer is likely to be the most
expensive portable tool at the construction job.
The long wear and efficient operation of the
BOSCH hammers will more than justify the
cost for tools of this type. As earlier pointed
out, sharp accessories as well as clean air
vents are necessary for efficient operation.
Establish and follow a set maintenance
program.
All grease packed 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
