General Power Tool Safety
Warnings
en
WARNING Read all safety warnings and all
instructions. Failure to follow the
warnings 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.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d) 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 and moving parts. Damaged or entangled cords increase the risk
of electric shock.
1 619 929 720 | (14.8.07)
e) 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.
f) If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an
RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and
use common sense when operating a
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.
b) 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.
c) 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 energising power tools that
have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing
and balance at all times. This enables better control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
Bosch Power Tools
English | 15
g) 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 dust-related hazards.
5) Service
a) 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.
4) Power tool use and care
a) 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.
b) 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.
Machine-specific
Safety Warnings
f Wear hearing protection. Exposure to noise
can cause hearing loss.
f Always use the auxiliary handle supplied
with the machine. Loss of control can cause
personal injury.
c) 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.
f Use suitable detectors to determine if utility
lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric
shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property
damage or may cause an electric shock.
d) 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.
f Hold the power tool only by the insulated
gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a
“live” wire will also make exposed metal parts
of the power tool “live” and shock the operator.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) 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.
Bosch Power Tools
f When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
f Do not work materials containing asbestos.
Asbestos is considered carcinogenic.
f Take protective measures when dust can develop during working that is harmful to one’s
health, combustible or explosive. Example:
Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip extraction when connectable.
1 619 929 720 | (14.8.07)
16 | English
f Always wait until the machine has come to a
complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
f Never use the machine with a damaged cable. Do not touch the damaged cable and pull
the mains plug when the cable is damaged
while working. Damaged cables increase the
risk of an electric shock.

Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the product are: Sound pressure level 90 dB(A); Sound
power level 101 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) determined according to EN 60745:
Hammer drilling into concrete: Vibration emission value ah =13 m/s2, Uncertainty K=1.5 m/s2,
Chiselling: Vibration emission value ah =11 m/s2,
Uncertainty K=1.5 m/s2.
The vibration emission level given in this information sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another. It
may be used for a preliminary assessment of exposure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly
increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times
when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.

Operation
Switching On/Off in Chiselling Mode
Starting Operation
f Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
Setting the Operating Mode
To start the machine, press the On/Off switch 5
at the top (I) until it locks.
The operating mode of the power tool is selected
with the mode selector switch 3.
To switch off the machine, press the On/Off
switch 5 at the bottom (0) and release it.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine
can be damaged.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a certain time.
Turn the mode selector switch 3 to the requested
position.
Setting the Speed/Impact Rate
Position for hammer drilling
When the drilling tool does not immediately rotate upon switching on,
allow the machine to run slowly until the drilling tool rotates.
Vario-Lock position for adjustment
of the chiselling position
The electronic control enables stepless speed
and impact preselection in accordance with the
material to be worked.
The constant electronic control keeps the preselected speed and impact rate nearly constant between no-load and load conditions.
The maximum hammering capacity is achieved
when the thumbwheel 6 is set to position “6”.
For lower speed settings, the hammering capacity is lower due to technical reasons.
Select the speed with the thumbwheel 6 according to the material.
Position for chiselling
When plugging the plug into the socket outlet or
after a power failure, the constant electronic
control automatically sets the highest speed and
impact rate. This ensures working at optimum
performance despite too low preadjustment of
the thumbwheel 6.
In the “chiselling” position, the impact rate
preselected with the thumbwheel 6 is automatically increased when switching on; this causes
the power tool to operate with increased capacity when chiselling.
The data in the following table are recommended
values.
