employer about the symptoms and consult a qualified
physician.
For pneumatic chisel hammers:
Never use the chisel as a hand tool. The chisels are heat-
treated and can break.
For pneumatic chisel hammers:
Use only sharp chisels. Dull application tools can lead to
heavy vibrations and fatigue breakage.
For pneumatic chisel hammers:
Do not use the chisel as a lever. Otherwise, it can break.
Never cool off hot accessories in water. This can lead to
brittleness and premature failure.
Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany 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 dam-
age.
Avoid contact with "live" conductors. The pneumatic
tool is not insulated; contact with a "live" conductor can
lead to an electric shock.
The dust developing during sanding,
WARNING
sawing, grinding, drilling and similar
operations can act carcinogenic, teratogenic or mutagen-
ic. Some of the substances contained in these dusts are:
–
Lead in lead-based paints and varnishes;
–
Crystalline silica in bricks, cement and other masonry
work;
–
Arsenic and chromate in chemically treated wood.
The risk of disease depends on how often you are exposed to
these substances. To reduce the risk, you should work only in
well ventilated rooms with appropriate protective equipment
(e. g. with specially designed respirators that filter out even
the smallest dust particles).
Wear ear protectors. Exposure to noise can cause hear-
ing loss.
When working on the workpiece, additional noise can
develop, which can be avoided through appropriate
measures (e. g. by using damping materials on occur-
rence of ringing noise from the workpiece).
Operate the pneumatic tool in such a manner that as lit-
tle dust as possible develops, e. g. through moistening
the material being worked.
When the pneumatic tool is equipped with a silencer,
always ensure that it is available and in proper working
condition when operating the pneumatic tool.
Vibration effects may cause damage to the nerves and
blood circulation disorders in the hands and arms.
Wear close-fitting gloves. The flow of compressed air
makes the handles of pneumatic tools cold. Warm hands
are less sensitive to vibrations. Loose fitting gloves can be
caught by rotating parts.
If you notice that the skin of your fingers or hands be-
comes numb, tingles, hurts or turns white, stop work-
ing with the pneumatic tool, notify your employer and
consult a physician.
Bosch Power Tools
Do not hold the application tool while working.
Hold the pneumatic tool with a not too firm yet secure
grip, compliant with the required hand-reaction forces.
The vibrations can be intensified the firmer you hold the
tool.
When universal rotary couplings (bayonet couplings)
are being used, retaining pins are required. Use Whip-
check hose restraints to protect against failed hose
connections or the connection between hose and pneu-
matic tool.
Never carry the pneumatic tool by the hose.
Symbols
The following symbols could have a meaning for the use of
your pneumatic tool. Please take note of the symbols and
their meaning. The correct interpretation of the symbols will
help you to use the pneumatic tool in a better and safer man-
ner.

Meaning
Before installing, operating, re-
pairing, maintaining and replacing
accessories as well as prior to
working near by the pneumatic
tool, please read and observe all in-
structions. Failure to follow the fol-
lowing safety warnings and instruc-
tions may result in serious injury.
Wear ear protectors. Exposure to
noise can cause hearing loss.
