Specific Safety Rules And Symbols; General Safety Precautions - Hilti ST 2500 Manual De Instrucciones

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

3. Specific safety rules and symbols

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.
WARNING: Some dust created by grinding, sanding,
cutting and drilling contains chemicals known to
cause cancer, birth defects, infertility or other repro-
ductive harm; or serious and permanent respiratory
or other injury. Some examples of these chemicals
are: lead from leadbased paints, crystalline silica from
bricks, concrete and other masonry products and nat-
ural stone, arsenic and chromium from chemical-
lytreated lumber. Your risk from these exposures varies,
depending on how often you do this type of work. To
reduce exposure to these chemicals, the operator
and bystanders should work in a well-ventilated area,
work with approved safety equipment, such as res-
piratory protection appropriate for the type of dust
generated, and designed to filter out microscopic
particles and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protective
clothing and wash exposed areas with soap and water.
Allowing dust to get into your mouth, eyes, or to remain
on your skin may promote absorption of harmful chem-
icals.
The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
Children must be instructed not to play with the tool.
3.1 Take the necessary precautions to make the
workplace safe
Ensure that the workplace is well ventilated.
●
Keep the workplace tidy. Objects which could cause
●
injury should be removed from the working area. Untidi-
ness at the workplace can lead to accidents.

account the working conditions and the work to
be performed. Use of the power tool for opera-
tions different from those intended could result in
a hazardous situation.
2.1.5 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.
Use clamps or a vice to secure the workpiece. The
●
workpiece is thus held more securely than by hand
and both hands remain free to operate the tool.
Avoid unfavorable body positions when working. Work
●
from a secure stance and always stay in balance.
To avoid tripping and falling when working, always lead
●
the supply cord, extension cord and extraction hose
away to the rear.
Concealed electric cables or gas and water pipes pre-
●
sent a serious hazard if damaged while you are working.
Accordingly, check the area in which you are working
beforehand (e.g. using a metal detector). Avoid con-
tact between your body and earthed / grounded objects,
such as pipes or radiators. External metal parts of the
tool may become live, for example, when an electric
cable is drilled into inadvertently.

3.2 General safety precautions

Use the right electric tool for the job. Do not use the
●
tool for purposes for which it was not intended. Use
the tool only as directed and when it is in faultless con-
dition.
Avoid contact with rotating parts.
●
Take the influences of the surrounding area into account.
●
Do not expose the tool to rain or snow and do not use
it in damp or wet conditions. Do not use the tool where
there is a risk of fire or explosion.
Keep the grips dry, clean and free from oil and grease.
●
When not in use, the tool must be stored in a dry place,
●
locked up or out of reach of children.
Disconnect the supply cord plug from the socket when
●
the tool is not in use (e.g. during breaks, before main-
tenance and before changing insert tools).
Switch the tool off before transporting it.
●
Check the electric tool for possible damage. Protec-
●
tive devices and any parts that may have suffered slight
damage should be checked for correct operation and
functionality before further use of the electric tool.
