Drill Safety Warnings; Additional Safety Rules - Hilti DD 150-U Mode D'emploi

5.1.5 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.

5.2 Drill safety warnings

a) Wear ear protectors when impact drilling. Expos-
ure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory 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.

5.3 Additional safety rules

5.3.1 Personal safety
a) During hand-held use, always hold the machine
securely with both hands on the grips provided.
Keep the grips dry, clean and free from oil and
grease.
b) Check that the side handle is tightened securely.
c) Assemble the parts of the mounting device cor-
rectly before attaching the machine. In order to
avoid the risk of collapse, it is important that the
parts are assembled correctly.
d) Attach the machine to the mounting device se-
curely before beginning use. Movement of the ma-
chine on the mounting device could lead to loss of
control.
e) Place the mounting device on a solid, flat and level
surface. If the mounting device can slip or wobble,
the machine cannot be guided smoothly and safely.
Check the nature of the surface. Rough surfaces
f)
may reduce holding power. Coatings or composite
materials may pull away from the surface while you
are working.
g) Do not overload the mounting device and do not
use it as a substitute for a ladder or platform.
Overloading the mounting device or standing on it
may shift its center of gravity to a higher position,
causing it to tip over.
h) Respiratory protection must be worn if the ma-
chine is used without a dust extraction system for
work that creates dust.
Improve the blood circulation in your fingers by
i)
relaxing your hands and exercising your fingers
during breaks between working.
j) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially ro-
tating drill bits, discs or blades, etc. may lead to
injury.
k) When using the equipment, always lead the supply
cord, the extension cord and the water hose (if
applicable) away from the machine to the rear.
This will reduce the risk of tripping and falling over
the cord or hose while working.
l) Avoid skin contact with drilling slurry.
m) Wear protective gloves when changing core bits.
The core bit may become hot during use.
n) Children must be instructed not to play with the
machine.
o) The machine is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
p) Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Material
containing asbestos must only be treated by special-
ists. Where the use of a dust extraction device is
possible it shall be used. To achieve a high level
of dust collection, use a suitable vacuum cleaner
of the type recommended by Hilti for wood dust
and/or mineral dust together with this tool. Ensure
that the workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended. Fol-
low national requirements for the materials you
want to work with.
5.3.2 Power tool use and care
a) Secure the workpiece. 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 machine.
b) Check that the core bits used are compatible with
the chuck system and that they are secured in the
chuck correctly.
c) Switch the machine off and unplug the supply
cord in the event of a power failure or interruption
in the electric supply. This will prevent accidental
restarting when the electric power returns.
5.3.3 Electrical safety
a) Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the machine may
become live, for example, when an electric cable is
damaged accidentally. This presents a serious risk of
electric shock.
b) Never operate the machine without the supplied
PRCD (machines without PRCD: Never operate
the machine without an isolating transformer).
Test the PRCD each time before use.
