Personal Protective Equipment - Hilti DG 150 Mode D'emploi

e) Improve the blood circulation in your fingers by relax-
ing your hands and exercising your fingers during
breaks between working.
f) Check each time before using the power tool, includ-
ing after work breaks, that the wheel is fitted secure-
ly.
-CAUTION-
The rotating wheel presents a risk of injury. Accord-
ingly, operate the power tool only when the wheel
is directed toward the workpiece.
g) Use clamps or a vice to secure loose workpieces.
h) Take care to avoid concealed electric cables, gas and
water pipes. Check the working area, e.g. using a met-
al detector.
i) Sparks may fly when grinding. Take care to ensure
that flying sparks do not present a hazard to other per-
sons.
j) Conductive dust may collect inside the tool when
grinding conductive materials. This may have a neg-
ative effect on the insulation of the tool and cause
electric shocks. As a result, tools used for this appli-
cation must be checked by a technical specialist or
Hilti service department at least every six months to
ensure integrity of the insulation and to check for pos-
sible accumulation of conductive dust or other con-
ductive substances.
k) -CAUTION- The tool continues to run for approx. 2
seconds after switching off.
l) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
m)Children must be instructed not to play with the
tool.
n) Observe the direction-of-rotation arrow when fitting
a wheel.
o) Do not touch the supply cord in the event of it becom-
ing damaged while working. Disconnect the supply
cord plug from the socket.
p) Test new wheels by running them at maximum no-
load speed for at least 30 seconds.
q) - WARNING - Do not disconnect the plug of the DG150
from the power unit DPC20 under load.
r) Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with
a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
s) The diamond cup wheel, parts of the guard or the tool
(gearing section) may become hot during operation.

To avoid burns, do not touch these parts with the bare
hands. Wear safety gloves.
t) Connect the tool to the industrial vacuum cleaner.
u) Unless stated otherwise in the operating instructions,
damaged protective equipment and parts must be cor-
rectly repaired or replaced at an accredited service
workshop.
v) For safety reasons, the tool may be operated only when
the guard and when safety gloves are worn.
w)The guard may be adjusted only when the tool has
been switched off and the supply cord unplugged.
Grinding may produce hazardous dust.
x) Before starting work, find out to which dangerous
material class the grinding dust produced belongs.
Use the tool in conjunction with an industrial vacuum
cleaner with an officially approved safety classifica-
tion and which complies with the local dust protec-
tion regulations.
y) When grinding, the industrial vacuum cleaner used
must be equipped with a filter suitable for the appli-
cation.
z) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crystalline
silica from bricks, concrete and other masonry prod-
ucts and natural stone, arsenic and chromium from
chemically treated lumber. Your risk from these expo-
sures 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 equip-
ment, such as respiratory protection appropriate
for the type of dust generated, and designed to fil-
ter 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 pro-
mote absorption of harmful chemicals.
