Personal Protective Equipment - Hilti DG 150 Manual De Instrucciones

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) Dust from material such as paint containing lead,
some wood species, minerals and metal may be harm-
ful. 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 clas-
sified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood con-
ditioning (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. Follow nation-
al requirements for the materials you want to work
with.

5.3.2 Personal protective equipment

a) Always wear eye protection, a safety helmet, ear pro-
tection, safety gloves, breathing protection and pro-
tective clothing when grinding.
b) Wear knee protectors when working on floors.
