General Safety Rules - Hilti DD 120 Mode D'emploi

this type of work. To reduce exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
en
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
nose, eyes, or to remain on your skin may promote
absorption of harmful chemicals.

5.2.2 General safety rules

a) Use the right tool or machine for the job. Do not
use the tool or machine for purposes for which
it was not intended. Use it only as directed and
when in faultless condition.
b) Use the power tool, accessories and tool bits etc.
in accordance with these instructions taking into
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.
c) Use only the genuine Hilti accessories or ancillary
equipment listed in the operating instructions. Use
of accessories or ancillary equipment not listed in the
operating instructions may present a risk of personal
injury.
d) Keep the grips dry, clean and free from oil and
grease.
e) Never leave the machine unattended.
Store machines in a secure place when not in use.
f)
When not in use, machines must be stored in a
dry, high place or locked away out of reach of
children.
g) Always disconnect the supply cord from the elec-
tric supply when the machine is not in use (e.g.
during breaks between working), before making
adjustments, before carrying out care and mainte-
nance and before changing core bits. This safety
precaution prevents the machine starting uninten-
tionally.
h) Keep children away. Keep other persons away
from the working area.
Children must be instructed not to play with the
i)
machine.
j) The machine is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
k) Never operate the machine without the GFCI sup-
plied with it. Test the GFCI each time before use.
l) Check the machine and its accessories for any
damage. Guards, safety devices and any slightly
damaged parts must be checked carefully to en-
sure that they function faultlessly and as intended.
Check that moving parts function correctly with-
8
out sticking and that no parts are damaged. All
parts must be fitted correctly and fulfill all condi-
tions necessary for correct operation of the ma-
chine. Damaged guards, safety devices and other
parts must be repaired or replaced properly at an
authorized service center unless otherwise indi-
cated in the operating instructions.
m) Avoid skin contact with drilling slurry.
n) Wear a protective mask during work that gen-
erates dust, e.g. dry drilling. Connect a dust re-
moval system. Drilling in materials hazardous to
the health (e.g. asbestos) is not permissible.
5.2.3 Mechanical
a) Follow the instructions concerning care and main-
tenance.
b) Follow the instructions concerning lubrication
and changing core bits.
c) Check that the core bits used are compatible with
the chuck system and that they are secured in the
chuck correctly.
d) Make sure that the machine is correctly and se-
curely mounted on the drill stand.
e) Do not touch rotating parts.
Check that all the clamping screws are correctly
f)
tightened.
g) Make sure that the cover with built-in end stop
is always fitted to the drill stand. The safety-
relevant end-stop function becomes inoperative
if this component is not fitted.
5.2.4 Electrical
a) Check the condition of the machine and its ac-
cessories. Do not operate the machine and its
accessories if damage is found, if the machine is
incomplete or if its controls cannot be operated
faultlessly.
b) Do not touch the supply cord or extension cord
if it is damaged while working. Disconnect the
supply cord plug from the power outlet.
c) Damaged or faulty switches must be replaced at
a Hilti service center. Do not use the machine if it
cannot be switched on and off correctly.
d) Have the machine repaired only by a trained elec-
trical specialist (Hilti service center) using genuine
Hilti spare parts. Failure to observe this point may
result in risk of accident to the user.
e) Check the machine's supply cord at regular inter-
vals and have it replaced by a qualified specialist
if found to be damaged. Check extension cords
