General Safety Rules - Hilti DD 350-CA Manual De Instrucciones

g) Wear respiratory protection if the work causes
dust.
h) Ensure that the workplace is well ventilated.
i) It is recommended that rubber gloves and non-
skid shoes are worn when working outdoors.
j) Keep the supply cord, extension cord, suction
hose and vacuum hose away from rotating parts.
k) Don't work from a ladder.
l) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
m) 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.
n) Always lead the supply cord and extension cord
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.

4.2.1 General safety rules

a) Fit the protective cover cap only when the drilling
feed unit is unplugged. Operate the core drilling
machine only when the connecting socket is
covered, i.e.when the protective cover cap is fit-
ted. If the protective cover cap is missing, contact
Hilti Service and obtain a replacement. Unplug the
core drilling machine from the electric supply im-
mediately if water enters the connecting socket.
Check to ensure that the connecting socket is
dry before making further use of the core drilling
machine. The connecting socket may fill with water
if it is not covered by the protective cap or if the
connecting plug is not in place, resulting in a risk of
electric shock if the parts are touched.
b) Keep the grips dry, clean and free from oil and
grease.
c) Never leave the machine unattended.
d) Store machines in a secure place when not in use.
When not in use, machines must be stored in a
dry, high place or locked away out of reach of
children.
e) Children must be instructed not to play with the
machine.
f) The machine is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
g) 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.
h) Tampering with or modification of the machine, drill
stand and accessories is strictly prohibited.
Check the machine and its accessories for any
i)
damage. Guards, safety devices and any slightly
damaged parts must be checked carefully to en-
sure that they function faultlessly and as inten-
ded. Check that moving parts function correctly
without sticking and that no parts are damaged.
All parts must be fitted correctly and fulfill all
conditions necessary for correct operation of the

other parts must be repaired or replaced properly
at an authorized service center unless otherwise
indicated in the operating instructions.
Regularly check the hoses for damage and make
sure that the maximum permissible water supply
pressure of 6 bar is not exceeded.
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.
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-
