Additional Safety Instructions - Hilti DD 120 Manual De Instrucciones

b) Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing
and gloves away from moving parts. Loose clothes,
jewelry or long hair can be caught in moving parts.
c) Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the switch
on invites accidents.
d) Remove adjusting keys or switches before turning
the tool on. A wrench or a key that is left attached
to a rotating part of the tool may result in personal
injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. Proper footing and balance en-
ables better control of the tool in unexpected situa-
tions.
f) Use safety equipment. Always wear eye protec-
tion.Dust mask, non-skid safety shoes, hard hat or
hearing protection must be used for appropriate con-
ditions.
5.1.4 Tool use and care
a) Use clamps or other practical way to secure and
support the workpiece to a stable platform. Hold-
ing the work by hand or against your body is unstable
and may lead to loss of control.
b) Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
c) Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
d) Disconnect the plug from the power source before
making any adjustments, changing accessories,
or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
e) Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
f) Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cut-
ting edges are less likely to bind and are easier to
control.
g) Check for misalignment or binding of moving
parts, breakage of parts and any other condition
that may affect the tool's operation. If damaged,
have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
h) Use only accessories that are recommended by
the manufacturer for your model. Accessories that
may be suitable for one tool may become hazardous
when used on another tool.
5.1.5 Service
a) Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
b) When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Mainte-
nance section of this manual. Use of unauthorized
parts or failure to follow Maintenance Instructions
may create a risk of electric shock or injury.

5.2 Additional safety instructions

Read all instructions before using this electric tool or
machine and keep the safety instructions in a safe
place.
5.2.1 Proper organization of the work area
a) Approval must be obtained from the site engineer
or architect prior to beginning drilling work. Drilling
work on buildings and other structures may influence
the statics of the structure, especially when steel
reinforcing bars or load-bearing components are cut
through.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
c) 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.
d) When drilling through walls, cover the area behind
the wall, as material or the core may fall out on
the other side of the wall. When drilling through
ceilings, secure (cover) the area below as drilled
material or the core may drop out and fall down.
e) Wear respiratory protection if the work causes
dust.
f) It is recommended that rubber gloves and non-
skid shoes are worn when working outdoors.
g) Do not allow other persons to touch the machine
or the extension cord.
h) Always lead the supply cord, extension cord and
water hose away from the tool or machine to the
rear to prevent a tripping hazard while working.
i) Keep the supply cord, extension cord, suction
hose and vacuum hose away from rotating parts.
j) CAUTION: Before beginning drilling, check that
there are no live electric cables located in the
base material.
k) Concealed electric cables or gas and water pipes
present a serious hazard if damaged while you
are working. Accordingly, check the area in which
you are working beforehand (e.g. using a metal
detector). External metal parts of the machine may
become live, for example, when an electric cable is
damaged accidentally.
l) Do not work from a ladder.
m) 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, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
