Drill Safety Warnings; Additional Safety Instructions - Hilti SF 144-A Manual De Instrucciones

c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
en
d) Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.

5.2 Drill safety warnings

a) Wear ear protectors when impact drilling. Expo-
sure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring. Contact with a
"live" wire will make exposed metal parts of the tool
"live" and shock the operator.

5.3 Additional safety instructions

5.3.1 Personal safety
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener
may contact hidden wiring. Fasteners contacting
a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
b) Keep the grips dry, clean and free from oil and
grease.
c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
d) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
e) Activate the safety lock (forward / reverse switch
in the middle position) before storing or trans-
porting the power tool.
f) Children must be instructed not to play with the
power tool.
g) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
h) 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-
6
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
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
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,
eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
5.3.2 Power tool use and care
a) 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 power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.3.3 Battery tool use and care
a) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
c) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk
of fire and explosion.
d) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
e) Avoid short-circuiting the battery. Check that the
terminals on the battery and in the power tool
are free from foreign objects before inserting the
battery in the power tool. Short circuiting the bat-
tery terminals presents a risk of fire, explosion and
chemical burns.
Do not charge or continue to use damaged bat-
f)
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
5.3.4 Electrical safety
Before beginning work, check the working area (e.g.
using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the power tool may become
