5 Safety instructions
NOTE
The safety rules in section 5.1 contain all general safety
rules for power tools which, in accordance with the
applicable standards, require to be listed in the operating
instructions. Accordingly, some of the rules listed may
not be relevant to this tool.
5.1 General power tool safety warnings
a)
WARNING
Read all safety warnings and instructions. Failure
to follow the warnings and instructions may result
in electric shock, fire and/or serious injury. Save all
warnings and instructions for future reference.
en

Printed: 08.07.2013 | Doc-Nr: PUB / 5070634 / 000 / 01

The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
5.1.1Workareasafety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
5.1.2 Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Un-
modified plugs and matching outlets will reduce risk
of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
theriskofelectricshock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
5.1.3 Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch
is in the off‐position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turn-
ing the power tool on. A wrench or a key left at-
tached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
5.1.4 Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) 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.
5.1.5 Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
en

Printed: 08.07.2013 | Doc-Nr: PUB / 5070634 / 000 / 01

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.
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-
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.
f) Do not charge or continue to use damaged bat-
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

- For best results, batteries should be stored fully charged
in a cool dry place. Avoid charging the battery in places
subject to high ambient temperatures (e.g. at a window)
as this has an adverse effect on battery life and increases
the rate of self-discharge.

5 Consignes de sécurité
REMARQUE
Les indications de sécurité du chapitre 5.1 contiennent
toutes les indications générales de sécurité pour les ap-
pareils électriques qui, selon les normes applicables, sont
traitées dans le présent mode d'emploi. Par conséquent,
il est possible que certaines indications ne se rapportent
pas à cet appareil.
5.1 Indications générales de sécurité pour les
appareils électriques
a)
AVERTISSEMENT
Lire et comprendre toutes les consignes de sécu-
rité et instructions. Le non-respect des consignes
de sécurité et instructions indiquées ci-après peut
entraîner un choc électrique, un incendie et / ou de
graves blessures sur les personnes. Les consignes
de sécurité et instructions doivent être intégra-
lement conservées pour les utilisations futures.
La notion d’« outil électroportatif » mentionnée dans
les consignes de sécurité se rapporte à des outils
électriques raccordés au secteur (avec câble de rac-
cordement) et à des outils électriques à batterie (sans
câble de raccordement).
5.1.1 Sécurité sur le lieu de travail
a) Maintenez l’endroit de travail propre et bien
éclairé. Un lieu de travail en désordre ou mal éclairé
augmente le risque d’accidents.
b) N'utilisez pas l'outil électroportatif dans un envi-
ronnement présentant des risques d’explosion et
où se trouvent des liquides, des gaz ou poussières
inflammables. Les outils électroportatifs génèrent
des étincelles risquant d’enflammer les poussières
ou les vapeurs.
c) Tenez les enfants et autres personnes éloignés
durant l’utilisation de l’outil électroportatif. En cas
d’inattention vous risquez de perdre le contrôle de
l’appareil.
5.1.2 Sécurité relative au système électrique
a) La fiche de secteur de l’outil électroportatif doit
être appropriée à la prise de courant. Ne modifiez
en aucun cas la fiche. N'utilisez pas de fiches
d’adaptateur avec des outils électroportatifs avec
miseàlaterre.Lesfichesnonmodifiéesetlesprises
de courant appropriées réduisent le risque de choc
électrique.
b) Évitez le contact physique avec des surfaces
mises à la terre tels que tuyaux, radiateurs, cui-
sinières et réfrigérateurs. Il y a un risque élevé de
choc électrique au cas où votre corps serait relié à la
terre.
c) N'exposez pas les outils électroportatifs à la pluie
ou à l’humidité. La pénétration d’eau dans un outil
électroportatif augmente le risque d’un choc élec-
trique.
d) N'utilisez pas le câble à d’autres fins que celles
prévues, n'utilisez pas le câble pour porter l'ou-
til électroportatif ou pour l’accrocher ou encore
pour le débrancher de la prise de courant. Mainte-
nez le câble éloigné des sources de chaleur, des
parties grasses, des bords tranchants ou des par-
ties de l’appareil en rotation. Un câble endommagé
outorsadéaugmentelerisqued’unchocélectrique.
e) Au cas où vous utiliseriez l’outil électroportatif à
l’extérieur, utilisez uniquement une rallonge ho-
mologuée pour les applications extérieures. L’uti-
lisation d’une rallonge électrique homologuée pour
les applications extérieures réduit le risque d’un choc
électrique.
f) Si l'utilisation de l'outil électroportatif dans un
environnement humide ne peut pas être évitée,
un interrupteur de protection contre les courants
de court-circuit doit être utilisé. L'utilisation d'un
tel interrupteur de protection réduit le risque d'une
décharge électrique.
5.1.3 Sécurité des personnes
a) Restez vigilant, surveillez ce que vous faites.
Faites preuve de bon sens en utilisant l’outil
électroportatif. N'utilisez pas l'outil électropor-
tatif lorsque vous êtes fatigué ou après avoir
consommé de l’alcool, des drogues ou avoir pris
des médicaments. Un moment d’inattention lors de
l’utilisation de l'outil électroportatif peut entraîner de
graves blessures sur les personnes.
b) Portez des équipements de protection. Portez
toujours des lunettes de protection. Le fait de
porter des équipements de protection personnels tels
que masque anti-poussière, chaussures de sécurité
antidérapantes, casque de protection ou protection
acoustique suivant le travail à effectuer, réduit le
risque de blessures.
c) Évitez une mise en service par mégarde. S'as-
surer que l'outil électroportatif est arrêté avant
de le brancher à la source de courant et/ou au
bloc-accu, de le prendre ou de le porter. Le fait
de porter l'outil électroportatif avec le doigt sur l’in-
terrupteur ou de brancher l’appareil sur la source
de courant lorsque l’interrupteur est en position de
fonctionnement, peut entraîner des accidents.
d) Enlevez tout outil de réglage ou toute clé avant de
mettre l'outil électroportatif en fonctionnement.
Unecléouunoutilsetrouvantsurunepartieen
rotation peut causer des blessures.
e) Adoptez une bonne posture. Veillez à garder tou-
jours une position stable et équilibrée. Ceci vous
permet de mieux contrôler l'outil électroportatif dans
des situations inattendues.
f) Portez des vêtements appropriés. Ne portez pas
de vêtements amples ni de bijoux. Maintenez che-
veux, vêtements et gants éloignés des parties de
l’appareil en rotation. Des vêtements amples, des
bijoux ou des cheveux longs peuvent être happés
par des pièces en mouvement.
g) Si des dispositifs servant à aspirer ou à recueillir
les poussières doivent être utilisés, vérifiez que
fr
16
Printed: 08.07.2013 | Doc-Nr: PUB / 5070634 / 000 / 01

ceux-ci sont effectivement raccordés et qu’ils
sont correctement utilisés. L'utilisation d'un dis-
positif d'aspiration peut engendrer un risque à cause
des poussières.
5.1.4 Utilisation et maniement de l'outil
électroportatif
a) Ne surchargez pas l'appareil. Utilisez l’outil
électroportatif approprié au travail à effectuer.
Avec l'outil électroportatif approprié, vous
travaillerez mieux et avec plus de sécurité à la
vitesse pour laquelle il est prévu.
b) N'utilisez pas un outil électroportatif dont l’inter-
rupteur est défectueux. Un outil électroportatif qui
ne peut plus être mis en ou hors fonctionnement est
dangereux et doit être réparé.
c) Retirez la fiche de la prise de courant et/ou le
bloc-accu avant d'effectuer des réglages sur l'ap-
pareil, de changer les accessoires, ou de ranger
l'appareil. Cette mesure de précaution empêche une
mise en fonctionnement par mégarde de l'outil élec-
troportatif.
d) Gardez les outils électroportatifs non utilisés hors
de portée des enfants. Ne permettez pas l’utilisa-
tion de l’appareil à des personnes qui ne se sont
pas familiarisées avec celui-ci ou qui n’ont pas
lu ces instructions. Lesoutilsélectroportatifssont
dangereux lorsqu’ils sont utilisés par des personnes
non initiées.
e) Prendre soin des outils électroportatifs. Vérifier
que les parties en mouvement fonctionnent cor-
rectement et qu’elles ne sont pas coincées, et
contrôler si des parties sont cassées ou endom-
magées de sorte que le bon fonctionnement de
l’outil électroportatif s’en trouve entravé. Faire
réparer les parties endommagées avant d’utiliser
l'appareil. De nombreux accidents sont dus à des
outils électroportatifs mal entretenus.
f) Maintenez les outils de coupe aiguisés et propres.
Des outils soigneusement entretenus avec des bords
tranchants bien aiguisés se coincent moins souvent
et peuvent être guidés plus facilement.
g) L'outil électroportatif, les accessoires, les outils
à monter, etc. doivent être utilisés conformément
à ces instructions. Tenez compte également des
conditions de travail et du travail à effectuer. L’uti-
lisation des outils électroportatifs à d’autres fins que
celles prévues peut entraîner des situations dange-
reuses.
5.1.5 Utilisation et maniement de l'outil sur accu
a) Ne chargez les accumulateurs que dans des char-
geurs recommandés par le fabricant. Si un char-
geur approprié à un type spécifique d’accumulateurs
est utilisé avec des blocs-accus non recommandés
pour celui-ci, il y a risque d'incendie.
b) Dans les outils électroportatifs, n’utilisez que les
accumulateurs spécialement prévus pour celui-ci.
L’utilisation de tout autre accumulateur peut entraîner
des blessures et des risques d’incendie.
c) Tenez l’accumulateur non utilisé à l’écart de tous
objets métalliques tels qu’agrafes, pièces de
monnaie, clés, clous, vis ou autres, étant donné
qu’un pontage peut provoquer un court-circuit.
Un court-circuit entre les contacts d’accu peut
provoquer des brûlures ou un incendie.
d) En cas d’utilisation abusive, du liquide peut sortir
de l’accumulateur. Évitez tout contact avec ce
liquide. En cas de contact par mégarde, rincez
soigneusementavecdel’eau.Aucasoùleliquide
rentrerait dans les yeux, consultez en plus un
médecin. Le liquide qui sort de l’accumulateur peut
entraîner des irritations de la peau ou causer des
brûlures.
5.1.6 Service
a) Ne faire réparer l'outil électroportatif que par un
personnel qualifié et seulement avec des pièces
de rechange d’origine. Ceci permet d’assurer la
sécurité de l'outil électroportatif.
5.2 Indications de sécurité pour les perceuses
a) Porter un casque antibruit lors du perçage à per-
cussion. Le bruit peut entraîner des pertes auditives.
b) Utiliser la poignée supplémentaire livrée avec
l'appareil. Lapertedecontrôlepeutentraînerdes
blessures.
c) Tenir l’appareil par les surfaces isolées des poi-
gnées lors des travaux pendant lesquels l'outil
utilisé risque de toucher des câbles électriques
cachés. Le contact avec un câble sous tension risque
de mettre les parties métalliques de l’appareil sous
tension et de provoquer une décharge électrique.
5.3 Consignes de sécurité supplémentaires
5.3.1 Sécurité des personnes
a) Lors des travaux pendant lesquels la vis risque
de toucher des câbles électriques cachés, tenir
l’appareil uniquement par les surfaces isolées des
poignées. Le contact de la vis avec un câble conduc-
teur risque aussi de mettre les parties métalliques de
l’appareil sous tension et de provoquer une décharge
électrique.
b) Veiller à ce que les poignées soient toujours
sèches, propres et exemptes de traces de graisse
et d'huile.
c) Faire régulièrement des pauses et des exercices
de relaxation et de massage des doigts pour fa-
voriser l'irrigation sanguine dans les doigts.
d) Éviter de toucher des pièces en rotation. Brancher
l'appareil uniquement dans l'espace de travail. Le
fait de toucher des pièces en rotation, en particulier
des outils en rotation, risque d'entraîner des bles-
sures.
e) Activer le blocage (inverseur D/G sur la position
médiane) pour le stockage et le transport de l'ap-
pareil.
f) Avertir les enfants et veiller à ce qu'ils ne jouent
pas avec l'appareil.
g) L'appareil n'est pas destiné à être utilisé par des
enfantsoudespersonnesaffaibliessansenca-
drement.
