2 Safety
2.1 Additional safety instructions
WARNING! Study all safety instructions and other instructions, images and technical data with
which this power tool is provided. Failure to observe the instructions below can result in electric shock,
fire and/or serious injury.
Keep all safety precautions and instructions for future reference.
The term “power tool” used in the safety precautions refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Safety at the workplace
▶Keep your work area clean and well lit. Cluttered or dark work areas invite accidents.
▶Do not operate the power tool in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
▶Keep bystanders, children and visitors away while operating a power tool. Distractions can cause
you to lose control of the tool.
Personal safety
▶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 the power tool may result in serious personal injury.
▶Wear your personal protective equipment and always wear protective glasses. Depending on the
purpose for which the power tool is to be used, wearing safety equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection will reduce the risk of injury.
▶Avoid accidental starting. Check that the power tool is switched off before you connect it to the
power supply and/or the battery and before picking it up or carrying it. Carrying power tools with
your finger on the switch or plugging in power tools that are already switched on invites accidents.
▶Avoid unaccustomed body positions. Maintain proper footing and balance at all times. This will
allow you to control the power tool better, even in unexpected situations.

*2328838* 2328838 English 3
▶Wear suitable work clothes. Do not wear jewelry or loose clothing. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be snagged by moving parts.

even if you are familiar with the power tool after using it many times. Caress handling could cause
serious injury within fractions of a second.
Using and handling the power tool
▶Do not overload the tool. Use the correct power tool for your application. The correct power tool
will do the job better and more safely within the performance range for which it is designed.
▶Do not use a power tool if it has a faulty On/Off switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
▶Disconnect the plug from the power outlet and/or remove a removable battery before making any
adjustments, changing accessories, or storing the tool. This precaution reduces the risk of the power
tool starting accidentally.
▶Store power tools out of reach of children when not in use. Do not allow persons who are not
familiar with the tool and these instructions to operate it. Power tools are dangerous in the hands of
inexperienced persons.
▶Maintain power tools and accessories carefully. Check that moving parts operate satisfactorily
and do not jam, and whether any parts are broken or so damaged that the correct operation of the
power tool is adversely affected. If parts are damaged, have the parts repaired before using of the
tool. Many accidents are caused by poorly maintained power tools.
▶Use power tools, accessories, insert tools, etc. only as described in this manual. Take the working
conditions and the work to be performed into account. Use of the power tool for operations different
from those intended could result in a hazardous situation.
▶Keep grips and gripping surfaces dry, clean and free from oil and grease. Slippery grips and gripping
surfaces do not allow the power tool to be safely operated and controlled in unforeseen situations.
Using and handling the cordless power tool
▶Recharge the batteries only with the chargers specified by the manufacturer. A charger that is
suitable for a certain type of battery may present a risk of fire when used with other types of battery.
▶Use only the specified batteries in power tools. Use of any other batteries may create a risk of injury
and fire.
▶When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws and other
small metal objects that could cause bridging between the terminals. A short circuit between the
battery terminals may cause burns or a fire.
▶Liquid may leak from the battery if used incorrectly. Avoid contact with the liquid. If contact
accidentally occurs, flush with water. If the liquid contacts the eyes, also seek medical attention.
Liquid escaping from the battery can cause skin irritation or burns.
▶Do not use damaged or modified batteries. Damaged or modified batteries may behave unpredictably

AVERTISSEMENT ! Lire toutes les consignes de sécurité, instructions, illustrations et caractéris-
tiques techniques, qui accompagnent cet outil électroportatif. Tout manquement à l'observation des
instructions suivantes risque de provoquer une électrocution, un incendie et/ou de graves blessures.
Les consignes de sécurité et instructions doivent être intégralement 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 d'alimentation) et à des outils électriques sur accu (sans câble
d'alimentation).
Sécurité sur le lieu de travail
▶Conserver la zone de travail propre et bien éclairée. Un lieu de travail en désordre ou mal éclairé
augmente le risque d'accidents.
▶Ne pas faire fonctionner les outils électriques en atmosphère explosive et où se trouvent des
liquides, des gaz ou poussières inflammables. Les outils électriques produisent des étincelles qui
peuvent enflammer les poussières ou les vapeurs.
▶Maintenir les enfants et les personnes présentes à l'écart pendant l'utilisation de l'outil électro-
portatif. En cas d'inattention il y a risque de perdre le contrôle de l'appareil.
Sécurité des personnes
▶Rester vigilant, surveiller ce que l'on fait. Faire preuve de bon sens en utilisant l'outil électroportatif.
Ne pas utiliser l'outil électroportatif en étant fatigué ou sous l'emprise de l'alcool, de drogues ou
de médicaments. Un moment d'inattention lors de l'utilisation de l'outil électroportatif peut entraîner
des blessures graves.
▶Utiliser un équipement de sécurité et toujours porter une protection pour les yeux. Les équipements
de protection personnels tels que masque antipoussière, chaussures de sécurité antidérapantes, casque
de protection ou protection acoustique suivant l'utilisation de l'outil électroportatif, réduisent le risque de
blessures des personnes.

▶Éviter une mise en service par mégarde. S'assurer que l'outil électroportatif est arrêté avant de le
brancher à la source de courant et/ou à l'accu, de le prendre ou de le porter. Le fait de porter l'outil
électroportatif avec le doigt sur l'interrupteur ou de brancher l'appareil sur la source de courant lorsque
l'interrupteur est en position de fonctionnement peut entraîner des accidents.
▶Adopter une bonne posture. Veiller à toujours garder une position stable et équilibrée. Cela permet
un meilleur contrôle de l'outil électroportatif dans des situations inattendues.
▶S'habiller de manière adaptée. Ne pas porter de vêtements amples ni de bijoux. Garder les
cheveux, les vêtements et les gants à distance des parties en mouvement. Des vêtements amples,
des bijoux ou des cheveux longs peuvent être happés par des parties en mouvement.
▶Ne pas sous-estimer les mesures de sécurité à prendre et ne pas ignorer sciemment les règles
de sécurité applicables aux outils électriques, même si l'on est utilisateur chevronné après de
fréquentes utilisations de l'outil électroportatif. Un manque d'attention peut conduire à de graves
blessures en quelques fractions de seconde.
Utilisation et maniement de l'outil électroportatif
▶Ne pas forcer l'appareil. Utiliser l'outil électroportatif adapté au travail à effectuer. Un outil
électroportatif approprié réalisera mieux le travail et de manière plus sûre au régime pour lequel il a été
conçu.
▶Ne pas utiliser d'outil électroportatif dont l'interrupteur est défectueux. Tout outil électroportatif qui
ne peut plus être mis en ou hors fonctionnement est dangereux et doit être réparé.
▶Débrancher la fiche de la prise de courant et/ou l'accu amovible avant d'effectuer des réglages sur
l'appareil, de changer les accessoires, ou de ranger l'appareil. Cette mesure de précaution empêche
une mise en fonctionnement par mégarde de l'outil électroportatif.
▶Conserver les outils électroportatifs non utilisés hors de portée des enfants. Ne permettre
l'utilisation de l'appareil à aucune personne qui ne soit pas familiarisée avec celui-ci ou qui n'a
pas lu ces instructions. Les outils électroportatifs sont dangereux lorsqu'ils sont entre les mains de
personnes non initiées.
▶Prendre soin des outils électroportatifs et des accessoires. Vérifier que les parties en mouvement
fonctionnent correctement et qu'elles ne sont pas coincées, et contrôler si des parties sont
cassées ou endommagées 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.
▶L'outil électroportatif, les accessoires, les outils amovibles, etc. doivent être utilisés conformément
à ces instructions. Tenir également compte des conditions de travail et du travail à réaliser.
L'utilisation des outils électroportatifs à d'autres fins que celles prévues peut entraîner des situations
dangereuses.
▶Veiller à ce que les poignées et surfaces de préhension soient toujours être sèches, propres et
exemptes de traces de graisse ou d'huile. Avec des poignées et surfaces de préhension glissantes, la
sécurité et le contrôle de l'outil électroportatif ne peuvent être assurés dans des situations inopinées.
Utilisation et maniement de l'outil sur accu
▶Ne charger les accus que dans des chargeurs recommandés par le fabricant. Si un chargeur
approprié à un type spécifique d'accus est utilisé avec des accus non recommandés pour celui-ci, il y a
risque d'incendie.
▶Dans les outils électroportatifs, utiliser uniquement les accus spécialement prévus pour ceux-ci.
L'utilisation de tout autre accu peut entraîner des blessures et des risques d'incendie.
▶Tenir l'accu 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.
▶En cas d'utilisation abusive, du liquide peut sortir de l'accu. Éviter tout contact avec ce liquide. En
cas de contact par mégarde, rincer soigneusement avec de l'eau. Au cas où le liquide rentrerait
dans les yeux, consulter en plus un médecin. Le liquide qui sort de l'accu peut entraîner des irritations
de la peau ou causer des brûlures.
▶Ne pas utiliser d'accu endommagé ou modifié. Des accus endommagés ou modifiés peuvent avoir
un comportement imprévisible et provoquer un incendie, une explosion ou engendrer un risque de
blessures.
▶Ne jamais exposer l'accu au feu ou à des températures trop élevées. Le feu ou des températures
supérieures à 130 °C (265 °F) peuvent provoquer une explosion.
▶Suivre toutes les instructions de charge et ne jamais charger l'accu ou l'outil sur accu hors de la
plage de températures spécifiée dans le manuel d'utilisation. Une charge inappropriée ou hors de la
plage de températures spécifiée risque d'endommager l'accu et accroître le risque d'incendie.
