2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
▶Keep work area clean and well lit. Cluttered or dark areas invite accidents.
▶Do not operate power tools 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 children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
Electrical safety
▶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. Unmodified plugs and matching outlets will reduce risk of
electric shock.
▶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.

*2321707* 2321707 English 3
▶Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶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 the
risk of electric shock.
▶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.
▶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.
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 power tools may result in serious personal injury.
▶Use personal protective equipment. Always wear eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.
▶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.
▶Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
▶Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
▶Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
▶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.
▶Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe injury within a fraction of a second.
Power tool use and care
▶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.
▶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.
▶Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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.
▶Store idle power tools out of the reach of children 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.
▶Maintain power tools and accessories. 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.
▶Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
▶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
operations different from those intended could result in a hazardous situation.
▶Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Battery tool use and care
▶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.
▶Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
▶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.

4 English 2321707 *2321707*
▶Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
▶Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
▶Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130° C (265 °F) may cause explosion.
▶Follow all charging instructions and do not charge the battery pack or tool outside the temperature
range specified in the instructions. Charging improperly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
Service
▶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.
▶Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
2.2 Additional safety instructions for pressing tools

2 Sécurité
2.1 Indications générales de sécurité pour les appareils électriques
AVERTISSEMENT Lire toutes les consignes de sécurité et 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 fumées.
▶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 relative au système électrique
▶La fiche de secteur de l'outil électroportatif doit être adaptée à la prise de courant. Ne jamais
modifier la fiche de quelque façon que ce soit. Ne pas utiliser d'adaptateurs avec des outils
électriques à branchement de terre. Des fiches non modifiées et des prises de courant adaptées
réduiront le risque de choc électrique.
▶Éviter le contact physique avec des surfaces mises à la terre tels que tuyaux, radiateurs, cuisinières
et réfrigérateurs. Il y a un risque élevé de choc électrique au cas où votre corps serait relié à la terre.
▶Ne pas exposer les outils électroportatifs à la pluie ou à l'humidité. La pénétration d'eau à l'intérieur
d'un outil électroportatif augmentera le risque d'un choc électrique.
▶Ne jamais utiliser le câble de raccordement à d'autres fins que celles prévues, telles que pour
porter, accrocher ou débrancher l'outil électroportatif de la prise de courant. Maintenir le câble
de raccordement à l'écart de la chaleur, des parties grasses, des bords tranchants ou des parties
en mouvement. Des câbles de raccordement endommagés ou emmêlés augmentent le risque de choc
électrique.
▶Si l'outil électroportatif est utilisé à l'extérieur, utiliser uniquement des câbles de rallonge
homologués pour les applications extérieures. L’utilisation d’un câble de rallonge homologué
pour les applications extérieures réduit le risque d’un choc électrique.
▶Si l'utilisation de l'outil électrique dans un environnement humide ne peut pas être évitée, utiliser
un interrupteur de protection contre les courants de court-circuit. L'utilisation d'un tel interrupteur
de protection réduit le risque d'une décharge électrique.
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 protection personnel 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, réduiront le risque de blessures des personnes.

*2321707* 2321707 Français 15
▶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.
▶Retirer tout outil de réglage ou toute clé avant de mettre l'outil électroportatif en fonctionnement.
Une clé ou un outil se trouvant sur une partie en rotation peut causer des blessures.
▶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.
▶Si des dispositifs servant à aspirer ou à recueillir les poussières doivent être utilisés, s'assurer
qu'ils sont effectivement raccordés et correctement utilisés. L'utilisation d'un dispositif d'aspiration
de la poussière peut réduire les risques dus aux poussières.
▶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.
▶Garder les outils de coupe affûtés et propres. Des outils destinés à couper correctement entretenus
avec des arêtes de coupe tranchantes sont moins susceptibles de bloquer et sont plus faciles à contrôler.
▶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.

16 Français 2321707 *2321707*
▶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.
Service
▶L'outil électroportatif doit uniquement être réparé par un personnel qualifié et seulement avec des
pièces de rechange d'origine. Ceci permet d'assurer la sécurité de l'appareil.
▶Ne jamais entretenir d'accus endommagés. Toutes les opérations d'entretien sur des accus doivent
exclusivement être réalisées par le fabricant ou un prestataire de service client agréé.
2.2 Consignes de sécurité supplémentaires spécifiques à la sertisseuse

contrôler si l'accu et l'accessoire monté sont solidement fixés.
▶Ne pas fixer l'éclairage (LED) du produit et ne pas projeter la lumière dans le visage d'autres personnes.
Il y a risque d'éblouissement.
▶Toujours maintenir la sécurité anti-chute et la longe porte-outil propres et sèches.
▶Ne jamais compresser des tubes dans un réseau de gaz sans y avoir été expressément autorisé par le
fournisseur du système pour une utilisation de cet sertisseuse et de raccords spéciaux contrôlés.
▶Procéder ensuite à un contrôle d'étanchéité sur le système de tuyaux comprimé afin d'écarter tout défaut
d'étanchéité (par ex. en raison de mauvaises utilisations).
Sécurité relative au système électrique
▶Avant d'utiliser la sertisseuse, il faut mettre hors tension tous les éléments actifs, c'est-à-dire les éléments
conducteurs de courant qui se trouvent dans l'environnement de travail de l'opérateur. Si ce n'est pas
possible, prendre des mesures de protection appropriées pour travailler à proximité de composants sous
tension électrique.
▶Avant d'entamer le travail, vérifier qu'il n'y a pas de câbles ou gaines électriques, tuyaux de gaz ou d’eau
cachés dans la zone d'intervention. Les parties métalliques externes du produit peuvent provoquer un
choc électrique ou une explosion si vous endommagez une ligne électrique, une conduite de gaz ou une
conduite d'eau.
▶Ne jamais faire de sertissage sur des pièces sous tension. La sertisseuse étant considérée comme non
isolée, il faut par conséquent l'utiliser avec un équipement de protection individuel (gants, chaussures,
vêtements, etc.) apte à protéger l'utilisateur ainsi que toute personne se trouvant à proximité.
Utilisation et emploi soigneux des outils électroportatifs
▶Toutes les 50 opérations environ, mettre l'outil de sertissage hors tension et faire une pause de 15 min
environ pour le laisser refroidir. Toute surchauffe risque d'endommager la sertisseuse.
▶Stocker la sertisseuse dans un endroit sec hors de la portée des enfants et des personnes non autorisées.
▶Hilti recommande de faire réviser l'outil de sertissage après 15 000 opérations de sertissage par le S.A.V.
