2.1 General safety precautions for power tools
WARNING! Read all safety precautions and other instructions. Failure to observe the safety
precautions and other instructions may result in electric shock, fire and/or serious injury.
Keep all safety precautions and instructions for future reference.
Working area safety
▶Keep your working area clean and well lit. Cluttered or dark working areas can cause 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 the power tool. Distractions may cause
you to lose control of the tool.
Electrical safety
▶Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶Do not allow your body to come into contact with grounded surfaces such as pipes, radiators,
ovens and refrigerators. There is an increased risk of electric shock if your body is grounded.
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.
▶Adopt the correct posture when working. Maintain proper footing and balance at all times. This
will allow you to control the power tool better, even in unexpected situations.
▶Wear your personal protective equipment and always wear protective glasses. Depending on the
type of power tool you are using and its purpose, wearing safety equipment such as a dust mask,
slip-resistant safety shoes, a hard hat or hearing protection will reduce the risk of injury.
▶Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair may be caught in moving parts.
▶Avoid starting the tool accidentally. Make sure that the power tool is switched off before connecting
it to 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 may cause accidents.
▶Remove accessory tools or wrenches before switching the power tool on. An accessory tool or a
wrench left attached to a rotating part of the power tool may cause personal injury.
▶If devices are provided for connecting dust extraction and collection equipment, make sure these
are connected and used correctly. The use of a dust extraction system can reduce dust-related
hazards.
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.
▶Remove the battery from the power tool 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 or these instructions to operate it. Power tools are dangerous in the hands of
untrained users.

▶Maintain power tools properly. Check that moving parts are in correct working order and do not
jam, and check whether any parts are broken or so damaged that correct operation of the power
tool cannot be guaranteed. If any parts are damaged, have these parts repaired before using the
tool. Many accidents are caused by poorly maintained power tools.
▶Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to jam and are easier to control.
Using and handling the cordless power tool
▶Use only the specified batteries in the power tools. Use of any other batteries may present a risk of
injury and fire.
▶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.
▶When the battery is not in use, keep it away from other metal objects such as paper clips, coins,
keys, nails, screws, or 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 this liquid. Liquid leaking
from the battery may cause skin irritation or burns. If contact accidentally occurs, rinse with water. Seek
medical attention if the liquid comes into contact with the eyes.
2.2 Safety instructions for all saws
Cutting procedures
▶DANGER: Keep hands away from cutting area and the blade. Keep your second hand on
auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
▶Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
▶Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
▶Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable
platform. It is important to support the work properly to minimize body exposure, blade binding, or loss
of control.
▶Hold the power tool by insulated gripping surfaces only, when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts
of the power tool "live" and could give the operator an electric shock.
▶When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
▶Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
▶Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and safety of operation.
Kickback causes and related warnings
• kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the operator;
• when the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the operator;
• if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig
into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the
operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided
by taking proper precautions as given below.
▶Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces.
Position your body to either side of the blade, but not in line with the blade. Kickback could cause
the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions
are taken.
▶When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the
saw motionless in the material until the blade comes to a complete stop. Never attempt to remove
the saw from the work or pull the saw backward while the blade is in motion or kickback may
occur. Investigate and take corrective actions to eliminate the cause of blade binding.
▶When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the
workpiece as the saw is restarted.
Printed: 01.09.2017 | Doc-Nr: PUB / 5292940 / 000 / 00Printed: 01.09.2017 | Doc-Nr: PUB / 5292940 / 000 / 01

4
▶Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag
under their own weight. Supports must be placed under the panel on both sides, near the line of cut and
near the edge of the panel.
▶Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kickback.
▶Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause binding and kickback.
▶Use extra caution when sawing into existing walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
Lower guard function
▶Check lower guard for proper closing before each use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp or tie the lower guard into the open position. If
saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle
and make sure it moves freely and does not touch the blade or any other part, in all angles and depths
of cut.
▶Check the operation of the lower guard spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
▶Lower guard may be retracted manually only for special cuts such as "plunge cuts" and "compound
cuts". Raise lower guard by retracting handle and as soon as blade enters the material, the lower
guard must be released. For all other sawing, the lower guard should operate automatically.
▶Always observe that the lower guard is covering the blade before placing saw down on bench or
floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade to stop after switch is released.
2.3 Additional safety instructions
Personal safety
▶Modification of the power tool is not permitted.
▶Wear ear protectors. Exposure to noise can cause hearing loss.
▶Operate the tool only together with the safety devices that belong to it.
▶Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶The power tool is not intended for use by inexperienced persons who have received no special
training.
▶Keep the power tool out of reach of children.
▶Do not switch the product on before it is at the workplace.
▶Remove the battery before storing or transporting the power tool.
▶Do not work overhead with the product.
▶Do not attempt to brake the product by applying lateral pressure to the saw blade.
▶Do not touch the clamping flange or the clamping screw while the power tool is running.
▶Never press the drive spindle lock button while the saw blade is rotating.
▶Never direct the power tool toward persons.
▶Adjust the pressure applied to the saw blade and the material being cut so that the blade does not
stall, possibly causing kickback.
▶Metal chips / cuttings are sharp and may cause injury. Keep your clothing closed so that no metal
chips or cuttings can find their way into your gloves, footwear or any other part of your clothing.
▶Pay attention to where the metal cuttings are flying. The cuttings are hot and could cause a fire or
injuries such as burns or cuts.
▶Avoid overheating the tips of the saw blade teeth.
▶Observe the national health and safety requirements.
▶To reduce the risk of injury, use only genuine Hilti accessories and accessory tools.
▶Dust from materials, such as paint containing lead, some wood species, concrete / masonry / stone
containing silica, and minerals as well as metal, may be harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory or other diseases to the operator or bystanders. Certain
kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with
additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be
handled only by specialists. Use a dust removal system whenever possible. To achieve a high level
of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
Printed: 01.09.2017 | Doc-Nr: PUB / 5292940 / 000 / 00Printed: 01.09.2017 | Doc-Nr: PUB / 5292940 / 000 / 01

for the type of dust generated. Ensure that the workplace is well ventilated. Follow national
requirements for the materials you want to work with.
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 live, for example, when an electric cable is damaged accidentally. This presents a serious
risk of electric shock.
Careful handling and use of batteries
▶Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶Do not expose batteries to high temperatures and keep them away from fire. There is a risk of
explosion.
▶Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over
80°C (176°F). This presents a risk of fire, explosion or injury through contact with caustic substances.
▶Never continue to use or attempt to charge damaged batteries, e.g. batteries with cracks, broken
parts, bent or pushed-in / pulled-out contacts).
▶Do not use the battery as a power source for other unspecified power tools or appliances.
▶If the battery is too hot to hold, it may be defective.In this case, place the power tool in a non-
flammable location, well away from flammable materials, where it can be kept under observation
and allowed to cool down. Contact HiltiService after the battery has cooled down.

2 Sécurité
2.1 Indications générales de sécurité pour les outils électriques
AVERTISSEMENT ! Lire et comprendre toutes les consignes de sécurité et instructions. Tout
manquement à l'observation des consignes de sécurité et instructions 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.
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 électrique.
En cas d'inattention il y a risque de perdre le contrôle de l'appareil.
Sécurité relative au système électrique
▶Ne pas exposer les outils électriques à la pluie ou à l'humidité. La pénétration d'eau à l'intérieur d'un
outil électrique augmentera le risque d'un choc électrique.
▶Éviter les contacts du corps avec des surfaces mises à la terre tels que tuyaux, radiateurs,
cuisinières et refrigérateurs. Il y a un risque élevé de choc électrique au cas où votre corps serait relié
à la terre.
Sécurité des personnes
▶Rester vigilant, surveiller ce que l'on fait. Faire preuve de bon sens en utilisant l'outil électrique.
Ne pas utiliser l'outil électrique 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 électrique peut entraîner des
blessures graves.
▶Adopter une bonne posture. Veiller à toujours garder une position stable et équilibrée. Cela permet
un meilleur contrôle de l'outil électrique dans des situations inattendues.
▶Utiliser un équipement de protection individuelle 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 électrique,
réduiront le risque de blessures des personnes.
▶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.
▶Éviter une mise en service par mégarde. S'assurer que l'outil électrique est arrêté avant de le
brancher à l'accu, de le prendre ou de le porter. Le fait de porter l'outil électrique 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 électrique en fonctionnement. Une
clé ou un outil se trouvant sur une partie en rotation peut causer des blessures.
▶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.
Utilisation et maniement de l'outil électrique
▶Ne pas forcer l'appareil. Utiliser l'outil électrique adapté au travail à effectuer. Un outil électrique
approprié réalisera mieux le travail et de manière plus sûre au régime pour lequel il a été conçu.

▶Ne pas utiliser d'outil électrique dont l'interrupteur est défectueux. Tout outil électrique qui ne peut
plus être mis en ou hors fonctionnement est dangereux et doit être réparé.
▶Retirer le bloc-accu, 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 électrique.
▶Conserver les outils électriques non utilisés hors de portée des enfants. Ne pas permettre
l'utilisation de l'appareil à des personnes qui ne se sont pas familiarisées avec celui-ci ou qui
n'ont pas lu ces instructions. Les outils électriques sont dangereux lorsqu'ils sont entre les mains de
personnes non initiées.
▶Prendre soin des outils électriques. Vérifier que les parties en mouvement fonctionnent correcte-
ment 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 électrique s'en trouve entravé. Faire réparer les
parties endommagées avant d'utiliser l'appareil. De nombreux accidents sont dus à des outils
électriques mal entretenus.
▶Garder les outils de coupe affûtés et propres. Des outils destinés à couper correctement entretenus
avec des bords tranchants bien aiguisés se coincent moins souvent et peuvent être guidés plus
facilement.
Utilisation et maniement de l'outil sur accu
▶Dans les outils électriques, utiliser uniquement les accus spécialement prévus pour ceux-ci.
L'utilisation de tout autre accu peut entraîner des blessures et des risques d'incendie.
▶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.
▶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.
Le liquide qui sort de l'accu peut entraîner des irritations de la peau ou causer des brûlures. En cas de
contact par mégarde, rincer soigneusement avec de l’eau. En cas de contact de fluide avec les yeux,
solliciter l'aide d'un personnel médical qualifié.
2.2 Consignes de sécurité pour toutes les scies
Procédé de sciage
▶DANGER : Bien garder les mains à distance de la zone de sciage et de la lame de scie. Tenir la
poignée supplémentaire ou le carter du moteur de l’autre main. Si la scie est tenue des deux mains,
celles-ci ne risquent pas d'être blessées par la lame de scie.
▶Ne pas passer les mains sous la pièce travaillée. Sous la pièce travaillée, le capot de protection ne
peut pas protéger l'utilisateur contre la lame de scie.
▶Adapter la profondeur de coupe à l'épaisseur de la pièce travaillée. Moins d’une dent complète
devrait apparaître sous la pièce.
▶Ne jamais tenir la pièce à scier avec la main ou sur la jambe. Fixer la pièce sur un support stable.
Il est important de bien fixer la pièce, afin de réduire au minimum les dangers de contact physique, de
coincement de la lame de scie ou de perte de contrôle.
▶Saisir l’outil électroportatif uniquement par les surfaces isolées des poignées lors des travaux
pendant lesquels l'appareil utilisé risque de toucher des câbles électriques cachés. Le contact
avec un câble sous tension met les parties métalliques de l'outil électroportatif sous tension et provoque
une décharge électrique.
▶Toujours utiliser une butée ou un guidage droit de bords pour des coupes longitudinales. Ceci
améliore la précision de coupe et réduit le danger de voir la lame de scie se coincer.
▶Toujours utiliser des lames de scie de la bonne taille et dont l'alésage de fixation est de forme
appropriée (par ex. en étoile ou rond). Les lames de scie qui ne conviennent pas aux pièces
d'assemblage de la scie sont comme voilées et entraînent une perte de contrôle.
▶Ne jamais utiliser de rondelles ou de vis endommagées ou qui ne conviennent pas pour la lame de
scie. Les rondelles et vis pour la lame de scie ont spécialement été conçues pour cette scie, pour des
performances et une sécurité de fonctionnement optimales.
Contrecoup – Causes et consignes de sécurité correspondantes
• un contrecoup est une réaction soudaine d'une lame de scie restée accrochée, coincée ou mal orientée,
qui provoque le soulèvement incontrôlé de la scie et sa sortie de la pièce travaillée en direction de
l'utilisateur ;
