GENERAL SAFETY RULES
WARNING! Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.
SAVE THESE INSTRUCTIONS.
Work area safety
1. Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
4. 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.
5. 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.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. 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.
Personal Safety
9. 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.
10. Use safety equipment. Always wear eye
protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.
12. 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.
13. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,

3
jewellery or long hair can be caught in moving
parts.
15. If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly used.
Use of these devices can reduce dust-related
hazards.
Power tool use and care
16. 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.
17. 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.
18. 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.
19. 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.
20. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, 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.
Battery tool use and care
23. Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack
into power tools that have the switch on invites
accidents.
24. 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.
25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
26. 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.
27. 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.
SERVICE
28. 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.
29. Follow instruction for lubricating and
changing accessories.
30. Keep handles dry, clean and free from oil and
grease.

NOTE:
• Hold the tool pointed straight at the bolt or nut.
• Excessive fastening torque may damage the
bolt/nut or socket. Before starting your job, always
perform a test operation to determine the proper
fastening time for your bolt or nut.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery
cartridge.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Socket
• Failure to use the correct size socket will
cause a reduction in the fastening torque.
• A worn socket (wear on the hex end or square
end) will cause a reduction in the fastening
torque.
3. Bolt
• Even though the torque coefficient and the
class of bolt are the same, the proper
fastening torque will differ according to the
diameter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class of

7
bolt and the bolt length.
4. The use of the universal joint or the extension bar
somewhat reduces the fastening force of the
impact wrench. Compensate by fastening for a
longer period of time.
5. The manner of holding the tool or the material of
driving position to be fastened will affect the
torque.
6. Operating the tool at low speed will cause a
reduction in the fastening torque.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.

Règles de sécurité générales
AVERTISSEMENT! Veuillez lire l'ensemble des
présentes instructions. Il y a risque de choc électrique,
d'incendie et/ou de blessure grave si toutes les
instructions énumérées ci-dessous ne sont pas
respectées. Le terme ≪outil électrique≫qui figure sur
tous les avertissements énumérés ci-dessous fait
référence à un outil électrique branché sur une prise de
courant (par un cordon d'alimentation) ou alimenté par
batterie (sans fil).
CONSERVEZ CE MODE
D'EMPLOI.
Sécurité de la zone de travail
1. Maintenez la zone de travail propre et bien
éclairée. Les zones de travail encombrées et
sombres ouvrent grande la porte aux accidents.
2. N'utilisez pas les outils électriques dans les
atmosphères explosives, par exemple en
présence de liquides, gaz ou poussières
inflammables. Les outils électriques produisent
des étincelles au contact desquelles la poussière
ou les vapeurs peuvent s'enflammer.
3. Assurez-vous qu'aucun enfant ou curieux ne
s'approche pendant que vous utilisez un outil
électrique. Vous risquez de perdre la maîtrise de
l'outil si votre attention est détournée.
Sécurité en matière d'électricité
4. Les fiches d'outil électrique sont conçues
pour s'adapter parfaitement aux prises de
courant. Ne modifiez jamais la fiche de
quelque façon que ce soit. N'utilisez aucun
adaptateur de fiche sur les outils électriques
avec mise à la terre. En ne modifiant pas les
fiches et en les insérant dans des prises de
courant pour lesquelles elles ont été conçues
vous réduirez les risques de choc électrique.
5. Évitez tout contact corporel avec les surfaces
mises à la terre, telles que les tuyaux,
radiateurs, cuisinières et réfrigérateurs. Le
risque de choc électrique est plus élevé si votre
corps se trouve mis à la terre.
6. N'exposez pas les outils électriques à la pluie
ou à l'eau. La présence d'eau dans un outil
électrique augmente le risque de choc électrique.
7. Ne maltraitez pas le cordon. N'utilisez jamais
le cordon pour transporter, tirer ou débrancher
l'outil électrique. Maintenez le cordon à l'écart
des sources de chaleur, de l'huile, des objets à
bords tranchants et des pièces en mouvement.
Le risque de choc électrique est plus élevé
lorsque les cordons sont endommagés ou
enchevêtrés.
8. Lorsque vous utilisez un outil électrique à
l'extérieur, utilisez un cordon prolongateur
prévu à cette fin. Les risques de choc électrique
sont moindres lorsqu'un cordon conçu pour
l'extérieur est utilisé.
Sécurité personnelle
9. Restez alerte, attentif à vos mouvements et
faites preuve de bon sens lorsque vous
utilisez un outil électrique. Évitez d'utiliser un
outil électrique si vous êtes fatigué ou si vous
avez pris une drogue, de l'alcool ou un
médicament. Un moment d'inattention pendant
l'utilisation d'un outil électrique peut entraîner une

10
grave blessure.
10. Utilisez des dispositifs de sécurité. Portez
toujours un protecteur pour la vue. Les risques
de blessure seront moins élevés si vous utilisez
des dispositifs de sécurité tels qu'un masque
antipoussières, des chaussures à semelle
antidérapante, une coiffure résistante ou une
protection d'oreilles.
11. Prévenez tout démarrage accidentel.
Assurez-vous que l'interrupteur est en
position d'arrêt avant de brancher l'outil. Vous
ouvrez la porte aux accidents si vous transportez
les outils électriques avec le doigt sur
l'interrupteur ou les branchez alors que
l'interrupteur est en position de marche.
12. Retirez toute clé de réglage ou de serrage
avant de mettre l'outil sous tension. Toute clé
laissée en place sur une pièce rotative de l'outil
électrique peut entraîner une blessure.
13. Maintenez une bonne position. Assurez-vous
d'une bonne prise au sol et d'une bonne
position d'équilibre en tout temps. Cela vous
permettra d'avoir une meilleure maîtrise de l'outil
dans les situations imprévues.
14. Portez des vêtements adéquats. Ne portez ni
vêtements amples ni bijoux. Vous devez
maintenir cheveux, vêtements et gants à
l'écart des pièces en mouvement. Les pièces
en mouvement peuvent happer les vêtements
amples, les bijoux et les cheveux longs.
15. Si des accessoires sont fournis pour
raccorder un appareil d'aspiration et de
collecte de la poussière, assurez-vous qu'ils
sont correctement raccordés et qu'ils sont
utilisés de manière adéquate. L'utilisation de
tels accessoires permet de réduire les risques liés
à la présence de poussière dans l'air.
Utilisation et entretien des outils électriques
16. Ne forcez pas l'outil électrique. Utilisez l'outil
électrique adéquat suivant le type de travail à
effectuer. Si vous utilisez l'outil électrique
adéquat et respectez le régime pour lequel il a été
conçu, il effectuera un travail de meilleure qualité
et de façon plus sécuritaire.
17. N'utilisez pas l'outil électrique s'il n'est pas
possible de mettre sa gâchette en position de
marche et d'arrêt. Un outil électrique dont
l'interrupteur est défectueux représente un danger
et doit être réparé.
18. Débranchez la fiche de la source
d'alimentation et/ou retirez le bloc-piles de
l'outil électrique avant d'effectuer tout réglage,
de changer un accessoire ou de ranger l'outil
électrique. De telles mesures préventives
réduisent les risques de démarrage accidentel de
l'outil électrique.
19. Après l'utilisation d'un outil électrique,
rangez-le hors de portée des enfants et ne
laissez aucune personne l'utiliser si elle n'est
pas familiarisée avec l'outil électrique ou les
présentes instructions d'utilisation. Les outils
électriques représentent un danger entre les
mains de personnes qui n'en connaissent pas le
mode d'utilisation.
20. Veillez à l'entretien des outils électriques.
Assurez-vous que les pièces mobiles ne sont
pas désalignées ou coincées, qu'aucune pièce
n'est cassée et que l'outil électrique n'a subi
aucun dommage affectant son bon
fonctionnement. Le cas échéant, faites réparer
l'outil électrique avant de l'utiliser. De
nombreux accidents sont causés par des outils
électriques mal entretenus.
21. Maintenez les outils tranchants bien aiguisés
et propres. Un outil tranchant dont l'entretien est
effectué correctement et dont les bords sont bien
aiguisés risquera moins de se coincer et sera plus
facile à maîtriser.
22. Utilisez l'outil électrique, ses accessoires, ses
embouts, etc., en respectant les présentes
instructions et de la façon prévue pour ce type
particulier d'outil électrique, en tenant compte
des conditions de travail et du type de travail à
effectuer. L'utilisation d'un outil électrique à des
fins autres que celles prévues peut entraîner une
situation dangereuse.
Utilisation et entretien des outils alimentés par
batterie
23. Avant d'insérer le bloc-piles, assurez-vos que
l'interrupteur est en position d'arrêt. Vous
ouvrez la porte aux accidents si vous insérez le
bloc-piles dans un outil électrique dont
l'interrupteur est en position de marche.
24. Pour recharger, utilisez uniquement le
chargeur spécifié par le fabricant. L'utilisation
d'un chargeur conçu pour un type donné de
bloc-piles comporte un risque d'incendie lorsqu'il
est utilisé avec un autre type de bloc-piles.
25. N'utilisez un outil électrique qu'avec le
bloc-piles conçu spécifiquement pour cet outil.
Il y a risque de blessure ou d'incendie si un autre
bloc-piles est utilisé.
26. Lorsque vous n'utilisez pas le bloc-piles,
rangez-le à l'écart des objets métalliques tels
que trombones, pièces de monnaie, clés,
clous, vis ou autres petits objets métalliques
qui risquent d'établir une connexion entre les
bornes. La mise en court-circuit des bornes de
batterie peut causer des brûlures ou un incendie.
27. Dans des conditions d'utilisation inadéquates
