GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings, instructions, illustrations and specications
provided with this power tool. Failure to follow all instructions listed below may
result in electric shock, re 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
ammable 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. Unmodied 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.
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 ground fault circuit
interrupter (GFCI) protected supply. Use of a
GFCI 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 inuence 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 nger on the
switch or energizing 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 jewelry. Keep your hair and clothing away
from moving parts. Loose clothes, jewelry 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.

-4-
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 specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
Use power tools only with specically
designated battery packs. Use of any other
battery packs may create a risk of injury and
re.
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 re.
Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, ush 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 modied. Damaged or modied
batteries may exhibit unpredictable behavior
resulting in re, explosion or risk of injury.
Do not expose a battery pack or tool to re
or excessive temperature. Exposure to re or
temperature above 265 °F (130 °C) may cause
explosion.
Follow all charging instructions and do
not charge the battery pack or tool outside
the temperature range specied in the
instructions. Charging improperly or at
temperatures outside the specied range may
damage the battery and increase the risk of re.
Service
Have your power tool serviced by a
qualied 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.

products can expose you to wood dust, a
substance known to the State of California to
cause cancer. Avoid inhaling wood dust or use
a dust mask or other safeguards for personal
protection. For more information go to
www.P65Warnings.ca.gov/wood.
• Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contains chemicals known to the
State of California to cause cancer, birth
defects or other reproductive harm. Some
examples of these chemicals are:
– Lead from lead-based paints.
– Crystalline silica from bricks, cement, and
other masonry products.
– Arsenic and chromium from chemically-treated
lumber.
• Your risk from these exposures varies,
depending upon how often you do this type
of work. To reduce your exposure to these
chemicals:
– Work in a well-ventilated area.
– Work with approved safety equipment, such
as dust masks that are specially designed to
lter out microscopic particles.
– Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing
and wash exposed areas with soap and water.

AVERTISSEMENTS GÉNÉRAUX RELATIFS À LA SÉCURITÉ POUR
LES OUTILS ÉLECTRIQUES
AVERTISSEMENT Lisez tous les avertissements relatifs à la sécurité, les
instructions, les illustrations et les spécications fournies avec
cet outil électrique. Le non-respect de toutes les instructions gurant ci-après pourrait causer un
choc électrique, un incendie et/ou des blessures graves.
CONSERVEZ TOUS LES AVERTISSEMENTS ET TOUTES LES INSTRUCTIONS
POUR RÉFÉRENCE FUTURE.
Le terme « outil électrique » dans les avertissements fait référence à votre outil électrique à cordon
électrique branché dans une prise secteur ou à votre outil électrique à piles (sans l).
Sécurité de la zone de travail
Gardez votre zone de travail propre et bien
éclairée. Des zones encombrées ou sombres
sont propices aux accidents.
N’utilisez pas des outils électriques dans
une atmosphère explosive, par exemple
en présence de liquides, de gaz ou de
poussières inammables. Les outils
électriques produisent des étincelles qui
risquent de mettre feu aux poussières ou aux
émanations de fumée.
Gardez les enfants et autres personnes
présentes à une distance sufsante lorsque
vous utilisez un outil électrique. Des
distractions risqueraient de vous faire perdre le
contrôle.
Sécurité électrique
La che de l’outil électrique doit
correspondre à la prise de courant. Ne
modiez jamais une che de quelque façon
que ce soit. N’utilisez pas d’adaptateurs
de ches avec des outils électriques mis
à la terre/à la masse. L’emploi de ches non
modiées et de prises de courant correspondant
naturellement aux ches réduira le risque de
choc électrique.
Évitez tout contact de votre corps avec des
surfaces mises à la terre ou à la masse telles
que des surfaces de tuyaux, de radiateurs,
de cuisinières et de réfrigérateurs. Il existe un
risque accru de choc électrique si votre corps
est en contact avec la terre ou la masse.
N’exposez pas d’outils électriques à la
pluie ou à un environnement humide. La
pénétration d’eau dans un outil électrique
augmentera le risque de choc électrique.
N’utilisez pas le cordon de façon abusive.
N’utilisez pas le cordon pour porter, tirer
ou débrancher l’outil électrique. Tenez
le cordon à distance de toute source de
chaleur, d’huile, de bords tranchants ou de
pièces mobiles. Des cordons endommagés
ou entortillés augmentent le risque de choc
électrique.
Lorsque vous utilisez un outil électrique à
l’extérieur, employez un cordon de rallonge
approprié pour un emploi à l’extérieur.
L’utilisation d’un cordon approprié pour une
utilisation à l’extérieur réduit le risque de choc
électrique.
S’il est inévitable d’utiliser un outil
électrique dans un environnement humide,
utilisez une alimentation protégée par un
disjoncteur de circuit de fuite à la terre.
L’utilisation d’un tel circuit réduit le risque de
choc électrique.
Sécurité personnelle
Faites preuve de vigilance et de bon sens, et
observez attentivement ce que vous faites
lorsque vous utilisez un outil électrique.
N’utilisez pas un outil électrique si vous êtes
fatigué(e) ou sous l’inuence de drogues,
d’alcool ou de médicaments. Un simple
moment d’inattention pendant que vous utilisez
un outil électrique pourrait causer une blessure
grave.
Utilisez des équipements de protection
personnelle. Portez toujours des
équipements de protection des yeux.
Des équipements de protection tels qu’un
masque de protection contre la poussière, des
chaussures de sécurité antidérapantes, un
casque ou un dispositif de protection de l’ouïe
utilisés en fonction des conditions réduiront le
nombre des blessures.
