General Power Tool Safety Warnings
_WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions 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
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) 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.
c) Keep children and bystanders away while operating a
power tool Distractions can cause you to lose control
2} ELECTRICAL SAFETY
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) 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.
e) When operating apower 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 apowertool in a damp location is unavoidable,
use a ground fault circuff interrupter (GFCI) protected
supply. Use of a GFC/ reduces the risk of electric shock.

3) PERSONAL SAFETY
a) 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.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) 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 energizing power
tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) 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 can be caught in
moving parts.
g) 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.
4} POWER TOOL USE AND CARE
a) 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.
b) 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.
c) 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.
d) 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.
e) Maintain power tools. 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
g) 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.
5) BATFERY TOOL USE AND CARE
a) 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.
b) Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.

c) When battery pack is not in use, keep Haway 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 bums or a fire.
d) 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 bums.
6) SERVICE
a) 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.
Additional Specific Safety Rules for
Reciprocating Saws
•Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
•Use clamps or anotherpractical way to secure and support
the workpiece to a stable platform. Holding the work by
hand or against your body leaves H unstable and may lead
to loss of control.
•Hold saw firmly with both hands for all cutting operations.
During cutting operations, the blade may suddenly bind in the
work and may cause the saw to kickback towards the operator.
•Keep hands away from moving parts. Neverplace your hands
near the cutting area.
•Use extra caution when cutting overhead and pay particular
attention to overhead wires which may be hidden from view.
Anticipate the path of falling branches and debris ahead of time.
•Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause permanent
injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.
_WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOT safety glasses. Also use face or dust mask if cutting operation is
dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
AWARNING: 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 and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to
filter 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. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.

_WARNING: Use of this tool can generate and/or disperse dust,
which may cause serious and permanent respiratory or other injury.
Always useNIOSH/OSHA approved respiratory protection appropriate
for the dust exposure. Direct particles away from face and body.
_WARNING: Always wear proper personal hearing protection
that conforms to ANSI $12.6 ($3.19) during use. Under some
conditions and duration of use, noise from this product may
contribute to hearing loss.
_CAUTION: When not in use, place tool on its side on a stable
surface where it will not cause a tripping or falling hazard.

_WARNING: Fire hazard. Do not store or carry battery so
that metal objects can contact exposed battery terminals.
For example, do not place battery in aprons, pockets, tool boxes,
product kit boxes, drawers, etc., with loose nails, screws, keys, etc.
Transporting batteries can possibly cause fires if the battery
terminals inadvertently come in contact with conductive
materials such as keys, coins, hand tools and the like. The
US Department of Transportation Hazardous Material Regulations
(HMR) actually prohibit transporting batteries in commerce or on
airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS
they are properly protected from short circuits. So when transporting
individual batteries, make sure that thebattery terminals areprotected
and well insulated from materials that could contact them and cause
a short circuit.
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-lon)
• Do not incinerate the battery pack even if it is severely
damaged or is completely worn out. The battery pack can
explode in a fire. Toxic fumes and materials are created when
lithium ion battery packs are burned.
•If battery contents come into contact with the skin,
immediately wash area with mild soap and water. If battery
liquid gets into the eye, rinse water over the open eye for 15
minutes or until irritation ceases. If medical attention is needed,
the battery electrolyte is composed of a mixture of liquid organic
carbonates and lithium salts.
•Contents of opened battery cells may cause respiratory
irritation. Provide fresh air. If symptoms persists, seek medical
attention.
,_J,WARNING: Bum hazard. Battery liquid may be flammable if
exposed to spark or flame.
The RBRC TM Seal
The RBRC TM (Rechargeable Battery Recycling
Corporation) Seal on the nickel cadmium, nickel metal
hydride or lithium ion batteries (or battery packs)
indicate that the costs to recycle these batteries (or
battery packs) at the end of their useful life have already
been paid by DEWALT. In some areas, it is illegal to
place spent nickel cadmium, nickel metal hydride or lithium ion
batteries in the trash or municipal solid waste stream and the RBRC
program provides an environmentally conscious alternative.
RBRCTM, in cooperation with DEWALT and other battery users, has
established programs in the United States and Canada to facilitate
the collection of spent nickel cadmium, nickel metal hydride or lithium
ion batteries. Help protect our environment and conserve natural
resources by returning the spent nickel cadmium, nickel metal
hydride or lithium ion batteries to an authorized DEiWALT service
center or to your local retailer for recycling. You may also contact
your local recycling center for information on where to drop off the
spent battery.

Important Safety Instructions for All
Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety and operating instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
,_,WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock may result.

_CAUTION: Bum hazard. Toreduce the risk of injury, charge only
DEWALT rechargeable batteries. Other types of batteries may burst
causing personal injury and damage.
NOTICE: Under certain conditions, with the charger plugged in to
the power supply, the charger can be shorted by foreign material
Foreign materials of a conductive nature such as, but not limited to,
grinding dust, metal chips, steel wool, aluminum foil, or any buildup of
metallic particles should be kept away from charger cavities. Always
unplug the charger from the power supply when there is no battery
pack in the cavity, Unplug charger before attempting to clean.
•DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual. The charger and
battery pack are specifically designed to work together.
•These chargers are not intended for any uses other than
charging DEWALT rechargeable batteries. Any other uses
may result in risk of fire, electric shock or electrocution.
•Do not expose charger to rain or snow.
•Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure that cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.
•Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in risk of
fire, electric shock, or electrocution.
•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.
•An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord.

Chargers
Your tool uses a DEWALT charger. Be sure to read all safety
instructions before using your charger. Consult the chart on the back
cover of this manual for compatibility of chargers and battery packs.
Charging Procedure (Fig. 1)
1. Plug the charger into an appropriate outlet before inserting battery
pack.
2. Insert the battery pack (J) into the charger, as shown in Figure 1,
making sure the pack is fully seated in charger. The red (charging)
light will blink continuously indicating that the charging process
has started.
FIG. 1
3. The completion of charge will be indicated by the red light
remaining ON continuously. The pack is fully charged and may
be used at this time or left in the charger.
Charge Indicators
Some chargers are designed to detect certain problems that can arise
with battery packs. Problems are indicated by the red light flashing
at a fast rate. If this occurs, re-insert battery pack into the charger. If
the problem persists, try a different battery pack to determine if the
charger is OK. If the new pack charges correctly, then the original
pack is defective and should be returned to a service center or
other collection site for recycling. If the new battery pack elicits the
same trouble indication as the original, have the charger tested at an
authorized service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the
charger detects a battery that is hot, it automatically starts a Hot Pack
Delay, suspending charging until the battery has cooled. After the
battery has cooled, the charger automatically switches to the Pack
Charging mode. This feature ensures maximum battery life. The red
light flashes long, then short while in the Hot/Cold Pack Delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.
WEAK BA'R'ERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty
battery pack. The charger will indicate faulty battery pack by refusing
to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.

Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65 °F
and 75 °F (18-24 °C). DO NOT charge the battery pack in air
temperature below +40 °F (+4.5 °C),or above +105 °F (+40.5 °C).
This is important and will prevent serious damage to the battery
pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other
appliance;
b. Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights;
c. Move charger and battery pack to a location where the
surrounding air temperature is approximately 65 °F-75 °F
(18-24 °C);
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Foreign materials of a conductive nature such as, but not limited
to, grinding dust, metal chips, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug charger before
attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
_WARNING: Shock hazard. Don't allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Never attempt to open the battery pack for any reason.
If the plastic housing of the battery pack breaks or cracks, return to a
service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry away from
direct sunlight and excess heat or cold.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool dry place out of the charger for optimal
results.
NOTE: Battery packs should not be stored completely depleted of
charge. The battery pack will need to be recharged before use.

Cutting (Fig. 9, 10-13)
AWARNING: Always use eye protection. All users and bystanders
must wear eye protection that conforms to ANSI Z87.1.
AWARNING: Exercise extra caution when cutting towards operator.
Always hold saw firmly with both hands while cutting.
Before cutting any type of material, be sure it is firmly anchored or
clamped to prevent slipping. Place blade lightly against work to be
cut, switch on saw motor and allow it to obtain maximum speed
before applying pressure. Whenever possible, the saw shoe must be
held firmly against the material being cut. This will prevent the saw
from jumping or vibrating and minimize blade breakage. Any cuts
which put pressure on the blade such as angle or scroll cuts increase
potential for vibration, kickback, and blade breakage.
AWARNING: Use extra caution when cutting overhead and pay
particular attention to overhead wires which may be hidden from view.
Anticipate the path of falling branches and debris ahead of time.
J_WARNING: Inspect work site for hidden gas pipes, water pipes,
or electrical wires before making blind or plunge cuts. Failure to do
so may result in explosion, property damage, electric shock, and/or
serious personal injury.
FLUSH-TO CUTTING (FIG. 9B, 10)
The compact design of the saw motor
housing and spindle housing permits
extremely close cutting to floors, corners
and other difficult areas. The blade should
be inserted upside-down to assist in flush-
cutting (Fig. 9B, 10).
FIG. 10
POCKET/PLUNGE CUTTING - WOOD
ONLY (FIG. 11)
The initial step in pocket cutting is to
measure the surface area to be cut
and mark clearly with a pencil, chalk or
scriber. Use the appropriate blade for the
application. The blade should be longer
than 3-1/2" (89 mm) and should extend
past the shoe and the thickness of the workpiece during the cut. A 4"
(102 mm) blade is recommended for best performance. Insert blade
into the blade clamp.

surebladeiscompletelythroughmaterialbeforecontinuingwith
pocketcut.
NOTE: In areas where blade visibility is limited, use the edge of the
saw shoe as a guide. Lines for any given cut should be extended
beyond edge of cut to be made.
METAL cu'rI'ING (FIG. 12}
Your saw has different metal cutting capacities depending upon type
of blade used and the metal to be cut. Use a finer blade for ferrous
metals and a coarse blade for non-ferrous materials. In thin gauge
sheet metals it is best to clamp wood to both sides of sheet. This
will ensure a clean cut without excess vibration or tearing of metal.
Always remember not to force cutting blade as this reduces blade life
and causes costly blade breakage.
NOTE: It is generally recommended that when cutting metals you
should spread a thin film of oil or other lubricant along the lineahead
of the saw cut for easier operation and longer blade life.
FIG. 12
HORIZONTAL/VERTICAL SAW MODES (FIG. 13)
The saw can be used in either of the modes shown.
Horizontal Mode: Blade teeth face downward as shown in
Figure 13A.
Vertical Mode: Blade teeth face forward as shown in Figure 13B.
The DCS310 can accept all lengths of reciprocating blades. For best
results use 4" (102 mm) blades. Ensure the blade extends past the
shoe and the thickness of the workpiece during the cut. Use a longer
blade if needed. Whenever possible, the saw shoe must be held firmly
against the material being cut. This will prevent the saw from jumping
or vibrating and minimize blade breakage.

_VERTISSEMENT :afin de reduire le risque de blessures, life
le mode d'emploi de I'outil.
Avertissements de s_curit_ g_n_raux
pour les outils _lectriques
_AVERTISSEMENT! Life tous les avertissements de
s_curit_ et toutes les directives. Le non-respect des
avertissements et des directives pourrait se solder par un choc
dectrique, un incendie et/ou une blessure grave. 16
CONSERVER TOUSLES AVERTISSEMENTS
ET TOUTES LES DIRECTIVES POUR UN
USAGE ULTERIEUR
Le terme _outil dectrique _cite dans les avertissements se rapporte
votre outil dectrique a alimentation sur secteur (avec ill) ou par piles
(sans fil).
1) S#CURIT# DU LIEU DE TRAVAIL
a) Ten#" I'aire de travail propre et bien _clair_e. /es Iieux
encombres ou sombres sont propices aux accidents.
b) Ne pas faire fonctionner d'outils _lectriques clans un
milieu d_flagrant, tel qu'en presence de liquides, de
gaz ou de poussi_res inflammables. Les outi/s dectriques
produisent des etincelles qui pourraient enflammer la poussiere
ou les vapeurs.
c) E-Ioignerles enfants et les personnes aproximit_ pendant
I'utilisation d'un outil _lectrique. Une distraction pourrait en
faire perdre la ma_trise a I'utilisateur.
2) S#CURIT# EN MATIERE D'#LECTRICIT#
a) Les fiches des outils _lectriques doivent correspondre
la prise. Ne jamais modifier la fiche d'aucune faqon.
Ne jamais utiliser de fiche d'adaptation avec un outil
_lectrique mis a la terre. Le risque de choc dectrique sera
reduit par I'utilisation de fiches non modifiees correspondant
laprise.
b) Eviter tout contact physique avec des surfaces mises a la
terre comme des tuyaux, des radiateurs, des cuisini_res
et des r_frig_rateurs. Le risque de choc dectrique est plus
deve si votre corps est mis a la terre.
c) Ne pas exposer les outils _lectriques ala pluie ou
I'humidit_. La penetration de /'eau dans un outi/ dectrique
augmente le risque de choc dectrique.

d)Ne pas utiliser le cordon de fa_on abusive. Ne jamais
utiliser le cordon pour transporter, tirer ou d_brancher
un outil _lectrique. Tenir le cordon _loign_ de la chaleur,
de I'huile, des bords tranchants et des pi_ces mobiles.
Les cordons endommages ou enchev_tres augmentent les
risques de choc dectrique.
e) Pour I'utilisation d'un outil _lectrique a I'ext_rieur, se
servir d'une rallonge convenant a cette application.
L'utilisation d'une rallonge conque pour I'exterieur reduira les
risques de choc dectrique.
f) S'il est impossible d'_viter I'utilisation d'un outil
_lectrique dans un endro# humide, brancher I'outil dans
une prise ou sur un circuit d'alimentation dot_s d'un
disjoncteur de fuite a la terre (GFCI). L'utilisation de ce type
de disjoncteur reduit les risques de choc dectrique.
3) SI_CURITI_ PERSONNELLE
a) Etre vigilant, surveiller le travail effectu_ et faire preuve
de jugement Iorsqu'un outil _lectrique est utilis_. Ne
pas utiliser d'outil _lectrique en cas de fatigue ou sous
I'influence de drogues, d'alcool ou de m_dicaments. Un
simple moment d'inattention en utilisant un outil dectrique peut
entra_ner des blessures corporelles graves.
b) Utiliser des _quipements de protection individuelle.
Toujours porter une protection oculaire. L'uti/isation
d'equipements de protection comme un masque antipoussiere,
des chaussures antiderapantes, un casque de securite ou des
protecteurs auditifs Iorsque la situation le requiert reduira les
risques de blessures corporelles.
c) Emp_cher les d_marrages intempestifs. S'assurer que
I'interrupteur se trouve ala position d'arr_t avant de
relier I'outil aune source d'alimentation et/ou d'ins_rer
un bloc-piles, de ramasser ou de transporter I'outil.
Transporter un outil dectrique alors que le doigt repose sur
I'interrupteur ou brancher un outil dectrique dont I'interrupteur
est a la position de marche risque de provoquer un accident.
d) Retirer toute cl_ de r_glage ou cl_ avant de d_marrer
I'outil. Une c/e ou une c/e de reg/age attachee a une pattie
pivotante de I'outil dectrique peut provoquer des blessures
corporelles.
e) Ne pas trop tendre les bras. Conserver son _quilibre en
tout temps. Ce/a permet de mieux ma_triser /'outi/ dectrique
dans les situations imprevues.
0S'habiller de mani_re appropri_e. Ne pas porter de
v_tements amples ni de bijoux. Garder les cheveux, les
v_tements et les gants _I'_cart des pi_ces mobiles. Les
v_tements amp/es, /es bijoux ou /es cheveux longs risquent de
rester coinces dans les pieces mobiles.
g) Si des composants sent fournis pour le raccordement de
dispositifs de d_poussi_rage et de ramassage, s'assurer
que ceux-ci sent bien raccord_s et utilis_s. L'uti/isation
d'un dispositif de depoussierage peut reduire les dangers
engendres par les poussieres.
4} UTILISATION ET ENTRETIEN D'UN OUTIL leLECTRIQUE
a) Ne pas forcer un outil _lectrique. Utiliser I'outil _lectrique
appropri_ a I'application. L'outil electrique approprie
effectuera un meilleur travail, de faqon plus sore et a la vitesse
pour laquelle il a ete conqu.
b) Ne pas utiliser un outil _lectrique dont I'interrupteur
est d_fectueux. Tout outi/ dectrique dont /'interrupteur est
defectueux est dangereux et doit _tre repare.
c) D_brancher la fiche de la source d'alimentation et/ou du
bloc-piles de I'outil _lectrique avant de faire tout r_glage
ou changement d'accessoire ou avant de ranger I'outil.
Ces mesures preventives reduisent les risques de demarrage
accidentel de I'outil dectrique.
17

d)Ranger les outils _lectriques hors de la pottle des
enfants et ne permettre a aucune personne n'_tant
pas famili_re avec un outil _lectrique ou son mode
d'emploi d'utiliser cet outil. Les outi/s dectriques deviennent
dangereux entre les mains d'utilisateurs inexperimentes.
e) Entretien des outils _lectriques. V_rifier si les pi_ces
mobiles sont mal align_es ou coinc_es, si des pi_ces sont
bris_es ou pr_sentent toute autre condition susceptible
de nuire au bon fonctionnement de I'outil _lectrique.
En cas de dommage, faire r_parer I'outil _lectrique
avant toute nouvelle utilisation. Beaucoup d'accidents sont
causes par des outils dectriques mal entretenus.
f) S'assurer que les outils de coupe sont aiguis_s et
propres. Les outils de coupe bien entretenus et affOtes
sont moins susceptibles de se coincer et sont plus faciles
ma_triser.
q) Utiliser I'outil _lectrique, les accessoires, les forets,
etc. conform_ment aux pr_sentes directives en tenant
compte des conditions de travail et du travail _effectuer.
L'utilisation d'un outil dectrique pour toute operation autre que
celle pour laquelle ila ete conquest dangereuse.
5) UTILISATION ET ENTRETIEN DU BLOC-PILES
a) Ne recharger I'outil qu'au moyen du chargeur pr_cis_
par le fabricant. L'utilisation d'un chargeur qui convient
un type de bloc-piles risque de provoquer un incendie s'il est
utilise avec un autre type de b Ioc-piles.
b) Utiliser les outils _lectriques uniquement avec les blocs-
piles conqus a cet effet. L'utilisation de tout autre bloc-piles
risque de causer des blessures ou un incendie.
c) Lorsque le bloc-piles n'est pas utilis_, le tenir _loign_
des objets m_talliques, notamment des trombones, de
la monnaie, des cl_s, des clous, des vis ou autres petits
objets m_talliques qui peuvent _tablir une connexion
entre les deux bornes. Le court-circuit des bomes du bloc-
piles risque de provoquer des brOlures ou un incendie.
d) En cas d'utilisation abusive, le liquide peut gicler hors
du bloc-piles; _viter tout contact avec ce liquide. Si un
contact accidentel se produit, laver a grande eau. Si le
liquide entre en contact avec les yeux, obtenir _galement
des soins m_dicaux. Le /iquide qui gic/e hors du bloc-piles
peut provoquer des irritations ou des brOlures.
6) RI_PARATION
a) Faire r_parer routil _lectrique par un r_parateur
professionnel en n'utilisant que des pi_ces de rechange
identiques. Cela permettra de maintenir une utilisation
securitaire de I'outil dectrique.
R_gles particuli_res additionnelles de
s_curit_ propres aux scies alternatives
•Tenir I'outil par les surfaces isol_es pr_vues acet effet
pendant toute utilisation ob I'organe de coupe pourrait
entrer en contact avec des ills _lectriques caches. Tout
contact de I'organe de coupe avec un fil sous tension mettra
les parties metalliques exposees de I'outil sous tension et
dectrocutera I'utilisateur.
• Utilisez des serres de fixation ou un autre dispositif de
fixation permettant de soutenir et de retenir la piece sur
une plate-forme stable. Tenir la piece avec la main ou
contre son corps n'est pas suffisamment stable et risque
de provoquer une perte de maHrise de I'outil.
• Maintenir la scie fermement a deux mains lots de toute
coupe. Pendant la decoupe, la lame pourrait soudainement se
bloquer dans la piece a travailler et causer un rebond de la scie
vers I'utilisateur.
18

•Tenir/es mains b1'6cart de toute piece mobile. Ne jamais
approcher les mains des zones de coupes.
•Prendre des precautions suppl6mentaires pour d6couper
au-dessus de la t6te. Faire particulierement attention aux ills
dectriques qui pourraient y _tre dissimules. Anticiper toute chute
de branches ou debris.
•Ne pas utiliser cet outil pendant des p6riodes prolong6es.
Les vibrations causees par I'action de fonctionnement de I'outil
peuvent blesser en permanence les doigts, les mains et les bras.
Porter des gants pour amortir les vibrations, faire des pauses
frequentes et limiter le temps d'utilisation quotidien de I'outil.
iL4VERTISSEMENT : TOUJOURS porter des lunettes de securite.
Les lunettes de vue ne constituent PAS des lunettes de securit&
Utiliser egalement un masque facial ou anti-poussiere si I'operation
de decoupe genere de la poussiere. TOUJOURS UTILISER DE
L'EQUIPEMENT DE PROTECTION HOMOLOGUE:
• protection oculaire conforme a la norme ANSI Z87. 1 (CAN/
CSA Z94.3),
• protection auditive conforme a la normeANSI $12.6 ($3.19) et
• protection des voies respiratoires conformes aux normes
NIOSH/OSHA.
_J_AVERTISSEMENT :les scies, meules, ponceuses, perceuses ou
autres outils de construction peuvent produire des poussieres
contenant des produits chimiques reconnus par I'Etat califomien pour
causer cancers, malformations congenitales ou _tre nocifs au
systeme reproducteur. Parmi ces produits chimiques, on retrouve :
• Le plomb clans les peintures a base de plomb;
• La silice cristallisee dans les briques et le ciment, ou autres
produits de maqonnerie; et
• L'arsenic et le chrome dans le bois ayant subi un traitement
chimique.
Le risque associe aces expositions varie selon la frequence de ces
types de travaux. Pour reduire I'exposition aux produits chimiques :
travailler dans un local bien ventile et utiliser du materiel de securite
approuve, comme les masques antipoussieres specialement conqus
pour filtrer les particules microscopiques.
•Eviter le contact prolong6 avec la poussi_re provenant du
ponqage, du sciage, du meulage et du forage m6canique
ainsi que d'autres activit6s de construction. Porter des
v6tements de protection et laver les parties expos6es
au savon et aI'eau. La poussiere qui pourrait penetrer clans
la bouche et les yeux ou se deposer sur la peau peut favoriser
I'absorption de produits chimiques nocifs.
AAVERTISSEMENT :cet outil peut produire et repandre de la
poussiere susceptible de causer des dommages serieux et
permanents au systeme respiratoire. Toujours utiliser un appareil
respiratoire anti-poussieres approuve par le NIOSH ou I'OSHA.
Diriger les particules clans le sens oppose du visage et du corps.
_,4VERTISSEMENT : toujours porter une protection auditive
appropri6e conform6ment ala norme ANSI $12.6 ($3.19) lots
de I'utilisation du produit. Dans certaines conditions et selon la
duree d'utilisation, le bruit emis par ce produit peut contribuer a une
perte auditive.
J_4TTENTION : apr_s utilisation, ranger I'outil sur son c6t6 sur
une surface stable I_ ob il ne pourra faire ni tr6bucher ni
tomber personne. Certains outils equipes d'un large bloc-pile
peuvent tenir a la verticale sur ce demier mais ils sont alors facilement
destabilises.
