GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings, instruc-
tions, illustrations and specica-
tions 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-oper-
ated (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 atmo-
spheres, 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 operat-
ing 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 condi-
tions. 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 an 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 o󰀨-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.
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 o󰀨. 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 a󰀨ect 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 di󰀨erent 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.
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.

SPECIFIC SAFETY RULES FOR
ROTARY HAMMERS
Safety instructions for all operations
•Wear ear protectors. Exposure to noise can cause
hearing loss.
•Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
• Hold the power tool by insulated gripping sur-
faces, when performing an operation where the
cutting accessory may contact hidden wiring or
its own cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the power
tool “live” and could give the operator an electric
shock.
•Keep hands away from all cutting edges and
moving parts.
Safety instructions when using long drill bits
•Always start drilling at low speed and with the
bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting
in personal injury.
•Apply pressure only in direct line with the bit
and do not apply excessive pressure. Bits can
bend, causing breakage or loss of control, resulting
in personal injury.
•
WARNING
To reduce the risk of injury, when
working in dusty situations, wear
appropriate respiratory protection or use an
OSHA compliant dust extraction solution.
• Cut embedded rebar only if this operation does
not a󰀨ect the integrity of the building. If in doubt,
consult a structural engineer. Tool operator fully
responsible for adverse structural e󰀨ects.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
•
WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
•lead from lead-based paint
•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
lter out microscopic particles.
EXTENSION CORDS
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the greater
the capacity of the cord. For example, a 14 gauge
cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make
up the total length, be sure each cord contains at
least the minimum wire size required. If you are using
one extension cord for more than one tool, add the
nameplate amperes and use the sum to determine
the required minimum wire size.
Guidelines for Using Extension Cords
•If you are using an extension cord outdoors, be sure
it is marked with the su󰀩x “W-A” (“W” in Canada) to
indicate that it is acceptable for outdoor use.
•Be sure your extension cord is properly wired and in
good electrical condition. Always replace a damaged
extension cord or have it repaired by a qualied
person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

GROUNDING
WARNING
Improperly connecting the ground-
ing wire can result in the risk of
electric shock. Check with a qualied electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug pro-
vided with the tool. Never remove the grounding
prong from the plug. Do not use the tool if the
cord or plug is damaged. If damaged, have it
repaired by a MILWAUKEE service facility before
use. If the plug will not t the outlet, have a
proper outlet installed by a qualied electrician.
Grounded Tools (Three-Prong Plugs)
Tools marked “Grounding Required” have a three
wire cord and three prong grounding plug. The plug
must be connected to a properly grounded outlet
(See Figure A). If the tool should electrically mal-
function or break down, grounding provides a low
resistance path to carry electricity away from the
user, reducing the risk of electric shock.

Selecting Action
These MILWAUKEE Rotary Hammers
have three settings: hammering with
rotation, hammering-only, and chisel
adjustment.
1. Hammering with rotation. Use this
setting for drilling holes with drill
bits.
2. Hammering only. For use with
“hammering-only” accessories. Use
this setting for chiseling or setting
self-drilling anchors.
3. Chisel adjustment. Use this setting
to adjust the angle of the chisel
blade in relation to the tool. With a
chisel mounted in the tool:
• turn the knob to this setting
•rotate the chisel to the desired
angle
• turn the knob to "hammering-only".
NOTE: To engage the hammering mechanism, main-
tain pressure on the bit. When the pressure on the bit
is released, the hammering will stop.
Starting and Stopping
1. To start the tool, grasp the handle(s) rmly and
pull the trigger.
NOTE: An LED is turned on when the trigger is
pulled and will go o󰀨 shortly after the trigger is
released.
2. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Using the Chisel Lock
To activate the chisel lock:
1. Set the tool to chisel mode.
2. Pull and hold the trigger while sliding the chisel
lock button to the left.
3. Release trigger.
To deactivate the chisel lock, pull the trigger again.
Momentary Chisel
on lock
Operating
Position the tool, grasp the handles rmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been de-
signed to achieve top performance with only moder-
ate pressure. Let the tool do the work.
If the speed begins to drop o󰀨 when drilling large or
deep holes, pull the bit partially out of the hole while
the tool is running to help clear dust. Do not use water
to settle the dust since it will clog the bit utes and
tend to make the bit bind in the hole. If the bit should
bind, a built-in, non-adjustable slip clutch prevents
the bit from turning. If this occurs, stop the tool, free
the bit and begin again.
NOTE: The tool will shut o󰀨 and the service indicator
will ash if the handle begins to rotate during use.
Cycle through the trigger to continue operating.
WARNING
Applying greater pressure does not
increase the tool's e󰀨ectiveness.
If the applied working pressure is too high, the
shock absorber will be pushed together making
the vibrations to the handle noticeably stronger.
Operator Force
The Anti-Vibration System provides the operator with
comfort without sacricing power or performance.
Ideal operator force compresses the bellows slightly
and allows the tool to work aggressively while the
handle remains steady.
Excessive force compresses the bellows signicantly
and reduces vibration dampening. Users will be able
to feel the di󰀨erence and should adjust the force to
the handle accordingly.
Too little Correct Too much
force force force
Cold Starting
If this tool is stored for a long period of time or
at cold temperatures, it may not hammer ini-
tially because the lubrication has become stiff.
To warm up the tool:
1. Insert and lock a bit or chisel into the tool.
2. Pull the trigger and apply force to the bit or chisel
against a concrete or wood surface for a few
seconds. Release the trigger.
3. Repeat until the tool starts hammering. The colder
the tool is, the longer it will take to warm up.

Using Rotary Percussion Core Bits
Core Bits are useful for drilling large or long holes
in concrete. MILWAUKEE Heavy-Duty Core Bits
have heat-treated steel bodies with durable carbide
tips. These core bits are specially designed for fast,
accurate drilling with combined hammering and
rotary action.
1. Clean and lubricate the
threads on the adapter
and core bit to make
later removal easier.
Thread the adapter
shank to the rear of the
core bit.
2. Push the guide plate
onto the pointed end of
the center pin. Insert the
center pin and guide
plate assembly into the
core bit. Be sure the
small end of the center
pin is securely placed
into the hole in the cen-
ter of the core bit.
For LHS systems,
screw the threaded end
of the centering bit into
the core bit.
NOTE: If using an extension, first thread the
adapter shank to the extension. Then thread the
core bit to the extension.
3. Insert the adapter into the nose of the tool as
described in “Installing Bits and Chisels”. Set the
knob to the "hammering with rotation" setting.
4. Press the centering bit
rmly against your cen-
ter mark, hold the tool
rmly and pull the trig-
ger.
NOTE: If the
48-20-5099 threaded
stud is used, or a cen-
ter pin and guide plate
are not available, use
a template or notched
board to start the hole.
5. Start the tool. After drill-
ing to about the depth
of the core bit teeth,
remove the center pin
and guide plate from
the core bit (not nece-
sary for LHS system).
Resume drilling.
6. To change the core bit,
hold the tool upwards, pointing it away from your
body, and run it briey in forward to loosen the
core bit from the adapter.
NOTE: To make deeper holes, remove the core bit,
break and remove the core, then resume drilling.
When drilling long or deep holes, after each inch
of penetration pull the bit partially out of the hole
while the tool is running, to help clear dust from
the bit utes. Dust can clog the bit utes and can
make the bit bind in the hole. If this occurs, stop
the tool, free the bit and begin again.
Drilling Large Diameter Holes
with Core Bits
When drilling holes with large diameter core bits, dust
may build up in the cut and can cause the tool to
stall, bind, or cut slowly. By creating an opening for
the dust to escape, drilling time, bit stress, and tool
stress can be reduced.

5. Drill a perpendicular hole through
the kerf of the large hole.
• Depending on the location of the
work, the hole should either break
through the other side of the hole/
oor or extend 4"-5" past the end
of the workpiece (such as into the
dirt below a concrete slab).
• If dust builds up in the hole, vac-
uum it out and continue drilling.
• If drilling through a wall, the hole
for dust should be drilled on

with the hammer running. This
will remove some of the dust
and debris from the cut. Repeat
this for every inch of drilling. If
necessary, vacuum dust and
debris from the cut and sur-
rounding area.
7. For core bits, once the maximum
core bit depth is drilled, the core
must be broken and removed.
• Install a chisel bit.
• Place the chisel into the hole
kerf.
• Chisel down into the kerf at
several points until the core is loose or broken.
• Remove the core and vacuum/remove any re-
maining dust and debris.
• Install the core bit and continue the cut.

mering only. Set the
anchor on your mark
and hammer until the
teeth have penetrated
the concrete.
3. Set the knob for ham-
mering with rotation
and drill until the chuck
is 1/8" above the con-
crete.
NOTE: It may be nec-
essary to clean dust
and cuttings from the
anchor several times
while drilling the hole.
Use caution to prevent
exposure to dust.
4. Remove the anchor
from the hole while the
tool is running. Clean
the dust and cuttings
from the anchor by
pointing it downward and turning the tool on and
o󰀨 several times. Clean the dust out of the hole
with a vacuum cleaner or blowout bulb.
5. Place the expansion plug into the anchor and insert
the anchor into the hole. Switch the knob back to

RÈGLES DE SÉCURITÉ
GÉNÉRALES RELATIVES AUX
OUTILS ÉLECTRIQUES
AVERTISSEMENT
Lire toutes les consignes
de sécurité, consignes,
illustrations et spécications fournies avec cet
outil électrique. Ne pas suivre l’ensemble des règles
et instructions peut entraîner une électrocution, un
incendie ou des blessures graves. Conserver les
règles et les instructions à des ns de référence
ultérieure. Le terme «outil électrique» gurant dans
les avertissements ci-dessous renvoie à l’outil élec-
trique à alimentation par le réseau (à cordon) ou par
batterie (sans l).
SÉCURITÉ DU LIEU DE TRAVAIL
• Veillez à ce que l’aire de travail soit propre et
bien éclairée. Le désordre et le manque de lumière
favorisent les accidents.
• Ne pas utiliser d’outils électriques dans des at-
mosphères explosives, par exemple en présence
de liquides, gaz ou poussières inammables. Les
outils électriques produisent des étincelles risquant
d'enammer les poussières ou vapeurs.
• S’assurer que les enfants et les curieux se trou-
vent à une bonne distance au moment d’utiliser
un outil électrique. Les distractions peuvent causer
une perte de contrôle.
SÉCURITÉ ÉLECTRIQUE
• Les ches des outils électriques doivent cor-
respondre à la prise secteur utilisée. Ne jamais
modier la che, de quelque façon que ce soit.
Ne jamais utiliser d'adaptateurs de che avec
des outils mis à la terre. Les ches et prises non
modiées réduisent le risque de choc électrique.
•Éviter tout contact avec des surfaces mises à
la terre comme des tuyaux, des radiateurs, des
cuisinières et des réfrigérateurs. Le risque de
choc électrique est accru lorsque le corps est mis
à la terre.
• Ne pas exposer les outils électriques à l'eau ou
l'humidité. La pénétration d’eau dans ces outils
accroît le risque de choc électrique.
•Ne pas maltraiter le cordon d'alimentation.
Ne jamais utiliser le cordon d’alimentation
pour transporter l’outil électrique et ne jamais
débrancher ce dernier en tirant sur le cordon.
Garder le cordon à l'écart de la chaleur, de
l'huile, des objets tranchants et des pièces en
mouvement. Un cordon endommagé ou emmêlé
accroît le risque de choc électrique.
• Pour les travaux à l’extérieur, utiliser un cordon
spécialement conçu à cet e󰀨et. Utiliser un cordon
conçu pour l'usage extérieur réduit les risques de
choc électrique.
• Si l’utilisation d’un outil électrique est inévitable
dans un endroit humide, utiliser une source
d’alimentation munie d’un disjoncteur de fuite
de terre. L’utilisation d’un disjoncteur de fuite de
terre réduit le risque de choc électrique.
SÉCURITÉ INDIVIDUELLE
•Rester attentif, prêter attention au travail et faire
preuve de bon sens lors de l'utilisation de tout
outil électrique. Ne pas utiliser cet appareil en
cas de fatigue ou sous l’inuence de l’alcool,
de drogues ou de médicaments. Un moment
d’inattention pendant l’utilisation d’un outil électrique
peut entraîner des blessures graves.
• Porter l’équipement de protection individuel
requis. Toujours porter une protection oculaire.
Selon les conditions, porter aussi un masque anti-
poussières, des bottes de sécurité antidérapantes,
un casque protecteur ou une protection auditive an
de réduire les blessures.
• Empêcher les démarrages accidentels. S’assurer
que la gâchette est en position d’arrêt avant de
brancher l’outil à une source de courant, d’insérer
la batterie, de le ramasser ou de le transporter.
Le fait de transporter un outil électrique en gardant
le doigt sur la gâchette ou de mettre sous tension
un outil électrique lorsque la gâchette est en position
de marche favorise les accidents.
• Retirer les clés de réglage avant de mettre l’outil
en marche. Une clé laissée sur une pièce rotative
de l’outil peut causer des blessures.
• Ne pas travailler hors de portée. Toujours se tenir
bien campé et en équilibre. Une bonne stabilité
procure un meilleur contrôle de l’outil électrique en
cas d’imprévus.
• Porter une tenue appropriée. Ne porter ni vête-
ments amples, ni bijoux. Garder les cheveux et
les vêtements à l’écart des pièces en mouvement.
Les vêtements ottants, les bijoux ou les cheveux
longs risquent d’être happés par les pièces en
mouvement.
• Si les outils sont équipés de dispositifs de
dépoussiérage, s'assurer qu'ils sont connectés
et correctement utilisés. L’utilisation d’un collecteur
de poussière permet de réduire les dangers liés à
la poussière.
• Ne pas laisser la familiarité avec l'outil acquise
par une utilisation fréquente vous rendre su󰀩sant
et vous amener à ignorer les règles de sécurité.
Une utilisation négligée peut causer une blessure
grave en une fraction de seconde.
UTILISATION ET ENTRETIEN
DE L’OUTIL ÉLECTRIQUE
• Ne pas forcer l'outil électrique. Utiliser l'outil
électrique approprié pour l'application. Un outil
électrique approprié exécutera le travail mieux et
de façon moins dangereuse s’il est utilisé dans les
limites prévues.
• Ne pas utiliser l'outil électrique si le commutateur
ne permet pas de le mettre en marche ou de
l'arrêter. Tout outil électrique qui ne peut pas être
contrôlé par son commutateur est dangereux et doit
être réparé.
• Débrancher l'outil et/ou retirer le bloc-piles, si
possible, avant d’e󰀨ectuer des réglages, de
changer d’accessoire ou de remiser l’outil. Ces
mesures de sécurité préventives réduisent les risques
de démarrage accidentel de l'outil.
• Entreposer l’outil électrique hors de la portée des
enfants et interdire à quiconque de l’utiliser si la
personne ne connaît pas bien le produit ou les
instructions. Les outils électriques sont dangereux
dans les mains d’utilisateurs novices.
• Entretenir les outils électriques et les acces-
soires. Vérier qu'aucune pièce mobile n'est mal
alignée ou bloquée, qu'aucune pièce n'est brisée
et s'assurer qu'aucun autre problème risque
d'a󰀨ecter le bon fonctionnement de l'outil. En
cas de dommages, faire réparer l’outil avant de
l’utiliser. Plusieurs accidents sont causés par des
produits mal entretenus.

10
• Garder les outils bien a󰀨ûtés et propres. Des
outils correctement entretenus et dont les tranchants
sont bien a󰀨ûtés risquent moins de se bloquer et
sont plus faciles à contrôler.
• Utiliser l’outil électrique, les accessoires, les
embouts etc. conformément à ces instructions
en tenant compte des conditions de travail et de
la tâche à e󰀨ectuer. L'usage d'un outil électrique
pour des applications pour lesquelles il n'est pas
conçu peut être dangereux.
• Garder les poignées et les surfaces de préhension
sèches, propres et exemptes d’huile ou de graisse.
Des poignées et des surfaces de préhension glis-
santes ne permettent pas de manipuler et de contrôler
l'outil en toute sécurité en cas de situation imprévue.
ENTRETIEN
• Les réparations de l’outil électrique doivent
être conées à un technicien qualié, utilisant
exclusivement des pièces identiques à celles
d’origine. Le maintien de la sûreté de l’outil électrique
sera ainsi assuré.
RÈGLESDESÉCURITÉSPÉCFIQUES
PARA MARTEAU ROTATIF
Consignes de sécurité pour toutes les opérations
•Porter des protège-oreilles avec un marteau
perforateur. Une exposition au bruit peut provoquer
une perte auditive.
• Utiliser les poignées auxiliaires fournies avec
l’outil. Une perte de contrôle peut provoquer des
blessures.
•Tenez l'outil électrique par des surfaces de prise
isolées si, accessoire de coupe risque d'entrer
en contact avec des l cachés ou avec son propre
cordon d’alimentation .Le contact avec un lsous
met les parties métalliques exposées de l'outil
sous tension, ce qui inigeraun choc électrique à
l'opérateur.
•Garder les mains à l’écart des rebords tran-
chants et des pièces en mouvement.
Consignes de sécurité lors de l'utilisation de
forets longs
•Toujours commencer à percer à une faible vi-
tesse, en tenant la pointe de la mèche toujours
en contact avec la pièce. À des vitesses plus
hautes, il est possible que la mèche se torde si
elle est laissée tourner librement sans faire aucun
contact avec la pièce, en provoquant des blessures
physiques.
Exercer de la pression uniquement sur la mèche
et ne pas exercer une pression excessive. Les
mèches peuvent se tordre, en provoquant une
rupture ou la perte de contrôle, ce qui pourra ainsi
causer des blessures physiques.
•
AVERTISSEMENT
An de minimiser le risque
de blessures, lorsque de
travaux sont faits dans de situations poussié-
reuses, porter une protection respiratoire ou
bien, utiliser une solution d'extraction de
poussière conforme aux normes OSHA.
• Couper les barres d’armature intégrées unique-
ment si l’opération ne porte pas atteinte à
l’intégrité du bâtiment. En cas de doute, con-
tacter un ingénieur en structures. L’utilisateur
de l’outil assume la pleine responsabilité pour
les e󰀨ets structuraux nuisibles.
• Toujours faire preuve de bons sens et procéder
avec prudence lors de l’utilisation d’outils. C’est
impossible de prévoir toutes les situations dont le
résultat est dangereux. Ne pas utiliser cet outil si vous
ne comprenez pas ces instructions d’opération ou si
vous pensez que le travail dépasse votre capacité ;
veuillez contacter Milwaukee Tool ou un professionnel
formé pour recevoir plus d’information ou formation.
•Maintenir en l’état les étiquettes et les plaques
d’identication.Des informations importantes y
gurent. Si elles sont illisibles ou manquantes,
contacter un centre de services et d’entretien
MILWAUKEE pour un remplacement gratuit.
•
AVERTISSEMENT
Certaines poussières gé-
nérées par les activités de
ponçage, de coupe, de rectication, de perforage
et d’autres activités de construction contiennent des
substances considérées être la cause de malforma-
tions congénitales et de troubles de l’appareil repro-
ducteur. Parmi ces substances gurent:
•le plomb contenu dans les peintures à base de
plomb;
•la silice cristalline des briques, du ciment et d’autres
matériaux de maçonnerie, ainsi que
• l’arsenic et le chrome des sciages traités chimiquement.
Les risques encourus par l’opérateur envers ces
expositions varient en fonction de la fréquence de
ce type de travail. Pour réduire l’exposition à ces
substances chimiques, l’opérateur doit: travailler
dans une zone bien ventilée et porter l’équipement de
sécurité approprié, tel qu’un masque anti-poussière
spécialement conçu pour filtrer les particules
microscopiques.
CORDONS DE RALLONGE
Si l’emploi d’un cordon de rallonge est nécessaire,
un cordon à trois ls doit être employé pour les outils
mis à la terre. Pour les outils à double isolation, on
peut employer indi󰀨éremment un cordon de rallonge
à deux ou trois ls. Plus la longueur du cordron entre
l’outil et la prise de courant est grande, plus le calibre
du cordon doit être élevé. L’utilisation d’un cordon de
rallonge incorrectement calibré entraîne une chute
de voltage résultant en une perte de puissance qui
risque de détériorer l’outil. Reportez-vous au tableau
ci-contre pour déterminer le calibre minimum du cor-
don. Moins le calibre du l est élevé, plus sa conduc-
tivité est bonne. Par exemple, un cordon de calibre
14 a une meilleure conductivité qu’un cordon de
calibre 16. Lorsque vous utilisez plus d’une rallonge
pour couvrir la distance, assurez-vous que chaque
cordon possède le calibre minimum requis. Si vous
utilisez un seul cordon pour brancher plusieurs outils,
additionnez le chi󰀨re d’intensité (ampères) inscrit sur
la che signalétique de chaque outil pour obtenir le
calibre minimal requis pour le cordon.
Directives pour l’emploi des cordons de rallonge
•Si vous utilisez une rallonge à l’extérieur, assurez-
vous qu’elle est marquée des sigles « W-A »(« W »
au Canada) indiquant qu’elle est adéquate pour
usage extérieur.
•Assurez-vous que le cordon de rallonge est correcte-
ment câblé et en bonne condition. Remplacez tout cor-
don derallonge détérioré ou faites-le remettre en état
par une personne compétente avant de vous en servir.
• Tenez votre cordon de rallonge à l’écart des objets
ranchants, des sources de grande chaleur et des
endroits humides ou mouillés.
