GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below 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 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.
f ) 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.
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.
h ) 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
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 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.
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 and accesories. 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.
f ) 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
ENGLISH
3
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.
h ) 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.
5) 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.
SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Safety Warnings Common for Grinding,
Sanding, Wire Brushing, Polishing or
Abrasive, Cutting-Off Operations
a ) This power tool is intended to function as a
grinder, sander, wire brush, polisher or cut-off
tool. Read all safety warnings, instructions,
illustrations and specifications provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/or
seriousinjury.
b ) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safeoperation.
c ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the
power tool. Accessories running faster than their
rated speed can break and flyapart.
d ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot
be adequately guarded orcontrolled.
e ) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbor hole of the
accessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss ofcontrol.
f ) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for loose
or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an
undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged
accessories will normally break apart during this
testtime.
g ) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable
of stopping flying debris generated by various
operations. The dust mask or respirator must
be capable of filtrating particles generated by
your operation. Prolonged exposure to high intensity
noise may cause hearingloss.
h ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area ofoperation.
i ) Hold the power tool by insulated gripping
surfaces only, 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.
j ) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the
spinningaccessory.
k ) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull the
power tool out of yourcontrol.
l ) Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into yourbody.
m ) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electricalhazards.
n ) Do not operate the power tool near flammable
materials. Sparks could ignite thesematerials.
o ) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution orshock.
p ) Do not use Type 11 (flaring cup) wheels on this
tool. Using inappropriate accessories can result
ininjury.
q ) Always use side handle. Tighten the handle
securely. The side handle should always be used to
maintain control of the tool at alltimes.
r ) When starting the tool with a new or
replacement wheel, or a new or replacement
wire brush installed, hold the tool in a well
protected area and let it run for one minute. If
ENGLISH
4
the wheel has an undetected crack or flaw, it
should burst in less than one minute. If the wire
brush has loose wires, they will be detected.
Never start the tool with a person in line with the
wheel. This includes theoperator.
s ) Use of accessories not specified in this manual
is not recommended and may be hazardous.
Use of power boosters that would cause the tool
to be driven at speeds greater than its rated speed
constitutesmisuse.
t ) Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves
it unstable and may lead to loss ofcontrol.
u ) Avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the
wheel for cracks orflaws.
v ) Always handle and store wheels in a carefulmanner.
w ) 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.
x ) Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be
caught in movingparts.
Causes and Operator Prevention
of Kickback
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the accessory’s rotation
at the point of thebinding.
For example, if an abrasive wheel is snagged or pinched by
the workpiece, the edge of the wheel that is entering into the
pinch point can dig into the surface of the material causing
the wheel to climb out or kick out. The wheel may either jump
toward or away from the operator, depending on direction
of the wheel’s movement at the point of pinching. Abrasive
wheels may also break under theseconditions.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip on the power tool and
position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start up. The operator can
control torque reaction or kickback forces, if proper
precautions aretaken.
b ) Never place your hand near the rotating
accessory. Accessory may kickback over yourhand.
c ) Do not position your body in the area where
power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel’s
movement at the point ofsnagging.
d ) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have
a tendency to snag the rotating accessory and cause
loss of control orkickback.
e ) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create frequent
kickback and loss ofcontrol.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations
a ) Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded
and areunsafe.
b ) The grinding surface of center depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot be
adequatelyprotected.
c ) The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed towards
the operator. The guard helps to protect the operator
from broken wheel fragments, accidental contact with
wheel and sparks that could igniteclothing.
d ) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them toshatter.
e ) Always use undamaged wheel flanges that
are of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheelflanges.
f ) Do not use worn down wheels from larger power
tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
mayburst.
Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations
a ) Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheelbreakage.
ENGLISH
5
b ) Do not position your body in line with and
behind the rotating wheel. When the wheel, at the
point of operation, is moving away from your body,
the possible kickback may propel the spinning wheel
and the power tool directly atyou.
c ) When wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheelbinding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
theworkpiece.
e ) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the edge of
the workpiece on both sides of thewheel.
f ) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can causekickback.
Safety Warnings Specific for Sanding
Operations
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc orkickback.
Safety Warnings Specific for Polishing
Operations
a ) Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment strings.
Loose and spinning attachment strings can entangle
your fingers or snag on theworkpiece.
Safety Warnings Specific for Wire
Brushing Operations
a ) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load
to the brush. The wire bristles can easily penetrate
light clothing and/orskin.
b ) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work and
centrifugalforces.
c ) Safety goggles or safety glasses with side shields
and a full face shield compliant with ANSI Z87.1
MUST be worn by the operator and others that
are within 50' (15.2 m) of the use of thisproduct.
Additional Safety Information
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 S12.6 (S3.19) hearing protection,
NIOSH/OSHA/MSHA respiratoryprotection.
WARNING: 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 use
NIOSH/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 S12.6 (S3.19)
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. Some tools with large
battery packs will stand upright on the battery pack
but may be easily knockedover.
Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be
caught in movingparts.

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

To perform work on the surface of a workpiece:
1. Allow the tool to reach full speed before touching the
tool to the worksurface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Material removal rate
is greatest when the tool operates at highspeed.
Angle
Fig. I
3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particularfunction.
Function Angle
Grinding 20˚-30˚
Sanding with Flap Disc 5˚-10˚
Sanding with Backing Pad 5˚-15˚
Wire Brushing 5˚-10˚
4. Maintain contact between the edge of the wheel and
the worksurface.
- If grinding, sanding with flap discs or wire brushing
move the tool continuously in a forward and
back motion to avoid creating gouges in the
worksurface.
- If sanding with a backing pad, move the tool
constantly in a straight line to prevent burning and
swirling of worksurface.
NOTE: Allowing the tool to rest on the work surface without
moving will damage the workpiece.
5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying itdown.
CAUTION: Use extra care when working over an
edge, as a sudden sharp movement of grinder may
beexperienced.
Precautions To Take When Working on
a Painted Workpiece
1. Sanding or wire brushing of lead based paint is NOT
RECOMMENDED due to the difficulty of controlling
the contaminated dust. The greatest danger of lead
poisoning is to children and pregnantwomen.
2. Since it is difficult to identify whether or not a paint
contains lead without a chemical analysis, we
recommend the following precautions when sanding
any paint:
Personal Safety
1. No children or pregnant women should enter the work
area where the paint sanding or wire brushing is being
done until all clean up iscompleted.
2. A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced
daily or whenever the wearer has difficultybreathing.
NOTE: Only those dust masks suitable for working
with lead paint dust and fumes should be used.
Ordinary painting masks do not offer this protection.
See your local hardware dealer for the proper N.I.O.S.H.
approvedmask.
3. NO EATING, DRINKING or SMOKING should be done in
the work area to prevent ingesting contaminated paint
particles. Workers should wash and clean up BEFORE
eating, drinking or smoking. Articles of food, drink, or
smoking should not be left in the work area where dust
would settle onthem.
Environmental Safety
1. Paint should be removed in such a manner as to
minimize the amount of dustgenerated.
2. Areas where paint removal is occurring should be sealed
with plastic sheeting of 4 milsthickness.
3. Sanding should be done in a manner to reduce tracking
of paint dust outside the workarea.
Cleaning and Disposal
1. All surfaces in the work area should be vacuumed
and thoroughly cleaned daily for the duration of
the sanding project. Vacuum filter bags should be
changedfrequently.
2. Plastic drop cloths should be gathered up and disposed
of along with any dust chips or other removal debris.
They should be placed in sealed refuse receptacles and
disposed of through regular trash pick-upprocedures.
During clean up, children and pregnant women should
be kept away from the immediate workarea.
3. All toys, washable furniture and utensils used by
children should be washed thoroughly before being
usedagain.
Edge Grinding and Cutting (Fig. J)
WARNING: Do not use edge grinding/cutting wheels
for surface grinding applications because these wheels
are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury
mayresult.
CAUTION: Wheels used for edge grinding and cutting
may break or kick back if they bend or twist while
the tool is being used. In all edge grinding/cutting
operations, the open side of the guard must be
positioned away from theoperator.
NOTICE: Edge grinding/cutting with a Type27 wheel
must be limited to shallow cutting and notching—
less than 13mm in depth when the wheel is new.
Reduce the depth of cutting/notching equal to the
reduction of the wheel radius as it wears down. Refer
to the Accessories Chart for more information. Edge
grinding/cutting with a Type 41 wheel requires usage
of a Type 1guard.
1. Allow the tool to reach full speed before touching the
tool to the worksurface.
ENGLISH
12
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting rate
is greatest when the tool operates at highspeed.
3. Position yourself so that the open-underside of the
wheel is facing away fromyou.
4. Once a cut is begun and a notch is established in
the workpiece, do not change the angle of the cut.
Changing the angle will cause the wheel to bend and
may cause wheel breakage. Edge grinding wheels
are not designed to withstand side pressures caused
bybending.
Fig. J
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
itdown.
MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Cleaning
WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performingthis.
WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of
the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth dampened

AVERTISSEMENTS GÉNÉRAUX SUR LA
SÉCURITÉ DES OUTILS
AVERTISSEMENT: lisez tous les avertissements de
sécurité, toutes les instructions, les illustrations
et les caractéristiques fournis avec cet outil
électrique. Ne pas suivre toutes les instructions
comprises aux présentes peut conduire à un choc
électrique, un incendie et/ou des blessuresgraves.
CONSERVER TOUS LES
AVERTISSEMENTS ET TOUTES
LES DIRECTIVES POUR UN
USAGE ULTÉRIEUR
Le terme « outil électrique » cité dans les avertissements se
rapporte à votre outil électrique à alimentation sur secteur
(avec fil) ou par piles (sans fil).
1) Sécurité du lieu de travail
a ) Tenir l’aire de travail propre et bien éclairée.
Les lieux encombrés ou sombres sont propices
auxaccidents.
b ) Ne pas faire fonctionner d’outils électriques
dans un milieu déflagrant, tel qu’en présence de
liquides, de gaz ou de poussières inflammables.
Les outils électriques produisent des étincelles qui
pourraient enflammer la poussière ou lesvapeurs.
c ) Éloigner les enfants et les personnes à proximité
pendant l’utilisation d’un outil électrique.
Une distraction pourrait en faire perdre la maîtrise
àl’utilisateur.
2) Sécurité en matière d’électricité
a ) Les fiches des outils électriques doivent
correspondre à la prise. Ne jamais modifier la
fiche d’aucune façon. Ne jamais utiliser de fiche
d’adaptation avec un outil électrique mis à la
terre. Le risque de choc électrique sera réduit par
l’utilisation de fiches non modifiées correspondant
à laprise.
b ) Éviter tout contact physique avec des surfaces
mises à la terre comme des tuyaux, des
radiateurs, des cuisinières et des réfrigérateurs.
Le risque de choc électrique est plus élevé si votre corps
est mis à laterre.
c ) Ne pas exposer les outils électriques à la pluie ou
à l’humidité. La pénétration de l’eau dans un outil
électrique augmente le risque de chocélectrique.
d ) Ne pas utiliser le cordon de façon abusive.
Ne jamais utiliser le cordon pour transporter,
tirer ou débrancher un outil électrique. Tenir le
cordon éloigné de la chaleur, de l’huile, des bords
tranchants et des pièces mobiles. Les cordons
endommagés ou enchevêtrés augmentent les risques
de chocélectrique.
e ) Pour l’utilisation d’un outil électrique à
l’extérieur, se servir d’une rallonge convenant à
cette application. L’utilisation d’une rallonge conçue
pour l’extérieur réduira les risques de chocélectrique.
f ) S’il est impossible d’éviter l’utilisation d’un
outil électrique dans un endroit humide,
brancher l’outil dans une prise ou sur un circuit
d’alimentation dotés d’un disjoncteur de fuite à
la terre (GFCI). L’utilisation de ce type de disjoncteur
réduit les risques de chocélectrique.
3) Sécurité personnelle
a ) Être vigilant, surveiller le travail effectué et faire
preuve de jugement lorsqu’un outil électrique
est utilisé. Ne pas utiliser d’outil électrique en
cas de fatigue ou sous l’influence de drogues,
d’alcool ou de médicaments. Un simple moment
d’inattention en utilisant un outil électrique peut
entraîner des blessures corporellesgraves.
b ) Utiliser des équipements de protection
individuelle. Toujours porter une protection
oculaire. L’utilisation d’équipements de protection
comme un masque antipoussière, des chaussures
antidérapantes, un casque de sécurité ou des
protecteurs auditifs lorsque la situation le requiert
réduira les risques de blessurescorporelles.
c ) Empêcher les démarrages intempestifs. S’assurer
que l’interrupteur se trouve à la position
d’arrêt avant de relier l’outil à une source
d’alimentation et/ou d’insérer un bloc-piles, de
ramasser ou de transporter l’outil. Transporter
un outil électrique alors que le doigt repose sur
l’interrupteur ou brancher un outil électrique dont
l’interrupteur est à la position de marche risque de
provoquer unaccident.
d ) Retirer toute clé de réglage ou clé avant de
démarrer l’outil. Une clé ou une clé de réglage
attachée à une partie pivotante de l’outil électrique
peut provoquer des blessurescorporelles.
e ) Ne pas trop tendre les bras. Conserver
son équilibre en tout temps. Cela permet
de mieux maîtriser l’outil électrique dans les
situationsimprévues.
f ) S’habiller de manière appropriée. Ne pas porter
de vêtements amples ni de bijoux. Garder les
cheveux, les vêtements et les gants à l’écart des
pièces mobiles. Les vêtements amples, les bijoux ou
les cheveux longs risquent de rester coincés dans les
piècesmobiles.
g ) Si des composants sont fournis pour le
raccordement de dispositifs de dépoussiérage
et de ramassage, s’assurer que ceux-ci sont bien
raccordés et utilisés. L’utilisation d’un dispositif de
dépoussiérage peut réduire les dangers engendrés par
lespoussières.
h ) Ne pas laisser votre connaissance acquise suite
l’utilisation fréquente des outils vous permettre
de baisser la garde et ignorer les principes de
sécurité de l’outil. Un acte irréfléchi peut causer une
blessure grave en une fraction de seconde.
4) Utilisation et entretien d’un
outil électrique
a ) Ne pas forcer un outil électrique. Utiliser l’outil
électrique approprié à l’application. L’outil
électrique approprié effectuera un meilleur travail,
de façon plus sûre et à la vitesse pour laquelle il a
étéconçu.
FRANÇAIS
16
b ) Ne pas utiliser un outil électrique dont
l’interrupteur est défectueux. Tout outil électrique
dont l’interrupteur est défectueux est dangereux et
doit êtreréparé.
c ) Débranchez la fiche de la prise électrique et, si
amovible, retirez le bloc-piles de l’outil avant
d’effectuer tout ajustement, changement et
entreposage de celui-ci. Ces mesures préventives
réduisent les risques de démarrage accidentel de
l’outilélectrique.
d ) Ranger les outils électriques hors de la portée
des enfants et ne permettre à aucune personne
n’étant pas familière avec un outil électrique ou
son mode d’emploi d’utiliser cet outil. Les outils
électriques deviennent dangereux entre les mains
d’utilisateursinexpérimentés.
e ) Gardez les poignées et surfaces d’emprise
propres et libres de tout produit lubrifiant.
Vérifier si les pièces mobiles sont mal alignées ou
coincées, si des pièces sont brisées ou présentent
toute autre condition susceptible de nuire au bon
fonctionnement de l’outil électrique. En cas de
dommage, faire réparer l’outil électrique avant
toute nouvelle utilisation. Beaucoup d’accidents
sont causés par des outils électriques malentretenus.
f ) S’assurer que les outils de coupe sont aiguisés et
propres. Les outils de coupe bien entretenus et affûtés
sont moins susceptibles de se coincer et sont plus
faciles àmaîtriser.
g ) Utiliser l’outil électrique, les accessoires, les
forets, etc. conformément aux présentes
directives en tenant compte des conditions de
travail et du travail à effectuer. L’utilisation d’un
outil électrique pour toute opération autre que celle
pour laquelle il a été conçu estdangereuse.
h ) Garder vos mains et les surfaces de prise sèches,
propres et libres de graisse et de poussière. Les
mains et les surfaces de prise glissante ne permettent
pas la manutention et le contrôle sécuritaires de l’outil
dans les situationsimprévues.
5) Réparation
a ) Faire réparer l’outil électrique par un réparateur
professionnel en n’utilisant que des pièces de
rechange identiques. Cela permettra de maintenir
une utilisation sécuritaire de l’outilélectriques.
CONSIGNES DE SÉCURITÉ POUR TOUTES LES
OPÉRATIONS
Avertissements de sécurité communs
à toutes les opérations de meulage,
ponçage, brossage à l’aide d’une brosse
métallique, polissage ou de coupe
a ) Cet outil électrique est conçu pour fonctionner
comme une meule, une ponceuse, une brosse
métallique, une polisseuse ou un outil de coupe.
Lire tous les avertissements de sécurité, les
directives, les illustrations et les spécifications
fournies avec cet outil électrique. Négliger de
suivre l’ensemble des directives suivantes pourrait
entraîner des risques de choc électrique, d’incendie et/
ou de blessuresgraves.
b ) Ne pas utiliser d’accessoire non conçu
spécifiquement pour cet outil ou qui n’aurait pas
reçu une approbation spécifique du fabricant
de l’outil. En effet, il est parfois possible de fixer
un accessoire à l’outil électrique; toutefois, cela ne
garantit pas une utilisationsécuritaire.
c ) Le régime nominal de l’accessoire doit être au
moins égal au régime maximal inscrit sur l’outil
électrique. Les accessoires soumis à un régime plus
élevé que celui pour lequel ils sont conçus peuvent se
briser et êtreprojetés.
d ) Le diamètre externe et l’épaisseur de l’accessoire
doivent être adéquats pour la capacité de l’outil
électrique. Il est impossible de protéger l’utilisateur
d’un bris d’accessoire de mauvais calibre ou de le
maîtrisercorrectement.
e ) Les raccords filetés d’accessoires doivent
correspondre au filetage de la broche de la
meuleuse. Pour les accessoires à installation
par brides, l’alésage central de l’accessoire
doit correspondre au diamètre de référence
de la bride. Les accessoires ne correspondant pas
au dispositif d’installation de l’outil électrique ne
tourneront pas correctement, vibreront de façon
excessive et pourront causer la perte de contrôle
de l’outil.
f ) Ne jamais utiliser un accessoire endommagé.
Avant toute utilisation, inspecter la meule
abrasive à la recherche d’éclats et de fissures; le
tampon pour tout signe de fissures, déchirures
ou d’usure excessive; et la brosse métallique,
pour déceler s’il y a des fils métalliques fissurés
ou détachés. En cas de chute de l’outil ou
de l’accessoire, les inspecter à la recherche
de dommages ou insérer un accessoire non
endommagé. Après l’inspection et l’insertion
d’un accessoire, se positionner (l’utilisateur
ou quiconque aux alentours) hors du plan de
rotation de l’accessoire et faire tourner, pendant
une minute, l’outil électrique à plein régime, à
vide. Normalement, tout accessoire endommagé se
brisera au cours de cette période d’essai.
g ) Porter un équipement de protection individuelle.
Utiliser un masque facial, des lunettes de
sécurité ou des lunettes protectrices en fonction
de l’application. Au besoin, porter un masque
antipoussières, des protecteurs auditifs, des
gants et un tablier d’atelier capable d’arrêter
de petits fragments d’abrasifs ou de pièces. La
protection oculaire doit être en mesure d’arrêter tout
débris produit par les diverses opérations et le masque
antipoussières ou le respirateur, de filtrer les particules
produites par l’opération en cours. Une exposition
prolongée à un bruit d’intensité élevée pourrait causer
une perteauditive.
FRANÇAIS
17
h ) Éloigner tout observateur à une distance
sécuritaire de la zone de travail. Toute personne
qui pénètre dans la zone de travail devra
également porter un équipement de protection
individuelle. Il est possible qu’un fragment de pièce
ou un accessoire brisé soit projeté et provoque des
blessures au-delà de la zone immédiate detravail.
i ) Tenir l’outil électrique par les surfaces isolées
prévues à cet effet pendant toute utilisation où
l’organe de coupe pourrait entrer en contact
avec des fils électriques cachés ou son propre
cordon. Tout contact de l’organe de coupe avec un fil
sous tension mettra les parties métalliques exposées
de l’outil électrique sous tension et électrocutera
l’utilisateur.
j ) Positionner le cordon d’alimentation hors
d’atteinte de l’accessoire en mouvement. En
cas de perte de maîtrise, il est possible de couper
ou d’effilocher le cordon et la main ou le bras de
l’utilisateur risqueraient d’être happés par l’accessoire
enmouvement.
k ) Ne jamais déposer l’outil électrique avant
l’immobilisation complète de l’accessoire.
L’accessoire en mouvement risquerait de mordre dans
la surface et de projeter l’outilélectrique.
l ) Mettre l’outil hors tension pour tout
déplacement de celui-ci par l’utilisateur. Un
contact accidentel avec l’accessoire en mouvement
pourrait happer les vêtements de l’opérateur et
projeter l’accessoire contre soncorps.
m ) Nettoyer régulièrement les évents de l’outil
électrique. Le ventilateur du moteur aspirera la
poussière à l’intérieur du boîtier. Une accumulation
excessive de poudre métallique représente un danger
d’origineélectrique.
n ) Ne pas faire fonctionner l’outil électrique à
proximité de matières inflammables. Les étincelles
produites risquent de lesenflammer.
o ) Ne pas utiliser d’accessoires qui exigent
l’utilisation d’un liquide de refroidissement.
L’utilisation d’eau ou de tout autre liquide
de refroidissement pourrait se solder par une
électrocution ou une secousseélectrique.
p ) Ne jamais utiliser de meules de type11 (boisseau
conique) sur cet outil. L’utilisation d’accessoires
inadéquats peut se solder par desblessures.
q ) Toujours se servir de la poignée latérale. La fixer
solidement. La poignée latérale doit être utilisée pour
maîtriser l’outil en touttemps.
r ) Au démarrage de l’outil avec une meule ou
une brosse métallique neuve, ou après l’avoir
changée, maintenir l’outil dans un espace
sécuritaire et le laisser tourner une minute. Si le
disque était affecté d’une fêlure ou d’un défaut caché,
il éclaterait en moins d’une minute. Si des fils de la
brosse métallique étaient lâches, cela serait alors
détecté. Ne jamais démarrer l’outil lorsque quelqu’un
se tient directement devant le disque, y compris
l’utilisateur.
s ) L’utilisation d’accessoires non spécifiés dans
ce manuel n’est pas recommandée et peut être
dangereuse. L’utilisation de compresseurs pour faire
fonctionner l’outil à une vitesse supérieure à sa vitesse
nominale estprohibée.
t ) Utiliser des serre-joints, ou tout autre moyen,
pour fixer et soutenir le matériau sur une surface
stable. Tenir la pièce à la main ou contre son corps
offre une stabilité insuffisante qui pourrait vous en
faire perdre lecontrôle.
u ) Protéger le disque contre tout choc ou traitement
brutal. Si c’était le cas, arrêter l’outil et vérifier que la
meule ne comporte ni fissures nidéfauts.
v ) Manipuler et stocker les meules en prenant
systématiquement desprécautions.
w ) Ne pas utiliser cet outil de façon prolongée. Les
vibrations inhérentes à l’utilisation de cet outil
posent des risques de dommages corporels
permanents aux doigts, mains et bras. Utiliser
des gants pour en atténuer l’impact, faire des pauses
fréquentes, et en limiter l’usagejournalier.
x ) Prendre des précautions à proximité des évents,
car ils cachent des pièces mobiles. Les vêtements
amples, bijoux ou cheveux longs pourraient s’y
faireprendre.
Causes de l’effet de rebond et prévention
par l’opérateur
L’effet de rebond est une réaction soudaine d’une meule,
d’un tampon, d’une brosse ou d’un tout autre accessoire, en
mouvement, qui est pincé ou qui s’accroche. Un pincement
ou un accrochage provoque un arrêt rapide de l’accessoire en
mouvement qui, à son tour, projette l’outil électrique, hors de
maîtrise, dans la direction opposée à la rotation de l’outil au
point degrippage.
Par exemple, si une meule abrasive se pince ou s’accroche
dans la pièce, le bord de la meule introduite au point de
pincement peut mordre dans la surface de la pièce et
projeter la meule hors de la rainure. La meule peut être
projetée vers l’opérateur ou dans la direction opposée selon
le sens de rotation de la meule au point de pincement. Il est
également possible que les meules abrasives se brisent dans
cesconditions.
Un effet de rebond est le résultat d’une mauvaise utilisation de
l’outil et/ou de procédures ou conditions de fonctionnement
incorrectes. Il peut être évité en prenant les précautions
nécessaires telles que décrites ci-dessous:
a ) Saisir fermement l’outil électrique et positionner
le corps et les bras de sorte à résister à la
force de l’effet de rebond. Utiliser toujours la
poignée auxiliaire, s’il y en a une, pour contrôler
au maximum l’effet de rebond ou le couple
de réaction au démarrage. Avec de bonnes
précautions, l’opérateur est en mesure de contrôler le
couple de réaction ou l’effet derebond.
b ) Ne jamais placer les mains près de l’accessoire en
mouvement. Il pourrait en effet être projeté sur celles-
ci en cas derebond.
FRANÇAIS
18
c ) Ne pas positionner le corps dans la trajectoire
probable de l’outil électrique, en cas de rebond.
Au moment du grippage, l’outil sera projeté dans la
direction opposée au déplacement de lameule.
d ) Être particulièrement attentif lors de travaux
dans un coin, sur des bords tranchants, etc.
Éviter de faire rebondir l’accessoire. Éviter tout
type de grippage de l’accessoire. Un travail dans
un coin ou sur des bords tranchants ou un travail en
faisant rebondir l’accessoire provoquent souvent un
grippage et une perte de maîtrise de l’outil ou un effet
derebond.
e ) Ne pas fixer de lame de tronçonneuse pour
sculpter le bois ou de lame de scie dentée. Ces
types de lames provoquent des effets de rebond et des
pertes de maîtrisefréquents.
Avertissements de sécurité spécifiques
aux opérations de meulage et de coupe
par abrasion
a ) Utiliser uniquement les types de meules
recommandés pour l’outil électrique ainsi que le
capot protecteur particulier conçu pour la meule
sélectionnée. Il est impossible de bien protéger
l’opérateur lors de l’utilisation de meules non conçues
pour l’outil. En effet, le capot protecteur sera alors
inadéquat et l’utilisation de la meule,dangereuse.
b ) La surface de meulage des meules à moyeu
déporté doit être posée sous la contre plaque
de la lèvre du carter. Le carter aide à protéger
l’utilisateur contre toute projection de fragments et
contre tout contact accidentel avec la meule ainsi qu’à
protéger les vêtements des étincelles qui pourraient
lesenflammer.
c ) Il faut fixer solidement le capot protecteur à
l’outil électrique et le positionner pour maximiser
la sécurité de l’opérateur, soit en minimisant
la surface exposée de la meule en direction
de l’opérateur. En effet, le capot protecteur sert à
protéger l’opérateur contre la projection de fragments
de meule brisée et de contact accidentel avec
celle-ci.
d ) Utiliser uniquement les meules pour les
applications prévues pour chacune d’entre elles.
Par exemple: ne pas meuler avec le bord d’une
meule tronçonneuse. Les meules tronçonneuses
par abrasion sont conçues pour travailler en
périphérie. L’application de forces latérales sur ces
meules risquerait de les faireéclater.
e ) Toujours utiliser des brides de meule intactes, de
la bonne dimension et de la forme appropriée
pour la meule sélectionnée. Les brides de meule
appropriées supportent bien la meule et réduisent
ainsi la possibilité d’un bris de meule. Les brides
conçues pour les meules tronçonneuses pourraient
différer des brides pour meules àponçage.
f ) Ne pas utiliser de meule usée en provenance
d’outil de dimension plus importante. Ces meules,
prévues pour un outil électrique plus grand, ne
conviennent pas au régime plus élevé d’un outil de
plus petite dimension et pourraientéclater.
Avertissements de sécurité
supplémentaires spécifiques aux
opérations de coupe par abrasion
a ) Ne pas «coincer» la meule tronçonneuse ou
ne pas appliquer une pression excessive. Ne
pas essayer de couper à une profondeur trop
importante. Une contrainte excessive sur la meule
accroîtra la charge et la possibilité de tordre ou
de gripper la meule dans le trait de coupe et ainsi
provoquer un effet de rebond ou un bris de lameule.
b ) Ne pas positionner le corps sur la trajectoire de la
meule en mouvement ni derrière celle-ci. Lorsque
la meule, au point de contact avec la pièce, s’éloigne
du corps de l’opérateur, un effet de rebond potentiel
risque de projeter la meule en rotation, ainsi que
l’outil, en direction de l’utilisateur.
c ) Lorsque la meule se grippe ou lors de l’arrêt
d’une coupe pour une raison quelconque, mettre
l’outil hors tension et maintenir l’outil immobile
jusqu’à l’arrêt complet de la meule. Ne jamais
essayer de retirer la meule tronçonneuse du
trait de coupe alors que celle-ci est encore en
mouvement. Une telle pratique risquerait de
provoquer un effet de rebond. Rechercher et
prendre l’action corrective nécessaire pour éliminer les
causes du grippage de lameule.
d ) Ne pas reprendre la coupe avec la meule dans
le trait de coupe de la pièce. Attendre que la
meule soit à plein régime puis la réinsérer
soigneusement dans le trait de coupe. Si l’outil
électrique redémarrait avec la meule appuyée sur la
pièce, celle-ci risquerait de gripper, de se déplacer ou
dereculer.
e ) Pour réduire le risque de pincement ou de recul
de la meule, soutenir les panneaux ou toute
autre pièce surdimensionnée. Les grandes pièces
tendent à s’affaisser sous leur propre poids.
Disposer des appuis sous la pièce, le long de la ligne
de coupe et près du bord de la pièce, des deuxcôtés
de lameule.
f ) Faire particulièrement attention lors de la
réalisation de «découpe en poche» dans des
murs existants ou d’autres zones sans visibilité.
La portion de la meule faisant saillie risque de couper
un tuyau d’alimentation en eau ou en gaz, des fils
électriques ou des objets pouvant provoquer un effet
derebond.
