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 a 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

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 ) Operations such as polishing are not
recommended to be performed with this
power tool. Operations for which the power tool
was not designed may create a hazard and cause
personalinjury.
c ) Do not convert this power tool to operate in a way
which is not specifically designed and specified by
the tool manufacturer. Such a conversion may result
in a loss of control and cause serious personalinjury.
d ) Do not use accessories which are not specifically
designed and specified by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safeoperation.
e ) 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.
f ) 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.
g ) 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.
h ) The dimensions of the accessory mounting must
fit the dimensions of the mounting hardware of
the power tool. Accessories that do not match the

Kickback and Related Warnings:
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 power 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 with both hands on the
power tool and position your body and arms
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 reactions 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,
segmented diamond wheel with a peripheral gap
greater than 10mm or toothed saw blade. Such
blades create frequent kickback and loss ofcontrol.
Safety Warnings Specific for Grinding and
Cutting‑Off Operations:
a ) Use only wheel types that are specified 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.
Damaged accessories will normally break apart during
this testtime.
j ) 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 applications. The dust mask or respirator must
be capable of filtrating particles generated by the
particular application. Prolonged exposure to high
intensity noise may cause hearingloss.
k ) 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.
l ) 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.
m ) 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.
n ) 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.
o ) 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.
p ) 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.
q ) Do not operate the power tool near flammable
materials. Sparks could ignite thesematerials.
r ) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution orshock.
s ) Do not use Type 11(flaring cup) wheels on this
tool. Using inappropriate accessories can result
ininjury.
t ) 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 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.
u ) 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.

ENGLISH
Safety Warnings Specific for Sanding
Operations:
a ) Use proper sized sanding disc paper. Follow
manufacturer'srecommendations, when
selecting sanding paper. Larger sanding paper
extending too far beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc orkickback.
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 specified 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 load and
centrifugalforces.
Additional Safety Warnings Specific for
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.
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 the wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold it 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 re‑enter 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.
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 specified
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. A wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
mayburst.
g ) When using dual purpose wheels always use
the correct guard for the application being
performed. Failure to use the correct guard may not
provide the desired level of guarding, which could lead
to seriousinjury.
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.
g ) Do not attempt to do curved cutting. 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, which can
lead to seriousinjury.
h ) When using diamond segmented wheels, always
use wheels with a maximum gap of 10 mm
between segments and a negative rake angle.
Additional Safety Information
WARNING: Never modify the power tool or any part of
it. Damage or personal injury couldresult.
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.

(15.2 m) of the use of thisproduct.
• 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

• Use the appropriate dust extractor vacuum to remove
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to
the operator and those in closeproximity.
• Use clamps or other practical ways to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and may
lead to loss ofcontrol andinjury.
• Always use auxiliary handle. Tighten the handle
securely. The auxiliary handle should always be used to
maintain control of the tool at alltimes.
• To prevent the spindle end from contacting the
bottom of the hole of the hubbed wheel, use
accessories that have a threaded hole depth of
at least 21mm. Failure to use an accessory with the
appropriate thread depth could result in damage to the
hubbed wheel and injury to the operator or persons in
thearea.
• The arbor size of hubbed wheels, flanges, backing
pads or any other accessory must properly fit the
spindle of the power tool. Accessories with arbor holes
that do not match the mounting hardware of the power
tool will run out of balance, vibrate excessively and may
cause loss ofcontrol.
• Avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the
wheel for cracks orflaws.
• Always handle and store wheels in a carefulmanner.

Damage to the tool will result and attached accessory
may spin off, possibly resulting ininjury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate the
spindlefurther.
NOTE: To reduce unexpected tool movement, do not switch
the tool ON or OFF while under load conditions. Allow the
grinder to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting itdown.
WARNING: Before connecting the tool to a power
supply, be sure the slider switch is in the OFF position
by pressing the rear part of the switch and releasing.
Ensure the slider switch is in the OFF position as
described above after any interruption in power supply
to the tool, such as the activation of a ground fault
interrupter, throwing of a circuit breaker, accidental
unplugging, or power failure. If the slider switch is
locked ON when the power is connected, the tool will
startunexpectedly.
To start the tool, slide the ON/OFF slider switch7 toward

Surface Grinding, Sanding and
WireBrushing
CAUTION:Always use the correct guard per the
instructions in thismanual.
NOTE: If the wheel spins after the clamp nut is tightened,
check the orientation of the threaded clamp nut. If a thin
wheel is installed with the pilot on the clamp nut against the
wheel, it will spin because the height of the pilot prevents
the clamp nut from holding thewheel.
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
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.
Slider Switch (Fig.A)
CAUTION: Hold the side handle and body of the tool
firmly to maintain control of the tool at start‑up and
during use and until the wheel or accessory stops
rotating. Make sure the wheel has come to a complete
stop before laying the tooldown.

ENGLISH

Edge Grinding and Cutting
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 1/2" (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 1/41wheel requires usage
of a Type 1/41guard.
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. 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.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
itdown.
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.
‑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 workpiece.
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 NIOSH‑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mm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
MAINTENANCE

qu’il fonctionne d’une manière qui n’est pas
spécifiquement conçue et spécifiée par le
fabricant de l’outil. Une telle conversion peut
entraîner une perte de contrôle et causer des
blessuresgraves.
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.
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.
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.

k) Gardez les passants à une distance sécuritaire
de l’aire de travail. Toute personne entrant dans
l’aire de travail doit porter un équipement de
protection individuel. Les fragments de la pièce à
travailler ou d’un accessoire brisé peuvent s’envoler
et peuvent causer une blessure au‑delà de l’aire
immédiate del’opération.
l) Tenez l’outil électrique seulement par les surfaces
de prise isolées lorsque vous effectuez une tâche
où l’accessoire de coupe peut entrer en contact
avec le câblage dissimulé ou son propre cordon.
L’accessoire de coupe entrant en contact avec un câble
«sous tension» peut mettre les pièces métalliques de
l’outil électrique «sous tension» et causer un choc
électrique àl’utilisateur.
m) Placez le cordon à l’écart de l’accessoire en
rotation. Si vous perdez le contrôle, le cordon peut être
coupé ou accroché et votre main ou votre bras peut
être tiré dans l’accessoire enrotation.
n) Ne jamais déposer l’outil électrique avant que
l’accessoire soit complètement arrêté. L’accessoire
en rotation peut accrocher la surface et vous faire
perdre le contrôle de votre outilélectrique.
o) Ne pas faire fonctionner l’outil électrique pendant
que vous le transportez à vos côtés. Un contact
accidentel avec l’accessoire en rotation pourrait
accrocher vos vêtements, tirant l’accessoire dans
votrecorps.
p ) Nettoyez régulièrement les évents de l’outil
électrique.Le ventilateur du moteur produit de la
poussière à l’intérieur du boîtier et l’accumulation
excessive de métal fritté peut causer des
chocsélectriques.
q) Ne pas utiliser l’outil électrique près de matières
inflammables. Des étincelles pourraient enflammer
cesmatières.
r ) Ne pas utiliser des accessoires qui nécessitent des
liquides réfrigérants. Utiliser de l’eau ou d’autres
liquides réfrigérants peut entraîner une électrocution
ou un chocélectrique.
s ) Ne pas utiliser les meules de type 11(soucoupe)
sur cet outil. L’utilisation d’accessoire inadaptés peut
provoquer desblessures.
t ) Avant de démarrer l’outil avec une nouvelle meule
installée ou d’un remplacement de la brosse
métallique installée, tenez l’outil dans un endroit
bien protégé et laissez‑le fonctionner durant une
minute. Si la meule a une fissure ou un défaut
non détecté, elle devrait éclater en moins d’une
minute. Si la brosse métallique a des fils desserrés,
ils seront détectés. Ne jamais démarrer l’outil
avec une personne en ligne avec le disque. Cela
comprendl’utilisateur.
u ) L’utilisation d’accessoires non spécifiés dans ce
manuel est déconseillée et peut être dangereuse.
L’utilisation d’amplificateurs de puissance pour faire
tourner l’outil à des vitesses supérieures à sa vitesse
nominale constitue un mauvaisemploi.
d) Ne pas utiliser des accessoires qui n’ont pas été
spécifiquement conçus et recommandés par le
fabricant de l’outil.Le fait que l’accessoire peut être
fixé à votre outil n’assure pas une utilisationsécuritaire.
e) La vitesse nominale de l’accessoire doit être au
moins égale à la vitesse maximale indiquée sur
l’outil électrique. Les accessoires qui fonctionnent
plus rapidement que leur vitesse nominale peuvent se
briser et voler enéclats.
f) Le diamètre extérieur et l’épaisseur de votre
accessoire doivent être conformes à la capacité
nominale de votre outil. Les accessoires de format
incorrect ne peuvent pas être protégés ou contrôlés de
façonappropriée.
g ) Le montage fileté des accessoires doit
correspondre au filet de tige de la meuleuse.
Pour les accessoires fixés par des brides, l’alésage
central de l’accessoire doit correspondre au
diamètre de repérage de la bride. Les accessoires
qui ne correspondent pas au matériel de montage de
l’outil électrique manqueront d’équilibre, vibreront
de façon excessive ou peuvent entraîner une perte
decontrôle.
h ) Les dimensions de la fixation de l’accessoire
doivent correspondre aux dimensions du matériel
de fixation de l’outil électrique. Les accessoires qui
ne correspondent pas au matériel de montage de l’outil
électrique manqueront d’équilibre, vibreront de façon
excessive ou peuvent entraîner une perte decontrôle.
i ) Ne pas utiliser un accessoire endommagé. Avant
chaque utilisation, inspectez les accessoires
comme les disques abrasifs en termes de copeaux
et de fissures, la plaque d’appui en termes de
fissures, de déchirure ou d’usure excessive, la
brosse métallique en termes de fils détachés ou
cassés. Si vous échappez l’outil ou un accessoire,
inspectez‑le pour des dommages ou installez un
accessoire non endommagé. Après avoir inspecté
et installé un accessoire, placez‑vous ainsi que
les passants à distance de la zone de rotation de
l’accessoire et faites fonctionner l’outil électrique
à une vitesse à vide pendant une minute. Les
accessoires endommagés se brisent normalement
durant la durée dutest.
j ) Portez un équipement de protection individuelle.
Selon l’application, utilisez un masque de
protection ou des lunettes de sécurité. Selon
les besoins, portez un masque anti‑poussière,
une protection auditive, des gants et un tablier
d’atelier pouvant arrêter de petits fragments
de la pièce de travail ou abrasifs. La protection
des yeuxdoit être en mesure d’arrêter les débris
volants générés par diverses applications. Le masque
anti‑poussière ou le respirateur doit être en mesure
de filtrer les particules générées par l’application
concernée. L’exposition prolongée à du bruit d’intensité
élevée peut causer une perteauditive.

Avertissements supplémentaires de
sécurité spécifiques pour les opérations de
meulage et de coupe:
a ) Ne pas «bloquer» la meule de coupe ou appliquer
une pression excessive. Ne tentez pas de faire une
coupe de profondeur excessive. Surcharger la meule
augmente la charge et la prédisposition à la torsion ou
au coinçage de la meule dans la coupe et la possibilité
de rebond ou de bris de lameule.
b ) Ne pas placer votre corps en ligne avec et derrière
la meule en rotation. Lorsque la meule, au point
de fonctionnement, se déplace loin de votre corps, le
possible rebond peut projeter la meule en rotation et
l’outil électrique directement survous.
c ) Lorsque la meule se bloque ou lorsque vous
interrompez une coupe pour une raison
quelconque, arrêtez l’outil électrique et
maintenez‑le immobile jusqu’à ce que la meule
s’arrête complètement. Ne jamais tenter de retirer
la meule de coupe de la coupe pendant que la
meule est en mouvement sinon un rebond peut
se produire. Examinez‑la et prenez des mesures
bord du protecteur. Une meule mal installée qui
projette à travers le rabot de la lèvre de la protection ne
peut pas bien êtreprotégée.
c ) La protection doit être fixée de façon sécuritaire
à l’outil électrique et placée pour une sécurité
maximale afin que le moins de la meule possible
soit exposé à l’utilisateur. La protection aide à
protéger l’utilisateur des fragments de la meule brisée,
du contact accidentel avec la meule et des étincelles
qui pourraient enflammer vosvêtements.
d ) Les meules doivent être utilisées seulement
pour les applications spécifiées. Par exemple:
ne pas meuler avec le côté de la meule de coupe.
Les meules de coupe sont conçues pour le meulage
périphérique, les forces latérales appliquées sur ces
meules peuvent les faireéclater.
e ) Utilisez toujours des brides de meules non
endommagées ayant la bonne taille et la bonne
forme pour la meule sélectionnée. Les brides de
meules appropriées soutiennent la meule réduisant
ainsi la possibilité d’un bris de la meule. Les brides pour
les meules de coupe peuvent être différentes des brides
de meules demeulage.
f ) Ne pas utiliser des meules usées d’outils
électriques plus gros.La meule conçue pour les outils
électriques plus gros ne convient pas pour la vitesse
plus élevée d’un petit outil et peutéclater.
g ) Lorsque vous utilisez des meules à double usage,
utilisez toujours le protecteur approprié pour
l’application en cours. Si vous n’utilisez pas la
protection appropriée, vous risquez de ne pas obtenir le
niveau de protection souhaité, ce qui pourrait entraîner
des blessuresgraves.
Avertissements de sécurité spécifiques
pour les opérations de meulage et
decoupe:
a ) Utilisez seulement les meules spécifiées pour
votre outil électrique et la protection conçue
pour la meule sélectionnée. Les meules qui ne sont
pas conçues pour l’outil électrique ne peuvent être
protégées convenablement et ne sont passécuritaires.
b ) La surface de meulage des meules à moyeu
déporté doit être installée dessous le rabot du
Rebond et avertissements associés:
Le rebond est une réaction soudaine d’une meule, d’un
tampon, d’une brosse ou tout autre accessoire en rotation
coincée ou accrochée. Le coinçage ou l’accrochage entraîne
un blocage rapide de l’accessoire en rotation qui à son tour
fait en sorte que l’outil électrique non contrôlé soit forcé dans
la direction opposée de la rotation de l’accessoire au point
depincement.
Par exemple, si une meule abrasive est accrochée ou coincée
dans la pièce de travail, le bord de la meule qui est entré
dans le point de coincement peut creuser la surface du
matériau causant la chute ou l’éjection de la meule. La meule
peut bondir vers ou loin de l’utilisateur, selon la direction du
mouvement de la meule au point de pincement. Les meules
abrasives peuvent aussi se briser dans cesconditions.
Le rebond est le résultat d’une mauvaise utilisation de
l’outil électrique et/ou de procédures ou de conditions de
fonctionnement incorrectes et il peut être évité en prenant
les précautions appropriées définies ci‑dessous :
a ) Maintenez une prise ferme des deux mains sur
l’outil électrique et positionnez votre corps et vos
bras de manière à pouvoir résister aux forces de
rebond. Utilisez la poignée auxiliaire, si fournie,
pour un contrôle maximum sur le rebond ou
la réaction de couple durant le démarrage.
L’utilisateur peut contrôler les forces du rebond ou
la réaction de couple si les précautions appropriées
sontprises.
b ) Ne jamais placer votre main près de l’accessoire
en rotation. L’accessoire peut rebondir sur votremain.
c ) Ne pas placer votre corps dans la zone où l’outil
électrique se déplacera si un rebond se produit. Un
rebond projettera l’outil dans la direction opposée du
mouvement de la meule au pointd’accrochage.
d ) Faites attention lorsque vous travaillez dans
les coins, les bords coupants, etc. Évitez le
rebondissement ou l’accrochage de l’accessoire.
Les coins, les bords coupants ou le rebondissement ont
tendance à accrocher l’accessoire en rotation et causer
une perte de contrôle ou unrebond.
e ) Ne pas fixer une scie à chaîne, une lame de
sculpture de bois, une meule diamantée
segmentée ayant un espace périphérique plus
grand que 10mm ou une lame de scie dentée. Ces
lames créent fréquemment des rebonds et une perte de
la maîtrise del’outil.
