General Safety Rules -For All Tools
_WARNING! Read and understand all instructions.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
•Keep your work area clean and well lit. Cluttered benches
and dark areas invite accidents.
•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.
• Keep bystanders, children, and visitors away while operat-
ing a power tool Distractions can cause you to lose control
ELECTRICAL SAFETY
• Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adaptor plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded, ff the tools should electrical-
ly malfunction or break down, grounding provides a low resist-
ance path to carry electricity away from the user. Applicable
only to Class I (grounded) tools.
• Double insulated tools are equipped with a polarized plug
(one blade is wider than the other.) This plug will fit in a
polarized outlet only one way. ff the plug does not fit fully in
the outlet, reverse the plug. ff it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation [] eliminates
the need for the three wire grounded power cord and grounded
power supply system. Applicable only to Class II (double
insulated) tools.
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk
of electric shock ffyour body is grounded.
Don't expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools
or pull the plug from an outlet. Keep cord away from heat,
oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor
extension cord marked "'W-A" or "'W." These cords are rated
for outdoor use and reduce the risk of electric shock. When
using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and over-
heating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating, ff in
doubt, use the next heavier gage. The smaller the gage number,
the heavier the cord.

PERSONAL SAFETY
• Stay alert, watch what you are doing and use common
sense when operating a power tool Do not use tool while
tired or under the influence of drugs, alcohol, or medica-
tion. A moment of inattention while operating power tools may
result in serious personal injurjz.
• Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves away
from moving parts. Loose clothing, jewelrj4 or long hair can be
caught in moving parts. Air vents often cover moving parts and
should also be avoided.
•Avoid accidental starting. Be sure switch is off before plug-
ging in. Carrying tools with your finger on the switch or plugging
in tools that have the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool
on. A wrench or a key that is left attached to a rotating part of
the tool may result in personal injury
•Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control of the
tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
TOOL USE AND CARE
•Use clamps or other practical way 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.
•Do not force tool Use the correct tool for your application.
The correct tool will do the job better and safer at the rate for
which #is designed.
• Do not use tool ff switch does not turn #on or off. Any tool
that cannot be controlled with the switch is dangerous and must
be repaired.
•Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tooL
Such preventative safety measures reduce the risk of starting
the tool accidentally.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools, with sharp cutting edges are
less likely to bind and are easier to control
• Check for misalignment or binding of moving parts, break-
age of parts, and any other condition that may affect the
tool's operation, ff damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manu-
facturer for your model Accessories that may be suitable for
one tool may become hazardous when used on another tool
SERVICE
• Tool service must be performed only by qualified repair
personneL Service or maintenance performed by unqualified
personnel could result in a risk of injury
• When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this man-
ual Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of electric shock or injury.
Additional Specific Safety Instructions
for Grinders
•Check that the grinding wheel backing flange has a yellow
rubber ring (S) installed, see Figure 1. Replace rubber ring ff
missing, damaged or worn. See page 9 for details regarding
proper accessory installation.
_WARNING: The grinding wheel or accessory may loosen
during coast-down of the tool when shut off if rubber ring is

missingordamaged,ff grinding wheel or accessory loosens, #
may dismount from the machine and may cause serious personal
injury
•Always use proper guard with grinding wheel A guard pro-
tects operator from broken wheel fragments and wheel contact.
•Accessories must be rated for at least the speed recom-
mended on the tool warning label Wheels and other acces-
sories running over rated speed can fly apart and cause injury.
Accessory ratings must be above listed minimum wheel speed
as shown on tool nameplate.
•Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring or its own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and shock the operator.
•Do not use Type 11 (flaring cup) wheels on this tooL Using
inappropriate accessories can result in injury.
•ALWAYS WEAR EYE PROTECTION WHEN USING THIS
TOOL.
•Use of accessories not specified in this manual is not rec-
ommended 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.
• Do not use circular saw blades or any other toothed blades
with this tool Serious injury may result.
•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, ff the
wheel has an undetected crack or flaw, it should burst in less
than one minute, ff 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.
• Avoid bouncing the wheel or giving it rough treatment, ff this
occurs, stop the tool and inspect the wheel for cracks or flaws.
• Direct sparks away from operator, bystanders or flammable
materials. Sparks may be produced while cutting and/or
grinding. Sparks may cause bums or start fires.
• Always use side handle. Tighten the handle securely. The
side handle should always be used to maintain control of the tool
at all times.
•Never cut into area that may contain electrical wiring or
piping. Serious injury may result.
• Clean out your tool often, especially after heavy use. Dust
and grit containing metal particles often accumulate on interior
surfaces and could create an electric shock hazard.
• 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.
•Direct the Dust Ejection System (DES) away from operator
and coworkers. Serious injury may result (Fig. 1, K).
•The label on your tool may include the following symbols. The
symbols and their definitions are as follows:
V.......... volts

.../min ....revolutions per minute
Causes and Operator Prevention
of Kickback
•Kickback is a sudden reaction to apinched, bound or misaligned
wheel, wire brush or flap disc causing an uncontrolled cut-off
tool to lift up and out of the workpiece toward the operator.

•When the wheel is pinched or bound tightly by the workpiece,
the wheel stalls and the motor reaction drives the un# rapidly
back toward or away from the operator.
• 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:
•Maintain a firm grip with both hands on the un#andposi-
tion your body and arm to allow you to resist kickback
forces. Kickback forces can be controlled by the operator, if
proper precautions are taken.
• When wheel is binding, or when interrupting a cut for any
reason, release the trigger and hold the unit motionless
in the material until the wheel comes to a complete stop.
Never attempt to remove the unit from the work or pull
the unit backward while the wheel is in motion or kick-
back may occur. Investigate and take corrective actions to
eliminate the cause of wheel binding.
• When restarting a cut-off tool in the workpiece, check
that the wheel is not engaged into the material ff wheel is
binding, it may walk up or kickback from the workpiece as the
tool is restarted.
•Support large panels to minimize the risk of wheel pinch-
ing and kickback. Large panels tend to sag under their own
weight. Support must be placed under the panel on both
sides, near the line of cut and near the edge of the panel
AWARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chem-
icals known 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 (CCA).
Your risk from these exposures varies, depending on how often
you do this type of work. Toreduce your exposure to these chem-
icals: work in a well ventilated area, and work with approved safe-
ty 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 disburse dust,
which may cause serious and permanent respiratory or other injury
Always use NIOSH/OSHA approved respiratory protection appro-
priate for the dust exposure. Direct particles away from face and
body
_, CAUTION: Use extra care when working into a comer because
a sudden, sharp movement of the grinder may be experienced
when the wheel or other accessory contacts a secondary surface
or a surface edge.
_CAUTION: Wear appropriate personal hearing protection
during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.

is available in various grits. Coarse grits yield faster material
removal rates and a rougher finish. Finer grits yield slower
material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal.
Move to a medium grit paper and finish with a fine grit disc for
optimal finish.
Coarse 16 - 30 grit
Medium 36 - 80 grit
Fine Finishing 100 - 120 grit
Very Fine Finishing 150 - 180 grit
1. Allow the tool to reach full speed before touching tool to the

the tool and work surface. The san-
ding disc should contact approxi-
mately one inch of work surface.
4. Move the tool constantly in a straight 5°-15°
line to prevent burning and swirling
of work surface. Allowing the tool to rest on the work surface
without moving, or moving the tool in a circular motion causes
burning and swirling marks on the work surface.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. Use only wire brushes or
wheels provided with a 5/8"-11 threaded hub. AType 27 guard is
required when using wire brushes and wheels.
_CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
CAUTION: Wheel or brush must not touch guard when mounted
or while in use. Undetectable damage could occur to the accessory,
causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
i& CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or acces-
sories. Before reconnecting the tool, turn the switch on and off
as previously described to ensure that the tool is off.
1. Thread the wheel on the spindle by hand.
2. Depress spindle lock button and use a wrench on the hub of the
wire wheel or brush to tighten the wheel.
3. To remove the wheel, reverse the above procedure.
i_,CAUTION: Failure to properly seat the wheel hub before turning
the tool on may result in damage to tool or wheel
USING WIRE CUP BRUSHES AND WIRE WHEELS
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to work surface, allowing the tool to
operate at high speed. Material removal rate is greatest when
the tool operates at high speed.
3. Maintain a 5° to 10° angle between the
tool and work surface for wire cup
brushes.
4. Maintain contact between the edge of
the wheel and the work surface with
wire wheels.
5. Continuously move the tool in a forward
and back motion to avoid creating gouges in
the work surface. Allowing the tool to rest on
the work surface without moving, or moving
the tool in a circular motion causes burning
and swirling marks on the work surface.
6. Remove the tool from the work surface before turning the tool
off. Allow the tool to stop rotating before setting it down.
_CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.

Mounting and Using Cutting
(Type 1) Wheels
Cutting wheels include diamond wheels and abrasive discs.
Abrasive cutting wheels for metal and concrete use are available.
Diamond blades for concrete cutting can also be used.
_WARNING: A closed, 2-sided cutting wheel guard is not included
with this tool but is required when using cutting wheels. Failure to
use proper flange and guard can result in injury resulting from wheel
breakage and wheel contact. See page 7 for more information.
MOUNTING CLOSED (TYPE 1) GUARD
_, CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or acces-
sories. Before reconnecting the tool, turn the switch on and off
as previously described to ensure that the tool is off.
1. Open the guard latch (M). Align O
the lugs (N) on the guard with the
slots (O) on the gear case.
2. Push the guard down until the
guard lug engages and rotates
freely in the groove on the gear
case hub.
3. Rotate guard (I) into desired M
working position. The guard body
should be positioned between the
spindle and the operator to provide
maximum operator protection.
4. Close the guard latch to secure the guard
on the gear case cover. You should be
unable to rotate the guard by hand when
the latch is in closed position. If rotation is I
possible, tighten the adjusting screw (P) with clamp lever in the
closed position. Do not operate grinder with a loose guard or
clamp lever in open position.
5. To remove the guard, open the guard latch, rotate the guard so
that the arrows are aligned and pull up on the guard.
NOTE: If, after a period of time, the guard
becomes loose, tighten the adjusting
screw (P) with the clamp lever in the
closed position.
i_CAUTION: Do not tighten adjusting
screw with clamp lever in open position.
Undetectable damage to guard or
mounting hub may result.
MOUNTING CUTTING WHEELS
CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or acces-
sories. Before reconnecting the tool, turn the switch on and off
as previously described to ensure that the tool is off.
_,CAUTION: Matching diameter threaded backing flange and
clamp nut (included with tool) must be used for cutting wheels.
1. Place the unthreaded backing flange on spindle with the raised
section (pilot) facing up. The raised section (pilot) on the back-
ing flange will be against the wheel when the wheel is installed.
2. Place the wheel on the backing flange, centering the wheel on
the raised section (pilot).
3. Install the threaded clamp nut with the raised section (pilot)
facing away from the wheel.
4. Depress the spindle lock button and tighten clamp nut with
a wrench.
5. To remove the wheel, grasp and turn while depressing the
spindle lock button.
13

USING CUTTING WHEELS
WARNING: Do not use edge grinding/
cutting wheels for surface grinding applica-
tions because these wheels are not
designed for side pressures encountered
with surface grinding. Wheel breakage and
injury may result.
1. Allow tool to reach full speed before
touching tool to work surface.
2. Apply minimum pressure to work
surface, allowing tool to operate at
high speed. Cutting rate is greatest [
when the tool operates at high speed.
3. Once a cut is begun and a notch is established in the work-
piece, do not change the angle of the cut. Changing the angle
will cause the wheel to bend and may cause wheel breakage.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
MAINTENANCE
Cleaning
AWARNING: Blowing dust and grit out of motor and switch actuator
using clean, dry compressed air is a necessary regular maintenance
procedure. Dust and grit containing metal particles often accumulate

R_gles de s_curit_ -G_n_ralit_s
_AVERTISSEMENT : Lire, comprendre et suivre
toutes les directives pr_cis_es ci-dessous, y com-
pris les consignes de securite, afin d'eviter les risques de
choc electrique, d'incendie ou de blessure grave.
CONSERVER CES DIRECTIVES
AIRE DE TRAVAIL
• L'aire de travail doff 6tre propre et bien eclairee. Les 6tablis
encombr6s et les endroits sombres peuvent entrafner des acci-
dents.
•Ne pas faire fonctionner des outils electriques clans des
atmospheres explosives, comme en presence de liquides,
de gaz et de poussieres inflammables. Les outi/s 6/ectriques
produisent des 6tincelles qui peuvent enflammer la poussiere
ou les vapeurs
•Tenir les enfants, les visiteurs ou toute autre personne
I'ecart Iorsqu'on utilise un outil electrique; les distractions
peuvent faire perdre la mMtrise de ce demier.
MESURES DE SI_CURITI_ - I_LECTRICITI_
•Les outils mis a la terre doivent 6tre branches clans une
prise correctement instailee et raise a la terre tel que
I'indiquent les codes et reglements en vigueur. Ne jamais
retirer la broche de raise a la terre ou modifier la prise en
aucune faFon. Ne pas utiliser de fiche d'adaptation.
Consulter un electricien qualifie s'il y aun doute en ce qui
concerne la mise ala terre de la prise. En cas de d6fai//ance
61ectrique ou de bris de I'outil, la mise a la terre procure un
chemin de faible r6sistance au courant afin de r6duire les
risques de choc 61ectrique. Cette protection ne s'applique
qu'aux outils de classe I (mis a la terre).
• Les outils a double isolation sont munis d'une fiche polar-
isee (c'est&-dire que I'une des lames est plus large que
I'autre), laqueile ne peut 6tre raccordee qu'a une prise
polarisee et ce, clans un seul sens; on dolt I'inverser si on
est incapable de I'enfoncer completement. Si la fiche ne
s'adapte toujours pas, on dolt faire appel a un electricien
qualifie pour qu'il installe la prise appropriee. On ne doit
jamais modifier la fiche. La double isolation [] 61imine
le besoin d'installer un cordon d'alimentation trifilaire et un
systeme d'alimentation 61ectrique pourvus d'une mise a la terre;
seuls les outils de classe II (a double isolation) sont munis
d'une telle protection.
• Eviter tout contact entre le corps et les elements mis a la
terre, comme les tuyaux, les radiateurs, les cuisinieres et
les refrigerateurs, afin de r6duire les risques de choc
61ectrique.
• Ne pas utiliser I'outil electrique clans des endroits mouilles,
ni I'exposer a la pluie; I'infiltration d'eau a I'int6rieur de I'outil
augmente les risques de choc 61ectrique.
• Ne pas utiliser le cordon de maniere abusive; on ne doitpas
transporter I'outil en le tenant par le cordon, ou utiliser ce
dernier pour le debrancher. On doit tenir le cordon a I'ecart
des sources de chaleur, de I'huile, des bords tranchants
ou des pieces mobiles. Remplacer immediatement les
cordons endommages, car ces demiers augmentent les
risques de choc #lectrique.
• Lorsqu'on utilise un outil electrique a I'exterieur, on ne dolt
utiliser que des railonges conFues pour cet usage, comme
ceiles de type ,, W-A ,, ou , W ,,, afin de r#duire les risques de
choc #lectrique. S'assurer que la rallonge est en mesure de
porter le courant n#cessaire a I'outil. Une rallonge de calibre
16

inf6rieur entraTnera une chute de tension se traduisant par une
perte de puissance et une surchauffe. Le tableau ci-dessous
illustre les calibres que I'on dolt utiliser scion la Iongueur de la
rallonge et I'intensit6 nominale indiqu6e sur la plaque signal6-
tique. En cas de doute, utiliser le calibre suivant. Plus le calibre
est petit, plus la rallonge peut porter du courant.

SI_CURITI_ PERSONNELLE
*Rester vigilant en tout temps et faire preuve de jugement
Iorsqu'on utilise un outil electrique. Ne pas utiliser I'outil
Iorsqu'on est fatigue ou sous I'influence de drogues,
d'alcool ou de medicaments, car un moment d'inattention
pourrait entrMner des blessures graves.
,Porter des v6tements appropries. Ne pas porter des v6te-
ments amples ou des bijoux. Couvrir ou attacher les
cheveux longs. Garder les cheveux, les v6tements, les
bijoux et les gants eloignes des pieces mobiles, car ceux-ci
peuvent s'y coincer. Se tenir 61oign6 des 6vents puisque ces
demiers pourraient camoufler des pieces mobiles.
.Eviter les demarrages accidentels; s'assurer que I'interrup-
teur est en position d'arr6t avant de brancher I'outil. Ne pas
transporter I'outil en laissant le doigt sur I'interrupteur nile
brancher Iorsque I'interrupteur est en position de marche, car
cela pourrait causer un accident.
•Retirer les cles de reglage avant de demarrer I'outil. Une cl6
laiss6e sur une piece rotative pourrait entraTner des blessures.
°Ne pas trop etendre les bras. Les pieds doivent rester
ancres fermement au sol afin de maintenir son equilibre en
tout temps et de mieux maTtriser I'outil dans des situations
impr6vues.
•Utiliser le materiel de securite approprie; toujours porter
des lunettes de protection. Porter un masque anti-poussieres,
des chaussures antid6rapantes, un casque de s6curit6 ou des
protecteurs auditifs Iorsque la situation le requiert.
UTILISATION ET ENTRETIEN DE L'OUTIL
•Fixer et soutenir la piece sur une plate-forme stable au
moyen d'une bride de serrage ou de tout autre dispositif
semblable. La piece est instable Iorsqu'on la retient
manuellement ou qu'on I'appuie contre le corps, ce qui pourra#
faire perdre la maftrise de Ibutil.
•Ne pas forcer I'outil ni I'utiliser pour des travaux autres que
ceux pour lesquels il a ete con_u. Pour obtenir de meilleurs
r6sultats et pr6venir les risques de blessure, laisser Ibutil
couper a la vitesse pour laquelle il a 6t6 congu.
•Ne pas utiliser I'outil Iorsque I'interrupteur marche-arr6t ne
fonctionne pas. Tout outil qui ne peut 6tre command6 au
moyen de I'interrupteur est dangereux et doit 6tre r6par6.
•Debrancher I'outil de la source d'alimentation electrique
avant d'effectuer un reglage, de changer les accessoires ou
de ranger I'outil; ces mesures de s6curit6 pr6ventives
r6duisent les risques de d6marrage accidentel.
• Lorsqu'on n'utilise pas I'outil, le ranger hors de la portee
des enfants ou des personnes non qualifiees. Les outils sont
dangereux entre les mains de personnes inexp6riment6es.
• Bien entretenir I'outil; s'assurer qu'il est toujours bien
propre et aiguise. Les outils bien entretenus et dont les bords
sont bien tranchants sont moins susceptibles de rester coinc6s
et sont plus faciles a maftriser.
17

• Verifier les pieces mobiles afin de s'assurer qu'elles sont
bien alignees et qu'elles ne restent pas coincees. Verifier
egalement les pieces afin de s'assurer qu'il n'y a aucun
bris ni aucune autre condition susceptible de nuire au bon
fonctionnement de I'outil. Faire reparer I'outil si ce dernier
est endommage avant de s'en servir anouveau, car/es
accidents sont souvent caus6s par des outils mal entretenus.
•N'utiliser que les accessoires recommandes par le fabricant
pour le modele concerne. Un accessoire destin6 a un outi/
particulier peut devenir dangereux Iorsqu'il est utilis6 avec un
autre.
ENTRETIEN
•L'outil doit 6tre entretenu par le personnel qualifie seule-
ment; toute maintenance effectu6e par une personne non
qualifi6e pourrait entrMner des risques de blessure.
• Lors de I'entretien, n'utiliser que des pieces de rechange
identiques et suivre les directives precisees a la section
, Entretien ,, du present guide afin de pr6venir les risques de
choc 61ectrique ou de blessure.
Directives de s_curit_ suppl_mentaires
pour meuleuses
• S'assurer que la bride tournante sur collet battu de la meule est
dot6e d'une rondelle (S) en caoutchouc jaune (Fig. 1).
Remplacer la rondelle si elle est manquante, endommag6e ou
us6e. Se reporter a la page 26 pour obtenir de I'information
d6taill6e sur I'installation de I'accessoire appropri6.
_AVERTISSEMENT : La meule ou I'accessoire peut se desser-
rer durant le ralentissement de I'outil mis aI'arr_t si la rondelle
de caoutchouc est manquante ou endommagee. Si /ameu/e ou
I'accessoire se desserre, I'un ou I'autre peut sortir de la machine et
causer des blessures graves.
•Toujours utiliser un dispositif de protection adequat avec
une meule. Le dispositif de protection protege I'op6rateur con-
tre les fragments de meule et emp6che tout contact avec la
meule.
• Les accessoires doivent 6tre classes au moins pour la
vitesse recommandee indiquee sur I'etiquette d'avertisse-
ment de I'outil. Les meules et tout autre accessoire fonction-
nant a une vitesse sup6rieure a la vitesse nominale risquent
d'etre projet6s et de causer des blessures. Les caract6ristiques
nominales des accessoires doivent #tre sup6rieures a la vitesse
minimale indiqu6e sur la plaque signal6tique de I'outil.
• Tenez I'outil par sa surface de prise isolee clans une situa-
tion oO I'outil de coupe peut entrer en contact avec un
c#blage cache ou avec son propre cordon d'alimentation.
Tout contact avec un fil , sous tension _,mettra _,sous tension _,
les pieces m6talliques de I'outil et I'op6rateur recevra une
d6charge 61ectrique.
• Ne pas utiliser les meules de type 11(boisseau conique) sur
cet outil. A!epas utiliser les bons accessoires peut entraTner des
blessures.
• TOUJOURS PORTER UNE PROTECTION OCULAIRE POUR
UTILISER CET OUTIL.
•II n'est pas recommande d'utiliser des accessoires non
indiques clans le present mode d'emploi; cela peut 6tre
dangereux. Utiliser des amplificateurs de puissance qui
feraient fonctionner I'outil a une vitesse sup6rieure a sa
vitesse nominale repr6sente une utilisation abusive.
•Ne pas utiliser de lames de scies circulaires ou toute autre
lame dentee avec cet outil. II peut en r6sulter des blessures
graves.
• Au demarrage de I'outil, pourvu d'une meule neuve ou de
rechange ou d'une brosse metallique neuve ou de
rechange, le tenir clans un endroit bien protege et le laisser
18

tourner pendant une minute. Si la meule pr6sente une fissure
ou un d6faut non d6tect6, elle 6clatera en moins d'une minute.
Si la brosse m6tallique pr6sente des broches m6talliques mal
fix6es, les broches seront d6tect6es. Ne jamais d6marrer I'outil
si une personne se trouve dans la trajectoire de la meule, y
compris I'op6rateur.
•Eviter de faire rebondir la meule ou de la traiter durement.
Si cela se produit, arr6ter I'outil et inspecter la meule a la
recherche de fissures ou de d6fauts.
•Diriger les etincelles loin de I'operateur, des personnes
presentes et de toute matiere inflammable. Des 6tince//es
peuvent se produire durant la coupe ou le meulage. Les 6tin-
celles peuvent causer des brDlures ou provoquer un incendie.
• Toujours utiliser la poignee laterale. Serrer solidement la
poign6e. La poign6e lat6rale doit toujours _tre utilis6e afin de
garder la maitrise de I'outil en tout temps.
•Ne jamais couper aun endroit pouvant contenir un c_blage
electrique ou des tuyaux. //peut en resu/ter des b/essures
graves.
• Nettoyer souvent I'outil, surtout apres un usage intensif. La
poussiere et la salet6 contenant des particules m6talliques s'ac-
cumulent souvent sur les surfaces internes et peuvent pr6sen-
ter un risque de choc 61ectrique.
• Ne pas faire fonctionner cet outil durant de Iongues peri-
odes. Les vibrations caus6es par le fonctionnement de I'outil
peuvent provoquer des blessures permanentes aux doigts, aux
mains et aux bras. Utiliser des gants afin d'amortir davantage les
vibrations, s'arr6ter fr6quemment et limiter I'utilisation quotidi-
enne de I'outiL
• Diriger le dispositif d'evacuation des poussieres loin de
I'operateur et des collegues. II peut en r6sulter des blessures
graves (fig. 1, K).
•L'6tiquette appos6e sur I'outil peut afficher les symboles
suivants. Ces symboles et leurs d6finitions sont les suivants :

Causes de I'effet de rebond et
prevention de I'op_rateur
•L'effet de rebond est la r6action soudaine d'une meule, d'une
brosse m6tallique ou d'un disque a lamelle pinc6, coinc6 ou mal
align6, c'est-a-dire une perte de maitrise de Ibutil de trongon-
nage qui est soulev6 hors de la piece, vers I'op6rateur.
•Lorsque la meule est pinc6e ou tres coinc6e par la piece, la
meule bloque et le moteur r6ag# en entra_nant rapidement la
meule vers I'op6rateur ou loin de ce demier.
•L'effet de rebond r6sulte d'une utilisation abusive de Ibutil et/ou
de mauvaises proc6dures d'utilisation ou conditions. Cela peut
6tre 6vit6 par la prise de pr6cautions ad6quates comme celles
indiqu6es ci-apres :
•Tenir fermement I'outil a deux mains, puis positionner le
corps et les bras de maniere aresister aux forces de
I'effet de rebond. Les forces de I'effet de rebond peuvent
6tre maitris6es par I'op6rateur si les pr6cautions ad6quates
sont prises.
•Si la meule se coince ou si la coupe est interrompue
pour quelque raison que ce soit, rel&cher la g&chette et
tenir I'outil immobile clans le materiau jusqu'a ce que la
meule s'arr6te completement. Ne jamais tenter d'enlever
I'outil de la piece ou de tirer sur I'outil Iorsque la meule
