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

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

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) Battery Tool Use and Care

a ) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type

of battery pack may create a risk of fire when used

with another batterypack.

b ) Use power tools only with specifically designated

battery packs. Use of any other battery packs may

create a risk of injury andfire.

c ) When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins,

keys, nails, screws or other small metal objects,

that can make a connection from one terminal to

another. Shorting the battery terminals together may

cause burns or afire.

d ) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact

accidentally occurs, flush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation

orburns.

e ) Do not use a battery pack or tool that is

damaged or modified. Damaged or modified

batteries may exhibit unpredictable behavior resulting

in fire, explosion or risk ofinjury.

f ) Do not expose a battery pack or tool to

fire or excessive temperature. Exposure to

fire or temperature above 265 °F (130°C) may

causeexplosion.

g ) Follow all charging instructions and do not

charge the battery pack or tool outside the

temperature range specified in the instructions.

Charging improperly or at temperatures outside the

specified range may damage the battery and increase

the risk of fire.

6) Service

a ) Have your power tool serviced by a qualified

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool ismaintained.

b ) Never service damaged battery packs. Service

of battery packs should only be performed by the

manufacturer or authorized serviceproviders.

Safety Instructions for All Operations

a ) This power tool is intended to function as a

polisher. 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 ) Operations such as grinding, sanding, wire

brushing or cutting-off 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 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.

d ) 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.

e ) 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.

f ) 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.

g ) 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.

h ) 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.

ENGLISH

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.

Further Safety Instructions for All

Operations

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 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 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.

• These chargers are not intended for any uses other

than charging Mac Tools rechargeable batteries.

Any other uses may result in risk of fire, electric shock

orelectrocution.

• Do not expose the charger to rain orsnow.

• Pull by the plug rather than the cord when

disconnecting the charger. This will reduce the risk of

damage to the electric plug andcord.

• Make sure that the cord is located so that it will not

be stepped on, tripped over or otherwise subjected

to damage orstress.

• Do not use an extension cord unless it is absolutely

necessary. Use of improper extension cord could result in

risk of fire, electric shock orelectrocution.

• When operating a charger outdoors, always provide

a dry location and use an extension cord suitable

for outdoor use. Use of a cord suitable for outdoor use

reduces the risk of electricshock.

• An extension cord must have adequate wire size

(AWG or American Wire Gauge) for safety. The

smaller the gauge number of the wire, the greater the

capacity of the cable, that is, 16 gauge has more capacity

than 18gauge. An undersized cord will cause a drop in

line voltage resulting in loss of power and overheating.

When using more than one extension to make up the

total length, be sure each individual extension contains at

least the minimum wire size. The following table shows

the correct size to use depending on cord length and

nameplate ampere rating. If in doubt, use the next heavier

gauge. The lower the gauge number, the heavier thecord.

of use include but are not limited to: auto/marine/RV/

motorcycle detailing and finish correction, boat construction

and repair, and metal or concretefinishing.

DO NOT use under wet conditions or in presence of

flammable liquids orgases.

DO NOT let children come into contact with the tool.

Supervision is required when inexperienced operators use

thistool.

d. If charging problems persist, take the tool, battery

pack and charger to your local servicecenter.

4. The battery pack should be recharged when it fails to

produce sufficient power on jobs which were easily

done previously. DO NOT CONTINUE to use under these

conditions. Follow the charging procedure. You may

also charge a partially used pack whenever you desire

with no adverse effect on the batterypack.

5. Foreign materials of a conductive nature such as, but

not limited to, grinding dust, metal chips, steel wool,

aluminum foil, or any buildup of metallic particles

should be kept away from charger cavities. Always

unplug the charger from the power supply when there

is no battery pack in the cavity. Unplug the charger

before attempting toclean.

6. Do not freeze or immerse the charger in water or any

otherliquid.

Charger Cleaning Instructions



WARNING: Shock hazard. Disconnect the charger

from the AC outlet before cleaning. Dirt and grease

may be removed from the exterior of the charger using

a cloth or soft non-metallic brush. Do not use water or

any cleaningsolutions.

Wall Mounting

MCB112, MCB115, DCB107, DCB112, DCB113,

DCB115, DCB118, DCB132

These chargers are designed to be wall mountable or to

sit upright on a table or work surface. If wall mounting,

locate the charger within reach of an electrical outlet,

and away from a corner or other obstructions which may

impede air flow. Use the back of the charger as a template

for the location of the mounting screws on the wall. Mount

the charger securely using drywall screws (purchased

separately) at least 1” (25.4 mm) long, with a screw head

diameter of 0.28–0.35” (7–9mm), screwed into wood to an

optimal depth leaving approximately 7/32” (5.5 mm) of the

screw exposed. Align the slots on the back of the charger

with the exposed screws and fully engage them in theslots.

this operation. Once the battery pack has reached an

appropriate temperature, the yellow light will turn off and

the charger will resume the chargingprocedure.

A charger will not charge a faulty battery pack. The charger

refusing to light could indicate a problem with the charger

or a faulty batterypack..

NOTE: If the charger refuses to light, take the charger and

battery pack to be tested at an authorized servicecenter.

Leaving the Battery Pack In the Charger

The charger and battery pack can be left connected with

the charge indicator showing packcharged.

Hot/Cold Pack Delay

When the charger detects a battery pack that is too hot

or too cold, it automatically starts a Hot/Cold Pack Delay,

suspending charging until the battery pack has reached an

appropriate temperature. The charger then automatically

switches to the pack charging mode. This feature ensures

maximum battery packlife.

A cold battery pack may charge at a slower rate than a

warm batterypack.

The DCB118 charger is equipped with an internal fan

designed to cool the battery pack. The fan will turn on

automatically when the battery pack needs to becooled.

Never operate the charger if the fan does not operate

properly or if ventilation slots are blocked. Do not permit

foreign objects to enter the interior of thecharger.

Electronic Protection System

Li-Ion tools are designed with an Electronic Protection

System that will protect the battery pack against

overloading, overheating or deepdischarge.

The tool will automatically turn off if the Electronic

Protection System engages. If this occurs, place the lithium-

ion battery pack on the charger until it is fullycharged.

Important Charging Notes

1. Longest life and best performance can be obtained if

the battery pack is charged when the air temperature

is between 65°F – 75°F (18° C– 24°C). DO NOT charge

when the battery pack is below +40°F (+4.5°C), or

above +104°F (+40°C). This is important and will

prevent serious damage to the batterypack.

2. The charger and battery pack may become warm to the

touch while charging. This is a normal condition, and

does not indicate a problem. To facilitate the cooling of

the battery pack after use, avoid placing the charger or

battery pack in a warm environment such as in a metal

shed or an uninsulatedtrailer.

3. If the battery pack does not charge properly:

a. Check operation of receptacle by plugging in a lamp

or other appliance;

b. Check to see if receptacle is connected to a light

switch which turns power off when you turn out

the lights;

c. Move the charger and battery pack to a location

where the surrounding air temperature is

approximately 65°F – 75°F (18°C – 24°C);

WARNING: To reduce the risk of serious personal

injury, turn unit off and remove the battery pack

before making any adjustments or removing/

installing attachments or accessories. An

accidental start-up can causeinjury.

Polishing (Fig.F)

These instructions and suggestions are intended to

familiarize new operators in overall general operation of

power polishing. You will develop your own techniques

which will make the job easier and faster as you learn

powerpolishing.

• You should use utmost care when power polishing

around or over sharp objects and contours of the car

body. It is very important to use the correct pressure

while polishing various sections of an automobile body.

For example, light pressure should be applied when

polishing over sharp edges of body panels, or over

edges of the rain gutter along thetop.

• Since everyone does not use the same type of power

polish, we recommend you clean and polish a test

section on a flat area of the car first. From this test

section, you can judge the strength or cleaning action of

your powerpolish.

• Remember, all power polish is not the same. Different

brands will react differently on various painted surfaces.

Also, you are now using a rotary polisher with power

polish which is entirely different from any hand

application which you may have done before. Wash

the car before power polishing it. Washing will remove

loose dirt, scum, road salt, etc. which could act as an

abrasive and damage paint. Loose dirt, etc. will also

clog the polishing pad and you will have to clean it

moreoften.

• Without turning the tool on, grasp the handles of the

tool and pick it up (Fig.F). Keep the tool away from your

body and depress the trigger switch. Make sure you

have a firm grip on the handles and operate the tool

freely without forced effort or unnecessary pressure. The

side handle can be easily changed to either side of the

tool for left-handed or right-handedoperation.

NOTE: The high speed rubbing action of the polishing

bonnet upon the surface of an automobile can build a static

charge on the metal portions of this tool. This can result in a

sensation of a very short mild electric shock when the metal

area of the tool is touched, and will be more noticeable

on days when the humidity is low. This is a harmless

phenomenon but you are invited to bring the tool to a

MacTools service center where it can be checked to assure

that no electrical malfunction ispresent.

release the trigger switch. The tool will continue to run. To

turn the tool off from a locked-on position, squeeze and

release the trigger switchonce.

The variable speed trigger switch

5

has a no-volt release

function. In the event of a dead battery or other unexpected

shut down, the trigger switch needs to be cycled (depress

the trigger switch, release, then depress again) to restart

the tool.

Speed Control Wheel (Fig.A)

The maximum speed of your tool can be changed by

rotating the speed control wheel

3

to the desired setting.

The wheel incorporates detents to prevent inadvertent

wheel movement and to facilitate speed selection. For

added versatility, the trigger switch may be locked in its full

on position and tool speed changed by means of the speed

control wheel

3

alone.

The electronic speed control not only lets you select the

speed to suit the job, but also helps to maintain that speed

as you load the tool by pressing down. It’s this feature,

coupled with the variable speed trigger switch, that make

this tool such avalue.

The speed control wheel

3

can be set for any speed

between 800 and 2200 RPM and the variable speed switch

will then control tool speed from zero to the wheel setting.

For example: A control wheel setting of 2200 RPM will allow

the variable speed switch to operate the tool between zero

and 2200 RPM, depending on how far the trigger switch

is depressed. A wheel setting of 800 RPM would allow the

switch to operate the tool from zero to 800RPM.

The electronic speed control feature comes into play

whenever the trigger switch is fully depressed and the tool

is running at the selected speed determined by the setting

of the control wheel. As you load the tool by pushing it

down on the work surface, (with the trigger fully depressed)

the electronic circuit inside the tool will compensate

for the loading and maintain the selected speed. If the

speed selected by the control wheel is 2200 RPM, as in

the example above, the tool will maintain 2200 RPM, as it

isloaded.

It is important to remember two things about electronic

speed control:

1. The electronic speed control operates only when the

variable speed trigger switch

5

is fullydepressed.

2. The effect of electronic speed control is much easier to

observe at lower speed settings (1400 RPM and below),

than at high speeds. As the tool approaches 2000 RPM,

the effect is considerably lessdramatic.

Keep in mind that, with a conventional polisher running at

a typical no-load speed of 2200 RPM, the tool slows down

to about 2000 RPM under a polishing load. Your polisher

will continue to run at 2200 RPM (or any speed you select

with the control wheel) as a load is applied. Since it doesn’t

slow down, the speed may be greater than you’re used to,

so some extra caution should be observed until you get the

“feel” of your polisher. If you feel the speed is too great, you

can, of course, slow the speed down with either the trigger

switch or the controlwheel.

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

e ) Pour l’utilisation d’un outil électrique à

l’extérieur, se servir d’une rallonge convenant à

Polisseuse rotative à vitesse variable 180 mm (7 po) 20 V

MCM849

FRANÇAIS

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.

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) Utilisation et entretien du bloc-piles

a ) Ne recharger l’outil qu’au moyen du chargeur

précisé par le fabricant. L’utilisation d’un chargeur

qui convient à un type de bloc-piles risque de

provoquer un incendie s’il est utilisé avec un autre

type de b loc-piles.

b ) Utiliser les outils électriques uniquement avec

les blocs-piles conçus à cet effet. L’utilisation de

tout autre bloc-piles risque de causer des blessures ou

unincendie.

c ) Lorsque le bloc-piles n’est pas utilisé, le tenir

éloigné des objets métalliques, notamment

des trombones, de la monnaie, des clés, des

clous, des vis ou autres petits objets métalliques

qui peuvent établir une connexion entre les

deux bornes. Le court-circuit des bornes du bloc-piles

risque de provoquer des brûlures ou unincendie.

d ) En cas d’utilisation abusive, le liquide peut gicler

hors du bloc-piles; éviter tout contact avec ce

liquide. Si un contact accidentel se produit, laver

à grande eau. Si le liquide entre en contact avec

les yeux, obtenir également des soins médicaux.

Le liquide qui gicle hors du bloc-piles peut provoquer

des irritations ou desbrûlures.

e ) Ne pas utiliser de bloc-piles ou outil qui

a été endommagé ou modifié. Les unités

endommagées ou modifiées peuvent avoir une

réaction imprévisible résultant en un incendie,

une explosion ou un potentiel de blessure.

f ) Ne pas exposer de bloc-piles ou l’outil aux

flammes ou à des températures excessives.

L’exposition aux flammes ou à une température

au-dessus de 129°C (265°F) pourrait causer

uneexplosion.

g ) Suivre toutes les instructions de recharge et

ne rechargez pas le bloc-piles ou l’outil à des

températures hors de la plage de température

indiquée dans les instructions. Une recharge non

conforme ou à une température hors des limites

spécifiées peut endommager les piles et augmenter le

risque d’incendie.

6) 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.

b ) Ne jamais réparer des blocs-piles endommagés.

La réparation de blocs-piles doit seulement être

effectuée par le fabricant ou les fournisseurs de

serviceautorisé.

Consignes de sécurité propres à toute

utilisation

a ) Cet outil électrique a été conçu pour être utilisé

comme polisseuse. Lire toutes les consignes de

sécurité, les directives, les illustrations et les

caractéristiques techniques fournies avec cet

outil électrique. Tout manquement aux directives

suivantes pose des risques de chocs électriques,

d’incendie et/ou de blessuresgraves.

b ) Les opérations de ponçage, brossage métallique,

meulage ou découpe ne sont pas recommandées

avec cet outil électrique. Toute utilisation de cet

outil électrique dans un but autre que celui pour lequel

il a été conçu est dangereuse et pose des risques de

dommagescorporels.

c ) Ne pas utiliser des accessoires qui n’ont pas

été spécialement conçus pour cet outil ou

FRANÇAIS

recommandés par son fabricant. Le fait qu’un

accessoire peut être connecté à l’outil ne veut pas

automatiquement dire que son utilisation ne posera

aucunrisque.

d ) La vitesse nominale des accessoires utilisés

doit être équivalente ou supérieure à la vitesse

maximale apposée sur l’outil. Les accessoires

utilisés à une vitesse plus rapide que leur vitesse

nominale peuvent éclater ou se détacher de l’outil.

e ) Le diamètre externe et l’épaisseur de l’accessoire

utilisé doivent se conformer aux spécifications

de la plaque signalétique de l’outil électrique. Les

accessoires aux spécifications incorrectes ne peuvent

être ni maintenus ni contrôlés de façonadéquate.

f ) 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 seront

pas stables, vibreront de façon excessive et pourront

causer la perte de contrôle de l'outil.

g ) Ne pas utiliser d’accessoire endommagé.

Avant toute utilisation, vérifier que les

accessoires, comme les meules abrasives, ne

sont endommagés en aucune façon, que les

tampons de soutien ne sont pas fendus, qu’il

n’existe aucune fissure ou usure excessive, que

les fils des brosses métalliques ne sont ni lâches

ni endommagés. En cas de chute, vérifier que

l’outil électrique ou l’accessoire n’a pas été

endommagé, et remplacer toute pièce abîmée.

Après avoir inspecté et installé un accessoire, se

positionner, soi-même et tout individu présent,

hors du plan de rotation de l’accessoire et laisser

tourner l’outil une minute à sa vitesse à vide

maximale. En général, les accessoires endommagés

se brisent pendant le temps d’essai.

h ) Porter un équipement individuel de protection.

Selon l’application, utiliser une protection

faciale et des lunettes ou un masque de

protection. Si approprié, porter un masque

anti-poussières, une protection auditive, des

gants et un tablier d’atelier capables de vous

protéger contre toute projection abrasive ou tout

fragment. La protection oculaire doit pouvoir

arrêter toute projection de débris engendrés

par des opérations diverses. Le masque anti-

poussières, ou l’appareil de protection des voies

respiratoires, doit pouvoir filtrer les particules

engendrées par l’opération en cours. Toute

exposition prolongée à un haut niveau de décibels

peut occasionner une perte de l’acuitéauditive.

i ) Maintenir à distance toute personne étrangère

au travail en cours. Toute personne à l’intérieur

de l’aire de travail doit porter un équipement

individuel de protection. Des débris provenant de

la pièce à travailler ou d’un accessoire brisé pourraient

être éjectés et causer des dommages corporels au-delà

de l’aire de travailimmédiate.

j ) Positionner le cordon hors du chemin de

l’accessoire en rotation. En cas de perte de contrôle

de l’outil, le cordon pourrait être coupé ou arraché, et

les mains ou bras pourraient entrer en contact avec

l’accessoire enrotation.

k ) Attendre systématiquement l’arrêt complet de

l’accessoire avant de poser l’outil électrique.

L’accessoire en rotation pourrait s’accrocher à

une surface et vous faire perdre le contrôle de

l’outilélectrique.

l ) Ne pas laisser l’outil électrique tourner alors que

vous le transportez à votre côté. Tout contact

accidentel de l’accessoire en rotation pourrait faire

que ce dernier s’accroche aux vêtements et entre en

contact avec lecorps.

m ) Nettoyer régulièrement les orifices d’aération

de l’outil. Le ventilateur du moteur attirera de la

poussière à l’intérieur du boîtier et une accumulation

excessive de poussières métalliques pose des risques

d’électrocution.

n ) Ne pas utiliser cet outil électrique à proximité

de matériaux inflammables, car des étincelles

pourraient lesenflammer.

o ) Ne pas utiliser d’accessoires nécessitant

l’utilisation de réfrigérants fluides. L’utilisation

d’eau ou de réfrigérants fluides pose des risques

d’électrocution ou de chocsélectriques.

Consignes de sécurité additionnelles

propres à toute utilisation

Rebonds et avertissements afférents

Les rebonds sont la conséquence du grippage ou coinçage

d’une meule, d’un tampon de soutien, d’une brosse en rotation

ou de tout autre accessoire. Tout grippage ou coinçage

causera rapidement le blocage de l’accessoire en rotation, ce

qui projettera l’outil électrique non contrôlé dans la direction

opposée à l’accessoire en rotation au point dugrippage.

Par exemple, si une meule abrasive reste accrochée ou pincée

dans une pièce à travailler, le bord de la meule engagée au

point de grippage peut s’enfoncer dans la surface du matériau

et faire sauter ou rebondir la meule. La meule peut alors

rebondir en direction ou à l’opposé de l’utilisateur, selon le

sens du mouvement de la meule au point de grippage. Dans

ces conditions, il peut aussi arriver que les meules abrasives

sebrisent.

Les rebonds proviennent d’une utilisation inadéquate de

l’outil et/ou d’une procédure ou de conditions d’utilisation

incorrectes, et peuvent être évités en prenant les précautions

appropriées détaillées ci-après:

a ) Maintenir l’outil électrique fermement et

positionner les bras et le corps de façon à

pouvoir résister à toute force de rebonds. Utiliser

systématiquement la poignée auxiliaire, si

fournie, pour optimiser le contrôle de l’outil en

FRANÇAIS

Directives de sécurité spécifiques

supplémentaires pour les polisseuses

• Nettoyer l’outil régulièrement, particulièrement

après une utilisation intensive. La poussière et les

saletés contenant des particules métalliques s’accumulent

souvent sur les surfaces internes de l’outil et pourraient

créer un risque de chocélectrique.

• Ne pas faire fonctionner cet outil durant de longues

périodes. Les vibrations causées par le fonctionnement

de cet outil peuvent provoquer des blessures permanentes

aux doigts, aux mains et aux bras. Utiliser des gants

pour amortir davantage les vibrations, prendre

de fréquentes périodes de repos et limiter la durée

quotidienned’utilisation.

• L'interrupteur est en position verrouillée lorsqu'il

n'est pas utilisé et avant d'être branché à la source

d'alimentation ou à labatterie.

Consigne de sécurité supplémentaire



AVERTISSEMENT : ne jamais modifier l’outil

électrique ni aucun de ses composants, car il y a

risques de dommages corporels oumatériels.



AVERTISSEMENT: porter SYSTEMATIQUEMENT

des lunettes de protection. Les lunettes courantes NE

sont PAS des lunettes de protection. Utiliser aussi un

masque antipoussières si l'opération est poussiéreuse.

PORTER SYSTÉMATIQUEMENT UN ÉQUIPEMENT DE

SÉCURITÉ HOMOLOGUÉ:

• Protection oculaire ANSI Z87.1 (CAN/CSA Z94.3);

• Protection auditive ANSI S12.6 (S3.19);

• Protection des voies respiratoires

NIOSH/OSHA/MSHA.



AVERTISSEMENT: les scies, meules, ponceuses,

perceuses ou autres outils de construction peuvent

produire des poussières contenant des produits

chimiques reconnus par l’État californien pour causer

cancers, malformations congénitales ou être nocifs au

système reproducteur. Parmi ces produits chimiques,

on retrouve:

• Le plomb dans les peintures à base de plomb;

• La silice cristallisée dans les briques et le ciment,

ou autres produits de maçonnerie; et

• L’arsenic et le chrome dans le bois ayant subi un

traitementchimique.

Le risque associé à de telles expositions varie selon

la fréquence à laquelle on effectue ces travaux.

Pour réduire toute exposition à ces produits:

travailler dans un endroit bien aéré, en utilisant

du matériel de sécurité homologué, tel un masque

antipoussières spécialement conçu pour filtrer les

particulesmicroscopiques.

• Limiter toute exposition prolongée avec les

poussières provenant du ponçage, sciage, meulage,

perçage ou toute autre activité de construction.

Porter des vêtements de protection et nettoyer à

l’eau savonneuse les parties du corps exposées. Le

fait de laisser la poussière pénétrer dans la bouche, les

yeux ou la peau peut favoriser l’absorption de produits

chimiquesdangereux.



AVERTISSEMENT: cet outil peut produire et/

ou répandre de la poussière susceptible de causer

des dommages sérieux et permanents au système

respiratoire. Utiliser systématiquement un appareil

de protection des voies respiratoires homologué par

le NIOSH ou l’OSHA. Diriger les particules dans le sens

opposé au visage et aucorps.



AVERTISSEMENT: pendant l’utilisation, porter

systématiquement une protection auditive

individuelle adéquate homologuée ANSI S12.6

(S3.19). Sous certaines conditions et suivant la durée

d’utilisation, le bruit émanant de ce produit pourrait

contribuer à une perte de l’acuitéauditive.



ATTENTION : lorsque vous ne l’utilisez pas,

placez l’outil à l’envers à l’aide des porte-outils

sur une surface stable là où cela n’entraînera pas

un risque de trébuchement ou de chute. Certains

outils équipés d’un large bloc-piles peuvent tenir à la

verticale sur celui-ci, mais manquent alors destabilité.

• Prendre des précautions à proximité des évents,

car ils cachent des pièces mobiles. Vêtements amples,

bijoux ou cheveux longs risquent de rester coincés dans

ces piècesmobiles.

cas de rebonds ou de tout retour de couple au

démarrage. En prenant les précautions adéquates,

l’utilisateur pourra contrôler tout retour de couple ou

force derebond.

b ) Ne jamais approcher les mains de l’accessoire en

rotation. L’accessoire pourrait rebondir sur celles-ci.

c ) Ne pas positionner le corps dans l’espace que

pourrait occuper l’outil électrique en cas de

rebonds. Les rebonds projetteront l’outil dans la

direction opposée au mouvement de la meule au

point degrippage.

d ) Prendre des précautions supplémentaires pour

travailler des coins, des bords acérés, etc. Éviter

que l’accessoire rebondisse ou reste accroché.

Les coins, bords acérés ou les sursauts ont tendance

à retenir l’accessoire en rotation et causer la perte de

contrôle de l’outil, ou desrebonds.

e ) Ne pas rattacher une lame à chaîne coupante, à

sculpter ou une lame dentée. Ces lames posent des

risques de rebonds fréquents et de perte de contrôle

de l’outil.

Consignes de sécurité spécifiques propres

au polissage

a ) Ne laisser aucune portion lâche du bonnet de

polissage ou ses cordons de fixation tourner

librement. Dissimuler ou couper toute partie

excessive des cordons de fixation. Des cordons

lâches, en rotation libre, pourraient se prendre dans les

doigts ou s’accrocher à la pièce àtravailler.
