SAFETY WARNINGS

General power tool safety warnings

WARNING: Read all safety warnings, instruc-

tions, illustrations and specications provided

with this power tool. Failure to follow all instructions

listed below may result in electric shock, re and/or

serious injury.

Save all warnings and instruc-

tions for future reference.

The term "power tool" in the warnings refers to your

mains-operated (corded) power tool or BATTERY-

operated (cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

2. Do not operate power tools in explosive atmo-

spheres, such as in the presence of ammable

liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

Keep children and bystanders away while operating

a power tool. Distractions can cause you to lose control.

Electrical Safety

1. Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodied plugs and matching outlets will

reduce risk of electric shock.

2. Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and

refrigerators. There is an increased risk of elec-

tric shock if your body is earthed or grounded.

3. Do not expose power tools to rain or wet con-

ditions. Water entering a power tool will increase

the risk of electric shock.

4. 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.

3ENGLISH

5. 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.

6. If operating a power tool in a damp location is

unavoidable, use a Residual Current Device

(RCD) protected supply. Use of an RCD reduces

the risk of electric shock.

7. Power tools can produce electromagnetic

elds (EMF) that are not harmful to the user.

However, users of pacemakers and other similar

medical devices should contact the maker of their

device and/or doctor for advice before operating

this power tool.

8. Do not touch the power plug with wet hands.

9. If the cord is damaged, have it replaced by the

manufacturer or his agent in order to avoid a

safety hazard.

Personal Safety

1. Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use a power tool while you are tired or

under the inuence of drugs, alcohol or med-

ication. A moment of inattention while operating

power tools may result in serious personal injury.

2. Use personal protective equipment. Always

wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or

hearing protection used for appropriate conditions

will reduce personal injuries.

3. Prevent unintentional starting. Ensure the

switch is in the o-position before connecting

to power source and/or BATTERY pack, pick-

ing up or carrying the tool. Carrying power tools

with your nger on the switch or energising power

tools that have the switch on invites accidents.

4. 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.

5. Do not overreach. Keep proper footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves

away from moving parts. Loose clothes, jewel-

lery or long hair can be caught in moving parts.

7. If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

8. Do not let familiarity gained from frequent use

of tools allow you to become complacent and

ignore tool safety principles. A careless action

can cause severe injury within a fraction of a

second.

9. Always wear protective goggles to protect

your eyes from injury when using power tools.

The goggles must comply with ANSI Z87.1 in

the USA.

It is an employer's responsibility to enforce the

use of appropriate safety protective equipment

by the tool operators and by other persons in

the immediate working area.

Power tool use and care

1. Do not force the power tool. Use the correct

power tool for your application. The correct

power tool will do the job better and safer at the

rate for which it was designed.

Do not use the power tool if the switch does not turn

it on and o. Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

Disconnect the plug from the power source and/

or remove the BATTERY pack, if detachable, from

the power tool before making any adjustments,

changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of

starting the power tool accidentally.

4. Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with

the power tool or these instructions to operate

the power tool. Power tools are dangerous in the

hands of untrained users.

Maintain power tools and accessories. Check for

misalignment or binding of moving parts, break-

age of parts and any other condition that may

aect the power tool’s operation. If damaged, have

the power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

6. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

7. Use the power tool, accessories and tool bits

etc. in accordance with these instructions, tak-

ing into account the working conditions and

the work to be performed. Use of the power tool

for operations dierent from those intended could

result in a hazardous situation.

Keep handles and grasping surfaces dry, clean

and free from oil and grease. Slippery handles and

grasping surfaces do not allow for safe handling and

control of the tool in unexpected situations.

9. When using the tool, do not wear cloth work

gloves which may be entangled. The entangle-

ment of cloth work gloves in the moving parts may

result in personal injury.

Service

1. Have your power tool serviced by a qualied

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool is maintained.

2. Follow instruction for lubricating and chang-

ing accessories.

To reduce the risk of electric shock, this equipment has

a polarized plug (one blade is wider than the other).

This plug will t in a polarized outlet only one way. If the

plug does not t fully in the outlet, reverse the plug. If it

still does not t, contact a qualied electrician to install

the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Before connecting the tool to a

power source (receptacle, outlet, etc.) be sure the volt-

age supplied is the same as that specied on the name-

plate of the tool. A power source with voltage greater

than that specied for the tool can result in SERIOUS

INJURY to the user- as well as damage to the tool. If in

doubt, DO NOT PLUG IN THE TOOL. Using a power

source with voltage less than the nameplate rating is

harmful to the motor.

4ENGLISH

USE PROPER EXTENSION CORD. Make sure your exten-

sion cord is in good condition. 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 overheating. Table 1

shows the correct size to use depending on cord length and

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

gage. The smaller the gage number, the heavier the cord.

Grinder safety warnings

Safety warnings common for grinding, sanding,

wire brushing, or cutting-o operations:

This power tool is intended to function as a grinder,

sander, wire brush, hole cutter or cut-o tool. Read

all safety warnings, instructions, illustrations and

specications provided with this power tool. Failure

to follow all instructions listed below may result in

electric shock, re and/or serious injury.

Operations such as polishing are not to be performed with

this power tool. Operations for which the power tool was not

designed may create a hazard and cause personal injury.

Do not convert this power tool to operate in a way

which is not specically designed and specied by

the tool manufacturer. Such a conversion may result

in a loss of control and cause serious personal injury.

Do not use accessories which are not specically

designed and specied by the tool manufacturer.

Just because the accessory can be attached to your

power tool, it does not assure safe operation.

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 y apart.

6. 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.

The dimensions of the accessory mounting must

t the dimensions of the mounting hardware of the

power tool. Accessories that do not match the mount-

ing hardware of the power tool will run out of balance,

vibrate excessively and may cause loss of control.

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 maxi-

mum no-load speed for one minute. Damaged acces-

sories will normally break apart during this test time.

9. Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors,

gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments.

The eye protection must be capable of stopping

ying debris generated by various applications.

The dust mask or respirator must be capable

of ltrating particles generated by the particular

application. Prolonged exposure to high intensity

noise may cause hearing loss.

10.

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 y away and

cause injury beyond immediate area of operation.

11. Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting accessory may contact hid-

den 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.

12. Position the cord clear of the spinning acces-

sory. If you lose control, the cord may be cut or

snagged and your hand or arm may be pulled into

the spinning accessory.

13. Never lay the power tool down until the acces-

sory has come to a complete stop. The spinning

accessory may grab the surface and pull the

power tool out of your control.

14. 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.

15. 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.

16. Do not operate the power tool near ammable

materials. Sparks could ignite these materials.

17. Do not use accessories that require liquid

coolants. Using water or other liquid coolants

may result in electrocution or shock.

5ENGLISH

Kickback and related warnings:

Kickback is a sudden reaction to a pinched or snagged

rotating wheel, backing pad, brush or any other acces-

sory. Pinching or snagging causes rapid stalling of the

rotating accessory which in turn causes the uncon-

trolled 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 move-

ment 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.

Maintain a rm 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.

2. Never place your hand near the rotating acces-

sory. Accessory may kickback over your hand.

3. 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.

4. 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.

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 specic for grinding and cutting-o

operations:

1. Use only wheel types that are specied

for your power tool and the specic guard

designed for the selected wheel. Wheels for

which the power tool was not designed cannot be

adequately guarded and are unsafe.

2. The grinding surface of centre 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.

3. 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, acci-

dental contact with wheel and sparks that could

ignite clothing.

4. Wheels must be used only for specied appli-

cations. For example: do not grind with the

side of cut-o wheel. Abrasive cut-o wheels

are intended for peripheral grinding, side forces

applied to these wheels may cause them to

shatter.

5. Always use undamaged wheel anges that are

of correct size and shape for your selected

wheel. Proper wheel anges support the wheel

thus reducing the possibility of wheel breakage.

Flanges for cut-o wheels may be dierent from

grinding wheel anges.

6. 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.

7. 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.

Additional safety warnings specic for cutting-o operations:

1. Do not “jam” the cut-o wheel or apply exces-

sive 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 possibil-

ity of kickback or wheel breakage.

2. 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 spin-

ning wheel and the power tool directly at you.

3. When the wheel is binding or when interrupt-

ing a cut for any reason, switch o the power

tool and hold it motionless until the wheel

comes to a complete stop. Never attempt to

remove the cut-o 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.

Do not restart the cutting operation in the work-

piece. 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.

5. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-

back. 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.

6. Use extra caution when making a “pocket cut”

into existing walls or other blind areas. The

protruding wheel may cut gas or water pipes, elec-

trical wiring or objects that can cause kickback.

7. 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.

8. Before using a segmented diamond wheel,

make sure that the diamond wheel has the

peripheral gap between segments of 10 mm or

less, only with a negative rake angle.

Safety warnings specic for sanding operations:

1. Use proper sized sanding disc paper. Follow

manufacturers recommendations, when

selecting sanding paper. Larger sanding paper

extending too far beyond the sanding pad pres-

ents a laceration hazard and may cause snagging,

tearing of the disc or kickback.

6ENGLISH

Safety warnings specic for wire brushing

operations:

1. 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.

2. If the use of a guard is specied 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:

1. When using depressed centre grinding wheels,

be sure to use only berglass-reinforced

wheels.

2. NEVER USE Stone Cup type wheels with this

grinder. This grinder is not designed for these

types of wheels and the use of such a product

may result in serious personal injury.

3. Be careful not to damage the spindle, the

ange (especially the installing surface) or the

lock nut. Damage to these parts could result in

wheel breakage.

4. Make sure the wheel is not contacting the

workpiece before the switch is turned on.

5. Before using the tool on an actual workpiece,

let it run for a while. Watch for vibration or

wobbling that could indicate poor installation

or a poorly balanced wheel.

6. Use the specied surface of the wheel to per-

form the grinding.

7. Do not leave the tool running. Operate the tool

only when hand-held.

8. Do not touch the workpiece immediately after

operation; it may be extremely hot and could

burn your skin.

9. Do not touch accessories immediately after

operation; it may be extremely hot and could

burn your skin.

10. Observe the instructions of the manufacturer

for correct mounting and use of wheels.

Handle and store wheels with care.

11. Do not use separate reducing bushings or

adaptors to adapt large hole abrasive wheels.

12. Use only anges specied for this tool.

13. For tools intended to be tted with threaded

hole wheel, ensure that the thread in the wheel

is long enough to accept the spindle length.

14. Check that the workpiece is properly

supported.

15. Pay attention that the wheel continues to

rotate after the tool is switched o.

16. If working place is extremely hot and humid,

or badly polluted by conductive dust, use a

short-circuit breaker (30 mA) to assure opera-

tor safety.

17. Do not use the tool on any materials contain-

ing asbestos.

18. When use cut-o wheel, always work with

the dust collecting wheel guard if required by

domestic regulation.

19. Cutting discs must not be subjected to any

lateral pressure.

20. Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which

causes tool breakage.

21. Before operation, make sure that there is no

buried object such as electric pipe, water pipe

or gas pipe in the workpiece. Otherwise, it may

cause an electric shock, electrical leakage or gas

leak.

22. If a blotter is attached to the wheel, do not

remove it. The diameter of the blotter must be

larger than the lock nut, outer ange, and inner

ange.

23. Before installing a grinding wheel, always

check that the blotter part does not have any

abnormalities such as chips or cracks.

24. Tighten the lock nut properly. Overtightening

the wheel can cause breakage and insucient

tightening can cause uttering.

OPERATION

WARNING: It should never be necessary to

force the tool. The weight of the tool applies ade-

quate pressure. Forcing and excessive pressure

could cause dangerous wheel breakage.

WARNING: ALWAYS replace wheel if tool is

dropped while grinding.

WARNING:

NEVER hit the workpiece with the wheel.

WARNING:

Avoid bouncing and snagging the

wheel, especially when working corners, sharp

edges etc. This can cause loss of control and kickback.

WARNING:

NEVER use tool with wood cutting blades

and other saw blades. Such blades when used on a grinder fre-

quently kick and cause loss of control leading to personal injury.

WARNING:

Continued use of a worn-out wheel may

result in wheel explosion and serious personal injury.

CAUTION: Never switch on the tool when it

is in contact with the workpiece, it may cause an

injury to operator.

CAUTION: Always wear safety goggles or a

face shield during operation.

CAUTION: After operation, always switch o

the tool and wait until the wheel has come to a

complete stop before putting the tool down.

CAUTION: ALWAYS hold the tool rmly with

one hand on housing and the other on the side

grip (handle).

NOTE: A dual purpose wheel can be used for both

grinding and cutting-o operations.

Refer to the "Operation with wheel/disc" for grinding

operation, and refer to the "Operation with abrasive

cut-o / diamond wheel" for cutting-o operation.

Operation with wheel/disc

15°

Fig.24

Turn the tool on and then apply the wheel or disc to the workpiece.

In general, keep the edge of the wheel or disc at an

angle of about 15° to the workpiece surface.

During the break-in period with a new wheel, do not

work the grinder in forward direction or it may cut into

the workpiece. Once the edge of the wheel has been

rounded o by use, the wheel may be worked in both

forward and backward direction.

Operation with abrasive cut-o /

diamond wheel

Optional accessory

WARNING: Do not "jam" the 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, wheel breakage and overheating of the

motor may occur.

WARNING: Do not start the cutting operation

in the workpiece. Let the wheel reach full speed

and carefully enter into the cut moving the tool

forward over the workpiece surface. The wheel

may bind, walk up or kickback if the power tool is

started in the workpiece.

WARNING: During cutting operations, never

change the angle of the wheel. Placing side pres-

sure on the cut-o wheel (as in grinding) will cause

the wheel to crack and break, causing serious per-

sonal injury.

WARNING: A diamond wheel shall be oper-

ated perpendicular to the material being cut.

CONSIGNES DE

SÉCURITÉ

Consignes de sécurité générales

pour outils électriques

MISE EN GARDE : Veuillez lire toutes les

mises en garde, instructions, illustrations et

spécications qui accompagnent cet outil élec-

trique. Ne pas suivre toutes les instructions de la liste

ci-dessous peut entraîner une décharge électrique,

un incendie et/ou une grave blessure.

Conservez toutes les mises en

garde et instructions pour réfé-

rence future.

Le terme « outil électrique » qui gure dans les avertis-

sements fait référence à un outil électrique branché sur

une prise de courant (par un cordon d’alimentation) ou

alimenté par batterie (sans l).

Sécurité de la zone de travail

1. Maintenez la zone de travail propre et bien

éclairée. Les zones de travail encombrées

ou sombres ouvrent toute grande la porte aux

accidents.

2. N’utilisez pas les outils électriques dans les

atmosphères explosives, telles que celles où

sont présents des liquides, gaz ou poussières

inammables. Les outils électriques génèrent

des étincelles qui peuvent allumer les poussières

ou les vapeurs.

3. Gardez les enfants et personnes présentes

à l’écart pendant l’utilisation d’un outil élec-

trique. Toute distraction peut vous faire perdre la

maîtrise de l’outil.

19 FRANÇAIS

Sécurité en matière d’électricité

1. Les ches d’outil électrique doivent corres-

pondre à la prise de courant. Ne modiez

jamais la che, de quelque façon que ce soit.

N’utilisez aucune che d’adaptation avec les

outils électriques mis à la terre (à la masse).

Les ches non modiées et les prises de courant

correspondantes réduisent le risque de décharge

électrique.

2. Évitez tout contact avec les surfaces mises

à la terre ou à la masse, telles que celles des

tuyaux, radiateurs, cuisinières et réfrigéra-

teurs. Le risque de décharge électrique augmente

si votre corps est mis à la terre ou à la masse.

3. N’exposez pas les outils électriques à la pluie

ou à des surfaces mouillées. La pénétration

d’eau dans un outil électrique augmente le risque

de décharge électrique.

4. Ne maltraitez pas le cordon. N’utilisez jamais

le cordon pour transporter, tirer sur ou débran-

cher l’outil électrique. Gardez le cordon à

l’écart de la chaleur, de l’huile, des bords

tranchants ou des pièces en mouvement. Les

cordons endommagés ou enchevêtrés augmen-

tent le risque de décharge électrique.

5. Lorsque vous utilisez un outil électrique à l’ex-

térieur, faites-le avec un cordon prolongateur

conçu pour l’usage extérieur. Utiliser un cordon

conçu pour l’usage extérieur réduit le risque de

décharge électrique.

6. Si l’utilisation d’un outil électrique dans un

emplacement humide est inévitable, utilisez

une source d’alimentation protégée par un

disjoncteur diérentiel de fuite à la terre

(DDFT). Utiliser un DDFT réduit le risque de

décharge électrique.

7. Les outils électriques peuvent produire des

champs électromagnétiques (CEM) qui ne sont

pas préjudiciables à l’utilisateur. Les utilisa-

teurs de stimulateur cardiaque ou autres appareils

médicaux similaires doivent toutefois demander

conseil au fabricant et/ou à leur médecin avant

d’utiliser cet outil électrique.

8. Ne touchez pas la che d’alimentation avec les

mains mouillées.

9. Si le cordon est endommagé, faites-le rempla-

cer par le fabricant ou son représentant, pour

éviter les risques d’accident.

Sécurité personnelle

1. Restez vigilant, attentif à vos gestes et faites

preuve de bon sens pendant l’utilisation

d’un outil électrique. N’utilisez pas un outil

électrique lorsque vous êtes fatigué ou sous

l’inuence d’une drogue, de l’alcool ou d’un

médicament. Tout moment d’inattention pendant

l’utilisation des outils électriques peut entraîner

une grave blessure.

2. Utilisez l’équipement de protection individuel.

Portez toujours un protecteur pour la vue.

Utilisé dans les conditions adéquates, l’équi-

pement de protection - masque antipoussière,

chaussures de sécurité antidérapantes, casque de

protection ou protecteur auditif - réduit le risque de

blessures.

3. Évitez le démarrage accidentel. Assurez-vous

que l’interrupteur est sur la position d’arrêt

avant de connecter la source d’alimentation et/

ou la batterie, de saisir l’outil ou de le trans-

porter. Transporter les outils électriques avec le

doigt sur l’interrupteur, ou les connecter à une

source d’alimentation alors que l’interrupteur est

en position de marche ouvre toute grande la porte

aux accidents.

4. Retirez toute clé de serrage ou de réglage

avant de mettre l’outil électrique en marche.

Une clé laissée en place sur une pièce rotative de

l’outil électrique peut entraîner une blessure.

5. Ne vous étirez pas trop. Assurez-vous d’une

bonne prise au sol et d’une bonne position

d’équilibre en tout temps. Cela procure une

meilleur maîtrise de l’outil électrique dans les

situations imprévues.

Portez des vêtements adéquats. Ne portez ni

vêtements amples ni bijoux. Gardez vos cheveux,

vêtements et gants à l’écart des pièces en mouve-

ment. Les vêtements amples, bijoux ou cheveux longs

peuvent être happés par les pièces en mouvement.

7. Si des accessoires sont fournis pour raccor-

der un appareil d’aspiration et de collecte

des poussières, assurez-vous qu’ils sont

correctement raccordés et qu’ils sont utilisés

de manière adéquate. L’utilisation d’un appareil

de collecte des poussières permet de réduire les

risques liés à la présence de poussières dans l’air.

8. Ne vous laissez pas abuser, au point d’être sûr

de vous et d’ignorer les principes de sécurité,

par un sentiment de familiarité acquis par l’uti-

lisation fréquente des outils électriques. Un

geste irrééchi peut entraîner une grave blessure

en une fraction de seconde.

9. Portez toujours des lunettes à coques de pro-

tection pour protéger vos yeux contre les bles-

sures lors de l’utilisation d’outils électriques.

Les lunettes à coques doivent être conformes

à ANSI Z87.1 aux États-Unis.

L’employeur a la responsabilité d’imposer

l’utilisation d’équipements de protection de

sécurité adéquats aux utilisateurs des outils

électriques et à toute autre personne se trou-

vant dans la zone de travail immédiate.

Utilisation et entretien des outils électriques

1. Ne forcez pas l’outil électrique. Utilisez l’outil

électrique qui convient à votre application. Si

vous utilisez l’outil électrique adéquat et respectez

le régime pour lequel il a été conçu, il eectuera

un travail de meilleure qualité et plus sécuritaire.

2. N’utilisez pas l’outil électrique s’il n’est pas

possible de l’allumer et de l’éteindre avec son

interrupteur. Tout outil électrique dont l’interrup-

teur est défectueux représente un danger et doit

être réparé.

3. Débranchez la che de la source d’alimenta-

tion et/ou retirez la BATTERIE de l’outil élec-

trique, si elle est amovible, avant d’eectuer

tout réglage, de remplacer les accessoires

ou de ranger les outils électriques. De telles

mesures de sécurité préventives réduisent

le risque de démarrage accidentel de l’outil

électrique.

20 FRANÇAIS

4. Mettez les outils électriques sous tension

hors de la portée des enfants et ne laissez

aucune personne les utiliser si elle n’est pas

familiarisée avec l’outil électrique ou avec les

présentes instructions d’utilisation. Les outils

électriques représentent un danger entre les

mains de personnes qui n’en connaissent pas le

mode d’utilisation.

5. Veillez à l’entretien des outils électriques et

des accessoires. Assurez-vous que les pièces

mobiles ne sont pas désalignées ou coincées,

qu’aucune pièce n’est cassée et que l’outil

électrique n’a subi aucun dommage aectant

son bon fonctionnement. Si un outil électrique

est endommagé, faites-le réparer avant de

l’utiliser. De nombreux accidents sont causés par

des outils électriques mal entretenus.

6. Maintenez les outils tranchants bien aiguisés

et propres. Les outils tranchants dont l’entretien

est eectué correctement et dont les bords sont

bien aiguisés risquent moins de se coincer et sont

plus faciles à maîtriser.

Utilisez l’outil électrique, ses accessoires, ses

embouts, etc., en respectant les présentes ins-

tructions et en tenant compte des conditions de

travail et du type de travail à eectuer. L’utilisation

d’un outil électrique pour d’autres usages que ceux

prévus peut entraîner une situation dangereuse.

8. Gardez les poignées et surfaces de saisie

sèches, propres et exemptes d’huile et de

graisse. Les poignées et surfaces de saisie glis-

santes ne permettent pas la manipulation sécu-

ritaire et une bonne maîtrise de l’outil dans les

situations imprévues.

9. Lors de l’utilisation de l’outil, ne portez pas

de gants de travail en tissu qui risquent de

s’enchevêtrer dans l’outil. L’enchevêtrement de

gants de travail en tissu dans les pièces en mou-

vement peut entraîner une blessure.

Réparation

Faites réparer votre outil électrique par un répa-

rateur qualié qui utilise des pièces de rechange

identiques aux pièces d’origine. Le maintien de la

sûreté de l’outil électrique sera ainsi assuré.

2. Suivez les instructions de lubrication et de

remplacement des accessoires.

Pour réduire le risque de décharge électrique, cet équi-

pement est doté d’une che polarisée (une des lames

est plus large que l’autre). Cette che ne s’insère que

dans un seul sens dans une prise de courant polari-

sée. Si la che ne pénètre pas à fond dans la prise de

courant, insérez-la dans l’autre sens. Si elle ne s’insère

toujours pas à fond, contactez un électricien qualié

pour faire installer une prise de courant adéquate. Ne

modiez la che d’aucune façon.

MISE EN GARDE SUR LA TENSION : Avant de brancher l’ou-

til sur une source d’alimentation (prise murale, prise de cou-

rant, etc.), assurez-vous que la tension fournie est la même

que celle spéciée sur la plaque signalétique de l’outil. Une

source d’alimentation dont la tension est supérieure à celle

spéciée pour l’outil peut entraîner une GRAVE BLESSURE

pour l’utilisateur, ainsi qu’endommager l’outil. En cas de

doute, NE BRANCHEZ PAS L’OUTIL. L’utilisation d’une

source d’alimentation dont la tension est inférieure à celle

indiquée sur la plaque signalétique endommagera le moteur.

UTILISEZ UN CORDON PROLONGATEUR

APPROPRIÉ. Assurez-vous que votre cordon prolonga-

teur est en bonne condition. Lorsque vous utilisez un cor-

don prolongateur, assurez-vous qu’il est assez robuste

pour transporter le courant exigé par le produit. Un

cordon trop petit entraînera une baisse dans la tension

composée, ce qui causera une perte d’énergie et une

surchaue. Le tableau 1 indique la dimension de cordon
