SAFETY WARNINGS

General power tool safety warnings

WARNING: Read all safety warnings, instructions, illustrations and speciications provided

with this power tool. Failure to follow all instructions listed below may result in electric shock, ire 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.

Cordless grinder safety warnings

Safety Warnings Common for Grinding, Sanding, Wire Brushing, or Abrasive Cutting-Off Operations:

1.This power tool is intended to function as a grinder, sander, wire brush or cut-off tool.

Read all safety warnings, instructions, illustrations and speciications provided with this

power tool. Failure to follow all instructions listed below may result in electric shock, ire and/or serious injury.

2.Operations such as polishing are not recommended to be performed with this power

tool. Operations for which the power tool was not designed may create a hazard and cause per - sonal injury.

3.Do not use accessories which are not specii-

cally designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

4.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 ly apart.

5.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.

6.Threaded mounting of accessories must

match the grinder spindle thread. For accessories mounted by langes, the arbour hole of the accessory must it the locating diameter of the lange. 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.

7.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 acces- sories will normally break apart during this test time.

8.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 stop-

ping small abrasive or workpiece fragments.

The eye protection must be capable of stopping lying debris generated by various operations. The dust mask or respirator must be capable of iltrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

9.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 ly away and cause injury beyond immediate area of operation.

10.Hold the power tool by insulated gripping surfaces only, when performing an operation

where the cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electric shock.

11.Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.

12.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.

13.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.

11 ENGLISH

14.Do not operate the power tool near lammable materials. Sparks could ignite these materials.

15.Do not use accessories that require liquid

coolants. Using water or other liquid coolants may result in electrocution or shock.

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.

1.Maintain a irm 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 reactions or kick- back forces, if proper precautions are taken.

2.Never place your hand near the rotating accessory. 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.

5.Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

Safety Warnings Speciic for Grinding and Abrasive

Cutting-Off Operations:

1.Use only wheel types that are recommended for your power tool and the speciic 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, accidental contact with wheel and sparks that could ignite clothing.

4.Wheels must be used only for recommended

applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are

intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.

5.Always use undamaged wheel langes that are

of correct size and shape for your selected wheel. Proper wheel langes support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel langes.

6.Do not use worn down wheels from larger power tools. Wheel intended for larger power tool

is not suitable for the higher speed of a smaller tool and may burst.

Additional Safety Warnings Speciic for Abrasive

Cutting-Off Operations:

1.Do not “jam“ the cut-off wheel or apply excessive pressure. Do not attempt to make an

excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the 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 wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise

kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.

4.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 kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.

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.

Safety Warnings Speciic for Sanding Operations:

1.Do not use excessively oversized sanding disc paper. Follow manufacturers recommen-

dations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

Safety Warnings Speciic 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.

12 ENGLISH

2.If the use of a guard is recommended for wire brushing, do not allow any interference of the

wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional Safety Warnings:

1.When using depressed centre grinding wheels, be sure to use only iberglass-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 lange (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 speciied surface of the wheel to perform 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.Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care.

10.Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels.

11.Use only langes speciied for this tool.

12.For tools intended to be itted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length.

13.Check that the workpiece is properly supported.

14.Pay attention that the wheel continues to rotate after the tool is switched off.

15.If working place is extremely hot and humid, or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure operator safety.

16.Do not use the tool on any materials containing asbestos.

17.When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation.

18.Cutting discs must not be subjected to any lateral pressure.

19.Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which causes tool breakage.

Metal particles created by such operation are so hot that they ignite dust and the ilter inside the vacuum

cleaner.

To avoid dusty environment caused by masonry cut- ting, use a dust collecting wheel guard and a vacuum cleaner.

Refer to the instruction manual attached to the dust collecting wheel guard for assembling and using it. ► Fig.17: 1. Dust collecting wheel guard 2. Hose of

the vacuum cleaner

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 bang or hit grinding disc or wheel onto work.

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 frequently kick and cause loss of control leading to 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 off the tool and wait until the wheel has come to a complete stop before putting the tool down.

CAUTION: ALWAYS hold the tool irmly with one hand on housing and the other on the side grip (handle).

Grinding and sanding operation

► Fig.18

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 off by use, the wheel may be worked in both

forward and backward direction.

Operation with abrasive cut-off / diamond wheel

Optional accessory

WARNING: When using an abrasive cut-off / diamond wheel, be sure to use only the special

wheel guard designed for use with cut-off wheels.

(In some European countries, when using a diamond wheel, the ordinary guard can be used. Follow the regulations in your country.)

WARNING: NEVER use cut-off wheel for side grinding.

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-off wheel (as in grinding) will cause

the wheel to crack and break, causing serious per- sonal injury.

WARNING: A diamond wheel shall be operated perpendicular to the material being cut.

Consignes de sécurité pour meuleuse sans il

Consignes de sécurité communes aux travaux de meulage, ponçage, brossage métallique ou tronçonnage abrasif :

1.Cet outil électrique est conçu pour être utilisé en tant que meuleuse, ponceuse, brosse métallique ou outil de tronçonnage. Veuillez lire les

consignes de sécurité, instructions, illustrations et spéciications qui accompagnent cet outil

électrique. Le non-respect de toutes les instructions indiquées ci-dessous peut entraîner une électrocution, un incendie et/ou de graves blessures.

2.Il est déconseillé d’effectuer des travaux de polissage avec cet outil électrique. Il y a risque de danger et de blessure si l’outil électrique est utilisé pour exécuter des travaux pour lesquels il n’a pas été conçu.

3.N’utilisez pas d’accessoires qui n’ont pas été conçus spéciiquement et recommandés par le fabricant de l’outil. Même si un accessoire peut être ixé sur l’outil électrique, cela ne garantit pas qu’il fonctionnera de manière sûre.

4.La vitesse nominale de l’accessoire doit être au moins égale à la vitesse maximum inscrite sur l’outil électrique. Les accessoires tournant plus vite que leur vitesse nominale peuvent se casser et voler en éclats.

5.Le diamètre extérieur et l’épaisseur de l’accessoire ne doivent pas dépasser la capacité

nominale de l’outil électrique. Les accessoires de taille incorrecte ne peuvent être protégés ou contrôlés adéquatement.

6.Le iletage des accessoires à monter doit correspondre à celui de l’axe de la meuleuse.

Pour les accessoires montés à l’aide de lasques, la taille de l’alésage de l’accessoire doit correspondre au diamètre du lasque.

Les accessoires qui ne sont pas bien adaptés à la taille de la pièce où ils sont montés sur l’outil

électrique se déséquilibreront, vibreront trop et pourront entraîner une perte de maîtrise de l’outil.

7.N’utilisez jamais un accessoire endommagé.

Avant chaque utilisation, assurez-vous que la meule abrasive est exempte de copeaux et is - sures, que la semelle n’est pas issurée, déchi -

rée ou trop usée, ou que la brosse métallique est exempte de ils métalliques lâches ou cassés. Si vous lâchez l’outil électrique ou un accessoire, assurez-vous qu’il n’est pas endommagé ou bien

remplacez l’accessoire endommagé. Après avoir vériié et posé un accessoire, assurez-vous que personne, y compris vous-même, ne se trouve dans la trajectoire de l’accessoire en rotation et faites tourner l’outil électrique à vitesse à vide maximale pendant une minute. Les accessoires endommagés se brisent généralement au cours de cette période d’essai.

8.Portez un équipement de protection individuelle. Suivant le type de travail à effectuer, utilisez

un écran facial, des lunettes à coques ou des lunettes de sécurité. Si nécessaire, portez un masque anti-poussière, des protège-tympans, des gants et un tablier de travail pouvant arrêter

les particules abrasives ou les fragments de pièce. La protection oculaire doit pouvoir arrêter les

débris volants produits par les diverses opérations.

Le masque anti-poussières ou le masque iltrant doit pouvoir iltrer les particules générées lors des tra - vaux. Une exposition prolongée à un bruit d’intensité élevée peut entraîner une perte auditive.

9.Assurez-vous que les passants demeurent à une distance sûre de la zone de travail. Toute personne pénétrant dans la zone de travail doit porter un équipement de protection indivi-

duelle. Des fragments de pièce ou un accessoire cassé peuvent être éjectés et blesser les per - sonnes au-delà de la zone immédiate de travail.

28 FRANÇAIS

10.Tenez l’outil électrique uniquement par ses surfaces de prise isolées, lors d’une opéra-

tion au cours de laquelle l’outil de coupe peut entrer en contact avec un il caché. Le contact avec un il « sous tension » mettra également « sous tension » les parties métalliques exposées

de l’outil électrique, pouvant ainsi causer un choc

électrique chez l’utilisateur.

11.Ne déposez jamais l’outil électrique avant que l’accessoire ne se soit parfaitement arrêté.

L’accessoire en rotation peut accrocher la surface et projeter l’outil électrique de telle sorte que vous en perdiez la maîtrise.

12.Ne transportez pas l’outil électrique tout en le laissant tourner. En cas de contact accidentel

avec l’accessoire en rotation, ce dernier risque d’accrocher vos vêtements et d’être entraîné vers votre corps.

13.Nettoyez régulièrement les oriices d’aération de l’outil électrique. Le ventilateur du moteur aspire la poussière à l’intérieur du carter, ce qui présente un danger électrique en cas d’accumulation excessive de poussières métalliques.

14.N’utilisez pas l’outil électrique près de matériaux inlammables. Les étincelles risqueraient d’enlammer ces matériaux.

15.N’utilisez pas d’accessoires nécessitant un liquide de refroidissement. L’utilisation d’eau ou d’un liquide de refroidissement comporte un risque d’électrocution ou de choc électrique.

Mises en garde concernant le choc en retour et autres dangers

Le choc en retour est une réaction soudaine qui survient lorsque la meule, la semelle, la brosse ou un autre accessoire en rotation se coince ou accroche. Lorsque

l’accessoire en rotation se coince ou accroche, il s’ar- rête soudainement et l’utilisateur perd alors la maîtrise de l’outil électrique projeté dans le sens contraire de sa rotation au point où il se coince dans la pièce.

Par exemple, si une meule abrasive accroche ou se

coince dans la pièce, son tranchant introduit au point de pincement risque d’y creuser la surface du matériau,

entraînant la sortie ou le déchaussement de la meule.

La meule peut alors dévier de sa trajectoire, vers l’uti - lisateur ou dans le sens opposé, selon la direction du mouvement de la meule au point de pincement. Dans ces conditions, la meule abrasive risque également de se briser.

Le choc en retour est le résultat d’une utilisation

incorrecte de l’outil électrique et/ou de l’inobservation des procédures ou conditions d’utilisation. Il peut être

évité en prenant les précautions adéquates indiquées ci-dessous.

1.Maintenez une poigne ferme sur l’outil électrique et placez corps et bras de façon à pouvoir résister à la force exercée par les chocs en retour. Utilisez toujours la poignée auxiliaire, s’il y en a une, pour avoir une maîtrise maximale de l’outil en cas de choc en retour ou de force de réaction exercée au moment du démarrage. L’utilisateur peut maîtriser les forces de réaction ou de choc en retour s’il prend les précautions adéquates.

2.Ne placez jamais la main près d’un accessoire en rotation. L’accessoire risquerait de passer sur votre main en cas de choc en retour.

3.Ne vous placez pas dans la zone vers laquelle

l’outil électrique se déplacera en cas de choc en retour. Le choc en retour projettera l’outil dans

le sens opposé au mouvement de la meule au point où elle accroche dans la pièce.

4.Soyez tout particulièrement prudent lorsque vous travaillez sur les coins, les arêtes vives, etc. Évitez de laisser l’accessoire sautiller ou

accrocher. L’accessoire en rotation a tendance

à accrocher dans les coins, sur les arêtes vives ou lorsqu’il sautille, ce qui comporte un risque de perte de maîtrise ou de choc en retour.

5.Ne ixez pas une chaîne de coupe, une lame à sculpter le bois ou une lame de scie dentée. De telles lames causent fréquemment des chocs en retour et des pertes de maîtrise.

Consignes de sécurité spéciiques aux opérations de meulage et de tronçonnage abrasif :

1.Utilisez exclusivement les types de meule recom-

mandés pour votre outil électrique, et le carter de protection conçu spéciiquement pour la meule

sélectionnée. Les meules pour lesquelles l’outil

électrique n’a pas été conçu ne pourront pas être pro - tégées correctement et se révèleront dangereuses.

2.La surface de meulage des meules à moyeu déporté doit être montée sous le plan de la lèvre du carter de protection. Si la meule n’est pas bien montée et dépasse le plan de la lèvre du carter de protection, celui-ci ne pourra pas assurer une protection adéquate.

3.Le carter de protection doit être solidement ixé

à l’outil électrique et placé de façon à assurer une sécurité maximale en ne laissant qu’une partie minimale de la meule exposée du côté de

l’utilisateur. Le carter de protection permet de protéger l’utilisateur des éclats de meule brisée, d’un

contact accidentel avec la meule et des étincelles qui pourraient enlammer ses vêtements.

4.Les meules ne doivent être utilisées que pour les applications recommandées. Par exemple : ne procédez pas au meulage avec le côté de la meule à tronçonner. Les meules à tronçonner abrasives étant conçues pour le meulage périphérique, elles risquent de voler en éclats si on leur applique une force latérale.

5.Utilisez toujours des lasques pour meule

en bon état, dont la taille et la forme correspondent à la meule sélectionnée. Des lasques pour meule adéquats soutiennent la meule et

réduisent ainsi les risques de rupture de la meule.

Les lasques pour meules à tronçonner peuvent être différents de ceux pour meules ordinaires.

6.N’utilisez pas de meules usées provenant d’outils électriques plus grands. Les meules conçues pour des outils électriques plus grands ne conviennent pas à la vitesse supérieure d’un outil plus petit et risquent d’éclater.

Consignes de sécurité supplémentaires spéciiques aux travaux de tronçonnage abrasif :

1.Évitez de « bloquer » la meule à tronçonner ou d’appliquer une pression excessive. N’essayez pas de couper trop profondément. Une meule trop sollicitée subira une surcharge et risquera de se tordre ou de se coincer dans la ligne de coupe, ce qui comporte un risque de choc en retour ou de bris de la meule.

29 FRANÇAIS

2.Ne vous placez pas directement derrière ou devant la meule en rotation. Lorsque la meule, en cours de fonctionnement, s’écarte de votre corps, le choc en retour potentiel risque de propulser la meule en rotation et l’outil électrique dans votre direction.

3.Lorsque la meule se coince ou lorsque vous interrompez la coupe pour une raison quelconque, mettez l’outil électrique hors tension et maintenez-le immobile jusqu’à ce que la meule cesse complètement de tourner. Ne tentez jamais de retirer la meule à tronçonner de la coupe pendant que la meule tourne,

sous peine de provoquer un choc en retour.

Identiiez la cause du grippage de la meule et prenez les mesures correctives pour y remédier.

4.Ne reprenez pas la coupe telle quelle dans la pièce. Attendez que la meule ait atteint sa pleine vitesse avant de la réintroduire soi-

gneusement dans la ligne de coupe. Si vous redémarrez l’outil électrique alors qu’il se trouve encore dans la pièce à travailler, la meule risquera de se coincer, de remonter hors de la ligne de coupe ou de provoquer un choc en retour.

5.Soutenez les panneaux ou les pièces de grande taille pour réduire les risques de coin-

cement de la meule et de choc en retour. Les pièces de grande taille ont tendance à ployer sous leur propre poids. Il est nécessaire de placer en dessous des cales à proximité de la ligne de coupe et près du rebord de la pièce de chaque côté de la meule.

6.Redoublez de précaution lorsque vous faites une « coupe en plongée » dans un mur ou toute autre surface pouvant cacher des struc-

tures. La meule, en dépassant derrière le mur ou la surface, peut couper des conduites de gaz ou d’eau, des ils électriques ou des objets pouvant causer un choc en retour.

Consignes de sécurité spéciiques aux travaux de ponçage :

1.N’utilisez pas de feuilles de papier abrasif trop grandes. Suivez les recommandations du fabricant pour choisir le papier abrasif. Une grande feuille de papier abrasif débordant du coussin de ponçage présente un risque de lacération et pourrait déchirer le disque, l’accrocher ou provoquer un choc en retour.

Consignes de sécurité spéciiques aux travaux de brossage métallique :

1.N’oubliez pas que des ils métalliques se

détachent de la brosse même lors de travaux ordinaires. Ne soumettez pas les ils métal -

liques à une surcharge en appliquant une pression excessive sur la brosse. Les ils métal- liques pénètrent facilement dans les vêtements légers et/ou dans la peau.

2.Si l’utilisation d’un carter de protection est recommandée pour le brossage métallique, assurez-vous que la meule ou brosse métallique ne gêne pas le carter de protection. Selon la charge de travail et l’intensité de la force centrifuge, le diamètre de la meule ou brosse métallique peut augmenter.

Consignes de sécurité supplémentaires :

1.Lors de l’utilisation des meules ordinaires à

moyeu déporté, assurez-vous d’utiliser exclusivement des meules renforcées de ibre de verre.

2.N’UTILISEZ JAMAIS une meule boisseau pour

pierre avec cette meuleuse. Cette meuleuse n’est pas conçue pour ces types de meule, et leur utilisation peut entraîner de graves blessures.

3.Prenez garde de ne pas endommager l’axe, le lasque (tout particulièrement la surface d’ins - tallation) ou le contre-écrou. La meule risque de casser si ces pièces sont endommagées.

4.Assurez-vous que la meule n’entre pas en contact avec la pièce avant de mettre l’outil sous tension.

5.Avant d’utiliser l’outil sur une pièce, faites-le tourner un instant à vide. Soyez attentif aux vibrations ou sautillements pouvant indiquer que la meule n’est pas bien posée ou qu’elle est mal équilibrée.

6.Utilisez la surface spéciiée de la meule pour meuler.

7.N’abandonnez pas l’outil alors qu’il tourne. Ne faites fonctionner l’outil qu’une fois que vous l’avez bien en main.

8.Ne touchez pas la pièce immédiatement après avoir terminé le travail ; elle peut être très chaude et vous brûler la peau.

9.Suivez les instructions du fabricant pour un montage adéquat et une utilisation appropriée des meules. Manipulez et rangez les meules soigneusement.

10.N’utilisez pas de bagues de réduction ou

d’adaptateurs vendus dans le commerce pour adapter des meules abrasives dont l’oriice central est grand.

11.N’utilisez que les lasques spéciiés pour cet outil.

12.Pour les outils destinés à être équipés d’une meule à oriice ileté, assurez-vous que le iletage dans la meule est sufisamment long pour accueillir la longueur de l’axe.

13.Assurez-vous que la pièce à travailler est correctement soutenue.

14.N’oubliez pas que la meule continue de tourner une fois l’outil éteint.

15.Si le lieu de travail est extrêmement chaud et humide, ou fortement pollué de poussières conductrices, utilisez un disjoncteur (30 mA) pour assurer la sécurité de l’utilisateur.

16.N’utilisez l’outil avec aucun matériau contenant de l’amiante.

17.Lorsque vous utilisez une meule à tronçonner, travaillez toujours avec le carter de meule de collecte de la poussière exigé par la réglementation locale.

18.Aucune pression latérale ne doit être exercée sur les disques de coupe.

19.N’utilisez pas de gants de travail en tissu pendant la tâche. Les ibres des gants en tissu peuvent pénétrer dans l’outil et le casser.

CONSERVEZ CES
