General Safety Rules

A ARNING! Read and understand all instructions. Failure to

WORK AREA

* Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or

fumes. Keep bystanders, children, and visitors away while operating a power tool Distractions

can cause you to lose control.

ELECTRICAL SAFETY , Grounded tools must be plugged into an outlet properly installed and grounded in

accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified

electrician if you are in doubt as to whether the outlet is properly grounded, ff the tools should electrically malfunction or break down, grounding provides a low resistance path to

carry electricity away from the user. This tool uses grounded construction (3 prong plug) to provide a means to transfer electrical energy safely away from the user in the event the tool electrically malfunctions, breaks down, or the tool case becomes five. Damage to, or loss of, one of the 3 plug blades; damage to the plug or cord, or failure to have the tool plugged into a

verified and continuously grounded electrical system, may result in electric shock, serious injury, or death. To avoid these risks of injury, the tool must, at all times, be maintained and in proper working order (cord, plug blades) and plugged into a continuously grounded electrical

system. (See also "Cleaning" in the Maintenance section.) Applicable only to Class I (grounded) tools.

* Double insulated tools are equipped with a polarized plug (one blade is wider than the

other.) This plug will fit in a polarized outlet only one way. ff the plug does not fit fully in the outlet, reverse the plug. ff it still does not fit, contact a qualified electrician to install

a polarized outlet. Do not change the plug in any way. Double insulation [] eliminates the need for the three wire grounded power cord and grounded power supply system. Applicable

only to Class II (double insulated) tools.

* Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock ffyour body is grounded.

* Don't expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

* Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an

outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

* When operating a power tool outside, use an outdoor extension cord marked "W-A" or

"W." These cords are rated for outdoor use and reduce the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and

nameplate ampere rating, ff in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

PERSONAL SAFETY

* Stay alert, watch what you are doing and use common sense when operating a power

tool Do not use tool while tired or under the influence of drugs, alcohol, or medication.

A moment of inattention while operating power tools may result in serious personal injury.

* Dress properly. Do not wear loose clothing orjewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be caught in moving parts. Air vents often cover moving parts and should also be avoided.

* Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with

your finger on the switch or plugging in tools that have the switch on invites accidents.

* Remove adjusting keys or wrenches before turning the tool on. A wrench or key that is

left attached to a rotating part of the tool may result in personal inju_

* Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,

hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

* Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead to loss of control

* Do not force tool Use the correct tool for your application. The correct tool will do thejob

better and safer at the rate for which it is designed.

* Do not use tool ff switch does not turn # on or off. Any tool that cannot be controlled with

the switch is dangerous and must be repaired.

* Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing the tool Such preventative safety measures reduce the risk of starting the tool accidentally.

* Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

* Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,

with sharp cutting edges are less likely to bind and are easier to control

* Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tools operation. If damaged, have the tool serviced before

using. Many accidents are caused by poorly maintained tools.

* Use only accessories that are recommended by the manufacturer for your model

Accessories that may be suitable for one tool may become hazardous when used on another

tool.

SERVICE

* Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

* When servicing a tool, use only identical replacement parts. Follow instructions in the

Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.

Additional Specific Safety Instructi_ns for Cut-Off

Machines

* Always use proper guard with grinding wheel. A guard protects operator from broken

wheel fragments and wheel contact.

* Accessories must be rated for at least the speed recommended on the tool warning

label Wheels and other accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be above tool speed as shown on tool nameplate.

* Hold tool by insulated gripping surfaces when performing an operation where the

cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.

, ALWAYS WEAR EYE PROTECTION WHEN USING THIS TOOL. * Use of accessories not specified in this manual is not recommended and may be

hazardous. Use of power boosters that would cause the tool to be driven at speeds greater

than its rated speed constitutes misuse.

* Do not use circular saw blades or any other toothed blades with this tool Serious

injury may result.

* Before using, inspect recommended accessory for cracks or flaws. If such a crack or

flaw is evident, discard the accessory. The accessory should also be inspected whenever you think the tool may have been dropped. Flaws may cause wheel break-

age. Do not set unit down on wheel

* When starting the tool with a new or replacement wheel installed, or if you are unsure

of the condition of the wheel, hold the tool in a well protected area and let it run for one minute, ff the wheel has an undetected crack or flaw, it should burst in less than one minute. Never start the tool with a person in line with the wheel This includes the operator.

* Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and

inspect the wheel for cracks or flaws.

* Direct sparks away from operator, bystanders or flammable materials. Sparks may be

produced while using a sander or grinder. Sparks may cause bums or start fires.

* Always use ball handle. Tighten the handle securely. The bail handle should always be

used to maintain control of the tool at all times.

* Never cut into area that may contain electrical wiring or piping. Serious injury may

result.

, Clean out your tool often, especially after heavy use. Dust and grit containing metal par-

ticles often accumulate on interior surfaces and could create an electric shock hazard.

* Do not operate this tool for long periods of time. Vibration caused by tool action may be

harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by

taking frequent rest periods.

,& WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-

struction activities contains chemicals known to cause cancer, birth defects or other reproduc- tive harm. Some examples of these chemicals are:

* lead from lead-based paints, * crystalline silica from bricks and cement and other masonry products, and * arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To

reduce your exposure to these chemicals: work in a weft ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out

microscopic particles.

CONSERVER CES DIRECTIVES

AIRE DE TRAVAIL

* L'aire de travail dolt #tre propre et bien #clair#e. Les 6tablis encombrGs et les endroits

sombres peuvent entraTner des accidents.

* Ne pas faire fonctionner des outils #lectriques clans des atmospheres explosives,

comme en presence de liquides, de gaz et de poussi_res inflammables. Les outils 61ectriques produisent des 6tincelles qui peuvent enflammer la poussibre ou les vapeurs.

* Tenir les enfants, les visiteurs ou toute autre personne _/'#cart Iorsqu'on utilise un

outil #lectrique; les distractions peuvent faire perdre la ma_trise de ce demier.

R#GLES DE SE_CURIT# RELATIVES A, L'#LECTRIClTI_

* Les outils mis _ la terre doivent #tre branch#s clans une prise correctement install#e

et mise _ la terre tel que I'indiquent les codes et r#g/ements en vigueur. Ne jamais retirer la broche de mise _ la terre ou modifier la prise en aucune fa_on. Ne pas utilis-

er de fiche d'adaptation. Consulter un #lectricien qualifi# s'il y a un doute en ce qui conceme la mise _ la terre de la prise. En cas de dGfaillance 61ectrique ou de bris de I'outil, la mise a la terre procure un chemin de faible resistance au courant afin de reduire

les risques de choc 61ectrique. Cet outil est muni d'un dispositif mis a la terre (fiche _ 3 broches) afin d'assurer la securit6 de I'utilisateur en d#rivant I'#nergie #lectrique loin de celui-ci en cas de defaillance #lectrique ou de panne de I'outil, ou encore, de mise sous

tension du boftier. Tout dommage ou perte de I'une des 3 lames, tout dommage subi par

la fiche oule cordon, oule branchement de I'outil clans un systbme non conforme non mis

la terre de fa_on continue, augmente les risques de choc #lectrique, de blessure grave

ou de mort. Afin d'#viter tout risque de blessure, I'outil dolt #tre entretenu en tout temps, maintenu en bon #tat de fonctionnement (cordon, lames des fiches) et branche a un sys-

teme conforme mis a la terre de fa_on continue. (Voir aussi la rubrique , Nettoyage _,clans

la section, Entretien _,.) Cette protection ne s'applique qu'aux outils de classe I (mis la terre).

* Les outils _ double isolation sont munis d'une fiche polaris#e (c'est-b=dire que I'une

des lames est plus large que /'autre), laque/le ne peut 6tre raccord#e qu'b une prise po/arisee et ce, clans un seul sens; on dolt I'inverser si on est incapable de/'enfon-

cer compl#tement. Si la fiche ne s'adapte toujours pas, on dolt faire appel _un #lec-

tricien qualifi# pour qu'il installe la prise appropri#e. On ne dolt jamais modifier la fiche. La double isolation #limine le besoin d'installer un cordon d'alimentation trifilaire et

un systbme d'alimentation #lectrique pourvus d'une mise a la terre; seuls les outils de

classe II (_ double isolation) sont munis d'une te/le protection.

* E:viter tout contact entre le corps et les #l#ments mis _ la terre, comme les tuyaux,

les radiateurs, les cuisini#res et les r#frig#rateurs, afin de r#duire les risques de choc _lectrique.

* Ne pas utiliser I'outil _lectrique dans des endroits mouill_s ni/'exposer b la p/uie;.l'in-

filtration d'eau a I'int#rieur de I'outil augmente les risques de choc #lectrique.

* Ne pas utiliser le cordon de mani#re abusive; on ne dolt pas transporter I'outil en le

tenant par le cordon, ou utiliser ce dernier pour le d#brancher. On dolt tenir le cor- don b I'ecart des sources de chaleur, de/'huile, des bords tranchants ou des pi#ces mobiles. Remplacer imm#diatement les cordons endommag_s, car ces demiers aug-

mentent les risques de choc #lectrique.

, Lorsqu'on utilise un outil #lectrique _/'ext#rieur, on ne dolt utiliser que des rallonges

con_ues pour cet usage, comme Relies de type W-A ou W, afin de r#duire les risques de choc #lectrique. S'assurer que la rallonge est en mesure de porter le courant necessaire

I'outil. Une rallonge de calibre inf#rieur entrafnera une chute de tension se traduisant par

une perte de puissance et une surchauffe. Le tableau ci-dessous illustre les calibres que I'on dolt utiliser scion la Iongueur de la rallonge et I'intensit# nominale indiquee sur la

Censignes de s_curit_ particuli_res relatives aux tron_onneuses

. Utiliser toujours le dispositif de protection qui convient _ la meule afin de prot_ger

I'operateur des fragments pouvant _tre projetes par une meule brisee ou d'emp_cher tout contact aver la meule.

. La vitesse des accessoires dolt correspondre b la vitesse minimale recommand_e

indiqu_e sur I'_tiquette d'avertissement de I'outil, car les meules et les accessoires qui sont regl_s a une vitesse trop _levee peuvent se briser et occasionner des blessures

Iorsque des fragments de metal sont projet_s.

. Tenir I'outil par les surfaces isolees pr_vues b cette fin Iorsqu'il risque d'entrer en

contact avec des ills caches ou son propre cordon, car de tels contacts peuvent met- tre les pibces metalliques de I'outil sous tension, engendrant des risques de choc _lec- trique.

. TOUJOURS PORTER DES LUNETTES DE PROTECTION LORSQU'ON UTILISE CET

OUTIL.

* L'utilisation d'accessoires non sp_cifi_s clans le present guide n'est pas recom-

mand#e et peut presenter un danger. L'utilisation d'un compresseur en vue de faire fonc- tionner I'outil a une vitesse superieure a la vitesse nominale recommandee constitue un emploi abusff de I'outil.

* Ne jamais utiliser de lames pour scie circulaire avec cet outil, ni de lames dentees, afin

d'#viter les risques de blessure grave.

, Avant d'utiliser un accessoire recommand#, le verifier afin de s'assurer qu'il n'y a

aucun bris ni fissure. Si on y trouve de tels d#fauts, mettre /'accessoire au rebut. /nspecter #galement /'accessoire chaque lois qu'il subit un choc, car un accessoire defectueux risque de briser la meule. Ne pas reposer I'outil sur la meule.

* Lorsqu'on d#marre I'outil (apr#s y avoir installe une meule neuve ou de rechange)

ou qu'on doute de son #tat de fonctionnement, se tenir clans un endroit bien prot#g# et le faire fonctionner pendant une minute, car si I'outil est fissure ou brise, il devrait

#clater en moins d'une minute. Ne jamais demarrer un outil Iorsque quelqu'un, y compris I'operateur, se tient directement devant luL

, E:viter de faire rebondir la meule durant son fonctionnement ou de/'utiliser sans

m#nagement. Si la meule subit de tels traitements, arr#ter I'outil et inspecter cette demibre.

* Orienter les #tincelles darts le sens oppos# de I'op#rateur ou de toute autre person-

ne se trouvant b proximitY, ainsi que des mat#riaux inflammables. Les meuleuses ou ponceuses peuvent produire des #tincelles susceptibles de causer des brOlures ou un

incendie.

* Toujours utiliser la poign#e de manoeuvre et la fixer solidement afin de ma_triser I'outil

en tout temps.

* Ne jamais couper clans une zone pouvant camoufler des tuyaux ou des ills #lec-

triques afin d'#viter les risques de blessure grave.

* Bien nettoyer I'outil p#riodiquement, surtout apr#s/'avoir utilis# Ionguement, car la

poussibre et les particules metalliques tendent a s'accumuler sur les surfaces internes et peuvent entrafner des risques de choc #lectrique.

* Ne pas utiliser I'outil pendant de Iongues p#riodes car les vibrations causees par ce

demier peuvent #tre endommageables aux mains et aux bras. Porter des Rants afin d'amortir les vibrations et restreindre I'exposition du corps aux vibrations en arr#tant fr#quemment.

AAVERTISSEMENT : Certains outils #lectriques, tels que les sableuses, les scies, les meules, les perceuses ou certains autres outils de construction, peuvent produire de la pous- siere contenant des produits chimiques susceptibles d'entrafner le cancer, des malformations congenitales ou pouvant #tre nocifs pour le systeme reproductif. Parmi ces produits chim-

iques, on retrouve :

* le plomb clans les peintures a base de plomb, * la silice cristalline clans les briques et le ciment et autres produits de ma_onnerie, * /'arsenic et le chrome clans le bois de sciage ayant subi un traitement chimique (comme

I'ars#niate de cuivre et de chrome).

Le risque associe a de telles expositions varie selon la fr#quence avec laquelle on effectue ces travaux. Pour reduire I'exposition _ de tels produits, il faut travailler clans un endroit bien a#r# et utiliser le materiel de securit# approprie, tel un masque anti-poussibres specialement

con_u pour flitter les particules microscopiques. * Eviter tout contact prolong# avec la poussi#re soulev#e par cet outil ou autres out-

ils #lectriques. Porter des v#tements de protection et nettoyer les parties expos#es du corps b /'eau savonneuse. S'assurer de bien se prot#ger afin d'#viter d'absorber par la bouche, les yeux ou la peau des produits chimiques nocifs.
