_ ARNING! Read and understand a# instructions. Failure to

follow all instructions listed below may result in electric shock,

fire and/or serious personal injury.

WORK AREA

* Keep your work area clean and well fit. 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 3plug 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

inju04 or death. To avoid these risks of inju04 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 if your 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 smafler 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 injuo4

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

clothing, and gloves away from moving parts. Loose clothing, jewel_ or long hair can be

caught in moving parts. Air vents often cover moving parts and shou 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 the job

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

* Do not use tool if switch does not turn it 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 forone 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 Instructions 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

injuo4 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 when=

ever you think the tool may have been dropped. Flaws may cause wheel breakage. 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 burns 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 aft times.

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

result.

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

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

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

construction activities contains chemicals known to cause cancer, birth defects or other

reproductive harm. Some examples of these chemicals are:

lead from lead-based paints,

crystalline silica from bricks and cement and other masonry products, and

arsenic and chromium from chemically-treated lumber (CCA).

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

reduce your exposure to these chemicals: work in a well ventilated area, and work with

approved safety equipment, such as those dust masks that are specially designed to filter out

microscopic particles.

_lectrique.

* Ne pas utiliser I'outil #lectrique clans des endroits mouill#s ni/'exposer _ la pluie;.l'in-

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

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

tenant par le cordon, ou utiliser ce dernier pour le d#brancher. On dolt tenir le cor-

don _ /'#cart des sources de chaleur, de Fhuile, 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 railonges

con_ues pour cet usage, comme ceiles de type W-A ou W, afin de r#duire les risques

de choc #lectrique. S'assurer que la rallonge est en mesure de porter le courant n#cessaire

I'outil. Une rallonge de calibre inferieur entrMnera 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 selon la Iongueur de la rallonge et I'intensite nominale indiquee sur la plaque

signal#tique. En cas de doute, utiliser le calibre suivant. Plus le calibre est petit, plus la ral-

Ionge peut porter de courant.

SI_CURIT¢ PERSONNELLE

* Rester vigilant en tout temps et faire preuve de jugement Iorsqu'on utilise un outil

#lectrique. Ne pas utiliser I'outil Iorsqu'on est fatigu# ou sous Finfluence de drogues,

d'alcool ou de m#dicaments, car un moment d'inattention pourrait entrMner des

blessures graves.

* Porter des v_tements appropri_s. Ne pas porter des v_tements amples ou des

bijoux. Couvrir ou attacher les cheveux longs. Garder les cheveux, les v#tements,

les bijoux et les gants #loign#s des pi#ces mobiles, car ceux-ci peuvent s'y co|ricer.

Se tenir #loigne des #vents puisque ces demiers pourraient camoufler des pibces mobiles.

* E:viter les d#marrages accidentels. S'assurer que I'interrupteur est en position d'ar-

r#t avant de brancher I'outil. Ne pas transporter I'outil en laissant le doigt sur I'interrup-

teur nile brancher Iorsque I'interrupteur est en position de marche, car cela pourrait causer

un accident.

* Retirer les cl#s de r#glage avant de d#marrer I'outil. Une cl# laissee sur une pibce rota-

tive pourrait entrafner des blessures.

* Ne pas trop #tendre les bras. Les pieds do|vent rester ancr#s fermement au sol afin

de maintenir son #quilibre en tout temps et de mieux mMtriser I'outil clans des situations

imprevues.

* Utiliser le materiel de s#curit# appropri#; toujours porter des lunettes de protection.

Porter un masque anti-poussibres, des chaussures antiderapantes, un casque de securite

ou des protecteurs auditifs Iorsque la situation le requiert.

UTIUSATION ET ENTRETIEN DE L'OUTIL

* Fixer et soutenir la piece sur une plate-forme stable au moyen d'une bride de serrage

ou de tout autre dispositif semblable. La pibce est instable Iorsqu'on la retient manuelle-

ment ou qu'on I'appuie contre le corps, ce qui pourrait faire perdre la mMtrise de I'outil.

* Ne pas forcer Foutil ni I'utiliser pour des travaux autres que ceux pour lesquels il a

#t# con_u. Pour obtenir de meilleurs resultats et prevenir les risques de blessure, laisser

I'outil couper a la vitesse pour laquelle fl aet# con_u.

* Ne pas utiliser I'outil Iorsque I'interrupteur marche-arr#t ne fonctionne pas. Tout outil

qui ne peut #tre command# au moyen de I'interrupteur est dangereux et dolt #tre repare.

* D#brancher I'outil de la source d'alimentation #lectrique avant d'effectuer un

r#glage, de changer un accessoire ou de ranger I'outil; ces mesures preventives

r#duisent les risques de d#marrage accidenteL

* Lorsqu'on n'utilise pas I'outil, le ranger hors de la port#e des enfants ou des personnes

non quafifiees. Les out|Is sont dangereux entre les mains de personnes inexperiment#es.

* Bien entretenir I'outil; s'assurer qu'il est toujours bien propre et aiguis#. Les out|Is

bien entretenus et dont les bords sont bien tranchants sont moins susceptibles de rester

coinc#s et sont plus faciles a ma_triser.

* V#rifier les pibces mobiles afin de s'assurer qu'eiles sont bien align#es et qu'eiles ne

restent pas co|riches. V#rifier egalement les pibces afin de s'assurer qu'il n'y a aucun

bris ni aucune autre condition susceptible de nuire au bon fonctionnement de Foutil.

Faire reparer Foutil si ce dernier est endommag# avant de s'en servir b nouveau, car

les accidents sont souvent causes par des out|Is mal entretenus.
