contact accidentally occurs, flush with water, ff liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) SERVICE

a) Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Specific Safety Rules

• Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "five" wire will

make exposed metal parts of the tool "live" and shock the operator.

• 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

• Wear safety goggles or other eye protection. Hammering and drilling operations cause chips to fly. Flying particles can cause permanent eye damage.

• Bits, sockets and tools get hot during operation. Wear gloves when touching them.

• 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: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY

EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI $12.6 ($3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

_ 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.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and

other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

General Safety Rules

_)_ WARNING! Read all instructions. Failure to follow all instructions listed below may

result in electric shock, fire and/or serious injury. The term "power tool" in all of the

warnings listed below refers to your mains-operated (corded) power tool or

battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) WORK AREA SAFETY

a) Keep work area clean and we# lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tooL Distractions can

cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock

b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the

power tooL Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. Replace or repair damaged cords. Make sure your extension cord is in good condition. Use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool's plug.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor

use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 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.

Recommended Minimum Wire Size for Extension Cords

Total Length of Cord 25 ft. 50 ft. 75 ft. 100 ft. 125 ft. 150 ft. 175 ft.

3) PERSONAL SAFETY

a) 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 influence of drugs, alcohol or medication. A moment of inattention while operating power tools may

result in serious personal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position before plugging

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

d) 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.

e) Do not overreach. Keep proper footing and balance at a# times. This enables better

control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and

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

g) ff devices are provided for the connection of dust extraction and collection

facilities, ensure these are connected and properly used. Use of these devices can reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a) 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.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool

that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack 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.

d) Store idle power tools out of the reach of children 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.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage

of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp

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

Charge Indicators

Some chargers are designed to detect certain problems that can arise with battery packs. Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack

into the charger. If the problem persists, try a different battery pack to determine ifthe charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned

to a service center or other collection site for recycling. If the new battery pack elicits the same trouble indication as the original, have the charger tested at an authorized service center.

HOT/COLD PACK DELAY Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is

hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has cooled. After the battery has cooled, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in the Hot

Pack Delay mode. PROBLEM POWER LINE

Some chargers have a Problem Power Line indicator.When the charger is used with some portable power sources such as generators or sources that convert DC to AC, the charger may

temporarily suspend operation, flashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits.

LEAVING THE BATTERY PACK INTHE CHARGER The charger and battery pack can be left connected with the red light glowing indefinitely. The

charger will keep the battery pack fresh and fully charged. NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack

has not been kept on maintenance charge, it may need to be recharged before use. A battery pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate

AC source. WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries are

still usable but should not be expected to perform as much work. The charger will indicate to replace battery pack.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack.

2. The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer.

3. If the battery pack does not charge properly: a. Check current at receptacle by plugging in a lamp or other appliance

b. Check to see if receptacle is connected to a light switch which turns power off when you

turn out the lights.

c. Move charger and battery pack to a location where the surrounding air temperature is

approximately 65°F - 75°F (18°- 24°C).

d. If charging problems persist, take the tool, battery pack and charger to your local service

center.

4. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure.You may also charge a partially used pack whenever you desire with no adverse affect on the battery pack.

5. Under certain conditions, with the charger plugged into the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean.

6. Do not freeze or immerse charger in water or any other liquid.

_ WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may

result. i_ CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of

the battery pack breaks or cracks, return to a service center for recycling.

Rdgles de sdcuritd - Gdndralitds

AVERTISSEMENT : Lire toutes ces directives. Tout manquement aux directives suivantes pose des risques de choc #lectrique, d'incendie et/ou de blessure

grave. Le terme , outil #lectrique _ dans tousles avertissements ci-apr#s se rapporte

votre outil #lectrique _ alimentation sur secteur (avec ill) ou par piles (sans ill).

CONSERVER CES DIRECTIVES

1) SI_CURITI_ - AIRE DE TRAVAIL

a) Maintenir I'aire de travail propre et bien eclairee. Les lleux encombres ou sombres

sont propices aux accidents.

b) Ne pas faire fonctionner un outil electrique clans une atmosphere explosive, en

presence par exemple de poussieres, gaz ou liquides inflammables. Les outils electriques peuvent engendrer des etincelles qui pourraient enflammer toute emanation ou poussiere ambiante.

c) Tenir les enfants, ou toute autre personne, eloignes pendant I'utilisation d'un outil

electrique. Toute distraction pourrait vous faire perdre la mMtrise de ce dernier.

2) SI_CURITI_ - I_LECTRICITI_

a) La fiche electrique de I'outil doit correspondre a la prise murale. Ne jamais

modifier la fiche en aucune fa_on. Ne jamais utiliser de fiche d'adaptation avec un outil electrique mis a la terre. L'utilisation de fiches d'origine et de prises appropriees

reduira les risques de choc electrique.

b) Eviter tout contact corporel avec des elements mis a la terre comme tuyaux,

radiateurs, cuisinieres ou refrigerateurs. Les risques de choc e/ectrique augmentent

Iorsque le corps est mis a la terre.

c) Ne pas exposer les outils electriques a la pluie ou a I'humidite. Toute penetration

d'un outil electrique par un liquide augmente les risques de choc electrique.

d) Ne pas utiliser le cordon de fa_on abusive. Ne jamais utiliser le cordon pour

transporter, tirer ou debrancher un outil electrique. Proteger le cordon de

la chaleur, de I'huile et de tout bord tranchant ou piece mobile. Les cordons endommages ou emmBles augmentent les risques de choc electrique.

e) Lors de I'utilisation d'un outil electrique a I'exterieur, n'utiliser que des railonges

con_ues pour I'exterieur. L'utilisation d'une rallonge congue pour I'exterieur redu# les risques de choc electrique. En cas d'utilisation d'une rallonge, s'assurer que les valeurs

nominales de la rallonge utilisee correspondent bien a celles de Ibutil alimente. L'usage d'une rallonge de calibre insuffisant causera une chute de tension entrMnant perte

de puissance et surchauffe. Le tableau ci-dessous illustre les calibres a utiliser selon la Iongueur de rallonge et I'intensite nominale indiquee sur la plaque signaletique. En cas de doutes, utiliser le calibre suivant. Plus le calibre est petit, plus la rallonge peut supporter de courant.

3) SI_CURITI_ PERSoNNELLE

a) Rester vigilant en tout temps et faire preuve de jugement pendant I'utilisation d'un

outil electrique. Ne pas utiliser d' outil electrique en cas de fatigue ou sous I'influence de drogues, d'alcool ou de medicaments. Tout moment d'inattention pendant

I'utilisation d'un outil electrique pose des risques de blessure grave.

b) Utiliser le materiel de securite approprie. Toujours porter des lunettes de protection.

Le fait de porter un masque anti-poussieres, des chaussures antiderapantes, un casque de securite ou des protecteurs auditifs Iorsque la situation le requiert reduira les risques

de blessure.

c) Eviter tout demarrage accidentel. S'assurer que I'interrupteur est en position

d'arrRt avant tout branchemenL Transporter un outi/ /e doigt sur /'interrupteur ou

brancher un outil electrique alors que I'interrupteur est en position de marche invite les accidents.

d) Retirer toute cle de reglage avant de demarrer I'outil. One cle laissee sur une piece

rotative d'un outil electrique pose des risques de blessure.

e) Ne pas effectuer de travaux hors de portee. Les pieds doivent rester bien ancres

au sol afin de maintenir son equilibre en tout temps. Cela permet de mieux maftriser I'outil electrique dans les situations imprevues.

f) Porter des vBtements appropries. Ne pas porter de vBtements amples ni de bijoux.

Maintenir cheveux, vBtements et gants eloignes des pieces mobiles. VBtements amples, bijoux ou cheveux longs risquent de rester coinces dans ces pieces mobiles.

Prendre des precautions autour des events car ils recouvrent des pieces mobiles.

g) Lorsque un dispositif de connexion a un systeme de depoussierage ou d' elimination

est fourni, s'assurer qu'il est connecte et utilise correctement. Eutilisation de ces dispositifs peut reduire les risques engendres par les poussieres.

4) UTILISATION ET ENTRETIEN DES OUTILS #LECTRIQUES

a) Ne pas forcer un outil electrique. Utiliser I'outil approprie au travail en cours. L'outil

approprie effectuera un meilleur travail, de faUGhplus s_re et a la vitesse pour laquelle il a ete con_u.

b) Ne pas utiliser un outil electrique dont I'interrupteur est defectueux. Tout appareil

dont I'interrupteur est defectueux est dangereux et doit 6tre repare.

c) Debrancher la fiche du secteur et/ou le bloc-piles de I'outil electrique avant de

faire tout reglage ou changement d'accessoire, ou avant de ranger ce dernier. Ces mesures preventives reduisent les risques de demarrage accidentel de I'appareil.

d) Apres usage, ranger les outils electriques hors de la portee des enfants, et ne

permettre a aucune personne n'etant pas familiere avec un outil electrique (ou son manuel d'instruction) d'utiliser ce dernier. Les outils peuvent 6tre dangereux entre

les mains des novices.

e) Entretenir les outils electriques. Wrifier les pieces mobiles pour s'assurer qu'eiles

sont bien alignees et tournent librement, qu'elles sont en bon etat et ne sont affectees d'aucune condition susceptible de nuire au bon fonctionnement de I'outil. En cas de dommage, faire reparer I'outil electrique avant toute nouvelle utilisation. Bien des accidents sont causes par des outils mal entretenus.

f) Maintenir tout outil de coupe bien aiguise et propre. Les outils de coupe bien

entretenus et aff_tes sont moins susceptibles de se coincer et sont plus faciles contrBler.

g) Utiliser un outil electrique, ses accessoires, meches, etc., conformement aux

presentes directives et suivant la maniere prevue pour ce type particulier d'outil electrique, en tenant compte des conditions de travail et du travail a effectuer. L'utilisation d'un outil electrique pour toute operation autre que celle pour laquelle il a ete congu est dangereuse.

5) UTILISATION ET ENTRETIEN DE L'OUTIL ALIMENT# PAR PILE

a) S'assurer que I'interrupteur se trouve a la position d'arrBt avant d'inserer le bloc-

piles. Inserer un bloc-piles dans un outil electrique dont I'interrupteur est a la position de marche risque de provoquer un accident.

b) Ne recharger I'outil qu'au moyen du chargeur precise par le fabricant. L'utilisation

d'un chargeur qui convient a un type de bloc-piles risque de provoquer un incendie s'il est utilise avec un autre type de bloc-piles.

c) Utiliser les outils electriques uniquement avec les blocs-piles con_us a cet effet.

L'utilisation de tout autre bloc-piles risque de causer des blessures ou un incendie.

d) Lorsque le bloc-piles n'est pas utilise, le tenir eloigne des objets metalliques,

notamment des trombones, de la monnaie, des cles, des clous, des vis, etc., qui

peuvent etablir une connexion entre les deux bornes. Mettre en court-circuit/es bornes du bloc-piles peut provoquer des brOlures ou un incendie.

e) En cas d'utilisation abusive, un liquide peut gicler hors du bloc-piles, eviter tout

contact. Si un contact accidentel se produit, laver a grande eau. Si le liquide entre en contact avec les yeux, obtenir des soins medicaux. Le liquide qui gicle hors du

bloc-piles peut provoquer des irritations ou des brDlures.

6) SERVICE

a) Faire entretenir les outils electriques par un reparateur qualifie en n'utilisant que

des pieces de rechange identiques. Cela permettra d'assurer I'integrite de I'outil

electrique et la securite de I'utilisateur.

R_gles de s_curit_ particuli_res

• Tenir I'outil par les surfaces de saisie isolees pour les travaux ob I'outil de coupe risque de toucher a des ills dissimules. Tout contact avec un fil "sous tension" provoquera

"l'electrisation" des parties metalliques exposees et I'electrocution de I'utilisateur.

• Utiliser des brides de fixation ou tout autre dispositif de fixation permettant de soute- nit et de retenir la piece sur une plate-forme stable. Tenir la piece avec la main ou contre son corps est instable et risque de provoquer une perte de maftrise de I'outiL

• Toujours porter des lunettes de protection ou toute autre protection oculaire. Lots du martelage ou du per_age, des debris sont rejetes dans I'air. Ces derniers peuvent causer des dommages oculaires permanent.

• Meches, douilles ou outils peuvent chauffer pendant leur utilisation. Toujours porter des gants avant de les manipuler.

• Ne pas utiliser cet outil pendant des periodes prolongees. Les vibrations causees par I'outil peuvent poser des risques pour les mains oules bras. Porter des gants pour amortir les

vibrations, et pour limiter les risques faire des pauses frequentes.

J_AVERTISSEMENT : TOUJOURS porter des lunettes de securite. Les lunettes de vue ne constituent PAS des lunettes de securite. Utiliser egalement un masque facial ou anti- poussiere si I'operation de decoupe genere de la poussiere. TOUJOURS UTILISER DE

L'EQUIPEMENT DE PROTECTION HOMOLOGUE :

• protection oculaire conforme a la norme ANSI Z87.1 (CAN/CSA Z94.3),

• protection auditive conforme a la norme ANSI $12.6 ($3.19) et

• protection des voies respiratoires conformes aux normes NIOSH/OSHA.

`&AVERTISSEMENT : Certaines poussieres creees par le pon_age, le sciage, le meulage et le forage mecaniques ainsi que d'autres activites de construction contiennent des produits

chimiques reconnus pour causer le cancer, des anomalies congenitales ou d'autres anomalies liees a la reproduction. Parmi ces produits chimiques, citons notamment :

• le plomb provenant des peintures au plomb ;

• la silice cristalline provenant des briques, du beton et d'autres materiaux de

ma_onnerie ;

• I'arsenic et le chrome provenant du bois traite (arseniate de cuivre et de chrome).

Le risque associe aces expositions varie selon la frequence de ces types de travaux. Pour reduire I'exposition aux produits chimiques : travailler dans un local bien ventile et utiliser du materiel de securite approuve, comme les masques antipoussieres specialement con_us pour filtrer les particules microscopiques.

• E:viter le contact prolonge avec la poussiere provenant du pon_age, du sciage, du meulage et du forage mecanique ainsi que d'autres activites de construction. Porter des vBtements de protection et laver les parties exposees au savon et a I'eau. La poussiere qui pourrait penetrer dans la bouche et les yeux ou se deposer sur la peau peut favoriser I'absorption de produits chimiques nocifs.

•&AVERTISSEMENT : Cet outil peut produire et repandre de la poussiere susceptible de

causer des dommages serieux et permanents au systeme respiratoire. Toujours utiliser un appareil respiratoire anti-poussieres approuve par le NIOSH ou I'OSHA. Diriger les particules dans le sens oppose du visage et du corps.

_AVERTISSEMENT :TOUJOURS porter une protection auditive appropriee conformement

la norme ANSI $12.6 ($3.19) Iors de I'utilisation du produit. Dans certaines conditions et

selon la duree d'utilisation, le bruit emis par ce produit peut contribuer a une perte auditive. _,MISE EN GARDE :Apres utilisation, ranger I'outil sur son cBte sur une surface stable

I_ ob il ne pourra faire ni trebucher ni tomber personne. Certains outils equipes d'un large bloc-pile peuvent tenir a la verticale sur ce dernier mais ils sont alors facilement destabilises.
