General Power Tool Safety Warnings

_ ARNING! Read all safety warnings and all instructions. Failure to follow the warnings

and instructions may result in electric shock, fire and/or serious injury,

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well 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.

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. If operating a power tool in a damp location is unavoidable, use a ground fault circuit

interrupter (GFCI)protected supply, Use of a GFCI reduces the risk of electric shock.

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 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.

c) Prevent unintentional starting. Ensure the switch is in the off position before

connecting to power source and/or battery pack, picking up or carrying the tool Carrying power tools with your finger on the switch or energising 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 all times. This enables better

control of the power tool in unexpected situations.

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

and gloves away from moving parts. Loose clothes, jeweller}! or long hair can be caught in moving parts.

g) 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.

4) POWER TOOL USE AND CARE @ Do not force the power tool Use the correct power tool for your application. The

correct power too/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 ff on and off. Any power too/

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

c) Disconnect the plug from the power source andlor 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 too/

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 tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

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

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

g) Use the power tool, accessories and tool bits etc., in accordance with these

instructions taking into account the working conditions and the work to be

performed. Use of the power tool for operations different from those intended could result

in a hazardous situation.

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

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

Additional Safety Instructions for Rotary Hammers

• Wear ear protectors. Exposure to noise can cause hearing loss.

• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury,

• Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden 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.

• 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 operations cause chips to fly, Flying particles can cause permanent eye damage. Wear a dust mask or respirator for applications that generate dust. Ear protection may be required for most applications.

• Keep a firm grip on the tool at all times. Do not attempt to operate this tool without holding it with both hands. It is recommended that the side handle be used at all times. Operating this tool with one hand will result in loss of control Breaking through or encountering hard materials such as re-bar may be hazardous as well. Tighten the side handle securely before use.

• Do not operate this tool for long periods of time. Vibration caused by hammer action may be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by taking frequent rest periods.

• Do not recondition bits yourself. Chisel reconditioning should be done by an authorized specialist. Improperly reconditioned chisels could cause injury,

• Wear gloves when operating tool or changing bits. Accessible metal parts on the tool and bits may get extremely hot during operation. Small bits of broken material may damage bare

hands.

• Never lay the tool down until the bit has come to a complete stop. Moving bits could cause injury,

• Do not strike jammed bits with a hammer to dislodge them. Fragments of metal or material chips could dislodge and cause injury,

• Keep the power cord away from the rotating bit. Do not wrap the cord around any part of

your body, An electric cord wrapped around a spinning bit may cause personal injury and loss

of control.

• Air vents often cover moving parts and should be avoided. Loose clothes, jeweller}! or long hair can be caught in moving parts.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is

16gauge has more capacity than 18gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the

cord.

3. Ensure the bit is properly engaged. NOTE: The bit needs to move several centimeters in and out of the tool holder (M) when

properly engaged.

4. To remove the bit, pull back the locking sleeve and pull the bit out.

Two-Stage Clutch (Fig. 6)

NOTICE: Always turn the tool off before changing torque control settings or damage to tool may

result.

TWO-STAGE CLUTCH (D25762 ONLY)

Clutch Setting 1 (R)is designed for most hammerdrilling applications and is designed to easily clutch out when the drill bit encounters re-bar or other foreign substances.

Clutch Setting 2 (S) is designed for higher torque applications such as core-bits and deep hole hammerdrilling and is designed to clutch out at a higher torque threshold. Move the torque control lever (V)to setting 1 or 2 as needed for application.

NOTE: Allow the motor housing to rotate a little while changing torque. Each time the tool is plugged in, it will automatically default to clutch setting 1, the most

sensitive setting.

Electronic Speed and Impact Control (Fig. 6)

The electronic speed and impact control allows the use of smaller drill bits without the risk of bit breakage, hammerdrilling into light and brittle materials without shattering and optimal tool control for

precise chiseling. To set the control dial, turn the dial (G) to the desired level. The higher the number, the greater

the speed and impact energy. Dial settings make the tool extremely flexible and adaptable for many different applications. The required setting depends on the bit size and hardness of material

being drilled.

Mode Selector (Fig. 1)

CAUTION: Never change the mode while the unit is running.

A CAUTION: Do not change to hammerdrill mode with chisel bit in tool holder. Personal injury and damage to tool may result.

To select the required operating mode, rotate the mode selector (F) until the arrow points to the hammerdrilling or the chipping icon.

HAMMERDRILLING MODE (-T)

D25721, D25762

The tool simultaneously rotates and impacts the work. This mode is appropriate for all concrete and masonry operations.

CHIPPING MODE (T)

The spindle lock is engaged during chipping mode so the tool impacts the work without rotating. This mode is appropriate for light chipping, chiseling and demolition applications.

NOTE: In chipping mode, the hammerdrill can also be used as a lever to free a jammed drill bit. CHISEL BIT ADJUSTMENT (0)

Turn the mode selector to one of the chisel bit adjustment icons to adjust the chisel to the desired position. There are 24 possible positions to set the angle of the chisel. After finding the desired

position, slightly maneuver the chisel bit back and forth to ensure the chisel is properly engaged.

Indicator Lights (Fig. 6)

The yellow brush wear indicator LED (T) lights up when the carbon brushes are nearly worn out indicating that the tool needs servicing within the next 8 hours of use.

The red indicator LED (U) lights up if the lock-on slider (B) and/or electronic clutch is engaged in any mode except the chipping mode.

The red indicator LED (U)starts to flash if there is a fault with the tool or the brushes have completely worn out (refer to Repairs under Maintenance).

OPERATION

iL WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury,

•_ WARNING: Toreduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If hammerdril/ing thin material, use a wood "back-up" block to prevent damage

to the material _WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the

side handle properly installed and securely tightened. Failure to do so may result in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to

maximize control.

Proper Hand Position (Fig. 7)

WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as

shown in Figure 7. _ WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation

of a sudden reaction.

NOTE: Operating temperature of this tool is 19° to 104° F (-7 to +40 °C). Using the tool outside of this temperature range will decrease the life of the tool. Proper hand position requires one hand on the side handle (C), with the other hand on the main handle (D).

Trigger Switch (Fig. 1)

To turn the tool on, depress the trigger switch (A). To stop the tool, release the trigger switch. To lock the trigger switch on in the chipping mode only, push the lock-on slider (B) upwards while

depressing the trigger switch. To deactivate the lock-on slider, depress the trigger switch once then release. The lock-on slider may only be activated in chisel mode. The machine will stop running when

trying to engage the lock-on slider in drill mode. The motor will stop if the lock-on slider is activated when changing from chisel mode into drill mode.

SOFT START FEATURE

The soft start feature allows you to build up speed slowly, thus preventing the drill bit from walking off the intended hole position when starting. The soft start feature also reduces the immediate

torque reaction transmitted to the gearing and the operator if the hammer is started with the drill bit in an existing hole.

5. Assemble the centering bit and adapter shank into the core bit and insert into tool.

6. Mark the spot where the hole is to be drilled.

7. Place the centering bit on that mark and depress the trigger switch. NOTE: Some core drills require the removal of centering bit after about 1 cm of penetration. If

so, remove and continue hammerdrilling.

8. When hammerdrilling through a structure thicker than the depth of the core bit, break away

the round cylinder of concrete or core inside the bit at regular intervals. To avoid unwanted breaking away of concrete around the hole, first drill a hole the diameter of the centering bit completely through the structure. Then drill the cored hole halfway from each side of the

structure.

9. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and

before unplugging.

Chipping and Chiseling

1. Set the mode selector to chipping mode.

2. Set the impact control dial to desired setting (refer to Electronic Speed and Impact

Control).

NOTE: For SDS Max®models, only use SDS Max®insert tools.

4. Adjust the side handle (front or rear position).

5. Depress the trigger switch.

6. Apply only enough pressure to engage active vibration control (refer to Active Vibration

Control).

7. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and

before unplugging.

Hammerdrilling (Fig. 1)

_WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If hammerdrilling thin material, use a wood "back-up" block to prevent damage

to the material.

Set the mode selector (F)to hammerdrilling mode.

HAMMERDRILL OPERATION

1. When hammerdrilling, use just enough force on the hammer to keep it from bouncing excessively or "rising" off the bit. Too much force will cause slower hammerdrilling speeds and overheating.

2. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when hammerdrilling as this will cause clogging of the bit flutes and a slower hammerdrilling speed.

3. When hammerdrilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole.

4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of dust indicates the proper hammerdrilling rate.

MAINTENANCE

_ WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

Avertissements de sdcuritd gdndraux pour les outils

dlectriques

Le non-respect des avertissements et des directives pourrait se solder par un choc

_ AVERTISsEMENT ! Lire tousles avertissements de s_curit_ et toutes les directives.

dectrique, un incendie et/ou une blessure grave.

CONSERVER TOUS LES AVERTISsEMENTS ET TOUTES LES

DIRECTIVES POUR UN USAGE ULTERIEUR

Le terme _outil dectrique _, cite dans les avertissements se rapporte a votre outil electrique alimentation sur secteur (avec ill) ou par piles (sans ill).

1) SI_CURITI_ DU LIEU DE TRAVAIL

a) Tenir I'aire de travail propre et bien _clair_e. Les Iieux encombres ou sombres sont

propices aux accidents.

b) Ne pas faire fonctionner d'outils _lectriques clans un milieu d_flagrant, tel qu'en

presence de liquides, de gaz ou de poussi_res inflammables. Les outlls e/ectriques produisent des etincelles qui pourraient enflammer la poussiere ou les vapeurs.

c) Eloigner les enfants et les personnes a proximit_ pendant rutilisation d'un outil

_lectrique. Une distraction pourrait en faire perdre la ma_trisea I'utilisateur.

2) SI_CURITI_ EN MATIERE D'I_LECTRICITI_

a) Les fiches des outils _lectriques doivent correspondre a la prise. Ne jamais modifier

la fiche d'aucune faqon. Ne jamais utiliser de fiche d'adaptation avec un outil

_lectrique mis a la terre. Le risque de choc dectrique sera reduit par I'utilisation de fiches non modifiees correspondant a laprise.

b) Eviter tout contact physique avec des surfaces mises a la terre comme des tuyaux,

des radiateurs, des cuisini_res et des r_frig_rateurs. Le risque de choc dectrique est

plus deve si votre corps est mis a la terre.

c) Ne pas exposer les outils _lectriques a la pluie ou a I'humidit_. La penetration de I'eau

dans un outil dectrique augmente le risque de choc dectrique.

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

transporter, tirer ou d_brancher un outil _lectrique. Tenir le cordon _loign_ de la chaleur, de I'huile, des bords tranchants et des pi_ces mobiles. Les cordons

endommages ou enchev_tres augmentent les risques de choc dectrique.

e) Pour I'utilisation d'un outil _lectrique a I'ext_rieur, se servir d'une rallonge

convenant a cette application. L'uti/isation d'une rallonge conque pour/'exterieur reduira les risques de choc dectrique.

0 S'il est impossible d'_viter I'utilisation d'un outil _lectrique dans un endroit

humide, brancher I'outil clans une prise ou sur un circuit d'alimentation dot_s d'un disjoncteur de fuite a la terre (GFCI). L'utilisation de ce type de disjoncteur reduit les

risques de choc dectrique.

3) SI_CURITI_ PERSONNELLE

a) Etre vigilant, surveiller le travail effectu_ et faire preuve dejugement Iorsqu'un outil

_lectrique est utilis_. Ne pas utiliser d'outil _lectrique en cas de fatigue ou sous I'influence de drogues, d'alcool ou de m_dicaments. Un simple moment d'inattention

en utilisant un outil dectrique peut entra_nerdes blessures corporelles graves.

b) Utiliser des _quipements de protection individuelle. Toujours porter une protection

oculaire. L'utilisation d'equipements de protection comme un masque antipoussiere, des chaussures antiderapantes, un casque de securite ou des protecteurs auditifs Iorsque la situation le requiert reduira les risques de blessures corporelles.

c) Emp_cher les d_marrages intempestifs. S'assurer que I'interrupteur se trouve a la

position d'arr_t avant de relier I'outil a une source d'alimentation et/ou d'ins_rer un

bloc-piles, de ramasser ou de transporter I'outil. Transporter un outi/ e/ectrique a/ors que le doigt repose sur I'interrupteur ou brancher un outil dectrique dont I'interrupteur est la position de marche risque de provoquer un accident.

d) Retirer toute cl_ de r_glage ou cl_ avant de d_marrer I'outil. Une cle ou une cle de

reglage attachee a une pattie pivotante de I'outil dectrique peut provoquer des blessures corporelles.

e) Ne pas trop tendre les bras. Conserver son _quilibre en tout temps. Cela permet de

mieux ma_triser I'outil dectrique dans les situations imprevues.

0 S'habiller de mani_re appropri_e. Ne pas porter de v_tements amples ni de bijoux.

Garder les cheveux, les v_tements et les gants a I'_cart des pi_ces mobiles. Les v_tements amples, les bijoux ou les cheveux longs risquent de rester coinces dans les pieces

mobiles.

g) Sides composants sent fournis pour le raccordement de dispositifs de d_poussi_rage

et de ramassage, s'assurer que ceux-ci sont bien raccord_s et utilis_s. L'utilisation

d'un dispositif de depoussierage peut reduire les dangers engendres par les poussieres.

4} UTILISATION ET ENTRETIEN D'UN OUTIL #LECTRIQUE

a) Ne pas forcer un outil _lectrique. Utiliser I'outil _lectrique appropri_ a I'application.

L'outil dectrique approprie effectuera un meilleur travail, de faqon plus sore eta la vitesse

pour laquelle il a ete conqu.

b) Ne pas utiliser un outil _lectrique dont I'interrupteur est d_fectueux. Tout outil

dectrique dont /'interrupteur est defectueux est dangereux et doit _tre repare.

c) D_brancher la fiche de la source d'alimentation et/ou du bloc-piles de I'outil

_lectrique avant de faire tout r_glage ou changement d'accessoire ou avant de ranger I'outil. Ces mesures preventives reduisent les risques de demarrage accidentel de

I'outil dectrique.

d) Ranger les outils _lectriques hers de la pottle des enfants et ne permettre

aucune personne n'_tant pas famili_re avec un outil _lectrique ou son mode d'emploi d'utiliser cet outil. Les outlls dectriques deviennent dangereux entre/es mains d'utilisateurs inexperimentes.

e) Entretien des outils _lectriques. V_rifier si les pi_ces mobiles sent mal align_es ou

coinc_es, si des pi_ces sent bris_es ou pr_sentent toute autre condition susceptible de nuire au ben fonctionnement de I'outil _lectrique. En cas de dommage, faire r_parer I'outil _lectrique avant toute nouvelle utilisation. Beaucoup d'accidents sont causes par des outils dectriques mal entretenus.

0 S'assurer que les outils de coupe sent aiguis_s et propres. Les outlls de coupe bien

entretenus et affOtes sont moins susceptibles de se coincer et sont plus faciles a ma_triser.

g) Utiliser I'outil _lectrique, les accessoires, les forets, etc. conform_ment aux

pr_sentes directives en tenant compte des conditions de travail et du travail

effectuer. L'utilisation d'un outil dectrique pour toute operation autre que celle pour laquelle IIa ete conqu est dangereuse.

5) RI_PARATION

a) Faire r_parer I'outil _lectrique par un r_parateur professionnel en n'utilisant que

des pi_ces de rechange identiques. Celapermettra de maintenir une utilisation securitaire

de I'outil dectrique.

Consignes de s_curit_ additionnelles propres aux marteaux

rotatifs

• Porter un dispositif de protection auditif. Le bruit en resultant pourrait occasionner une perte de I'acuite auditive.

• Utiliser la/les poign_e(s) auxiliaire(s) si fournie(s) avec I'outil. Une perte de contr61e de

I'outil pourrait occasionner des dommages corporels.

• Tenir I'outil _lectrique par les surfaces isol_es pr_vues a cet effet pendant toute

utilisation ob I'organe de coupe pourrait entrer en contact avec des ills _lectriques caches ou son propre cordon. Tout contact de I'organe de coupe avec un fil sous tension

mettra les parties metalliques exposees de I'outil dectrique sous tension et dectrocutera I'utilisateur.

• Utiliser des serre-joints, ou tout autre moyen, pour fixer et immobiliser le mat_riau sur

une surface stable. Tenir lapiece a la main ou contre son corps offre une stabi/ite insuffisante

qui pourrait vous en faire perdre le contr61e.

• Porter des lunettes de protection ou toute autre protection oculaire. Le martelage

pourrait faire voltiger des eclats. Ces particules volantes pourraient occasionner des dommages

oculaires permanents. Porter un masque anti-poussieres ou un appareil de protection des voles respiratoires pour toute application productrice de poussieres. Une protection auditive peut

s'averer necessaire pour la plupart des applications.

• Maintenir syst_matiquement I'outil fermement. Ne pas tenter d'utiliser cet outil

sans le maintenir a deux mains./I est recommande d'utiliser systematiquement la poignee

laterale. Le fait d'utlliser cet outil a une main pourra vous en faire perdre le contr61e. Traverser ou rencontrer des materiaux durs comme les armatures peut aussi s'averer dangereux. Resserrer

soigneusement la poignee laterale avant toute utilisation.

• Ne pas utiliser cet outil pendant des p_riodes de temps prolong_es. Les vibrations

causees par la percussion peuvent poser des risques pour les mains ou les bras. Porter des

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

• Ne pas remettre b neuf les forets soi-m_me. La remise a neuf de tout burin dolt _tre

effectuee par un specialiste agree. Tout burin remis a neuf incorrectement pose des risques de

dommages corporels.

• Porter des gants Iors de I'utilisation de I'outil ou le changement de m_che. Les parties

metalliques accessibles de I'outil et des meches/forets pourraient s'averer brOlantes lots de I'utilisation. De petits debris de materiau pourraient aussi blesser les mains nues.

• Attendre syst_matiquement I'arr_t complet de la m_che/foret avant de d_poser I'outil

o_Jque ce soit. Des forets/meches en rotation posent des risques de dommages corporels.

• Ne pas donner des coups de marteau sur des forets/m_ches coinc_s pour les d_loger.

Des fragments de metal ou de materiau pourraient _tre ejectes et causer des dommages corporels.

• Maintenir le cordon d'alimentation a I'_cart d'une m_che en rotation. Ne pas enrouler

le cordon autour d'une partie quelconque de votre corps. Un cordon electr/que enroule

autour d'une meche en rotation pose des risques de dommages corporels et de perdre le contr61e de I'outll.

• Prendre des precautions a proximit_ des _vents, car ils cachent des pi_ces mobiles.

V_tements amples, bijoux ou cheveux longs risquent de rester coinces dans ces pieces mobiles.

• Pour la s_curit_ de I'utilisateur, utiliser une rallonge de calibre ad_quat (AWG, American Wire Gauge [calibrage am_ricain normalis_ des ills _lectriques]). Plus le

calibre est petit, et plus sa capacite est grande. Un calibre 16, par exemple, a une capacite superieure a un calibre 18. L'usage d'une rallonge de calibre insuffisant causera une chute de

tension qui entra_neraperte de puissance et surchauffe. Si plus d'une rallonge est utilisee pour obtenir une certaine Iongueur, s'assurer que chaque rallonge presente au moins le calibre de

fil minimum. Le tableau ci-dessous illustre les calibres a utlliser selon la Iongueur de rallonge et I'intensite nominale indiquee sur la plaque signaletique. En cas de doute, utiliser le calibre

suivant. Plus le calibre est petit, plus la rallonge peut supporter de courant.

_,AVERTISsEMENT : porter SYSTEMATIQuEMENT des lunettes de protection. Les lunettes

courantes NE sont PAS des lunettes de protection. Utlliser aussi un masque antipoussieres si la decoupe dolt en produire beaucoup. PORTER SYSTEMATIQuEMENT UN EQUIPEMENT DE

SECURITE HOMOLOGUE :

• Protection oculaire ANSI Z87.1 (CAN/CSA Z94.3) ;

• Protection auditive ANSI S 12.6 ($3.19) ;

• Protection des voles respiratoires NIOSH/OSHA/MSHA.

J_AVERTISsEMENT : les scies, meules, ponceuses, perceuses ou autres outlls de construction

peuvent produire des poussieres contenant des produits chimiques reconnus par I'Etat califomien pour causer cancers, malformations congenitales ou _tre nocifs au systeme reproducteur. Parmi

ces produits chimiques, on retrouve :

• Le plomb dans les peintures a base de plomb ;

• La silice cristallisee dans les briques et le ciment, ou autres produits de maqonnerie ; et

• L'arsenic et le chrome dans le bois ayant subi un traitement chimique.

Le risque associe a de telles expositions varie selon la frequence a laquelle on effectue ces travaux. Pour reduire toute exposition aces produits : travailler dans un endroit bien aere, en utllisant du
