General Power Tool Safety Warnings

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

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

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

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.

f) 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.

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.

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

a) The Do not force the power tool. Use the correct power tool for your application.

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 tool’s 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.

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

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 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, jewellery 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

16 gauge has more capacity than 18 gauge. 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.

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 S12.6 (S3.19) 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 the State of California 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.

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.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and

permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection

appropriate for the dust exposure. Direct particles away from face and body.

WARNING: Always wear proper personal hearing protection that conforms to ANSI

S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product

may contribute to hearing loss.

Side Handle (Fig. 2–4)

D25721, D25762

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.

The side handle clamps to the front barrel (collar) and may be rotated 360° to permit right- or left-

hand use. For operating convenience, the side handle can be installed in front or rear positions.

TO MOUNT IN FRONT POSITION (FIG. 2)

1. Unscrew the side handle (C) and and clamp wheel (H). Remove the side handle clamp (J) which

will allow disassembly of the remaining parts.

2. Snap the steel ring (K) over the collar (L) behind the tool holder (M). Squeeze both ends of the

steel ring together. Mount the bushing (N) and insert the pin (O).

3. Slide the side handle clamp (J) onto the bushing (N) while keeping the pin (O) centered. Lightly

screw the clamp wheel (H) onto the busing (N)—do not tighten.

4. Screw the side handle (C) into the clamp wheel (H) and tighten.

5. Rotate the side handle mounting assembly to the desired position. For hammerdrilling

horizontally with a heavy drill bit, place the side handle assembly at an angle of approximately

20° to the tool for optimum control.

6. Lock the side handle mounting assembly in place by securely tightening the clamp wheel (H)

so that the assembly will not rotate.

TO MOUNT IN REAR POSITION (FIG. 3)

1. Unscrew the side handle (C) and remove it from the side handle mounting assembly. Leave the

side handle mounting assembly in the front position.

2. Securely screw the side handle directly into one of the rear side handle positions (I) on either

side of the tool.

1. Unscrew the side handle knob (Q).

2. Slide the side handle assembly over the tool holder (M) and onto the collar (L) in the mounting

area (W). The correct position of the side handle is between head and middle of the tube.

3. Adjust the side handle (C) to the desired angle.

4. Slide and rotate the side handle to the desired position.

5. Lock the side handle in place by securely tightening the knob (Q) so that the side handle

assembly will not rotate.

SHOCKS Active Vibration Control® System (Fig. 1)

For best vibration control, hold the tool with one hand on the main handle (D) and the other hand

on the side handle (C). Apply just enough pressure so the hammer is approximately mid-stroke. The

hammer only needs enough pressure to engage the SHOCKS Active Vibration Control

® system.

Applying too much pressure will not make the tool drill or chip faster and the SHOCKS Active

Vibration Control® system will not engage.

Inserting and Removing SDS Max® Accessories (Fig. 5)

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool

from power source before making any adjustments or removing/installing attachments

or accessories.

1. Pull back the locking sleeve (P) and insert the bit shank. The bit shank must be clean and

slightly lubricated.

2. Turn the bit slightly until the sleeve snaps back into position.

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 appli cations. 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.

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 ( )

D25721, D25762

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

and masonry operations.

CHIPPING MODE ( )

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 ( )

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 under Repairs Maintenance).

OPERATION

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: 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.

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.

Hammerdrilling with a Solid Bit (Fig. 1, 6)

(D25721, D25762)

1. Set the mode selector (F) to hammerdrilling mode.

2. Move the torque control lever (V) to Setting 1 (R).

3. Set the speed and impact control dial (G).

4. Insert the appropriate drill bit.

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

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

7. Place the drill bit on that mark and depress the trigger switch.

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

Control).

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

before unplugging.

Hammerdrilling with a Core Bit (Fig. 1, 6)

(D25721, D25762)

CAUTION: Do not use a core bit for hammerdrilling wood. Personal injury and damage to tool

may result.

1. Set the mode selector (F) to hammerdrilling mode.

2. Move the torque control lever (V) to Setting 2 (S).

3. Turn the speed and impact control dial (G) to a slow speed position.

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

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).

3. Insert the appropriate chisel and rotate it by hand to lock it into the desired position.

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).

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.

Motor Brushes

DEWALT uses an advanced brush system which automatically stops the drill when the brushes

wear out. This prevents serious damage to the motor. New brush assemblies are available at

authorized DEWALT service centers. Always use identical replacement parts.

Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To

minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing

this.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts

of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth

dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse

any part of the tool into a liquid.

Lubrication

Your tool was properly lubricated before leaving the factory. In two to six months, depending upon

use, take or send your tool to an authorized service center for a complete cleaning, inspection and

lubrication. Tools used constantly on production jobs will need relubrication more often. Also, tools

“out of service” for long periods should be relubricated before being put back to work.

Avertissements de sécurité généraux pour les outils

électriques

AVERTISSEMENT ! Lire tous les avertissements de sécurité et toutes les directives.

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

électrique, un incendie et/ou une blessure grave.

CONSERVER TOUS LES AVERTISSEMENTS ET TOUTES LES

DIRECTIVES POUR UN USAGE ULTÉRIEUR

Le terme « outil électrique » cité dans les avertissements se rapporte à votre outil électrique à

alimentation sur secteur (avec fil) ou par piles (sans fil).

1) SÉCURITÉ DU LIEU DE TRAVAIL

a) Tenir l’aire de travail propre et bien éclairée. Les lieux encombrés ou sombres sont

propices aux accidents.

b) Ne pas faire fonctionner d’outils électriques dans un milieu déflagrant, tel qu’en

présence de liquides, de gaz ou de poussières inflammables. Les outils électriques

produisent des étincelles qui pourraient enflammer la poussière ou les vapeurs.

c) Éloigner les enfants et les personnes à proximité pendant l’utilisation d’un outil

électrique. Une distraction pourrait en faire perdre la maîtrise à l’utilisateur.

2) SÉCURITÉ EN MATIÈRE D’ÉLECTRICITÉ

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

la fiche d’aucune façon. Ne jamais utiliser de fiche d’adaptation avec un outil

électrique mis à la terre. Le risque de choc électrique sera réduit par l’utilisation de fiches

non modifiées correspondant à la prise.

b) Éviter tout contact physique avec des surfaces mises à la terre comme des tuyaux,

des radiateurs, des cuisinières et des réfrigérateurs. Le risque de choc électrique est

plus élevé si votre corps est mis à la terre.

c) Ne pas exposer les outils électriques à la pluie ou à l’humidité. La pénétration de l’eau

dans un outil électrique augmente le risque de choc électrique.

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

transporter, tirer ou débrancher un outil électrique. Tenir le cordon éloigné de

la chaleur, de l’huile, des bords tranchants et des pièces mobiles. Les cordons

endommagés ou enchevêtrés augmentent les risques de choc électrique.

e) Pour l’utilisation d’un outil électrique à l’extérieur, se servir d’une rallonge

convenant à cette application. L’utilisation d’une rallonge conçue pour l’extérieur réduira

les risques de choc électrique.

f) S’il est impossible d’éviter l’utilisation d’un outil électrique dans un endroit

humide, brancher l’outil dans une prise ou sur un circuit d’alimentation dotés d’un

disjoncteur de fuite à la terre (GFCI). L’utilisation de ce type de disjoncteur réduit les

risques de choc électrique.

3) SÉCURITÉ PERSONNELLE

a) Être vigilant, surveiller le travail effectué et faire preuve de jugement lorsqu’un outil

électrique est utilisé. Ne pas utiliser d’outil électrique en cas de fatigue ou sous

l’influence de drogues, d’alcool ou de médicaments. Un simple moment d’inattention

en utilisant un outil électrique peut entraîner des blessures corporelles graves.

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

oculaire. L’utilisation d’équipements de protection comme un masque antipoussière, des

chaussures antidérapantes, un casque de sécurité ou des protecteurs auditifs lorsque la

situation le requiert réduira les risques de blessures corporelles.

c) Empêcher les démarrages intempestifs. S’assurer que l’interrupteur se trouve à la

position d’arrêt avant de relier l’outil à une source d’alimentation et/ou d’insérer un

bloc-piles, de ramasser ou de transporter l’outil. Transporter un outil électrique alors

que le doigt repose sur l’interrupteur ou brancher un outil électrique dont l’interrupteur est à

la position de marche risque de provoquer un accident.

d) Retirer toute clé de réglage ou clé avant de démarrer l’outil. Une clé ou une clé de

réglage attachée à une partie pivotante de l’outil électrique peut provoquer des blessures

corporelles.

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

mieux maîtriser l’outil électrique dans les situations imprévues.

f) S’habiller de manière appropriée. Ne pas porter de vêtements amples ni de bijoux.

Garder les cheveux, les vêtements et les gants à l’écart des pièces mobiles. Les

vêtements amples, les bijoux ou les cheveux longs risquent de rester coincés dans les pièces

mobiles.

g) Si des composants sont fournis pour le raccordement de dispositifs de dépoussiérage

et de ramassage, s’assurer que ceux-ci sont bien raccordés et utilisés. L’utilisation

d’un dispositif de dépoussiérage peut réduire les dangers engendrés par les poussières.

4) UTILISATION ET ENTRETIEN D’UN OUTIL ÉLECTRIQUE

a) Ne pas forcer un outil électrique. Utiliser l’outil électrique approprié à l’application.

L’outil électrique approprié effectuera un meilleur travail, de façon plus sûre et à la vitesse

pour laquelle il a été conçu.

b) Ne pas utiliser un outil électrique dont l’interrupteur est défectueux. Tout outil

électrique dont l’interrupteur est défectueux est dangereux et doit être réparé.

c) Débrancher la fiche de la source d’alimentation et/ou du bloc-piles de l’outil

électrique avant de faire tout réglage ou changement d’accessoire ou avant de

ranger l’outil. Ces mesures préventives réduisent les risques de démarrage accidentel de

l’outil électrique.

d) Ranger les outils électriques hors de la portée des enfants et ne permettre à

aucune personne n’étant pas familière avec un outil électrique ou son mode

d’emploi d’utiliser cet outil. Les outils électriques deviennent dangereux entre les mains

d’utilisateurs inexpérimentés.

e) Entretien des outils électriques. Vérifier si les pièces mobiles sont mal alignées ou

coincées, si des pièces sont brisées ou présentent toute autre condition susceptible

de nuire au bon fonctionnement de l’outil électrique. En cas de dommage, faire

réparer l’outil électrique avant toute nouvelle utilisation. Beaucoup d’accidents sont

causés par des outils électriques mal entretenus.

f) S’assurer que les outils de coupe sont aiguisés et propres. Les outils de coupe bien

entretenus et affûtés sont moins susceptibles de se coincer et sont plus faciles à maîtriser.

g) Utiliser l’outil électrique, les accessoires, les forets, etc. conformément aux

présentes directives en tenant compte des conditions de travail et du travail à

effectuer. L’utilisation d’un outil électrique pour toute opération autre que celle pour laquelle

il a été conçu est dangereuse.

5) RÉPARATION

a) Faire réparer l’outil électrique par un réparateur professionnel en n’utilisant que

des pièces de rechange identiques. Cela permettra de maintenir une utilisation sécuritaire

de l’outil électrique.

Consignes de sécurité additionnelles propres aux marteaux

rotatifs

• Porter un dispositif de protection auditif. Le bruit en résultant pourrait occasionner une

perte de l’acuité auditive.

• Utiliser la/les poignée(s) auxiliaire(s) si fournie(s) avec l’outil. Une perte de contrôle de

l’outil pourrait occasionner des dommages corporels.

• Tenir l’outil électrique par les surfaces isolées prévues à cet effet pendant toute

utilisation où l’organe de coupe pourrait entrer en contact avec des fils électriques

cachés ou son propre cordon. Tout contact de l’organe de coupe avec un fil sous tension

mettra les parties métalliques exposées de l’outil électrique sous tension et électrocutera

l’utilisateur.

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

une surface stable. Tenir la pièce à la main ou contre son corps offre une stabilité insuffisante

qui pourrait vous en faire perdre le contrôle.

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

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

oculaires permanents. Porter un masque anti-poussières ou un appareil de protection des voies

respiratoires pour toute application productrice de poussières. Une protection auditive peut

s’avérer nécessaire pour la plupart des applications.

• Maintenir systématiquement l’outil fermement. Ne pas tenter d’utiliser cet outil

sans le maintenir à deux mains. Il est recommandé d’utiliser systématiquement la poignée

latérale. Le fait d’utiliser cet outil à une main pourra vous en faire perdre le contrôle. Traverser ou

rencontrer des matériaux durs comme les armatures peut aussi s’avérer dangereux. Resserrer

soigneusement la poignée latérale avant toute utilisation.

• Ne pas utiliser cet outil pendant des périodes de temps prolongées. Les vibrations

causées 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 fréquentes.

• Ne pas remettre à neuf les forets soi-même. La remise à neuf de tout burin doit être

effectuée par un spécialiste agréé. Tout burin remis à neuf incorrectement pose des risques de

dommages corporels.

• Porter des gants lors de l’utilisation de l’outil ou le changement de mèche. Les parties

métalliques accessibles de l’outil et des mèches/forets pourraient s’avérer brûlantes lors de

l’utilisation. De petits débris de matériau pourraient aussi blesser les mains nues.

• Attendre systématiquement l’arrêt complet de la mèche/foret avant de déposer l’outil

où que ce soit. Des forets/mèches en rotation posent des risques de dommages corporels.

• Ne pas donner des coups de marteau sur des forets/mèches coincés pour les déloger.

Des fragments de métal ou de matériau pourraient être éjectés et causer des dommages

corporels.

• Maintenir le cordon d’alimentation à l’écart d’une mèche en rotation. Ne pas enrouler

le cordon autour d’une partie quelconque de votre corps. Un cordon électrique enroulé

autour d’une mèche en rotation pose des risques de dommages corporels et de perdre le

contrôle de l’outil.

• Prendre des précautions à proximité des évents, car ils cachent des pièces mobiles.

Vêtements amples, bijoux ou cheveux longs risquent de rester coincés dans ces pièces mobiles.

• Pour la sécurité de l’utilisateur, utiliser une rallonge de calibre adéquat (AWG,

American Wire Gauge [calibrage américain normalisé des fils électriques]). Plus le

calibre est petit, et plus sa capacité est grande. Un calibre 16, par exemple, a une capacité

supérieure à un calibre18. L’usage d’une rallonge de calibre insuffisant causera une chute de

tension qui entraînera perte de puissance et surchauffe. Si plus d’une rallonge est utilisée pour

obtenir une certaine longueur, s’assurer que chaque rallonge présente au moins le calibre de

fil minimum. Le tableau ci-dessous illustre les calibres à utiliser selon la longueur de rallonge

et l’intensité nominale indiquée sur la plaque signalétique. 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. Utiliser aussi un masque antipoussières si

la découpe doit en produire beaucoup. PORTER SYSTÉMATIQUEMENT UN ÉQUIPEMENT DE

SÉCURITÉ HOMOLOGUÉ:

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

• Protection auditive ANSI S12.6 (S3.19);

• Protection des voies respiratoires NIOSH/OSHA/MSHA.

AVERTISSEMENT : les scies, meules, ponceuses, perceuses ou autres outils de construction

peuvent produire des poussières contenant des produits chimiques reconnus par l’État californien

pour causer cancers, malformations congénitales ou être nocifs au système reproducteur. Parmi

ces produits chimiques, on retrouve:

• Le plomb dans les peintures à base de plomb;

• La silice cristallisée dans les briques et le ciment, ou autres produits de maçonnerie; et

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

Le risque associé à de telles expositions varie selon la fréquence à laquelle on effectue ces travaux.

Pour réduire toute exposition à ces produits: travailler dans un endroit bien aéré, en utilisant du
