General Safety Rules – For All Tools

WARNING! Read and understand all instructions.

Failure to follow all instructions listed below may result

English

in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

• Keep your work area clean and well lit. Cluttered benches

and dark areas invite accidents.

• Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or

fumes.

• Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically

malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 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. If the plug does not fit fully in the outlet, reverse the plug. If 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. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Minimum Gauge for Cord Sets

Volts Total Length of Cord in Feet

120V 0-25 26-50 51-100 101-150 240V 0-50 51-100 101-200 201-300

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication.

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

• Dress properly. Do not wear loose clothing or jewelry.

Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair

can be caught in moving parts. Air vents often cover moving parts and should also be avoided.

• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

• 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 tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained

tools.

• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

SERVICE

• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified

personnel could result in a risk of injury.

• When servicing a tool, use only identical replacement

parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow

maintenance instructions may create a risk of electric shock or injury.

Additional Specific Safety Instructions for Grinders

• Check that the grinding wheel backing flange has a yellow rubber ring (F) installed, see Figure 1. Replace rubber ring if missing, damaged or worn. See page 11 for details regarding proper accessory installation.

English

WARNING: The grinding wheel or accessory may loosen during coast-down of the tool when shut off if rubber ring is missing or damaged. If grinding wheel or accessory loosens, it

may dismount from the machine and may cause serious personal injury.

• Always use proper guard with grinding wheel. A guard

protects operator from broken wheel fragments and wheel

English

contact.

• Accessories must be rated for at least the speed recom-

mended on the tool warning label. Wheels and other

accessories running over rated speed can fly apart and cause injury. Accessory ratings must be above listed minimum wheel 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.

• Do not use Type 11 (flaring cup) wheels on this tool. Using

inappropriate accessories can result in injury.

• 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.

• When starting the tool with a new or replacement wheel,

or a new or replacement wire brush installed, hold the tool in a well protected area and let it run for one minute. If the

wheel has an undetected crack or flaw, it should burst in less than one minute. If the wire brush has loose wires, they will be detected. 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 cutting and/or grinding. Sparks may cause burns or start fires.

• Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times.

• Never cut into area that may contain electrical wiring or

piping. Serious injury may result.

• Clean out your tool often, especially after heavy use. Dust

and grit containing metal 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 the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

• Direct the Dust Ejection System

away from operator and

coworkers. Serious injury may result (Fig. 1, K).

• The label on your tool may include the following symbols. The

symbols and their definitions are as follows:

V ..................volts A ............ amperes

Hz ................hertz W ........... watts

min .............. minutes

...........direct current

......... alternating current

o .......... no load speed

................Class I Construction ........... earthing terminal

.................... .............. per minute

Causes and Operator Prevention of Kickback

• Kickback is a sudden reaction to a pinched, bound or misaligned wheel, wire brush or flap disc causing an uncontrolled cut-off tool to lift up and out of the workpiece toward the operator.

• When the wheel is pinched or bound tightly by the workpiece, the wheel stalls and the motor reaction drives the unit rapidly back toward or away from the operator.

• Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip with both hands on the unit and

position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the

operator, if proper precautions are taken.

• When wheel is binding, or when interrupting a cut for any

reason, release the trigger and hold the unit motionless in the material until the wheel comes to a complete stop. Never attempt to remove the unit from the work or pull the unit backward while the wheel is in motion or kickback may occur. Investigate and take corrective actions

to eliminate the cause of wheel binding.

• When restarting a cut-off accessory in the workpiece, check that the wheel is not engaged into the material. If wheel is binding, it may walk up or kickback from the workpiece as the tool is restarted.

• Support large panels to minimize the risk of wheel pinching and kickback. Large panels tend to sag under their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

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: 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.

WARNING: Always use eye protection. All users and bystand-

ers must wear eye protection that conforms to ANSI Z87.1.

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.

WARNING: Use of this tool can generate and/or disburse 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.

English

CAUTION: Use extra care when working into a corner because

a sudden, sharp movement of the grinder may be experienced when the wheel or other accessory contacts a secondary surface or a surface edge.

the threaded clamp nut. If a thin wheel is installed with the pilot on the clamp nut against the wheel, it will spin because the height of the pilot prevents the clamp nut from holding the wheel.

SURFACE GRINDING WITH GRINDING WHEELS

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3. Maintain a 20˚ to 30˚ angle between the tool and work surface.

4. Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

EDGE GRINDING WITH GRINDING WHEELS

CAUTION: Wheels used for cutting and

edge grinding may break if they bend or twist while the tool is being used to do cut-off work or deep grinding. To reduce the risk of serious injury, limit the use of these wheels with a standard Type 27 guard to shallow cutting and notching [less than 1/2" (12.7 mm) in depth]. The open side of the guard must be positioned away from the operator. For deeper cutting with a Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart on page 8 for more information. Type 1 guards are available at extra cost from your local dealer or authorized service center.

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

20˚-30˚

3. Position yourself so that the open-underside of the wheel is facing away from you.

4. Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage. Edge grinding wheels are not designed to withstand side pressures caused by bending.

5. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before laying it down.

WARNING: Do not use edge grinding/cutting wheels for surface

grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result.

SURFACE FINISHING WITH SANDING FLAP DISCS

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed.

3. Maintain a 5˚ to 10˚ angle between the tool and work surface.

4. Continuously move the tool in a forward and backward motion to avoid creating gouges in the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

MOUNTING SANDING BACKING PADS

English

5˚-10˚

CAUTION: Proper guard must be reinstalled for grinding wheel,

sanding flap disc, wire brush or wire wheel applications after sanding applications are complete.

1. Place or appropriately thread backing pad (O) on the spindle.

2. Place the sanding disc (P) on the backing pad.

3. While depressing spindle lock, thread clamp nut (H) on

English

spindle, piloting the raised hub on the clamp nut into the center of san ding disc and backing pad.

4. Tighten the clamp nut by hand. Then depress the spindle lock button while turning the sanding disc until the sanding disc and clamp nut are snug.

5. To remove the wheel, grasp and turn the backing pad and sanding pad while depressing the spindle lock button.

USING SANDING BACKING PADS

Choose the proper grit sandpaper for your application. Sandpaper is available in various grits. Coarse grits yield faster material removal rates and a rougher finish. Finer grits yield slower material removal and a smoother finish.

Begin with coarse grit discs for fast, rough material removal. Move to a medium grit paper and finish with a fine grit disc for optimal finish.

Coarse 16 - 30 grit Medium 36 - 80 grit Fine Finishing 100 - 120 grit Very Fine Finishing 150 - 180 grit

1. Allow the tool to reach full speed before touching tool to the work surface.

2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed.

3. Maintain a 5˚ to 15˚ angle between the tool and work surface. The san ding disc should contact approximately one inch of work surface.

4. Move the tool constantly in a straight line to prevent burning and swirling of work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

5˚-15˚

Mounting and Using Wire Brushes and Wire Wheels

Wire cup brushes or wire wheels screw directly on the grinder

spindle without the use of flanges. Use only wire brushes or wheels provided with a 5/8"-11 threaded hub. A Type 27 guard is required when using wire brushes and wheels.

CAUTION: Wear work gloves when handling wire brushes

and wheels. They can become sharp.

CAUTION: Wheel or brush must not touch guard when mounted

or while in use. Undetectable damage could occur to the accessory, causing wires to fragment from accessory wheel or cup.

MOUNTING WIRE BRUSHES AND WIRE WHEELS

1. Thread the wheel on the spindle by hand.

2. Depress spindle lock button and use a wrench on the hub of the wire wheel or brush to tighten the wheel.

3. To remove the wheel, reverse the above procedure.

CAUTION: Failure to properly seat the wheel hub before turning

the tool on may result in damage to tool or wheel.

USING WIRE CUP BRUSHES AND WIRE WHEELS

Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Material removal rate is greatest when the tool operates at high speed.

3. Maintain a 5˚ to 10˚ angle between the tool and work surface for wire cup brushes.

4. Maintain contact between the edge of the wheel and the work surface with wire wheels.

5. Continuously move the tool in a forward and backward motion to avoid creating gouges in the work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface.

6. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before setting it down.

CAUTION: Use extra care when working over an edge, as a

sudden sharp movement of grinder may be experienced.

5˚-10˚

Mounting and Using Cutting (Type 1) Wheels

Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal and concrete use are available. Diamond blades for concrete cutting can also be used. NOTE: All grinders that use Type 1 wheels use the quick-change backing flange (G1).

WARNING: A closed, 2-sided cutting wheel guard is not included

with this tool and is re quired when using cutting wheels. Fail ure to use proper flange and guard can re sult in injury resulting from wheel breakage and wheel contact. See page 8 for more information.

MOUNTING CLOSED (TYPE 1) GUARD

1. Open the guard latch (J). Align the

lugs (K) on the guard with the slots (L) on the gear case.

2. Push the guard down until the

guard lug engages and rotates freely in the groove on the gear case hub.

3. Rotate guard (D) into desired

working position. The guard body should be positioned between the spindle and the operator to provide maximum operator protection.

4. Close the guard latch to secure the

guard on the gear case cover. You should be unable to rotate the

English

guard by hand when the latch is in closed position. If rotation is possible, tighten the adjusting screw (M) with clamp lever in the closed position. Do not operate grinder with a loose guard or clamp lever in open position.

5. To remove the guard, open the guard latch, rotate the guard so

English

that the arrows are aligned and pull up on the guard.

NOTE: If, after a period of time, the guard becomes loose, tighten the adjusting screw (M) with the clamp lever in the closed position.

CAUTION: Do not tighten adjusting screw with clamp lever in

open position. Undetectable damage to guard or mounting hub may result.

MOUNTING CUTTING WHEELS

CAUTION: Turn off and unplug the tool before making any adjustments or removing or installing attachments or accessories. Before reconnecting the tool, turn the switch on and off as previously described to ensure that the tool is off.

CAUTION: Matching diameter backing flange and threaded

clamp nut (included with tool) must be used for cutting wheels.

1. Place the unthreaded backing flange on spindle with the raised

section (pilot) facing up. The raised section (pilot) on the backing flange will be against the wheel when the wheel is installed.

2. Place the wheel on the quick-change backing

flange, centering the wheel on the raised section (pilot).

3. Install the threaded clamp nut with the raised

section (pilot) facing away from the wheel.

4. Depress the spindle lock button and tighten

clamp nut with a wrench.

5. To remove the wheel, grasp and turn while depressing the spindle lock button.

USING CUTTING WHEELS

WARNING: Do not use edge grinding/ cutting wheels for surface

grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result.

1. Allow tool to reach full speed before touching tool to work surface.

2. Apply minimum pressure to work surface, allowing tool to operate at high speed. Cutting rate is greatest when the tool operates at high speed.

3. Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage.

4. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before setting it down.

MAINTENANCE

Cleaning

WARNING: Blowing dust and grit out of motor and switch actuator using clean, dry compressed air is a necessary regular maintenance procedure. Dust and grit containing metal particles often accumulate on interior surfaces and could create an electrical shock or electrocution if not frequently cleaned out. It is recommended that a ground fault circuit interrupter (GFCI) is utilized to further protect the user from electric shock resulting from the accumulation of conductive particles. If the tool is deactivated by the GFCI, unplug the tool and

check and clean the tool before resetting the GFCI. ALWAYS WEAR SAFETY GLASSES when cleaning or using this tool.

CAUTION: Never use solvents or other harsh chemicals

for cleaning the non-metallic parts of the tool. Use a clean, dry cloth only.

Règles générales de sécurité pour tous les outils

AVERTISSEMENT! Lire et assimiler toutes les

directives. Le non-respect des directives indiquées

ci-dessous peut entraîner des risques de choc électrique, d’incendie ou de blessures corporelles graves.

CONSERVER CES DIRECTIVES

ESPACE DE TRAVAIL

• Tenir l’espace de travail propre et bien éclairé. Les établis

encombrés et les endroits sombres sont souvent propices aux accidents.

• Ne pas faire fonctionner d’outils électriques dans un milieu

déflagrant, par exemple en présence de liquides, de gaz ou

Français

de poussières inflammables. Les outils électriques produisent des étincelles qui peuvent enflammer la poussière ou les vapeurs.

• Éloigner les curieux, les enfants et les visiteurs lors de l’utilisation d’un outil électrique. Une distraction pourrait vous en faire perdre la maîtrise.

SÉCURITÉ EN MATIÈRE D’ÉLECTRICITÉ

• Les outils mis à la terre doivent être branchés dans une prise correctement installée et mise à la terre tel que l’indiquent les codes et règlements en vigueur. Ne jamais retirer la broche de mise à la terre ou modifier la prise en aucune façon. Ne pas utiliser de fiche d’adaptation. Consulter un électricien qualifié s’il y a un doute en ce qui concerne la mise à la terre de la prise. En cas de défaillance électrique

EWALT,

ou de bris de l’outil, la mise à la terre procure un chemin de faible résistance au courant afin de réduire les risques de choc électrique. Ne s’applique qu’aux outils de classe I (mis à la

terre).

• Les outils à double isolation sont dotés d’une fiche polarisée (une lame de contact est plus large que l’autre). Elle ne se branchera que d’une seule façon dans une prise de courant polarisée. Si la fiche ne s’insère pas totalement dans la prise de courant, l’inverser. Si elle ne s’insère toujours pas dans la prise, demander à un électricien qualifié d’installer une prise polarisée. Ne pas remplacer la fiche. La

double isolation d’alimentation muni d’une fiche à trois fils avec mise à la terre et un bloc d’alimentation avec mise à la terre. Ne s’applique

qu’aux outils de classe II (à double isolation).

• 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

lorsque le corps est mis à la terre.

• Ne pas exposer les outils électriques à la pluie ou à un environnement humide. La pénétration de l’eau dans un outil électrique augmente le risque de choc électrique.

• Ne pas utiliser le cordon de façon abusive. Ne pas utiliser

le cordon pour transporter l’outil ni tirer dessus pour le débrancher de la prise de courant. Tenir le cordon éloigné de la chaleur, de l’huile, des bords tranchants et des pièces mobiles. Remplacer immédiatement tout cordon endommagé. Un cordon endommagé augmente le risque de

choc électrique.

• Lorsqu’un outil électrique est utilisé à l’extérieur, utiliser

une rallonge pour l’extérieur portant la mention « W-A » ou « W ». Ces rallonges sont classées pour un usage extérieur, ce

qui réduit le risque de choc électrique. Lorsqu’une rallonge est utilisée, s’assurer d’utiliser un calibre suffisamment élevé pour

élimine la nécessité d’utiliser un cordon
