GENERAL SAFETY RULES

WARNING!

Read and understand all instructions. Failure to follow all instructions listed below may

result 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

• 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.

• 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.

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 and clothing away

from moving parts. Loose clothing, jewelry, or long hair can be caught in moving parts.

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

switch or plugging in tools that have the switch on invites accidents.

• Remove adjusting keys or wrenches before turning the tool on. A wrench or key that is left attached to a

rotating part of the tool may result in personal 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 a loss of control.

• Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at

the rate for which it is designed.

• Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is

dangerous and must be repaired.

• Disconnect the plug from the power source before making any adjustments, changing accessories, or

storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally.

• Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of

untrained users.

• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting

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

• Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may

affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by

poorly maintained tools.

• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be

suitable 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 sec-

tion of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk

of electric shock or injury.

SPECIFIC SAFETY RULES

• Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments.

Always position the guard so that as much of the exposed disc as possible is pointing away from you.

• Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and

other accessories running over rated speed can fly apart and cause injury.

• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may con-

tact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live"

and shock the operator.

ADDITIONAL SAFETY RULES

• ALWAYS WEAR EYE PROTECTION.

• WEAR EAR PROTECTION. NOISE LEVEL MAY BE AMPLIFIED WHEN GRINDING IN ENCLOSED SPACES.

• KEEP GUARDS IN PLACE.

• Use only accessories having a maximum operating speed at least as high as the speed specified in the warn-

ing on the tool’s label.

• Before using, inspect recommended accessory for cracks or flaws. If such a crack or flaw is evident, discard

the accessory. The accessory should also be inspected whenever you think the tool may have been dropped.

• When starting the tool (with a new or replacement wheel or brush installed) hold the tool in a well protect-

ed area and let it run for one minute. If the wheel or brush has an undetected crack or flaw, it should burst or

separate in less than one minute. Never start the tool with a person in line with the accessory. This includes

the operator.

• In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect

the wheel.

• ALWAYS USE GUARDS with grinding wheels and wire brushes. Always position the guard so that as much of

the exposed wheel or wire brush as possible is pointing away from you.

• Clean your tool out periodically.

• Do not use Type 1 abrasive or diamond wheels without proper guard.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activ-

ities 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 expo-

sure 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.

AVERTISSEMENT! Lire et comprendre toutes les directives. Le non-respect de toutes les directives suivantes

présente des risques de secousses électriques, d'incendie ou de blessures graves.

CONSERVER CES MESURES

ZONE DE TRAVAIL

•S'assurer que la zone de travail est propre et bien éclairée. Des établis encombrés et des endroits sombres

présentent des risques d'accidents.

•Ne pas utiliser des outils électriques en présence de vapeurs explosives (comme celles dégagées par des

liquides, des gaz ou des poussières inflammables). Les étincelles générées par le moteur des outils

électriques peuvent enflammer les poussières ou les vapeurs.

• Éloigner les curieux, les enfants et les visiteurs de la zone de travail lorsqu'on utilise un outil électrique.

Une distraction peut entraîner la perte de maîtrise de l'outil.

MESURES DE SÉCURITÉ RELATIVES À L'ÉLECTRICITÉ

•Les outils à double isolation comportent une fiche polarisée (une lame plus large que l'autre). La fiche

n'entre que d'une façon dans une prise polarisée. Lorsque la fiche n'entre pas à fond dans la prise,

essayer de nouveau après avoir inversé les broches de la fiche. Si la fiche n'entre toujours pas dans la

prise, communiquer avec un électricien certifié afin de faire installer une prise polarisée. Ne modifier en

aucune façon la fiche. La double isolation élimine le besoin d'un cordon trifilaire mis à la terre et d'un

système d'alimentation mis à la terre.

•Éviter de toucher à des surfaces mises à la terre comme des tuyaux, des radiateurs, des cuisinières et des

réfrigérateurs. Les risques de secousses électriques sont plus élevés si le corps de l'utilisateur est mis à la

terre.

•Protéger les outils électriques de la pluie ou des conditions mouillées. Une infiltration d'eau dans l'outil

augmente les risques de secousses électriques.

•Manipuler le cordon avec soin. Ne jamais se servir du cordon afin de transporter l'outil ni tirer sur le

cordon pour débrancher l'outil. Éloigner le cordon des sources de chaleur, des flaques d'huile, des arêtes

tranchantes et des pièces mobiles. Remplacer immédiatement les cordons endommagés. Les cordons

endommagés augmentent les risques de secousses électriques.

•Lorsqu'on utilise un outil électrique à l'extérieur, se servir d'un cordon de rallonge prévu pour l'extérieur,

portant la mention “W-A” ou “W”. Ces cordons sont conçus pour servir à l'extérieur et minimisent les

risques de secousses électriques. Lorsqu'on se sert d'un cordon de rallonge, s'assurer qu'il est de calibre

approprié pour la tension nécessaire au fonctionnement de l'outil. L'utilisation d'un cordon de calibre

inférieur occasionne une baisse de tension entraînant une perte de puissance et la surchauffe. Le tableau

suivant indique le calibre approprié selon la longueur du cordon et les mentions de la plaque signalétique de

l'outil. En cas de doute, utiliser un cordon de calibre supérieur. Le chiffre indiquant le calibre est inversement

proportionnel au calibre du cordon.

SÉCURITÉ PERSONNELLE

•Demeurer vigilant, prendre soin et faire preuve de jugement lorsqu'on utilise un outil électrique. Ne pas

s'en servir lorsqu'on est fatigué ou affaibli par des drogues, de l'alcool ou des médicaments. De graves

GUIDE D’UTILISATION

EXTENSION CORD

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 table

below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use

the next heavier gage. The smaller the gage number, the heavier the cord.

MOTOR

Your tool is powered by a Black & Decker specified motor. Be sure your power supply agrees with the name-

plate marking. A marking of 120 volts, 50/60 Hz or 120 volts, AC only means that the tool is designed to oper-

ate on normal 120 volt house current. Voltage decrease of more that 10% will cause loss of power and over-

heating. All Black & Decker tools are factory tested. If this tool does not run, check the power supply.

AUXILIARY HANDLE (G750 / FIG. 1)

A two position auxiliary handle (5) is furnished with your grinder and can be screwed into either side of the

grinder housing. This handle SHOULD BE USED AT ALL TIMES to maintain complete control of the tool.

AUXILIARY HANDLE (G850 / FIG. 1A)

A three position auxiliary handle (5) is furnished with your grinder and can be screwed into either side of the

grinder housing as well as into the top. This handle SHOULD BE USED AT ALL TIMES to maintain complete

control of the tool.

STARTING THE TOOL (G750)

To start the tool, slide the ON/OFF switch forward (1). For continuous operation, slide the switch fully for-

ward (2). To stop the tool, release the ON/OFF switch. To stop the tool while running in continuous mode,

press the rearward part of the switch.

NOTE: Do not switch the tool on or off while under load conditions. Allow the grinder to run up to full speed

before touching the surface to be ground. Lift the tool from the surface before turning the tool off.

STARTING THE TOOL (G850)

To switch your angle grinder on, depress the trigger switch (1). The angle grinder will stop when the trigger

switch is released. For continuous operation depress the lock-on button (2) while the trigger switch is

depressed. Release the trigger switch prior to releasing the lock-on button. To stop your angle grinder when

operation is continuous depress the trigger switch again and release.

OVERLOAD

Overloading will cause damage to the motor of your angle grinder. This can happen if your angle grinder is

subjected to heavy use for prolonged periods of time. Do not in any circumstances, attempt to exert too much

pressure on your angle grinder to speed up your work. The abrasive discs operate more efficiently when light

pressure is exerted, thus avoiding a drop in the speed of your angle grinder.

GRINDING AND WIRE BRUSHING

ATTACHING THE WHEEL GUARD (FIG.2)

TURN OFF AND UNPLUG THE TOOL. NEVER GRIND OR BRUSH WITHOUT GUARD IN PLACE.

Place the angle grinder on a table, spindle up. Align the lug with the slot in the bracket. Press the guard down

and turn it in the direction of the arrow. NOTE: The guard locking pin prevents the guard from coming loose.

FITTING DEPRESSED CENTER WHEELS (FIGS. 3,4,5,6)

TURN OFF AND UNPLUG THE TOOL. CAUTION: Never use any depressed-center wheels without the

proper guard.

1. Ensure that the guard is fitted properly. Place the inner flange (a) in Fig. 3 on the spindle. Ensure that it

is located on the two flats.

2. Place the grinding wheel on the spindle and inner flange (a) in Fig. 4.

3. Fit the threaded outer flange (b) Fig. 5, making sure it is facing in the correct direction for the type of

wheel fitted. For thick grinding wheels, the flange ( b) is fitted with the raised portion facing towards the wheel.

For thin grinding wheels, the flange (b) is fitted with the inner portion facing away from the wheel.

4. Press in the spindle lock button and rotate the spindle until it locks. Keeping the lock button pressed in,

tighten the outer flange with the spanner wrench provided as shown in Fig. 6.

5. When using a depressed-center wheel, hold the tool so that an angle of approximately 30° exists between

the wheel and the work.

WARNING:

Check rated speed on depressed-center wheel. Never use a wheel with rated speed lower than

the speed on the nameplate of the tool.

FITTING WIRE CUP BRUSHES

Wire cup brushs screw directly on the spindle of the machine without the use of flanges. When using wire

brushes, thread firmly on spindle by hand.

SANDING

REMOVING THE WHEEL GUARD (FIG. 7 SANDING ONLY)

TURN OFF AND UNPLUG THE TOOL.

NOTE: TO PREVENT LOSS OF CONTROL, DO NOT SET TOOL DOWN UNTIL ACCESSORY HAS COM-

PLETELY STOPPED TURNING.

As shown in Fig. 7, place the grinder on a table, spindle up. Rotate the guard in the direction of the arrow

until it stops. Use a small screwdriver to depress the locking pin in the slot. While holding the locking pin down

with the screwdriver, turn the guard slightly in the direction of the arrow to keep the locking pin depressed.

Remove the screwdriver and continue to turn the guard until it is released.

PRECAUTIONS TO TAKE WHEN SANDING PAINT

1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the

contaminated dust. The greatest danger of lead poisoning is to children and pregnant women.

2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we recommend

the following precautions when sanding any paint:

PERSONAL SAFETY

1. No children or pregnant women should enter the work area where the paint sanding is being done until all

cleanup is completed.

2. A dustmask or respirator should be worn by all persons entering the work area. The filter should be replaced

daily or whenever the wearer has difficulty breathing.

NOTE: ONLY THOSE DUSTMASKS SUITABLE FOR WORKING WITH LEAD PAINT DUST AND

FUMES SHOULD BE USED. ORDINARY PAINTING MASKS DO NOT OFFER THIS

PROTECTION. SEE YOUR LOCAL HARDWARE DEALER FOR THE NIOSH APPROVED PROPER

MASK.

ENVIRONMENTAL SAFETY

1. Paint should be removed in such a manner as to minimize the amount of dust generated.

2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness.

3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.

FITTING ABRASIVE DISCS

TURN OFF AND UNPLUG THE TOOL.

Use an abrasive disc with a backing pad for sanding with your angle grinder.

1. Remove the guard.

2. Place the flange, (backing pad and abrasive disc sold separately) and outer flange on the spindle as

shown in Figure 8. Figure 8A shows how to attach an abrasive disc with a rubber backing pad.

3. Tighten the abrasive disc as shown in Figure 9 by depressing the spindle lock button and turning the

abrasive disc by hand.

GENERAL INFORMATION

HELPFUL HINTS

• Hold your angle grinder with one hand on the body and the other hand firmly around the side handle as

shown in Figure 10.

• Always position the guard so that as much of the exposed disc as possible is pointing away from you.

• Be prepared for a stream of sparks when the disc touches the metal.

• Maintain an angle between the disc and work surface (Fig. 11) of approximately 30° when grinding and 10°-

15° when sanding ( Fig. 12) for best tool control, material removal, and minimal loading.

WARNING:

Always wear eye protection while operating this power tool.

TOOL MAINTENANCE

CLEANING: Blowing dust and grit out of the motor housing using compressed air is a necessary maintenance

procedure. Dust and grit containing particles from metal grinding often accumulate on interior surfaces and

could create an electrical shock hazard if not cleaned out.
