Additional power tool safety warnings
Warning! Additional safety warnings Common for Grinding, Sanding, Wire Brushing, Polishing or Abrasive Cutting-Off Operations:

• This power tool is intended to function as a grinder, sander, wire brush, polisher or cut-off tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool.
  Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

• Operations for which the power tool was not designed may create a hazard and cause personal injury.

• Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.

• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.

• Threaded mounting of accessories must match the grinder spindle thread.
  For accessories mounted by flanges, the arbour hole of the accessory must fit the
  locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.

• Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.

• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying
  debris generated by various operations. The dust mask or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

• Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.

• Hold power tool by insulated gripping surfaces only, 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 shock the operator.

• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

• Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.

• Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.

• Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.

• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

• Do not operate the power tool near flammable materials. Sparks could ignite these materials.

• Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Note: The above warning does not apply for power tools specifically designed for use with a liquid system.

Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching.
Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
• Never place your hand near the rotating accessory. Accessory may kickback over your hand.
• Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
• Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

Safety warnings specific for grinding and abrasive cutting-off operations

• Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.

• The grinding surface of centre depressed wheels must be mounted below the plane
  of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected.

• The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect the operator from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.

• Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.

• Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges.

• Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst.

Additional safety warnings specific for abrasive cutting-off operations

• Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Over stressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
• Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you.
• When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
• Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
• Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
• Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

Safety warnings specific for sanding operations

• Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

Safety warnings specific for polishing operations

• Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or trim any loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.

Safety warnings specific for wire brushing operations

• Be aware that wire bristles are thrown by the brush even during ordinary operation.
  Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.

• If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard.
  Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Warning! Contact with or inhalation of dusts arising from sanding/grinding applications may  endanger the health of the operator and possible bystanders. Wear a dust mask specifically designed for protection against dust and fumes and ensure that persons within or entering the work area are also protected.

Safety of others

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.

Residual risks
Additional residual risks may arise when using the tool which may not be included in the enclosed safety warnings. These risks can arise from misuse, prolonged use etc.

• Remove the outer flange (14) and the disc (6).

Surface grinding with grinding discs

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

• 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.

• Maintain a 20˚ to 30˚ angle between the tool and work surface as shown in figure L.

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

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

Edge grinding with grinding discs
Wheels used for cutting and edge grinding may break or kick back if they bend or twist while the tool is being used to do cutoff work or deep grinding.
Edge grinding/ cutting with a Type 27 wheel must be limited to shallow cutting and notching, less than 13 mm in depth when the wheel is new. Reduce the depth of cutting/notching equal to the reduction of the wheel radius as it wears down. Refer to the ‘Grinding and cutting accessory chart’ at the end of ths manual for more information.
Edge grinding/cutting with a Type 41 wheel requires usage of a Type 41 guard.

• Allow the tool to reach full speed before touching the tool to the work surface.
• 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.
• Position yourself so that the openunderside of the wheel is facing away from you.
• 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.
• 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 if the wheel label has forbidden such use because these wheels are not designed for side
pressures encountered with surface grinding. Wheel breakage and serious personal injury may result.

• Maintain a 5˚ to 10˚ angle between the tool and work surface as shown in figure M.
• Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface.
• Remove the tool from work surface before turning tool off.

Using sanding backing pads
Always choose the proper grit sanding discs for your application. Sanding discs are 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.

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

• 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.

• Maintain a 5˚ to 10˚ angle between the tool and work surface as shown in figure N. The sanding disc should contact approximately 25mm of work surface.

• 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.

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

Precautions to take when sanding paint

• 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.

• 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:

• No children or pregnant women should enter the work area where the paint sanding is being done until all clean up is completed.

• A dust mask 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 dust masks 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 proper approved mask.

• NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or smoking.
  Articles of food, drink, or smoking should not be left in the work area where dust would settle on them.

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

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

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

• All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration of the sanding project. Vacuum filter bags should be changed frequently.

• Plastic drop cloths should be gathered up and disposed of along with any dust chips or other removal debris. They should be placed in sealed refuse receptacles and disposed of through regular trash pick-up procedures. During clean up, children and pregnant women should be kept away from the immediate work area.

• All toys, washable furniture and utensils used by children should be washed thoroughly before being used again.

Fitting and using wire brushes and wire wheels
Wire cup brushes or wire wheels screw directly on the grinder spindle without the use of flanges. A Type 27 guard is required when using wire brushes and wheels. Wear work gloves when handling wire brushes and wheels.
They can become sharp. 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.

• Thread the wheel on the spindle by hand.

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

• To remove the wheel, reverse the above procedure. Warning! Failure to properly seat the wheel hub before turning the tool on may result in damage to tool or wheel. Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.
  Note: The same precautions should be taken when wire brushing paint as when sanding paint.

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

• 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.

• Maintain a 5˚ to 10˚ angle between the tool and work surface for wire cup brushes as shown in figure O.

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

• Continuously move the tool in a forward and back 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.

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

Warning! Use extra care when working over an edge, as a sudden sharp movement of grinder may be experienced.
Mounting and using cutting (type 41) 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: A closed, 2-sided Type 41 cutting wheel guard is sold separately and is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact.
Matching diameter backing flange and threaded clamp nut (included with tool) must be used for cutting wheels.

Mounting cutting wheels

• 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.
• Place the wheel on the backing flange, centering the wheel on the raised section (pilot).
• Install the threaded clamp nut with the raised section (pilot) facing away from the wheel.
• Depress the spindle lock button and tighten clamp nut with included wrench (16).
• To remove the wheel, depress the spindle lock button and loosen the threaded clamp nut with included wrench.

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.

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

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

• 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.

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

Use

Warning! Let the tool work at its own pace. Do not overload.

• Be prepared for a stream of sparks when the grinding or cutting disc touches the workpiece.
• Always position the tool in such a way that the guard provides optimum protection from the grinding or cutting disc.

Switching on and off

• To switch the tool on, slide the lock off switch (2) forward.
• To switch the tool off, slide the lock off switch (2) backward.

Warning! Do not switch the tool off while under load.
Warning! Always engage lock off when the tool is not in use.

Hints for optimum use

• Firmly hold the tool with one hand around the side handle and the other hand around the main handle.
• When grinding, always maintain an angle of approx. 20°- 30° between the disc and the workpiece surface.

Maintenance

Your BLACK+DECKER corded/cordless appliance/tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning. Warning! Before performing any maintenance on corded/cordless power tools:

• Switch off and unplug the appliance/tool.
• Or switch off and remove the battery from the appliance/tool if the appliance/tool has a separate battery pack.
• Or run the battery down completely if it is integral and then switch off.
• Unplug the charger before cleaning it. Your charger does not require any maintenance apart from regular cleaning.
• Regularly clean the ventilation slots in your appliance/tool/charger using a soft brush or dry cloth.
• Regularly clean the motor housing using a damp cloth. Do not use any abrasive or solvent-based cleaner.
