SAFETY INSTRUCTIONS FOR POWER TOOLS

When using power tools, always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions before attempting to operate this product. Keep these instructions in a safe place.

WARNING: To reduce the risk of injury, read the instruction manual.

GENERAL 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.

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

SAVE THESE INSTRUCTIONS

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.

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 safety 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 plugging in. Carrying power tools with your finger on the switch or

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

Definitions: Safety Guidelines

The definitions below describe the level of severity for each signal word. Please read the manual and pay attention to these symbols.

DANGER: Indicates an imminently hazardous situation which, if

not avoided, will result in death or serious injury.

WARNING: Indicates a potentially hazardous situation which, if

not avoided, could result in death or serious injury.

CAUTION: Indicates a potentially hazardous situation which, if

not avoided, may result in minor or moderate injury. CAUTION: Used without the safety alert symbol indicates a

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

application. The 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 and in the manner intended for the particular type of power tool, 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.

Electrical Safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate. 240 V AC means your tool will operate on alternating current. As little as 10% lower voltage can cause loss of power and can result in overheating. All DEWALT tools are factory tested; if this tool does not operate, check the power supply. Your DEWALT tool is double insulated, therefore no earth wire is required.

• Young children and the infirm. This appliance is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that they do not play with this appliance.

• Replacement of the supply cord. If the supply cord is damaged, it must be replaced by the manufacturer or an authorised DEWALT Service Centre in order to avoid a hazard.

Extension Cords

CAUTION: Use only extension cords that are approved by the country’s Electrical Authority. Before using extension cords, inspect them for loose or exposed wires, damaged insulation and defective fittings. Replace the cord if necessary.

Additional Specific Safety Rules

• Check that the grinding wheel backing flange has a yellow rubber ring (S) installed, see Figure 1. Replace rubber ring if missing, damaged or worn. See page 8 for details regarding proper accessory installation.

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 contact.

•

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. 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 (DES) away from operator and coworkers.

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

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

Page 6

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 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 sur face edge.

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 tool 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: 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.

5. To remove the wheel, depress the spindle lock button and loosen the threaded clamp nut with a wrench.

NOTE: If the wheel spins after the clamp nut is tightened, check the orientation of 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

20˚-30˚

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 13 mm (1/2") 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.

Page 12

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

5˚-10˚

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

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

3. While depressing spindle lock, thread clamp nut (H) on spindle, piloting the raised hub on the clamp nut into the center of sanding 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

5˚-15˚

surface. The sanding 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. 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.

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.

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.

WARNING: A closed, 2-sided cutting wheel guard is not included with this tool but is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See page 8 for more information.

MOUNTING CLOSED (TYPE 1) GUARD

WARNING: 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.

1. Open the guard latch (M). Align the lugs (N) on

the guard with the slots (O) 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 (I) 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 guard by hand when the latch is in closed position. If rotation is possible, tighten the adjusting screw (P) 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 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 (P) 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

WARNING: 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 unthreaded backing flange and 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 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

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.

Cleaning

WARNING: Blow dirt and dust out of all air vents with dr y air at least once a week. Wear proper ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/ MSHA respiratory protection when performing this.

Blowing dust and grit out of motor and switch actuator using clean, dr y 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 fur ther 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. Wear proper ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/MSHA respiratory protection when performing this.
