General Safety Instructions

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

• 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 adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrical-

ly 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.

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

English

away from moving parts. Loose clothes, 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 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 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

• 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 always be above tool 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.

English

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

inappropriate accessories can result in injury.

• 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. Flaws may

cause wheel breakage.

• 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 using a sander or grinder. 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.

• 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.

CAUTION: Type 1 Abrasive and Diamond Cut-Off Wheels may

not be used on this tool. A Type 1 Cut-Off Wheel Guard is not available for the DW400.

CAUTION: Use extra care when grinding into a corner as a

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

CAUTION: Wear appropriate personal hearing protection

during use. Under some conditions and duration of use, noise

from this product may contribute to hearing loss.

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.

English

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.

EDGE GRINDING WITH GRINDING WHEELS

WARNING: Edge grinding and cutting can be performed only with

Type 27 wheels that are designed and specified for this purpose.

WARNING: 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 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" in depth). The open side of the guard must be positioned away from the operator.

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. 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.

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 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.

MOUNTING SANDING BACKING PADS

CAUTION: The proper guard must be re-

installed for the grinding wheel, sanding flap disc, wire brush or wire wheel applications after sanding applications are complete.

1. Push the hub of the disc nut (M) through the center of the sanding disc (L), as far as it will go, and also through the backing disc (K).

2. Assemble the disc nut hub (J), backing pad, sanding disc, and disc nut as shown.

3. Be sure the disc nut extends through the discs into the disc nut hub.

5˚-10˚

English

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.

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 clean up is completed.

2. 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 N.I.O.S.H. approved mask.

3. 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.

4. Thread the assembled parts (clockwise) completely down on the spindle.

5. Depress the spindle lock button while turning the sanding disc until the sanding disc and clamp nut are snug.

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

USING SANDING BACKING PADS

Choose the proper grit sanding disc 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 lower 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 sanding disc should contact approximately one inch of work surface. The lower angle will produce a smoother surface. Using only the outer edge at a higher angle will produce an irregular and bumpy finish. However, if the disc is used flat on the surface, the tool will be difficult to control.

5˚-15˚

English

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.

CLEANING AND DISPOSAL

1. 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.

2. 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.

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

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. Wire

brushes can become sharp.

MOUNTING WIRE BRUSHES AND WIRE WHEELS

CAUTION: Turn off and unplug the tool before making any

adjustments or removing or installing attachments or acces-

sories. Before reconnecting the tool, actuate and release switch to ensure that the tool is off.

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 BRUSHES AND WIRE WHEELS

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 brushng paint as when sanding paint (see page 10).

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 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.
