GENERAL POWER TOOL SAFETY WARNINGS

WARNING: 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.

SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains‑operated (corded) power tool or battery‑operated (cordless) power tool.

Work Area Safety
Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical Safety
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.
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.
Do not 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 for carrying, pulling or unplugging the power tool. cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
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.
If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces 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 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.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non‑skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jeweler. Keep your hair and clothing away from moving parts. Loose clothes, jeweler or long hair can be caught in moving parts.
jeweler. Keep your hair and clothing away from moving parts. Loose clothes, jeweler or long hair can be caught in moving parts. extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust‑related hazards.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Power Tool Use and Care
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.
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.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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.
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.
Maintain power tools and accessories. 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.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, 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.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Service
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.

Drill Safety Warnings

Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, 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 could give the operator an electric shock.
Wear ear protectors. Exposure to noise can cause hearing loss.
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.
Wear safety goggles or other eye protection. Drilling operations cause chips to fly. Flying particles can cause permanent eye damage.
Bits and tools get hot during operation. Wear gloves when touching them.
Keep handles dry, clean, free from oil and grease. It is recommended to use rubber gloves. This will enable better control of the tool.

Safety Instructions When Using Long Drill Bits

Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

Residual Risks
WARNING: We recommend the use of a residual current device with a residual current rating of 30mA or less.
In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided.
These are:

Impairment of hearing.
Risk of personal injury due to flying particles.
Risk of burns due to accessories becoming hot during operation.
Risk of personal injury due to prolonged use.

ASSEMBLY AND ADJUSTMENTS

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. An accidental start‑up can cause injury.

Side Handle (Fig. C) DEWALT-D21570-1300W-2 speed-Dry-Diamond-
Drill-03

WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed and tightened. Failure to do so may result
in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control.

A side handle 3 is supplied with your drill. The side handle clamps to the front of the gear case and can be rotated 360 degrees to permit right- or left-hand use.
After the side handle is rotated into position, it should be pushed rearward until the slots 3 on the lip of the side handle are aligned and fully engaged with the projecting tabs 12 on the underside of the gear case. The side handle is then securely clamped by turning clockwise until tight.

Torque Limiting Clutch
This tool is equipped with a torque limiting clutch that reduces the maximum torque reaction transmitted to the operator in case of jamming of a drill bit. This feature also prevents the gearing and electric motor from stalling. The torque limiting clutch has been factory-set and cannot be adjusted.

E-CLUTCH Anti-Lock Control™ (Fig. B)
D21570, DWD530
Your DEWALT drill may come with an electronic feature called E-CLUTCH Anti- Lock Control™. It is designed to help you control the drill during a stall and keep it from pulling out of your hands. This may be encountered when drilling in steel or using large bits in wood.
As a stall situation presents itself, the motor cycles on and off for a set period of time. This reduces the reaction of the stall and allows you to keep the drill under control. Releasing the trigger resets the E-Clutch and the unit will operate in normal mode when the trigger is depressed again.
The E-CLUTCH Anti-Lock Control™ also incorporates an overload protection feature designed to help prevent the unit from becoming too hot during high load applications.
If the unit becomes excessively hot during operation this feature will cut the motor, The feature will continue to cut the motor if it is restarted and placed under a high load before it has cooled off.
Figure B shows the instruction label 13 mounted on the housing. There are two alert modes.

Engaged Mode: When a stall situation presents itself, the indicator light will come on and stay on as the motor cycles on and off for a set period of time before the E-CLUTCH Anti-Lock Control™ completely shuts the tool down. When the unit is running in normal mode, there will be no light.
Problem Mode: A series of continual flashes of the indicator light as the trigger is pulled, indicates that the electronics are no longer functioning. The tool may still be able to function without the benefit of E-CLUTCH Anti-Lock Control™ but should be serviced as soon as possible.
