General Power Tool Safety Warnings
WARNING! Read all safety warnings and instructions Failure to follow the warnings and instructions 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.
1) WORK AREA SAFETY
a) Keep the 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 that
may ignite 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 the
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 the 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. The use of a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply.
The use of an RCD 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 personal protective equipment.
Always wear eye protection. Protective equipment such as dust masks, non-skid
safety shoes, hard hats, or hearing protection used for appropriate conditions
will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position
before connecting to a 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.
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 jewelry. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, 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. The 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 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.
Additional Safety Instructions for Drills
-
Wear ear protectors. Exposure to noise can cause hearing loss.
-
Hold power tools by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessories contacting a “live” wire may make exposed metal parts of the tool “live” and could give the operator an electric shock.
-
Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
-
Wear safety goggles or other eye protection. Drilling operations cause chips to fly. Flying particles can cause permanent eye damage.
-
Bits, tools, and drilling area get hot during operation. Wear gloves when touching them.

INTENDED USE
Your D21580, D21582 diamond drilling machine has been designed for dry
drilling into masonry materials such as brick, breezeblock, etc. with a dry
diamond core bit, up to 92 mm, in conjunction with dust extraction.
Your D21582 diamond drilling machine can also be used for wet drilling into
engineered bricks, stone concrete, and reinforced concrete with wet diamond
core bits and a water supply.
The machine can be used handheld in applications up to 100 mm for masonry or
40 mm for concrete. When drilling holes larger than 100 mm diameter in masonry
or 40 mm diameter in concrete, the machine must be used on a drill stand, e.
g. D215821.
DO NOT use under wet conditions or in presence of flammable liquids or
gases.
These diamond drills are professional power tools.
DO NOT let children come into contact with the tool. Supervision is required
when inexperienced operators use this tool.
- Young children and the infirm. This appliance is not intended for use by young children or infirm persons without supervision.
- This product is not intended for use by persons (including children) suffering from diminished physical, sensory or mental abilities; or lack of experience, knowledge, or skills unless they are supervised by a person responsible for their safety. Children should never be left alone with this product.
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.
Electronic Overload Protection
The electronic overload protection offers additional safety: if the current
approach a certain limit, the warning indicator LED (C) lights up to indicate
that the machine switches into overload mode if the operation is continued at
the same pressure level.
Reduced operator pressure on the machine makes the electronics switch back
into normal mode.
If continuous overload pressure is applied, the machine switches off. Thus,
overheating of the motor windings is avoided. The machine is operational again
after the load has been released.
Thermal Protection
After the machine has worked in overload for a long period of time, the thermal protection shuts off the machine to protect the motor. The machine will be operational after the thermal protection has cooled down. The time of cooling down depends on the overheating of the motor and the ambient temperature.
Water Supply
D21582
The integrated water swivel works directly through the motor shaft to provide
continuous cooling of the core bit in wet drilling applications.
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.
Your DEWALT tool is double insulated in accordance with EN60745; therefore no
earth wire is required.
In case of cord or plug replacement, the tool must only be repaired by an
authorized service agent or by a qualified electrician.

Troubleshooting
If your tool seems not to operate properly, follow the instructions below. If
this does not solve the problem, please contact your repair agent.
The core bit does not cut
Material too hard for core bit
-
Choose a more appropriate core bit (with softer segments).
-
Apply wet drilling when appropriate.
Segments look glazed and polished
• Drill in abrasive material to re-expose diamond segments.
Evacuated water is too clear and too fluid
Water flow slows down the cutting action and prevents the diamond segments from self-sharpen. -
Reduce water flow.
Dust accumulating in the core bit
Accumulating dust slows down the drilling speed. -
Use the appropriate dust extraction device.
-
Disengage the drill bit regularly to evacuate cuttings.
Rotating speed not appropriate -
Refer to the technical data for proper speed ratings.
Segments and cores are burnt -
Increase water flow.
Segments wear too fast -
Choose a more appropriate core bit (with harder segments).
-
Reduce the pressure applied on the core bit.
