General Power Tool 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.
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 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.
ENGLISH
6
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.
f) 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.
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 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
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger
on the switch or energising 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 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 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
Rotary Hammers
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• 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.

INTENDED USE
D25721, D25723
Your rotary hammer has been designed for
professional rotary drilling and chipping applications.
ENGLISH
8
D25871
Your chipping hammer has been designed for
professional chipping, chiselling and demolition
applications.
DO NOT use under wet conditions or in presence of
flammable liquids or gases.
These hammers are professional power tools.
DO NOT let children come into contact with the
tool. Supervision is required when inexperienced
operators use this tool.
• This product is not intended for use by persons
(including children) suffering from diminished
physical, sensory or mental abilities; 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.
Soft Start Feature
D25723
The soft start feature allows the tool to accelerate
slowly, thus preventing the drill bit from walking off
the intended hole position when starting.
The soft start feature also reduces the immediate
torque reaction transmitted to the gearing and the
operator if the hammer is started with the drill bit in
an existing hole.
Electronic Speed and Impact Control
(fig. 1, 3)
The electronic speed and impact control (g) offers
the following advantages:
– use of smaller accessories without risk of
breakage;
– minimised break-out when chiselling or drilling in
soft or brittle materials;
– optimal tool control for precise chiselling.
Torque Limiting Clutch
WARNING: The user must always
maintain a firm grip on the tool when in
operation.
The torque limiting clutch 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.
NOTICE: Always turn the tool off before
changing torque control settings or
damage to tool may result.
ULTIMATE TORQUE CONTROL (UTC)
D25723
In addition to the two-stage mechanical clutch,
Ultimate Torque Control (UTC) offers increased
user comfort and safety through an on-board,
anti-rotation technology capable of detecting if
the user loses control of the hammer. When a jam
is detected, the torque and speed are reduced
instantly. This feature prevents self rotation of the tool
reducing the occurrence of wrist injuries.
Service Indicator LEDs (fig. 3)
The yellow brushwear indicator LED (s) lights up
when the carbon brushes are nearly worn out to
indicate that the tool needs servicing within the next
8 hours of use.
D25721, D25723
The red service indicator LED (r) lights up if the
lock-on button (b) is used in any mode except the
chipping mode. On models fitted with Ultimate
Torque Control (UTC), the red LED indicator (r) lights
up if the anti-rotational device is activated. The red
indicator starts to flash if there is a fault with the tool
or the brushes have completely worn out (refer to
Brushes under Maintenance).
D25871
The red service indicator LED (r) lights up if there is
a fault with the tool or the brushes have completely
worn out (refer to Brushes under Maintenance).
Fully Vibration-dampened Main
Handle (fig. 1)
The dampers in the main handle (d) absorb the
vibrations transmitted to the user. This improves user
comfort during the operation.
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 EN 60745; therefore no
earth wire is required.
WARNING: 120 V units have to
be operated via a fail-safe isolating
transformer with an earth screen
between the primary and secondary
winding.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
DEWALT service organisation.
