The vibration emission level given in this information sheet has been
measured in accordance with a standardised test given in EN60745 and
may be used to compare one tool withanother. It may be used for a
preliminary assessment ofexposure.
WARNING: The declared vibration emission level represents the
main applications of thetool. However if the tool is used for different
applications, with different accessories or poorly maintained, the
vibration emission maydiffer. This may significantly increase the
exposure level over the total workingperiod.
An estimation of the level of exposure to vibration should also take
into account the times when the tool is switched off or when it is
running but not actually doing thejob. This may significantly reduce
the exposure level over the total workingperiod.
Identify additional safety measures to protect the operator from the
effects of vibration such as: maintain the tool and the accessories, keep
the hands warm, organisation of workpatterns.

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. 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.

ENGLISH
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3, 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.
WARNING: We recommend the use of a residual current device with a
residual current rating of 30mA orless.
Residual Risks
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.
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.
WARNING: 115 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.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the oldplug.
• Connect the brown lead to the live terminal in theplug.
• Connect the blue lead to the neutralterminal.
WARNING: No connection is to be made to the earthterminal.
Follow the fitting instructions supplied with good qualityplugs.
Recommended fuse: 13A.
Using an Extension Cable
An extension cord should not be used unless absolutelynecessary. Use an
approved extension cable suitable for the power input of your charger (see
Technical Data). The minimum conductor size is1.5 mm2; the maximum
length is30m.
When using a cable reel, always unwind the cablecompletely.

ENGLISH
The D25820, D25831 chipping hammers have been designed for
professional chipping, chiselling and demolitionapplications.
DO NOT use under wet conditions or in the 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.
• 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; 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
D25601, D25602, D25603, D25831
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. A, C)
D25601, D25602, D25603, D25831
The electronic speed and impact control7 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.
Complete Torque Control (CTC) (Fig.C) D25602
Complete Torque Control (CTC) offers the user a two-stage mechanical
clutch with adjustable torqueoptions. Adjusting the torque provides
increased control for variousapplications.
The low setting (40Nm) allows the tool to operate at a reduced torque
level increasing control for many solid drillingapplications. The high setting
(80Nm) is available for more demanding applications such as core drilling
and the use of large diameter solidbits.
Refer to Setting the Two Stage Mechanical Clutch for moreinformation.
Ultimate Torque Control (UTC) (Fig.C) D25603
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. A, C)
D25601, D25602, D25603, D25831
The yellow brushwear indicator LED17 lights up when the carbon brushes
are nearly worn out to indicate that the tool needs servicing within the next
8 hours ofuse.
D25601, D25602, D25603
The red service indicator LED18 lights up if the lock-on button2 is
used in any mode except the chippingmode. On models fitted with
Ultimate Torque Control (UTC), the red LED indicator18 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).
D25831
The red service indicator LED18 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. A)
D25601, D25602, D25603, D25831
The dampers in the main handle4 absorb the vibrations transmitted to
theuser. This improves user comfort during theoperation.

Turn the dial7 to the desiredlevel. Turn the dial upwards for higher
speed and downwards for lowerspeed. The required setting is a matter of
experience, e.g.
• when chiselling or drilling in soft, brittle materials or when minimum
break-out is required, set the dial to a low setting;
• when breaking or drilling in harder materials, set the dial to a
highsetting.
Setting the Two Stage Mechanical Clutch (Fig. C)
D25602, D25603
NOTICE: Always turn the tool off before changing torque control
settings or damage to the tool mayresult.
Move the torque control lever21 to setting 40Nm or 80Nm as needed
forapplication.
• Clutch Setting 40Nm19 is designed for most drilling applications and
is designed to easily clutch out when the drill bit encounters re-bar or
other foreignsubstances.
• Clutch Setting 80Nm20 is designed for higher torque applications
such as core-bits and deep hole drilling and is designed to clutch out at
a higher torquethreshold.
NOTE: If it is not possible to select position 80Nm, run the unit under load
and tryagain.
Each time the tool is plugged in, it will automatically default to clutch
