The vibration emission level given in this information sheet has been measured in accordance with a
standardised test given in EN 60745 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.

WARNING: To reduce the risk of injury,
read the instruction manual.
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 batteryoperated (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.
e)
f)
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.
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.
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.
37
EN GLI S H
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) BATTERY TOOL USE AND CARE
a) Recharge only with the charger specified
by the manufacturer. A charger that is
suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.
b) Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
c) When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws or other
small metal objects that can make a
connection from one terminal to another.
38
d)
Shorting the battery terminals together may
cause burns or a fire.
Under abusive conditions, liquid may be
ejected from the battery, avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
6) 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 handles supplied with the tool.
Loss of control can cause personal injury.
• Hold power tools by insulated gripping
surfaces when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a “live” wire will make
exposed metal parts of the tool “live” and could
give the operator an electrical shock.
• 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.
Hammering operations cause chips to fly. Flying
particles can cause permanent eye damage.
Wear a dust mask or respirator for applications
that generate dust. Ear protection may be
required for most applications.
• Keep a firm grip on the tool at all times.
Do not attempt to operate this tool
without holding it with both hands. It is
recommended that the side handle be used at
all times. Operating this tool with one hand will
result in loss of control. Breaking through or
encountering hard materials such as re-bar may
be hazardous as well. Tighten the side handle
securely before use.
• Do not operate this tool for long periods of
time. Vibration caused by hammer action may
be harmful to your hands and arms. Use gloves
to provide extra cushion and limit exposure by
taking frequent rest periods.
ENGLISH
• Do not recondition bits yourself. Chisel
reconditioning should be done by an authorized
specialist. Improperly reconditioned chisels
could cause injury.
DATE CODE POSITION
• Wear gloves when operating tool or
changing bits. Accessible metal parts on the
tool and bits may get extremely hot during
operation. Small bits of broken material may
damage bare hands.
Example:
• Never lay the tool down until the bit has
come to a complete stop. Moving bits could
cause injury.
• Do not strike jammed bits with a hammer to
dislodge them. Fragments of metal or material
chips could dislodge and cause injury.
• Slightly worn chisels can be resharpened by
grinding.
• Keep the power cord away from the rotating
bit. Do not wrap the cord around any part of
your body. An electric cord wrapped around a
spinning bit may cause personal injury and loss
of control.
Residual Risks
The following risks are inherent to the use of rotary
hammers:
– Injuries caused by touching the rotating parts or
hot parts of the tool.
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 squeezing fingers when changing the
accessory.
– Health hazards caused by breathing dust
developed when working in concrete and/or
masonry.
Markings on Tool
The following pictograms are shown on the tool:

This charger will not charge a faulty battery pack.
The charger will indicate faulty battery by refusing to
light or by displaying problem pack or charger blink
pattern.
NOTE: This could also mean a problem with a
charger.
If the charger indicates a problem, take the charger
and battery pack to be tested at an authorised
service centre.
Hot/Cold Pack Delay
When the charger detects a battery that is too hot
or too cold, it automatically starts a hot/cold pack
delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.
XR Li-Ion tools are designed with an Electronic
Protection System that will protect the battery
against overloading, overheating or deep discharge.
ENGLISH
The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the
Li-Ion battery on the charger until it is fully charged.
A cold battery pack will charge at about half the rate
of a warm battery pack. The battery pack will charge
at that slower rate throughout the entire charging
cycle and will not return to maximum charge rate
even if the battery warms.
Important Safety Instructions for All
Battery Packs
When ordering replacement battery packs, be sure
to include the catalogue number and voltage.
The battery pack is not fully charged out of the
carton. Before using the battery pack and charger,

never depress the battery release button
without removing the battery pack.
Depressing the battery release button
without removing the battery pack can
result in the battery pack falling out
unexpectedly.
NOTE: For best results, make sure your battery
pack is fully charged.
TO INSTALL THE BATTERY PACK INTO THE TOOL HANDLE
1. Align the battery pack (f) with the rails inside the
tool’s handle (fig. 3).
2. Slide it into the handle until the battery pack is
firmly seated in the tool and ensure that it does
not disengage.
TO REMOVE THE BATTERY PACK FROM THE TOOL
1. Press the battery release button (g) and firmly
pull the battery pack out of the tool handle.
2. Insert battery pack into the charger as
described in the charger section of this manual.
FUEL GAUGE BATTERY PACKS (FIG. 3)
Some DEWALT battery packs include a fuel gauge
which consists of three green LED lights that
indicate the level of charge remaining in the battery
pack.
To actuate the fuel gauge, press and hold the fuel
gauge button (n). A combination of the three green
LED lights will illuminate designating the level of
charge left. When the level of charge in the battery
is below the usable limit, the fuel gauge will not
illuminate and the battery will need to be recharged.
NOTE: The fuel gauge is only an indication of the
charge left on the battery pack. It does not indicate
tool functionality and is subject to variation based
on product components, temperature and end-user
application.

Variable Speed Switch (fig. 1)
To turn the tool on, squeeze the trigger switch (a). To
turn the tool off, release the trigger switch. Your tool
is equipped with a brake. The tool holder will stop as
soon as the trigger switch is fully released.
The variable speed trigger switch enables you to
select the best speed for a particular application.
The farther you squeeze the trigger switch, the faster
the tool will operate. For maximum tool life, use
variable speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is
not recommended. It may damage the switch and
should be avoided.
Side Handle (fig. 1)
WARNING: To reduce the risk of
personal injury, ALWAYS operate
the tool with the side handle properly
installed. 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.
The side handle (e) clamps to the front of the gear
case and may be rotated 360˚ to permit right- or
left-hand use. Side handle must be tightened
sufficiently to resist the twisting action of the tool if
the accessory binds or stalls. Be sure to grip the
side handle at the far end to control the tool
during a stall.
To loosen side handle, rotate counterclockwise.
Forward/Reverse Control Button
(fig. 1, 2)
WARNING: Always wait until the motor
has come to a complete standstill
before changing the direction of rotation.
A forward/reverse control button (b) determines the
direction of the tool and also serves as a lock off
button.
To select forward rotation, release the trigger switch
and depress the forward/reverse control button on
the right side of the tool.
To select reverse, release the trigger switch and
depress the forward/reverse control button on the
left side of the tool.
The center position of the control button locks the
tool in the off position. When changing the position
of the control button, be sure the trigger is released.
44
NOTE: The first time the tool is run after changing
the direction of rotation, you may hear a click on
start up. This is normal and does not indicate a
problem.
Worklight (fig. 1)
DCH143, DCH253, DCH254
There is a worklight (d) located on the front of the
tool. The worklight will be activated when the trigger
switch is squeezed. The worklight is activated
when the trigger switch is depressed, and will
automatically turn off 20 seconds after the trigger
switch is released. If the trigger switch remains
depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate
work surface and is not intended to be used as a
flashlight.
Selecting the Operating Mode (fig. 1)
WARNING: Do not select the operating
mode when the tool is running.
Your tool is equipped with a separate mode
selector (c) to switch between rotary drilling, rotary
hammering and hammering only mode.
Rotary drilling: for screwdriving and for drilling
into steel, wood and plastics.
Rotary hammering: for concrete and
masonry drilling.
Hammering only: for light chipping.
For rotary drilling, rotate the mode selector (c)
until the arrow points to the drill bit symbol (i). For
rotary hammering mode, align the arrow with the
hammerdrilling symbol (j). For hammering only mode,
align arrow with the hammer symbol (k).
NOTE: The mode selector (c) must be in rotary
drilling, rotary hammering or hammering only mode
at all times. There are no operable positions in
between.
Active Vibration Control (fig. 1)
The active vibration control neutralises rebound
vibration from the hammer mechanism. Lowering
hand and arm vibration, it allows more comfortable
use for longer periods of time and extends the life of
the unit.
ENGLISH
For best vibration control, hold the tool with one
hand on the main handle (h) and the other hand on
the side handle (e). The hammer only needs enough
pressure to engage the internal active vibration
control. Applying too much pressure will not make
the tool drill faster and active vibration control will not
engage.
SDS Plus® Tool Holder (fig. 5)
To insert a drill or chisel bit, insert the shank of the
bit about 19 mm (3/4") into SDS Plus® tool holder (l).
Push and rotate bit until it locks in place. The bit will
be securely held.
To release bit, pull the sleeve (m) back and remove
the bit.
Replacing the SDS Plus® Tool Holder
with the Keyless Chuck (fig. 7)
DCH254
1. Turn the locking collar (p) into the unlocked
position and pull the SDS Plus® tool holder (l)
off.
2. Push the keyless chuck (q) onto the spindle and
turn the locking collar into the locking position.
3. To replace the keyless chuck with the
SDS Plus® tool holder, first remove the keyless
chuck the same way as the SDS Plus® tool
holder was removed. Then replace the
SDS Plus® tool holder the same way as the
keyless chuck was replaced.
WARNING: Never use standard chucks
in the rotary hammering mode.
Overload Clutch
In case of jamming of a drill bit, the drive to the
drill spindle is interrupted. Because of the resulting
forces, always hold the tool with both hands and
take a firm stance.
OPERATION
Instructions for Use
• Do not drill or drive too deep to
prevent damage to the dust cover (o).
• Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly mounted.
WARNING: To reduce the risk of
serious personal injury, turn tool
off and disconnect battery pack
before making any adjustments or
removing/installing attachments or
accessories.
Proper Hand Position (fig. 1, 6)
WARNING: To reduce the risk of
serious personal injury, ALWAYS
use proper hand position as shown
in figure 6.
WARNING: To reduce the risk of
serious personal injury, ALWAYS hold
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the
main handle (h), with the other hand on the side
handle (e).
Drill Operation (fig. 1)
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
