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.
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.
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 a 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 and clothing away from
moving parts. Loose clothes, jewellery or long hair can be
caught in movingparts.

ENGLISH
Hammer Safety Warnings
• 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 the power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
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.
h ) 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
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 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.
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 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.
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.
h ) 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
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.
Cutting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the operator
an electricshock.
Safety Instructions When Using Long
DrillBits with Rotary Hammers
• 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.
Additional Safety Instructions for
RotaryHammer Drills
• 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.
• Do not recondition bits yourself. It should be done by an
authorized specialist. Improperly reconditioned bits could
causeinjury.
• 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.
• 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.
• 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.
• When working above the floor, make sure that the area
below is clear. Falling parts can cause injuries to bystanders.

ENGLISH
Side Handle (Fig.A, B)
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13 clamps to the front of the gear case and
may be rotated 360˚ to permit right- or left-hand use.
Mounting the Straight Side Handle (Fig.B)
1. Widen the ring opening of the side handle 13 by rotating
itcounterclockwise.
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.
Active Vibration Control (AVC) System
For best vibration control, hold the tool as described in Proper
Hand Position and apply just enough pressure so the damping
device on the main handle is approximately midstroke.
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.
The hammer only needs enough pressure to engage the active
vibraton control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
notengage.
DeWALT Tool Tag Ready (Fig. A)
Optional Accessory
Your hammer comes with mounting holes 11 and fasteners
for installing a DeWALT Tool Tag. You will need a T15 bit tip to
install the tag. The DeWALT Tool Tag is designed for tracking and
locating professional power tools, equipment, and machines
using the DeWALT Tool Connect™ app. For proper installation of
the DeWALT Tool Tag refer to the DeWALT Tool Tagmanual.
Lock-On Switch (Fig. A)
Chipping mode only
The lock-on switch 7 offers increased comfort in extended use
applications. To lock the tool on, depress the lock-on switch
while the tool is running. The tool will continue to run after the
switch is released. To unlock and turn off the tool, depress and
release theswitch.
Electronic Speed and Impact Control (Fig.A)
The electronic speed and impact control allows the use of
smaller drill bits without the risk of bit breakage, hammerdrilling
into light and brittle materials without shattering and optimal
tool control for precisechiselling.
To set the electronic speed and impact control dial 8, turn the
dial to the desired level. The higher the number, the greater
the speed and impact energy. Dial settings make the tool
extremely flexible and adaptable for many different applications.
The required setting depends on the bit size and hardness of
material beingdrilled.
• 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.
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. After the overload,
release and depress the trigger to re-engagedrive.
Mechanical Clutch
These tools are fitted with a mechanical clutch. The indication
that the clutch has activated will be an audible ratcheting
together with increasedvibration.
Anti-Rotation System
In addition to the clutch, an anti-rotation system offers increased
user comfort 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 stopped
instantly. This feature prevents self rotation of the tool.
The anti-rotation system indicator 9 will illuminate to
indicatestatus.

3. Set the mode selector switch3 to the rotary
hammerdrillingposition.
4. Turn the electronic speed and impact control dial8 to a
medium or high speedsetting.
5. Fit and adjust the side handle13.
6. Place the centerdrill on the spot and switch on the tool. Drill
until the core penetrates into the concrete approximately
1cm.
7. Stop the tool and remove the centerdrill. Place the core bit
back into the hole and continuedrilling.
8. When drilling through a structure thicker than the depth of
the core bit, break away the round cylinder of concrete or
core inside the bit at regularintervals.
To avoid unwanted breaking away of concrete around
the hole, first drill a hole the diameter of the centerdrill
completely through the structure. Then drill the cored hole
halfway from eachside.
9. Always turn the tool off when work is finished and
beforeunplugging.
Chipping and Chiselling (Fig.A, B)

lock it into one of 24positions. Refer to Indexing the
ChiselPosition.
2. Set the mode selector switch3 to the 'hammering
only'position.
3. Set the electronic speed and impact control dial8.
4. Fit and adjust the side handle13.
5. Turn the tool on and startworking.
6. Always turn the tool off when work is finished and
beforeunplugging.
Recommendations for Tool Operation
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect thebit. A smooth even flow of material indicates the
proper drillingrate.
• If drilling thin material or material that is prone to splinter,
use a wood“back-up”block to prevent damage to
theworkpiece.
WARNING:
• Do not use this tool to mix or pump easily combustible
or explosive fluids (benzine, alcohol,etc.).
• Do not mix or stir inflammable liquids
labelledaccordingly.
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.
