GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
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.

4
ENGLISH
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.
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.
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 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.
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
ChippingHammers
• Wear ear protectors. Exposure to noise can cause
hearingloss.
• Use auxiliary handle 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.
• 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. Chisel reconditioning
should be done by an authorized specialist. Improperly
reconditioned chisels 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.

Always check that the power supply corresponds to the voltage
on the rating plate.
Your DeWALT tool is double insulated in accordance
with IEC60745; therefore no earth wire is required.
If the supply cord is damaged, it must be replaced only by
DeWALT or an authorised serviceorganisation.
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
If an extension cable is required, use an approved 3–core
extension cable suitable for the power input of this tool (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.
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.
SAVE THESE INSTRUCTIONS
• 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 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.

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2 clamps to the front of the gear case and may
be rotated 360˚ to permit right- or left-hand use.
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 chip faster and active vibration control will notengage.
DeWALT Tool Tag Ready (Fig. A)
Optional Accessory
Your hammer comes with DeWALT tool tag mounting holes 9
and fasteners for installing a DeWALT Tool Tag. You will need a
T20 bit tip to install the tag. The DeWALT Tool Tag is designed
