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.

SAFETY INSTRUCTIONS FOR POWER TOOLS

When using power tools, always observe the safety regulations applicable in your
country to reduce the risk of fire, electric shock and personal injury. Read the following
safety instructions before attempting to operate this product. Keep these instructions in
a safe place.

WARNING: To reduce the risk of injury, user must 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 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.

3

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.

Electrical Safety

The electric motor has been designed for one voltage range only. Always check that
the power supply corresponds to the voltage on the rating plate. 220–240 V AC
means your tool will operate on alternating current. Operation at a voltage outside this
range can cause loss of power and can result in overheating. All DEWALT tools are
factory tested; if this tool does not operate, check the power supply. Your DEWALT

tool is double insulated, therefore no earth wire is required.

• Young children and the infirm. This appliance is not intended for use by young
children or infirm persons without supervision.

– This appliance is not intended for use by persons (including children) with

reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.

– Children should be supervised to ensure that they do not play with the appliance.

• Replacement of the supply cord. If the supply cord or plug is damaged, it must
be replaced by the manufacturer or an authorised DEWALT Service Centre in
order to avoid a hazard.

Extension Cords

CAUTION: Use only extension cords that are approved by the country’s Electrical
Authority. Before using extension cords, inspect them for loose or exposed wires,
damaged insulation and defective fittings. Replace the cord if necessary.

Rotary Hammers 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 power tools 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 will make exposed metal parts of the power
tool “live” and could give the opeartor 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

WARNING: ALWAYS wear approved protective safety equipment complying with
the following standards:

• Eye protection: AS/NZS1337 Eye Protectors for Industrial Applications;

• Hearing protection: AS/NZS1270 Acoustics – Hearing Protection;

• Respiratory protection: AS/NZS1716 Respiratory Protective Devices.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to cause cancer, birth defects
or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding,

drilling, and other construction activities. Wear protective clothing and wash
exposed areas with soap and water. Allowing dust to get into your mouth, eyes,

or lay on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disburse dust, which may cause
serious and permanent respiratory or other injury. Always use AS/NZS1716 approved
respiratory protection appropriate for the dust exposure. Direct particles away from
face and body.

WARNING: Always wear proper personal hearing protection that conforms to
AS/NZS1270 during use. Under some conditions and duration of use, noise from this

product may contribute to hearing loss.

control. Breaking through or encountering hard materials such as re-bar may be
hazardous as well. Tighten the side handle securely before use.

• The hammer is only for light chiselling applications.

• The forward/reverse switch must be in the forward position when chiselling.

• Do not use this tool to mix or pump easily com busti ble or explosive fluids (ben­zine, alcohol, etc.).

• Do not mix or stir inflammable liquids labelled accordingly.

• 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. Slightly worn chisels can be resharpened by
grinding. 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.

• 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.

• Air vents often cover moving parts and should be avoided. Loose clothes,

DRILLING IN METAL

An SDS Plus

®

to round shank adaptor chuck is required. Ensure that tool is in drill­only mode. Start drilling with slow speed and increase to full power while applying
firm pressure on the tool. A smooth even flow of metal chips indicates the proper
drilling rate. Use a cutting lubricant when drilling metals. The exceptions are cast iron
and brass which should be drilled dry.
NOTE: Large [5/16" to 1/2" (7.9 mm to 12.7 mm)] holes in steel can be made easier
if a pilot hole [5/32" to 3/16" (4 mm to 4.8 mm)] is drilled first.

DRILLING IN WOOD

An SDS Plus

®

to round shank adaptor chuck is required. Ensure that tool is in drill-only
mode. Start drilling with slow speed and increase to full power while applying firm
pressure on the tool. Holes in wood can be made with the same twist drills used for
metal. These bits may overheat unless pulled out frequently to clear chips from the flutes.
For larger holes, use spade bits, power auger bits, or hole saws. Work that is apt to
splinter should be backed up with a block of wood.

HAMMERDRILL OPERATION

1. When drilling, use just enough force on the hammer to keep it from bouncing

excessively or “rising” off the bit. Too much force will cause slower drilling
speeds, overheating, and a lower drilling rate.

2. Drill straight, keeping the bit at a right angle to the work. Do not exert side

pressure on the bit when drilling as this will cause clogging of the bit flutes and a
slower drilling speed.

3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit

partially out of the hole with the tool still running to help clear debris from the
hole.

4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of

dust indicates the proper drilling rate.

WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is
anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to
prevent damage to the material.
Press mode selector button (F) and turn the mode selector (G) to the drill bit symbol
for drilling, to the hammer symbol for hammering or to the hammerdrill symbol for
hammerdrilling.

DRILLING OPERATION

1. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL,

use high-speed steel twist drill bits or hole saws. Use a cutting lubricant when
drilling metals. The exceptions are cast iron and brass which should be drilled
dry. For MASONRY, use carbide-tipped bits or masonry bits. A smooth, even flow
of dust indicates the proper drilling rate.

2. Always apply pressure in a straight line with the bit. Use enough pressure to keep

the drill bit biting, but do not push hard enough to stall the motor or deflect the
bit.

3. Hold tool firmly with both hands to control the twisting action of the drill.

4. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE

TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of
stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A

STALLED DRILL – THIS CAN DAMAGE THE DRILL.

5. To minimize stalling or breaking through the material, reduce pressure on drill and

ease the bit through the last fractional part of the hole.

WARNING: Drill may stall if overloaded causing a sudden twist. Always expect
the stall. Grip the drill firmly with both hands to control the twisting action and avoid
injury.

6. Keep the motor running when pulling the bit back out of a drilled hole. This will

help prevent jamming.

7. With variable speed drills there is no need to center punch the point to be drilled.

Use a slow speed to start the hole and accelerate by squeezing the trigger harder
when the hole is deep enough to drill without the bit skipping out.

9

DEPTH ROD (FIG. 5)

TO ADJUST THE DEPTH ROD

1. Push in and hold the depth rod release button (J) on the side handle.

2. Move the depth rod (D) so the distance between the end of the rod and the end

of the bit equals the desired drilling depth.

3. Release the button to lock rod into position. When drilling with the depth rod, stop

when end of rod reaches surface of material.
