SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listedbelowmayresultinelectricshock,reand/or
seriousinjury.
Save all warnings and instruc-
tions for future reference.
Theterm"powertool"inthewarningsreferstoyour
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
1. 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. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators.Thereisanincreasedriskofelec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4.
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.

4ENGLISH
5. 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.
6. 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.
7. Power tools can produce electromagnetic
elds (EMF) that are not harmful to the user.
However, users of pacemakers and other similar
medical devices should contact the maker of their
device and/or doctor for advice before operating
this power tool.
Personal Safety
1. 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 inuence of drugs, alcohol or med-
ication.Amomentofinattentionwhileoperating
powertoolsmayresultinseriouspersonalinjury.
2. 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.
3. 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ngerontheswitchorenergisingpowertools
that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times.Thisenablesbettercontrol
of the power tool in unexpected situations.
6. 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.
7. 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.
8. 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.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
Power tool use and care
1. 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.
2.
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.
3. Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5.
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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7.
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.
8. Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasp-
ing surfaces do not allow for safe handling and control
of the tool in unexpected situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled.Theentangle-
ment of cloth work gloves in the moving parts may
resultinpersonalinjury.

OPERATION
CAUTION: Always use the side grip (auxiliary
handle) and rmly hold the tool by both side grip
and switch handle during operations.
CAUTION: Always make sure that the work-
piece is secured before operation.
CAUTION: Do not pull the tool out forcibly
even the bit gets stuck. Loss of control may
cause injury.
CAUTION: The dust collection system is
intended for drilling in concrete only. Do not use
the dust collection system for drilling in metal or
wood.
CAUTION: When using the tool with the dust
collection system, be sure to attach the lter
to the dust collection system to prevent dust
inhalation.
CAUTION: Before using the dust collection
system, check that the lter is not damaged.
Failure to do so may cause dust inhalation.
CAUTION: The dust collection system col-
lects the generated dust at a considerable rate,
but not all dust can be collected.
NOTICE: Do not use the dust collection system
for core drilling or chiseling.
NOTICE: Do not use the dust collection system
for drilling in wet concrete or use this system
in wet environment. Failure to do so may cause
malfunction.
NOTE: If the battery cartridge is in low temperature,
the tool’s capability may not be fully obtained. In this
case, warm up the battery cartridge by using the
tool with no load for a while to fully obtain the tool’s
capability.
Hammer drilling operation
CAUTION:Thereistremendousandsudden
twisting force exerted on the tool/drill bit at the time of
hole break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the side
grip (auxiliary handle) and rmly hold the tool by
both side grip and switch handle during opera-
tions. Failure to do so may result in the loss of control
ofthetoolandpotentiallysevereinjury.
Set the action mode changing knob to the symbol.
Position the drill bit at the desired location for the hole,
then pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position
and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the drill bit partially from the hole.
By repeating this several times, the hole will be cleaned
out and normal drilling may be resumed.
NOTE: Eccentricity in the drill bit rotation may occur
whileoperatingthetoolwithnoload.Thetoolauto-
maticallycentersitselfduringoperation.Thisdoesnot
affect the drilling precision.
Chipping/Scaling/Demolition
