General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tions 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
4. 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.
5. 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.
6. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
7. 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.
8. 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.
9. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit inter-
rupter (GFCI) protected supply. Use of an GFCI
reduces the risk of electric shock.
Personal safety
10. 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.

7ENGLISH
11. 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.
12. Prevent unintentional starting. Ensure the
switch is in the o󰀨-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.
13. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
16. 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.
Power tool use and care
17. 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.
18. Do not use the power tool if the switch does
not turn it on and o󰀨. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
19. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
20. 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.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may a󰀨ect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
for operations di󰀨erent from those intended could
result in a hazardous situation.
Battery tool use and care
24. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
25. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
26. 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. Shorting the battery termi-
nals together may cause burns or a re.
27. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
Service
28. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
29. Follow instruction for lubricating and chang-
ing accessories.
30. Keep handles dry, clean and free from oil and
grease.
CORDLESS ROTARY HAMMER
SAFETY WARNINGS
1. Wear ear protectors. Exposure to noise can
cause hearing loss.
2. Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
3. Hold power tool by insulated gripping sur-
faces, when performing an operation where
the cutting accessory may contact hidden wir-
ing. Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool “live”
and could give the operator an electric shock.
4. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place before
operation.
6. Under normal operation, the tool is designed
to produce vibration. The screws can come
loose easily, causing a breakdown or accident.
Check tightness of screws carefully before
operation.
7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for
a while by operating it under no load. This
will loosen up the lubrication. Without proper
warm-up, hammering operation is di󰀩cult.
8. Always be sure you have a rm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool rmly with both hands.

8ENGLISH
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area
when operating. The bit could y out and
injure someone seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
SAVE THESE INSTRUCTIONS.
WARNING: DO NOT let comfort or famil-
iarity with product (gained from repeated
use) replace strict adherence to safety
rules for the subject product. MISUSE or
failure to follow the safety rules stated in
this instruction manual may cause serious
personal injury.

OPERATION
Hammer drilling operation
► Fig.20
Set the action mode changing knob to the symbol.
Position the 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 bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
• There is a tremendous and sudden twisting
force exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles, or when striking rein-
forcing 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 operations. Failure to do so may result
in the loss of control of the tool and potentially
severe injury.
NOTE: Eccentricity in the bit rotation may occur while
operating the tool with no load. The tool automatically
centers itself during operation. This does not a󰀨ect
the drilling precision.
Blow-out bulb (optional accessory)
► Fig.21: 1. Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Chipping/Scaling/Demolition
► Fig.22
Set the action mode changing knob to the symbol.
Hold the tool rmly with both hands. Turn the tool on
and apply slight pressure on the tool so that the tool will
not bounce around, uncontrolled. Pressing very hard on
the tool will not increase the e󰀩ciency.
Drilling in wood or metal
► Fig.23: 1. Chuck adapter 2. Keyless drill chuck
► Fig.24: 1. Sleeve 2. Ring
Use the optional drill chuck assembly. When installing it,
refer to “Installing or removing the bit” described on the
previous page.
Set the action mode changing knob so that the pointer
points to the symbol.
For model DHR243
CAUTION:
• Never use “rotation with hammering” when the
drill chuck assembly is installed on the tool. The
drill chuck assembly may be damaged. Also, the
drill chuck will come o󰀨 when reversing the tool.

wise to tighten the chuck. To remove the bit, hold the
ring and turn the sleeve counterclockwise.
Set the action mode changing knob to the symbol.
You can drill up to 13 mm diameter in metal and up to
32 mm diameter in wood.
CAUTION:
• Never use “rotation with hammering” when the
quick change drill chuck is installed on the tool.
The quick change drill chuck may be damaged.
Also, the drill chuck will come o󰀨 when reversing
the tool.
• Pressing excessively on the tool will not speed
up the drilling. In fact, this excessive pressure
will only serve to damage the tip of your bit,
decrease the tool performance and shorten the
service life of the tool.
• There is a tremendous twisting force exerted
on the tool/bit at the time of hole breakthrough.
Hold the tool rmly and exert care when the bit
begins to break through the workpiece.
• A stuck bit can be removed simply by setting
the reversing switch to reverse rotation in order
to back out. However, the tool may back out
abruptly if you do not hold it rmly.
• Always secure small workpieces in a vise or
similar hold-down device.

Peringatan Keselamatan Umum
Mesin Listrik
PERINGATAN Bacalah semua peringatan
keselamatan dan semua petunjuk. Kelalaian
mematuhi peringatan dan petunjuk dapat menyebabkan
sengatan listrik, kebakaran dan/atau cedera serius.
Simpanlah semua peringatan
dan petunjuk untuk acuan di
masa depan.
Istilah “mesin listrik” dalam semua peringatan mengacu
pada mesin listrik yang dijalankan dengan sumber listrik
jala-jala (berkabel) atau baterai (tanpa kabel).
Keselamatan tempat kerja
1. Jaga tempat kerja selalu bersih dan
berpenerangan cukup. Tempat kerja yang
berantakan dan gelap mengundang kecelakaan.
2. Jangan gunakan mesin listrik dalam
lingkungan yang mudah meledak, misalnya
terdapat cairan, gas, atau debu yang mudah
terbakar. Mesin listrik menimbulkan bunga api
yang dapat membakar debu atau uap tersebut.
3. Jauhkan anak-anak dan orang lain saat
menggunakan mesin listrik. Jika perhatian
terpecah, Anda mungkin saja kehilangan kendali.
Keamanan kelistrikan
4. Steker mesin listrik harus cocok dengan
stopkontak. Jangan sekali-kali mengubah
steker dengan cara apa pun. Jangan
menggunakan steker adaptor dengan mesin
listrik yang terbumi (dibumikan). Steker yang
tidak diubah dan stopkontak yang cocok akan
mengurangi risiko sengatan listrik.
5. Hindari sentuhan tubuh dengan permukaan
yang terbumi atau dibumikan seperti pipa,
radiator, kompor, dan kulkas. Risiko sengatan
listrik bertambah jika ada bagian tubuh Anda yang
menyentuh bumi atau tanah.
6. Jangan membiarkan mesin listrik kehujanan
atau basah. Air yang masuk ke dalam mesin listrik
akan meningkatkan risiko sengatan listrik.
7. Jangan menyalahgunakan kabel. Jangan
sekali-kali menggunakan kabel untuk
membawa, menarik, atau mencabut mesin
listrik dari stopkontak. Jauhkan kabel dari
panas, minyak, tepian tajam, atau bagian
yang bergerak. Kabel yang rusak atau kusut
memperbesar risiko sengatan listrik.
