DOUBLE INSULATION
Only for EU countries
Do not dispose of electric equipment
together with household waste material! In
observance of the European Directive, on
Waste Electric and Electronic Equipment
and its implementation in accordance with
national law, electric equipment that have
reached the end of their life must be col-
lected separately and returned to an envi-
ronmentally compatible recycling facility.
Intended use
The tool is intended for chiselling work in concrete,
brick, stone and asphalt as well as for driving and com-
pacting with appropriate accessories.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
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-oper-
ated (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 conditions. 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.
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 unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.
7. Use of power supply via an RCD with a rated resid-
ual current of 30 mA or less is always recommended.
8. 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.
9. Do not touch the power plug with wet hands.
10. If the cord is damaged, have it replaced by the
manufacturer or his agent in order to avoid a
safety hazard.

3ENGLISH
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 medication. 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 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.
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 o󰀨. 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 adjustments, changing accesso-
ries, or storing power tools. Such preventive safety mea-
sures reduce the risk of starting the power tool accidentally.
4. 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.
5. Maintain power tools and accessories. Check for
misalignment or binding of moving parts, break-
age 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.
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 di󰀨erent
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
grasping 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 entanglement of cloth work
gloves in the moving parts may result in personal injury.
Service
1.
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.
2. Follow instruction for lubricating and chang-
ing accessories.
Electric Breaker 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 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.
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 recommended 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.

4ENGLISH
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 operat-
ing. The bit could y out and injure someone seriously.
13. Do not touch the bit, parts close to the bit, or
workpiece 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 inhalation and
skin contact. Follow material supplier safety data.
15. Do not touch the power plug with wet hands.
16.
Before operation, make sure that there is no buried
object such as electric pipe, water pipe or gas pipe
in the working area. Otherwise, the bit may touch them,
resulting an electric shock, electrical leakage or gas leak.
17. Do not operate the tool at no-load unnecessarily.
