4.
Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
NOTE: The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
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.
NOTE: The declared vibration total value(s) may also
be used in a preliminary assessment of exposure.
WARNING: The vibration emission during
actual use of the power tool can differ from the
declared value(s) depending on the ways in which
the tool is used especially what kind of workpiece
is processed.
5.
6.
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.
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.
WARNING: Be sure to identify safety mea-
sures to protect the operator that are based on an
estimation of exposure in the actual conditions of
use (taking account of all parts of the operating
cycle such as the times when the tool is switched
off and when it is running idle in addition to the
trigger time).
7.
8.
Use of power supply via an RCD with a rated resid-
ual current of 30 mA or less is always recommended.
Power tools can produce electromagnetic fields
(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.
EC Declaration of Conformity
For European countries only
9.
Do not touch the power plug with wet hands.
The EC declaration of conformity is included as Annex A
to this instruction manual.
10. If the cord is damaged, have it replaced by the
manufacturer or his agent in order to avoid a
safety hazard.
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 influence of drugs, alcohol or med-
ication. A moment of inattention while operating
power tools may result in serious personal injury.
SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, 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.
2.
3.
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.
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.
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.
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.
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 flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
5.
6.
Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
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.
3.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
7.
8.
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.
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. Unmodified plugs and
matching outlets will reduce risk of electric shock.
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.
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
ENGLISH
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.
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.
Service
1.
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.
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.
3.
Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping sur-
faces, when performing an operation where
the cutting accessory may contact hidden wir-
ing 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.
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.
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.
Power tool use and care
1.
2.
3.
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.
5.
6.
Be sure the bit is secured in place before operation.
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.
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.
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.
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 difficult.
4.
5.
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.
8.
9.
Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
Maintain power tools and accessories. Check for
misalignment or binding of moving parts, break-
age 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.
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 fly out and
injure someone seriously.
6.
7.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
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.
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 different from those intended could
result in a hazardous situation.
14. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion 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.
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.
