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 atmospheres, such as in the presence of flammable
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. Unmodified 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 electric 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 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 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.
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 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 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.
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.
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.
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.
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.
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 equipments by the tool operators and by other persons 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 adjustments, 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 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,
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.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
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.
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
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.
Battery tool use and care
1. Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
2. Use power tools only with specifically designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
3. 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 terminals together may cause burns or a fire.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
5. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries
may exhibit unpredictable behaviour resulting in
fire, explosion or risk of injury.
6. Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
7. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instructions. Charging improperly or at temperatures
outside the specified range may damage the
battery and increase the risk of fire.
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 tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
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.
Be sure the bit is secured in place before operation.
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.
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.
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.
Keep hands away from moving parts.
Do not leave the tool running. Operate the tool
only when hand-held.
Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
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.
Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier
safety data.
WARNING: DO NOT let comfort or familiarity
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.
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
