General Power Tool Safety Warnings
WARNING: Read all safety warnings, instructions, illustra-
tions and specifications provided with this power tool. Failure to
follow all instructions listed below may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
WARNING:
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) 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.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
2) Electrical safety
a) 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.
b) 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 ground-
ed.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d) 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.

e) When operating a power tool outdoors, use an extension cord suit-
able for outdoor use. Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduc-
es the risk of electric shock.
3) Personal safety
a) 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 person-
al injury.
b) 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.
c) Prevent unintentional starting. Ensure the switch is in the off-posi-
tion 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 acci-
dents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situa-
tions.
f) 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.
g) 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.
h) 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.
4) Power tool use and care
a) 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.
b) 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 danger-
ous and must be repaired.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier to
control.
g) 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.

h) 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.
5) Battery tool use and care.
a) 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.
b) Use power tools only with specifically designated battery packs.
Use of any other battery packs may create a risk of injury and fire.
c) 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.
d) 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.
e) 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.
f) Do not expose a battery pack or tool to fire or excessive tempera-
ture . Exposure to fire or temperature above 40 °C may cause explosion.
g) 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.
6) Service
a) 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.

1) Before any work on the machine (e.G., Maintenance, tool change,
etc.) as well as during transport and storage, set the rotational
direction switch (forward/reverse switch ) to the center position.
Unintentional actuation of the on/off trigger can lead to injuries.
2) Hold power tool by insulated gripping surfaces, when performing
an operation where the cutting accessory or fastener may contact
hidden wiring. Cutting accessory and fasteners contacting a “live”
wire may make exposed metal parts of the power tool “live” and could
give the operator an electric shock.
3) Wear ear protectors and goggles when impact drilling. Exposure
to noise can cause hearing loss.
4) Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one’s health and
cause allergic reactions, lead to respiratory infections and/or
cancer. Materials containing asbestos may only be worked by special-
ists.
– please always keep the working place clean and well-ventilated.
– it is recommended to wear dust masks that are specially designed
to filter out microscopic particles.
Observe the relevant regulations in your country for the materials to be
worked.
5) Use only sockets and other accessories specifically designed for
use on impact wrenches and drivers. Other sockets and accessories
might shatter or break causing injury.
6) Always use common sense and be cautious when using tools. It
is not possible to anticipate every situation that could result in a
dangerous outcome. Do not use this tool if you do not understand
these operating instructions or you feel the work is beyond your capa-
bility.
