GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings, instructions,
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.
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.
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 grounded.
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 suitable
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 reduces
the risk of electric shock.
NOTE: The term “residual current device (RCD)” can be replaced by the term
“ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker
(ELCB)”.
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 personal 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-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.

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 situations.
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 dangerous 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

5
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 temperature.
Exposure to fire or temperature above 130 °C may cause explosion.
NOTE The temperature „130 °C“ can be replaced by the temperature „265
°F“.
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.
b) Never service damaged battery packs. Service of battery packs should only
be performed by the manufacturer or authorized service providers.
EXTRA SAFETY INSTRUCTIONS CONCERNING IMPACT WRENCH
1. Wear hearing protection when impact screwing. Exposure to loud noise can lead
to hearing loss.
2. Secure the workpiece! A workpiece securely held by a clamping device or vice is
much safer than one held in your hand.
3. Hold the power tool firmly. High torques can occur for brief periods while
tightening and loosening screws.
4. Wait until the power tool has come to a stand-till before putting it down. The tool
can jam his leading to loss of control of the power tool.
5. Hold the power tool by the insulated gripping surfaces, when performing an
operation where the screw could come into contact with hidden wiring. Contact
between the screw or attached tool and a live wire may cause exposed metal
parts of the power tool to become live and give the operator an electric shock
INTENDED USE
The impact wrench can be used to tighten and loosen nuts and bolts. As a control
measure, always check the tightening torque with a torque wrench. Do not use this
product in any other way as stated for normal use. Not observing general regulations
in force and instructions from this manual does not make the manufacturer liable for

NOISE/VIBRATION INFORMATION
Measured sound values determined according to EN 62841.
Wear hearing protection!
Vibration total values (triax vector sum) determined according to EN 62841:
The vibration emission level given in this information sheet has been measured in
accordance with a standardized test given in EN 62841 and may be used to compare
one tool with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool.
However if the tool is used for different applications, with different accessories or
poorly maintained, the vibration emission may differ. This may significantly increase
the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the
times when the tool is switched off or when it is running but not actually doing the job.
This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of
vibration such as: maintain the tool and the accessories, keep the hands warm,
organisation of work patterns.
Vibration risk limitation suggestions:
1) Wear glove during operation
