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,
18
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
temperature. Exposure to fire or temperature above 130 °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.
b ) Never service damaged battery packs. Service of
battery packs should only be performed by the manufacturer or
authorized service providers.
Impact Wrench Safety Warnings ‑ All Operations
• Hold the power tool by insulated gripping surfaces, when
performing an operation where the fastener may contact
hidden wiring. Fasteners contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the
operator an electric shock.
• Wear ear protectors during use. Exposure to noise can cause
hearing loss.

WARNING: Impact wrenches are not torque wrenches.
DO NOT use this tool for tightening fasteners to specified
torques. An independent, calibrated torque measurement device
such as a torque wrench should be used when under tightened or
over tightened fasteners can lead to the failure of the joint.
