WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised 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 diff erent
applications, with diff erent accessories or poorly maintained, the vibration emission may diff er. This may signifi cantly 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 signifi cantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the eff ects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
WARNING Read all safety warnings, instructions,
illustrations and specifi cations provided with this power
tool. Failure to follow all instructions listed below may result
in electric shock, fi re and/or serious injury.
IMPACT WRENCH SAFETY WARNINGS
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. Exposure to noise can cause hearing
loss.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use protective equipment. Always wear safety glasses when
working with the machine. The use of protective clothing is
recommended, such as dust mask, protective gloves, sturdy
non-slip footwear, helmet and ear defenders.
The dust produced when using this tool may be harmful to
health. Do not inhale the dust. Wear a suitable dust
protection mask.
Do not machine any materials that present a danger to
health (e.g. asbestos).
Switch the device off immediately if the insertion tool stalls!
Do not switch the device on again while the insertion tool is
stalled, as doing so could trigger a sudden recoil with a high
reactive force. Determine why the insertion tool stalled and
rectify this, paying heed to the safety instructions.
The possible causes may be:
• it is tilted in the workpiece to be machined
• it has pierced through the material to be machined
• the power tool is overloaded

Do not reach into the machine while it is running.
The insertion tool may become hot during use.
• when changing tools
• when setting the device down
Chips and splinters must not be removed while the machine
is running.
When working in walls ceiling, or fl oor, take care to avoid
electric cables and gas or waterpipes.
Clamp your workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
Remove the battery pack before starting any work on the
machine.
Do not dispose of used battery packs in the household
refuse or by burning them. AEG Distributors off er to retrieve
old batteries to protect our environment.
Do not store the battery pack together with metal objects
(short circuit risk).
Use only System GBS chargers for charging System GBS
battery packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store
only in dry rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under
extreme load or extreme temperatures. In case of contact
with battery acid wash it off immediately with soap and
water. In case of eye contact rinse thoroughly for at least 10
minutes and immediately seek medical attention.
Warning! To reduce the risk of fi re, personal injury, and
product damage due to a short circuit, never immerse your
tool, battery pack or charger in fl uid or allow a fl uid to fl ow
inside them. Corrosive or conductive fl uids, such as
seawater, certain industrial chemicals, and bleach or bleach
containing products, etc., can cause a short circuit.
SPECIFIED CONDITIONS OF USE
The cordless impact wrench can be used to tighten and

OPERATION
Note: It is recommended after fastening to always check
the torque with a torque wrench.
The fastening torque is aff ected by a wide variety of factors
including the following.
• State of battery charge – When the battery is discharged
voltage will drop and the fastening torque will be reduced.
• Operation at speeds – Operating the tool at low speeds
will cause a reduction in fastening torques.
• Fastening position – Holding the tool or the driving
fastener in various angles will aff ect the torque.
• Drive accessory/socket – Failure to use the correct size
accessory or socket, or a non-impact rated accessory may
cause a reduction in the fastening torque.
• Use of accessories and extensions – Depending on the
accessory or extension fi tment can reduce the fastening
force of the impact wrench.
• Bolt/Nut – Fastening torques may diff er according to the
diameter of the nut or bolt, the class of nut/bolt and the
length of nut/bolt.
• Condition of the fastener – Contaminated, corroded, dry or
lubricated fasteners may vary the fastening torques.
• Condition and base material – The base material of the
fastener and any component in between the surfaces may
eff ect the fastening torque (dry or lubricated base, soft or
hard base, disc, seal or washer between fastener and
base material).
IMPACTING TECHNIQUES
The longer a bolt, screw, or nut is impacted, the tighter it will
become.
To help prevent damaging the fasteners or workpieces,
avoid excessive impacting.
Be particularly careful when impacting smaller fasteners
because they require less impacting to reach optimum
torque.
Practice with various fasteners, noting the length of time
required to reach the desired torque.
Check the tightness with a hand-torque wrench.
If the fasteners are too tight, reduce the impacting time.
If they are not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under the
head of the fastener aff ects the degree of tightness.
The torque required to loosen a fastener averages 75% to
80% of the tightening torque, depending on the condition of
the contacting surfaces.
On light gasket jobs, run each fastener down to a relatively
light torque and use a hand torque wrench for fi nal
tightening.
BATTERIES
Battery packs which have not been used for some time
should be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure
to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept
clean.
For an optimum life-time, the battery packs have to be fully
charged, after used.
To obtain the longest possible battery life remove the battery
pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C
and away from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
BATTERY PACK PROTECTION LI-ION BATTERY
The battery pack has overload protection that protects it
from being overloaded and helps to ensure long life.
Under extreme stress the battery electronics switch off the
machine automatically. To restart, switch the machine off
and then on again. If the machine does not start up again,
the battery pack may have discharged completely. In this
case it must be recharged in the battery charger.
TRANSPORTING LITHIUM BATTERIES
Lithium-ion batteries are subject to the Dangerous Goods
Legislation requirements.
Transportation of those batteries has to be done in
accordance with local, national and international provisions
and regulations.
• The user can transport the batteries by road without
further requirements.
• Commercial transport of Lithium-Ion batteries by third
parties is subject to Dangerous Goods regulations.
Transport preparation and transport are exclusively to be
carried out by appropriately trained persons and the
process has to be accompanied by corresponding experts.
When transporting batteries:
• Ensure that battery contact terminals are protected and
insulated to prevent short circuit.
• Ensure that battery pack is secured against movement
within packaging.
• Do not transport batteries that are cracked or leak.
