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 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.
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.
IMPACT DRIVER SAFETY WARNINGS
Wear ear protectors. Exposure to noise can cause hearing loss.
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.
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 floor, 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 offer 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 fire, personal injury, and product damage due to a
short circuit, never immerse your tool, battery pack or charger in fluid or allow a
fluid to flow inside them. Corrosive or conductive fluids, 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 loosen nuts and bolts
wherever no mains connection is available.
Do not use this product in any other way as stated for normal use.

OPERATION
Note: It is recommended after fastening to always check the torque with a
torque wrench.
The fastening torque is affected 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 affect 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
fitment can reduce the fastening force of the impact wrench.
• Bolt/Nut – Fastening torques may differ 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 effect 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
affects 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 final 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.
Check with forwarding company for further advice
