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.
Check with forwarding company for further advice

 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.

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.
