Operation - AEG BSS18C2 Original Instructions Manual

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 driver 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.
RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
• Injury caused by vibration.
Hold the product by designated handles and restrict
working time and exposure.
• Exposure to noise can cause hearing injury.
Wear ear protection and limit exposure.
• Injury due to fl ying debris
Wear eye protection, heavy long trousers, gloves and
substancial footwear at all times.
• Inhalation of toxic dusts.

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 driver.
• 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.
NOTES FOR LI-ION BATTERIES
Use of Li-Ion 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 protection for Li-Ion Akkus
In extremely high torque, binding, stalling and short circuit
situations that cause high current draw, the tool will vibrate for
about 5 seconds, the fuel gauge will fl ash,and then the tool
will turn OFF. To reset, release the trigger.
Under extreme circumstances, the internal temperature of the
battery pack could raise too much. If this happens, the fuel
gauge will fl ash until the battery pack cooled down. After the
lights go off , the work may continue.
Transport of 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.
