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.

Stefan Haug
Anwendungstechnik
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
New battery packs reach full loading capacity after 4 - 5
chargings and dischargings. 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, after use, the battery packs have
to be fully charged.
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
In extremely high torque, binding, stalling and short circuit
situations that cause high current draw, the tool will vibrate
for about 2 seconds and then the tool will turn OFF.
To reset, release the trigger.
Under extreme circumstances, the internal temperatur of the
battery could become to high. If this happens, the battery
will shut down.
Place the battery on the charger to charge and reset it.
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.
