Storing lithium-ion batteries
• Store fully charge batteries in a dry and dust-free environment
at an ambient temperature between 5 °C and 40 °C� If you are
not using the batteries for a longer period of time, we recom-
mend you charge them fully once every three months�
• Keep the battery contacts clean� Do not store the replacement
battery together with metal items as it may cause a short cir-
cuit�
• It is always necessary to charge batteries that were not used for
a long time prior to use�
Transporting lithium-ion batteries
As per legal regulation, lithium-ion batteries fall into the hazard-
ous load category� These batteries must be transported while com-
plying with local, national, as well as international guidelines and
regulations�
• Consumers may transport these batteries on public roads
without a problem�
• Commercial transportation of lithium-ion batteries by trans-
portation companies must comply with the regulation on
hazardous load transportation� Only trained personnel may
carry out the preparation and the actual transport� The entire
process must have expert supervision�
The following must be maintained during battery transpor-
tation:
• Make sure that contacts are protected and isolated to prevent
a short circuit�
• Be careful so that a large number of batteries do not move
around or fall and collapse during transport�
• Damaged and leaking batteries cannot be transported�
Please contact your carrier for additional information�
Warning!!
It is not expected for the user to perform any service repairs on the
charger� There are no spare parts inside the charger, which users
could repair on their own� It is necessary to bring the charger to
your nearest authorised service centre to prevent damage to spare
parts, which are sensitive to static electricity, for example�
Always use the right set of batteries (the set delivered with the
tools or a replacement set recommended by Narex s�r�o�)� Never
use any other sets of accumulator batteries because they could
damage your tools and cause a hazardous situation�

Function principle

A spindle with the tool is powered by an electric motor with a
transmission and an impact mechanism�
The work process is divided into two phases:
1� Driving a screw
2� Tightening (the impact mechanism is activated)
The impact mechanism is activated only once the screw joint
is fixed – the motor is engaged� The impact mechanism thereby
changes the power of the motor to even the rotary impacts�
This process is reversed when loosening screws�

Instructions for use

Mount the device, which must be turned off, onto a nut/screw.
The torque depends on how long the impacts last� Maximum
torque is based on individual torques reached by the impacts� Max-
imum torque is reached once impacts run for ca� 3 seconds� From
this moment on, the torque increases only slightly; however, it
noticeably heats the impact mechanism� Overheating wears down
the impact spare parts and uses up higher amounts of lubrication�
The impact period must be designated for each required torque�
The actual tightening torque reached must be continuously veri-
fied using a torque key�
The default status of the screw joint and its technical specification
is always an important factor for reaching the tightening or loosen-
ing device performance�
There are two typical joints to be used:
Hard joint:
Using a screw joint to tighten two or more (usually) steel parts,
which do not flex, nor are they deformed in any way as a result of
tightening pressure�
Soft joint:
Using a screw joint to tighten two or more parts, where at least
one part is from such material or is made in such a way that the
tightening pressure deforms or flexes it�

Commissioning

Inserting and removing a battery
Insert the battery (1) into the shaft on the bottom side of the ma-
chine handle all the way� Pull on the battery to make sure it is fitted
properly�
To remove a battery (1) from the machine, push on both battery
clamps (2) and pull the battery out�
Turning the device ON
Pressing on the switch button (3) and gradually pushing on it will
regulate speed� If you press the switch button (3), the LED work ar-
eal light (6) will automatically switch on� It is used to light up the
work space directly in front of the machine – clamped device�
Turning the device OFF
Release the switch button (3)� The rundown of the spindle is de-
creased using the brake after being turned off�
A lower speed is suitable for guiding the nut/screw/bolt/drill bit
etc� into the material�
ATTENTION! Long-term use of variable rotation speeds
is not recommended. It can lead to switch button dam-
age.
Changing the rotation direction
Using the turn direction switch (4) changes the rotation direction:
• Push down from right to left – clockwise�
• Push down from left to right – counter-clockwise�
• Button is in between – protection against accidental start�
Attention!
If you wish to change the position of the shift button, first check
that the switch button is released�
Note:
You may hear a loud click when you first use the device after
changing the rotation direction� This is normal and does not indi-
cate a problem�
Tool fastening
When mounting tools, always make sure that these attachments
are mounted on a 3/8" spindle (5) or to a transfer adapter all the
way (10)�

"TRAFFIC LIGHT" LED indicator (7)

Battery charge status (capacity) indication:
Activates automatically once you press the switch button (3) and
switches off after approx� 3 seconds� The following LEDs light up
depending on the state of charge (capacity) of the accumulator:
• Accumulator is fully charged: all three status LEDs light up –
green, yellow and red�
• Accumulator capacity has dropped below ca� 60%: only two
status LEDs light up – yellow and red�
• Accumulator capacity has dropped below ca� 30%: only one
status LED lights up – red�
Indication of Reversible Defects
• Indication of low accumulator voltage – can occur when the
accumulator voltage reaches dangerously low levels that
could prevent repeated, proper and safe recharging� The con-
trol system will automatically disconnect the motor and a red
status LED will start flashing; release the switch and press it
again� If the problem persists, take the accumulator out of the
machine and place it in the charger to recharge it� Insert the
other (spare) accumulator into the machine and proceed with
your work�
