8� DO NOT USE ACCUMULATOR BATTERIES if they are damaged
or if liquid leaks out of the cells� If the battery liquid comes
into contact with your skin, immediately flush the area with
water and monitor the skin's reaction� Seek medical attention
if needed� If it comes into contact with your eyes, flush them
with lots of water and immediately seek medical attention�
9� If you are charging a fully discharged battery or if you stop
charging the battery before it is fully charged, you must count
each of these cycles as an entire charging cycle�
Note on Lithium-ion (Li-Ion) batteries
• These types of batteries do not have a memory effect, in other
words, the batteries can be charged at any state of discharge� If
you take the batteries out of the charger prior to fully charging
them, it will not damage them�
• Each Li-Ion battery is equipped with deep discharge protec-
tion� If the voltage falls (due to overloading or discharge) be-
low the monitored range, the electronic circuit will disconnect
the cells� The machine will then either work intermittently or
not at all� You must reduce machine load or recharge the bat-
tery�
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�
Commissioning
Inserting and removing a battery
Insert the battery (B1) into the shaft on the bottom side of the
machine handle all the way� Pull on the battery to make sure it is
fitted properly�
To remove the accumulator (B1) from the machine, push on the
accumulator clamp (B2) and pull the accumulator out�
Turning the device ON
Pressing on the switch button (B1) and gradually pushing on it will
regulate speed� If you press the switch button (B1) the LED work
areal light (5) will automatically switch on� It is used to light up the
work space directly in front of the machine –clamped device in the
chuck�
Turning the device OFF
Release the switch button (B1)� The rundown of the spindle with
the chuck is decreased using the brake after being turned off�
Lower speed is suitable for guiding the screw/bolt into the mate-
rial� Higher speed is suitable for tightening the screw/bolt into the
material or for drilling�
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 (B2) 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�
Changing the speed
Use the shift button (3) to change speed�
1� Low speed:
move the button away from the chuck – the "1"
letter appears
2� High speed: move the button towards the chuck – the "2"
letter appears
Work mode selection
You can set up tightening, impact free drilling or impact drilling by
turning the mode switch (4b) to the relevant symbol� You may also
use the torque set function for batch or gentle tightening when
setting up the drive mode� The machine has a maximum torque
available when setting the impact free drilling mode� Impact drill-
ing makes drilling more efficient, e�g� when drilling into brick or
other such hard construction materials�
Attention! Only change the tightening/drilling/impact drilling
modes while the machine is idle!
Always use only drill bits designed for impact drilling when drilling
in this manner�
Tightening
Symbol
= suitable for tightening�
Setting up torque
The function for setting up torque can be used only if the machine
or set collar (6b) is set to tightening mode�
Turning the set collar for torque set-up (4a) to the relevant symbol
will set the required torque�
Tightening
Symbol
1
= lowest tightening torque
Symbol
23 = highest tightening torque
Impact free drilling
Symbol
= suitable for driving, drilling into metal, wood
etc�
Impact Drilling
Symbol
= suitable for impact drilling into brick�
Mounting and releasing tools
Turning the chuck mounting case (6) opens and closes the jaws
between which you place the working tools (drill bit, bit holder
etc�)� The machines are automatically equipped with a spindle stop,
which makes changing the tool using only one hand in the desired
direction very simple�
