Important notes for charging:
1. The longest service life and the best capacity can be reached if the
accumulators are charged at the ambient temperature ranging
from 18 °C to 24 °C.
DO NOT RECHARGE
the accumulators at the
temperature below 4.5 °C or over 40.5 °C. This is very important. You
can thus prevent serious accumulator damage.
2. Recharge the accumulators in time, before they are discharged ful-
ly. If you mention that your accumulator-operated device loses its
power, stop it and recharge the accumulator in a suitable charger,
otherwise the accumulators can be damaged permanently (irre-
versibly).
3. The charger was designed to fast charge battery pack between 0 °C
and 45 °C. If the battery pack just inserted is too cold or too hot, the
charger will not charge it and only the green and the red LED in-
dicators will blink alternatively and continuously. After the battery
pack temperature fit standard temperature range, the fast charging
procedure will be started automatically.
4. If the accumulators cannot be charged duly (the red pilot lamp is on
intermittently):
• Check accumulator contact areas for possible pollution. Clean
them by a cotton swab and spirit, if necessary.
• If the accumulators still cannot be charged correctly, send or
hand over the charger (incl. the accumulators) to the nearest
authorized service centre.
5. Under certain conditions, with the charger plugged into the power
source, the exposed charging contacts inside the charger can be
shorted by foreign material. Foreign materials of a conductive na-
ture such as, but not limited to, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Unplug charger before attempting to clean.
6. If several charging operations are performed consecutively, the
charger can become warm. It is normal and does not indicate any
technical defect.
7. Prevent leak of liquid into the charger to avoid electrical accident. If
you want to facilitate accumulator cooling after its use, do not place
it in a warm(ed) environment.
8. The accumulators can remain placed in the switched-on charger
without any damage to themselves or to the charger. The accumu-
lators remain in the fully charged state in the charger.
DO NOT LET
the charged accumulators in the charger disconnected from the
power supply.
9.
DO NOT USE THE BATTERY PACK
if it is damaged and liquid is
leaked from the battery pack cells. If this leakage gets on your skin,
please wash the affected part immediately and observe possible
skin reaction. If necessary, please seek medical attention.
10. If you charge the not yet fully discharged accumulator or if you
terminate accumulator charging before the fully charged state is
reached, each such cycle has to be considered one complete cycle
of charging.
Notes for lithium (Li-Ion) accumulators
• This battery pack type does not suffer form the memory effect, it
means that the accumulators can be charged in any state of charg-
ing. If you remove the battery pack from the battery compartment
before the battery is fully charged, it will not cause any damage to
the battery.
• The Li-Ion accumulator is equipped by protection from deep dis-
charge. If the voltage drops below the preset limit (by overload or
discharge), the electronic system disconnects the accumulators.
The device then works intermittently or does not work at all. It is
necessary to reduce machine load or to recharge the accumulator.
Accumulator storage
Store the accumulators in the fully charged state in a dry and dustfree
room at the ambient temperature ranging preferably from 5 °C to 40 °C.
If you do not use the accumulators for a longer time period, it is rec-
ommended to charge the accumulators fully once in three months as
a minimum!
Warning!!
The charger is not user serviceable. There are no user serviceable parts
inside the charger. Servicing at the closest Authorized Service Center is
required to avoid damage to static sensitive internal components.
Always use correct battery pack (pack supplied with the tool or the
replacement pack recommended by the manufacturer, the company
Narex s.r.o.) Never install another battery pack type. It will ruin your tool
and may create a hazardous condition.
Putting into operation
Switching-on
By depressing the operating push button (3) and by its holding you can
control speed smoothly.
Switching-off
By releasing the operating push button (3). Runout of the spindle with
the chuck is reduced by the activated brake.
Lower speed is suitable for guiding the bolt/screw to the material. High-
er speed is suitable for screwing the bolt/screw into the material or for
drilling into the material.
Attention!
Long-time use of variable rotating speed is not recommended as its can
result in operating push button damage.
Changed direction of rotation
Direction of rotation is changed by the change over switch of the sense
of rotation (4):
· By pushing from the right to the left – right run.
· By pushing from the left to the right – left run.
· Push button in the interposition – protection from unintentional
switching.
Attention!
If you wish to change position of the change over switch, check at first
that the operating push button is released.
Note:
During first use of the device and during the first change of the sense
of rotation a loud click can be heard. It is a normal phenomenon which
cannot be considered any problem.
Speed changing
Speed changing is carried out by the sliding switch (5).
1. low speed:
move the switch towards the chuck – the
figure “
1
“ will appear
2. high speed:
move the switch from the chuck – the
figure “
2
“ will appear
Torque setting
The necessary torque can be set by swiveling the adjusting ring (6) to-
wards the relevant symbol.
Screwing
Symbol
1
= min. torque
Symbol
20
= max. torque for screwing
Drilling
Symbol
= max. torque
Tool clamping and releasing
By swiveling the clamping chuck sleeve (7), you open and close the
clamping jaws, which the working tool (bit, bit holder, etc.) is inserted
into. The devices are equipped by automatic spindle arrest (locking)
facilitating tool replacement, by using one hand only in the requested
direction.
